Description
Technical Field
The utility model relates to the technical field of bridge engineering construction, in particular to an integrated overhead portal of a space cable surface suspension bridge.
Background
Suspension bridges are bridges with cables suspended by cable towers and anchored at both sides or ends of the bridge as the main load-bearing members of the superstructure. The main cables of the suspension bridge are generally arranged in a parallel cable plane mode, namely, the distance between the transverse directions of the two main cables is a fixed value, and the cable carrying crane is arranged on the two main cables during construction, so that the subsequent main beams can be hoisted. However, some main cables of the suspension bridge adopt a space cable surface arrangement form, that is, the distance between two main cable transverse bridge directions is a variable value, the distances between the main cable transverse bridge directions are different from the bridge tower to the midspan position, the cable-carried crane is not applicable to the suspension bridge with the space cable surface, and the space cable surface suspension bridge is usually provided with steel structure tower columns at two banks or the bridge tower and is provided with the cable crane for completing the hoisting of the subsequent main girder. This method of separately providing a tower mounted cable crane at both sides or pylons has the following problems.
1. The arrangement of the steel tower columns on the two sides can greatly increase the span of the cable crane and increase the consumption of the steel wire rope; the steel tower column needs to be installed from the ground until the height is higher than that of the bridge main tower, and the consumption of the steel structure is large; this practice adds a significant amount of temporary equipment costs and is economically disadvantageous.
2. The steel tower column is high, and the installation is loaded down with trivial details, and construction cycle is long, and installs and tears open and has great potential safety hazard in the use.
