超长距离浅覆土大断面矩形顶管设计探讨

摘要:

随着城市化进程的迅猛发展,城市空间变得越来越拥挤,地下工程建设采用对周边环境影响小的非开挖技术是一种发展趋势和潮流。文章通过对某管廊矩形顶管工程的实例分析,介绍了富水砂性土层中超长距离浅覆土大断面矩形顶管的设计重难点和解决方案,同时也提出了作者的相关见解,对以后类似工程具有参考意义。

Abstract:

With the rapid development of urbanization, urban space becomes more and more crowded. It is a development trend and trend to adopt Trenchless Technology in underground engineering construction, which has little impact on the surrounding environment. Through the example analysis of a pipe gallery rectangular pipe jacking project, this paper introduces the design key and difficult points and solutions of super long-distance shallow soil covered large section rectangular pipe jacking in water rich sandy soil layer, and also puts forward the author"s relevant opinions, which has reference significance for similar projects in the future.
