Active reinforcement combined control method for settlement of shield machine closely attached to and underneath passing existing station
The invention relates to the related technical field of subway construction, in particular to an active reinforcement combined control method for settlement of a shield closely attached to an underneath pass existing station. The active reinforcement combined control method for settlement of the shield closely-attached underpass existing station comprises a construction preparation process before crossing, a process of determining an emergency bin-opening tool inspection point before wall grinding of a shield tunneling machine, a test section trial tunneling process, a crossing section control process, a post-stagnant settlement control process after crossing and a receiving end diaphragm wall chiseling process. The backfill grouting is used for shield tunneling construction, so that a shield tail gap can be filled in time, ground surface subsidence is avoided, underground water is prevented from leaking and entering a duct piece, a disturbed soil layer in excavation can be stabilized as soon as possible, and snaking of a tunnel and deformation of the duct piece of the tunnel are prevented.
本发明涉及地铁施工相关技术领域，具体为一种盾构密贴下穿既有站沉降主动加固联合控制方法，盾构密贴下穿既有站沉降主动加固联合控制方法包含穿越前施工准备过程、盾构机磨墙前应急开仓检刀点确定过程、试验段试掘进过程、穿越段控制过程、穿越后后滞沉降控制过程和接收端地连墙凿除过程；盾构掘进施工使用壁后注浆之可及时填充盾尾间隙避免导致地表沉陷，防止地下水渗漏进入管片内，使开挖受扰动之土层能及早稳定，防止隧道蛇行，及防止隧道管片变形。
