ASEISMIC JOINT, AND CONSTRUCTION METHOD FOR ASEISMIC PIPE PORT STRUCTURE
PROBLEM TO BE SOLVED: To provide an aseismic joint of a simple structure that may be installed readily, allowing flexible connection between a rehabilitation pipe and a connection hole formed in a side wall of a manhole, while maintaining water-tightness.SOLUTION: An aseismic joint includes outer and inner rubber joints 2, 3 disposed between a connection hole and a rehabilitation pipe, and first and second compression members 4, 5 for sandwiching the outer and inner rubber joints 2, 3 in an axial direction. First and second protrusions 4b, 5b are formed on the first and second compression members 4, 5, the protrusions being fitted between the outer and inner rubber joints 2, 3 and having an outer diameter tapered toward a tip side and an inner diameter expanding toward the tip side. The outer rubber joint 2 is widened and expanded in a radial direction by the first and second protrusions 4b, 5b, and thus pressed against and fixed on a hole wall of the connection hole. The inner rubber joint 3 is narrowed and expanded inwardly by the first and second protrusions 4b, 5b, and thus pressed against and fixed on an outer peripheral surface of the rehabilitation pipe.SELECTED DRAWING: Figure 3
【課題】簡単な構造で且つ施工が容易でありながら、水密性を維持しつつ人孔の側壁に形成された接続孔と更生管とを柔軟に接続する。【解決手段】接続孔と更生管との間に配置される外側および内側ゴムジョイント２，３と、外側および内側ゴムジョイント２，３を軸方向に挟む第１および第２圧縮部材４，５とを備えた耐震継手である。第１および第２圧縮部材４，５には、外側および内側ゴムジョイント２，３の間に嵌り、且つ、先端側へ行くほど、外径が小さくなる一方、内径が大きくなる第１および第２突条部４ｂ，５ｂが設けられている。外側ゴムジョイント２は、第１および第２突条部４ｂ，５ｂにより拡径され且つ径方向外側に膨張することで接続孔の孔壁に圧着固定され、内側ゴムジョイント３は、第１および第２突条部４ｂ，５ｂにより縮径され且つ径方向内側膨張することで更生管の外周面に圧着固定される。【選択図】図３
