Highway bridge segmented dismounting method
The invention provides a highway bridge segmented dismounting method. The highway bridge segmented dismounting method comprises the following steps: S1, two SPMT vehicles are symmetrically arranged; S2, truss stand columns are arranged on the two SPMT vehicles respectively; S3, a cross beam is arranged at the upper ends of the truss stand columns; S4, two carrying pole beams are arranged at the upper end of the cross beam and fixed, and hydraulic lifting devices are arranged on the carrying pole beams; S5, the supporting beam set is arranged at the lower end of the highway bridge to be disassembled and connected with the corresponding hydraulic lifting device through a steel cable; S6, the hydraulic lifting device is controlled to lift, so that a steel cable of the hydraulic lifting deviceis in a stressed state; S7, the highway bridge to be disassembled is cut; S8, the hydraulic lifting device is continuously controlled after cutting; S9, the SPMT vehicle is controlled to arrive at apreset site; and S10, the supporting beam set and the steel cables are separated, the supporting beam set is pulled out, and the steel cable is lifted. According to the highway bridge segmented dismounting method, the cutting frequency is reduced, the construction time is shortened, and the dismounting material rate is increased.
本发明提供了一种公路桥梁分段拆卸方法，包括以下步骤：步骤S1：对称布置两台SPMT车；步骤S2：在两台SPMT车上分别布置桁架立柱；步骤S3：桁架立柱上端布置横梁；步骤S4：在横梁上端布置两个扁担梁并固定，扁担梁上设有液压提升装置；步骤S5：将支撑梁组置于待拆卸公路桥梁下端并通过钢索与对应的液压提升装置连接在一起；步骤S6：控制液压提升装置提升使其钢索达到受力状态；步骤S7：对待拆卸公路桥梁进行切割；步骤S8：切割后继续控制液压提升装置；步骤S9：控制SPMT车到预设场地；步骤S10：将支撑梁组与钢索分离抽出支撑梁组升起钢索。该公路桥梁分段拆卸方法减少切割次数，缩短了施工时间，提高了拆卸料率。
