盾构全断面穿越玻璃纤维筋地下连续墙的施工技术

Construction Technology of Tunnel Shield for Full Cross-Section Passing Through Glass Fiber Reinforced Underground Diaphragm Wall

以实际工程为例,阐述了盾构全断面穿越玻璃纤维筋地下连续墙时的施工技术。通过工程风险分析,针对性地选择复合式土压平衡盾构机,并对进出地下连续墙两侧土体进行预加固,同时在掘进过程中严格控制施工参数,最终成功地穿越地下连续墙,且控制了已有结构的沉降量。

Taking practical engineering as an example, the construction technology of tunnel shield for full cross-section passing through glass fiber reinforced underground diaphragm wall has been expounded in this paper. Through the engineering risk analysis, targeted selection of composite earth pressure balance shield machine, pre-reinforcement of soil mass in and out on both sides of underground diaphragm wall, while at the same time, the construction parameter has been strictly controlled in the tunneling process and finally a successful passing through the underground diaphragm wall has been obtained and the settlement volume of the existing structure has been controlled accordingly.
