JOINT FOR FREEZING PIPE, AND FREEZING PIPE
To improve workability of installing frozen pipes while ensuring liquid-tightness regardless of skill of a worker.SOLUTION: In a joint 4 for a freezing pipe, ends of a plurality of freezing pipe bodies 3 are connected to each other with threaded portions 44 to form a freezing pipe 2 that is inserted into a casing tube 1. An outer diameter of the largest outer diameter portion of the joint 4 for a freezing pipe is formed to be equal to or smaller than an outer diameter of the freezing pipe body 3.SELECTED DRAWING: Figure 2
【課題】作業員の技りょうによらず液密性を確保しつつ、凍結管の施工性を向上させること。【解決手段】凍結管用継手４は、ケーシングチューブ１内に挿入される凍結管２を構成するために、複数の凍結管本体３の端部同士を、ねじ部４４によって接続する凍結管用継手４である。凍結管用継手４の最も外径が大きい部分の外径が、凍結管本体３の外径以下となるように形成されている。【選択図】図２
