Pile type steel structure bridge roadbed pavement and construction method thereof
The invention relates to the technical field of bridge construction, in particular to a pile type steel structure bridge roadbed pavement and a construction method thereof, and the pile type steel structure bridge roadbed pavement comprises a pile type pier, a bridge box body and a bridge floor cushion frame; after the steel structure bridge runs for a long time, deformation between structural parts of the steel structure bridge can be transmitted to the expansion joint to be buffered, and the influence on the stress change of a bridge deck is caused when the vehicle passes by, so that a thicker roadbed layer needs to be laid on the steel structure bridge to balance the stress effect on the bridge structure, the dead weight of the bridge structure is increased, and the construction time of the bridge structure is prolonged; therefore, through the cushion plate and the steel wire mesh arranged in the bridge floor cushion frame, the load performance of the roadbed is improved through the wave-shaped cushion plate, sand laid in the roadbed material is in contact with the surface of the bridge box body, the force transmission effect of the roadbed on the bridge box body is enhanced, and the dead weight of the bridge is reduced under the condition that the road operation requirement is met, therefore, the applicability of pile type steel structure bridge roadbed pavement construction is improved.
本发明涉及桥梁施工技术领域，具体涉及一种桩柱式钢结构桥梁路基路面及其施工方法，包括桩柱式桥墩、桥梁箱体和桥面垫框；由于钢结构桥梁在长时间的运行后，其结构件间的形变会传递到伸缩缝的部位进行缓冲，并在行车经过时对桥面应力变化的影响，需要在钢结构桥梁上铺设较厚的路基层来均衡对桥梁结构的应力效应，增加了桥梁结构的自重和施工时间；故此，本发明通过设置在桥面垫框中的垫板和钢丝网，通过波浪形垫板提升路基的负载性能，并使路基材料中铺设的砂子接触在桥梁箱体的表面，增强路基对桥梁箱体的力传递作用，在满足公路运行要求的情况下降低了桥梁的自重，从而提升了桩柱式钢结构桥梁路基路面施工的适用性。
