Top-down construction methods are actively used as a method of constructing a wall in the ground and constructing an architectural structure based on the wall.

This is accomplished by forming an underground wall (earth retaining wall) as a hypothetical structure by cast in place pile (CIP) method, a soil cement wall (SCW) method, and forming a wall , And a method of constructing a building structure by forming a column or a bearing wall on the main wall is adopted.

That is, the ground is pierced along the excavation area, and a reinforcing material such as a reinforcing net or H-file is inserted into the perforation hole, and then a concrete (cement concrete or soil concrete) is placed to form a wall.

And, after curing of reinforced concrete, earth pressure support by soil wall is most important until the strength is developed, so reinforcements are assembled in the field to reinforce the wall.

Specifically, a cast in place pile (CIP) method is a type of drilling punch that is formed by drilling a predetermined diameter and then forming concrete walls by injection concrete.

This is because it has the advantage of excellent strength because it forms the main heating type rigid body. However, it has a disadvantage that the joint part is poor due to each separated column, and the displacement is generated, have.

On the other hand, the S.C.W. (soil cement wall) method is a method of forming a wall by forming a wall by injecting injecting agent after perforating to the depth of plan with a main heating type underground wall, and inserting H file into a stress material.

This has the disadvantage that the strength effect is lowered while the degree effect is better, while the strength is lowered.

In addition, since the conventional underground wall method only functions as a hypothetical wall, a different order method is required due to a disadvantage of the order, and when the groundwater level is high in the field condition, or when the degree of depth is deepened by heaving or boiling in rainy season, It is necessary to apply enough toilets to prevent the leakage of fine particles.

Therefore, it is common to deeply construct the root to ensure that the entire bottom of the earth wall penetrates to the rocky region.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 and subsequent drawings, the first embodiment of the wall member 100 proposed in the present invention includes a main body 110 of a rectangular box structure having upper and lower trim portions; A plurality of partition walls 120 formed in the body 110 to have a lattice structure; Wherein the upper flange 141 and the lower flange 142 of the H file 140 extend in the longitudinal direction on the front surface and the rear surface of the partition wall 120, respectively, And the near entry length L2 of the H file 140 is longer than the near entry length L1 of the plurality of partitions 120 (FIG. 1).

That is, in the conventional ground wall construction method, when the groundwater level is high or the depth of water is deep, the entire lower end of the soil wall is inserted deep into the rocky region, whereas in the present invention, the wall member 100, Only the H file 140 coupled to the other side of the wall member 100 is inserted into the rocky region.

In other words, the H file 140 of the present invention has a function of reinforcing the wall member 100 in the case where the groundwater level is high or the degree of depth is deep, and at the same time, it has a function of ensuring a sufficient penetration stability.

In addition, by shortening the root of the entire wall member 100 through the combination of the H file 140 having a relatively long root length L2 and the plurality of partition walls 120 having a short root length L1, So that the plurality of partition walls 120 are not completely inserted into the rocky zone but only the H file 140 is inserted into the rocky region, thereby improving workability and economical efficiency.

Such a wall member 100 secures the stability of the earth wall during construction and improves the stability of the structural wall after the construction so that excessive earth pressure can be generated due to rainstorm and groundwater rise, The lateral displacement of the wall is minimized and the water flowability is maximized by effectively responding to the respective ball displacements caused by the outflow of the particles.

3, the wall member 100 of the present invention is constructed such that one side of the other adjacent wall member 100b is connected to the H file 140 by the H file 140 being coupled to the other side of the main body 110. [ The upper flange 141 and the lower flange 142 of the upper flange 141 and the lower flange 142 (Figs.

Therefore, the H file 140 also serves as a coupling member for coupling the plurality of wall members 100 and 100b, and this coupling is very simple and robust.

The wall member 100 of the present invention is characterized in that the gap between the barrier rib 120 and the reinforcing bar 133 can be ensured through the structure in which the guide member 130 is provided on the inner surface of the barrier rib 120. [

The upper guide member 130 includes a tubular member 131 to which the reinforcing bar 133 is inserted and a tubular member 131 which is formed on the inner side of the tubular member 131 and the partition wall 120 or between the tubular member 131 and the partition 120 And a spacing member 132 which is coupled to the inner rear surface to maintain mutual spacing.

That is, in the conventional underground wall construction method, it is difficult to secure the space between the wall and the reinforcing bars, and the reinforcing bars may be separated, so that the reinforcing effect of the walls of the reinforcing bars is significantly lowered. However, The gap between the inner surface of the wall member 100 and the reinforcing bar 133 can be maintained to reliably prevent such a problem.

Since the interval between the partition wall 120 and the reinforcing bar 133 is permanently ensured through the spacing member 132, the reinforcing effect by the reinforcing bar 133 can be enhanced to maximize the strength of the wall, The effect of preventing the occurrence of displacement can be obtained.

In addition, there is an advantage that it is possible to further improve the water repellency and waterproofness of the wall by preventing the occurrence of displacement in the wall.

In addition, the wall member 100 of the present invention is formed of an iron plate structure, and is stable in penetration into the ground, and is excellent in durability and structural stability.

Since the wall member 100 is formed of an iron plate structure and excellent strength and structural stability can be ensured by providing the H file 140 and the guide member 130, the wall member 100 has the following advantages.

That is, after the finishing wall body 400 is formed on the entire surface of the underground wall body 200 formed by pouring the concrete into the wall member 100, the integrated structure of the underground wall body 200 and the finishing wall body 400 is implemented, It can be used as a permanent wall (Figs. 14 and 15).

In other words, conventionally, since the underground wall can not permanently exhibit its function as a wall due to the above problems, it is used only as a hypothetical example during construction, and a finished wall, that is, a wall formed at the front of the underground wall is permanently used.

In other words, since the underground wall and the finishing wall must be double-constructed, the cross-sectional area is increased, resulting in an economical cost and a long construction period.

However, since the wall member 100 of the present invention can permanently secure excellent strength and structural stability, it can be used as a soil facility during construction and can exhibit the function of the main structural wall even after construction.

Therefore, the underground wall body 200 using the wall member 100 of the present invention and the finishing wall body 400 provided on the front surface thereof can be integrated and used as a permanent wall body.

As a result, it is possible to reduce the required section of the wall to improve the economical efficiency, shorten the construction period, and maximize the strength of the wall.

The wall member 100 according to the present invention may have a structure in which the guide member 130 is installed before the guide member 130 and the guide member 130 and the reinforcing bar 133 Since it is designed with the installed structure and is manufactured in the factory, all the processes are completed by simply pouring concrete after entering the site.

Therefore, there is an advantage that the operation is very simple.

Specifically, the main body 110 is inserted between the upper flange 141a and the lower flange 142a of the H-file 140a coupled to the other side of the adjacent wall member 100a, And is formed so as to have a narrower width toward the side (FIG. 4).

That is, one or both of the front surface and the rear surface of the main body 110 is inclined inward, and the upper flange 141a and the lower flange 141b of the H file 140a coupled to the other side of the adjacent wall member 100a 142a.

Particularly, it is structurally preferable that the front surface of the main body 110 is formed so as to be inclined inward.

Since the front surface of the upper flange 141a of the H file 140a coupled to the front surface of the main body 110 and the other side of the adjacent wall member 100a is flat in this structure, There is an advantage that it is easy.

In addition, when the coating type index material 170 is applied to the joint surface between the main body 110 and the adjacent H file 140a, the coupling becomes more robust (FIG. 3).

After the underground wall 200 and the finishing wall 400 of the present invention are installed, the underground wall 200 has a shear reinforcement function in common. The H file 140 installed in the wall member 100 and the reinforcement The reinforcing bars 133 function as a bending member of the finishing wall body 400, so that excellent structural stability can be secured.

More specifically, it is preferable that a plurality of the guide members 130 are provided on the inner surface of the partition 120 with an interval in the height direction and the width direction.

In the case of a structure in which the guide member 130 is not formed, when the reinforcing steel bar 133 is inserted along the height direction of the wall member 100 and the guide member 130 is formed, The reinforcing steel bar 133 is inserted along the height direction of the wall member 100 or the reinforcing bar 133 is installed in advance to form the underground wall member 200 by pouring concrete into the wall member 100. [

The construction method of the underground wall body proposed in the present invention is constituted by the following process.

A drilling step is first performed to form a plurality of perforation holes 10 (Fig. 9).

A wall member inserting step of inserting the wall member 100 of the present invention along the longitudinal direction of the plurality of perforation holes 10 is performed after grouting inside the plurality of perforation holes 10 (FIG. 10).

The wall member 100 is manufactured in the factory with the H file 140 coupled to the other side of the main body 110, so that the wall member 100 is inserted in the site.

It is also characterized in that the near entry (L2) of the H file (140) is installed so as to be deeper than the near entry (L1) of the plurality of partitions (120).

As a result, only the H file 140 is inserted into the rocky region, thereby ensuring sufficient stability and soil stability.

Specifically, in the step of inserting the wall member, first, a wall member inserting step of inserting the wall member 100 having the H file 140 coupled to the other side of the main body 110 into the perforation hole 10 is performed.

One side of the main body 110 is inserted and coupled between the upper flange 141a and the lower flange 142a of the H file 140a coupled to the other side of the adjacent wall member 100a, An adjacent wall member insertion step of inserting the adjacent wall member 100a is performed.

In addition, when the guide member 130 is installed on the inner surface of the partition 120 and is manufactured at a factory, the reinforcing bar 133 is only inserted into the tubular member 131 before and after insertion in the field, There is an advantage that it is very easy.

In addition, when the guide member 130 and the reinforcing bar 133 are installed in advance, since the concrete member is laid only after the wall member 100 is inserted, the workability can be maximized.

Next, an underground wall forming step is performed in which concrete is installed in the inside of the wall member 100 to form a ground wall member 200 (FIG. 12).

The present invention is characterized in that it forms an integrated structure of the finishing wall body 400 installed in front of the underground wall body 200 and the underground wall body 200 and can be used as a whole permanent wall body.

In the forming step of the finishing wall body 400, first, after the above-mentioned in-wall wall forming step, a crushing step is performed to sweep the front region of the underground wall 200.

A step of joining the reinforcing bar assembly 310 and the connecting member 320 is performed after the connecting member 320 is installed on the exposed surface of the ground wall 200.

Then, a finishing wall forming step for forming the finishing wall body 400 by pouring concrete so as to fill the reinforcing steel assembly 310 is performed.

As a result, the strength of the permanent wall can be secured with excellent unity through the integrated structure of the underground wall body 200 and the finishing wall body 400 of the present invention, and the required cross section of the wall can be reduced, (Fig. 14).

Here, it is structurally preferable that the connecting member 320 uses a stud.

It is effective that the studs are mounted by welding, and the wall member 100 of the present invention is formed of an iron plate structure, so that the mounting of the studs is facilitated.

The wall member 100 of the present invention can be implemented with the structure of the second embodiment as follows.

As shown in FIG. 5, a main body 110 of a rectangular box structure having upper and lower trim portions; And a plurality of partitions 120 formed in the main body 110 so as to have a lattice structure in which the main body 110 has one side joined to the upper flange 141 and the lower flange 142 of the H- The main body 110 is formed such that the end face of the main body 110 is narrowed toward one side and the other side is joined between the upper flange 141b and the lower flange 142b of the other adjacent H files 140b, ) Is formed so as to be narrowed toward the other side (FIG. 5).

That is, unlike the structure of the first embodiment described above, the wall member 100 according to the second embodiment is manufactured in a state in which the wall member 100 and the H file 140 are not coupled to each other, Respectively, and then mutually coupled.

Here, as in the structure of the first embodiment, the H file 140 penetrates to the rocky region, thereby securing sufficient stability, securing the stability of the earth wall during construction, and improving the stability of the structural wall after construction.

In addition, the near entry length L2 of the H file 140 is longer than the near entry length L1 of the plurality of partitions 120 (FIG. 1).

Therefore, the lower end of the entire wall member 100 does not extend to the rocky region during installation, and only the H-file 140 reaches the rocky region, thereby improving economic efficiency and workability.

Specifically, the wall member 100 is formed so that the width of the end face of the main body 110 becomes narrower toward one side and the other side, in order for both side faces to be coupled with the H file 140 and the other adjacent H files 140b, respectively (Fig. 7).

Here, it is preferable that one or both of the front surface and the rear surface of the main body 110 are formed so as to be inclined inward (Figs. 5 and 8).

Further, it is structurally preferable that the front surface of the main body 110 is formed so as to be inclined inward.

This structure allows the front surface of the upper flange 141 of the H file 140 and the front surface of the other side H file 140b of the other side of the main body 110 to be flush with the front surface of one side of the main body 110, (FIG. 6), which makes it easier to work on the front surface of the apparatus 100 (FIG. 6).

The same effect as that described above can be obtained by providing the guide member 130 on the inner surface of the partition wall 120 also in the wall member 100 according to the second embodiment as in the structure of the first embodiment.

Next, the underground wall body 200 using the wall member 100 according to the second embodiment of the present invention will be described.

The H file 140 is coupled between the wall member 100 and the adjacent wall member 100a of the present invention and the reinforcing bar 133 is inserted along the height direction of the wall member 100 and the adjacent wall member 100a In addition, concrete is installed in the interior to form the underground wall body 200.

The construction method of the underground wall 200 is the same as the construction method of the underground wall 200 using the wall member 100 of the first embodiment.

In particular, in the wall member and H file insertion step, an H file insertion step of inserting the H file 140 into the perforation hole 10 is performed (FIG. 9).

Thereafter, one side of the main body 110 is inserted and coupled between the upper flange 141 and the lower flange 142 of the H file 140, and the other side of the H file 140 100 are inserted into the wall member insertion step.

The other side of the adjacent main body 110a is inserted between and joined to the upper flange 141 and the lower flange 142 of the H file 140, 100a are inserted into the adjacent wall member insertion step (FIG. 11).

Also, between the wall member inserting step and the ground wall forming step, it is preferable that the inner grout removal and cleaning step of the wall member 100 is performed.

The connecting member 320 is installed on the front surface of the exposed underground wall 200 and the reinforcing bar assembly 310 and the connecting member 330 320, and then the concrete is poured to form the finishing wall body 400 so that the reinforcing steel assembly 310 is embedded (FIG. 13).

In the underground wall forming step, an outer grouting step may be performed to grout a region between the plurality of perforation holes 10 and the wall member 100.

As the curing is completed through the outer grouting step, the coating effect of the main body 110 can prevent corrosion of the wall member 100 and improve the structural performance, water repellency and waterproofing.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
