Bridge composite beam erecting and hoisting construction method

Abstract

The invention provides a hoisting construction method for erecting a bridge composite beam, and belongs to the field of machinery. The method comprises the following steps: 1, preparing a site, splicing a bridge girder erection machine at a bridgehead roadbed, flattening and compacting the roadbed, and meeting the mounting load standard of the bridge girder erection machine; the bridge roadbed is generally composed of a roadbed, a road surface, a bridge, tunnel engineering, traffic engineering facilities and the like, and the construction method has the beneficial effects that the strength of the roadbed is guaranteed by adopting the strong cement reinforced concrete aggregates, so that in the process of erecting the bridge, when the bridge is erected subsequently, the construction period is shortened, and the construction efficiency is improved. The pavement structure can be further erected and supported conveniently, and a bridge roadbed treatment mode is adopted, so that the pavement of the lower bridge foundation support aspect structure is ensured.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a construction method for erecting and hoisting composite beams of bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; [0003] The substructure includes abutment, pier and foundation; the support is the force transmission device set at the support of the bridge span structure and pier or abutment; the auxiliary structure refers to th...
