Quick construction method for No. 0 section of prestressed concrete beam type bridge

Abstract

The invention belongs to the technical field of prestressed concrete continuous beam and continuous rigid frame bridge construction in bridge engineering, and particularly relates to a quick construction method for a No. 0 section of a prestressed concrete beam type bridge, which solves the problems of long working period and more high-altitude operating processes of the conventional construction method. The method comprises the following steps of: performing an assembly process of a No. 0 section bracket system and a template system at the bridge position and a manufacturing process of a steel bar framework in parallel, wherein the manufacturing process of the steel bar framework is finished on the ground; after the No. 0 section bracket system at the bridge position and a bottom die are assembled, transporting the formed steel bar framework to the bridge position, and placing the steel bar framework on the bottom die through a lifting device; assembling a side die, an inner die and an end die; pouring and curing concrete; and releasing the dies. The method has the advantages of short operating time, high professionalized degree and high labor efficiency.

Description

technical field [0001] The invention belongs to the technical field of construction of prestressed concrete continuous beams and continuous rigid frame bridges in bridge engineering, and in particular relates to a rapid construction method for No. 0 section of a prestressed concrete beam type bridge. Background technique [0002] For the prestressed concrete continuous beam and the No. 0 section of the continuous rigid frame bridge, the bridge position is currently cast in place. The specific method is: set up a bracket or a bracket at the bridge position → install a formwork system → bind steel bars and install prestressed pipes in the formwork of the bracket or bracket → perform concrete pouring and maintenance. The disadvantages of this method are: there is only one working face, each process must be constructed in sequence, and the total construction period is long; all work at high altitudes makes it difficult to control the construction quality. Therefore, it is neces...

Problems solved by technology

[0003] In order to solve the problems of long construction period and many high-altitude operations during the construction of the No. 0 section of the prestressed concrete beam bridge, the present invention provides a rapid construction method for the No. 0 section of the prestressed concrete beam bridge, which changes the conventional sequential operation method into parallel operation. It provides the technological process of the entire construction process, such as the binding of the steel skeleton, hoisting in place, and concrete pouring.
