摘要
根据工程地质构造及水文地质条件,介绍了核桃峪风井冻结的技术参数,并对其施工中存在的技术难点进行了分析,总结了冻结实施情况,实践证明:采用该技术施工,上部已成井壁保护完好,创造了同类冻结工程在国内的最深历史记录。
According to the engineering geology structure and hydrology conditions,the paper introduces the freezing technology parameter of Hetaoyu air shaft,analyzes the construction technology difficulties,and summarizes freezing implementation conditions.Practice proves that applying the freezing construction technology not only protects the upper shaft wall well but also creates historical record in domestic similar freezing engineering.
