Problems solved by technology
[0003] In the above-mentioned construction process, since the tower is assembled in vertical segments, a large tower crane is required, which makes the construction difficult; and because the installation of the tower with slings needs to rely on the side-span steel arch ribs and mid-span steel arch ribs on both sides. For the arch rib, the sling tower can only be assembled after the construction of the side-span steel arch rib and mid-span steel arch rib is completed. Therefore, installing the sling tower in this way takes a long construction period of the main structure, which makes the construction period of the bridge long and the cost is high

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0023] see figure 1 and figure 2 As shown, the embodiment of the present invention provides a method for installing a sling tower, including the following steps:
[0024] S1: After the construction of the side-span steel arch rib 1 is completed, the sling tower 2 is assembled section by section along the longitudinal bridge direction on the side-span steel arch rib 1, and the middle-span steel arch rib 4 is installed, and the side-span steel arch rib 1 Install the base 3 at a position close to the mid-span steel arch rib 4, and hinge one end of the sling tower 2 to the base 3;
[0025] S2: After the sling tower 2 is assembled, the front sling 5 extending to the mid-span steel arch rib 4 and the rear sling 6 extending to the side-span steel arch rib 1 are installed on the other end of the sling tower 2, The cable crane lifts the sling tower...

The invention discloses a method for installing a cable tower and relates to the field of bridge construction. The method includes the steps that 1, after sidespan steel arch rib construction is completed, the cable tower is assembled section by section on a sidespan steel arch rib in the longitudinal direction of a bridge, a midspan steel arch rib is installed, a base is installed in the position, close to the midspan steel arch rib, of the sidespan steel arch rib, and one end of the cable tower is connected with the base; 2, after the cable tower assembly is completed, a front hoist cable and a rear hoist cable are installed at the other end of the cable tower, wherein the front hoist cable extends toward the midspan steel arch rib and the rear hoist cable extends toward the sidespan steel arch rib, and a cable lifting machine lifts the cable tower and makes the cable tower rotate to a vertical state; 3, the front hoist cable and the rear hoist are stretched, the front hoist cable is connected with the midspan steel arch rib, the rear hoist cable is connected with the sidespan steel arch rib, and the installation of the cable tower is completed. According to the method for installing the cable tower, the construction is simple, the installation is convenient, and the cost is saved.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a method for installing a suspension tower. Background technique [0002] Suspension towers play a pivotal role in the cantilever construction of steel truss arch bridges and steel truss girders. The steel arch rib and the steel beam node of the mid-span steel arch rib are assembled vertically and segmentally into the suspension tower, and temporary wind cables are set on both sides of the tower during the assembly process to connect the side-span steel arch rib The mid-span and mid-span steel arch ribs are all connected to the tower to enhance the stability and wind resistance of the sling tower during assembly. [0003] In the above-mentioned construction process, since the tower is assembled in vertical segments, a large tower crane is required, which makes the construction difficult; and because the installation of the tower with slings needs to rely on the side-span steel...
