Overall dismantling construction process for large-span truss concrete bridge
The invention discloses an overall dismantling construction process for a large-span truss concrete bridge, which comprises the following construction steps of: 1, breaking and removing a guardrail, a hinge joint, a bridge deck system and the like, breaking and removing the bridge deck system and an accessory structure of a concrete continuous bridge according to holes from a main span truss area to two sides, after one hole is broken, carrying out next hole breaking construction, and breaking and removing a bridge deck pavement layer by using a crusher. The process has the beneficial effects that accurate calculation is carried out according to parameters of all components of the concrete bridge in the dismantling process so as to select corresponding hoisting and transferring equipment, the dismantling cost of the bridge can be greatly reduced on the premise of meeting normal dismantling of all the components of the bridge, and meanwhile in the dismantling process, a net bag and the navigation sealing measure are adopted according to actual dismantling requirements, damage to passing personnel in the bridge construction process is avoided, the safety of the bridge dismantling process is greatly improved, and the overall dismantling construction process is worthy of large-scale application and popularization.
本发明公开了一种大跨度桁架混凝土桥梁整体拆除施工工艺，它包括以下施工步骤：步骤1：护栏、铰缝、桥面系等的破除，砼连续梁桥桥面系及附属结构破除按孔进行，由主跨桁架区向两侧进行，一孔破除完成后进行下一孔破除施工，先用破碎机将桥面铺装层破除。有益效果在于：本发明通过在拆除过程中根据混凝土桥梁各部构件参数来进行精准计算，以选用相应的吊装转运设备，能够在满足桥梁各部分构件正常拆除的前提下，大大降低桥梁的拆除成本，同时在拆除过程中，根据实际拆除需要采用网兜以及封航措施，来避免桥梁施工过程中对来往人员造成损伤，大大提高了桥梁拆除过程的安全性，值得大规模推广应用。
