Description

ASSEMBLY FOR RETAINING WALL METHOD OF CONSTRUCTION}

The present invention relates to an assembly for a retaining wall construction method, and more particularly, to an assembly for a retaining wall construction method that can minimize the behavior of the ground by reinforcing between the wall of the ground and the earth plate when the ground is attached.

Generally, the basement is excavated for the construction and repair of the structure. Underground excavation method for excavating the underground is used according to the shape of the excavation surface in accordance with the geological characteristics, surrounding structures, construction period and construction cost, the open cut and the open-cut method using the earth wall.

Here, the earthquake wall method is used when the structure is located around the slope or the ground conditions are difficult to apply the slope opening method, the wall of the earthquake method (h-pile) and earth plate is used.

On the other hand, the earthquake wall method is to install the soil plate between the H pile by inserting the H pile into the ground by drilling or pile drilling. Here, the space between the earth plate and the ground is backfilled with soil.

However, there is a problem in that the space between the earth plate and the ground is narrow so that the compaction of soil which is backfilled is not sufficient.

In addition, if there is not enough compaction of soil backfilled between the earth plate and the ground, the ground behavior due to the ground relaxation and the outflow of soil backfilled during the rainy season may cause settlement on the back of the wall of the soil wall, and thus the back of the soil film. It may pose a risk to the stability of the structure.

The problem to be solved in the problem of the background art is to provide an earthquake wall assembly that can reinforce between the earth plate and the ground to minimize the ground behavior due to stress relaxation during ground excavation.

In addition, by using a reinforcing agent that can replace the soil reinforcement between the earth plate and the ground to provide an earthquake wall assembly that can prevent the soil leakage that may occur during the rainy season.

According to the present invention, the solution for solving the problem is, in the assembly for the wall construction method used for the attachment of the ground, the h-pile is inserted perpendicular to the ground of the ground, arranged in a plurality at a predetermined interval (h- pile); A plurality of earth plates stacked between a pair of said H pile; Interposed between the rear surface of the earth plate and the wall of the ground, it is achieved by the assembly for the mud wall construction method comprising a reinforcement pack which is injected into the reinforcement for reinforcing between the earth plate and the wall of the ground.

The reinforcing agent may include cement milk.

The reinforcement pack may include a reinforcement pack body having an accommodating space for accommodating the reinforcement, an injection hose and a discharge hose formed with an injection port and a discharge hole through which the reinforcement is injected and discharged into the reinforcement pack body, and the reinforcement pack. It may include a support ring for supporting the wall of the ground.

And, the receiving space of the reinforcement pack body is partitioned at regular intervals, characterized in that the receiving space partitioned at regular intervals are in communication with each other so that the reinforcing agent is injected.

Therefore, according to the solution of the above problem, by placing a reinforcement pack that can reinforce between the earth plate and the ground can minimize the ground behavior due to stress relaxation during the ground excavation, thereby improving the reliability of the wall An assembly for the cladding wall method is provided.

In addition, by replacing the soil reinforcement between the earth plate and the ground with a reinforcement pack, there is provided an assembly for the wall construction method that can prevent the outflow of soil that may occur during the rainy season.

Hereinafter, with reference to the accompanying drawings will be described in detail for the assembly wall construction method according to the present invention.

1 is a perspective view of the earth wall assembly assembly according to the present invention installed on the ground, Figure 2 is a perspective view of the reinforcement pack area of the earth wall assembly assembly shown in FIG.

As shown in these figures, the assembly wall construction method 1 according to the present invention is a h-pile (3) which is inserted perpendicular to the ground of the ground 100 and a pair of H-pile A plurality of earth plate 5 laminated between (3) and the reinforcement pack 10 interposed between the back surface of the earth plate 5 and the wall of the ground 100 is included.

The H pile 3 is generally made of metal steel. The H pile 3 is inserted perpendicular to the ground of the ground 100. The H pile 3 is inserted perpendicularly to the ground of the ground 100 in plural along the wall of the ground 100. Here, the H pile 3 has a 'H' shape cross section. A plurality of earth plates 5 are stacked between the H piles 3 inserted into the ground of the ground 100 in plurality.

The earth plate 5 is stacked in plural numbers between the H piles 3 to form a wall together with the H pile 3. The earth plate 5 is made of various materials such as plank-shaped wood or plastic.

Next, as shown in FIGS. 3 to 5, the reinforcement pack 10 includes a reinforcement pack main body 20 in which an accommodating space for accommodating the reinforcement is formed, and an injection hole through which the reinforcement is injected and discharged into the reinforcement pack main body 20 ( 52 and the injection hose 50 and the discharge hose 60, the discharge port 62 is formed, and a support ring 80 for supporting the reinforcement pack 10 on the wall of the ground (100). The reinforcement pack 10 is interposed between the rear surface of the earth plate 5 and the wall of the ground 100, and a reinforcement for reinforcing between the earth plate 5 and the wall of the ground 100 is injected.

Here, the reinforcing agent, as an example of the present invention uses cement milk. The reinforcing agent used in the present invention is cured to have a strength capable of reinforcing between the earth plate 5 and the walls of the ground 100 after one day after injection into the reinforcement pack 10. And, the reinforcing agent has a higher strength after a time exceeding one day after being injected into the reinforcing pack 10.

The reinforcement pack body 20 forms the appearance of the reinforcement pack 10. The reinforcement pack body 20 is interposed between the earth plate 5 and the wall of the ground 100 and receives reinforcement from the outside. Reinforcement pack body 20 is an example of the present invention, is provided with a non-woven material so that the moisture contained in the reinforcement is discharged to the outside while the reinforcement injected from the outside is cured. The interior of the reinforcement pack body 20 is an example of the present invention, is divided by the partition portion 30 in two parts parallel to the ground of the ground (100). That is, the inside of the reinforcement pack main body 20 has a three-part area into which the reinforcing agent is injected as a whole by the partition part 30 of the two parts. The reason for dividing the area by using the partition 30 inside the reinforcement pack main body 20 is that when the reinforcement is injected and cured, the curing time can be reduced and the required strength can be secured. Here, the partition 30 partitioning the reinforcement pack body 20 is in communication with each other so that the reinforcing agent flowing from the lower portion of the reinforcement pack body 20 can be introduced.

The injection hose 50 is disposed below the reinforcement pack body 20. The injection hose 50 is divided into a portion inserted into the reinforcement pack body 20 and a portion exposed to the outside of the reinforcement pack body 20. In the injection hose 50, a plurality of supply holes 54 for discharging the reinforcing agent injected into the injection hose 50 are disposed at regular intervals such that the reinforcing agent injected from the outside flows into the reinforcement pack body 20. Here, after the reinforcement pack body 20 is supported on the wall of the ground 100, the reinforcement is injected into the injection hose 50 by connecting the injection hose 50 and the reinforcement supply unit (not shown) exposed to the outside. In the process of injecting the reinforcing agent into the injection hose 50, the reinforcing agent is first injected at low pressure, and the reinforcing agent is sufficiently accommodated in the reinforcing pack body 20, and then pressurized at high pressure. The process of injecting the reinforcing agent into the injection hose 50 will be described in detail in the operation process to be described later.

On the other hand, the discharge hose 60 is provided on the upper side of the side opposite to the injection hose 50 disposed in the lower portion of the reinforcement pack body (20). The discharge hose 60 is formed with a discharge port 62 for discharging the reinforcing agent from the inside of the reinforcement pack main body 20 to the outside. Here, the role of the discharge hose 60 is to confirm that the reinforcement is sufficiently injected into the reinforcement pack body 20. For example, when the reinforcing agent is discharged into the discharge hose 60 while injecting the reinforcing agent into the injection hose 50, it is determined that sufficient reinforcing agent is injected into the reinforcement pack body 20.

The support ring 80 is provided at the top of the reinforcement pack body 20. Support ring 80 is an example of the present invention, two are provided at regular intervals. The support ring 80 supports the reinforcement pack body 20 on the wall of the ground 100. Here, the support ring 80 is penetrated by a support member (not shown) such as an iron nail to be supported on the wall of the ground 100.

Looking at the installation process and the operation process of the assembly wall construction method 1 according to the present invention by such a configuration as follows.

First, when the ground 100 starts to be attached, the wall assembly of the earthquake wall construction method 1 is installed so that the wall of the ground 100 does not collapse.

A plurality of H piles 3 are inserted at regular intervals along the wall of the ground 100 with respect to the ground of the ground 100. Then, the reinforcement pack 10 is installed on the wall of the ground 100 so as to be supported by the wall of the ground 100 through the support ring 80 as a support member.

After the H-pile 3 and the reinforcement pack 10 are installed, the plurality of H-piles 3 inserted perpendicularly to the ground of the ground 100 in the transverse direction of the insertion direction of the H-pile 3. The earth plate 5 is laminated.

When a predetermined number of earth plate 5 is laminated between the H pile (3) connects the injection hose 50 provided in the reinforcement pack 10 and the reinforcing agent supply unit for supplying the reinforcing agent. When the reinforcing agent is injected through the injection hose 50, the reinforcing agent flows into the reinforcement pack body 20 through the supply port 54 of the injection hose 50 disposed inside the reinforcement pack body 20.

At this time, since the reinforcement pack main body 20 is partitioned into the partition part 30, the reinforcement agent is filled from the lower part of the reinforcement pack main body 20 to the upper part. If the reinforcement is discharged into the discharge hose 60 while the reinforcement is continuously injected into the injection hose 50, the reinforcement is stopped by determining that the reinforcement is sufficiently filled in the reinforcement pack main body 20.

Here, in the process of injecting the reinforcing agent into the injection hose 50, the reinforcing agent is first injected into the reinforcement pack body 20 by injecting the reinforcing agent at low pressure, and then the reinforcing agent is discharged to the discharge hose 60 in the subsequent reinforcing agent injection process. If possible, the discharge hose 60 is closed and pressurized at a higher pressure than the initial injection process.

Then, the moisture contained in the reinforcement contained in the reinforcement pack main body 20 is allowed to flow out of the reinforcement pack main body 20 made of the nonwoven fabric material, thereby increasing the curing and strength of the reinforcement.

Accordingly, by arranging a reinforcement pack that can reinforce between the earth plate and the ground, it is possible to minimize the ground behavior due to the stress relaxation during the ground excavation, thereby improving the reliability of the retaining wall.

In addition, by replacing the soil reinforcement between the soil plate and the ground with a reinforcement pack, it is possible to prevent the outflow of soil that may occur during the rainy season.
