Construction method of railway steel pylon crossing multi-track operation line
The invention belongs to the technical field of bridge engineering construction, and particularly relates to a construction method of a railway steel pylon crossing a multi-track operation line. The method comprises the following steps: S100, support erecting: firstly, installing a construction foundation according to design requirements, and after foundation construction is completed, erecting a plurality of steel pylon assembly supports on the foundation; S200, horizontal rotation structure installation: embedding a bearing platform steel box into a lower bearing platform, sequentially installing a horizontal rotation spherical hinge and a pylon bottom section on the bearing platform steel box, arranging a vertical rotation spherical hinge on the upper portion of the pylon bottom section, and arranging a rotary disc steel box on the periphery of the pylon bottom section; S300, pylon horizontal splicing: sequentially splicing pylons by taking the pylon bottom section as a starting point, and welding and connecting the pylons into a whole; S400, installation of a vertical rotating system; S500, vertical rotation construction; S600, horizontal swivel construction: winding a steel strand on the turntable steel box, and pulling the steel strand to horizontally swivel the pylons to a designed position; and S700, closure: temporarily locking the two ends of the pylons through steel plates, and performing pylon closure construction through skylight points.
本发明属于桥梁工程施工的技术领域，具体是一种跨越多股道运营线的铁路钢索塔施工方法。包括以下步骤，S100～支架搭设，首先安装设计要求施工基础，基础施工完成后，在基础上搭设若干组钢索塔拼装支架；S200～安装水平转体结构，将承台钢箱埋入下承台，在承台钢箱上依次安装水平转体球铰和索塔底部节段，索塔底部节段上部带有竖转球铰，索塔底部节段周边设置转盘钢箱；S300～索塔卧拼，以索塔底部节段为起点，依次拼装索塔，并焊接连接成整体；S400～竖转系统的安装；S500～竖转施工；S600～水平转体施工，在转盘钢箱上缠绕钢绞线，牵引钢铰线将索塔水平转体至设计位置；S700～进行合拢，利用钢板临时锁定索塔两端，利用天窗点进行索塔合龙施工。
