Method for erecting bridge body

Abstract

The invention relates to the technical field of bridge construction, in particular to a method for erecting a bridge body. The method for erecting the bridge beam body comprises the following steps that firstly, a beam transporting machine moves to a beam yard to transport multiple sections of prestressed beam bodies, the multiple sections of prestressed beam bodies are continuously erected on piers, a foundation bridge deck is formed by the multiple sections of prestressed beam bodies, and the distance between the foundation bridge deck and the erected beam bodies is the length of two sections of beam bodies; 2, a bridge girder erection machine and a girder transporting vehicle are placed on a foundation bridge deck, and the foundation bridge deck serves as an erection starting point of a section bridge; and thirdly, the beam transporting machine is moved to the area, where the beam bodies are stored, of the beam yard, and a section of prestressed beam bodies are transported to the position above the beam transporting vehicle from the beam yard. The method for erecting the bridge beam body and the beam transporting machine can be used for transporting the beam body to a line from a beam yard and lifting the beam body to the beam transporting vehicle on the bridge from the position below the bridge, can meet the transporting requirement of the bridge beam body in the prefabrication process in the beam yard, meanwhile has the function of erecting the beam body on the bridge pier, and plays a role in integrating carrying, lifting and erecting.

Description

technical field [0001] The present disclosure relates to the technical field of bridge construction, and in particular, to a method for erecting a bridge beam body. Background technique [0002] In the construction of railway transportation infrastructure, bridge construction is often the key control project of the entire construction project. In particular, the high-speed railway bridges in my country account for a large proportion of the entire construction line. The total length of the high-speed railway bridges currently built and under construction accounts for more than 50% of the line length on average. more than 80%. [0003] In order to improve the prefabrication level and construction efficiency of high-speed railway bridge construction, my country's high-speed railway bridges generally adopt prestressed concrete simply supported box girder and prefabricated erection construction modes, that is, in relatively concentrated areas of bridges or beside super bridges wi...

AI Technical Summary

Problems solved by technology

[0004] Beam moving machines and beam lifting machines are large-scale construction equipment, and each set is expensive. For small-scale beam yards, the cost of configuring a set of beam moving machines and beam lifting machines is very high, and the beam moving machines and beam lifting machines The utilization rate is very low, resulting in a great waste of resources

After the beam moving machine transports the prestressed concrete box girder to the bridge, the box girder needs to be placed on the ground under the bridge first, the beam moving machine is driven away, and then the beam lifting machine lifts the box girder from the ground to the bridge. The whole process Complex, time-consuming and energy-intensive
