Construction technology of urban railway ballastless track
The invention relates to the technical field of railway ballastless track construction, in particular to a construction technology of a city railway ballastless track. The construction method comprises the following steps of: 1, constructing a common damping ballast bed: surveying and lofting, chiseling foundation concrete, cleaning, mounting lower-layer reinforcing steel bars and expansion joints of a ballast bed plate, placing a track panel in place, coarsely adjusting, mounting a support frame, coarsely adjusting and positioning the track panel, mounting upper-layer reinforcing steel bars of the ballast bed plate, welding stray current net reinforcing steel bars, mounting a template, finely adjusting and fixing the track panel, pouring ballast bed concrete, plastering and tamping; and track bed concrete is maintained and cleaned, supports and formworks are dismantled, track bent frames are dismantled, and curve superelevation is carried out. Construction under different track bed conditions can be achieved, and the method has the advantages of being easy and convenient to operate, safe, practical, accurate in track geometric dimension, rapid in positioning and the like.
本发明涉及铁路无砟轨道施工技术领域，具体为一种市域铁路无砟轨道的施工工艺。一、一般减震道床施工：测量放样、基础混凝土凿毛、清洗、道床板下层钢筋和伸缩缝安装、轨排就位、粗调、安装支撑架、轨排粗调定位、安装道床板上层钢筋及杂散电流网钢筋焊接、安装模板、精调并固定轨排、道床混凝土浇筑、抹面和捣固、道床混凝土的养生和清理、拆除支撑及模板、拆除轨道排架、曲线超高设置。本发明可实现不同道床条件的施工，具有操作简便、安全实用和轨道几何尺寸精确、快速定位等特点。
