The steel framework for sand arrestation soil saving it is to obtain the cushioning structural null sand arrestation

摘要

PROBLEM TO BE SOLVED: To provide a cushioning structure for preventing damaging of a steel frame dam by impact force of an avalanche of sand and stone, and its construction method, in the steel frame dam for erosion control and soil saving.;SOLUTION: Sill concrete is arranged on the ground of a position separated from a dam on the upstream side of the steel frame dam. An outer wall is arranged on the sill concrete so as to cover an upstream side wall surface of the dam for receiving impact by the avalanche of sand and stone and driftwood. A filler having cushioning performance is filled between the outer wall and the upstream side wall surface of the dam.;COPYRIGHT: (C)2008,JPO&INPIT
