Technical Field
The invention belongs to the field of tunnel construction. More particularly, the invention relates to a high-efficiency mucking method for small-section tunnel construction.
Background
In the construction of the single-track railway tunnel, because the section of the tunnel is narrow, only 1 transport vehicle can be accommodated to pass through, and the distance of the foremost end of the tunnel is short due to the requirement of the operating step distance of the tunnel. Therefore, in the mucking link, two methods are available at present, the first method is to back the car from the tunnel entrance to the tunnel working surface, drive the car out of the tunnel after the mucking is finished, then back the car again to the tunnel working surface to load the mucking, and carry out the operation circularly. The method has the disadvantages of low mucking efficiency, long time and high requirement on the operation level of a vehicle driver. The second method is to arrange a car-avoiding hole in the tunnel, when a first car in the tunnel is loaded with ballast, a second car can drive to the car-avoiding hole in the tunnel from the outside of the tunnel in the forward direction, and then when the first car finishes loading the ballast and drives over the car-avoiding hole, the second car comes out of the car-avoiding hole, retreats to the working surface of the tunnel to load the ballast, and the operation is carried out in a circulating way. In both the first method and the second method, after one vehicle is filled with ballast and runs out, the other vehicle can enter the ballast, so that the loader cannot continuously operate, and the efficiency of the ballast discharging process in tunnel construction is low.
