Supporting truss capable of being recycled, foundation pit supporting system and subway station construction method
The application provides a supporting truss capable of being recycled, a foundation pit supporting system and a subway station construction method. The supporting truss is used in the foundation pit supporting system of a construction subway station and comprises two chord members and a web member, the two chord members are arranged at interval and in an up and down mode, and the two ends of eachchord member are detachably connected to an enclosure body of the foundation pit supporting system; and the web member is connected between the upper chord member and the lower chord member. Accordingto the supporting truss, the supporting truss is spliced by using the prefabricated chord members and the web member, so that the construction process of cast-in-place concrete forming of the supporting truss is omitted, after the supporting work is completed, direct detaching can be conducted, the construction difficulty of the supporting truss is reduced accordingly, and meanwhile, the construction period is also shortened.
本申请提供一种支撑桁架、基坑支护系统以及地铁车站的施工方法。支撑桁架用于施工地铁车站的基坑支护系统中，包括弦杆件和腹杆件。两弦杆件上下间隔设置，每一弦杆件的两端分别可拆卸地连接在基坑支护系统的围护体上。腹杆件连接在上部的弦杆件和下部的弦杆件之间。本申请提供的支撑桁架，通过使用预制的弦杆件和腹杆件拼接而成，从而免去了支撑桁架的现场浇筑混凝土成型的施工工序，且支护工作完成后，可以直接拆除，从而降低了支撑桁架的施工难度，同时也缩短了工期。
