CONNECTION STRUCTURE BETWEEN SUBMERGED CAISSON BODIES, CONSTRUCTION METHOD OF SUBMARINE TUNNEL AND SUBMERGED CAISSON BODY
PROBLEM TO BE SOLVED: To provide a connection structure between the submerged caisson bodies capable of connecting the submerged caisson bodies to each other with a simple structure for a submerged tunnel which can follow a deformation as a whole.SOLUTION: A seal member 39 is disposed between end members 31. The seal member 39 is then sandwiched between submerged caisson bodies 7 and connected to each other while pressing one submerged caisson body 7 to the other submerged caisson body 7. Steel bars 35a are then connected to couplers 35. A concrete sleeve 41 is formed by casting concrete embedding steel bars 33a. More specifically, the concrete sleeve 41 is provided at an inner periphery side of the end members 31 crossing the end members 31 and is integrated with the end members. A caisson body connection segment 47 is constituted of a pair of the end members 31 and the concrete sleeve 41 connecting them. More specifically, the caisson body connection segment 47 is disposed between the submerged caisson bodies 7, and the submerged caisson bodies 7 are connected to each other by means of the caisson body connection segment.SELECTED DRAWING: Figure 8
【課題】沈埋トンネル全体として変形に追従可能であり、簡易な構造で沈埋函体同士を接続することが可能な沈埋函体同士の接続構造等を提供する。【解決手段】それぞれの端部部材３１同士の間に、シール部材３９を配置する。次に、一方の沈埋函体７を他方の沈埋函体７に押し付けて、沈埋函体７同士でシール部材３９を挟み込んで接続する。次に、カプラー３５には鉄筋３５ａが接続される。鉄筋３３ａが埋設するように、コンクリートを打設して、コンクリートスリーブ４１を形成する。すなわち、コンクリートスリーブ４１は、端部部材３１同士にまたがるように端部部材３１の内周側に設けられ、端部部材と一体となる。なお、一対の端部部材３１およびこれを接続するコンクリートスリーブ４１を合わせて、函体接続セグメント４７とする。すなわち、沈埋函体７の間に函体接続セグメント４７が配置され、沈埋函体７同士が函体接続セグメントで接続される。【選択図】図８
