Large-inclination-angle continuous muck discharge method used for subway tunnel construction

Abstract

The invention provides a large-inclination-angle continuous muck discharge method used for subway tunnel construction. The method includes the following steps that 1, when a shield machine moves forward for tunneling, a main machine belt conveyor is adopted for discharging muck which is dug out during tunneling; 2, the muck on the main machine belt conveyor is transferred to the tail part of a continuous belt conveyor; 3, the muck on the continuous belt conveyor is conveyed to the bottom of a shaft segment; 4, at the shaft segment, under the combined action of the continuous belt conveyor anda pressing belt part, the muck is conveyed to the ground surface at a large inclination angle; 5, on the ground surface, the continuous belt conveyor continues to extend to convey the muck to a machine head of the continuous belt conveyor for discharging. The method has the advantages that the continuous belt conveyor with a pressing belt can directly conduct conveying at a large inclination angle, there is no need to transfer the muck, the overall structure of equipment is simplified, and the efficiency is improved. By adopting two reels of adhesive tape for clamping materials, it is ensuredthat the materials cannot be leaked during conveying at the large inclination angle. Compared with a corrugated flange vertical-lifting belt conveyor, the method has the advantages that the cost is low, the reliability is high, and the effect of removing the muck on the adhesive tape is great.

Description

technical field [0001] The invention relates to a continuous belt conveyor, in particular to a method for continuously discharging slag at a large dip angle for subway tunnel construction. Background technique [0002] In the field of subway tunnel construction, the continuous belt conveyor can make the roadheader move forward continuously without stopping the machine. However, when the slag is discharged from the shaft, because the inclination angle is too large, the material will slide down, and the traditional continuous belt conveyor cannot be used for transportation. For slag, the combination of continuous belt conveyor + vertical lifting belt conveyor or continuous belt conveyor + hoist is generally used at present. The vertical lifting belt conveyor uses corrugated sidewall tape, which has a complex structure, is expensive, and is difficult to remove slag. The hoist has low efficiency and cannot continuously discharge slag. Therefore, the problem of large-inclination ...
