Abstract

The present invention relates to a construction method for a self-standing retaining wall using a construction method of a soil retaining plate and a reinforcing member, capable of performing deep excavation even if an embedded length is short in a section with a narrow property line in a downtown area. The construction method for a self-standing retaining wall comprises: a double I-beam embedding step of embedding a double I-beam after the ground is bored; a partial excavation step of excavating only a position in which the double I-beam is formed; a step of manufacturing a double I-beam type pile by connecting a horizontal reinforcing member to the double I-beam; and a step of installing a soil retaining plate. The construction method for a self-standing retaining wall can perform the deep excavation even when there is a lack of the property line. The horizontal reinforcing member capable of forming resistance by active earth pressure is connected to an in-site concrete pile. So, even if the embedded length of the in-site concrete pile is short and the in-site concrete pile is not deeply embedded, the construction method for a self-standing retaining wall can improve performance of the deep excavation and constructability. Also, a small inclination reinforcing member and a vertical resistance reinforcing pile connecting the horizontal reinforcing member combined with the in-site concrete are formed. So, an additional bearing force corresponding to the active earth pressure is formed. Therefore, even if the embedded length for forming passive earth pressure is short, the construction method for a self-standing retaining wall using the construction method of the soil retaining plate and the reinforcing member can perform the construction of a retaining wall. Moreover, the construction method for a self-standing retaining wall using the construction method of the soil retaining plate and the reinforcing member can perform deep excavation even when the ground is soft.

Description

Construction method for earth self-retaining wall using reinforcing member and Soil retaining plate construction method}

The present invention relates to a self-supporting earth retaining method using a reinforcing member and a earth plate method that can dig into a deep depth even when the root boundary is short in a narrow section of the downtown boundary of the downtown area.

The mud construction method is a temporary structure that prevents surrounding soil or groundwater from entering the excavation ground when installing a direct foundation, pile foundation, or underground structure.

Temporary facilities are used during construction and are demolished after completion of construction. Temporarily neglected, which is temporarily used to construct the main body structure. Recently, the construction has become large and complicated, and the cost, construction volume, and the proportion of air occupied by the entire construction. It has become very important because it has grown.

The mud construction method consists of a mud wall supporting the surrounding soil and a support material supporting the mud wall, and can be classified into various types according to the type of the mud wall and the support material.

Typical construction methods for mudguards include the H beam and earth plate construction methods, sheet pile construction methods, main-type mud construction methods, and slurry wall construction methods.

The H-beam and earth plate construction method is a method in which the H-beam and the earth plate are installed at regular intervals, and the earth plate is installed between the H-beams at the same time as excavation, and a mud wall is installed to support the mud wall by installing a strut brace or anchor. Although the air is short, there is a disadvantage in that it is necessary to reinforce grouting and take measures against the heaving phenomenon due to poor water resistance.

The sheet pile method is a method of continuously connecting steel piles to form a retaining wall, which is suitable for soft grounds due to its high degree of water repellency.

The main heating type is a method of forming concrete retaining walls by successively placing concrete piles on-site. It is a low-noise method that reinforces the retaining walls by placing reinforcing bars and H beams inside the piles, providing excellent water resistance and high wall rigidity. Although there are few surrounding settlements, there are disadvantages that the air is relatively long and the construction cost is increased.

On the other hand, in the main heating method, the CIP method of filling the pre-assembled reinforcing bars and coarse aggregates in the excavated ground and injecting mortar, constructs piles in the field, mix the soil in the excavation hole with cement pool, and press H beam or rebar There is a soil cement method.

The slurry wall method is a method of excavating while preventing the collapse of the ground using a stabilizer when excavating the ground, inserting a rebar net therein and pouring concrete to continuously install the concrete retaining wall. This method is suitable for downtown construction considering the safety of construction, pollution problems, and the influence of adjacent buildings.

On the other hand, the above-mentioned mud construction method is forced to apply a limited construction method due to the adjacent structures (roads, buildings, etc.) when excavating downtown, and the typical urban excavation method uses H beam as the main material and types it in the planned location. A method of excavating and descending is generally used.

At this time, as a method of forming a wall between the H beams, as described above, a wooden board (H beam and earth plate construction method) or a field pile pile, that is, a soil cement and a concrete pile construction method, is used as a temporary wall.

In the case of using cast-in-place piles, concrete is poured on top of it to fix the top by integrating the H-beam and the top of the cast-in-place pile, which is called a cap beam.

In the case of the related art, the cap beam was used only to reduce the horizontal line of the H beam and the upper displacement of the cast-in-place concrete pile.

That is, it was not used as a role as a belt supporting the wall during excavation.

Therefore, in order to excavate, it is necessary to separately install a first-stage girdle close to the lower portion, which leads to an uneconomical construction.

In particular, all of the above-described construction methods have a problem in that they cannot be actually constructed by earth pressure in a narrow section of the downtown boundary.

Moreover, in order to cope with the dynamic earth pressure generated in the pile, the ground near the ground must be about 1.5 to 2.5 times more than the exposed pile. In the case of a situation to do, the work was very difficult in a small space.

In order to solve the above problems, various types of mudguard methods have been proposed in the past.

As an example, there is a two-row self-supporting earth retaining method such as Korean Patent Registration No. 10-1692541 (hereinafter referred to as 'patent document 1').

The two-row self-supporting retaining method as in Patent Document 1 can increase the bearing capacity of the pile by connecting the front and rear row piles and then connecting them.

In addition, there is a construction method of installing a raker in a two-row self-supporting pile construction method, such as Korean Patent Registration No. 10-0964995 (hereinafter referred to as 'patent document 2').

The construction method as in Patent Document 2 is made to increase the bearing capacity of the retaining wall by placing the raker in an inclined space during the construction method of Patent Document 1 described above.

(Patent Document 1) KR10-1692541 B1 Two-row self-supporting mud construction heat transfer, post heat pile connection structure

(Patent Document 2) KR10-0964995 Two-row thumb pile earthing method using B1 raker

However, the two-row self-supporting earth retaining method as in Patent Document 1 can be very useful in a narrow section of the land boundary line by connecting the front and back piles after connecting the front and back piles, but the construction efficiency is reduced by double-inserting the pile There was a problem.

In addition, the above-mentioned Patent Document 2 was able to increase the bearing capacity of the retaining wall by additionally installing a raker in the configuration of Patent Document 1, but the above-described raker must be configured to a size sufficient to form a sufficient supporting force, so the worker A. There was a problem in that the work space was very narrow and the workability was deteriorated during the construction of a building wall or foundation.

The self-supporting earth retaining method using the reinforcing member and the earth plate method according to the present invention for solving the above problems is excellent in torsional strength and buckling strength due to a higher cross-section coefficient than the existing H beam, even when the earth boundary line is insufficient, so deformation due to earth pressure An object of the present invention is to provide a self-supporting earth retaining method using a reinforcing member capable of digging to a deep depth and a earth plate method by using a double eye beam type self-supporting earth retaining file that does not occur.

Another object of the present invention is a non-exposed section for forming a manual earth pressure corresponding to the main earth pressure by a double eye beam type pile produced by combining a horizontal reinforcement member extending in a horizontal direction in which a trench space is formed in a double eye beam. Even if the length of the near-entrance is short, sufficient support capacity to cope with the main earth pressure is formed, so that even when the double eye beam is not deeply inserted, deep-diving can be performed. The purpose of this is to improve the supportability of the double eye beam even more when the horizontal reinforcement member is coupled to the eye beam to improve the workability.

Another object of the present invention is a double exposed by a dug by combining a small size inclined reinforcement member connecting a double reinforced beam and a horizontal reinforcement member after combining a horizontal reinforcement member with a double eye beam in the step of manufacturing a self-supporting pile. The additional support force corresponding to the main earth pressure generated in the exposed section of the eye beam is formed, so that even if the length of the near entrance, which is the non-exposed section of the double eye beam for forming the passive earth pressure, is shortened, it is possible to sufficiently construct the earth, The purpose is to prevent structural deformation of the beam and to ensure a sufficient working space.

Another object of the present invention is to shorten the length of the near-entry section, which is a non-exposed section of a double eye beam for passive earth pressure by combining a vertical resistance reinforcement pile that is inserted into the ground of a trench to a horizontal reinforcement member during the self-supporting pile manufacturing step. Even if it is possible to sufficiently perform the construction of a mud, as well as in the case of soft ground, the purpose is to be able to dig deeply.

According to the present invention, even when the ground boundary line is insufficient, the torsional strength and buckling strength are higher due to the higher cross-section coefficient than the existing H-beam, so it is not deeply deformed by using the double eye beam type self-supporting pile which does not cause deformation due to earth pressure. Can be performed.

In addition, by using a double eye beam type file produced by combining a horizontal reinforcing member extending in a horizontal direction in which a trench space is formed, a length of the near-entry, which is a non-exposed section for forming a passive earth pressure corresponding to the main earth pressure, is produced by a double eye beam type pile. Even if it is shortly formed, sufficient support force to cope with the main earth pressure is formed, so that even if a double eye beam is not inserted at a deep depth, deep depth drilling can be performed. In particular, horizontal reinforcement of the double eye beam at a position in contact with the ground of the trench When the members are joined, the support force of the double eye beam can be further improved to improve the workability.

Then, in the step of manufacturing a file for self-supporting mudguard, after combining the horizontal reinforcement member with the double eye beam, combine the double eye beam and the small size inclined reinforcement member that connects the horizontal reinforcement member in the exposure section of the double eye beam exposed by digging. By forming an additional supporting force corresponding to the generated main earth pressure, even if the near-length length of the non-exposed section of the double eye beam for passive earth pressure is formed shortly, it is possible to sufficiently construct the soil, as well as prevent structural deformation of the double eye beam and You can secure enough work space.

In addition, even if the length of the near-entry, which is a non-exposed section of the double-eye beam for passive earth pressure, is shortened by combining the vertical resistance reinforcement pile that is inserted into the ground of the soil during the self-supporting pile construction step in the step of making the pile, it is sufficient to construct the soil. Of course, it is a useful invention that can be carried out at a deep depth even in the case of soft ground.

In addition, after the horizontal reinforcing member is combined in the step of manufacturing the self-supporting pile, the inclined reinforcing member may be further coupled between the double eye beam and the horizontal reinforcing member.

In addition, in the step of manufacturing the self-supporting pile, the horizontal reinforcing member may be combined with a vertical resistance reinforcement pile that is inserted into the ground.

In particular, the vertical resistance reinforcing pile in the step of manufacturing the self-supporting earthenware pile is inserted into the ground before breaking the horizontal reinforcing member to the double eye beam, and then the horizontal reinforcing member is coupled to the double eye beam and the vertical resistance reinforcing pile or Alternatively, after the horizontal reinforcing member is coupled to the double eye beam, the horizontal reinforcing member and the vertical resistance reinforcing pile may be combined after the vertical resistance reinforcing pile is inserted into the ground of a place where the end of the horizontal reinforcing member can be coupled.

It is a structure that is inserted into the ground (G1) when the mud is constructed.

The double eye beam 10 may be made of a high strength steel material.

Next, the horizontal reinforcing member 20 is coupled to the first plate 11 of the double eye beam 10, which is inserted under the ground G1 during the construction of the earthenware and is subjected to the main earth pressure, thereby supporting the double eye beam 10. It is a structure for forming.

Here, the horizontal reinforcing member 20 is horizontally extended in the digging space (O) direction, but the horizontal extension length is the depth of the digging depth and the near end of the double eye beam (10) inserted under the digging ground (G2). It depends on.

In particular, the material of the horizontal reinforcement member 20 is preferably made of a steel material.

Meanwhile, in the present invention, the inclined reinforcement member 30 may be further included.

The inclined reinforcing member 30 is configured to be inclined between the double eye beam 10 extending in the vertical direction and the horizontal reinforcing member 20 extending in the horizontal direction to connect them.

More specifically, among the double eye beams 10 extending in the vertical direction, the exposed section A1 exposed without being inserted into the trench ground G2 and the horizontal reinforcing member 20 extending in the horizontal direction are supported. It is a configuration to do.

Here, the inclination angle of the inclined reinforcing member 30 is varied depending on the depth of excavation and the depth of intrusion of the double eye beam 10 in the ground (2). .

In addition, in the present invention, the vertical resistance reinforcement pile 40 can be further combined.

The combination of the member 20, the inclined reinforcing member 30, and the vertical resistance reinforcement pile 40 may be combined using a fastening means such as welding or a bolt / nut.

2. Self-supporting earthing method

The self-supporting earthing method using the reinforcing member and the earthing plate method according to the present invention consists of a double eye beam incorporation step, a partial excavation step, a self-supporting earthing file manufacturing step, and a landing plate installation step, and the detailed process is as follows.

end. Double Eye Beam Entry Stage

This step is a step in which the double eye beam 10 constituting the double eye beam type file 100 is brought into the ground. As shown in FIG. 3, the ground G1 is drilled at regular intervals to drill the hole H. After forming, the double eye beam 10 may be introduced into the plurality of perforation holes H to complete this step.

Here, the formation of the perforation hole (H) can be carried out by using a conventional auger, it may or may not use a casing depending on the state of the ground.

In particular, the drilling hole (H) in this process should be performed in view of the depth for the trenching space (O) and the non-exposed section (A2), which is near the double eye beam (10).

I. Partial excavation stage

This step is a step of forming a partial excavation part E by excavating only the position at which the double eye beam 10 is inserted after the double eye beam insertion step as shown in FIG. 4.

This step is a previous step for producing the double eye beam type file 100 described above, and the double eye beam is partially excavated by only partially excavating the position at which the double eye beam 10 is inserted at an excavation depth equal to the depth of drilling planned by the first operator. This is a step to secure space for production of the type file 100 and prevent the collapse of the excavation space.

All. Self-supporting mudguard file production step

This step is a step of manufacturing the double eye beam type pile 100 by combining the horizontal reinforcing member 20 with the double eye beam 10 through the partial excavation part E formed in the previously performed partial excavation step.

Here, the horizontal reinforcement member 20 in the present invention is coupled to the double eye beam 10 at a position in contact with the trench ground G2 as shown in FIG. 5 by means of fastening (not shown in the drawing) or welding. do.

Particularly, in this step, as shown in FIG. 6, the double eye beam type pile 100 may be manufactured by further combining the inclined reinforcing member 30 that is inclinedly coupled between the double eye beam 10 and the horizontal reinforcing member 20. .

In addition, as shown in FIG. 7, a double eye beam type pile 100 may be manufactured by further combining a vertical resistance reinforcement pile 40 that is inserted into the trench ground G2 to the horizontal reinforcement member 20.

Here, the above-described vertical resistance reinforcement pile 40 is to be coupled in the state of advancing the vertical resistance reinforcement pile 40 to the ground (G2) to break before coupling the horizontal reinforcement member 20 to the double eye beam (10). Alternatively, as shown in FIG. 8, after the horizontal reinforcement member 20 is coupled to the double eye beam 10, the vertical resistance reinforcement pile 40 is inserted into a position adjacent to the horizontal reinforcement member 20, and then the horizontal reinforcement member 20 And fastening means (not shown in the drawings) or welding.

la. Earth plate installation steps

This step is a step of installing the earth plate (P) between the double eye beam type file 100 produced in the step of manufacturing the self-supporting mudguard as shown in FIG.

For this step, the partial and full digging work must be done at the same time, and although not shown in the drawing, the construction can be completed by proceeding with the process of installing the girdle and the trust.

On the other hand, looking at the operation of the present invention,

The present invention is a double eye beam consisting of a third and fourth plate (13, 14) is coupled between the first and second plates (11, 12) as a retaining construction method using the double eye beam type file 100 (10).

Therefore, even when the land boundary line is insufficient, since the cross section coefficient is higher than the existing H beam, it has excellent torsional strength and buckling strength, so that deformation due to earth pressure does not occur, so it is possible to enter into deeper depths, thus digging deeper. You can get the possible effect.

On the other hand, the double eye beam 10 forms a partial excavation part E after being approached to the ground G1 during the construction of the mud.

Here, after the partial excavation as described above, the double eye beam 10 is exposed to the outside from the ground (G1) to the ground (G2) as shown in Figure 10 (A1), and the ground (G2) At the lower end of the double eye beam 10, it is made of a non-exposed section (A2), which is near to the position where the lower end is formed, and in the case of the exposure section (A1), the double eye beam (10) changes the volume of soil in the backfill. Due to the expansion, the main earth pressure (Acive earth preussure) is generated based on the ground (G2) of the trench, and the passive earth pressure (A2) is generated in the non-exposed section (A2).

In the present invention, the manual earth pressure corresponding to the above main earth pressure by the double eye beam type pile 100 combining the horizontal reinforcement member 20 to the double eye beam 10 exposed after construction for the trench space O Even if the length of the non-exposed section A2, which is a near position for formation, is short, the exposed section A1 of the double eye beam 10 can form a supporting force capable of sufficiently coping with the main earth pressure, while the double eye beam 10 is formed. It is possible to obtain an effect that can prevent deformation.

That is, when the main earth pressure generated as shown in FIG. 10 is generated, the force corresponds only to the passive earth pressure generated in the non-exposed section (A2), which is the near position, but in the normal case, the non-exposed section (which is near the exposed section (A1)) The ratio of A2) should be 1: 1.5 ∼ 2.5, so if the depth of the trench is to be deeply formed, the non-exposed section (A2) should also be relatively deeper. It is difficult to form the phosphorus non-exposed section (A2) deeper, so it is difficult to form the depth of the trench.

Accordingly, the present invention is a horizontal reinforcing member 20 disposed to contact the ground (G2) of the trench is combined in an extended form in a direction capable of resisting the main earth pressure generated from the double eye beam 10 double eye beam When the main earth pressure occurs in (10), the reaction force (①) in the horizontal reinforcement member (20) occurs to support the double eye beam (10), so the size of the manual earth pressure, that is, the exposure section of the double eye beam (10) (A1) ) Even if the length of the non-exposed section A2 near the entrance is short, it is possible to obtain an effect that enables the construction of a trench to a deep depth by the support force of the horizontal reinforcement member 20.

In particular, by the action of the horizontal reinforcing member 20, even if there is no existing raker or earth anchor, a sufficient supporting force is formed, so that it is possible to obtain an effect that enables construction to be dug to a deep depth.

In addition, the above-mentioned support force acts to prevent the double eye beam 10 from being deformed by the main earth pressure.

Meanwhile, the double eye beam type file 100 according to the present invention further includes an inclined reinforcement member 30 for connecting the double eye beam 10 and the horizontal reinforcing member 20.

The inclined reinforcing member 30 has an additional supporting force in addition to the force supporting the double eye beam 10 by the horizontal reinforcing member 20, and further, the position different from the horizontal reinforcing member 20 as shown in FIG. Since the reaction force (②) in supports the double eye beam 10, it is possible to obtain an effect capable of preventing structural deformation of the double eye beam 10 due to the main pressure as well as the supporting force.

In particular, the inclined reinforcing member 30 as described above is composed of a structure that connects the double eye beam 10 and the horizontal reinforcing member 20, so that even if it is formed smaller than the size of a conventional raker, it forms a sufficient additional supporting force, thereby building walls. B. When constructing the foundation for the floor, it is possible to secure enough work space.

Further, in the double eye beam type pile 100 according to the present invention, a vertical resistance reinforcement pile 40 may be further formed on a lower side of the opposite side of the horizontal reinforcing member 20 combined with the double eye beam 10.

The vertical resistance reinforcement pile 40 is a configuration that is inserted in the downward direction from the trench ground (G2), the reaction force (③) in the vertical resistance reinforcement pile 40 supports the horizontal reinforcement member 20 as shown in FIG. Because of this, it is possible to obtain the effect of the double pile, as well as to increase the supporting force even when the ground is soft, so that it is possible to perform digging at a deep depth during the construction of the mud.

Although the above-described embodiment is described with respect to the most preferred example of the present invention, it is not limited to the above-described embodiment, and various modifications are possible without departing from the technical spirit of the present invention. It is obvious to the engineers.
