Construction method for inclined beam lifting
The invention relates to a construction method for inclined beam lifting. The construction method comprises the steps that bent caps of two adjacent to-be-erected bridge prefabricated parts are determined, the distance between the bridge prefabricated parts longitudinally spanning the two bent caps is planned, after the working range of beam lifting equipment is determined, the bridge prefabricated parts are conveyed in place, the beam lifting equipment is in butt joint with the corresponding ends of the bridge prefabricated parts, and the beam lifting equipment works; and combined lifting including inclined lifting is carried out on the bridge prefabricated part, alignment operation, beam falling and pre-fastening treatment are carried out after the bridge prefabricated part is lifted in place till construction is completed, and shutdown is carried out. By the adoption of the combined lifting method of obliquely lifting the prefabricated bridge, the prefabricated bridge can be directly lifted and aligned from the position below the bridge floor, then the ground below the bridge floor is fully used as a conveying channel, the space on the two sides of the bridge floor does not need to be excessively borrowed or called, the labor cost and capital consumption are greatly reduced, the erection risk is reduced, and the construction efficiency is improved. The bridge prefabricated part is erected smoothly and compliantly, and the overall construction time is greatly shortened.
本发明涉及一种倾斜起梁的施工方法，确定相邻的两个待架设桥梁预制件的盖梁，规划纵跨于两个盖梁上的桥梁预制件间的间距，确认起梁设备工作范围后，桥梁预制件输送到位，起梁设备对接桥梁预制件的对应端，起梁设备工作，桥梁预制件进行包括倾斜抬升的组合式抬升，抬升到位后进行对准操作、落梁、预紧固处理，直至施工完毕，停机。本发明通过采用包括了倾斜抬升预制桥梁的组合式抬升法，预制桥梁可以从桥面下直接上提并对准，进而充分利用桥面下的地面作为输送通道，不需要过度借用或调用桥面两侧的空间，大幅降低人工成本、资金消耗，减少架设风险，桥梁预制件架设顺利、合规，整体施工时间大幅缩短。
