Gravitational force type retaining wall and its production manner

摘要

PURPOSE: To improve workability, and to enhance the whole rigidity by engaging each lower edge with projections on a sleeper material and placing concrete between a front wall and a rear wall held and juxtaposed by a strut member and a tension member. ;CONSTITUTION: Sleeper materials 1 having positioning projections 2-5 at the front ends and rear ends of top faces are arranged in parallel on the same surface in a flat surface, on which stone 6 is paced and tamped. A rear wall 10 composed of a concrete board, in which reinforcements are incorporated, is hung down, the lower edge of the rear wall is engaged with the front surfaces of the rear-end projections 4, 5 of the sleeper materials 1, and strut members 14 are disposed among the rear wall 10 and the sleeper materials 1 and the rear wall 10 is held at a forward inclined attitude. A front wall 9, in which reinforcements are incorporated, is hung down, the lower edge of the front wall is engaged with the rear surfaces of the front-end projections 2, 3 of the sleeper materials 1, and tension members 21 are arranged between the front wall 9 and the sleeper members 1 and the front wall 9 is held at an approximately vertical attitude. Another front wall and rear wall are installed to other sleeper materials, and concrete is placed in spaces 34 between each front and rear wall 9, 10.;COPYRIGHT: (C)1993,JPO&Japio
