Construction method suitable for oversized circular subway station
The invention provides a construction method suitable for an oversized circular subway station. The construction method includes the following steps that S1, pipelines are moved and changed, and a site is leveled; S2, cement mixing pile constructionis conducted; S3, guide wall construction is conducted: after a groove wall is reinforced and reaches the design strength, guide wall construction is conducted; S4, underground diaphragm wall construction is conducted; S5, top beam and reinforced concrete support construction is conducted; S6, foundation pit excavation and steel support construction are conducted; S7, main body structure construction is conducted: a main body structure of the station is a cast-in-place reinforced concrete frame structure, an open excavation sequential construction method is adopted for construction, and the construction principle of longitudinal segmentation, horizontal layering and from bottom to top is followed during construction. According to the construction method suitable for the oversized circular subway station, the unsupported exposure time and space of a foundation pit are reduced, and the construction safety is improved; the construction difficulty of a circular underground diaphragm wall and a circular main body structure is reduced; the construction difficulty of the connection section of a circular part and a straight-line station body is reduced; shield receiving and shield launching are reasonably considered; and the construction efficiency is improved, and the construction period is shortened.
本发明提供了一种适用于超大圆形地铁车站的施工方法，包括以下步骤：S1、管线迁改及场地整平；S2、水泥搅拌桩施工；S3、导墙施工；当槽壁加固完成达到设计强度后进行导墙施工；S4、地下连续墙施工；S5、冠梁、钢筋混凝土支撑施工；S6、基坑开挖及钢支撑施工；S7、主体结构施工；车站主体结构为现浇钢筋混凝土框架结构，采用明挖顺作法施工，施工时遵循″纵向分段，水平分层，从下至上″的施工原则。本发明减少了基坑无支撑暴露时间和空间，提高施工的安全性；本发明降低了圆形地下连续墙、圆形主体结构的施工难度；本发明降低了圆形部分与直线段站体连接段施工难度；本发明合理考虑盾构接收和盾构始发；本发明提高了施工效率，缩短了施工工期。
