Abstract

The invention relates to the field of bridge engineering foundation structures. The invention provides a cable tower structure and a construction method thereof. The cable tower structure includes: two sets of caisson pile foundation groups, each group of caisson pile foundation groups includes more than two caisson pile foundations, Each caisson pile foundation is provided with a cap, and the adjacent caisson pile foundations in each group of caisson pile foundation groups are fixedly connected by tie beams. It also includes two inverted Y-shaped pylons that are fixedly connected to each other, each pylon includes multiple pylon segments spliced ​​in sequence, and the lower end of each pylon is connected to the outer side of one of the caisson pile foundations. The two caps are fixedly connected. The invention can solve the problem of increasing the cross-sectional area along the bridge direction in order to meet the large load-carrying requirements of the cable tower structure, resulting in an increase in the self-weight of the cable tower and an increase in the foundation cost of the cable tower.

Description

technical field [0001] The invention relates to the field of bridge engineering infrastructure, in particular to a cable tower structure and a construction method thereof. Background technique [0002] The cable tower structure of the bridge uses the cable system to support the beam structure across waters, canyons and other geographical transportation obstacles. In cable-stayed bridges, suspension bridges and other cable-supported bridge structure systems, the cable towers are very high, and even if the horizontal load of the beam structure at the lower position of the action point is transferred to the higher position of the cable tower through the action of the cable system In the position, the bending moment load borne by the cable tower structure is very large. [0003] In the existing bridge technology, the cable tower structure is generally constructed of reinforced concrete, and there are also a few examples of steel structure and steel tube concrete structure used ...
