Abstract

PURPOSE:To disperse a horizontal pressure and form a firm retaining wall by piling tapered blocks having the sections gradually reduced on the inclined surface being mutually engaged, disposing reinforcements in through holes, and pouring concrete thereto. CONSTITUTION:Using tapered blocks 1 having the sections partly gradually reduced, first reinforcements 8a provided on a foundation 7 are inserted to the through hole 2 and left and right second recessed parts 5 of each block 1, respectively, to form the first stage of a retaining wall. Second directional reinforcements 9 are disposed over the first recessed parts 4 of the blocks. In the second step of the retaining wall, respective protruding parts 3 of adjacent second stage blocks are inserted to the third recessed parts 6 of the first stage blocks, whereby the blocks 1 are piled in the state where the reinforcements 8a and the like are inserted to the lateral second recessed parts 5 and through hole 2. After the blocks 1 are piled up, concrete 10 is poured into the parts into which the reinforcements are inserted to complete the retaining wall. The projecting part and recessed part of respective blocks are engaged to each other in the form where the upper stage block straddles the adjacent lower blocks, and reinforcements are vertically and horizontally passed through. Hence, a firm retaining wall difficult to have the influence of vibration can be formed.

Claims (5)

[Claims] (1) A through hole for inserting reinforcing bars in a first direction is formed between the opposing surfaces, and a groove-like hole is formed in at least one of the opposing surfaces for inserting reinforcing bars in a second direction. A first recess is formed to include the opening of the through hole, and the first recess is continuous with the first recess on at least one of the opposing surfaces and is perpendicular to the opposing surface. A second groove-shaped recess is formed for inserting reinforcing bars in one direction, and a third recess is formed on one of the opposing surfaces, and the second recess is inserted into the third recess when assembled. A block characterized in that a plurality of convex portions are formed on the other surface of the opposing surfaces. (2) The block according to claim 1, wherein the first recess is formed with a curved surface. (3) The block according to claim 1 or 2, wherein the second recesses are formed on both of the opposing surfaces. (4) Claim 1 in which reinforcing steel bars are arranged inside the structure.
, 2 or 3. (5) A first stage is formed in which reinforcing bars in the first direction are placed in at least one of the through hole and the second recess, and from the second stage onwards, the reinforcing bars in the first direction are placed in the third recess of each of the adjacent lower blocks. The convex portion of the block is inserted so that the upper block straddles both of the lower blocks, and the first
It is formed by repeating the work of inserting reinforcing bars in the direction of , and in the same stage, placing reinforcing bars in the second direction in the continuous first recess, and then concrete is placed in the space where the reinforcing bars are placed. A method for forming retaining walls, earth retaining walls, and fences using the block according to claim 1, characterized in that the block is injected.
