Abstract

The invention discloses a swivel system for long-span continuous beam span existing station swivel construction and a construction method. The swivel system comprises a lower supporting disk, an upper rotating disk, a bridge swivel spherical hinge mounted between the lower supporting disk and upper rotating disk and a swivel traction system driving the upper rotating disk to rotate, wherein the lower supporting disk and the upper rotating disk are each of a reinforced concrete structure and are both arranged horizontally, and the swivel traction system is connected with the upper rotating disk; multiple supporting legs are arranged at the bottom of the upper rotating disk, and an annular slide way where the supporting legs slide is arranged on a lower bearing table. The construction method of the swivel system comprises the steps of erection of a lower bearing table forming formwork, concrete pouring construction of a bottom bearing table, installation of a lower spherical hinge and the annular slide way, concrete pouring construction of an upper bearing table, hoisting of an upper spherical hinge, installation of the supporting legs, erection of an upper rotating disk forming formwork and concrete pouring construction. The swivel system is reasonable in design, easy and convenient to construct and good in use effect, the swivel construction process of a long-span continuous beam can be completed easily and conveniently, and the swivel process is stable.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a swivel system and a construction method for swivel construction of existing stations with long-span continuous beam spans. Background technique [0002] At present, China's railway construction is in a golden period, and a large number of passenger dedicated lines and intercity railways have started and put into use one after another. The special technical requirements of passenger dedicated lines make it impossible to use level crossings like ordinary railways. What followed was an increase in the construction of the passenger dedicated line across the existing main railway lines, railway stations, and highways. The construction period for crossing is long, which has a great impact on the operation of the business line and highlights potential safety hazards. [0003] The bridge swivel construction is to use the ball joint with a small friction coeffic...
