Abstract

The present application belongs to the technical field of tunnel construction, in particular to a combined slagging-off device and method for super-large and super-deep vertical shafts. After the rock is broken by the cutter head during tunneling, the rock slag is suspended by injecting bentonite mud slurry at the cutter head position. The mud slurry and rock slag are separated at the mud-water separation station of the mud-water treatment platform of the vertical tunneling machine. The separated rock slag is lifted to the ground by a bucket. The mud slurry is returned to the cutter head position through the mud return pipeline for repeated use. The excess mud slurry is discharged to the ground mud pool for subsequent use. This method is effective for super-large and super-deep vertical shafts using tunneling machine equipment for slagging-off. Conventional methods such as air-lift reverse circulation, vertical belt conveyor, and mud slurry pump slagging-off cannot be used for super-large and super-deep vertical shafts due to limitations such as mud slurry level, vertical transportation distance, and environmental protection. The above conditions are solved, which can greatly improve the overall construction efficiency and realize continuous operation.

Under the pressure of the top rod 11, the arc-shaped bracket 12 will drive the deflection plate 10 to rotate at a certain angle, so that the deflection plate 10 will be in a deflected state. The rock slag on the surface of the deflection plate 10 will slide down to the cavity between the filter cylinder 3 and the supporting table 6 along the inclined surface as soon as possible, improving the processing efficiency of the rock slag;

[0051] The elastic pressing rod 13 is arranged, which is favorable to support the deflection plate 10 and facilitate the deflection plate 10 to bend and recover; when the supporting table 6 moves to the side close to the jacking rod 11, the jacking rod 11 will contact and press the inclined surface of the inclined seat 15, so that the inclined seat 15 moves on the outer surface of the horizontal rod 14 at a certain distance, and the inclined seat 15 will push the rock slag to one side of the cavity of the filter cartridge 3 as soon as possible under the action of the dispersing rod 16; the elastic extrusion rod 17 is arranged, which is favorable to the recovery of the inclined seat 15 and facilitates the dispersing rod 16 to shake at a certain amplitude, so that the rock slag on the upper surface of the deflection plate 10 is in a dispersed state, so that more rock slag can be contained; during the movement of the dispersing rod 16, the arc shape on one side of the dispersing rod 16 will contact the arc shape at one end of the pressure plate 19, so that the pressure plate 19 is pressed and rotates at a certain angle, at this time, the limiting spring 191 is in a compressed state, and the dispersing rod 16 and the pressure plate 19 continue to compress, so that the two slowly separate, so that the limiting spring 191 is no longer compressed, and under the recovery of the limiting spring 191, the pressure plate 19 will move at a high speed, so that the pressure plate 19 pushes the rock slag on the bottom side of the deflection plate 10, avoids the problem that the rock slag is difficult to handle due to too much mud, is favorable to the concentrated treatment of the rock slag, and is convenient for the excavation of the shaft.
