关于矩形顶管法施工地铁出入口始发、接收方式的研究及案例分析

Study and Analysis on Starting and Receiving Modes of Rectangular Pipe Jacking in Construction of Metro Entrance and Exit

摘要:

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的应用逐渐广泛，出现了多种不同类型的矩形顶管施工案例，特别在地铁出入口施工中。通过对国内既有施工案例的介绍，研究分析了地铁出入口采用矩形顶管法施工时始发、接收方式的特点，结合施工工况等影响因素，总结了目前矩形顶管法施工地铁出入口始发、接收方式及设计原则。在地下过街通道、地铁出入口、商场出入口等设计施工时，该始发、接收方式的设计原则、施工技术可为工程技术人员今后类似工程设计、施工提供参考依据。

Abstract:

With the development and utilization of underground space, the rectangular pipe jacking method has been widely used in underground engineering construction. There are many different types of rectangular pipe jacking constructions, especially in the construction of metro entrance and exit. By introducing the existing construction examples in China, the characteristics of starting and receiving modes in the rectangular pipe jacking construction adopted for the metro entrance and exit are studied and analyzed. Combined with the influential factors of construction conditions, the starting mode, receiving mode and design principles of rectangular pipe jacking in the construction of metro entrance and exit are summarized. When the design and construction of underground street passage, metro entrance and exit, and market entrance and exit, the design principles and construction technologies of the starting and receiving modes can be referred for the engineering technicians to design and construct the similar projects in the future.
