摘要
地铁车站基坑开挖会对临近已有的地下管线造成一定的影响。本文总结分析了地下管线的一般失效模式。在总结已有地下管线的使用情况及保护措施的基础上,针对具体工程提出了自来水管悬吊保护处理措施的建议,叙述了管线悬吊保护的方法和步骤、进行了悬吊纵梁的强度及变形验算,证明了该方法的合理性。最后提出了管线悬吊保护中的注意事项。
Abstract
The underground pipeline near subway foundation pit will be affected by the excavation, in this paper the authors analyzed the general failure mode of the underground pipeline. After investigated the usage of underground pipeline and protection measures, the paper put forward a overhanging method aim at protecting water pipe. Then Combined with practical engineering, the overhanging protection method is introduced detailedly, and the strength and deformation of girder are checked also. In the last of the paper, some matters of attention in the pipeline suspension protection are put forward.
