Beam body dismounting and mounting method for large-span slope bridge
The invention discloses a beam body dismounting and mounting method for a large-span slope bridge in the technical field of bridge dismounting and mounting, which comprises the following steps: S1, selecting three cranes, and stably arranging the cranes at the slope top and the slope bottom respectively, and S2, erecting the crane at the slope bottom at a first pier; the method comprises the steps of S1, hoisting a beam body through a high-point crane and a second crane, S2, hoisting the beam body through the high-point crane and the second crane, S3, hoisting the beam body through the high-point crane and the second crane, S4, using the first crane in the midway, S5, and stably dismounting the beam body, and S6, carrying out mounting operation, hoisting the beam body through the first crane and the second crane, S4, using the high-point crane in the midway, and S5, and stably mounting the beam body. Operation can be completed through three small cranes, the requirements for the lifting environment and a supporting platform are low, the beam body outside the arm rod extending range can be lifted, disassembled and assembled in an air relay mode, the operation stability is high, the transverse moving stability of the beam body is high, and the balance is better when the beam body is lifted through the two cranes.
本发明公开了桥梁拆装技术领域的一种大跨度坡面桥梁的梁体拆装方法，包括步骤S1，选取三台吊机，分别在坡顶和坡底稳定安置，步骤S2，将坡底的吊机架设在一号桥墩处；步骤S3，拆除操作，将梁体通过高点吊机和二号吊机起吊，步骤S4，中途转用一号吊机，步骤S5，并将梁体稳定拆除，骤S6，安装操作，将梁体通过一号吊机和二号吊机起吊，步骤S4，中途转用高点吊机，步骤S5，并将梁体稳定安装，能够通过本方法的改进，使用三台小型吊机即可完成操作，对起吊环境和支撑平台需求低，并且通过空中接力的方式，能够将臂杆伸出范围以外的梁体进行起吊拆装，操作的稳定性强，梁体横移的稳定性强，两台吊机对梁体吊装时平衡性更佳。
