Abstract

The invention provides a steel box girder bridge erecting machine with a small curve radius and a construction method for erecting it, comprising a main beam of the bridge erecting machine, a front outrigger device arranged at the front end of the main beam of the bridge erecting machine, and a rear outrigger arranged at the rear end of the bridge erecting machine device, the middle outrigger device installed near the rear end of the main girder of the bridge erecting machine, and the middle outrigger traversing track arranged along the transverse bridge direction, the bottom of the middle outrigger device is installed on the middle outrigger traversing track through the middle leg sliding block ; The main girder of the bridge erecting machine is provided with a front crane 16 and a rear crane 17. When the sliding block of the middle outrigger on the moving track moves the middle outrigger, the beam tail of the main girder of the bridge erecting machine will also move accordingly, and the rotation angle of the bridge erecting machine can be adjusted, so that the whole machine of the bridge erecting machine can be adjusted. The posture is adjusted to the erection posture of the steel box girder, so that the steel box girder erected by the bridge erecting machine with this posture is the set steel box girder posture, which is suitable for the erection of small curve radius steel box girders.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a steel box girder erecting machine with small curve radius and an erecting construction method. Background technique [0002] With the rapid development of my country's economy, the number of bridges is also increasing. In order to shorten the construction period of bridges, give full play to the characteristics of materials, and improve economic and social benefits, steel box girder bridges have gradually become one of the important forms of bridge structures. At the same time, due to the environmental complexity, functional diversity, and linear complexity of the steel box girder bridge construction, it has a great impact on the installation and construction of the steel box girder, especially to solve the problem of the steel box girder under the small curve radius. erection problem. [0003] For example, steel box girders are used for the 5th to 7th j...
