Description
Technical field
The utility model relates to a kind of arragement constructions of sub-terrain mines sump, belong to mine construction technical field.
Background technique
In Underground mine design process of construction, drainage system is one of important system, and sub-terrain mines Water drainage system design
Core is the selection of pump house, sump and draining pump, because of the presence of centrifugal water pump allowable suct lift and water erosion, because
This, when Water drainage system design, limits the relative height differential of sump minimum discharge level and the Pump Suction mouth of a river, to limit water
Storehouse fluctuation in stage difference in height, the i.e. effective height of sump.For the daily drainage requirement for meeting mine water inrush amount, it can only widen, add
It is long, increase sump quantity perhaps select the water pump of higher performance so as to cause wellhole range is larger or equipment investment compared with
Height limits Underground mine design space.In addition, after discharge level decline, the water erosion be easy to causeing and drainage efficiency decline etc.
Problem.Therefore, it is necessary to optimize to it, the range of sump scope of design and water pump selection is widened.
Utility model content
The purpose of the utility model is to provide a kind of arragement constructions of sub-terrain mines sump, can satisfy the day of mine water inrush amount
Normal drainage requirement, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of arragement construction of sub-terrain mines sump includes core wall, sump, pump house, core wall drainage tube, pumping drainage
Pipeline, pump motor basis, motor, centrifugal pump, water sucking mouth and valve, core wall are arranged between sump and pump house, water
Pump motor basis is equipped in pump house, motor and centrifugal pump are separately fixed on the basis of pump motor, motor and centrifugal pump
It is drivingly connected, centrifugal pump has discharge outlet and water sucking mouth, and pumping drainage pipeline is connected in the discharge outlet of centrifugal pump, and core wall draws
One end of flow tube is connected on the water sucking mouth of centrifugal pump, and the other end of core wall drainage tube passes through core wall and connect with sump, institute
The absolute altitude for stating sump bottom is higher than the absolute altitude of centrifugal pump water sucking mouth, and core wall drainage tube is equipped with valve.
The core wall drainage tube is connected to the bottom of sump.
The height of the core wall is greater than the height of sump, and the width of core wall is greater than the width of sump and pump house.
Keep the two wrong up and down since the absolute altitude of sump bottom is higher than the absolute altitude of centrifugal pump water sucking mouth using the utility model
It opens, after sump water storage, is automatically flowed by water pressure into water pump, no longer limitation water pump allowable suct lift, to widen
Model of pump range of choice, at the same water pump allowable suct lift and sump profile height is separated, allow sump to design
Parameter is freer, more realistic needs.
The beneficial effects of the utility model are: breaching the Traditional Thinking that pump house and sump are laid, allow for water pump
Suction vacuum limits the selection range problem of sump design height parameter and Model of pump, takes raising sump relatively high
Degree changes pump sump mode, to widen the range of sump scope of design and water pump selection, while also avoiding because of draining
Water erosion caused by after water level decreasing and drainage efficiency decline phenomenon.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: core wall 1, sump 2, pump house 3, core wall drainage tube 4, pumping drainage pipeline 5, pump motor basis 6,
Motor 7, centrifugal pump 8, water sucking mouth 9, valve 10.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1, a kind of arragement construction of sub-terrain mines sump is drawn comprising core wall 1, sump 2, pump house 3, core wall
Flow tube 4, pumping drainage pipeline 5, pump motor basis 6, motor 7, centrifugal pump 8, water sucking mouth 9 and valve 10, core wall 1 are arranged
Between sump 2 and pump house 3, pump motor basis 6 is equipped in pump house 3, motor 7 and centrifugal pump 8 are separately fixed at water
On pump motor basis 6, motor 7 and centrifugal pump 8 are drivingly connected, and centrifugal pump 8 has discharge outlet and water sucking mouth, pumping drainage pipeline
5 are connected in the discharge outlet of centrifugal pump 8, and one end of core wall drainage tube 4 is connected on the water sucking mouth of centrifugal pump 8, and core wall draws
The other end of flow tube 4 passes through core wall 1 and connect with sump 2, and the absolute altitude of 2 bottom of sump is higher than the mark of 8 water sucking mouth of centrifugal pump
Height, core wall drainage tube 4 are equipped with valve 10.
In the present embodiment, referring to attached drawing 1, it is isolated between sump 2 and pump house 3 with armored concrete core wall 1,
When construction, it should ensure that 2 elevation of bottom of sump is at least above the water sucking mouth 9 of centrifugal pump 8, core wall drainage tube 4 is cast in core wall 1
It is interior, it is close to the bottom of sump 2, it is ensured that realize that the water in sump 2 can be flowed out all by core wall drainage tube 4 certainly, core wall 1
Height and width should the boundary 1m or more beyond sump 2, pump house 3, the thickness of core wall 1 will meet 2 hydrostatic pressure of sump
With underground waterproof requirement, the construction quality of core wall 1 requires to be ne-leakage, meets mine construction inspection of quality specification.
After 2 water storage of sump, valve 10 is opened, water flow passes through core wall 1 under the effect of the pressure, through core wall drainage tube 4
Automatically centrifugal pump 8 is filled, after starting motor 7, centrifugal pump 8 can be driven, water is drained into earth's surface by pumping drainage pipeline 5.
