CONSTRUCTION OF RETAINING WALL OF LLSHAPED CONCRETE BLOCK INTEGRALLY COMBINED TO GROUND

摘要

PURPOSE:To construct a retaining wall capable of sufficiently withstanding earthquake, flood, etc., by burying the stay and fixing parts of L-shaped concrete blocks deep into the ground so as to integrally combine them. CONSTITUTION:A stay 3 extending at right-angle from a wall-forming part 2 is provided at a place corresponding to almost 1/4 of the wall width on the back of the wall-forming part 2, a fixing part 4 having a vertical through hole 6 for iron bar is provided at the tip of the stay 3 and a vertical through hole 5 for iron bar is also provided in a given part of L-shaped concrete block 1. After consolidating a given part of the ground, base concrete is horizontally placed, the vertical iron bar is buried and fixed in a given position, and then the iron bar is fitted into the iron bar holes 5 and 6 of the block 1 and combined them in either normal state or reverse state by a push claw 10 and a receive claw 11 to construct the first step. Then, bedding soil is filled in a necessary position and the second step is constructed in reverse state to the first step. Afterwards, the operation is repeated to construct the retaining wall to a given height. Thus, the stay 3 and fixing part 4 can be integrally combined to the ground by forming a fixed column.
