城市地铁站点盾构穿行处玻璃纤维筋地下连续墙施工技术

Construction Technology of Glass Fiber Reinforced Diaphragm Wall at Shield Passing Through Urban Subway Station

为避免盾构机始发时,一般地下连续墙需要进行烦琐的预处理过程,且存在较高危险性的问题,采用具有抗拉性能高、抗剪性能较差特点的玻璃纤维筋取代普通钢筋来施工地下连续墙。在满足对地铁车站主体结构的围护作用要求的前提下,为盾构机施工预留了前进通道,避免了盾构施工时对地下连续墙等支护结构的预处理作业。

In order to avoid the tedious pretreatment process of diaphragm wall when the shield machine starts,in addition,there are high risk problems.The glass fiber rebar with high tensile property and poor shear property is used to replace the ordinary rebar in the construction of diaphragm wall.On the premise of meeting the enclosure requirements of the main structure of subway station,the forward passage is reserved for the shield machine construction,which avoids the pretreatment of the diaphragm wall and other supporting structures during the shield construction.
