Bridge double-door type beam hoisting and replacing method
The invention discloses a bridge double-portal crane beam replacing method. The method comprises the following steps that S1, two portal cranes are arranged on a bridge and at the two ends of a target beam correspondingly; s2, the two gantry cranes are used for hoisting the target beam and enabling the target beam to incline to enable the second end of the target beam to be higher than the first end of the target beam; and S3, the inclined target beam is lowered from the gap between the two piers of the bridge and the gap between the two beams on the two sides of the target beam. According to the bridge double-door type beam lifting and replacing method, the gantry crane is erected on the bridge, the target beam is inclined, and therefore the target beam is detached through the gaps between piers of the bridge and between the two beams on the two sides of the target beam, the target beam is detached, roads below the bridge do not need to be excessively occupied, a large amount of occupied bridge floor is reduced, and the construction cost is reduced. And the influence on urban traffic is reduced.
本发明公开了一种桥梁双门式吊换梁方法，其包括如下步骤：S1、将两台门吊分别设置在桥梁上、目标梁的两端；S2、利用两台所述门吊，吊起所述目标梁并使得所述目标梁倾斜成所述目标梁的第二端高于所述目标梁的第一端；S3、将倾斜的所述目标梁从桥梁的两个桥墩之间、所述目标梁两侧的两个梁之间间隙中下放。该桥梁双门式吊换梁方法在桥梁上架设门吊，倾斜目标梁，从而利用桥梁的桥墩之间、目标梁两侧的两个梁之间的间隙，将目标梁拆下，实现目标梁的拆卸，从而不必过度占用桥梁下方的道路，也减小了对桥梁桥面的大量占用，降低了对城市交通的影响。
