Utilization method of existing bridge rotation

Abstract

The invention discloses a swivel utilization method of an existing bridge. At least two sets of vehicle-mounted equipment support beams are arranged laterally along the direction of the bridge, and the vehicle-mounted equipment sets drive the beams to rotate around the rotation center to a designed position. Aiming at the problem that the existing overpass bridge must be dismantled and rebuilt in the reconstruction and expansion of the expressway, the present invention proposes an existing bridge swivel utilization method and its vehicle-mounted equipment under the operating conditions of the existing expressway and its oblique bridge, which can be fully realized The comprehensive effect of safety, greenness, economy, speed, and low traffic impact is in line with the development concept of innovation, coordination, greenness, openness, and sharing, and has significant economic value and social benefits.

Description

technical field [0001] The invention relates to the field of bridge construction. More specifically, the present invention relates to a method for utilizing the existing bridge swivel. Background technique [0002] After the expressway is reconstructed and expanded, 2 or 4 lanes need to be added. The upper span bridges (pedestrian bridges, vehicle bridges, aqueducts, ramp bridges, overpasses, etc.) that cross the expressway are often changed because the original roadside piers occupy the widened lanes. Need to demolish and rebuild. In the traditional highway reconstruction and expansion project, the demolition of the over-line bridge generally adopts direct chiseling, blasting demolition, erection of supports + cutting and hoisting removal or segmental cutting and removal of vehicle-mounted supports under fully enclosed or half-closed conditions. Some of them are mostly removed by direct chiseling and cutting and lifting. Reconstruction construction mostly adopts the stru...

AI Technical Summary

Problems solved by technology

The road-related demolition and construction of this type of bridge has a great impact on the traffic of the expressway (it takes a long time for the road construction), the construction and traffic organization are complicated, and the safety, traffic, progress and environmental protection problems are prominent, which can no longer meet people's expectations for a better life in the new era. The yearning demand and the establishment of a sound economic system for green, low-carbon and circular development
