COMBINATION STRUCTURE OF LIGHTWEIGHT BANKING STRUCTURE BY FOAMING SYNTHETIC RESIN AND SLOPE FACE STRUCTURE BY SEDIMENT AND ITS CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To minimize the sliding movement and differential settlement of a sediment layer of a slope face structure in peeling, separation, an earthquake and traffic vibration from lightweight banking of the slope face structure, in a combination structure of a lightweight banking structure by a foaming synthetic resin and the slope face structure by sediment, and its construction method.;SOLUTION: This combination structure of the lightweight banking composed of a synthetic resin arranged between the ground and the back face ground continuing with the ground, and the slope face structure formed by filling and rolling the sediment between an earth retaining surface of a wall surface material fixed on the ground, the ground and the lightweight banking, and its construction method, are characterized in that the lightweight banking is formed by delivering/foaming and hardening a foaming synthetic resin raw material, and an inclination of a contact plane of the lightweight banking and the slope face structure is set to 45° or less.;COPYRIGHT: (C)2005,JPO&NCIPI
