Construction method of inclined cable tower construction structure system

Abstract

The invention relates to a construction method of an inclined cable tower construction structure system, which comprises the following steps of: 1) construction preparation; 2) arrangement of a combined support frame and a combined grid frame; 3) binding of cable tower steel bars; 4) installation of a tower cable guide pipe; 5) construction of a sliding moulding plate; 6) arrangement of a groutingguide pipe; and 7) concrete maintenance construction of the cable tower. The construction method of the inclined cable tower construction structure system has the advantages that arrangement efficiency of the combined support frame and the combined grid frame can be improved, integrity of the structure can be enhanced, and supporting quality of the sliding moulding plate can be effectively improved; positioning of the cable tower steel bars is accurate, connection is convenient, binding construction quality of longitudinal steel bars and transverse stirrups can be effectively improved, and on-site construction difficulty is reduced; and on-site arrangement of the concrete grouting guide pipe is convenient, an inclination angle of the grouting guide pipe can be dynamically adjusted according to an inclination condition of the cable tower, on-site positioning difficulty is reduced, and concrete pouring quality is improved.

Description

technical field [0001] The invention relates to a construction method of a cable tower construction structure system that can improve the quality of on-site construction and the integrity of the construction structure, reduce the difficulty of steel cage binding, formwork installation, and tower cable guide positioning, and improve on-site construction efficiency, and belongs to bridge engineering It is applicable to the construction engineering of inclined cable towers. Background technique [0002] The low-tower cable-stayed bridge is a bridge structure between a flexible cable-stayed bridge and a rigid continuous girder bridge. The cable-stayed cables can share the load with the main girder, and have been widely used in bridge engineering construction. However, in the construction of short-tower cable-stayed bridges, problems such as precise positioning of formwork, fast binding of steel cages, efficient and environmentally friendly concrete pouring, and accurate position...
