Abstract

PURPOSE:To facilitate the execution of construction by placing concrete blocks parallel on a base plate, placing thereafter another block parallelly on said blocks so that a retaining wall is formed on the front side of the blocks and earth pressure receiving steps are formed on the rear side of the blocks. CONSTITUTION:A plurality of concrete blocks (a) are placed parallel and concrete is filled into a space 5 between a front wall 2 and a rear wall 5 of concrete blocks (a) to form a concrete block row (a). Thereafter, concrete blocks (b) are placed parallel on the row (a) to form a concrete block row (b) and the rows (a) and (b) are combined integrally with each other by means of through holes 4 of a base plate 1, after which block rows C and D are piled up successively to form a retaining wall 6, while earth pressure receiving steps 7 are formed on the rear side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for forming a concrete block retaining wall of a weight-adding type that is large, tall, and capable of withstanding strong soil loads.

[Problems to be solved by conventional technology and invention]

Recently, large retaining wall blocks have come into widespread use,
The larger the size, the greater the strength required.

If the wall thickness is increased to meet the required strength, it will inevitably become very heavy, making it difficult to carry and handle, making construction that much more difficult.

The present invention provides a method for forming a weight-adding type concrete block retaining wall that solves this problem.

[Means to solve the problem]

The present invention will now be described in detail with reference to the accompanying drawings.

The front wall 2 is placed on the front part of the base plate 1, and the base plate 1 is placed behind the front wall 2.
A rear wall 3 is erected in the middle, and a base plate 1 is installed between the front wall 1 and the rear wall 3.
Concrete blocks a having through-holes 4 formed therein are arranged side by side, and the weight is reduced by pouring concrete into the space 5 between the front wall 2 and rear wall 3 of the concrete blocks a, or by filling the space with stone blocks, etc. Added concrete block 8
Form a row of concrete blocks, and place 1 base plate on 8 rows of concrete blocks.
concrete block b is placed across the front wall 2 and rear wall 3 of the lower concrete block a, and the front wall 2 and rear wall 3 are erected in the same manner as above, and the through hole 4 is bored. Eight rows of concrete blocks are arranged in parallel, and weight is added between the front and rear walls of this concrete block b in the same manner as described above to form five rows of concrete blocks.
A concrete block retaining wall that can withstand strong earth pressure is constructed by connecting the upper and lower parts together through a concrete block, stacking multiple levels to form a tall stacked retaining wall 6 on the front side, and forming a stepped earth pressure receiving part 7 on the rear side. This invention relates to a method for forming a concrete block retaining wall using a weight-adding method, which is characterized by forming a wall.

[For production]

A foundation is made on site, concrete blocks a molded in a factory are placed side by side on the foundation 8, and concrete is poured into the space 5 between the front wall 2 and the rear wall 3, or stone blocks or the like are filled.

Concrete block b is placed and placed on top of it, and weight is added in the same way.

Repeat this to move to row C of concrete blocks.

When six rows of concrete blocks are stacked up in the desired number of stages, the upper and lower concrete blocks are joined together by the through-holes 4, and a stacked retaining wall 6 is erected on the front side, and a step-shaped earthwork is built on the rear side. A pressure receiving portion 7 is formed, and due to the presence of this upper pressure receiving portion 7, a large weighted concrete block retaining wall that can withstand strong earth pressure is completed.

〔Example〕

FIG. 2 shows the case where the devices are arranged in a staggered manner, and FIG. 3 shows the case where they are arranged in parallel in the vertical and horizontal directions.

One large through hole 4 or several small through holes 4 may be provided in the base plate 1.

Although the drawing shows a U-shaped groove type without a side wall, it may be formed into a type with a side wall provided with a through window hole 4.

It is preferable that the base plate 1 is provided with uneven engagement steps 9 and 10 that engage with the tops of the lower front wall 2 and middle wall 3.

For the lowest concrete block a, the base plate 1 behind the rear wall 3 may be cut as shown in Figure 1, or the base plate 1 may be cut out as shown in Figure 1.
It is not necessary to provide the through window hole 4.

Although the drawing shows six stacked stacks, it is also possible to stack as few as two stacks or three stacks.

When connecting adjacent side walls, a bolt/nut method is preferable.

〔Effect of the invention〕

The present invention mass-produces concrete block bodies by mold production in a factory, transports them to the site, sets them side by side, and pours concrete to form a completed concrete block body.
Since the space is rectangular, it is possible to pull out the mold upwards, making it easy to produce the mold in a factory.

Concrete was then poured on site to form rows of heavy concrete blocks for each level, and the upper and lower levels were integrated through through holes in the base plate, and concrete was poured between the front and rear walls and blocks of stone were filled. Because the weight is added by adding weight by using a retaining wall or a combination of these, it becomes a stable large retaining wall with a large step-like earth pressure receiving part in the depth from the top and bottom with a high stacked retaining wall, which is sufficient to withstand strong earth pressure. This is a method for forming a sturdy concrete block retaining wall that can withstand weight addition.
