Tower foot anchoring structure for assembling tower and tower building method

Abstract

The invention relates to the field of cable hoisting system tower construction, in particular to a tower foot anchoring structure for assembling a tower and a tower building method. The tower foot anchoring structure comprises a beam body component and a plurality of prestressed steel strands, the prestressed steel strands are vertically pre-buried in 0 # blocks, a leveling layer is arranged on the top faces of the 0 # blocks, the beam body component is anchored to the top surface of the leveling layer through the prestressed steel strand, and the beam body component is used for anchoring a tower foot stand column. The tower is installed at the top of the 0 # block, the tower does not need to be installed in an independently arranged area on the ground, a stable foundation is provided for installation of the tower, the effect of fixing the tower is achieved, the tower can adapt to bridge construction in a mountainous area with a steep slope and a deep ravine, meanwhile, a permanent and temporary combined foundation is formed by the 0 # block, the prestressed steel strand and the beam body component, and after the tower is used, the tower can be detached easily, the overall strength of the 0 # block cannot be affected, the leveling layer can serve as a bridge deck structure, and manpower, material resources and time consumed in the tower building process are reduced.

Description

technical field [0001] The invention relates to the field of tower construction of a cable hoisting system, in particular to a tower foot anchoring structure for an assembled tower and a method for building the tower. Background technique [0002] The tower of the cable hoisting system is used for tensioning (supporting) hoisting cables to cooperate with the hoisting of components in bridge construction such as arch bridges, suspension bridges and cable-stayed bridges. The concrete layer of the tower is anchored by pre-embedded bolts to the tower foot column, and then assembled from bottom to top to realize the overall installation of the tower. [0003] However, the towers of the cable hoisting system for bridge construction are often more than 100 meters high, with large volume, large amount of materials, and complicated construction procedures, which require high anchoring effects for the foundation. For bridge construction in mountainous areas with steep slopes and deep ...

Problems solved by technology

[0003] However, the towers of the cable hoisting system for bridge construction are often more than 100 meters high, with large volume, large amount of materials, and complicated construction procedures, which require high anchoring effects for the foundation. For bridge construction in mountainous areas with steep slopes and deep ravines, work in mountain The surface is narrow and the environmental requirements are harsh. Generally, it is impossible to provide an effective working surface for the foundation. There is often no space for pouring a concrete layer with a certain thickness in a certain area, and it cannot provide an anchoring position for the tower. As a result, the tower installation requires a lot of manpower and material resources. and time, affecting the construction progress

[0004] Therefore, there is an urgent need for a technical solution to solve the technical problems of the existing cable hoisting system, which is difficult to fix the tower foot column, consumes a lot of manpower, material resources and time, and affects the construction progress.
