Mechanical replacement and laying construction method for ballast turnout
The invention relates to a mechanical replacement and laying construction method for a ballast turnout. The method comprises the steps of selecting a turnout pre-laying position, transporting the turnout, replacing and laying the turnout within blocking time, treating new and old stone ballasts, welding the turnout and the like. According to the method, the whole set of turnouts are pre-laid outside the blocking time, and the method is implemented within the blocking time as follows: the whole set of turnouts are transported to the vicinity of a turnout replacing and laying area by adopting turnout replacing and laying equipment, old turnouts are dismantled and moved away, ballast beds are excavated, old stone ballasts are removed and transferred, the ballast beds are leveled, new turnouts are laid, tamping and stabilizing are performed, the turnouts are finely adjusted, and finally turnout welding is completed until a line is opened. According to the invention, the turnout changing and paving quality is improved, the overall construction time is saved, the blocking construction frequency is reduced, the construction can be flexibly carried out according to the blocking time, the mechanization degree is improved, the construction safety risk and the labor intensity are reduced, meanwhile, the material and manpower consumption is reduced, and the cost is saved for the turnout changing and paving construction.
本发明涉及一种有砟道岔机械化换铺施工方法，包括道岔预铺位置的选取、道岔的运输、封锁时间内换铺道岔、新旧石砟的处理、道岔焊接等步骤。本发明在封锁时间外对整组道岔进行预铺，在封锁时间内实现：采用道岔换铺设备将整组道岔运输到道岔换铺区域附近，拆除和移走旧道岔，挖掘道床，清除和转运旧石砟，平整道床，铺设新道岔，捣固稳定，道岔精调，最后完成道岔焊接直至线路开通。本发明提高了道岔换铺质量，节约了整体施工时间，减少了封锁施工次数，可灵活根据封锁时间进行施工，提高了机械化程度，降低了施工安全风险和劳动强度，同时也减少了物资和人力消耗，为道岔换铺施工节省了成本。
