Shield construction method for subway underneath passing highway
The invention discloses a subway underneath passing highway shield construction method which comprises the steps that a shield tunneling machine is adopted to conduct tunneling in a rock-soil layer until the distance between the shield tunneling machine and a highway is not smaller than 12-15 m, the posture of the shield tunneling machine is corrected in multiple times, and the posture requirement of a designed tunneling path is met when the shield tunneling machine conducts tunneling to the position 12-15 m away from the highway; starting from the position 12-15 meters away from the highway, the tunneling speed of the shield tunneling machine is controlled to be 30-50 mm/min, the thrust is controlled to be 12000-15000 KN, and the torque is controlled to be 2000-3000 KN. M; and the shield tunneling machine is tunneled to penetrate through the highway and is tunneled to a position which is not less than 12 meters away from the highway. The method has the advantages that disturbance to surrounding soil can be effectively reduced, land subsidence can be effectively controlled, safety is high, construction is easy and convenient, and operation, popularization and implementation are easy.
本发明公开了一种地铁下穿高速路盾构施工方法，包括采用盾构机在岩土层掘进至达到距离高速路不小于12～15米的一段区间段内，分多次对盾构机的姿态进行纠偏，使盾构机在掘进至距离高速路12～15米的位置处时符合设计掘进路径的姿态要求；从距离高速路12～15米的位置开始，盾构机的掘进速度控制在30～50mm/min，推力控制在12000KN～15000KN，扭矩控制在2000KN·m～3000KN·m；直至盾构机掘进穿过高速路且掘进到距离高速路的距离不小于12米位置的步骤。本发明具有能够有效降低对周围土体的扰动和控制地面沉降、安全性高、施工简单方便、易于操作和推广实施等优点。
