刘店矿井冻结法凿井关键技术浅析

针对深厚表土层冻结法凿井井壁安全,从冻结压力、提高井壁强度,尤其是高强度高性能混凝土配制等几个方面进行分析研究,对于以后类似地层条件下冻结法凿井井壁设计和施工安全有一定的借鉴和参考作用。

In view of the deep surface soil level freezing process drilling a well wall security, this article from the freeze pressure, enhances the wall intensity, particularly the high strength high performance concretes configuration and so on several aspects conduct the analytical study, the freezing process drilling a well wall design and the construction has certain model safely regarding the later similar formation condition under with the reference function.
