Adjustable frame plate ballastless track bed construction method
The invention relates to a construction method of an adjustable frame plate ballastless track bed. The construction method comprises an assembling curve track panel construction technology, a tool rail replacing traditional fixed-length steel rail assembling track panel technology, a sawtooth movable type base plate geometric dimension adjusting technology and a clamping groove type stacking height adjusting technology. The track lining process which is purely manually carried out in a tunnel in the prior art is adjusted into synchronous operation of assembling curved panels and assembling track panels on a track panel base, a large amount of labor cost is saved, track panel precision control is improved, operation time is shortened, the phenomenon of frequent occurrence of track hoisting safety accidents is effectively avoided, and the core is to reduce the self weight of the track panels and improve the hoisting efficiency of the track panels. According to the technology for adjusting the geometric dimension through the sawtooth movable type base plate and the technology for overlaying and heightening the clamping groove type reinforced concrete, on the basis that a track gauge block is replaced to adjust the track gauge and a heightening base plate and a thickened iron base plate are adopted to adjust the height in the prior art, through innovation and improvement, the track gauge adjusting and height adjusting range is widened, and the repairability of a line is improved; and convenience and guarantee are provided for safe operation and maintenance of the subway.
本发明涉及一种可调式框架板无砟道床施工方法，组装曲线轨排施工技术，工具轨替代传统定尺钢轨组装轨排技术，锯齿移动式垫板调整几何尺寸技术，卡槽式叠加调高技术。将传统由纯人工在隧道内进行拨道工序调整为在轨排基地进行组装曲排与拼装轨排同步作业，节约了大量人工成本、提升了轨排精度控制，缩短了作业时间，有效避免了轨道吊装安全事故频发现象，其核心为降低轨排自重，项目提出的锯齿移动式垫板调整几何尺寸技术及卡槽式钢筋混凝土叠加调高技术，在传统采用更换轨距块调整轨距、采用调高垫板及加厚铁垫板调整高低的基础上，通过创新改进，提升了轨距调整、高低调整范围，增大了线路的可修复性，为地铁安全运维提供便利、提供保障。
