BANKING/ROCK MASS COMPOSITE REINFORCEMENT SOIL WALL STRUCTURE AND BANKING/ROCK MASS COMPOSITE REINFORCEMENT SOIL WALL CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reinforcement soil wall construction method in which a construction influence range is reduced and an excavation/banking soil quantity is suppressed to a minimum.;SOLUTION: A rock mass reinforcement soil wall part 4 is formed by fixing a front end portion of a rod-like reinforcement material 3 which is fixed while being driven to the side of a rock mass M through a plurality of lower layer precast plates 2, 2a... arrayed on a foundation 1 constructed on a slope S, to the lower layer precast plates 2, 2a..., a front end portion of a banking reinforcement material 6 is connected to back surfaces of a plurality of upper layer precast plates 5, 5a... arrayed on the top stage of the lower layer precast plates 2, 2a... in the rock mass reinforcement soil wall part 4, and a banking part 8 to embed the banking reinforcement material 6 therein is applied between the back surfaces of the upper layer precast plates 5, 5a... and the slope S to form a banking reinforcement soil wall part 9. Therefore, a construction influence range on the slope S is limited into a construction portion of the foundation 1 and a portion to which the banking reinforcement material 6 is abutted as needed, and can be limited to a narrow range.;COPYRIGHT: (C)2014,JPO&INPIT
