Abstract

The utility model discloses a drainage device for constructing an inclined shaft. Intercepting ditches are arranged below the showering position of the inclined shaft and communicated through closed conduits, a coal stopping wall is arranged on the upper edge of the intercepting ditches, and water in the intercepting ditches is communicated to a water collecting bin after pasting through open channels and the closed conduits and drained to the ground uniformly by a water pump in the water collecting bin. The drainage device for constructing the inclined shaft solves the problems that according to an existing inclined shaft drainage system, a plurality of water bins and water pumps need to be arranged in a segmentation mode for a shaft with a long-distance inclined shaft, the drainage system is complicated in construction, and cost is high. The drainage device for constructing the inclined shaft is simple in structure, convenient to implement, and capable of reducing cost and improving driving speed of a coal mine.

Description

The dewatering installation of slope construction

Technical field

The utility model belongs to the mining technical field, relates to a kind of dewatering installation of slope construction.

Background technology

Usually needing to beat inclined shaft in coal mining, when mining work approaches or penetrates underground reservoir, often just have the trickle phenomenon and take place, cause the production safety accident, so how the water in the inclined shaft is effectively discharged, is the important topic of coal mine working.Existing slope construction water discharge method adopts segmentation sump pump drainage, and the water channel diversion is set between the sump, the corresponding water pump pump drainage diversion of each sump.For the pit shaft of inclined shaft distance, just need segmentation that a lot of sump and water pump are set, the drainage system construction is complicated, the engineering cost height; On the other hand, under the big operating mode of trickle amount, use above this method, can not accomplish effective draining, influenced the colliery driving speed.

Summary of the invention

The purpose of this utility model provides a kind of dewatering installation of slope construction, solves existing inclined shaft drainage system for the pit shaft of inclined shaft distance, and the drainage system construction is complicated, cost is high, influences the problem of colliery driving speed.

The technical scheme that the utility model adopts is, the dewatering installation of slope construction arranges catchwater below inclined shaft trickle position, and by the closed conduit conducting, place, the upper edge of catchwater arranges coal-stopping wall between the catchwater.

Characteristics of the present utility model also are,

Catchwater is by open channel and drain sump conducting.

Drain sump is connected with ground by gutter, is provided with water pump in the drain sump.

The angle of catchwater and inclined shaft center line is made as 80 degree or 100 degree.

The beneficial effects of the utility model are, the utility model correspondence below inclined shaft trickle position arranges catchwater, be conducting to drain sump by open channel, closed conduit again, unification is discharged to ground by the water pump in the drain sump, has overcome existing inclined shaft drainage system for the pit shaft of inclined shaft distance, need segmentation that a plurality of sump and water pump are set, cause the problem that the drainage system construction is complicated, cost is high, of the present utility model simple in structure, be convenient to implement, reduce cost, improved the driving speed in colliery.

Description of drawings

Fig. 1 is the structural representation of the dewatering installation of the utility model slope construction;

Fig. 2 is the A-A sectional view of Fig. 1;

Among the figure, 1. ground, 2. inclined shaft, 3. catchwater, 4. closed conduit, 5. gutter, 6. open channel, 7. drain sump, 8. water pump, 9. coal-stopping wall.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The utility model provides a kind of dewatering installation of slope construction, referring to Fig. 1 and Fig. 2, below inclined shaft 2 trickle positions, catchwater 3 is set, according to the trickle position what, several catchwaters 3 can be set, pass through closed conduit 4 conductings between each catchwater 3, the place, upper edge of catchwater 3 arranges coal-stopping wall 9, the water of catchwater 3 communicates by closed conduit 4, and coal-stopping wall 9 can block the coal slime in the water, makes things convenient for workman's cleaning.

Catchwater 3 is by open channel 6 and drain sump 7 conductings, and the water of each catchwater 3 finally is pooled in the drain sump 7 by closed conduit 4, open channel 6, is provided with water pump 8 in the drain sump 7, can be discharged to ground 1 to water by gutter 5 with pump 8 and get on.

803 meters of the length overalls of an existing inclined shaft, during work, be provided with 3 catchwaters 3 according to the trickle position, size according to the water yield, the size of catchwater 3 is made as 350*150*5400mm, and the size of closed conduit 4 is made as 150*150mm, sets up coal-stopping wall 9 at the place, upper edge of catchwater 3, according to what of slime content, the size of coal-stopping wall 9 is made as 300*150*5400mm; Angle near No. 1 catchwater of well head and No. 2 catchwaters and pit shaft tunnel center line all is made as 100 degree, is made as 80 near the angle of No. 3 catchwaters in shaft bottom and pit shaft tunnel center line and spends; Pass through closed conduit 4 conductings between each catchwater; No. 3 catchwaters are by

open channel

6 and 7 conductings of shaft bottom drain sump; Water pump 8 is set in the drain sump 7, the water in the drain sump 7 is discharged to ground 1 by water pump 8 from gutter 5 gets on.

By correspondence below inclined shaft trickle position catchwater is set, be conducting to drain sump by open channel, closed conduit again, unification is discharged to ground by the water pump in the drain sump, overcome existing inclined shaft drainage system for the pit shaft of inclined shaft distance, needed segmentation that a plurality of sump and water pump are set, caused the problem that the drainage system construction is complicated, cost is high, of the present utility model simple in structure, be convenient to implement, reduced cost, improved the driving speed in colliery.
