Step S4: the operation vehicle lifts the welded turnout 7 through the rail lifting device 4 and moves to the laying position of the turnout 7. When the operating vehicle runs and encounters an obstacle in the process of running, the transport trolley 6 runs to the position below the operating vehicle and the turnout 7, the operating vehicle and the turnout 7 are placed on the transport trolley 6, the running device 2 is folded, and the transport trolley 6 transports the operating vehicle and the turnout 7 to pass through the obstacle.

When the operation vehicle unloads the turnout 7 through the rail lifting device 4, the turnout 7 is welded on a welding platform or a traveling rail. After the welding is completed, the working vehicle lifts the welded turnout 7 through the rail lifting device 4 and moves to the laying position of the turnout 7. When the operation vehicle encounters an obstacle in the traveling process, the traveling devices 2 support the operation vehicle to ascend to a certain height, and at the moment, the two transport trolleys 6 travel to the positions below the operation vehicle and the turnout 7 and are respectively positioned on the front side and the rear side of the two traveling devices 2. The height of the running gear 2 in the vertical direction is adjusted, so that the operation vehicle and the turnout 7 are placed on the transport trolley 6, and the running gear 2 is in a contraction state in the vertical direction. The transport trolley 6 transports the working vehicle and the turnout 7 through obstacles.

Step S5: the operation vehicle adjusts the position of the turnout 7 through transverse movement, longitudinal movement and rotary movement, and completes the laying of the turnout 7.
