Subway box girder translation construction device and method

Abstract

The invention discloses a subway box girder translation construction device and method, and relates to the field of subway construction. A moving mechanism of the device comprises a moving cross beam,a first sliding block and a second sliding block which are installed on the moving cross beam are symmetrically arranged on the two sides of the moving cross beam, jacking structures used for ascending and descending are arranged at the top end of the first sliding block and the top end of the second sliding block respectively, and a sliding mechanism is arranged at the top ends of the jacking structures. A movable rolling structure is arranged at the lower end of the moving cross beam. The sliding mechanism comprises a transverse sliding way and a longitudinal sliding way which are arrangedin a crossed mode, idler wheel trolleys used for being connected with and driving the box girder to move are installed on the transverse sliding way and the longitudinal sliding way respectively, andsupporting structures are arranged at the two ends of the transverse sliding way and the longitudinal sliding way. The device can translate the box girder to a designed position through adjustment, improves the construction efficiency of the box girder, is convenient to use, can be repeatedly used, and saves a large amount of manpower and material resources. According to the using method of the device, the box girder can be conveniently constructed and translated, and meanwhile translation of the box girder can be stably achieved.

Description

technical field [0001] The invention relates to the field of subway construction, in particular to a subway box girder translational construction device and method. Background technique [0002] With the development of urban subways, large-scale bridges in subway construction are gradually increasing, and long-span box girders are widely used in the design. Install and carry out secondary use, and then install it in place. In the existing translational construction of box girders, the box girders are basically prefabricated in the prefabrication yard first, and then the prefabricated girders are transported to the construction site by a beam transport trolley, and then the box girders are hoisted by bridge erecting machines or large hoisting equipment. At the predetermined position, with the cooperation of the on-site construction personnel, the prefabricated box girder is hoisted at the designed position. During the construction process, the hoisting of the box girder req...

AI Technical Summary

Problems solved by technology

During the construction process, the hoisting of the box girder requires large-scale equipment. At the same time, the hoisting personnel and the on-site construction personnel need to cooperate closely and communicate at any time, so that the box girder can be hoisted and installed to the design position with a bridge erecting machine or large hoisting equipment. With the cooperation of a large number of people, it is troublesome to communicate. At the same time, it takes a lot of time to install. In addition, when encountering high piers or weak soils, special hoisting equipment is required or only bridge erecting machines can be used. It even costs a lot of money to achieve hoisting. It is not conducive to the hoisting construction of the box girder
