探究地铁车站冷冻暗挖隧道防水施工技术
摘要
随着我国地铁事业的发展,地铁工程对隧道施工技术的要求越来越高。基于此,文章分析了冷冻法施工原理,从地质预报及资料核实、冷冻法施工要点、初期防护施工、开挖及支护与防水关系、规避混凝土衬砌裂缝等方面,探析了地铁车站冷冻暗挖隧道防水施工技术。权作引玉之论,为相关研究提供参考。
With the development of subway industry in our country, there ishigher and higher requirement for tunnel construction technology in subway engineering. Based on this, this paper analyzes the construction principle of freezing method, from the aspects of geological prediction and data verification, key points of freezing method construction, initial protection construction, relationship between excavation and support and waterproofing, avoidance of concrete lining cracks, etc. This paper probes into the waterproof construction technology of frozen undercut tunnel in subway station, in order to provides a reference for related research.
