Cable saddle transverse moving system and cable saddle transverse moving construction method

Abstract

The invention discloses a cable saddle transverse moving system and a cable saddle transverse moving construction method. The cable saddle transverse moving system is characterized in that a pulley block is installed on a steel cable between a cable saddle flatcar and a steering seat, a small-diameter steel cable which is connected with the pulley block and a hoist is wound through the steering seat to enable the steel cable to pass through the steering seat more easily, the contact area between the steel cable and the steering wheel of the steering seat is reduced, the friction between the steel cable and the steering wheel of the steering seat is reduced, the wear caused by the friction between the steel cable and the steering wheel of the steering seat is reduced and the risk that the steel cable is broken due to the wear is reduced. The cable saddle transverse moving construction method is characterized in that a ship is used for transporting arch rib sections; after the ship reaches a position right below the installation position of the arch rib sections, the body of the ship is stopped, anchored and fixed along the water flowing direction of a river, only the head or the tail of the ship is under the impact of water flow, the impact of the water flow to the body of the ship is reduced, and the ship can realize the transportation and the hoisting of the arch rib sections in a raging river channel without being turned over from one side.

Description

technical field [0001] The invention belongs to the field of bridge construction engineering, and in particular relates to a cable saddle traversing system and a cable saddle traversing construction method. Background technique [0002] In the construction of bridges, especially in the construction of arch bridges, because the cable crane is not restricted by factors such as climate and terrain, the cable hoisting construction method is widely used in the current bridge construction, and it is also the current long-span arch bridge in my country without supports. The main method of construction. The so-called cable hoisting construction method is to install a cable saddle on the top of the two towers, and install a steel cable between the cable saddles, use the steel cable as a load-bearing structure, and use a trolley to move back and forth on the load-bearing steel cable to hoist the arch rib segment. . In order to realize the hoisting of arch ribs with different axes, th...

Problems solved by technology

At this time, the hull of the ship is lying across the river or the river, so that the ship is in a state where one side of the hull is impacted. In the turbulent river, it is very easy to cause the hull to capsize, thereby causing major engineering accidents. Therefore, there is an urgent need for a Safe hoisting construction method of arch rib
