摘要
针对井筒和装载溜槽室冻结施工的特点,计算了冻结壁厚度,选用主孔一次冻全深加防片帮孔及加强孔的冻结方案,对冻结过程进行监控。结果表明,自冻结站运转期间,冻结壁温度场能够迅速形成和发展,冻结壁顺利交圈。
Based on the features of shaft and loading belt cabinet, the thickness of frozen wall was calculated, the frozen plan of main hole once frozen with rib spallingproof hole and strengthening hole was settled, the frozen process was monitored. The result showed that frozen wall temperature field enables to form and develop vastly and hand in circle during frozen station operation.
