Quick laying method for prefabricated reinforced concrete integral crossing slab
The invention discloses a method for quickly laying a prefabricated reinforced concrete integral crossing plate, which relates to the field of crossing construction and comprises the following steps of: 1, transporting the prefabricated integral crossing plate to a constructed crossing; secondly, a ballast bed foundation pit is excavated, the bottom of the ballast bed foundation pit is trimmed, and a bottom cushion layer is laid with water slag and tamped; 3, measuring and controlling the depth of the foundation pit; fourthly, the prefabricated integral crossing plate is hoisted into the ballast bed foundation pit, and the levelness and the center line are regulated and controlled; 5, mounting a connecting steel rail; sixthly, a locomotive is used for pressure testing, the horizontal plane of the crossing plate is measured, and if inclination occurs, the crossing plate needs to be hoisted to reprocess the bottom cushion layer; seventhly, gaps in the two sides of the crossing plate are filled with C35 concrete; and 8, opening the road 14 days after opening the crossing railway. The problems that an existing steel mill railway crossing is long in construction period, low in crossing strength, prone to causing pavement damage and deformation when bearing heavy-load external force impact, not easy to repair after being damaged, high in maintenance cost, capable of affecting stable operation of railway tracks and the like can be solved.
本发明公开一种预制钢筋混凝土整体道口板快速铺设方法，涉及道口施工领域，步骤是：一、将预制整体道口板运至施工的道口；二、开挖道床基坑，修整道床基坑底部，用水渣铺设底部垫层并夯实；三、测量控制基坑深度；四、将预制整体道口板吊至道床基坑内，调控水平及中心线；五、安装连接钢轨；六、用火车头进行试压，测量道口板的水平面，如出现倾斜需将道口板吊起重新处理底部垫层；七、用C35混凝土填补道口板两侧缝隙；八、开通道口铁路14天后开通公路。本发明能解决现有钢厂铁路道口施工周期长，道口强度低、承受重载外力冲击易造成铺面破坏变形，且受损后不容易修补，维修费用高，影响铁路轨道的稳定运行等问题。
