Swivel beam structure construction technology

Abstract

The invention provides a swivel beam structure construction technology, and belongs to the technical field of swivel beam construction.The swivel beam structure construction technology comprises the following steps that S1, a spherical hinge, a sliding way, a lower rotating disc, an upper spherical hinge, an upper bearing platform and a traction steel strand are sequentially constructed and installed; s2, continuous beam construction comprises 0 # block construction, continuous beam symmetrical section hanging basket suspended casting construction, side span support cast-in-place section construction, rotation traction construction, closure section construction and prestress construction; s3, a welding power source is configured firstly, then construction materials are prepared, then the steel formwork is hoisted in a segmented mode, and welding is conducted after hoisting of the steel formwork is completed; and S4, the protection wall, the vertical wall and the beam body are connected into a whole, then curtain board prefabrication installation, handrail installation, cable trough cover plate construction, expansion joint installation and contact net supporting column foundation construction are conducted in sequence, and the technology is convenient to construct, high in safety and low in construction cost.

Description

technical field [0001] The invention relates to a swivel beam construction technology, in particular to a swivel beam structure construction technology. Background technique [0002] Because the railway bridge crosses the existing railway line, the construction risk and construction difficulty are high, the safety protection requirements are strict, the technical difficulty is relatively large, and the construction takes a long time, which affects the overall construction period, especially in some hillside areas, the terrain drop is large, which is not conducive to the construction. . SUMMARY OF THE INVENTION [0003] In order to make up for the above deficiencies, the present invention provides a construction technology of a swivel beam structure, aiming at improving the problems raised in the above background technology. [0004] The present invention is achieved in this way: a construction technology for a swivel beam structure, comprising the following steps [0005...
