Overpass bridge construction method
The invention discloses an overpass bridge building method, which belongs to the field of bridge building, and comprises the following steps: building cast-in-place piles of a left width splicing section and a right width splicing section; only the main line right part is conducted, a cast-in-place pile of the main line left part is built, meanwhile, construction of a cover beam and a bridge abutment is conducted, then a beam plate is erected, and a bridge deck structure layer is laid; only the left width splicing width section is conducted, a main line right width cast-in-place pile is built, meanwhile, construction of a capping beam and a bridge abutment is conducted on the main line left width, after construction of the right width cast-in-place pile is completed, construction of the capping beam and the bridge abutment of the main line right width and the right width splicing width section is conducted, beam plates are erected, and a bridge deck structure layer is laid; only the main line right width and the right width splicing section are conducted, a beam plate of the left width splicing section is dismantled, the left width splicing section is connected with a beam plate of the main line left width, and a pavement structure layer is paved; and a ramp roadbed is tunneled at the bottom. The problems that when an overpass bridge is built on an existing road, the traffic control time is long, the influence on vehicle passing is large, and economic losses are large can be solved.
本发明公开了一种跨线桥修建方法，属于桥梁修建领域，其包括以下步骤：修建左幅拼宽段和右幅拼宽段的灌注桩；只导通主线右幅，修建主线左幅的灌注桩，同时进行盖梁和桥台的施工，然后架设梁板，铺筑桥面结构层；只导通左幅拼宽段，修建主线右幅灌注桩，同时对主线左幅进行盖梁和桥台的施工，待右幅灌注桩施工完后，对主线右幅和右幅拼宽段的盖梁和桥台的施工，架设梁板，铺筑桥面结构层；只导通主线右幅和右幅拼宽段，拆除左幅拼宽段梁板，将左幅拼宽段与主线左幅的梁板连接，并铺筑路面结构层；全部导通，在底部掘进匝道路基。本发明可以解决在既有公路上修建跨线桥时，交通管制时间长，对车辆通行影响较大，经济损失大的问题。
