The temporary earth retaining facility construction method according to an embodiment of the present invention is for installing a temporary earth retaining facility to prevent the soil from collapsing in the process of excavating the floor, hereinafter referred to as 'this method' for convenience of explanation.

1 and 2, the present method (method for constructing temporary retaining facilities according to an embodiment of the present invention) includes a first retaining construction step (S1), an excavation step (S2), a second retaining retaining construction step (S3), And a support construction step (S4).

1 to 3, the first earth retaining construction step (S1) includes a step (S11) of driving the post 11 of the wooden wall 1 to the floor of the construction site (see [A] in FIG. 2). do.

Referring to FIG. 3, the support 11 may be an H-beam, and the wooden wall 1 (H-PILE + retaining board) may include an earth plate 12 installed on the H-beam.

Illustratively, step (S11) may include a process of drilling the floor of the construction site through a drilling device such as an auger and inserting H-beams.

1, 2, and 4, in the first earth retaining construction step (S1), the CIP wall 2 including a plurality of concrete piles 21 is constructed by drilling the floor of the construction site and pouring concrete. (S12) (see [A] in FIG. 2).

In the step (S12), the drilling of the floor of the construction site may be performed by drilling equipment such as an auger as described above, and H-beams are inserted into some of the plurality of grooves formed by drilling the floor, or the rest except for some A plurality of concrete piles 21 may be manufactured by inserting a reinforcing bar member including a main reinforcing bar 211 having a length in the vertical direction and a strip reinforcing bar 212 surrounding the main reinforcing bar 211 and then pouring concrete.

The CIP wall 2 described above includes a plurality of concrete piles 21 arranged in a horizontal direction.

Here, the above-described vertical direction refers to a plane-bottom direction with reference to FIG. 4, and the horizontal direction refers to a left-right direction with reference to FIG. 4, and the same will be applied in the following description.

1, 2, and 4, the first earth retaining construction step (S1) includes a step (S13) of injecting a chemical solution containing cement into the rear (outside) of the CIP wall 2.

Front (inside), which will be described later, is when the construction site is viewed on a flat surface. It refers to the excavation surface (excavation site) direction (direction side) based on the retaining wall to be described later including the CIP wall (2), and the rear (outside) refers to the retaining wall described later when the construction site is viewed on a plane. As a reference, it means the opposite direction (direction side) to the front (inside). The same applies below.

The chemical solution may be a mixture including the above-described cement, water, and an accelerator (eg, including calcium aluminate).

Illustratively, in the step (S13), the start water is sent to the inner pipe of the double pipe to pierce the rear between the neighboring concrete piles 21, and the rod is moved upward while sending the pressure water to the exterior of the double pipe. The tip device protrudes to form a cylinder-shaped induction space, and the chemical solution can be injected through the inner tube and the outer tube.

That is, the rear of the retaining wall is pierced with a steel pipe, the steel pipe is lifted upward, and the chemical solution is injected into the hollow inside the steel pipe, whereby cement, sand and water at the rear of the retaining wall are mixed and cured.

Through this, as the cement and sand of the chemical react and cure, the space between the neighboring concrete piles 21 is blocked at the rear of the CIP wall 2, and the sand and water move into the space between the neighboring concrete piles 21. can be effectively suppressed.

1 and 2, in the excavation step (S2), the pillar 11 (the connection line of the neighboring pillar 11, the connection line between the pillar 11 and the CIP wall 2) and the CIP wall 2 It is a step of excavating the inside of the construction site (see [B] in FIG. 2) based on (based on the retaining wall described later).

The excavation step (S2) may be performed by equipment such as a poclaine, and the inner floor of the construction site may be excavated to form an excavation surface.

Illustratively, in the excavation step (S2), when the inside of the construction site is wide, an open cut method may be used to perform the excavation process while creating a slope. This has the advantage of suppressing soil collapse.

1 to 3, the second earth retaining construction step (S3) is a step of manufacturing a wooden wall (1) by installing an earth plate (12) on a support (11).

Illustratively, the earth plate 12 may be inserted into a groove formed by a web and a flange of an H-beam to connect neighboring H-beams and be installed on the H-beam. The soil plate 12 may be mutually coupled with the holding column 11 by a known conventional method (eg, bolting coupling, etc.).

In this way, the method can construct a retaining wall including a wooden wall 1 and a CIP wall 2, including the first retaining construction step (S1) and the second retaining construction step (S3).

The wooden wall (1) is easy to construct and reuse of materials, so that the amount of the wooden wall (1) can be greater than the amount of the CIP wall (2) as needed. On the contrary, depending on the characteristics of the construction site, in places where the soil is likely to collapse, more CIP walls (2) with excellent rigidity may be constructed than wooden walls (1).

1, 2, 4, and 6, the support construction step (S4) is a step (S41) of connecting one side and another side of the retaining wall with a support 3 (strut) , Step (S42) of supporting the inside (inner surface) of the retaining wall at an angle using a raker 4 installed on the excavated surface formed in step (S2) (S42), and an anchor 5 connected to the retaining wall ) (earth anchor, EARTH ANCHOR) may include one or more of the steps (S43) of driving the outside of the construction site (see [B] and [C] in FIG. 2).

The (S41) step is a step of connecting a horizontal plate 81 and a bracket 8 including an inclined beam 82 provided at the lower front of the horizontal plate 81 and inclined downward to the rear to the inside of the retaining wall. (S411) may be included.

In addition, step (S41) may include a step (S412) of installing a wale 6 (exemplarily formed as a frame) on the horizontal plate 81 so as to be disposed along the circumference of the retaining wall when viewed from a plan view. there is.

The above retaining wall has a height (length) in the plane-bottom direction based on FIG. 4, and a width in the left and right direction based on FIG. 4. It may have a thickness in the vertical direction based on Figure 4, the circumference of the retaining wall means the width direction of the retaining wall.

Therefore, the wale 6 is arranged along the circumference of the retaining wall when viewed in plan and connected to the inside of the retaining wall, so that the earth pressure acting on the retaining wall is evenly distributed to the retaining wall.

On the other hand, referring to FIG. 5, step (S41) is performed after step (S412) described above, and step (S413) of installing a filling material 7 (filler) between the retaining wall and the wale 6 can include

Illustratively, the filling material 7 may be installed on the top plate 81 and disposed between the wale 6 and the retaining wall.

Among the above-mentioned retaining walls, the wooden wall (1) is installed by inserting the earth plate (12) into the groove of the H-beam, so that the earth plate (12) and the wale (6) may have a space apart along the horizontal direction, and the CIP wall (2 Each of the plurality of concrete piles 21 forming the ) has a curved front surface when viewed on a plane, so that a separation space is generated between the grooves and wales 6 between neighboring concrete piles 21.

The above filling material 7 fills the space between the retaining wall and the wale 6 and may be exemplarily cement, mortar, or the like.

As such, the present method includes a step (S413) of installing a filling material 7 (filler) between the retaining wall and the wale 6, thereby filling the gap between the retaining wall and the wale 6 having various shapes ( 7) has the advantage of uniformly distributing the earth pressure acting on the retaining wall.

3 and 4, step (S41) is a step of connecting the length adjusting means 9 to the front of the wale 6 and connecting the brace 3 to the front of the length adjusting means 9. (S414) may be included.

The length adjusting means 9 is illustratively connected to the connecting plate 91 connected to the front of the wale 6, the nut member 92 provided in front of the connecting plate 91, and the front of the brace 3 It may include a bolt member 93 that is connected to and is moved in the horizontal direction by being fastened (screwed fastening) with the nut member 92 at the rear.

In addition, the length adjustment means 9 may include a handle provided on the outer surface of the bolt member 93, and the entire length of the length adjustment means 9 may be adjusted by rotating the bolt member 93 by rotating the handle.

Therefore, by adjusting the distance between the wale 6 and the brace 3, there is an advantage in that it is possible to effectively suppress the forward inclination of the retaining wall due to earth pressure.

A nut is fastened to the front of the bolt member 93, and a plate connected to the brace 3 may be connected to the front of the nut.

In the step (S43) of driving the anchor 5 (EARTH ANCHOR) connected to the retaining wall to the outside of the construction site, the anchor 5 has its upper end connected to the wale 6, and the lower end of the retaining wall It can penetrate the wall and be buried in soil or rocks outside the construction site.

As such, when the method includes a step (S41) of connecting one side and the other side of the retaining wall with the brace 3, repair and reinforcement are easy as the excavation progresses, and materials can be reused. There is an advantage to being

In addition, it is possible to check the stress state of the brace (3), and it is possible to visually observe the displacement over the entire section, so there is an advantage that management is easy.

In addition, when the present method includes the step (S42) of supporting the inside of the retaining wall using a raker installed on the excavated surface, the excavation width is not limited and the excavation width is large, which is disadvantageous to cost and stability. It has the advantage of being able to support it effectively.

In addition, when the method includes the step (S43) of driving an anchor connected to the retaining wall to the outside of the construction site based on the support and the CIP wall, the construction cost is low and there are no obstacles inside the construction site, so that work or underground structures It has the advantage of improving work efficiency such as construction.

That is, this method has the advantage of being able to construct a more structurally stable retaining wall including the support construction step (S4).

Referring to [D] of FIG. 2, as concrete is poured on the excavation surface, the support member (one or more of the support member 3, the anchor 5, and the raker 4) may be sequentially removed. Since the brace 3 is bolted to the wale 6, it is removed by releasing the bolting, and the same is true of the raker 4. The steel wire of the anchor 5 described above can be pulled inward and removed.

6 and 7, step (S41) may include a step (S451) of applying a mixture of a waterproofing material (GS) and a functional additive (G) to the outer surface of the brace (3).

The waterproof material GS is applied to the outer surface of the brace 3 and may include 5 parts by weight of urethane (compared to 0.2 parts by weight of latex described later). The waterproofing material GS adds waterproofness to the brace 3 by including urethane.

The functional additive (G) includes 0.2 parts by weight of latex, a stretchable outer shell material (G1) in the form of a fiber and dispersed in the waterproofing material (GS), and 0.4 parts by weight of bismuth nickel iron oxide, and is in the form of particles, but the stretchable outer shell material (G1) contains 0.2 parts by weight of a mixture of variable material (G2), magnetite, polyacrylic acid, and polyoxyethylene accommodated inside, and It includes a cationic material (G3) provided at either end of both ends and 0.2 parts by weight of p-styrenesulfonic acid (SSNa), and the other end of the stretchable envelope (G1) on both sides is included. It includes an anionic polymer material (G4) provided at one end (the ratio of each component of the functional additive (G) is based on 0.2 parts by weight of latex).

Referring to FIG. 7 , the functional additive (G) will be described in more detail. The elastic outer cover material (G1) includes latex capable of elastic deformation in order to respond to the volume change of the deformable material (G2) to be described later.

If the amount of latex in the elastic outer cover material (G1) is less than 0.2 parts by weight, the variable material (G2), which will be described later, cannot be sufficiently wrapped in a sufficient thickness, and the variable material (G2) may be lost. If the amount of latex exceeds 0.2 parts by weight, the functionality There is a problem in that dispersibility is reduced because the weight of the additive (G) is excessively increased and the functional additive (G) moves to the lower side of the waterproof material (GS) in a mixed state with the waterproof material (GS).

Common materials such as waterproofing materials (GS) generally increase in volume as the temperature increases. However, bismuth nickel iron oxide (BiNi1-xFexO3) included in the variable member G2 and used as an oxide ceramic material decreases in volume as the temperature increases. Bismuth nickel iron oxide was used because it has a 'negative thermal expansion' effect that is more than twice that of conventional materials (eg zirconium vanadate, etc.) at room temperature.

[A] of FIG. 7 is a view for explaining the functional additive (G) at a first temperature (eg, 10° C.) of room temperature. [B] of FIG. 7 is a view for explaining the functional additive (G) at a second temperature (eg, 20° C.) higher than the first temperature of room temperature.

In FIG. 7 , when the waterproof material GS increases from the first temperature to the second temperature, the volume increases. In this case, there is a problem in that the waterproof material GS is bent and wrinkled. There is a problem in that the waterproofing material GS applied through this is separated from the brace 3 and peeling may occur.

The above functional additive (G) is for suppressing the volume increase (or horizontal direction (left and right direction with reference to FIG. 7) of the waterproofing material (GS) increased) due to the temperature rise, and the variable material (G2) is the above-mentioned As the temperature increases, the volume actually decreases.

The elastic outer cover material G1 is said to be a material that is elastically deformed. As the volume of the deformable material G2 is reduced, as shown in [B] of FIG. In this way, by including the variable material (G2) in the functional additive (G), the waterproofing material (GS) suppresses the change in volume according to the temperature change, thereby suppressing the wrinkling, and thus effectively suppressing the occurrence of exfoliation or the like. There are advantages to being able to do it.

It is preferable that 0.4 parts by weight of the bismuth nickel iron oxide of the variable member G2 is used. However, when less than 0.4 parts by weight of the bismuth nickel iron oxide is used, there is a problem in that the volume change of the waterproofing material GS cannot be effectively suppressed. When the nickel iron oxide exceeds 0.4 parts by weight, there is a problem in that the dispersibility of the functional additive (G) is lowered by excessively increasing the weight of the functional additive (G).

The deformable material G2 (bismuth nickel iron oxide) is preferably in a particle shape, and a plurality of deformable materials G2 in a particle shape can be accommodated in the fibrous stretchable cover material G1. As described above, since the bismuth nickel iron oxide of the deformable material G2 has a plurality of particle shapes, it is possible to change the shape of the flexible outer cover material G1, which is fibrous and elastically deformable because it is free to move, and the present composition (the waterproofing material ( The shape of the functional additive (G) may also be variously changed in response to the shape of the support (3) to which the mixture of GS) and functional additive (G) is applied. For example, in FIG. 7, the functional additive (G) has a '-' shape, but can be bent and changed into various shapes such as 'ㄱ' shape, 'ㄴ' shape, and 'S' shape. That is, it is possible to improve the adhesion between the waterproofing material (GS) and the functional additive (G).

In addition, the skin material (G1) of the functional additive (G) is an elastic material, and as described above, it can add toughness to the waterproof material (GS) by including fibrous latex, so that the waterproof material (GS) is not torn or damaged. It has the advantage of being able to suppress things effectively.

As described above, the cationic material G3 is provided at either end (right end in FIG. x) of both ends of the stretchable outer cover material G1, and is made of magnetite or polymethacrylic acid. And it was used to add a positive polarity to either side of the functional additive (G) including polyoxyethylene.

Magnetite became magnetized when it received an external magnetic field, and when the external magnetic field was removed, the residual magnetism disappeared, so it was used because there were no side effects caused by residual magnetism. Magnetite may be provided on either end side of the stretchable outer covering material G1.

Polymethacrylic acid is coated on the surface of the magnetite, and contains a plurality of carboxyl groups to form coordinate bonds with magnetite at multiple bonding points, thereby increasing coating stability.

Polyoxyethylene reacts with a carboxyl group that does not form a coordination bond with magnetite on the surface of polymethacrylic acid to form a stable bond through an amide bond to impart positive charge characteristics to the magnetite. The surface positive charge of the above cationic material (G3) may have a surface zeta potential of +30 mV or more.

The cationic material (G3) is preferably used in an amount of 0.2 parts by weight. When less than 0.2 parts by weight of the cationic material (G3) is used, the positive charge of the functional additive (G) is not sufficient, and the cationic material (G3) exceeds 0.2 parts by weight. When used, there is a problem in that the weight of the functional additive (G) is excessively increased.

The anionic polymer material G4 is provided on the other side of both ends of the stretchable outer cover material G1, and as described above, may include p-styrenesulfonic acid, in addition, the hydrogel pre-polymer can include

The anionic polymer material (G4) may be a mixture of p-styrenesulfonic acid and a hydrogel pre-polymer (1:19 ratio) and UV curing.

It is preferable that the anionic polymer material (G4) contains 0.2 parts by weight of p-styrenesulfonic acid. If less than 0.2 parts by weight of p-styrenesulfonic acid is used, the negative charge of the functional additive (G) is not sufficient, and the p-styrenesulfonic acid is not sufficient. When the amount of styrenesulfonic acid exceeds 0.2 parts by weight, there is a problem in that the weight of the functional additive (G) is excessively increased to reduce dispersibility.

When the waterproofing material (GS) includes a large number of units (GU) of the functional additive (G), the neighboring units (GU) are separated by shear force in a stirring (mixing) situation to improve the dispersibility of each component in the present composition. can

As described above, the functional additive (G) is said to include the anionic polymer material (G4) of the cationic material (G3) at both ends of the stretchable envelope (G1), respectively. After mixing, the waterproof material (GS) is a support ( 3), adjacent units (GU) can be attached by electrostatic attraction. Toughness may be imparted by electrostatic attraction between materials G4.

At this time, the magnetite of the cationic material (G3) is a mineral that may be damaged by impact, but the anionic polymer material (G4) is a polymer material that is basically more easily deformable than a mineral. Therefore, when neighboring units (GU) are attached to each other by electrostatic attraction, the shape of the anionic polymer material (G4) is changed by the cationic material (G3), thus reducing the impact applied to the cationic material (G3) Therefore, it is possible to effectively suppress the damage of the functional additive (G).

The present invention described above with reference to the accompanying drawings can be variously modified and changed by those skilled in the art, and these modifications and changes should be construed as being included in the scope of the present invention.
