摘要
地质条件复杂的长距离联络通道施工风险高、难度大,冻结法施工也存在较多风险因素。介绍某地铁长距离联络通道兼泵房工程冻结设计及造孔施工、积极冻结以及开挖构筑施工等情况,分析了冻结法施工技术存在的问题,并提出了对策。该工程冻结及开挖构筑施工取得预期效果。
A long distance cross passage with a complicated geological condition would have a high construction risk and a high difficulty and the ground freezing method construction also would have many risk factors The paper introduced the ground freezing design,borehole drilling construction,active freezing and structure excavation construction and other condition of the long distance cross passage and simultaneously as the pumping room in a metro system The paper analyzed the problems existed in the construction technology of the ground freezing method and provided the relevant countermeasures The expected effect of the ground freezing and structure excavation construction were obtained.
