Embodiment Construction
[0036] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as Figure 1 to Figure 7 Shown: a construction method of a two-way inclined V-shaped bridge tower of a cable-stayed bridge without back cables, which is carried out in sequence according to the following steps: construction preparation, installation of rigid skeleton and positioning of cable guides, construction of lower tower columns, assembly of hydraulic climbing modules, and Simultaneous construction of tower columns and towers in the cable area, construction of the closing section of the tower top and removal of formwork and cross braces,
[0037] The synchronous construction steps of the tower column and cable tower in the cable area are composed of four steps: pouring concrete in sections, tensioning prestress, tensioning cable stays, and erecting brackets and cross braces.
[0038] The construction preparation steps are as follow...
