METHOD FOR INSTALLING SCOURING PREVENTION MAT, METHOD FOR CONSTRUCTING SCOURING PREVENTION STRUCTURE, AND SCOURING PREVENTION MAT
To provide a method for installing a scouring prevention mat, a method for constructing a scouring prevention structure, and a scouring prevention mat which suspend a scouring prevention mat in a stable attitude while preventing damage ti the scouring prevention mat and can install the scouring prevention mat at a water bottom.SOLUTION: A scouring prevention mat 1 includes a mat body 2 where a hole 3 is formed at its center, and a plurality of suspension parts 6 and 7 which are exposed at prescribed intervals in a circumferential direction in each of an outer edge 4 side and an inner edge 5 side of the mat body 2. In order to construct a scouring prevention structure 36, a scouring prevention mat 1 is suspended and installed at a water bottom using a suspension balance 13 composed of an outer frame 14 suspending the suspension part 6 on the outer edge 4 side of the mat body 2 and an inner frame 15 suspending the suspension part 7 on the inner edge 5 side. Then, a pile-like underwater structure is placed so as to penetrate the hole 3 of the scouring prevention mat 1, and a filter unit 33 where a net body is filled with stone or crushed stone is installed above a clearance between the inner edge 5 of the mat body 2 and the underwater structure.SELECTED DRAWING: Figure 1
【課題】洗掘防止マットを損傷を防止しつつ安定した姿勢で吊り下げて水底に設置できる洗掘防止マットの設置方法、洗掘防止工の施工方法および洗掘防止マットを提供する。【解決手段】洗掘防止マット１は、中央に孔３が形成されたマット本体２と、マット本体２の外縁４側と内縁５側のそれぞれにおいて周方向に所定の間隔で露出する複数の吊り部６、７とを具備する。洗掘防止工３６を施工するには、まず、マット本体２の外縁４側の吊り部６を吊り下げる外枠１４と内縁５側の吊り部７を吊り下げる内枠１５とからなる吊り天秤１３を用いて、洗掘防止マット１を水底に吊り下ろして設置する。その後、洗掘防止マット１の孔３を貫通するように、杭状の水中構造体を打設し、マット本体２の内縁５と水中構造体との隙間の上方に、網体に石又は砕石が充填されたフィルターユニット３３を設置する。【選択図】図１
