Abstract

PURPOSE:To improve the earth pressure resisting strength by forming box-form blocks furnishing wall holding surfaces, an intermediate wall, and the like, in several sorts of depth sizes, and after setting them step by step, filling a concrete or pebbles in the boxes and laminating those blocks. CONSTITUTION:On a foundation plate 1, a box form block furnishing a front wall 2, a rear wall 4, and side walls, which compose wall holding surfaces is provided, and an intermediate wall 3 is set at the position to hold the rear wall of a block laminated on the upper side on the first block. In the same structure, various sorts of blocks a, b,...e, and f whose depth sizes are different are formed. Then, while the blocks a, b,... are set step by step, a concrete, pebbles, or the like are filled in the blocks a, b,..., to add the weights to the blocks. Consequently, a retaining wall with a high earth pressure resisting strength can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for forming a concrete block retaining wall of a weight-adding type that is large and tall and can withstand strong earth pressure.

[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.

A front wall 2 is placed at the front of the base plate 1, a middle wall 3 is placed behind the front wall 2 at a position supporting the back wall 4 of the blocks to be stacked on the upper stage, and a predetermined area is attached from the middle wall 3 at the rear of the middle wall 3. Concrete blocks a with rear walls 4 erected at a weight addition interval l are placed side by side, and concrete is poured into the front space 5 and rear space 6 of the concrete blocks a, or blocks of stone are filled in and add weight to form 8 rows of concrete blocks, and on these 28 rows of concrete blocks, the front wall 2' overlaps with the front wall 2 of the concrete block a below, and the middle W, 3
Concrete block b, which has a depth such that the rear wall erected at the rear of ゛ by 4° is placed on the inner wall 3 of concrete block a below, is placed and placed in parallel, and weight is added in the same manner as described above to make concrete. 5 rows of blocks are formed, followed by row C of concrete blocks, and 6 rows of concrete blocks are piled up in multiple stages, each with added weight and stacked tall on the front wall 7
This relates to a method for forming a concrete block retaining wall using a weight addition method, characterized in that a step-like earth pressure receiving part 8 is formed on the rear side to form a concrete block retaining wall that can withstand strong earth pressure. It is.

A front wall 12 is erected on the front part of the base plate 11, and side walls 13 are erected on the left and right sides of the base plate 12 so as to be connected to the front wall 12. Concrete blocks (A) to which the rear closing plate 14 is removably fixed are arranged side by side, and weight is added by pouring concrete into the inside of this concrete block (A) or filling it with blocks of stone. , the front wall 12' is placed on this concrete block (A) row.
The left and right side walls 13' and rear wall 15' are respectively in front of the concrete block (a) below! ! 12. A concrete block without a base plate (b) provided in the shape of a rectangular cylinder with a subfloor that overlaps the side wall 13 and the rear closing plate 14 is placed and placed in parallel, and concrete is placed inside the concrete block without a base plate (b). Add weight by pouring concrete blocks or filling them with stone blocks, etc., and then pile up multiple rows of concrete blocks (8) whose depth gradually decreases according to the taper in the front and back, and add weight to each one to create a tall bottom. The present invention relates to a method for forming a concrete block retaining wall using a weight-adding method, which is characterized by forming a concrete block retaining wall that has a wide depth and can withstand strong earth pressure.

[For production]

The first invention will be explained.

A foundation is made on site, concrete blocks a made in a factory are placed side by side on the foundation 9, and concrete is poured into the front space 5 and the rear space 6, or concrete is filled with blocks of stone etc. Either pour it or fill it with stone blocks, concrete blocks, etc.

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 piled up, a stacked front wall 7 is erected on the front side, and a step-shaped earth pressure receiving part 8 is formed on the rear side. The concrete block retaining wall is completed.

The second invention will be explained.

Concrete blocks manufactured at the factory on foundation 9 (A)
are placed side by side, the rear closing plate 14 is fixed, and concrete is poured into the interior in the same manner as described above, or stone blocks or the like are filled and concrete is poured, or stone blocks or concrete blocks are filled. .

On top of that is a concrete block without a base plate (b).

Concrete blocks (8) are stacked and placed in parallel,
Add weight in the same way.

Since this concrete block retaining wall has a wider depth at the bottom, it is a method of forming a concrete block retaining wall using a weight-adding method that can withstand strong earth pressure.

〔Example〕

In the first invention, although Fig. 1.2 shows concrete being poured into each of the front spaces 5 and the rear spaces 6 to add weight, Fig. 3.4 shows the case where masonry is placed in the rear spaces 6. ing.

In the first invention as well, a side wall 10 having a concrete pouring window of 10° may be provided as shown in FIG. 2, or it may be formed in a U-shaped groove shape without a side wall as shown in FIG.

The base plate 1 is provided with uneven engaging step portions 16 and 17 (the reference numerals are the same as those in the second invention) that engage with the lower front W2 and the top of the middle wall 3.

The concrete block f at the top has no inner wall 3, and there are inner walls 1!3 from a to e.

Further, in the second invention, the rear closing plate 14 is attached to the fastening bolt 1.
8, and a concrete pouring window 15 for connecting concrete is formed in the side wall 13.

Engagement steps 16.1 with uneven surfaces are used to fix the front wall 12 that overlaps vertically.
7 will be provided.

Although the drawing shows a case of three stages, there are four stages.

It may be formed in multiple stages, such as five stages.

In the case of the side wall 10 and the side wall 13, concrete pouring windows 10° and 15 are not provided on the outer side wall of the product located at the end.

It is preferable to connect adjacent side walls using a bolt/nut method.

〔Effect of the invention〕

In both the first invention and the second invention, the concrete block bodies are mass-produced by mold production in a factory, transported to the site and placed side by side,
A completed concrete block body is made by pouring concrete.In the first invention, the space is square, so it is possible to remove the mold upward, and in the second invention, a cylindrical body without a bed plate is created using the same construction method. Therefore, it is possible to pull out the mold downward, and mold production is easy in both cases.

Concrete is then added to the wall by pouring it on-site to add weight to the wall, resulting in a larger, more stable retaining wall that is deeper toward the bottom, making this method of forming a concrete block retaining wall using a weight-adding method that can withstand strong earth pressure.

In particular, the concrete block retaining wall of the first invention has a step-like earth pressure receiving part at the rear, so it can withstand even stronger earth pressure.It has excellent practicality and can withstand super-load earth pressure. This is how the walls are formed.
