Discussion and Analysis on Main Problems of Rectangular Pipe Jacking Method in Shallow Underground Space Construction and Control Measures

随着地下空间的开发利用,矩形顶管工法在地下工程施工中应用逐渐广泛,针对矩形顶管法在浅层地下空间施工中存在的主要问题及控制措施,依托深圳市轨道交通8号线深外高中站B2出入口矩形顶管工程,结合其他工程对施工中存在的风险、主要的问题进行分析,对控制、解决措施进行探讨研究,并提出几点建议为工程技术人员今后类似工程设计、施工提供参考借鉴。

With the development and utilization of underground space, the rectangular pipe jacking method has been widely used in the underground engineering construction. The main problems of the rectangular pipe jacking method existing in the shallow underground space construction and the control measures are analyzed. Relying on the rectangular pipe jacking project at B2 Entrance and Exit of Shenwai High School Station of Shenzhen Metro Line 8, the risk and the main problems exiting in the construction are analyzed in combination with the other projects. The control and solving measures are discussed and studied. And some suggestions are proposed to provide the reference for the design and construction of the similar projects in the future.
