Directly-buried fastener and construction method thereof
The invention relates to the technical field of rail construction, and especially relates to a directly-buried fastener and a construction method thereof. The directly-buried fastener comprises a baseplate and supporting columns, the base plate comprises an upper plate body and a lower plate body, the size of the lower plate body is smaller than that of the upper plate body, the upper plate body,the lower plate body and the supporting columns are integrally connected, the bottom of the upper plate body is connected with the lower plate body, and the bottom of the lower plate body is connected with the two supporting columns arranged in an aligned mode. The size of the lower plate body is smaller than that of the upper plate body, quick-dry cement or an adhesive can be injected into a lower plate body mounting groove of a ballast bed, the two supporting columns can be respectively mounted in two supporting column mounting holes of the ballast bed, the lower plate body is mounted in alower plate body mounting groove of the ballast bed, at the moment, the bottom face of the upper plate body makes contact with the top face of the ballast bed, the lower plate body and the supportingcolumns play a role in positioning, and the upper plate body can be placed at the designated position of the ballast bed, so the installation error of the upper plate body is reduced, then the installation error of a steel rail on the upper portion of the upper plate body is reduced, and the installation precision of the steel rail is improved.
本发明涉及轨道施工的技术领域，尤其是一种直埋扣件及其施工方法，包括垫板和支柱，垫板包括上板体和下板体，下板体的尺寸小于上板体的尺寸，上板体、下板体和支柱为一体化连接，上板体底部连接有下板体，下板体底部连接有两对位设置的支柱。本发明的下板体的尺寸小于上板体的尺寸，可以通过往道床的下板体安装槽内注入速干水泥或胶黏剂，可将两支柱可分别安装于道床的两支柱安装孔内，下板体安装于道床的下板体安装槽内，此时的上板体底面与道床顶面接触，下板体和支柱起到了定位的作用，可以使上板体放置在道床的指定位置，减少了上板体的安装误差，进而减少了上板体上部的钢轨的安装误差，即增加了钢轨的安装精度。
