Road bridge girder erection machine tunnel portal installation method
The invention discloses a highway bridge girder erection machine tunnel portal installation method. The method comprises the steps that round girders of middle supporting legs are placed on the edge of a tunnel portal abutment; assembling a main beam on the roadbed at the other end of the tunnel and hoisting the main beam to a beam transporting vehicle; a riding wheel group of a middle supporting leg is mounted at the lower end of the main beam; conveying the main beam from the other end of the tunnel to a round girder of a middle supporting leg at a tunnel portal, and connecting a riding wheel group of the middle supporting leg with the round girder in a matching manner; a temporary support for supporting the rear end of the main beam is installed in the tunnel, and the main beam is unloaded from the beam transporting vehicle; temporary rear supporting legs for supporting the rear ends of the main beams are installed in the tunnel; a front supporting leg, a front auxiliary supporting leg, a front upper cross beam, a rear upper cross beam and a main beam connecting rod are sequentially installed through a crane, and a longitudinal moving truss vehicle and a crown block are installed on a main beam; installing a whole machine electrical system and a safety device; the middle supporting leg is retreated to the middle of the main beam, and a balance weight is hung at the rear end of the main beam; and the whole machine moves forwards, the main beam moves forwards to the bent cap, and hole passing is completed. According to the method, the construction sequence is optimized, the construction efficiency is improved, and the safety in the construction process is ensured.
本发明公开一种公路架桥机隧道口安装方法，包括在隧道口桥台边缘安放中支腿的元宝梁；在隧道另一端的路基上拼装主梁并吊运至运梁车；在主梁下端安装中支腿的托轮组；将主梁从隧道的另一端送至隧道口的中支腿的元宝梁上，将中支腿的托轮组和元宝梁配合连接；在隧道内安装支撑主梁后端的临时支撑，将主梁卸下运梁车；在隧道内安装支撑主梁后端的临时后支腿；使用吊车依次安装前支腿、前辅助支腿、前上横梁、后上横梁、主梁连接杆，主梁上安装纵移桁车和天车；安装整机电气系统和安全装置；将中支腿回退至主梁中部，在主梁后端悬挂配重；整机前移，将主梁前移至盖梁处，完成过孔。本发明优化了施工顺序，提高了施工效率，且确保施工过程中的安全。
