Abstract

The invention discloses a small-angle oblique steel arch tower without a support in-situ assembly type asymmetric tension assembly construction method, which is to change the traditional support method erection process into a support-free assembly in the construction stage of bridge steel arch tower erection process, the quality of the steel arch tower is controllable; in addition, it also reduces the difficulty of construction, saves the amount of auxiliary measures such as lifting equipment, temporary supports and assembly sites, shortens the construction period, reduces costs, and ensures the passage of the waterway. convenient. The invention provides a small-angle oblique steel arch tower without support in-situ assembly type asymmetrical tension assembly construction method, which realizes the industrial production, transportation, hoisting and positioning of the steel arch tower, and solves the problem of limited working space and construction period of the bridge construction. It is a construction problem that is tight and crosses a river with navigable requirements.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a small-angle oblique steel arch tower without support in-situ assembly type asymmetrical tension assembly construction method, which is especially suitable for limited working space, tight construction period, and double-sided cable-stayed cables. Installation and construction of symmetrically tensioned steel arch towers. Background technique [0002] As a structural form of bridge tower, oblique steel arch tower has the advantages of clear structural force, novel design, and beautiful architectural appearance. It is often used in some bridges spanning highways, rivers and municipalities. At present, the construction methods of steel arch tower girder bridges mostly rely on external facilities such as brackets, follow the symmetry of the left and right tower columns, assemble from the bottom to the top of the tower in turn, and realize the method of closi...
