Abstract

PROBLEM TO BE SOLVED: To prevent deterioration of working environment in a tonnel, attain cost reduction, and alleviate the limit of passage of vehicles therein. SOLUTION: Earth and sand cut by a cutting edge 3 in a tonnel 2 is put in a carrying container 6, which is conveyed with a transport vehicle 7 to a runnable crusher 5, and the container is raised and inclined by a charge-in device installed in the crusher 5 and the earth and sand therein is charged into the crusher 5, and crushed thereat. The crushed earth and sand is delivered outside of the tonnel 2 from the crusher 5 by the use of a belt conveyer 9. Accordingly, in comparison with the case where a plurality of damp truck are made to run across almost the whole length of the tonnel 2 for deliverying the crushed earth and sand outside thereof, exhaust gas, dust, etc., discharged in the tonnel 2 is reduced, and the cost for maintenance of road surface in the tonnel 2 can be reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unloading method and equipment for unloading earth and sand such as shears in a tunnel.

[0002]

2. Description of the Related Art Conventionally, sediment such as shear generated from a face in a tunnel is loaded on a large number of dump vehicles, and the dump vehicles are run to carry the earth and sand out of the tunnel.

[0003]

However, in the above-mentioned conventional type, since a large number of dump vehicles travel in the tunnel over the entire length, the traveling distance becomes extremely long.
There has been a problem that exhaust gas, dust, and the like are discharged into the tunnel, thereby deteriorating the working environment. In addition, it was necessary to maintain the road surface in order to reduce the time required for the dump vehicle to be carried out. Furthermore, in a tunnel, traffic of vehicles other than the dump vehicle is greatly restricted, and when the entire length of the tunnel is very long, driver fatigue of the dump vehicle has increased.

[0004] The present invention provides a method for carrying out sediment in a tunnel and a method for carrying out sediment in a tunnel, which can prevent the working environment in the tunnel from deteriorating, reduce costs, and alleviate restrictions on traffic of vehicles in the tunnel. The purpose is to provide equipment.

[0005]

Means for Solving the Problems To achieve the above-mentioned object, the invention according to claim 1 of the present invention puts earth and sand generated from a face in a tunnel into a container for transportation, and allows the vehicle to be transported. The above-mentioned transport container is transported to the crusher by using, and the earth and sand in the transport container is thrown into the crusher by the input device to be crushed, and the crushed earth and sand is transported out of the tunnel using the transport device. It is characterized by doing.

According to this, the crusher is installed behind the face, and the earth and sand is carried out of the tunnel by the transport device on the downstream side from the crusher, so that the transport vehicle needs a short distance between the face and the crusher. It is only necessary to travel, so that exhaust gas, dust and the like discharged into the tunnel can be reduced as compared with the conventional case where a large number of dump vehicles travel around the entire length of the tunnel. Further, since the transport vehicle only needs to travel between the face and the crusher, the road surface maintenance cost in the tunnel can be kept low, and the restriction on the traffic of the vehicle in the tunnel can be eased.

According to a second aspect of the present invention, the earth and sand in the transport container transported by the transport vehicle is injected into an inlet of the crusher by an input device provided in the crusher, and the input earth and sand is crushed. The crushed earth and sand is discharged from the inside of the crusher main body to the transfer device by a discharge device provided in the crusher.

According to a third aspect of the present invention, a movable crusher for crushing the earth and sand is installed behind the face in the tunnel, and the earth and sand generated from the face is transported to the crusher via a transport container. A transporting vehicle, a loading device for loading the earth and sand in the transport container into the crusher, and a transport device for transporting the soil crushed by the crusher out of the tunnel. A crusher body for crushing, an inlet for taking in earth and sand into the crusher body, a discharge device for discharging the crushed earth and sand from the inside of the crusher body to a transport device, and a traveling device for running the crusher body. Wherein the charging device is provided in the crusher, lifts and tilts the transport container, and loads the earth and sand in the transport container into the inlet.

According to this, the earth and sand generated from the face are put into a transport container, the transport container is transported to a crusher using a transport vehicle, and the transport container is lifted and tilted by an input device to transport the container. The earth and sand inside the crusher is introduced into the inlet of the crusher, crushed by the crusher body, and the crushed earth and sand is discharged from the crusher body to the conveyor by the discharge device, and the discharged earth and sand is discharged from the tunnel by the conveyor. It is carried out.

At this time, the crusher is positioned behind the face,
On the downstream side from the crusher, the hauling vehicle has to travel only a short distance between the face and the crusher, because the earth and sand is carried out of the tunnel by the transport device, and therefore, a large number of dump vehicles as in the conventional case The exhaust gas, dust and the like discharged into the tunnel can be reduced as compared with the case where the vehicle travels over almost the entire length of the tunnel. Also, since the transport vehicle only needs to travel between the face and the crusher, the road surface maintenance cost in the tunnel can be kept low, and furthermore,
Restrictions on traffic of vehicles in the tunnel can be relaxed.

In addition, as the tunnel is dug, the position of the face is gradually displaced to the rear of the tunnel. In response to this, the crusher is driven to the rear of the tunnel by the traveling device, so that the crusher is almost always moved away from the face. The crusher can be located rearward by a certain distance, and the distance from the face to the crusher can be prevented from becoming extremely large.
