Discussion on the attentive problems of sinking using freezing method

介绍了冻结法凿井的原理,从掘进段高的确定、冻结管的断裂问题、冻结井壁的破裂方面探讨了冻结凿井施工中的问题,并针对性的提出了相应的解决办法,对冻结法凿井施工具有一定的指导意义。

The principle of sinking using freezing method was introduced, the questions existing in freezing sinking construction were discussed from height of excavation section determination, rupture question of freezing pipe and fracture question of freezing shaft lining, so as to provide references for sinking construction using freezing method.
