The invention relates to a combined bridge structure and a construction method. The combined bridge structure comprises a bearing structure, a cover beam structure, and a connection support structure,wherein the cover beam structure comprises a cover beam body and a dead-load body, the cover beam body comprises a pressed side and a tensioned side, the pressed side faces the bearing structure, thetensioned side is back to the bearing structure and forms a prestress structure, and the dead-load body is arranged on the surface of the tensioned side; and the connection support structure is arranged between the bearing structure and the cover beam structure, and comprises a movable support seat pre-arranged between the bearing structure and the cover beam structure, and used for supporting the cover beam body, and a fixed connection body filled among the movable support seat, the bearing structure and the cover beam structure in a manner of being lagged behind the arrangement for the dead-load body. According to the combined bridge structure and the construction method, the bending moment applied onto the bearing structure by the cover beam structure is low and the connection manner is high in structure stress, so that the bending of the bearing structure and cracks are avoided.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a combined bridge structure and a construction method. Background technique [0002] In the construction of cities or highway bridges, especially for urban viaducts with heavy traffic on the ground, the traditional construction method of pouring concrete on site is directly carried out on-site at the bridge site, which will block traffic for a long time and cause serious problems. Large construction pollution cannot meet the current requirements for ecological construction and environmental protection; and the repeated configuration of construction equipment and auxiliary facilities has caused problems such as large resource and energy consumption, and a lot of waste of financial and material resources. [0003] Different from the traditional cast-in-place construction method, most of the work is completed in the factory by adopting the "fabricated bridge construction method"...
