FREEZING PIPE AND FREEZING METHOD
To provide a freezing pipe and a freezing method which does not require welding between freezing pipes and which is applicable to limited freezing.SOLUTION: The present invention has a boring head (30) screwed to a tip, consists of a plurality of drilling rods (10) whose connection points have sealing performance, and has a seamless refrigerant supply pipe (6) inserted into the drilling rod (10). The drilling rod (10) functions as a freezing pipe outer pipe (10) after the refrigerant supply pipe (6) is inserted. A refrigerant header (20) which is detachable from the freezing pipe outer pipe (10) and is in communication with the region between the freezing pipe outer pipe (10) and the refrigerant supply pipe (6), and the constituent members of the freezing pipe can be connected or assembled by screwing, and can be disassembled into member units by screwing off.SELECTED DRAWING: Figure 4
【課題】凍結管同士を溶接する必要がなく、且つ、限定凍結にも適用可能な凍結管及び凍結工法の提供。【解決手段】先端に螺合接続されたボーリングヘッド（３０）を有し、接続箇所がシール性能を有する複数の削孔ロッド（１０）から構成され、削孔ロッド（１０）に挿入される継ぎ目の無い冷媒供給管（６）を有し、削孔ロッド（１０）は冷媒供給管（６）が挿入された後は凍結管外管（１０）として機能し、凍結管外管（１０）に対して着脱自在で且つ凍結管外管（１０）と冷媒供給管（６）の間の領域に連通している冷媒用ヘッダー（２０）と、凍結管の構成部材が、螺合により接続または組み立てられ、螺合解除によって部材単位に分解することができる。【選択図】図４
