Large-span section assembling bridge manufacturing machine and assembling construction process thereof

Abstract

The invention discloses a large-span section assembling bridge manufacturing machine and an assembling construction process thereof. The bridge manufacturing machine comprises a bridge manufacturing machine main body structure, a crown block system and a forward moving system, wherein the bridge manufacturing machine main body structure comprises a left main truss, a right main truss, an upper lateral brace and a lower lateral brace; the two main trusses comprise a main beam and a guide beam, and the guide beam has a three-layer step type truss structure; and a plurality of connecting rods comprise 87 type military beams and heterogenic rods. The assembling construction process comprises the following steps of: 1. assembling and constructing a first hole beam of a single-hole beam or a porous beam; forwards shifting the bridge manufacturing machine main body structure to construct the next hole beam across the hole; and repeatedly constructing till the integral construction of a constructed bridge is finished and the bridge manufacturing machine main body structure is disassembled. The bridge manufacturing machine has reasonable structural design, large span, convenient processing, manufacture, assembly and installation, strong weight capacity and low investment cost; and the used assembling construction process is simple, is convenient for realization and can be effectively suitable for the assembling construction process of bridge sections with the span of 64m and below 64m.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a large-span segmental assembled bridge building machine and an assembled construction process thereof. Background technique [0002] The pier of the Xishan Temple Super Bridge is a thin-walled hollow pier with a pier height of 49.5-56 meters; the superstructure is designed as a 10-span 64-meter section assembled box girder with a beam length of 66.2 meters, a beam height of 4.9 meters, and a beam top width of 5.3 meters. It weighs about 1300 tons, so the construction is more difficult. Nowadays, the spans of the conventional assembled bridge building machines used are all below 56 meters, so they cannot meet the construction needs of the main 64-meter girder span of the Xishansi Bridge. The structure of the bridge crane is improved, and a segmental assembly bridge building machine is designed to meet the construction needs of the bridge span, the assembl...

AI Technical Summary

Problems solved by technology

Nowadays, the spans of the conventional assembled bridge building machines used are all below 56 meters, so they cannot meet the construction needs of the main 64-meter girder span of the Xishansi Bridge. The structure of the bridge machine is improved, and a segmental assembly bridge building machine is designed to meet the construction requirements, the assembly construction process is simple, and the construction effect is good.
