the first step is as follows: preparing operation, namely placing a new ballast dump truck, a material transport vehicle and a stone ballast hopper truck on the same railway line, wherein the new ballast dump truck and the material transport vehicle are connected and then positioned at one end of the line, the stone ballast hopper truck is positioned at the other end of the line, and the distance between the new ballast dump truck and the stone ballast hopper truck is the sum of the length of a channel for storing new stone ballasts and the length of a safety distance of 20 meters;
the second step is that: the method comprises the following steps of (1) towing a new ballast dump truck by using a material transport truck or other vehicles, digging ditches at two sides of a railway line by using the new ballast dump truck (the length and the depth of the ditches are determined according to the length of a station line and the transfer and storage amount of the new ballast), conveying dug old ballasts to the material transport truck, and finally conveying the old ballasts to a specified place by using the material transport truck;
the third step: returning the material transport vehicle and the new ballast dump vehicle, moving the stone ballast hopper vehicle to the new trench dug in the second step, opening a ballast unloading port of the stone ballast hopper vehicle needing ballast unloading, and unloading the new stone ballast into the trench dug in the second step until the trenches on two sides of the line are fully unloaded;
the fourth step: the stone ballast hopper car returns, a new ballast dump car is pulled by the material transport car, and new stone ballasts which are unloaded in two side ditches of the railway line in the third step are dug by the new ballast dump working device and are conveyed to the material transport car through the conveying belt;
the fifth step: repeating the third step and the fourth step until all the required material transport vehicles are filled,
after the material transport vehicle is completely filled, repeating the third step, and unloading new stone ballasts in the stone ballast hopper vehicle into the trench excavated in the fourth step;
and a sixth step: and d, raking the new stone ballast discharged in the ditch in the fifth step by using a ballast raking and shaping mechanism to finish dumping work of the new stone ballast.
