Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete block assembly retaining wall constructed for slope protection.

Conventionally, there are various types of blocks of this type, but since the blocks are stacked one by one for construction, it requires a considerable amount of manpower.

In addition, there are many cases where the buried chestnut stones move and bulge out at the center of the slope, which weakens the wall and causes it to lose stability, resulting in individual blocks falling off and falling over. Ta.

This invention was developed in view of the above circumstances.

The following description will be made based on the illustrated embodiments. The retaining wall of this invention consists of stacking blocks 1 shown in FIGS. 2 to 4,
Blocks 2 shown in FIGS. 5 to 8 are shown in the upper and lower rows.
It will be arranged.

Block 1 consists of three rectangular plates with a long side to short side ratio of 2:1, which are integrated horizontally so that the long sides overlap each other by half. A front plate 3 and a rear plate 4 having approximately the same shape with serrated side edges formed.
are provided in parallel and facing each other, and the front and rear plates are connected by connecting pieces 5 at three locations vertically downward from the apex of the upper side side to the lower side side, and a space 6 is formed between the connecting pieces 5, 5. It has a shape of three single rectangular blocks.

On the other hand, block 2 has two sides that will be the top in a chevron shape and two sides that will be the top.
A scalene pentagonal front plate γ with parallel sides and a rear plate 8 are provided parallel to each other at a required interval and facing each other, and connecting pieces 9,9
The connecting pieces 9 are integrally connected with each other, and a space 10 is provided between the connecting pieces 9. When the connecting pieces 9 are disposed laterally, the top portion becomes serrated.

Using the above blocks 1 and 2, in the case of volume, first level the construction ground and lay down the foundation piles etc. as appropriate.

On top of that, blocks 2 are laid horizontally in parallel at a predetermined slope, and the blocks 1 are piled up so that the serrations on the sides fill the valleys of the blocks 2, and the blocks 1 are placed on top of each other in the serrations. They are interlocked and stacked one after another to a predetermined height, and the uppermost block is interlocked so as to fill the gap between the serrations of the block 1, and the blocks 2 are arranged horizontally in parallel and constructed.

And backfilling is done in each space 6.1 of blocks 1 and 2.
0. In addition, the entire retaining wall is fixed by any method of construction such as adding chestnut stone or concrete as appropriate.

The present invention has the above-mentioned configuration, and has front and rear plates each having a shape in which a required number of oblique rectangles are connected to each other, and the sides are serrated. It is constructed by stacking several rectangular blocks that are integrally formed, so three conventional single rectangular blocks can be constructed at the same time.
It has the characteristics that it can be built in a short period of time, saving a lot of time and effort as it is piled up individually.

Furthermore, by filling the space between the front and rear panels with mortar, stone, concrete, etc., the blocks are completely connected and integrated, and the three rectangular blocks are integrated into 18 blocks. It has a structure that is more stable in terms of strength than one in which pieces are piled up.

Claims (1)

[Claims] 1 Three rectangular plates each having a length of 2:l with a long side to short side ratio are formed into a continuous horizontally integral shape such that the long sides overlap each other by half, and the upper and lower sides are A front plate and a rear plate of approximately the same shape formed in a sawtooth shape are provided in parallel and oppositely, and between the front and rear plates there are connecting pieces at three points extending vertically downward from the apex of the upper side to the lower side. A block 1 is formed by connecting a block 1 with a space between the connecting pieces, and a front plate and a rear plate, each of which has two top sides formed in a chevron shape and two opposite sides parallel to each other, and is connected by a connecting piece. Blocks 2 are arranged horizontally in the upper and lower tiers so that the tops are serrated upward or downward, and in the middle tier, blocks 1 are stacked so that the serrated parts of their sides engage with each other.
