PIPE RETAINER

PROBLEM TO BE SOLVED: To provide a pipe retainer capable of preventing a displacement of pipe by a simple member even if a foundation shows embrittlement due to liquefaction phenomenon by earthquake.SOLUTION: There are provided a base block 1 installed at a reference plane in the underground area, a set of retainer members 2, 2 attached to the upper surface of the base block 1 and contacted with a peripheral surface of a pipe 3 and a retainer rope 4 fastening the peripheral surface of the pipe 3 with the base block 1 and fixing them. Soil and sand are buried back into a groove under a state in which the pipe 3 is fixed to a retainer 10, the soil and sand enter into a clearance between an upper surface 1a of the base block and the pipe 3, resulting in that the pipe 3 is rigidly fixed in the underground and the base block 1 becomes a resistance member against a force applied in a lifting direction.SELECTED DRAWING: Figure 4 【課題】 地震による液状化現象等によって地盤が脆弱になった場合でも配管のずれを簡易な部材によって防ぐことができる配管の固定装置を提供する。【解決手段】 地中の基準面に載置する基台１と、基台１の上面に取り付けられると共に配管３の周面に接触する一組の固定部材２、２と、配管３の周面と基台１とを締め付けて固定する固定ひも４とを備えており、配管３が固定装置１０に固定された状態で、溝に土砂を埋め戻すことによって、土砂は、基台の上面１ａと配管３との隙間に入り込むことから、配管３が地中で強固に固定されることとなり、基台１が浮き上がる方向の力に対して抵抗となる。【選択図】図４
