Installation method for cantilever pouring bridge fabrication machine
The invention provides a cantilever pouring bridge fabrication machine installation method. The cantilever pouring bridge fabrication machine installation method comprises the following construction steps that a 0 # block middle formwork is dismantled; setting out the track position of the bridge fabrication machine on the 0 # box girder, mounting L-shaped three-truss assembly platform supports with inclined struts at three webs of the box girder, and connecting profile steel at the tops of the supports into a whole; sleeper beam profile steel is installed; a front support and a roller carrier are installed, and main beam assembling cushion blocks are installed in sequence; the main beams are assembled into a whole on the ground site; outer mold longitudinal beam hanging belts and profile steel longitudinal beams are sequentially installed, a 0 # block bottom mold is dismantled, and middle cross beam hanging legs are installed; mounting a bottom die; installing a standard program to carry out a bearing test; lifting the longitudinal beam to place the inner mold in place; and installing a safety system. According to the method, conventional installation steps are innovated, line production is changed into parallel operation, independent component hoisting is changed into modular hoisting, for example, in the installation process of an assembly platform, modular assembly of four sections of a main beam is carried out at the same time, and the installation efficiency is greatly improved.
本发明提供一种悬臂灌注造桥机安装方法，包括如下施工步骤：拆除0#块中间模板；0#块箱梁放样出造桥机轨道位置，于箱梁三个腹板处安装带斜撑的“L”型三榀安拼平台支撑，支撑顶部型钢连接成整体；枕梁型钢安装；安装前支座、滚轮架，依次安装主梁拼装垫块；在地面场地将主梁拼装成整体；依次安装外模纵梁吊带、型钢纵梁，拆除0#块底模，安装中横梁挂腿；安装底模；安装标准程序进行承载试验；提升纵梁将内模就位；安装安全系统。本发明对常规安装步骤进行了创新，由流水作业改为平行作业，由独立构件吊装改为模块化吊装，如在拼装平台的安装过程中，同时进行主梁4个节段的模块化组装，大大提高了安装效率。
