Construction method for arched girder consolidation section of rigid connection curved beam space arch bridge
The invention discloses a construction method for an arched girder consolidation section of a rigid connection curved beam space arch bridge, which comprises the steps of 1) inserting and driving steel pipe piles under a riverbed to form a support, and arranging a distributive girder, a three-way regulator and a cushion block on the support; (2) determining the gravity center position of the arched girder consolidation section; (3) transporting the arched girder consolidation section to a construction site, and then carrying out positioning; (4) placing the arched girder consolidation section on cushion blocks along the positions of limiting marks and alignment marks; (5) measuring position parameters of the arched girder consolidation section by using a measuring instrument and a reflecting mirror, comparing the position parameters with theoretical values, calculating an adjusting difference value, and adjusting the arched girder consolidation section by using a three-way adjuster; and 6) welding the joint. Position parameters are measured through an instrument and a reflector, the gravity center position is calculated according to the section shape and the curve shape of the arched girder consolidation section, the effects that the arched girder consolidation section is stably lifted, the posture conforms to the installation line shape are achieved, and the effects that the positioning and adjusting precision is high, the adjustment is easy and easy to operate, and the installation period is shortened are achieved.
本发明公开了一种刚性连接曲梁空间拱桥的拱梁固结段的施工方法，1)在河床下插打钢管桩形成支架，在支架上布设分配梁、三向调节器以及垫块；2)确定拱梁固结段的重心位置；3)运输拱梁固结段至施工现场后定位；4)将拱梁固结段沿限位标记和对位标记的位置放至垫块上；5)使用测量仪和反射镜测量拱梁固结段的位置参数与理论值对比并求出调节差值，使用三向调节器对拱梁固结段调节；6)对接头处进行焊接。通过仪器和反射镜测量位置参数，根据拱梁固结段的截面形状和曲线线形计算重心位置，实现了拱梁固结段平稳起吊和姿态符合安装线形的效果，实现了定位和调节的精度高，调节简单易操作，缩短了安装工期的效果。
