Method for erecting precast beams in limited space
The invention relates to the technical field of road and bridge construction, and provides a method for erecting a precast beam in a limited space, which comprises the following steps of: dismantling a transverse moving device at a front supporting leg of a bridge erecting machine, a lower-layer wheel box and a transverse moving rail at a middle supporting leg, and changing a rear supporting leg of the bridge erecting machine into a hydraulic supporting device; transversely-moving rails are arranged on the bridge abutment and the cover beam in the transverse direction, a vertical jack is arranged on the side of each padstone, a transverse moving vehicle is arranged on the transverse-moving rails, a traction system of the transverse moving vehicle is fixed, and a front supporting leg of the bridge erecting machine is moved to the bridge abutment or the cover beam where the precast beam to be installed is located; the transverse moving vehicle is moved to the position below the bridge girder erection machine, the precast beam is conveyed to the position above a bridge abutment and a cover beam through the bridge girder erection machine, the precast beam is lowered to the transverse moving vehicle, the precast beam is transversely moved to the designed position along the transverse moving rail through the traction system, and the vertical jack is lifted to jack the precast beam and move the precast beam out of the transverse moving vehicle. And the vertical jack descends to place the precast beam on the padstone. According to the method, the precast beam can be constructed and installed in a narrow space.
本发明涉及道路桥梁施工技术领域，提供了一种有限空间内架设预制梁的方法，包括：拆除架桥机前支腿处的横移装置、中支腿处的下层轮箱和横移轨道，将架桥机的后支腿改为液压支撑装置；在桥台与盖梁上沿横向设置横移轨道，在每个垫石的侧方设置竖向千斤顶，在横移轨道上设置横移车，并固定横移车的牵引系统，将架桥机的前支腿移动至待安装预制梁所在的桥台或盖梁上；将横移车移动至架桥机的下方，将预制梁通过架桥机输送至桥台和盖梁的上方，下放预制梁至横移车上，通过牵引系统将预制梁沿横移轨道横移至设计位置处，升起竖向千斤顶将预制梁顶起，移出横移车，下降竖向千斤顶将预制梁放置在垫石上。该方法可以在较为狭窄的空间内施工安装预制梁。
