Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] Such as Figure 1-20 The bridge erecting machine of the embodiment includes a main truss 1, the main truss 1 is a truss structure arranged along the bridge direction, and the main truss 1 includes longitudinal beams arranged along the bridge direction and triangular trusses located on the lateral sides of the lower end of the longitudinal beams, two groups The triangular trusses are arranged at intervals along the transverse bridge, leaving gaps in the middle for the crane cables to pass through.

[0054] This embodiment is supported on the bridge deck that has been assembled by a plurality of fulcrums, including the front fulcrum located at the front half of the main truss 1 and the rear fulcrum of the rear half (the front of the present embodiment refers to Figure 11 in the right direction, the rear refers to Figure 11 In...

Abstract

The invention relates to the technical field of bridge construction, in particular to a prefabricated and assembled bridge integrated rapid construction method. The bridge erection machine is built onthe assembled bridge deck, the precast pier columns, prefabricated cover beams and steel main beams are transported by a beam transporting truck to the assembled deck, and the bridge erecting machinelifts the precast pier columns to the bearing platform poured on the ground; after the fixed connection between the precast pier column and the bearing cap is completed, the bridge erecting machine lifts the steel main girder to two adjacent precast cover beams along the bridge direction, then, the bridge deck is laid on the steel main girder to complete the assembly of the span section, and theprefabricated cover girder is lifted to the prefabricated pier column which is fixedly connected with the bearing cap, and the bridge erecting machine is driven to travel one span along the assembledbridge section to carry out the assembly of the next span section, and the assembly of all bridge sections is sequentially carried out until the assembly of all bridge sections is completed. The method can complete the installation of all components such as the precast pier column, the precast cover beam, the steel main beam and the like, realizes the simultaneous construction of the upper and lower structures of the bridge, and effectively improves the construction efficiency of the site.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an integrated rapid construction method of a prefabricated bridge. Background technique [0002] In the field of bridge construction, prefabricated bridges can effectively increase the speed of on-site construction, ensure the quality of structural components, improve structural durability, and have broad application scope and prospects. [0003] In the on-site construction of prefabricated bridges, bridge erecting machines are usually used to erect the upper structure, and crawler cranes are used to erect the substructure such as pier columns and cover beams. The construction process requires a lot of manual assistance, and the construction efficiency is low. Traffic has a big impact. The upper structure of the bridge and the lower piers usually need to be constructed twice, which seriously restricts the construction efficiency of the bridge, and the huge amount of ...
