Maintenance method of ballast track bed
The application relates to a maintenance method of a ballast track bed. A railway ballast cementing layer is arranged on the surface layer of a ballast track bed; and the railway ballast cementing layer is obtained by cementing granular railway ballasts laid on the surface layer of the ballast track bed. The maintenance method comprises the following steps: cleaning dust on the railway ballast cementing layer; destroying the structure of the cleaned railway ballast cementing layer, and tampering a ballast track bed; re-paving the granular railway ballast on the surface layer of the tamped ballast track bed; and cementing the relaid granular railway ballast to obtain a new railway ballast cementing layer. Therefore, a local ballast track bed can be maintained, construction is conducted on an operation line through skylight time, and normal operation of a train is not affected; maintenance related tools and materials are simple, maintenance is convenient, and cost is low. Meanwhile, therailway ballast cementing layer can effectively prevent pulverized coal from invading the ballast bed, a problem that the ballast bed is hardened due to pulverized coal invasion is solved, and a largeamount of screening cost is saved; in addition, the ballast bed with the surface layer sealed through cementation still has a good drainage function.
本申请涉及一种有砟道床的维修方法。其中，有砟道床的表层设有道砟胶结层；道砟胶结层为铺设在有砟道床的表层的颗粒道砟经胶结得到。维修方法包括：清理道砟胶结层上的粉尘；破坏清理后的道砟胶结层的结构，捣固有砟道床；在捣固后的有砟道床的表层重新铺设颗粒道砟；对重新铺设的颗粒道砟进行胶结，得到新的道砟胶结层。基于此，可对局部的有砟道床进行维修，利用天窗时间在运营线进行施工，不影响列车正常运营；维修涉及的工具和材料简单，养护维修方便，成本低。同时，道砟胶结层能够有效阻止煤粉侵入道床，解决由煤粉侵入导致的有砟道床板结问题，节约了大量清筛成本；并且，表层通过胶结封闭后的道床仍具有良好的排水功能。
