Installation method of steel box tied arch bridge
The invention relates to the technical field of bridge engineering, and provides a mounting method of a steel box tied arch bridge, which comprises the following steps of: firstly, filling a first construction platform on a bank of a river channel; a first main pier and a plurality of first main beam lattice piers are arranged on the first construction platform; and first main longitudinal beams are mounted on the first main bridge piers and the first main beam lattice piers. And a gantry crane is assembled on the first main longitudinal beam, and a cross beam is installed on the first main longitudinal beam through the gantry crane. The main longitudinal beam construction platform of the first construction platform is removed, and a second construction platform is filled on the other bank of the river channel; a second main pier and a plurality of second main beam lattice piers are arranged on the second construction platform; and second main longitudinal beams are installed on the second main bridge piers and the second main beam lattice piers, and the second main longitudinal beams and the first main longitudinal beams are connected to form the main bridge. And a gantry crane is used for installing a cross beam on the second main longitudinal beam, meanwhile, the second construction platform is removed, and after the cross beam is installed, the gantry crane is removed. The problems of large investment, high cost, low efficiency and the like of a traditional installation method are solved.
本发明涉及桥梁工程领域技术领域，提供了一种钢箱系杆拱桥的安装方法，包括如下步骤：先在河道一岸填筑第一施工平台；在第一施工平台上设置第一主桥墩以及若干第一主梁格构墩；在第一主桥墩和若干第一主梁格构墩上安装第一主纵梁。在第一主纵梁上拼装龙门吊，使用龙门吊在第一主纵梁上安装横梁。清除第一施工平台的主纵梁施工平台，在河道另一岸填筑第二施工平台；在第二施工平台上设置第二主桥墩以及若干第二主梁格构墩；在第二主桥墩和若干第二主梁格构墩上安装第二主纵梁，第二主纵梁与第一主纵梁连接成主桥梁。使用龙门吊在第二主纵梁上安装横梁，同时清除第二施工平台，待横梁安装结束后，清除龙门吊。解决了传统安装方法投入大，成本高、效率低等问题。
