A hoisting method of a bridge deck hoisting device for an H-type dual-purpose bridge

Abstract

The invention provides an H-shaped combined highway and railway bridge deck slab lifting device and method and belongs to the technical field of road bridge construction. The device comprises two girders and two crossbeams. The girders are fixedly connected through the crossbeams and stretch across two adjacent piers. The first pier is arranged below the left side of the girders. The second pier is arranged below the right side of the girders. A highway bridge floor is arranged above the first pier. A hydraulic tail supporting leg and a girder moving mechanism are arranged above the highway bridge floor and on the girders. A girder moving mechanism is arranged above the second pier and on the girders. A front traveling crane and a rear traveling crane are further arranged between the two girders. When railway bridge deck slabs are laid, a beam channel is obliquely lifted, and the needed lifting space of the beam channel is greatly reduced. Operation is convenient in the whole lifting process, lifting efficiency is high, the construction workload and construction cost are reduced, and the paving schedule is quickened.

Description

technical field [0001] The invention belongs to the technical field of road and bridge construction, and in particular relates to a hoisting method of an H-type road-rail dual-purpose bridge deck hoisting device. Background technique [0002] Due to its unique structural characteristics, the highway dual-purpose bridge allows the joint operation of highways and railways, which not only saves resources, but also obtains great economic benefits. It is very common in bridge construction. The piers of road-rail dual-purpose bridges are generally H-shaped, the upper girder of the bridge pier is longer, and the lower beam of the bridge pier is shorter than the upper girder, but the difference is not too big. In the process of laying channel girders of railway bridges, when the size of the channel girders is long, the hoisting space is very limited. In particular, when the first channel beam is laid, due to the obstruction of the first channel beam, the hoisting space of the secon...

Problems solved by technology

In the process of laying channel girders of railway bridges, when the size of the channel girders is long, the hoisting space is very limited

In particular, when the first channel beam is laid, due to the obstruction of the first channel beam, the hoisting space of the second channel beam is even narrower, which is very inconvenient and difficult to hoist, which increases the construction workload and construction costs
