Jack-in erection equipment for bridge

Abstract

The invention relates to jack-in erection equipment for a bridge, which comprises a jacking device, a synchronous jacking and adjusting system, a jack-up device, a synchronous jack-up and adjusting system, limiting devices, a skid beam and a bearing beam, wherein the jacking device is arranged between a box girder to be erected and the bearing beam and is parallelly fixed on the skid beam; the synchronous jack-up and adjusting system is arranged on one side of the jacking device; the jack-up device is fixed on the bearing beam; the synchronous jack-up and adjusting system is arranged is arranged below the jacking device; the limiting devices are arranged on both sides of the skid beam; the skid beam is arranged below the box girder; and the bearing beam is arranged on a bridge pier. Compared with the prior art, the jack-in erection equipment is portable, and the system is simple and easy to install; and the application optimization of combining subjects in a comprehensive field and the logic control technology is utilized and a reasonable technical route of control procedures is developed through synergistic coordination, so that the system equipment is simplified, and the degree of automation is improved greatly.

Description

technical field [0001] The invention relates to erection of long-span bridges, high-speed railways and expressways, in particular to a bridge pushing erection equipment. Background technique [0002] The jacking method construction of bridges, etc. is to use a special jacking force device during construction to push the beam body to move on the special supporting facilities and sliding devices, and finally push the beam body to the planned erection position. Compared with the traditional construction method, the biggest advantage of the jacking method is that the approach bridge on the shore can be used as a jacking platform for construction. The jacking erection process does not affect the navigation of the river and does not require heavy hoisting and bridging equipment. It is especially suitable for occasions where large-scale hoisting equipment cannot be stationed in construction or large-scale floating crane construction is not suitable. [0003] The bridge to be erect...

AI Technical Summary

Problems solved by technology

[0008] According to relevant searches, there are very few large-scale bridges that have been built using the jack-up construction technology of the same type of bridges at home and abroad. Only the French Millau Bridge completed in 2005 in foreign countries belongs to the similar jack-up bridging technology. The construction of the French Millau Bridge is a bridge built between the Grand Canyon. In terms of overall design, system settings and working principles, the overall technology of the French Millau Bridge is much more complicated and complicated. The whole set of equipment and The system is extremely expensive, and each part requires multiple people to work together to achieve the process construction requirements
