Quick laying method for prefabricated integral crossing plate
The invention discloses a method for quickly laying a prefabricated integral crossing plate, which relates to the field of railway crossing construction, and comprises the following steps of: excavating a foundation pit, filling a foundation layer, laying a panel, and laying steel rails and line sequential connection sections at two ends of a crossing; a prefabricated crossing plate adopted in the rapid laying process is a prefabricated concrete plate, a dovetail type rail bearing groove is formed in the top end in the prefabricated crossing plate, and connecting steel plates are arranged at the ends of the two side faces of the prefabricated crossing plate. The concrete transition sections are arranged on the two sides of the prefabricated crossing plate and are flush with the prefabricated crossing plate in height. A water granulated slag cushion layer is arranged below the prefabricated crossing plate and the concrete transition section, and a concrete foundation layer formed by dry mixing of melon-grain stone is arranged below the water granulated slag cushion layer. The problems that an existing railway crossing is long in construction period, low in crossing strength, incapable of bearing impact and rolling of heavy-load automobiles, often prone to pavement damage and deformation and not easy to repair after being damaged; and the problems of short maintenance period, high maintenance cost, influence on the stability of the railway track and large potential safety hazard are solved.
本发明公开了一种预制整体道口板快速铺设方法，涉及铁道道口施工领域，其步骤是：基坑开挖—填充基础层—铺设面板—铺设钢轨和道口两端线路顺接段；快速铺设中采用的预制道口板为预制混凝板，预制道口板内部顶端燕尾式承轨槽，预制道口板两侧面端部设置有连接钢板；混凝土过渡段设在预制道口板的两侧，高度与预制道口板平齐；预制道口板和混凝土过渡段下面为水渣垫层，水渣垫层下面为用瓜米石干拌的混凝土基础层。本发明可以解决现有的铁路道口施工周期长，道口强度低、不能承受重载汽车的冲击辗轧，经常造成铺面破坏变形，且受损后不容易修补；维修周期短、维修费用高，影响铁路轨道的稳定，存在较大的安全隐患的问题。
