Synchronous grouting construction method for controlling floating of super-large-diameter shield tunnel
The invention discloses a synchronous grouting construction method for controlling floating of a super-large-diameter shield tunnel, which belongs to the technical field of shield construction, and comprises the following steps: respectively mixing inert slurry and cement slurry for double-liquid slurry, and preparing the double-liquid slurry from the cement slurry and water glass according to a volume ratio of 10: 1-12: 1; pumping the mixed inert slurry and the double-liquid slurry into a slurry storage tank in a shield tunneling machine; the multiple grouting pipelines are evenly arranged in the circumferential direction of the shield tunneling machine at intervals, and when the shield tunneling machine starts tunneling, double-liquid slurry is injected into the upper half portion of a segment through the grouting pipelines located on the half of the upper portion of the shield tunneling machine. And meanwhile, the other half of grouting pipelines located on the lower portion of the shield tunneling machine are used for synchronously injecting inert grout into the lower half portion of the segment.
本发明公开了一种控制超大直径盾构隧道上浮的同步注浆施工方法，属于盾构施工技术领域，包括如下方法步骤：分别拌制惰性浆液和用于双液浆的水泥浆液，并将所述水泥浆液和水玻璃按照体积比为10:1～12:1配制所述双液浆；将拌制好的所述惰性浆液和所述双液浆泵送至盾构机内储浆池；若干所述注浆管路沿盾构机圆周周向均匀间隔设置，在盾构机开始掘进时，利用位于盾构机上部的一半数量的所述注浆管路向管片的上半部分注入双液浆，同时利用位于盾构机下部的另一半数量的所述注浆管路向管片的下半部分同步注入惰性浆液。
