Subway shield underneath passing high-speed rail bridge anti-disturbance construction structure and construction method
According to the subway shield underneath passing high-speed rail bridge anti-disturbance construction structure and the construction method, an isolation curtain is arranged between a subway tunnel and an adjacent bearing platform, and the influence of subway tunnel shield construction on a high-speed rail bridge is reduced through the isolation curtain; an anti-settlement arch frame and an anti-settlement pile are arranged between the isolation curtains, the anti-settlement pile is fixedly connected with the anti-settlement arch frame, an anti-settlement area is formed in the stratum on the upper portion of the subway tunnel, the anti-settlement area reduces soil layer pressure loss after subway tunnel shield excavation, more grout can be injected into a gap between the tail portion of the shield and a duct piece in a pressurized mode, and therefore the anti-settlement effect is achieved. The soil layer loss caused by the metro tunnel shield overexcavation gap can be better filled, so that the adverse effect on the high-speed railway bridge caused by ground subsidence in the construction of the metro shield underneath passing the high-speed railway bridge is solved.
一种地铁盾构下穿高铁桥梁抗扰动施工结构及施工方法，在地铁隧道与相邻承台之间设置隔离帷幕，通过隔离帷幕降低地铁隧道盾构施工对高铁桥梁的影响；在隔离帷幕之间设置抗沉降拱架、抗沉降桩，抗沉降桩与抗沉降拱架固定连接，在地铁隧道上部地层中形成抗沉降区，抗沉降区降低了地铁隧道盾构开挖后的土层压力损失，使盾构尾部与管片之间的空隙可以加压注入更多的浆液，更好填补地铁隧道盾构超挖间隙造成的土层损失，从而解决地铁盾构下穿高铁桥梁施工中地面沉降对高铁桥梁造成的不利影响。
