Description

Concrete retaining wall construction method using mixed blocks of self-supporting fill blocks and hollow blocks}

The present invention relates to a method of constructing a concrete retaining wall using a mixed block of self-supporting fill blocks and hollow blocks. More specifically, filling holes and through holes are formed inside the hollow blocks and filling blocks forming the retaining wall, and construction In the process, the bearing capacity is improved by filling only the filling holes of the filling blocks that support the reinforcing layer, making the blocks lighter and easier to transport and store, and the through-holes of the hollow blocks that do not support the reinforcing layer are not filled with filler, thus reducing construction time. It relates to a construction method for a concrete retaining wall using a mixed block of self-supporting filled blocks and hollow blocks, which can shorten the block and reduce the manufacturing cost of the block.

In general, if left unattended, slopes such as cutouts, sloping walls, and slopes formed in newly built apartments, housing complexes, or roadsides have the risk of collapsing due to rain or earthquakes, causing secondary damage. In order to prevent soil collapse, separate civil engineering structures such as retaining walls are being constructed.

This retaining wall structure is a wall structure that resists earth pressure and prevents the soil behind it from collapsing, and is installed to prevent ground collapse that occurs when the ground surface is steeper than the stable slope angle (angle of repose).

Such a retaining wall structure is conventionally made by stacking concrete blocks in multiple stages or pouring concrete. Such a retaining wall is made up of a vertical wall constructed vertically at a certain height from the ground and backfill soil filled at the rear.

However, the concrete blocks used in conventional retaining wall structures are made of concrete and have a filled block structure, so they are difficult to transport and store due to their weight, and are placed on the upper part of the retaining wall structure that does not support backfill soil. Since concrete blocks are also formed as filled blocks, there is a problem that construction costs and construction time increase, and there is a problem that safety accidents can occur in the process of moving heavy filled blocks to the top.

The above-described invention refers to the background art of the technical field to which the present invention pertains, and does not mean prior art.

As shown in the drawing, the present invention's construction method of a concrete retaining wall using a mixed block of self-supporting fill blocks and hollow blocks (hereinafter referred to as 'retaining wall construction method' for convenience of explanation) is a method of constructing a concrete retaining wall using a mixture of self-supporting fill blocks and hollow blocks. As a construction method of a retaining wall installed to support a surface, the construction method of a retaining wall according to the present invention includes a ground leveling step (S1), a filling block wall forming step (S2), a hollow block wall forming step (S3), and filling space reinforcement soil. It consists of step S4.

The ground leveling step (S1) is a step of removing and leveling foreign substances on the ground where the retaining wall supporting the support surface is to be installed.

In the ground leveling step (S1), foreign substances on the ground where the wall is installed are removed and compacted with a roller to flatten the surface.

It is also possible to dig the ground where the wall is to be installed to a certain depth and then flatten it.

The filling block wall forming step (S2) is a step of forming a filling block wall (10) by stacking filling blocks (11) on the ground.

In the filling block wall forming step (S2), the filling block wall 10 is formed by filling the ground with filling blocks.

The filling blocks 11 are stacked in a lengthwise manner to form the filling block wall 10.

At this time, the filled block wall 10 is formed at a height corresponding to half of the height of the entire retaining wall, and the remaining half height can be formed as a hollow block 21 wall 20. .

Alternatively, the filling block 11 wall 10 is formed to a height at which the reinforced soil, which will be described later, is filled, to support the reinforced soil, and the hollow block wall 20 is formed in the portion where the reinforced soil is not filled. You can.

In other words, the hollow block 21 is formed in an area relatively less filled with reinforced soil than the filling block 11, so that the process of filling the inside of the hollow block with the filler 50 is unnecessary, thereby shortening the construction time. This can be done and construction costs can be reduced.

In addition, the filling hole 112 and the through hole 212 inside the hollow block 21 and the filling block 11 make it lighter than the block without the filling hole 112 and the through hole 212, allowing for transport and It makes storage easier and improves safety and work efficiency during the construction process.

The filling block 11 includes a filling block body 111 made of concrete, a filling hole 112 formed by connecting the upper and lower surfaces of the filling block body 111, and a filling block body 111. It may be made of a filler 50 filled in the formed filling hole 112.

At this time, the filler 50 may be made of soil or gravel.

In the filling block 11, a base finishing panel 30 is further fastened to the filling hole 112 of the filling block body 111, and the base finishing panel 30 is located on the lower side of the filling hole 112. It is arranged to support the filler 50 filled in the filling hole 112.

The base finishing panel 30 is made of synthetic resin or stone, is inserted into the lower side of the filling hole, and is then attached to the inner surface of the filling hole or fixed by screwing.

The base finishing panel 30 prevents the filler 50 from leaking out during the process of filling the filling hole 112, thereby enabling rapid and uniform filling.

In the filling hole 112, one end of support pins made of synthetic resin material is further screwed or attached to the inner surface to be fixed, so that the support pins are supported by being inserted into the filler 50 filled in the filling hole 112. , it is possible to improve the bearing capacity and prevent the filler 50 from being moved by external force.

The hollow block wall forming step (S3) is a step of forming a hollow block wall (20) by stacking hollow blocks on the upper part of the filling block (11) wall (10).

In the hollow block wall forming step (S3), hollow blocks 21 are stacked on the upper part of the filling block 11 wall 10 to form a hollow block wall 20.

The hollow blocks 21 are stacked in a lengthwise manner to form the hollow block wall 20.

The hollow block wall 20 is formed in a section (height) that does not support reinforced soil.

The hollow block 21 consists of a space block body 211 made of concrete, and a through hole 212 formed by connecting the upper and lower surfaces of the space block body 211.

In the hollow block 21, a top finishing panel 40 may be further fastened to the through hole 212 of the space block main body 211.

The top finishing panel 40 may be made of synthetic resin or stone.

After being fitted into the lower side of the through hole 212, it may be attached to the inner surface of the through hole 212 or fixed by screwing.

The top finishing panel 40 may be configured to block foreign substances or dirt from entering the upper part of the through hole 212.

By further forming rainwater holes in the top finishing panel 40 to discharge rainwater through the rainwater holes, it is possible to prevent rainwater from accumulating on the upper surface of the top finishing panel.

The filling space reinforcing soil filling step (S4) is a step of forming a reinforcing layer 300 by filling the filling space 200 formed between the filling block wall 10 and the support surface of the ground 100 with reinforcing soil.

The reinforcing soil filling step (S4) of the filling space 200 is performed by filling the reinforcing soil in the filling space 200 formed between the filling block 11 wall 10 and the supporting surface of the ground 100, and then filling the filled reinforcing foam with the reinforcing soil. The upper surface of can be compacted with a roller or compactor to form a reinforcement layer 300 to support the ground 100 and the support surface.

The upper end of the support shaft is screwed and fixed to the bottom of the top finishing panel 40, one end of the reinforcement shaft is screwed and fixed to the outer surface of the support shaft, and the other end of the reinforcement shaft is connected to the through hole 212. By screwing and fixing the inner surface of the top finish panel 40, the bottom surface of the top finish panel 40 can be supported to improve the bearing capacity, and the top finish panel 40 can be prevented from sagging or being damaged due to load or external force.

By further screwing and fixing a vibrator, which is a vibrator, to the inner surface of the filling hole 112, the vibration of the vibrator is transmitted to the filling block body 111 and the filling material 50, thereby forming the filling hole 112. ), the filling efficiency can be increased by reducing the voids in the filler (soil) filled in the area.

In the filling block body 111, a fastening block made of concrete is inserted into the filling hole 112 to improve the bearing capacity, thereby saving time compared to filling the filling hole 112 with a filler 50 made of soil. The time can be shortened, the filling block body 111 can be formed with a uniform weight, and the construction time can be shortened.

The fastening block is supported on the base finishing panel 30 when inserted into the filling hole 112, and can be fitted in the field.

The fastening block further has a tapered guide surface formed so that the outer surface tapers inward as the outer surface goes downward, thereby preventing the fastening block from becoming caught in the process of fitting into the filling hole 112.

An elastic buffer tube made of an elastic synthetic resin material is inserted into the filling hole 112 of the filling block body 111, and then the outer surface of the elastic buffer tube is attached and fixed to the inner surface of the filling hole 112, and the elastic buffer tube is fixed. By inserting the fastening block into the buffer pipe, the fastening block is supported by the elasticity of the elastic buffer pipe, preventing it from moving due to external force, and also preventing collision and friction with the inner surface of the filling groove. .

After the filling space reinforcing soil filling step (S4), the upper filling space 200 formed between the hollow block wall 20 and the supporting surface of the ground 100 is filled with reinforcing soil to form an upper reinforcing layer 300. An additional top filling space reinforcement soil filling step (S4-1) may be added.

That is, when filling the upper filling space 200 formed between the hollow block wall 20 and the support surface of the ground 100 with reinforced soil, the earth pressure received from the hollow block wall 20 is the filled block wall ( 10), it is possible to support the reinforcement layer 300 filled in the upper filling space 200.
