摘要： PURPOSE: To prevent the looseness or collapse of the ground and to minimize a construction space by driving a plurality of pile members in the ground at specific intervals, excavating the front side of a group of pile members, at the same time, excavating the ground betwee the pile members in the shape of a recess, and mounting recessed wall members corresponding to the recessed excavation section between the bile members. CONSTITUTION: A plurality of pile members 1 are antecedently driven in the ground at specific intervals. Then, the frontside of a group of pile members 1 is excavated up to specific depth and, at the same time, the ground between the pile members is excavated in the shape of a recess. Then, wall members 2 formed of recessed plate bodies corresponding to recessed excavation section are mounted between the pile members 1 through joint pieces 21. By the constitution, the looseness or collapse of the ground can be prevented, and a space for earth retaining construction is minimized to make it possible to promote economic efficiency.

摘要： PROBLEM TO BE SOLVED: To provide an impervious wall method excellent in the long term stability of impervious performance.
SOLUTION: A casing 3 is pierced to a predetermined position by pressing the casing and excavating the inside of the casing, a predetermined amount of bentonite mixed soil 1 is thrown in an excavated hole, the casing is pulled out up to a predetermined height, the bentonite mixed soil thrown is compacted, the throwing of the bentonite mixed soil, the pulling out of the casing and the compaction are repeated to construct a pile body 2 formed of the bentonite mixed soil with a predetermined length, and the construction of the pile body is repeated to form a method constructing a wall body 20 in the ground by continuing the pile body. In order to ensure a homogeneous physical property over the overall length of the pile body and integrity with the peripheral ground, the bentonite mixed soil is thrown by a proper amount so as to be sufficiently compacted to carry out compaction.

摘要： PROBLEM TO BE SOLVED: To efficiently and economically assemble a cylindrical reinforcement cage without taking a time for arranging cables. SOLUTION: A central guide 33, end guides 32 and a fixing tubular body are used for assembling a cylindrical reinforcement cage, and cables, which are horizontally drawn, are arranged in the semicircular condition along a guide plate 321 of the inner peripheral surface of each end guide 32, and the fixing tubular body is fitted from over the cables and the central guide 31, and the cables, which are horizontally drawn, are arranged in the semicircular condition along the guide plate of an upper half part of the fixing tubular body, and the tip of each cable is aligned at the end of the fixing tubular body. The end guides 32 are eliminated, and the tip of each cable is fixed to the fixing tubular body, and thereafter, the central guide 31 is eliminated, and the cables are thereby arranged in the cylindrical condition.
