Underground continuous wall construction method and structure convenient for subway shield passing through
The invention discloses an underground continuous wall construction method and structure convenient for subway shield passing through. According to the underground continuous wall construction methodand structure convenient for subway shield passing through, an underground continuous wall (1) is built by adopting a framing groove forming and cast-in-situ wall forming method to resist earth pressure, a water stop connection method is adopted between amplitude and amplitude to form a water stop curtain, the underground continuous wall (1) is internally provided with steel bars (2), fiber bars (4) are adopted to replace the steel bars (2) within a planned subway shield passing-through protection range (3), and the fiber bars (4) are connected with the steel bars (2) outside the planned subway shield passing-through protection range (3) to prevent damage to a shield cutter disc during subway construction. By means of the underground continuous wall construction method and structure convenient for subway shield passing through, the disadvantages of a traditional underground continuous wall being prone to causing damage to the shield cutter disc, difficult to pass through and the like are broken through, the deep foundation pit support protection force bearing and safety requirements can be met, shield smooth passing through can also be facilitated, the national underground space utilization and sustainable development policy is met, and the purpose of underground space comprehensive utilization is achieved.
本发明公开了一种便于地铁盾构穿越的地下连续墙施工方法及结构，本发明的地下连续墙（1）采用分幅成槽，现浇成墙的方法建造以抵抗土压力；幅与幅之间采取止水连接方式以形成止水帷幕；地下连续墙（1）内设有钢筋（2）；在规划地铁盾构穿越的保护范围（3）内采用纤维筋（4）代替钢筋（2），纤维筋（4）与规划地铁盾构穿越保护范围（3）外的钢筋（2）连接；以防止在地铁施工时对盾构刀盘造成破坏。本发明突破传统地下连续墙易造成盾构刀盘破坏、穿越困等弊端。既满足深基坑支护受力和安全要求；又能便于盾构顺利穿越。符合国家地下空间利用和可持续发展政策，达到地下空间综合利用的目的。
