Pipe type surface collapse prevention facility and construction method of pipe type surface collapse prevention facility

摘要

PROBLEM TO BE SOLVED: To provide pipe-type shallow landslide prevention facilities capable of inexpensively suppressing the rotation and displacement of a pile head.SOLUTION: In facilities for preventing a shallow landslide on a slope, pipe anchors A are installed by being juxtaposed at each predetermined interval in a lateral direction in an object range where a moving bed requiring shallow landslide countermeasures exists. The pipe anchors A are connected together by a rope body 102 to be capable of suppressing the rotation and displacement of a pile head.SELECTED DRAWING: Figure 1
