Tunnel boot sleeving method replaceable supporting block ballastless track construction method
The invention discloses a tunnel boot sleeving method replaceable supporting block ballastless track construction method. The main construction process comprises the steps of pre-burying reinforcing steel bars in a base, roughening or chiseling the base, implanting connecting reinforcing steel bars, erecting a ballast bed lower-layer reinforcing mesh, assembling a track panel on site, erecting thetrack panel and roughly adjusting in place, erecting upper-layer longitudinal and transverse reinforcing steel bars, erecting a ballast bed template, finely adjusting and fixing the track panel, pouring ballast bed concrete and plastering, loosening fasteners after initial setting, curing concrete, dismounting and transferring the template. By means of the method, the technical problem in the prior art that a supporting block is difficult to replace is solved, and the replaceable supporting block is constructed through a boot sleeving method.
隧道套靴法可换式支承块无砟轨道施工方法，主要施工流程为：基底预埋钢筋‑‑基底拉毛或凿毛‑‑植入连接钢筋‑‑架设道床下层钢筋网‑‑现场组装轨排‑‑架设轨排并粗调到位‑‑架设上层纵横向钢筋‑‑架立道床模板‑‑精调并固定轨排‑‑浇筑道床混凝土并抹面‑‑初凝后松开扣件‑‑混凝土养护‑‑拆除、倒运模板。本发明通过上述方法，解决了现有技术中存在的支承块更换困难的技术问题，提供了一种可更换式支撑块采用套靴法施工。
