SLOPE STABILIZATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a slope stabilization structure that suppresses seepage of an injection material into a highly permeable layer when such a layer is present in a natural ground, may be implemented readily, and minimizes decline in suppression force.SOLUTION: A reinforcing material 1, such as a rock bolt, is inserted in a drilled hole 3, along with an injection material 4. A seepage suppression tool is fitted at a location of the reinforcing material 1 that corresponds to a second layer 11, the seepage suppression tool suppressing seepage of the injection material 4 into the second layer 11. The seepage suppression tool has an opening at least on a top edge, and includes a shielding tube 20 that covers only a part of an entire length of a wall surface of the drilled hole 3 that faces the second layer 11, and a fixture 21 for fitting the seepage suppression tool to the reinforcing material 1.SELECTED DRAWING: Figure 1
【課題】地山に高透水層が存在している場合において、その高透水層への注入材の漏出を抑制でき、しかも、施工が容易であって、抑止力の低下を最小限に抑えることができる斜面安定化構造を提供する。【解決手段】削孔３内にロックボルト等の補強材１が挿入されると共に注入材４が注入され、第二層１１に対応した補強材１の位置に、注入材４が第二層１１に漏出することを抑制するための漏出抑制具が装着され、該漏出抑制具は、少なくとも上端が開口し、削孔３の壁面の全長のうち第二層１１に面する部分のみをカバーする遮蔽筒体２０と、補強材１に取り付けるための取付具２１とを備えている。【選択図】図１
