STRUCTURE AND METHOD FOR SUPPRESSING SEDIMENT COLLAPSE
PROBLEM TO BE SOLVED: To provide a structure and a method for suppressing a sediment collapse, capable of effectively suppressing a sediment collapse on a slope surface.SOLUTION: A sediment collapse suppression structure comprises a plurality of suppressing bodies 10 arranged on a slope surface, with an outer frame of the suppressing body connected mutually by a belt-form connecting material 20. The suppressing body includes: an anchor material installed by drilling the slope surface; a bearing plate installed on the slope surface by having a head part of the anchor material penetrated through a bolt hole; and a nut screwed on the head part of the anchor material. The bearing plate may apply pressure on the slope surface, by tightening the nut on the head part of the anchor material. The sediment collapse suppressing method includes the following steps for: drilling an anchor hole on the slope surface and installing the anchor material in the anchor hole; installing the bearing plate on the slope surface, by having the head part of the anchor material, which is exposed on the slope surface, penetrated through the bolt hole of the bearing plate; tightening an anchor bolt by screwing the nut on the head part of the anchor material, so that pressure is applied on the slope surface by the bearing plate; and mutually connecting an outer frame of the plurality of bearing plates arranged on the slope surface, with a belt-form connection material.SELECTED DRAWING: Figure 1
【課題】斜面の土砂崩壊を効果的に抑止することができる土砂崩壊抑止構造と土砂崩壊抑止工法を提供する。【解決手段】土砂崩壊抑止構造は、斜面に配置した複数の抑止体１０の外枠を帯状の連結材２０で相互に連結してなり、抑止体は、斜面を削孔して設置したアンカー材と、アンカー材の頭部をボルト孔に貫通させて斜面に設置した支圧板と、アンカー材の頭部に螺着したナットと、からなり、ナットをアンカー材の頭部に締結することで支圧板を斜面に加圧可能に構成した。土砂崩壊抑止工法は、斜面にアンカー孔を削孔し、アンカー孔内にアンカー材を設置する工程と、斜面から露出したアンカー材の頭部を支圧板のボルト孔に貫通させて、支圧板を斜面に設置する工程と、アンカー材の頭部にナットを螺着してアンカーボルトを緊張することで、支圧板を斜面に加圧する工程と、斜面に配置した複数の支圧板の外枠を帯状の連結材で相互に連結する工程と、を含む。【選択図】図１
