Prefabricated slab ballast bed construction method
The invention discloses a precast slab ballast bed construction method. The method comprises the steps that a precast slab is laid to the position where a slab is to be laid; the prefabricated slab at the position where the slab is to be laid is grabbed and positioned; a fixing tool of the prefabricated slab is installed, and the lower prefabricated slab is moved and positioned; concrete is filled below the prefabricated slab, and isolating layers isolated from the concrete are preset at the bottom and on the side faces of the prefabricated slab; the limiting boss and the slab joint are subjected to backfilling treatment; the fixing tool of the prefabricated slab is detached, and steel rails and buckle parts are installed; and PTN waterproof construction treatment is carried out. The whole construction process is few, the construction technology and flow are simple, the mechanization and intelligence degree is high, operation is convenient, line production organization is facilitated, the construction speed is high, the construction quality is good, and the actual construction requirement can be met.
本发明公开了一种预制板道床施工方法，包括：将预制板铺设至待铺板位置上；对所述待铺板位置处的预制板进行抓板定位；安装所述预制板的固定工装并移机调位下块预制板；在所述预制板下填充混凝土，其中，所述预制板底部及侧面预设有与混凝土相隔离的隔离层；对限位凸台及板缝进行回填处理；拆除所述预制板的固定工装并进行钢轨及扣配件安装；进行PTN防水施工处理。本发明整体施工工序少，施工工艺及流程简单，机械化及智能化程度高，操作方便，利于组织流水作业，施工速度快，施工质量佳，能满足实际施工需求。
