TREMIE PIPE
PROBLEM TO BE SOLVED: To provide means for smoothly inserting or extracting a tremie pipe to the inside of a reinforcement cage.SOLUTION: A tremie pipe 4 comprises an opening part 42 of becoming a discharge port of concrete on a side surface in the vicinity of a tip part of a body 41. The tremie pipe 4 also comprises a tapering-off conical guide member 43 continuously provided in the tip part of the body 41. The length of a bus bar of the guide member 43 is longer than an interval of an annular reinforcement of a reinforcement cage 2 for receiving insertion of the tremie pipe 4. When the tremie pipe 4 is inserted into the inside of the reinforcement cage 2, a side surface of the guide member 43 moves while contacting with any annular reinforcement. A corner part of the tip part is guided in the inside direction of the annular reinforcement by the guide member 43 when approaching the any annular reinforcement. As a result of it, the corner part of the tip part is not hitched on the annular reinforcement.SELECTED DRAWING: Figure 2
【課題】鉄筋かごの内部に対するトレミー管の挿入または引き抜きがスムーズに行われるための手段を提供する。【解決手段】トレミー管４は本体４１の先端部付近の側面にコンクリートの排出口となる開口部４２を有している。また、トレミー管４は本体４１の先端部に連続して設けられた先細りの円錘状の誘導部材４３を有している。誘導部材４３の母線の長さは、トレミー管４の挿入を受け入れる鉄筋かご２の環状筋の間隔より長い。トレミー管４が鉄筋かご２の内部に挿入される際、誘導部材４３の側面がいずれかの環状筋に接しながら移動する。先端部の角部はいずれかの環状筋に近付く際、誘導部材４３により環状筋の内側方向に導かれる。その結果、先端部の角部が環状筋に引っ掛かることがない。【選択図】図２
