在地铁工程施工过程中,盾构接收是一个施工风险高、施工难度大的环节。在施工过程中,由于环境复杂,盾构在接收的过程中容易出现涌砂、漏水等风险,为了保证盾构可以安全出洞,需要选择合理的盾构接收方案。本位以实际工程为例,首先对盾构钢套筒接收过程中反力架受力安全性进行了分析,然后从钢套筒进场、钢套筒组装、反力架和支撑安装等几个方面对地铁工程中盾构钢套筒接收施工技术进行了探讨。
In the subway construction process, the shield is a high risk of construction, construction of a large part of the difficulty. In the process of construction, due to the complex environment, the shield is prone to the risk of sand gushing and water leakage during the receiving process. In order to ensure that the shield can safely exit the tunnel, a reasonable shield receiving scheme needs to be selected. Based on the actual project, this paper firstly analyzes the force safety of the reaction force frame during the receiving process of the shield steel sleeve, and then from the steel sleeve approach, the steel sleeve assembly, the reaction frame and the support installation several In the meantime, the construction technology of shield steel sleeve receiving in subway project is discussed.
