Overall positioning framework and method for improving positioning precision of prestressed corrugated pipe
The invention discloses an integral positioning framework and method for improving the positioning precision of a prestressed corrugated pipe. The integral positioning framework comprises a beam body bottom plate; the beam body web and the beam body bottom plate are integrally poured and formed; the bottom plate positioning net rack is arranged in the beam body bottom plate, and the bottom plate positioning net rack is provided with a plurality of bottom plate corrugated pipe hole sites which are arranged at intervals and used for positioning and installing bottom plate prestress corrugated pipes; the web positioning net rack is arranged in the beam body web, the web positioning net rack and the bottom plate positioning net rack are assembled and fixedly connected, and the web positioning net rack is provided with a plurality of web corrugated pipe hole sites which are arranged at intervals and used for positioning and installing web prestressed corrugated pipes. The problems that in the prior art, a single U-shaped rib or a #-shaped reinforcing steel bar is adopted for positioning the prestressed corrugated pipe, the prestressed corrugated pipe is installed firstly, then the positioning rib is welded and fixed, the prestressed corrugated pipe is disturbed in the welding and fixing operation, deviation is generated, and the prestressed corrugated pipe is damaged are solved. The service life and the structural durability of the railway bridge body are further influenced.
本发明公开了一种用于提高预应力波纹管定位精度的整体定位架构及方法，包括：梁体底板；梁体腹板，与梁体底板之间一体浇筑成型；底板定位网架，内置于梁体底板，且底板定位网架设有若干个间隔设置的底板波纹管孔位，用于定位安装底板预应力波纹管；腹板定位网架，内置于梁体腹板，腹板定位网架与底板定位网架之间装配固接相连，且腹板定位网架设有若干个间隔设置的腹板波纹管孔位，用于定位安装腹板预应力波纹管。解决了现有技术对于预应力波纹管的定位均是采用单个U型筋或井字型钢筋，且实施先安装预应力波纹管，而后进行定位筋焊接固定，导致在焊接固定作业时会扰动预应力波纹管产生偏差，进而影响铁路桥梁体的使用寿命及结构耐久性的问题。
