Description

Temporary construction and originally construction the outer layer of a 2-layer wall type underground road building method}

The present invention relates to the field of construction, in particular, in order to form a subterranean roadway, after the construction of the cladding material in contact with the covering portion of the structural wall, the upper slab is pre-installed and excavated inside to reinforce or construct the lower slab and the central wall and columns Then, the present invention relates to a method of constructing an underground road using a temporary wall construction method of a temporary structure and a main structure.

Underground roadway means a structure that is provided in the basement in either direction of a place with a lot of traffic, such as an intersection, or is installed for smooth traffic in a place where the topographical conditions are not suitable for ground operation.

Recently, there has been a tendency to demolish roads used in elevated roads and build underground roads, because elevated roads are hurting the city's aesthetics and are subject to civil complaints due to noise and pollution.

In the installation of the underground roadway, the conventional roadway has been constructed by a conventional method using a temporary material of H-beams, a mold beam and a perforated plate.

According to the conventional method for constructing such underground roadways, the traffic flows are disturbed due to the accumulation of materials on the road during the underground excavation and construction, and the displacement of the surrounding buildings due to dehydration or ground relaxation during excavation In addition to the various civil complaints caused by the construction method by the temporary facility and the rehabilitation caused by noise and scattering dust, the construction period has also been exposed to a long time.

On the other hand, there is a TUS method (Patent Registration No. 10-1187369) as a prior art in addition to the conventional conventional method described above, the length of the CIP bulb of the central wall or column reaches to the surface, the problem of waterproof construction and the installation of the internal support It can only be constructed in the point of trouble, and the soil layer, CIP bulbs cannot be overlapped with each other and can not function as the order. In the case of long underground roads, there is no facility for internal excavation and concrete casting. There are some problems with lighting.

Domestic Patent No. 10-1187369

In the drawings, reference numeral 131 denotes a side wall formed by the CIP bulb 100 and the new CIP bulb 115, and reference numeral 130 also denotes a central wall or column formed by the CIP bulb 100 and the new CIP bulb 115. In the present invention, the unit consisting of the CIP bulb 100 and the new CIP bulb 115 is referred to as CIP bulb 100, and is embedded in a row by the CIP bulb 100 and is located in the center of the basement. The sidewalls on both sides are divided and denoted by reference numerals.

On the other hand, when forming the CIP bulb 100, one side of the reinforcing mesh (referring to the inner side where the wall is formed, hereinafter referred to as one side) on the panel 102 such as plywood to be in a state bound to the band reinforcement concrete When pouring, concrete should not be placed inside the panel 102 such as plywood, and the chord 103 is partially arranged inside the band reinforcing bar, which is the horizontal reinforcement bar and the CIP bulb of the inner wall reinforcing bar 181. This is to facilitate the interconnection of the reinforcing bars arranged after the strip reinforcing bars of (100).

In addition, it is good to configure the anchor bolt for connecting the corner reinforcement 160 in advance. This is to facilitate the installation immediately when installing the corner reinforcement.

In addition, the panel 102 such as plywood is tied to the band reinforcement on both sides (right and left sides where the center is formed) of the reinforcement mesh so that concrete is not poured into the panel 102 such as plywood when the concrete is placed. It should be, but the chord 103 is partially disposed inside the band reinforcing bar.

This is because the CIP bulb 100 in the central portion is made of overlapping joints but does not lead to reinforcing bars, so that the reinforcement bars and the band reinforcing bars are bundled to form an integral structure.

In addition, in the inner wall (180, 180 '), two PC strands 123 are disposed in contact with the main reinforcing bars on one side corner of the reinforcing wire mesh, and the CIP bulb 100 is disposed only at a certain length, and the middle reinforcement of the strip reinforcing rods 120 in the center 130. In connection with the two PC strands 123 is placed only a certain length of the CIP bulb 100.

Here, the role of the two PC strands 123 in contact with the reinforcing wire one side corner both side reinforcing bars, even if the earth anchor 210 is not installed between the corner reinforcement provided in the outermost right corner of the upper slab and the final digging line. As a structure for enhancing the load capacity of the CIP bulb 100 to cope with external force absence force, it is disposed every CIP bulb 100, two strands of PC strands 123 in the central portion is formed on both sides of the dodlock pattern formwork. This is to prevent the thinner CIP bulb 100 from generating buckling due to external member force.

On the other hand, the tensioning time of the PC strand is settled in the upper slab when the rebar assembly of the upper slab is completed, thus acting as a more tightly cohesion between the upper slab and the CIP, and can also reduce the corner angle of the right corner. .

However, these CIP bulbs 100 are available only in the soil layer and are subject to constraints that are impossible in rock sections.

This is because the auger's equipment that excavates the ground is not able to puncture the rock. In this case, the bulb 100 is formed together with the internal excavation using the T4 equipment that can be perforated to the rock side every 2.0m. After forming the bulb 100, construct the upper slab (140.150) and excavate to the rock section to equip the CIP support anchor 107 and continue the internal excavation, but only to the earth and sand layer from the bottom of the lower slab cast concrete When cutting the rock (A) to continue the CIP reinforcement and poured concrete mixed with the powder waterproofing agent, a solid inner wall (180, 180 ') is formed.

One side  Upper Slab Construction Process- S20

When the installation of the CIP bulb 100 is completed through the above-described process (S10), the section of the road section as shown in FIG. 2 is separated, and in this state, the whole compartment is divided by the CIP bulb 100 in this state. It will be understood that either side of the third divided by the width source as a process for forming the upper slab first.

To this end, as shown in FIG. 3, the central portion of the upper half of the upper slab width source (as described above, the entire portion dividing the center of the wall formed of the CIP bulbs is referred to as the central portion and denoted as 130 in the drawing). It also includes a pillar type formed by the bulb) (130) in one side of the road portion near the excavated H-peg to excavate the asphalt layer and soil.

At this time, it is assumed that the concrete PC1 earth plate 104, which is applied in the fourth embodiment, is installed as an H-pile soiling facility.

In this way, after the trench work is carried out to a certain depth, the floor slab is equipped with concrete and formwork, and then the upper slab is installed.

At this time, the anchor bolt for connecting the corner reinforcement 160 may be configured in advance. This is to facilitate the installation immediately when installing the corner reinforcement 160.

In the present invention, the upper slab is divided into three equal parts and the sequential pouring process, respectively, as shown in Figures 3 to 5, the upper part of the right side when viewed in the drawings (Fig. 3) for the understanding of the implementation of the present invention. Named slab on one side of upper slab and denoted by reference numeral 140. Named slab on the opposite side as other upper slab, denoted by reference numeral 140 'and named center slab as center-side upper slab. Notation was divided into.

At this time, the reinforcing bar of one side upper slab 140 can be arranged in zigzag so as not to be connected at one place for connecting the reinforcement with the center side upper slab 150 in contact with the neighbor, and after construction of the one side upper slab 140 Install a protective mortar.

As such, after placing the upper slab 140 on one side, a trench construction (S30) for placing the other upper slab 140 ', which will be described later, is performed, but the upper upper slab does not interfere with the flow of traffic before. Cover the surface of the (140) must go through a cover process.

On the other hand, in the case of covering the soil to cover the zigzag reinforcement of the zigzag reinforcement of the upper slab 140 and the central side of the upper slab 150 while covering the soil as a separate mud facility H pile 90 one flange After making a plurality of drilling holes 92 in the back and a certain distance back from the joint, the facility is installed, but a plurality of the transverse in such a way to couple the anchor body 91 connected to the reinforcement with the bolt 93 at the drilling hole 92 position After installation, they are stacked and installed to the ground in the same way.

When the facility is installed in such a way, when the upper slab 150 is destroyed in the central side, a separate soil barrier facility installed at the construction of the upper upper slab 140 serves as the earth wall so that the trench of the central upper slab 150 is removed. It becomes easy.

On the other hand, in the construction of one side upper slab 140, unlike the above, the construction of the trench can be constructed by the method of 1/2 of one side and the other side with respect to the center part by the circumstances of the road.

The other side  Upper Slab Construction Process- S30

This process is after pouring the one side upper slab 140 by the one side upper slab construction step (S20), and then cover the upper surface of one side upper slab 140 so that the flow of traffic is not hindered, then the other side, one side As seen from the side (FIG. 4) opposite the upper slab 140, it refers to a process of constructing the trench to pour the upper slab on the left side (the other upper slab 140 ').

In this way, the periphery of the periphery is carried out to pour the other upper slab 140 ', and then the other upper slab to the upper side for constructing the underground driveway by casting the other upper slab 140' as shown in FIG. 140,140 ') can be completed, the installation process of anchor bolts for connecting the corner reinforcement 160, the process of covering, or the H-piling and digging and earth plate installation construction method of one side upper slab (140 ) Is done in the same way.

On the other hand, the reinforcing bar of the other upper slab (140 ') is to be connected in a zigzag arrangement so as not to be jointed in one place for connecting the reinforcement with the center upper slab 150 in contact with the neighbor and the construction of the other upper slab (140') Afterwards waterproofing material and protective mortar should be installed.

Center  Upper Slab Construction Process- S40

When the installation of the one side and the other upper slab construction process (S20, S30) is completed, as shown in Figure 5 to excavate the central side of the upper road portion to remove the ascon layer and soil.

As such, when digging the center side, there is an earthquake facility in which the H pile 90 and the anchor body 91 are already connected during the construction of one side and the other upper slab (S20, S30). It is possible.

After proceeding the trench work in a predetermined depth as described above, and then install the floor-level concrete and formwork to the trench surface, the upper side slab 150 is installed.

At this time, the reinforcing bar of the upper slab is already connected in a zigzag state on one side and the other side, and the concrete is poured. After pouring, the waterproofing material and the protective mortar are constructed.

After the central upper slab 150 is installed in this manner, the bolts for pulling the H-pile 90 which were installed in one side and the other upper slab 140 and 140 'are installed together with the process of releasing the bolt H- The pile 90 will be drawn out.

In this way, the total width of the upper slab is divided into three parts in order not to place the reinforcing bar at the maximum position of the parent moment generated at the right angle part and the center part.

On the other hand, in the case of 1/2 construction, the reinforcing bar should be made in the center part, so it may be a burden due to the parent's cement. This is to reduce the size of the parent.

Corner portion  Reinforcement and Earthanka  Construction Process- S50

This process is the upper slab (140,140 ') or the inner wall (180,180) as a way to reduce the effect of the parent moment is large because the upper slab and the CIP is combined after completing the above-mentioned casting of each upper slab (140,140') To shorten the time between ').

To this end, by excavating only a part of the corner portion is to install the stiffeners 160 at regular intervals.

At this time, during the construction process (S10) and each upper slab construction process (S20, S30) for the formation of the CIP bulb 100 is to simply assembling and fastening the four stiffeners 160 to the anchor bolts already embedded.

Since the interval between the upper slab and the CIP bulb 100 is shortened due to the installed sabotage steel 160, the member force decreases, and thus the safety is further maintained, and the end surface of the sabotage steel 160 and the final excavation surface in the inner wall (180, 180 '). Earth anchors are used to reduce the length of the bridge.

The facility of Earth Anca is advantageous in terms of economical ability to reduce the member force of the inner wall (180, 180 ') and to reduce the length of the entry.

On the other hand, when using the PC strand (123) to buy a strain on the CIP bulb 100, the same effect can be obtained even without the earth anchor, it will be natural that the person using the present invention can be selectively applied. .

Reinforcement work of both bottom slab and central wall or column- S60

This process is a process for forming the underground roadway by constructing the lower slab (170, 170 ') and the central portion 130 after the above-described corner portion reinforcement and earth anchor construction process (S50) is completed.

After forming the discarded concrete and the outer sheet waterproof layer in the excavated space on both sides, the lower slab (170, 170 ') is poured into the side wall 131 and the bottom of the excavated portion.

Here, the lower slab (170, 170 ') refers to the pour body to be poured on the bottom surface of the underground driveway, as shown in the drawing, pours up to the haunche portion in contact with the inner side of the side wall (131).

After excavating the spaces on both sides as described above, when the casting process of the lower slab (170, 170 ') is completed, place the reinforcing bars on the left and right sides of the central portion 130 and tie the CIP bulb 100, which was constructed by places, with the band bars. It is possible to form a central portion 130 of the completed form by pouring the reinforcing wall 190 to be integrated.

Both sides Inner wall  Construction Process- S70

Some of the inner walls 180 and 180 'integrally connected to both sides of the lower slab and placed inward of the side wall 131 are constructed after dismantling the earth anchors connected to the lower slabs 170 and 170' and the remaining inner walls 180 ") Is constructed while demolishing the corner reinforcement 160 after some of the inner wall (180, 180 ') is cured. However, when the remaining inner wall (180 ″) is cured, it may be settled by the concrete shrinkage action, and a fine gap may be generated with the upper slabs (140, 150, 140 '), and is completed by filling the non-shrink mortar (183).

Finishing Construction Process- S80

When the above process is completed, the process of the underground driveway is completed by installing sidewalks and electric facilities, tiles and ascons inside the underground driveway.

In the construction of the underground roadway using the CIP bulb 100 through a series of processes as described above, FIG. 9 shows reinforcing bars 181 and 111 and reinforcing bars 171 and 172 of the side wall 131 and the lower slab 170. ) Is shown in the connection fixed state.

The lower slab 170 and the lower side of the side wall 131 were connected to each other so that the lower slab 170 and the lower side of the sidewall 131 were connected and fixed to the strip reinforcing rod 120 of the rebar 111 exposed by the portion to be cut. The same applies to the bottom side.

FIG. 10 shows a state in which the lower slabs 170 and 170 'and the central portion 130 are connected to each other, and a plurality of horizontal holes 101 are formed in the horizontal direction, and the horizontal slabs 101 are formed in the lower slab 170. Passed reinforcing bars (171, 172) is shown to be connected to the other reinforcing bars (171 ', 172') to be fixed to the lower slab 170 on the other side, and the stirrup reinforcing bars (173) connected to the haunch is placed have.

FIG. 11 is a cross-sectional view for fixedly connecting between one end of the upper slab 140 and 140 'and the upper end of the side wall 131. As shown in the drawing, the fixed state between the upper slab 140 and the side wall 131 on one side is shown. When the upper slabs 140 and 140 'are poured, the plurality of reinforcing bars 142, 142' / 143 and 143 'embedded in the upper slabs 140 and 140' are embedded in the CIP bulbs 100 forming the side walls 131, respectively. Among the reinforcing bars 110 and 111, the reinforcing bars 111 and the lower slab 170 adjacent to the inner wall body 180 are respectively connected to and fixed to the reinforcing bars 181 of the inner wall body 180 which are integrally poured.

In addition, the reinforcing bars close to the inner wall body 180 of the reinforcing bars (110, 111) formed in the CIP bulb 100 constituting the back-up reinforcement and the side wall 131 intersects with the reinforcing bars 181 of the inner wall 180 ( The connecting reinforcing bars 182 for connecting the strip reinforcing bars 120 and the reinforcing bars arranged in contact with the transverse reinforcing bars 111 are to be spaced apart from each other at equal intervals. This connection structure will be equally applied to the upper left and right sides of the underground road.

In addition, when reinforcing the reinforcing bars (143,143 ') when the upper slab (140,140') is covered with a covering, it is placed in the ground and placed thereafter. And the reinforcing bars 181 embedded in the inner wall 180 are connected to each other in a state where the coating is removed.

12 is shown in the construction sequence 1/3 as shown in the drawings, each of the upper slab (142,142 ', 141,141' / 152,151) reinforcing bar should be connected in a zigzag connection without connecting in one place.

That is, each of the reinforcing bars 141, 142/151, 152 to be embedded in one side and the central upper slab (140, 150) should be connected, and each of the reinforcing bars 141 ', which are embedded in the other side and the center upper slab (140', 150), 142 '/ 151,152 should be connected. At this time, as described above, it is important that each reinforcing bar is connected to each other and then placed in place.

13 is a detail shown in the 1/2 construction sequence of the upper slab (140, 140 ') reinforcing bar and the reinforcing bar in the CIP bulb 100 is to be coupled to the structural disadvantage due to the buoy as a connection in a certain tension portion Therefore, it is important to increase the cross-sectional thickness of the central upper slab to the outside to reduce the parenting.

To this end, the respective reinforcing bars 141, 141 '/ 142, 142' to be embedded in each upper slab (140, 140 ') should be fixed to the central reinforcing bars 132 of the CIP bulb 100, as shown in the center portion 130 Binding and fixing the position which is in contact with each upper slab (140,140 ') that is the upper side of the CIP bulb 100 forming a) and pours the upper slab 140 on one side. At this time, the reinforcing bars 141 and 142 of a certain length are arranged in a zigzag before being placed in order to connect with the reinforcing bars of the other upper slab, so that they are not connected only in one place, so that the other bars (141 'and 142) of the other upper slab 140' are not connected. Fix the end of ') with a coupler or gas pressure welding method. In this way, the upper slabs 140 and 140 'and the central portion 130 are firmly connected.

FIG. 14 illustrates an “E” portion in FIG. 8, and shows an example for fixing the corner reinforcement 160 to one side of the CIP bulb 100 in the enlarged view. As shown in the figure, the CIP bulb ( It is configured to connect the anchor bolt buried in 100 in advance so that the corner reinforcement 160 has a sufficient supporting force. This connection also applies to connections with upper slabs 140 and 140 '.

CIP Bulb Construction Process- S10

This process is a process for forming the side wall and the central wall or pillar corresponding to the wall of the position to build the underground driveway and is constructed in the same manner as in the first embodiment (illustrated in FIG. 1), so the detailed description will be made as follows. See.

One side  Upper Slab Construction Process- S20

When the installation of the CIP bulb 200 is completed through the above-described process (S10), the section of the road section as shown in FIG. 25 is separated, and in this state, the whole compartment is divided by the CIP bulb 200 in this state. It will be understood that either side of the third divided by the width source as a process for forming the upper slab first.

To this end, as shown in FIG. 26, the center portion of the upper half of the entire width source of the upper slab (as described above, the entire portion dividing the center of the wall made of CIP bulbs is named as the central portion, and this is denoted by 230 in the drawing). It also includes a pillar type formed by the bulb) (230) to excavate any one side of the road portion to remove the ascon layer and soil.

At this time, it is assumed that the concrete PC1 earth plate 204, which is applied in the fourth embodiment, is installed and installed as the H-pile soiling facility.

In this way, after the excavation work is carried out to a certain depth, the flooring concrete and formwork are installed on the excavation surface, and then the upper slab of the PC structure is installed.

At this time, the anchor bolt for connecting the corner reinforcing material 260 may be configured in advance. This is to facilitate the installation immediately when installing the corner reinforcement 260.

In the present invention, the upper structure of the PC structure slab as shown in Figures 26 to 28 are divided into three equally each of the total width source and sequentially equipped with the upper structure of the PC structure, for the purpose of understanding the embodiment of the present invention (Fig. 26) When viewed, the upper slab on the right side is named the upper slab of one side of the PC structure and denoted by reference numeral 240. The slab on the opposite side is named the upper slab of the other side of the PC structure and denoted by the reference numeral 240 'and the center slab is centered. The side PC structure was named upper slab and marked 250.

At this time, the reinforcing bar of one side PC structure upper slab 240 is arranged to be connected in a zigzag manner so as not to be connected at one place for connecting the reinforcement with the center side PC structure upper slab 250 which is in contact with the neighbor, and the one side PC structure upper slab 240 After the construction of), waterproofing material and protective mortar should be installed.

In this way, after the one side PC structure upper slab 240 is installed, the trench construction (S30) for installing the other side PC structure upper slab 240 ', which will be described later, is made so as not to disturb the flow of traffic before. One side of the PC structure upper slab 240 has to go through a cover process to cover the surface.

On the other hand, in the case of covering the soil to cover the zigzag reinforcement of the one side PC structure upper slab 240 and the other side PC structure upper slab 240 'while the soil covering facility to cover the first earthquake facility for the first Since construction is performed in the same manner as in the embodiment (illustrated in FIG. 17), the first embodiment will be described in detail.

On the other hand, in the construction of the one-side PC structure upper slab 240, unlike the above, it is possible to construct the trench construction method as the construction method of 1/2 divided into one side and the other side on the basis of the center by the circumstances of the road. have.

The other side  Upper Slab Construction Process- S30

This process, after pouring the one-side PC structure upper slab 240 by the above-described one side upper slab construction process (S20), and covers the upper surface of the one-side PC structure upper slab 240 so that the flow of traffic is not disturbed. When viewed from the other side, that is, the side facing the one side PC structure upper slab 240 (Fig. 27) refers to the process of dig construction to cast the upper upper slab (the other side PC structure upper slab-240 ').

In this way, the periphery of the periphery of the other PC structure upper slab 240 'is installed, and then the other side PC structure upper slab 240' as shown in FIG. The facility work of the PC structure upper slabs 240 and 240 'can be completed, and the method of covering the soil or installing the H-piling and digging and earth plate is the same as the method of the one side PC structure upper slab 240.

On the other hand, the reinforcing bars of the other PC structure upper slab 240 'allows the joints to be arranged in a zigzag manner so that the bars of the other PC structure upper slab 240 are connected to the neighboring PC structure upper slab 250 so as not to be connected at one place. After construction of 240 ', waterproofing material and protective mortar should be applied.

Center  Upper Slab Construction Process- S40

When the installation of the one side and the other upper slab construction process (S20, S30) is completed, as shown in Figure 28 to excavate the central side of the upper road portion to remove the ascon layer and soil.

As such, when digging the center side, an earth block facility in which the H pile 90 and the anchor body 91 of the first embodiment (FIG. 17) already installed during one side and the other upper slab construction process (S20, S30) are connected. Because of this, it is possible to dig without a separate earthen facility.

In this way, after proceeding the trench work in a certain depth, and then install the flooring concrete and formwork to the trench surface, and then install the upper slab 250 of the central PC structure. At this time, the reinforcing bar of the upper slab is already arranged in a zigzag state on one side and the other side, and the secondary concrete is poured. After pouring, the waterproofing material and the protective mortar are constructed.

After installing the central PC structure upper slab 250 as described above, the bolts for pulling the H-pile 90 which were installed in the construction of any one side and the other PC structure upper slab 240 and 240 'are backfilled. While drawing the H-pile 90.

On the other hand, in the case of 1/2 construction, the reinforcing bar should be made in the center part, so it may be a burden due to the parent's cement. This is to reduce the size of the parent.

Corner portion  Reinforcement and Earthanka  Construction Process- S50

This process, after completing the installation work of each of the above PC structure upper slab (240,240 '), the stiffening steel for corner reinforcement to induce a short interval between the PC structure upper slab 240,240' or the inner wall (280,280 ') The construction process for installing the ground anchors (260) and earth anchors are carried out in the same manner as in FIG. 29. In the CIP bulb construction process (S10), as in the first embodiment, an anchor bolt for installing the stiffener steel 260 is purchased in advance. Even when manufacturing the upper slab of the PC structure, the anchor bolts are manufactured in a state of purchase in advance to install only a certain interval of stiffener 260 by excavation of only a corner portion.

Since the interval between the upper slab and the CIP bulb 200 is shortened due to the installed sabot steel 260, the member force decreases, and thus the safety is further maintained, and the end surface and the final drilling surface of the sabor steel 260 in the inner wall 280 and 280 '. Earth anchors are used to reduce the length of the bridge. The facility of Earth Anca is advantageous in terms of economical ability to reduce the member force of the inner wall (280, 280 ') and to reduce the length of the entry.

On the other hand, as shown in Figure 30, when using the PC strand (123) to buy the tension in the CIP bulb 200, the same effect can be obtained even without the earth anchor can be applied by the person using the present invention selectively Will be taken for granted.

Reinforcement work of both lower slab and central wall or column- S60

The process flow of the present invention and each configuration according thereto will be described by dividing each process.

CIP  Bulb Construction Process- S10

This process is a construction process to install unit PC piles and unit PC square files and unit square piles and CIP bulbs of central wall or column. It is a process for forming pillars.

To this end, as shown in the drawing, the PC square pile wall 302 and the PC wall 300 'or PC such that walls or sidewalls are formed at the center portion and both side surface portions to separate the center within the region range for constructing the underground roadway, respectively. The square pile wall 301 is formed.

Here, the central portion may be formed as a wall using the PC square pile wall 302 or the CIP bulb 300, a column type, for example, to form a CIP bulb in the form of a column of the middle is broken bar, the site It can be varied depending on the conditions and design, it will be obvious that such a change can be selectively applied by those using the present invention.

The PC wall 300 'at both side portions is composed of unit PC walls 300'a. As shown in FIG. 48, a plurality of cast iron bars 310 and 311 are arranged in a rectangular shape to have a predetermined size. The reinforcing bars crossing the main reinforcing bars 310 and 311 are spaced at equal intervals and tied together with a stirrup. The main reinforcing bars and the reinforcing bars are combined into one and the concrete is poured and the unit PC wall 300'a is dried.

On the other hand, as shown in FIG. 48, the unit PC wall 300'a is dried with two protruding L-shaped steels 309 embedded in the connecting portion, and the adjacent unit PC wall 300'a has two embedded L in the connecting portion. It is configured to be connected to each other by being dried in a state in which the shaped steel and the iron plate 309 'are embedded.

The unit PC wall 300'a is coupled to the inside of the width source excavated with a suitable width by a large equipment such as D-Wall, and many of these unit PC walls 300'a are longitudinally (the starting point direction). When assembled in a columnar manner of the PC wall 300 is completed.

In addition, the PC square pile walls (301, 302) is also composed of the unit PC square pile walls (301a, 302a) bar as shown in Figures 56, 57 a plurality of cast steel bars (310,311) arranged in a square of a certain standard It is disposed and spaced apart the strip reinforcing bars 320 surrounding the main reinforcing bars (310,332) at equal intervals, the main reinforcing bar and the reinforcing bars are combined into one, the concrete is poured and curing unit PC square pile walls (301a, 302a) is dried, in Figure 48 As shown, it has the same connection structure as the unit PC wall 300'a.

The unit PC square pile walls 301a and 302a are introduced into a width source excavated with a proper width by augers such as SCW and DWM. Many of the unit PC square pile walls 301a and 302a are longitudinally When assembled in a columnar manner of the dot direction), the PC square pile walls (301, 302) is completed.

On the other hand, when drying the unit PC square pile wall (301a), on one side (referred to as the inner side where the wall is formed and referred to as one side side) of the reinforcement mesh, the dodak pattern formwork 322 and the chock 303 Be sure to tie it up to the bars.

This is to facilitate the interconnection of the reinforcing bars in the transverse direction of the inner walls 380 and 380 'and the reinforcing bars arranged after the band bars of the PC square pile wall 301.

In addition, two PC strands 323 are arranged in contact with the one side side stirrup reinforcing bar, but only a certain length of the unit PC square pile wall 301a. The role is to increase the load capacity of the unit PC square pile wall 301a so as to cope with the external action member force without installing the earth anchor 210 between the corner reinforcement installed on the outermost right side of the upper slab and the final digging line. As a structure to make it possible, it arrange | positions for every unit PC square pile wall body 301a.

On the other hand, the tensioning time of the PC strand 323 is settled in the upper slab at the time when the rebar assembly of the upper slab is completed, thereby acting to more tightly aggregate the upper slab and CIP, and also reduce the right angle parent You can reap.

On the other hand, since the PC square pile wall 302 in the center is not coupled to the inner wall (380, 380 '), unlike the PC square pile wall 301 at both sides as shown in Figure 57 and the Dodlock pattern formwork 322 Construct the unit PC square pile wall 302a cured and dried in the absence of the stool 303, and finally integrate tension by using a plurality of PC strands 324 in the longitudinal direction (the starting point direction). Make up the wall.

The unit walls 302a are embedded in a plurality of rows in a central wall or column (hereinafter collectively referred to as a central portion) in an area for forming an underground roadway, and the unit walls 300'a and 301a are moved to both left and right sides around the central portion thereof. They are embedded in a plurality of rows with a predetermined distance vertically spaced in the basement at a distance from each other to form side walls and a central portion. These unit walls 302a, 300'a, 301a are subject to constraints that are only possible in soil layers and impossible in rock sections. This is because the equipment that excavates the ground cannot penetrate the rock. In this case, unit walls 301a and 302a are formed by using T4 equipment that can be perforated to the rock side every 2.0m to 2,5m, and between the soil layers only. After forming the unit walls 302a, 300'a, 301a, construct the upper slab 340.350 and excavate it to the rock section to install the supporting anchors of the unit walls 302a, 300'a, 301a and continue the internal excavation. Cut the rock from the bottom of the unit walls (302a, 300'a, 301a) installed only to the soil layer to the bottom of the lower slab cast concrete to carry out the reinforcing bars of the unit walls (302a, 300'a, 301a) and mix the concrete with water repellent. When poured, solid inner walls 380 and 380 'are formed.

On the other hand, the top height of the unit walls (302a, 300'a, 301a) may be different depending on the height of the excavation height, in order to solve this unit wall (302a, 300'a, 301a) and the hanging wall 305 In the combined state, they are to be aligned and introduced inside the width source excavated with trenches and augers.

The hanging wall 305 is made of PC as a concrete product and is combined with the hanging reinforcing bar 312. The H-shaped steel 313 for mounting on the top is placed horizontally and placed in the guide steel 314 and the upper slab ( 340, 350, 340 'and the wall 302, 300, 301 is to be separated when connecting.

Meanwhile, the unit walls 300'a, 301a and the hanging wall 305 are combined to fill the voids by filling back the outside of the excavated width source after completion of the input into the excavated width source with the trench and auger equipment.

As such, the unit walls 300'a and 301a and their connection gaps are indexed using the index plate 306, and the outer surfaces of each of the unit walls 300'a and 301a are previously applied with a liquid waterproofing agent in preparation for harmful substances. Take measures to prevent corrosion.

Fourth Example

In the fourth embodiment according to the present invention, as shown in Figure 4, the pile construction step (S10-1), the center side upper slab construction step (S40) for driving the thumb pile and the middle side both sides piles on both side walls, One side upper slab construction process (S20), the other side upper slab construction process (S30), internal excavation and earth anchor construction process (S50-2), both side lower slab and central wall or column reinforcement construction process (S60), The construction of the underground roadway is performed by both inner wall construction steps (S70) and the finishing construction step (S80).

Hereinafter, the process flow of the fourth embodiment according to the present invention and the respective constitution according to the process will be described.

Pile Construction Process- S10 -One

This process is a process for forming the thumb pile 401 on both sides of the middle pile 400 and the structural sidewalls on both sides corresponding to the central portion of the position to build the underground driveway.

To this end, as shown in the drawings, the middle pile 400 and the thumb pile 401 are respectively formed on the left and right sides and both side wall portions of the central portion for separating the center within the region range for constructing the underground roadway.

The middle pile 400 at the left and right sides of the center portion is installed at intervals of 4.0 m, and the thumb piles 401 at both side wall portions of the structure are disposed at intervals of 2.0 m. The trench of the middle pile 400 is relatively shallow in height at the top of the earth pressure, so that even when installed at intervals of 4.0 m, it can support the earth pressure sufficiently, whereas the thumb pile 401 has a large and relatively large distance of unsupported during internal excavation. Earth pressure will work, so it was installed at 2.0m intervals.

On the other hand, the method using the middle and the thumb pile is possible not only in the soil layer but also in the rock section.

The pile is drilled using T4 equipment that can be drilled to the rock side, and the earth plate is attached to the soil layer during internal excavation, and after that, the arm is cut off to fill the earth plate and the backfilling soil to form the earth wall. You can do

Center  Upper Slab Construction Process- S40

When the installation of the intermediate pile 400 and the thumb pile 401 is completed through the above-described pile construction process (S10-1), as shown in FIG. To me.

As such, when digging between the middle pile 400, the earth plate should be installed in the middle pile. In consideration of the safety due to length, the concrete PC1 earth plate 404 of FIG. 76 was manufactured and installed, and the gap of the thumb pile was 2.0. Considering m is dualized to use the concrete PC2 earth plate 410 of Figure 77.

After proceeding the trench work in a certain depth in this way, after installing the floor-level concrete and formwork to the trench surface, the upper side slab 430 is installed. At this time, the reinforcing bar of the upper slab can be arranged in a zigzag so as to be connected in a zigzag so that the reinforcing bar is connected to the central upper slab 430 in contact with the neighbor, and after the construction of the central upper slab 430, the waterproof material and the protective mortar Construct it.

After placing the central upper slab 430 as described above, a trench construction (S30) for placing one side and the other upper upper slab 440, 450 is made. The surface of the slab 430 must be covered with a cover process.

In the cover process, the soil is covered with a separate clogging facility. As shown in FIG. 70, as a separate clogging facility, a plurality of perforation holes 92 are made in one flange of the H pile 90, and a predetermined distance is retracted backward from the joint part. The facility is installed in a manner that combines reinforcing bars with bolts 93 at the location of the drilling holes 92, and then stacks them to the ground in the same way.

In this way, when one side and the other upper slab 440, 450 is destroyed, a separate mudstone facility installed during the construction of the central upper slab 430 performs the role of the earth wall, so that one side and the other upper slab ( 450 is easy to break.

One side  Upper Slab Construction Process- S20

In the present invention, the upper slab is divided into both sides with respect to the center upper slab 430 as shown in FIGS. 66 to 68, respectively, and is subjected to a sequential pouring process. When viewed, the upper slab on the right side is named one upper slab and denoted by reference numeral 440, and the slab on the opposite side is named the other upper slab and denoted by reference numeral 450.

When the installation of the central upper slab 430 is completed through the above-described process (S20), the section of the road section as shown in FIG. 65 is separated, and in this state, the central upper slab 430 is separated by the middle upper slab 430. It will be understood as a process for first forming either side on the basis of the upper slab to be partitioned.

On the other hand, when digging one side upper slab 440, there is a dirt block that was buried in advance when covering the central upper slab 430, there will be no difficulty in the digging, it can be completed by having only a brace, but in the case of covering the bolt (93) should be backfilled while releasing and the H pile 90 is pulled out when the backfill ends.

Afterwards, the PC strand wire 402 buried in the thumb pile is tensioned so as to correspond to the member force acting between the one upper slab 440 and the earth anchor installed during the internal excavation.

On the other hand, before the construction of one side upper slab 440 should be installed concrete PC2 earth plate 410 that extends to the thumb pile flange. As shown in FIG. 77, the concrete PC2 earth plate 410 is configured to wrap the thumb pile 401 flange with a rotating iron plate 409 so as not to fall off, and the thumb pile 401 that touches it in order to facilitate future drawing. There was a slight play.

In addition, the support of one side of the upper slab 440 on one side, as shown in Figure 75 by hooking the PC wire 408 to the anchor in the one upper slab 440 through the drill hole of one flange of the thumb pile 401, thumb thumb 401 ) To settle on top.

Meanwhile, when constructing the secondary inner wall, the PC wire 408 anchored to one side and the other upper slab 440, 450 should be dismantled, and a brace supporting one side and the other upper slab 440, 450 is installed on the primary inner wall. After the PC wire 408 is cut off, it can be formed by installing a sheet waterproofing material and pouring a secondary inner wall body.

In addition, when constructing the upper slab, it is possible to apply the PC structure slab as in the second embodiment or the Half PC structure slab as in the fifth embodiment.

It is natural that the user can selectively apply it because the quality is improved and rapid construction is possible.

At this time, the joint of the reinforcing bar is as shown in FIG. 71 and the joint of the main reinforcing bar is as shown in FIG.

The other side  Upper Slab Construction Process- S30

This step is to cast the one side upper slab 440 by the one side upper slab construction process (S30), and then cover the upper surface of one side upper slab 440 so that the flow of traffic is not obstructed, and then the other side, one side It refers to a process of carrying out the trench for pouring the upper slab (the other upper upper slab-450) of the left side when viewed from the side facing the upper slab 440 (FIG. 67).

In this way, the periphery of the periphery was carried out to pour the other upper upper slab 450, and then the upper upper slabs 450 and 450 to the upper side for constructing the underground driveway by curing the other upper upper slab 450 as shown in FIG. It is possible to complete the pouring work, and the process of covering or digging construction method is the same as the method of one side upper slab 440, and afterwards, the tension of the PC strand wire 402 buried in the thumb pile is settled on the other side upper slab ( Corresponding to the member force acting between the 450 and the earth anchor installed during the internal drilling is the same as the other upper slab construction process (S30) according to the previous embodiment.

CIP Bulb Construction Process- S10

This process is a process for forming the side wall and the central portion corresponding to the wall of the position to build the underground driveway.

To this end, as shown in the drawing, the CIP bulb 600 is formed at the center and both side surfaces within the region for constituting the underground driveway, but the central part is formed up to the upper end of the central haunch, and the wall, that is, the side wall is formed up to the surface at both sides. .

The cast-in-place (CIP) bulb 600 has a plurality of cast bars 610 and 611 arranged in a rectangular shape as shown in FIG. 105, and spaced apart at intervals between the strip bars 120 surrounding the cast bars 610 and 611. Reinforcing wire mesh is formed by combining main reinforcing bars and band reinforcing bars.

By forming a tube (hereinafter referred to as a casing) that surrounds the outermost part of the reinforcing wire mesh, and then curing by pouring concrete therein, it is possible to form a cylindrical CIP bulb 600 consisting of a single unit, and Otherwise, after drilling the hole for the CIP bulb 600 is inserted, the reinforcement mesh is inserted into the hole, and then the concrete is poured to cure the finished CIP bulb 600.

On the other hand, the gap between the two sides of the CIP bulb 600 formed in advance between the CIP bulb 600 and the CIP bulb 600 formed at regular intervals are punched while forming a new new CIP bulb 115 of the same type. CIP bulb 600 and the new CIP bulb 615 to overlap each other. In addition, the formation process of the new CIP bulb 615 is the same as the CIP bulb 600.

In the drawings, reference numeral 631 denotes a sidewall formed by the CIP bulb 600 and the new CIP bulb 615. In the present invention, the CIP bulb 600 is a unit formed by the CIP bulb 600 and the new CIP bulb 615. ), And are embedded in a line by the CIP bulb 600, and the side walls on both sides of the basement are separated and denoted by reference numerals.

In addition, when forming the CIP bulb 600 constituting the wall, that is, the side wall at both side portions, the panel 602 such as plywood is provided on one side of the reinforcing mesh (hereinafter referred to as the one side). In order to be tied to the band reinforcement to prevent the concrete from being placed inside the panel 602, such as plywood when placing concrete, the band 603 is partially disposed inside the band reinforcing bar.

This is to facilitate the interconnection of the reinforcing bars in the transverse direction of the inner wall reinforcement (681) and the reinforcing bars arranged after the band reinforcing bars of the CIP bulb (600).

In addition, two PC strands are arranged in contact with the main reinforcing bars on one side corner of the reinforcing wire mesh, but only in a certain length of the CIP bulb 600.

Here, the role of two PC strands 623 in contact with the main reinforcing bars on one side corner of the reinforcing wire mesh does not need to install an earth anchor between the position where the PSC beam installed with the first anchor earth anchor is mounted and the final digging line. The CIP bulb 600 is disposed in every CIP bulb 600 as a structure for enhancing the load capacity of the CIP bulb 600 to cope with an external action member force.

The CIP bulb 600 serves as a support pile or a buoyancy prevention pile, and as a structure for increasing friction, a frictional resistance increasing device having a predetermined interval is disposed only at the bottom of each CIP bulb 100 as in the first embodiment. Construct by the method.

The buoyancy prevention or support friction resistance increase method is shown in Figs. 106 and 107 in the first embodiment, both of which are at least as long as the role of the CIP bulb 600 at regular intervals as both side walls or the central portion. The construction should be to be formed at this time is to apply this method to the lower end of the CIP bulb 600.

First, in FIG. 106, two frictional resistance steel bars 104 are inserted into the rubber sleeve 105, bent in a “ V” shape, crossed and bundled in the “+” direction, and then a plurality of longitudinal intervals are placed at a constant position at the bottom of the CIP bulb 100. It is placed on the band reinforcement 120 while maintaining the PC steel wire 106 in the center while placing the concrete to form the CIP bulb 100 to a certain height while lifting the casing before the concrete is cured When the PC steel wire 106 is pulled out, both of the frictional resistance steel bars 104 inserted into the rubber sleeve 105 are rotated in a clockwise and counterclockwise direction to be unfolded in a “-” shape from a “ V ” shape. Since the friction-resistant reinforcing bar 104 is protruded from the CIP bulb 100, it acts as an anchor and a support pile to prevent the rise of the structure during buoyancy.

In Fig. 107, four frictional resistance bars 604 are inserted into the rubber sleeve 605 to form a wing reinforcement 607 in the shape of both wings in a “ V ” shape, crossed and tied in the direction of “+”, and then CIP bulbs ( 600) It is placed on the band reinforcement 620 while maintaining a plurality of longitudinal intervals at a constant position of the lower end, in which the concrete to form the CIP bulb 600 in a state where the PC steel wire 606 is placed at a certain height If you pull out the PC steel wire while lifting the casing before the concrete is cured, the frictional resistance bars 604 of both sides of the rubber sleeve 605 change from “ V ” shape to “-” shape. It is pushed in the horizontal direction to protrude. As the cured and expanded wing reinforcement 607 protrudes from the CIP bulb 600, it acts as an anchor body to prevent the rise of the structure during buoyancy and the reverse of the support pile. A it is.

As a method for increasing the bearing capacity, a method of forming a CIP bulb 600 at a predetermined interval or longer as a role length as a side wall or a central portion should be performed in the same manner as above, and at this time, a method of increasing frictional resistance at the lower end of the CIP bulb 600 is employed. To apply.

Such CIP bulb 600 is embedded in a plurality of rows while forming a side wall at a predetermined distance vertically in the basement at the distance of each spaced left and right sides around the underground roadway.

However, these CIP bulbs 600 are subject to constraints that are only possible in soil layers and impossible in rock sections.

This is because the auger's equipment that excavates the ground can't puncture the rock. In this case, the bulb 600 is formed during internal excavation using T4 equipment that can be drilled to the rock side every 2.0m. (600) and then excavated internally to the rock section to equip the CIP support anchor (608) and continue the internal excavation, but cut the rock from the lower end of the lower slab cast concrete (“A”) to the bottom of the CIP bulb equipped only to the soil layer. When the CIP reinforcement is continued and the concrete mixed with the powder waterproofing agent is poured, a solid inner wall (680, 680 ') is formed.

Internal excavation and Earthanka  Construction Process- S50 -2

In this process, after completing the above-described process of each CIP bulb 600, a single-level ground anchor is installed on the head of the CIP bulb 600 (that is, the portion where the PSC beam is mounted) to stabilize the sidewall 631. It is to plan.

Afterwards, the internal excavation is continued to reach the final excavation line. At this time, the PC strand wire 623, which was tension-fixed in the CIP bulb 600 forming process, supports the member force acting on the side wall 631, thereby achieving stability.

Both Side Slab Construction Process- S60 -One

This process is a process for forming the underground roadway by constructing the lower slab (670,670 ') after the above-described internal drilling and earth anchor construction process (S50-2) is completed.

After forming the discarded concrete and the outer sheet waterproof layer in the excavated space on both sides, the lower slab (670,670 ') is poured into the side wall 631 and the bottom of the excavated portion.

Here, the lower slab (670,670 ') refers to the pour body to be poured on the bottom surface of the underground driveway, as shown in the drawing, and pours to the haunting portion in contact with the inner side of the side wall (161).

After excavation and construction of the space on both sides as described above it is possible to construct a completed underground roadway when the casting process of the lower slab (670,670 ') is completed.

On the other hand, as shown in Figure 101, the lower slab (670,670 ') can be omitted in this process, in this case, the depth of CIP intrusion in the S10 process should ensure the appropriate length and permanently requires the earth anchor facility in the S50-2 process can do.

Both sides Inner wall  Construction Process- S70

Some of the inner walls 680 and 680 ', which are integrally vertically connected to both sides of the lower slab and poured into the side walls 631, are constructed in succession to the lower slabs 670 and 670', and the remaining inner walls 680 'are partially formed. After the inner wall (680,680 ') is cured, it is constructed while removing the earth anchor.

The inner wall bodies 680 and 680 'formed as described above are embedded in the CIP bulb 600 constituting the sidewalls 631 and the reinforcement bars intersected with the reinforcing bars 681 embedded in the inner wall bodies 680 and 680' so as to secure their rigidity. Among the reinforcing bars 610 and 611, the connecting bars 682 for connecting the reinforcing bars arranged in contact with the strip reinforcing bars 620 in the transverse direction to the reinforcing bars 611 adjacent to the inner wall body 680 are spaced up and down, respectively. It should be spaced apart.

PSC Beam Mounting and Upper Slab Construction Process- S230

When the installation of the inner wall (680,680 ') is completed through the above-described process (S70), the PSC beam 650 is mounted, and the reinforcement 681 and the CIP bulb (100) purchased when the inner wall (680,680') is constructed. Among the reinforcing bars 110 and 111 embedded in the reinforcing bar 111 close to the inner wall 680 and 680 ′, the reinforcing bar 111 penetrates the PVC pipe 651 pre-configured inside the PSC beam 650 and is disposed on the upper slab 640. The paper was connected to another bar (641, 642).

In this way, the PSC beam mounting process after the inner wall construction process (S70) on both sides is to reduce the risk of beam conduction, etc., which can occur because the subsequent process is long after the PSC beam mounting and to have a more stable construction process.

In addition, the reinforcing bar (110) arranged in the outer side of the reinforcing bars (110, 111) to be purchased in the CIP bulb 100 is to be connected and fixed to another reinforcing bar (642) disposed on the upper slab 640, In addition, since the upper sidewall 131 is fixedly connected to the upper side wall, the PSC beam 650 is permanently fixed so that no distortion or displacement occurs due to an external working load.

Meanwhile, the PSC beam 650 embeds a PVC pipe 651 through which the reinforcement 681 of the inner wall body 680 penetrates at the end and fabricates the end-stage reinforcement at the end so as to be fixedly connected to the side wall 131. ), And the PC strand 653 was placed on top of the edge of the PSC beam 650 so as to reduce the right parent portion.

The tension fixing of the PC strands 653 installed in the PSC beam 650 is caused by the inequality of the inner wall 680,680 'and the difference between the rigidity of the PSC beam 650 and the inner wall 680,680'. This is to prevent the transmission of the structural strength which is disadvantageous to).

In addition, since the PC strand 123 buried in the CIP bulb 100 and tension-fixed on the upper part of the CIP bulb 100 penetrates the PVC pipe 651 pre-configured inside the PSC beam 650, it re-tensions and stabilizes. The stiffness difference mentioned above can be reduced, and the effect of reducing the parent moment can be reduced, which has the advantage of increasing the load capacity in the entire structure and can reduce the defects or maintenance costs that may occur in the future.

On the other hand, the interval between the PSC beam 650 has a horizontal beam 654 to prevent lateral displacement and to allow the PSC beam 650 group to act integrally, and the edge of the PSC beam 650 group is the rear slab ( 660) to prevent the introduction of rear soil and to form a waterproof layer.

In addition, in the present invention, the upper slab is to play a structural role to facilitate the transverse transmission of the member force with the cross beam 654, so as to connect between the PSC beams 650 to each other. In addition, to prevent the inflow of external soil and to form a waterproof layer.

As such, after placing the upper slab 640 and the rear slab 660, the surface must be covered with a cover process.

Finishing Construction Process- S80

When the process (S230) as described above is completed, ascon is installed on the completed cover of the cover to pass the vehicle, and to complete the process of the underground driveway by installing the sidewalk and electric facilities, tiles and ascon inside the underground driveway.

In the construction of the underground roadway using the CIP bulb 600 through a series of processes as described above, FIG. 102 illustrates the connection fixing of the reinforcing bars 671 and 672 of the side walls 631 and the lower slabs 670 and 670 '. It shows the state which becomes.

The bottom slab 670, 670 'and the lower sidewall 631 are connected to each other so that the bottom slab 670 and 670' are connected to the strip reinforcing bar 620 of the rebar 611 exposed by the part to be cut. The same will be applied to the lower left and right side of the.

FIG. 103 illustrates a state in which the lower slabs 670 and 670 'are connected to the central portion 630, and a plurality of horizontal holes 601 are formed in the horizontal direction, and the horizontal slabs 601 are formed in the lower slab 670. Passed reinforcing bars (671,672) is shown connected to the other reinforcing bars (671 ', 672') to be buried in the lower slab (670 ') of the other side, and the stirrup reinforcement (673) connected to the haunch is arranged Doing.

The fixed state between the walls 680 and 680 'is shown.

On the other hand, the PSC beam is placed on the side walls 631 and the inner walls 680 and 680 ', wherein the reinforcing bars 611 and inner wall reinforcement 681 close to the inner wall of the reinforcing bars 610 and 611 constituting the side walls 631 are PSC beams. Through the PVC pipe that is pre-buried in the upper slab 640, the reinforcing bar (641, 642) and the upper slab 640, the reinforcement (642) is fixed to the reinforcing bar 610 of the side wall (631) PSC beam It restrains it from moving, and adds restraint reinforcing bar 644 protruding from the PSC beam end.

105 is one side of the CIP bulb 600 constituting the side wall 631 in order to be connected to the outside of the inner wall (680, 680 ′) by the connecting reinforcing bar 682 as shown in the figure The band reinforcing bars 620 surrounding the reinforcing bars 610 and 611 to be embedded in the CIP bulb 600 should be finished by a panel 602 such as plywood so as to be exposed to the outside by a pre-installed band 603 or the like.

In order to be constructed as described above, it is preferable to form the panel 602 so that one side is cut to form the CIP bulb 600 for forming the sidewall 631 in the sidewall CIP bulb construction process (S10).

The side wall 631, which is obtained by the panel 602 as described above, is provided with a band reinforcing bar 620, which wraps the reinforcing bars 610 and 611 embedded in the CIP bulb 600 constituting the side wall 631. The reinforcing bars of the inner wall bodies 680 and 680 'are disposed by connecting reinforcing bars in a state exposed to the outside by the 603 and the like, and connecting bars 682 for connecting the reinforcing bars and the band bars in the above-described horizontal direction. It can be connected to the reinforcing bars intersected with (681).

I would like to suggest a method for construction.

The process flow of the present invention and each configuration according thereto will be described by dividing each process.

CIP Bulb Construction Process- S10

This process is a process for forming the side wall and the central portion corresponding to the wall of the position to build the underground driveway.

To this end, as shown in the drawing, CIP bulbs 700 are respectively formed in the center and both side surfaces within the region for constituting the underground road, but the central part is formed up to the upper end of the central haunch and the walls, ie, side walls, are formed on both sides. .

As described above, the cast-in-place (CIP) bulb 700 has a plurality of main reinforcing bars 710 and 711 arranged in a rectangular shape as shown in FIG. 116, and spaced apart at intervals between the strip reinforcing bars 720 surrounding the main reinforcing bars 710 and 711. Reinforcing wire mesh is formed by combining main reinforcing bars and band reinforcing bars.

By forming a tube (hereinafter referred to as a casing) that surrounds the outermost part of the reinforcing wire mesh, and then curing by pouring concrete therein, it is possible to form a cylindrical CIP bulb 700 consisting of a single unit, and Otherwise, after drilling the hole for the CIP bulb 700 is inserted, the reinforcement mesh is inserted into the hole, and then the concrete is poured to cure the finished CIP bulb 700.

On the other hand, the gap between the CIP bulb 700 and the CIP bulb 700 formed between the gaps formed in the gap between the pre-formed CIP bulb 700 is formed by forming a new CIP bulb 715 of the same type. CIP bulb 700 and the new CIP bulb 715 to overlap each other. In addition, the formation process of the new CIP bulb 715 is the same as the CIP bulb 700.

In the drawing, reference numeral 731 denotes a side wall formed by the CIP bulb 700 and the new CIP bulb 715, and reference numeral 730 also denotes a central wall or column formed by the CIP bulb 700 and the new CIP bulb 715. In the present invention, the unit formed by the CIP bulb 700 and the new CIP bulb 715 is referred to as a CIP bulb 700, and is embedded in a row by the CIP bulb 700 to form sidewalls on both sides of the basement. Are separated by reference numerals.

In addition, when forming a CIP bulb 700 forming a wall, that is, a side wall at both side portions, a panel 702 such as plywood is provided on one side (referred to as an inner side where a wall is formed and hereinafter referred to as one side) of the reinforcing wire mesh. In order to be tied to the band reinforcement to prevent the concrete from being poured inside the panel 702 such as plywood when placing the concrete, the band 703 is partially disposed inside the band reinforcing bar.

This is to facilitate the interconnection of the reinforcing bars in the transverse direction of the inner wall reinforcing bars 781 and the reinforcing bars arranged after the strip reinforcing bars of the CIP bulb 700.

In addition, two PC strands are arranged in contact with the main reinforcing bars on both sides of the reinforcing wire mesh one side corner, but only a certain length of the CIP bulb 700.

Here, the role of the two PC strands 723 in contact with the main reinforcing bars on one side corner of the reinforcing wire mesh is to cope with the absence of external action without installing the earth anchor between the position of the first anchor earth and the final digging line. It is arranged in every CIP bulb 700 as a structure for enhancing the load capacity of the CIP bulb 700 to be able to.

The CIP bulb 700 also serves as a support pile or a buoyancy prevention pile, and a structure for increasing frictional force is disposed at a lower end of the CIP bulb 700 at a predetermined interval, as in the first embodiment. Construct by the method.

As to the buoyancy preventing or supporting friction resistance increasing method, two methods are shown in Figs. 117 and 118 in the seventh embodiment, all of which have a predetermined interval between the CIP bulbs 700 serving as both sides of the wall or the central part. The construction should be to be formed at this time is to apply this method to the lower end of the CIP bulb (100).

First, in FIG. 117, two frictional resistance bars 704 are inserted into the rubber sleeve 705, bent in a “ V ” shape, crossed and tied in a crisscross (+) direction, and then a plurality of reinforcement bars in a fixed position at the bottom of the CIP bulb 700 are first placed. Maintain the longitudinal spacing and is placed on the band reinforcement (720) at this time, while placing the PC steel wire (706) in the center of the concrete to form a CIP bulb 700 to a certain height while placing the casing before curing When pulling up the PC steel wire 706, the frictional resistance bars 704 of both sides of the rubber sleeve 705 are rotated clockwise and counterclockwise to unfold in a “-” shape in a “ V” shape. Cured friction-resistant reinforcing bar 704 is protruded from the CIP bulb 700, and thus serves as an anchor and a support pile to prevent the rise of the structure during buoyancy action.

In FIG. 118, four frictional resistance bars 704 are inserted into the rubber sleeve 705 to form a wing reinforcement 707 in the shape of both wings in a “ V ” shape, intersect and tie in the “+” direction, and then CIP bulbs ( 700) A plurality of longitudinal intervals are maintained at a predetermined position at the lower end and are disposed on the band reinforcement 720. At this time, the concrete for forming the CIP bulb 700 is placed at a predetermined height with the PC steel wire 706 disposed at the center. If you pull out the PC steel wire while lifting the casing before the concrete is cured, the frictional resistance bars 704 of both sides of the rubber sleeve 705 change from “ V ” shape to “-” shape. It is pushed in the horizontal direction to protrude, so the cured wing reinforcement 707 protrudes from the CIP bulb 700, thus acting as an anchor body to prevent the rise of the structure during buoyancy and the reverse of the support pile. A it is.

As a method for increasing the bearing capacity, a method of forming a CIP bulb 700 at a predetermined interval or longer as a role length as a side wall or a central portion should be performed in the same manner as above, and at this time, a method of increasing frictional resistance at the lower end of the CIP bulb 700 is employed. To apply.

Such CIP bulb 100 is embedded in a plurality of rows while forming a side wall at a distance vertically spaced in the basement at a distance from each other to the left and right sides around the underground road. This method is also constructed in the same manner as in the sixth embodiment.

However, these CIP bulbs 700 are subject to constraints that are only possible in soil layers and impossible in rock sections. This is because the auger's equipment that excavates the ground is not able to puncture the rock. In this case, CIP bulb 700 is formed with internal excavation using T4 equipment that can be drilled to the rock side every 2.0m. CIP bulb 700 is formed and then excavated to the rock section to equip the CIP support anchor 708 and continue the internal excavation, but the rock is cut from the bottom of the lower slab cast concrete to the soil layer (“A”). If you continue the CIP reinforcement and cast concrete mixed with powder waterproofing agent, a solid inner wall (780, 780 ') is formed.

Internal excavation and Earthanka  Construction Process- S50 -2

The present step is to stabilize the side wall 131 by installing a single earth anchor on the head of the CIP bulb 700 after completing the process of each CIP bulb 700 described above.

After the internal excavation continues to reach the final excavation line at this time, since the PC strand wire 723 that was tension-fixed in the CIP bulb 700 forming process supports the member force acting on the side wall 731 is stable.

Both Side Slab Construction Process- S60 -One

This process is a process for forming the underground roadway by constructing the lower slab (770,770 ') after the above-described internal excavation and earth anchor construction process (S50-2) is completed.

Here, the lower slab 770, 770 'means a pour body that is placed on the bottom surface of the underground driveway, as shown in the drawing, and pours up to the haunting portion in contact with the inner side of the side wall 731.

After excavation and construction of the space on both sides as described above, when the pouring process of the lower slab (770,770 ') is completed, it is possible to construct a completed underground roadway.

Meanwhile, as shown in FIG. 113, the lower slab (770,770 ') can be omitted in this process. In this case, the depth of CIP incorporation in the S10 process must be secured and the earth anchor facility in the S50-2 process is permanently required. can do.

Both sides Inner wall  Construction Process- S70

Some of the inner walls 780, 780 ', which are integrally vertically connected to both sides of the lower slab and poured into the side walls 731, are constructed in succession to the lower slabs 770, 770' and the remaining inner walls 780 'are part of the above. After the inner wall (680,680 ') is cured, it is constructed while removing the earth anchor.

The inner walls 780 and 780 'formed as described above are embedded in the CIP bulb 700 forming the sidewalls 731 and the reinforcing bars that are intersected with the reinforcing bars 781 embedded in the inner walls 780 and 780' to secure their rigidity. Among the reinforcing bars 710 and 711, a plurality of connecting bars 782 for connecting the reinforcing bars arranged in contact with the band reinforcing bars 720 in the horizontal direction to the reinforcing bars 711 adjacent to the inner wall bodies 780 and 780 ', respectively. It should be provided at intervals apart.

Finishing Construction Process- S80

As described above, when the inner wall construction process (S70) on both sides is completed, the process of the underground roadway is completed by installing a sidewalk and an electric facility, a tile and an ascon inside the underground roadway.

In the construction of the underground roadway using the CIP bulb 700 through a series of processes as described above, FIG. 114 shows a state in which the side walls 731 and the respective bars 771 and 772 of the lower slab 770 and 770 'are connected and fixed. It is shown.

As shown in the drawing, a portion of the reinforcing bars of the inner reinforcing bar 781 of the inner wall body contacting the inner wall 780,780 'among the reinforcing bars 710 and 711 that are embedded in the respective CIP bulbs 700 forming the side wall 731. The bottom slab 770, 770 'and the lower side of the side wall 731 are connected to be fixed to the strip reinforcement 720 of the reinforcing bar 711 exposed by the part to be cut by), such a connection structure is an underground road The same will be applied to the lower left and right side of the.

8th Example  -

As the present invention according to Figure 119,

CIP bulb construction process (S10) forming both sidewalls and central wall or column, one upper slab construction process (S20), the other upper slab construction process (S30), the central side upper slab construction process (S40), and the corner Sub-reinforcement and earth anchor construction process (S50), both inner wall foundation and central wall or column construction process (S60-2), both inner wall construction process (S70) and finishing construction process (S80) Construction is done.

The process flow of the present invention and each configuration according thereto will be described by dividing each process.

Forming both sidewalls and central walls or columns CIP Bulb Construction Process- S10

This process is a process for forming the side wall and the central wall or pillar corresponding to the wall of the position to build the underground driveway.

To this end, as shown in the drawing, the CIP bulb 800 is formed such that a wall, ie, a side wall, is formed in each of a central part and both side surfaces for separating the center within an area range for constructing an underground roadway.

Here, the central wall may be formed as a wall using a CIP bulb, a column type, for example, a CIP bulb may be formed in a column type in which an intermediate middle is cut off, and may be varied according to site conditions and designs. It will be appreciated that such changes can be selectively applied by those using the present invention.

As shown in FIG. 136, the cast-in-place (800) CIP (800) has a plurality of main reinforcing bars 810 and 811 arranged in a rectangular shape and spaced apart at intervals between the strip reinforcing bars 820 surrounding the main reinforcing bars 810 and 811. Reinforcing wire mesh is formed by combining main reinforcing bars and band reinforcing bars.

By forming a tube (hereinafter referred to as a casing) that surrounds the outermost part of the reinforcing wire mesh, and then curing by pouring concrete therein, it is possible to form a cylindrical CIP bulb 800 consisting of a single unit, and Otherwise, after drilling the hole for the CIP bulb 800 is inserted, the reinforcing wire mesh is inserted into the hole, and then the concrete is poured to cure the finished CIP bulb 800.

The CIP bulb 800 and the CIP bulb 800 formed at regular intervals are then drilled by changing both sides of the pre-formed CIP bulb 800 between the CIP bulbs 800 to form a new CIP bulb 815 of the same type. 800 and the new CIP bulb 815 to overlap each other. In addition, the formation process of the new CIP bulb 815 is the same as the CIP bulb 800.

In the drawing, reference numeral 831 denotes a side wall formed by the CIP bulb 800 and the new CIP bulb 815, and reference numeral 830 also denotes a central wall or column formed by the CIP bulb 800 and the new CIP bulb 815. In the present invention, the unit consisting of the CIP bulb 800 and the new CIP bulb 815 is referred to as CIP bulb 800, and is embedded in a row by the CIP bulb 800 and is located in the center of the basement. The sidewalls on both sides are divided and denoted by reference numerals.

On the other hand, when forming the CIP bulb 800, one side of the reinforcing mesh (referring to the inner side where the wall is formed and referred to as one side). The panel 802, such as plywood, is bound to the band reinforcement concrete When pouring, concrete should not be placed inside the panel 802 such as plywood, and a chock 803 is partially disposed inside the band reinforcing bar, which is a horizontal reinforcing bar of the inner wall reinforcement 881 and a CIP bulb. This is to facilitate the interconnection of the reinforcing bars arranged after the band reinforcing bars of (800).

In addition, it is good to configure the anchor bolt for connecting the corner reinforcement 860 in advance. This is to facilitate the installation immediately when installing the corner reinforcement.

In addition, the panel 802 such as plywood is tied to the band reinforcement on both sides (right and left sides of which the center part is formed) of the reinforcing wire mesh so that concrete is not placed inside the panel 802 such as plywood when placing concrete. It should be, but the chord 803 is partially disposed inside the band reinforcing bar.

This is because the central CIP bulbs 800 are overlapping joints but do not lead to reinforcing bars, so that the reinforced bars and the band reinforcing bars are bundled to form an integral structure.

In addition, in the inner wall (880,880 '), two PC strands 823 are disposed in contact with the main reinforcing bars on one side corner of the reinforcing wire mesh, but only in a certain length of the CIP bulb 800, and in the center of the strip reinforcing bar 820 in the central part 830. The two PC strands 823 are arranged only in a certain length of the CIP bulb 800.

Here, the role of the two PC strands 823 in contact with the reinforcing rods on one side corner of the reinforcing wire mesh is that the external reinforcing member does not need to install an earth anchor between the corner reinforcement provided on the outermost right side of the upper slab and the final digging line. As a structure for enhancing the load capacity of the CIP bulb 800 so as to cope with it, it is arranged every CIP bulb (800), the two strands of PC strands 823 in the center of the CIP bulb thinned by the left and right sides of the Dodlock-shaped formwork ( This is to prevent the 800 from buckling due to external force.

On the other hand, the tensioning time of the PC strand is settled in the upper slab when the rebar assembly of the upper slab is completed, thus acting as a more tightly cohesion between the upper slab and the CIP, and can also reduce the corner angle of the right corner. .

In addition, when assembling the reinforcing wire mesh, the vertical H-shaped steel 822 is purchased at the top of the reinforcing steel mesh to be assembled, and the vertical H-shaped steel 822 of a certain length is installed only at both side CIP bulbs 800, and one side and the other upper portion are installed. It protrudes to a position where it is connected with the slabs 840 and 840 '. Since there is no lower slab, the member force is largely generated in the upper slab right corner portion, and thus will be used as a means for controlling the slab.

However, these CIP bulbs 800 are subject to constraints that are only possible in soil layers and impossible in rock sections. This is because the auger's equipment that excavates the ground cannot penetrate the rock. In this case, by using T4 equipment that can drill to the rock side every 2.0m, the bulb 800 is formed together with the internal excavation. After forming the bulb 800, construct the upper slab (840.850) and excavate to the rock section to install the CIP support anchor 807 and continue the internal excavation, but only to the soil layer, from the bottom of the lower slab cast concrete When cutting the rock (A) to continue the CIP reinforcement and poured concrete mixed with a powder waterproofing agent, a solid inner wall (880,880 ') is formed.

One side  Upper Slab Construction Process- S20

When the installation of the CIP bulb 800 is completed through the above-described process (S10), the section of the road section as shown in FIG. 120 is separated, and in this state, the entire compartment partitioned by the CIP bulb 800 in this state. It will be understood that either side of the third divided by the width source as a process for forming the upper slab first.

To this end, as shown in FIG. 121, the central portion of the upper portion of the upper slab width source 1/3 (as described above, the entire portion dividing the center of the wall made of CIP bulbs is named as the central portion, and this is denoted as 830 in the drawing). It also includes a column type formed by the bulb) (830) to the excavated H-peg to one side of the road portion near to excavate the asphalt layer and soil.

At this time, it was supposed to manufacture and install the concrete PC1 earth plate 804 that is applied in the fourth embodiment as an H-pile soiling facility.

In this way, after the trench work is carried out to a certain depth, the floor slab is equipped with concrete and formwork, and then the upper slab is installed.

At this time, the anchor bolt for connecting the corner reinforcement 860 may be configured in advance. This is to facilitate the installation immediately when installing the corner reinforcement 860.

In addition, it is possible to control the member force of the right angle part by installing a horizontal H-shaped steel 822 of a predetermined length connected to the vertical H-shaped steel 822 of a predetermined length protruding from the CIP bulb 800 of the side wall. It is a good idea to play a role.

In addition, since the PC strand 821 is placed in a position where the horizontal vertical H-shaped steel 822 is not disposed, tension fixation may reduce the member force value.

In the present invention, the upper slab is divided into three parts each of the total width source as shown in Figures 121 to 123, and undergoes a sequential pouring process, the upper part of the right side when viewed in the drawings (Fig. 121) for the understanding of the present invention. Named slab on one side of upper slab and denoted by reference numeral 840. Named slab on the opposite side as other upper slab, denoted by reference numeral 840 'and named center slab as center-side upper slab. Notation was divided into.

At this time, the reinforcing bar of one side upper slab 840 is arranged in a zigzag so as not to be connected at one place for connecting the reinforcement with the center side upper slab 850 in contact with the neighbor and after construction of the one side upper slab 840 Install a protective mortar.

In this way, after placing the one side upper slab 840, a trench construction (S30) for placing the other side upper slab 840 ', which will be described later, is performed, but one side upper slab does not interfere with the flow of traffic before. Cover the surface of the (840) must go through the cover process.

On the other hand, in the case of covering the soil to cover the zigzag reinforcement of the one side upper slab 840 and the center side of the upper slab 850 while covering the soil as a separate mud facility H pile (90) of Figure 138 ) A plurality of drilling holes 92 are provided in one flange, and the facility is installed by retreating a certain distance backward from the joint portion, but the anchor body 91 connected to the reinforcing bar is coupled to the bolt 93 at the drilling hole 92 position. Dogs are placed laterally, stacked and laid down to the ground in the same way.

When the facility is installed in such a way, when the upper slab 850 is destroyed in the middle side, a separate retaining facility installed at the construction of the upper upper slab 840 serves as the earth wall, so that the trench of the middle upper slab 850 is removed. It becomes easy.

On the other hand, in the construction of one side upper slab 840, unlike the above, it is possible to construct the trench construction method on both sides of one side and the other side with respect to the center as shown in Figures 124 and 125, depending on the road conditions.

The other side  Upper Slab Construction Process- S30

This process is after placing the one side upper slab 840 by the one side upper slab construction process (S20), and then cover the upper surface of one side upper slab 840 so that the flow of traffic is not disturbed, then the other side, one side As seen from the side (FIG. 122) facing the upper slab 840, it refers to a process of carrying out the trench to pour the upper slab (the other upper slab-840 ') on the left side.

In this manner, the periphery of the upper slab for pouring the other upper slab 840 'and then curing the other upper slab 840' by placing the upper slab to the upper side to construct the underground driveway as shown in FIG. 840,840 ') can be completed, and the process of installing the anchor bolt for connecting the corner reinforcement 860, the process of installing the horizontal angle control member H-beam (822) and PC strand (821) For example, the process of covering the soil, or the installation method of the H-piling and the trench and the earth plate is the same as the method of the upper slab 840.

On the other hand, the reinforcing bar of the other upper slab 840 'is to be connected in a zigzag arrangement so as not to be jointed at one place for connecting the reinforcement with the center upper slab 850 in contact with the neighbor and the construction of the other upper slab 840' Afterwards waterproofing material and protective mortar should be installed.

Center  Upper slab construction process S40

When the installation of the one side and the other upper slab construction process (S20, S30) is completed, as shown in Figure 123 to excavate the central side of the upper road portion to remove the ascon layer and soil.

As such, when digging the center side, there is a seismic facility that is connected to the H pile 90 and the anchor body 91 of FIG. 138 which is already installed during one side and the other upper slab construction process (S20, S30). Destruction is possible without this.

In this way, after proceeding to dig a certain depth, and then install the floor-level concrete and formwork to the dig surface, the upper side slab (850) is installed. At this time, the reinforcing bar of the upper slab is already connected in a zigzag state on one side and the other side, and the concrete is poured. After pouring, the waterproofing material and the protective mortar are constructed.

After the central upper slab 850 is installed, the H-pile is pulled out while backfilling with the process of releasing the bolts for pulling the H-peg installed in one and the other upper slab 840,840 '. Done.

In this way, the total width of the upper slab is divided into three parts in order not to place the reinforcing bar at the maximum position of the parent moment generated at the right angle part and the center part.

On the other hand, in the case of 1/2 construction, the reinforcing bar should be made in the center part, so it may be a burden due to the parent's cement. This is to reduce the size of the parent.

Corner portion  Reinforcement and Earthanka  Construction Process- S50

This process is the upper slab (840,840 ') or the inner wall (880,880) as a method for reducing the parent slag acting largely because the upper slab and the CIP is combined after completing the above-mentioned casting of the upper slab (840,840') To shorten the time between ').

To this end, only part of the corner is excavated to install the stiffeners 860 at regular intervals.

At this time, during the construction process (S10) and the upper slab construction process (S20, S30) for the formation of the CIP bulb 800 is to simply assembling and fastening the yarn-reinforced material 860 to the anchor bolts already embedded.

Since the space between the upper slab and the CIP bulb 800 is shortened due to the installed sabotage steel 860, the member force decreases, and thus the safety is further maintained, and the end surface and the final drilling surface of the sabotage steel 860 in the inner wall 880,880 '. Earth anchors are used to reduce the length of the bridge. The facility of Earth Anca is advantageous in terms of economical ability to reduce the absent force of the inner wall (880,880 ′) and to reduce the length of the entry.

On the other hand, if you use the PC strand (823) to buy a strain on the CIP bulb 800, the same effect can be obtained even without the earth anchor, it will be natural that those who use the present invention can be selectively applied. .

Both sides Inner wall  Foundation and central wall or column reinforcement construction process- S60 -2

This step is a step for forming the underground roadway by constructing the inner wall foundations (870,870 ') and the central portion (830) after the above-described corner portion reinforcement and earth anchor construction process (S50) is completed.

After the discarded concrete is formed in the excavated spaces at both sides, the inner wall foundations 870 and 870 'are poured into the lower end of the side wall 831 of the excavated portion.

Here, the inner wall foundations 870 and 870 'refer to a pour body that is placed on the bottom surface of the underground driveway, as shown in the drawing, and pours up to the haunting portion that is in contact with the inner side of the side wall 831.

After excavation and construction of the space on both sides as described above, when the casting process of the inner wall foundations (870,870 ') is completed, placing the reinforcement bars on the left and right sides of the central portion 830, the CIP bulbs 800, which are constructed by places, By placing the reinforcing wall 890 to be bundled together to form a central portion 830 of the completed form.

Both sides Inner wall  Construction Process- S70

Some of the inner walls 880 and 880 'connected to both sides and poured into the inner side of the side wall 831 are constructed after dismantling the earth anchors connected to the inner wall foundations 870 and 870', and the remaining inner walls 880 " Some inner walls 880 and 880 ′ are cured and then constructed while removing the corner reinforcement 860. However, when the remaining inner wall (880 ") is cured, it may be settled by the contraction of the concrete, and a fine gap may be generated with the upper slab (840, 850, 840 '), which is completed by filling the non-shrink mortar (883).

Finishing Construction Process- S80

When the above process is completed, the process of the underground driveway is completed by installing sidewalks and electric facilities, tiles and ascons inside the underground driveway.

In the construction of the underground roadway using the CIP bulb 800 through a series of steps as described above, FIG. 130 shows the reinforcement 881 and the reinforcement 871 and 872 of the side wall 831 and the inner wall foundation 870. The connection is fixed.

Among the reinforcing bars 810 and 811, the reinforcing bars 811 adjacent to the inner wall 880 and the reinforcing bars 881 of the inner wall body 880 integrally placed on the side surfaces of the lower slab 870 were respectively connected and fixed. Another reinforcing bars (844, 844 ') is connected to the reinforcing bars (810) of the reinforcing bars (810,811) embedded in the CIP bulb 800 forming the side wall (831).

In addition, the reinforcing bars close to the inner wall (880) of the reinforcing bars (810,811) embedded in the reinforcement reinforcement and the side wall 831 forming the reinforced reinforcement (881) of the inner wall (880) of the inner wall 880 ( Connection bars 882 for connecting the reinforcing bars arranged in contact with the strip reinforcing bar 820 in the horizontal direction 811 to be spaced apart from each other at equal intervals. This connection structure will be equally applied to the upper left and right sides of the underground road.

Further, when reinforcing the upper slab 840,840 ', the reinforcing bars 843, 843' are embedded in the ground while being covered with a covering, and then the reinforcing bars 843, 843 'that were embedded during the remaining inner wall 880' 'facility process. And the reinforcement 881 embedded in the inner wall 880 are interconnected in a state in which the covering is removed.

133 is shown in the 1/3 construction sequence as shown in the drawing, each of the upper slab (842,842 ', 841,841' / 852,851) reinforcing bar should be connected in a zigzag connection without connecting in one place.

That is, each of the reinforcing bars (841,842 / 851,852) to be embedded in one side and the middle side upper slab (840,850) should be connected, and each of the reinforcing bars (841 ', embedded in the other side and the center upper slab 840', 850), 842 '/ 851,852) should be connected. At this time, as described above, it is important that each reinforcing bar is connected to each other and then placed in place.

Figure 134 shows the details shown in the 1/2 construction sequence, each of the upper slab (840, 840 ') reinforcement and the reinforcing bar in the CIP bulb 800 will be a structural disadvantage due to the buoy as a connection in a certain tension Therefore, it is important to increase the cross-sectional thickness of the central upper slab to the outside to reduce the parenting.

To this end, each of the reinforcing bars (841,841 '/ 842,842') embedded in each upper slab (840,840 ') must be fixedly connected to the central reinforcing bar 832 of the CIP bulb 800, as shown in the center portion 830 Binding and fixing the position which is in contact with each upper slab 840,840 'which is the upper side of the CIP bulb 800 forming a) and pours the upper slab 840 on one side. At this time, the reinforcing bars (841, 842) of a certain length in order to connect with the reinforcing bars of the other upper slab is arranged in a zigzag before placing so that the other bars (841 ', 842') of the other upper slab (840 ') is not connected. Fix the end of ') with a coupler or gas pressure welding method. In this way, the upper slabs 840 and 840 'and the center portion 830 are firmly connected.

FIG. 135 is a view illustrating a portion “E” in FIG. 127. In an enlarged view, an example for fixing the corner reinforcement 860 to one side of the CIP bulb 800 is illustrated. In connection with the anchor bolt pre-embedded in 800, the corner reinforcement 860 is configured to have a sufficient supporting force. This connection also applies to the upper slab 840,840 '.

 FIG. 136 shows one side of the CIP bulb 800 constituting the side wall 831 to be connected to the outside of the inner wall 180 while being connected by the connecting reinforcing bars 882 as shown in the drawing. The band reinforcing bars 820 surrounding the reinforcing bars 810 and 811 to be buried in the bulbs 800 should be finished by the panel 802 such as plywood so as to be exposed to the outside by the pre-installed band 803.

In order to be constructed as described above, it is preferable that the panel 802 is formed to be poured to cut one side when forming the CIP bulb 800 for forming the sidewall 831 in both sidewall CIP bulb construction process (S10).

As described above, the side wall 831 obtained by the panel 802 is provided with a band reinforcing bar 820 covering the reinforcing bars 810 and 811 embedded in the CIP bulb 800 constituting the side wall 831.
