Multi-span continuous steel box girder pedestrian overpass dismantling system and construction method
The invention relates to a multi-span continuous steel box girder pedestrian overpass dismantling system and a construction method. Comprising a green belt area temporary support anchoring system, an asphalt concrete pavement area temporary support anchoring system, a hanging movable type cutting falling slag discharging safety protection system, a bench dismantling protection support, a dismantling segment steel box girder shelving dismantling support and a hoop pier column temporary cantilever supporting frame. The dismantling construction process of the multi-span continuous steel box girder pedestrian overpass on the existing operation road is innovated, and the construction efficiency of anchoring temporary supports on a green belt and an asphalt concrete pavement can be improved through a green belt area temporary support anchoring system and an asphalt concrete pavement area temporary support anchoring system; the anchoring effect is good; the hanging movable type cutting falling slag discharging safety protection system can prevent steel slag generated in the steel box girder cutting process from falling to an operation road, and the potential safety hazard of construction is reduced; the bench dismantling protection support can prevent the platform bridge bench from falling during dismantling, and the construction safety is improved.
本发明涉及一种多跨连续钢箱梁人行天桥拆除体系及施工方法，包括绿化带区域临时支架锚固体系、沥青混凝土路面区域临时支架锚固体系、吊挂移动式切割放落渣安全防护体系、梯段拆除防护支架、拆除节段钢箱梁搁置拆解支架以及抱箍墩柱临时悬挑支撑架。本发明对既有运营公路上多跨连续钢箱梁人行天桥拆除施工流程进行创新，绿化带区域临时支架锚固体系和沥青混凝土路面区域临时支架锚固体系可提高临时支架在绿化带及沥青混凝土路面上锚固的施工效率，且具有良好的锚固效果；吊挂移动式切割放落渣安全防护体系可防止钢箱梁切割过程中产生的钢渣掉落至运营道路，降低施工的安全隐患；梯段拆除防护支架可防止天桥梯段拆除时坠落，提高施工安全性。
