Abstract

The invention discloses a fast construction method for a cable-stayed bridge cable tower structure system, and relates to the technical field of bridge construction. The fast construction method of the cable-tower structural system of the cable-stayed bridge comprises: step 1, constructing the base section of the tower column; step 2, assembling the steel beams between the tower column sections and the tower column sections; Install the stay cables on the steel beams; step 4, construct the corresponding main beam section based on the installed stay cables; repeat step 2‑4 until the tower columns are capped and the main beams are all constructed. In the embodiment of the present invention, steel beams are used to establish the transverse connection between the tower column segments between each section of the tower column segments, which improves the structural stability of the cable-stayed bridge cable tower, and can anchor the tower column side of the cable-stayed cable to the On the steel beams, the structural stability requirements during the construction of the tower columns can be reduced, and the construction of the stay cables and the corresponding main beam sections can be started during the construction of the tower columns, realizing the simultaneous construction of the tower columns, stay cables, and main beams, which is extremely Greatly reduce construction time and improve work efficiency.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a rapid construction method for a cable-stayed bridge cable tower structure system. Background technique [0002] With the rapid development of road traffic, the demand for long-span and larger-span bridges continues to increase. As an important bridge type of long-span bridges, cable-stayed bridges have attracted much attention in the anchorage area of ​​cable towers, which are important stress structures. The anchorage area of ​​the cable tower is a structure that uniformly transmits the local concentrated force of the stay cable to the lower part of the cable tower. [0003] Commonly used cable-stayed bridge towers include single-column, double-column, A-style, inverted Y-style, portal, vase, diamond, pagoda, etc. There is no or 1 to 2 beams on the upper tower section. The existing cable-stayed cable tower end anchorage methods are as follows: prestres...
