Urban rail transit prefabricated plate type steel fiber concrete monolithic track bed construction method
The invention discloses a construction method of a prefabricated plate type steel fiber concrete monolithic track bed for urban rail transit. The construction method comprises the steps that S101, construction preparation is conducted; s102, initial adjustment of the prefabricated track plate is conducted, specifically, the prefabricated track plate is subjected to initial adjustment through the threaded lead screw till the top face of the prefabricated track plate is in a horizontal state; s103, a ditch formwork is installed; s104, reinforcing and pressing the prefabricated track plate; s105, erecting and fine adjustment of the prefabricated track plate are conducted, specifically, the center position of the prefabricated track plate is adjusted through inclined supports on the two sides till the center line of the prefabricated track plate coincides with the center line of the base, and the elevation position of the prefabricated track plate is adjusted through a threaded lead screw till the design requirement is met; and S106, steel fiber concrete is poured. The integrated track bed has the beneficial effects that the integrated track bed formed through one-time pouring is achieved, the laying quality of the track bed is improved, the alignment installation procedure is carried out before pouring, the construction procedure is greatly simplified, the track construction efficiency is improved, and the construction period is shortened.
本发明公开了一种城市轨道交通预制板式钢纤维混凝土整体道床施工方法，包括S101、施工准备；S102、预制轨道板初调：通过所述螺纹丝杠对所述预制轨道板进行初调直至所述预制轨道板的顶面处于水平状态；S103、水沟模板的安装；S104、预制轨道板加固压紧；S105、预制轨道板架设精调：通过两侧斜支撑调节预制轨道板的中心位置直至所述预制轨道板的中线与基底的中线重合，螺纹丝杠调节所述预制轨道板的高程位置直至达到设计要求；S106、浇筑钢纤维混凝土。本发明的有益效果为：实现了一次浇筑成型的整体式道床，提高了道床铺设质量，在浇筑前进行找正安装工序，极大简化了施工工序，提高了轨道施工效率，缩短了施工周期。
