SEMI-ASSEMBLED ECOTYPE DEBRIS DAM FOR MUDFLOW AND CONSTRUCTION METHOD THEREOF

摘要

A semi-assembled ecotype debris dam for mudflow comprises a dam body foundation (2) and a dam body thereon. The dam body comprises a mudflow overflowing segment (3) and dam abutments being on the two sides of the overflowing segment (3). The mudflow overflowing segment (3) is constructed by mortar and masonry or concrete or reinforced concrete. The dam abutments are formed by several prefabricated reinforced concrete cuboid cases (1) being cross connected. The cuboid cases (1) are open in the top surface and are sealed in the other five surfaces. The interior of the cuboid cases (1) is filled with soil body and the surface of the soil body which is not covered by the upper cuboid cases (1) is planted with bushes or grasses. The gradients of the inside and outside slopes of the dam abutments are equal and the inside of the dam abutments is installed with a buffering cushion (9). Disclosed is also a construction method of the semi-assembled ecotype debris dam for mudflow.
