Description
TOP MUCK DISCHARGE SYSTEM AND METHOD OF SHAFT FULL-FACE
BORING MACHINE
FIELD OF TECHNOLOGY
The present invention relates to a top muck discharge system and method of a shaft full-face boring machine, and belongs to the technical field of underground engineering construction.
Efficient and continuous top muck discharge during full-face boring machine construction in a shaft, particularly in a deep shaft has become a current key shaft technical problem at home and abroad, resulting in low deep shaft construction efficiency.
A first traditional muck discharge mode adopts a cyclic slurry discharge mode. A certain proportion of slurry is adopted therein to wrap muck to be elevated and transported by a slurry pump, and then the slurry returns to a working face to be cyclically used. The slurry in a shallow shaft (100 m) can be directly transported to the ground; and a plurality of sets of relay stations are required to be disposed in a medium shaft and the deep shaft to transport the slurry to the ground through relay. The first traditional muck discharge mode has the defects that slurry cycle efficiency is low, and energy consumption is high; large-scale muck is likely to block pipes, causing a high fault rate; due to a limited shaft space, it is difficult to arrange the relay stations, and reliability is poor; and a plurality of chemical agents are added in the slurry, which hardly satisfies environment protection requirements.
A second traditional muck discharge mode is a mode combining a first-level muck pump and a second-level lifting bucket. A water-muck separation apparatus is required to be disposed on a hoist, the muck pump conveys water and the muck into the water-muck separation apparatus on the hoist in a short distance, and a winch drives the bucket to transport the muck obtained after separation to the ground. The second traditional muck discharge mode has the defects that process automation is hard to implement in bucket transportation; and there are generally many links, complex procedures, and many devices which are not continuous; muck discharge efficiency is low; and energy consumption is high.
In order to overcome the defects in the prior art, an objective of the present invention is to provide a top muck discharge system and method of a shaft full-face boring machine, thereby effectively solving the existing problems.
The present invention adopts the following technical scheme for solving the technical problems:
A top muck discharge system of a shaft full-face boring machine includes: a first-level muck discharge unit, a second-level muck discharge unit and a control system; the first-level muck discharge unit includes a first-level muck pump and a first-level muck discharge pipeline, the first-level muck pump is disposed in a boring machine cutterhead, and multi-scale muck and water are upwardly discharged to the second-level muck discharge unit through the first-level muck discharge pipeline; the second-level muck discharge unit includes a water-muck separation device, a crushing device, a grinding device, a slurry bin and a second-level muck pump which are disposed from top to bottom; an inlet of the water-muck separation device communicates with the first-level muck discharge pipeline, a muck outlet communicates with the crushing device, and a water outlet communicates with the slurry bin; an inlet of the grinding device communicates with the muck outlet of the water-muck separation device, and an outlet of the grinding device communicates with the slurry bin; and slurry in the slurry bin is pumped, by the second-level muck pump, to the ground.
Preferably, further, a settling pond is disposed on the ground and communicates with a second-level muck discharge pipeline of the second-level muck pump, a partition is disposed in the settling pond, and clear water passing through the partition returns, by a water return pipeline, to a driving face to be cyclically utilized.
Preferably, further, the slurry bin further communicates with a water supply pipe, a stirring apparatus, a high-liquid-level sensor, a low-liquid-level sensor and a slurry concentration sensor are further disposed in the slurry bin, and the sensors and an electromagnetic valve controlling opening and closing of the water supply pipe are all electrically connected to the control system.
Preferably, further, muck having a granularity less than or equal to 0.4 mm and water in the water-muck separation device directly enter the slurry bin through a pipeline.
Preferably, further, muck having a muck granularity less than 8 mm after being crushed in the crushing device enters the grinding device.
Preferably, further, muck having a muck granularity less than 0.4 mm after being ground in the grinding device enters the slurry bin to be stirred into slurry to be pumped, by the second-level muck pump, to the settling pond.
A method for adopting the above top muck discharge system to perform shaft top muck discharge includes following steps:
S1: arranging the first-level muck pump in an inner cavity of the boring cutterhead of a boring machine, and connecting the first-level muck discharge pipeline to the water-muck separation device;
S2: suspending the multi-layer hoist for construction in the boring shaft, arranging the second-level muck pump, the slurry bin, the grinding device, the crushing device and the water-muck separation device on different layers of the hoist, and arranging the water supply pipe for the slurry bin;
S3: making the second-level muck discharge pipeline of the second-level muck pump communicate with the settling pond, and returning, by the water return pipeline, the clear water of the settling pond to the driving face;
S4: making muck generated in the boring process of the boring machine fall into the inner cavity of the boring cutterhead to be mixed with the water returned from the settling pond to form multi-scale slurry, and pumping, by the first-level muck pump, the slurry into the water-muck separation device when the slurry reaches a set depth;
SS: making muck having a granularity less than or equal to 0.4 mm and water in the water-muck separation device directly enter the slurry bin, making large-scale muck enter the crushing device, making muck having a muck granularity less than 8 mm after being crushed enter the grinding device, making muck having a muck granularity less than 0.4 mm after being ground enter the slurry bin to be stirred, by the stirring apparatus, into slurry in the slurry bin together with water supplied by the water supply pipe, and controlling opening and closing of a valve in the water supply pipe according to signals fed back by the slurry concentration sensor in the slurry bin, thereby controlling the slurry to be constantly kept in a set concentration range;
S6: controlling opening and closing of an outlet valve of the slurry bin by signals fed back by the high-liquid-level sensor and the low-liquid-level sensor in the slurry bin, such that slurry with proper concentration flows to the second-level muck pump from a slurry bin outlet and is pumped to the settling pond via the second-level muck discharge pipeline ; and
S7: making the deposited muck truck-loaded and transported to a utilization place, and returning the clear water obtained after sedimentation to the driving face through the water return pipeline (32), and repeating the process.
Compared with the prior art, the present invention has the following beneficial effects:
After the present invention adopts the first-level muck pump to vertically elevate the multi-scale muck to the second-level muck discharge unit on the hoist in a short distance according to the characteristics of the high proportion of small-scale muck and the low proportion of the large-scale muck during full-face boring machine construction, the large-scale muck is crushed and ground into the small-scale muck through classified crushing to be directly conveyed together with previous separated small-scale muck to the ground through the high-lift muck pump. The present invention solves the problem that it is difficult to arrange relay stations in a shaft and the problem about system reliability; after the large-scale muck is removed, the problem of pipe blockage is effectively solved; a slurry cycle becomes a water cycle, and thus energy consumption is greatly reduced; and the muck discharge system can operate efficiently and continuously, which lays a solid foundation for intelligent and efficient shaft construction.
