Large-span steel structure combined bridge construction method
The invention discloses a construction method of a large-span steel structure combined bridge. The construction method comprises the steps that S1, a truck crane is arranged near each of two piers; s2, a main truck-mounted crane is connected with the middle of the steel beam component, the main truck-mounted crane lifts the steel beam component, one end of the steel beam component is located between the first pier and the second pier, and then the steel beam component is borne on the first pier; s3, the auxiliary truck crane is connected with the end, close to the steel beam component, of the steel beam component, then the main truck crane is separated from the middle position of the steel beam component, and then the main truck crane is connected with the other end of the steel beam component; s4, the main truck crane and the auxiliary truck crane hoist the steel beam component and enable the steel beam component to be installed on the first bridge pier and the second bridge pier; and S5, the steps S2 to S4 are repeated, hoisting of all the steel beam components is completed, and finally all the steel beam components are spliced. According to the construction method of the large-span steel structure combined bridge, hoisting construction can be conducted on the large-span steel structure combined bridge through a common truck crane, and construction is more convenient.
本发明公开了一种大跨度钢结构组合桥梁施工方法，包括：S1.在两个桥墩的附近均布置一台汽车吊；S2.将主汽车吊连接钢梁构件的中部，主汽车吊对钢梁构件进行吊运，使钢梁构件的一端位于第一桥墩和第二桥墩之间，之后使钢梁构件承载于第一桥墩上；S3.将辅汽车吊与钢梁构件相靠近的一端连接，然后将主汽车吊与钢梁构件的中部位置分离，之后将主汽车吊与钢梁构件的另一端连接；S4.主汽车吊和辅汽车吊吊运钢梁构件并使钢梁构件安装于第一桥墩和第二桥墩上；S5.重复步骤S2至S4，完成所有钢梁构件的吊装，最后将所有钢梁构件进行拼接。本发明实施例的大跨度钢结构组合桥梁施工方法，利用普通的汽车吊即可对大跨度钢结构组合桥梁进行吊装施工，施工更加方便。
