摘要
通过对冻结法施工理论的梳理、冻胀成因及其防护措施的分析,依据红岭煤矿东风井冻结法施工、防冻胀保护的施工经验,总结了冻结施工中防冻胀保护的可行方法,以保证已砌井壁不受破坏。
The paper analyzes the freezing construction theory, frost-heaving causes and protective measures, absorbs the construction experience of freezing construction and frost-heaving protection used in Dongfeng well of Hongling coal and mine, and summarizes the feasible frost-heaving protection methods in freezing construction, to ensure to prevent the finished shaft lining from being damaged.
