When the inclined shaft water collecting well 100 receives underground water drained by a drainage ditch and/or a transverse intercepting ditch 102, underground water drained by a positive line of a tunnel and/or underground water drained by a pump at the bottom of an inclined shaft, and collected underground water drained by a next-stage inclined shaft water collecting well 100 of the inclined shaft water collecting well 100 (namely, the underground water is located in the next inclined shaft water collecting well 100 of the inclined shaft water collecting well 100 along the descending direction of the inclined shaft), the received underground water firstly enters the first sedimentation tank 13, so that silt and impurities in the underground water are firstly precipitated to a certain degree; when the groundwater in the first sedimentation tank 13 passes through the drain port 151, the relatively clear groundwater enters the second sedimentation tank 14 through the drain port 151.

When the inclined shaft water collecting well 100 performs the reverse slope drainage, the sewage pump 31 is matched with the first water pumping pipe 41 and the first water drainage pipe 42 to pump and drain turbid underground water in the first sedimentation tank 13 into the first sedimentation tank 13 of the upper-stage inclined shaft water collecting well 100 of the inclined shaft water collecting well 100; if the inclined shaft water collecting well 100 is not provided with the next upper-level inclined shaft water collecting well 100, the sewage pump 31 is matched with the first water pumping pipe 41 and the first water draining pipe 42 to pump and drain the underground water in the first sedimentation tank 13 into the sedimentation tank at the inclined shaft hole. In addition, the submersible pump 32 cooperates with the second drain pipe 43 to pump and discharge relatively clear groundwater in the second sedimentation tank 14 into the first sedimentation tank 13 of the upper-stage inclined shaft water collecting well 100 of the inclined shaft water collecting well 100, or the submersible pump 32 cooperates with the second drain pipe 43 to pump and discharge relatively clear groundwater in the second sedimentation tank 14 into a designated water collecting well for secondary use; if the inclined shaft water collecting well 100 is not provided with the inclined shaft water collecting well 100 at the previous stage, the submersible pump 32 is matched with the second drain pipe 43 to pump and drain the underground water in the second sedimentation tank 14 into the sedimentation tank at the hole of the inclined shaft, or pump and drain the water in the second sedimentation tank 14 into the designated water collecting well, so as to carry out secondary utilization on the underground water in the second sedimentation tank 14.

In addition, the sewage pump 31 can play a certain sediment cleaning role for the first sedimentation tank 13 when pumping and draining the underground water in the first sedimentation tank 13, and the workload of workers for cleaning the sediment in the first sedimentation tank 13 is reduced; the submersible pump 32 can be used in cooperation with the first sedimentation tank 13 and the second sedimentation tank 14 to recycle relatively clear groundwater, and can replace the sewage pump 31 to pump and discharge groundwater when the sewage pump 31 fails.

Therefore, through the structural design of the inclined shaft water collecting well, the overall structural layout of the inclined shaft water collecting well is reasonable and standardized, the problems that the inclined shaft water collecting well is unreasonable in layout and poor in pumping drainage system operation effect in the existing inclined shaft anti-slope drainage system are thoroughly solved, efficient operation of the inclined shaft anti-slope drainage system is guaranteed through a scientific and reasonable structure, and construction safety is guaranteed.

Inclined shaft reverse slope drainage system embodiment

Referring to fig. 10, the inclined shaft reverse slope drainage system 90 includes an inclined shaft 96 and more than two inclined shaft water collection wells 97, and the more than two inclined shaft water collection wells 97 are distributed along the length direction of the inclined shaft. The inclined shaft water collecting well 97 is the inclined shaft water collecting well in the above embodiment of the inclined shaft water collecting well.

Therefore, the inclined shaft counter-slope drainage system provided with the inclined shaft water collecting well has a better drainage effect, the dredging difficulty of the inclined shaft water collecting well is reduced, and meanwhile, the inclined shaft counter-slope drainage system can realize graded sedimentation treatment on underground water.

Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the utility model are possible to those skilled in the art, without departing from the spirit and scope of the utility model.
