Abstract
The invention discloses a press-in type pump room. The press-in type pump room is characterized in that a completely-closed first cutoff wall (2), and an incompletely-closed second cutoff wall (3) are arranged between a pump room body (1) and a water sump; water pipes (10) are arranged at the lower ends of the first cutoff wall (2) and the second cutoff wall; the water pipe (10) at the lower end of the second cutoff wall is connected with a large-diameter steel water distributing pipe (5). According to the press-in type pump room, the water distributing pipe is used and replaces the traditional modes of distributing lane and collecting bin; the advantages of the press-in pump room are remained, the construction of a laneway of the pump room is decreased, so that the stress to the surrounding rock can be reduced, and as a result, the adverse influence of a large amount of arrangement projects surrounding the pump room on the stability of the surrounding rock can be decreased.
Description
Technical field
The present invention relates to a kind of pump room structure, particularly the pump room structure of forced water pump.
Background technology
Mine down-hole pump house arrangement pattern mainly contains forced and suction-type two kinds at present.Relative to suction-type, forced pump house water pump is lower than water bunker level, without the need to bottom valve, and pump efficiency is little compared with high power consumption, and compared with suction-type water pump, efficiency generally improves about 7%.In addition, utilize the water inlet of sump nature head not need startup of pouring water, cavitation erosion can be avoided, be conducive to automatically controlling and extending the water pump life-span.
The deficiency that forced pump house exists the mainly tunnel such as periphery water distribution drift, drain sump, inspection lane, chamber is more, engineering quantity (generally 20-30% bigger than normal than suction-type pump house) bigger than normal.Particularly when residing for pump house, location surrounding rock stability is poor, periphery arranges more chamber, tunnel simultaneously, makes force-bearing of surrounding rock mass situation comparatively complicated, is subject to the weathering of water, etch in addition, brings adverse effect can to pump house later maintenance.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of forced pump house, traditional water distribution drift and drain sump can be saved, both the advantage of forced pump house had been retained, reduce pump house well lane engineering again, reduce peripheral rock stress, reduce because of the more adverse effect brought to adjoining rock stability of pump house periphery engineering.
Technical scheme of the present invention is: a kind of forced pump house, the first completely airtight core wall and the second not exclusively airtight core wall is provided with between pump house and sump, first core wall and the second core wall lower end are provided with water pipe, the water pipe of the second core wall lower end is connected with Large-diameter Steel plasmogamy water pipe, and Large-diameter Steel plasmogamy water pipe is connected to water pump again.
Water pipe is provided with gate valve.The water pipe of the first core wall and the second core wall lower end is all configured with independently gate valve, the convenient adjustment to current and control.
There is grid between first core wall and the second core wall, the second core wall has ladder.Ladder is used for handled easily personnel and climbs up core wall observation, and the setting of grid both ensure that safety, and handled easily personnel process retaining between the first core wall and the second core wall again.
Described Large-diameter Steel plasmogamy water pipe is the steel pipe of more than caliber 500mm, specifically will decide according to the standage in each mine.
Underground drainage system of the present invention is made up of normal pump house and major and minor sump.Twice core wall is adopted to separate between pump house and major-minor sump.First core wall is located at apart from the sump at pump house about 5 meters of, and this core wall is completely airtight, plays impermeable role; Second core wall is arranged on pump house and sump adjacent, not exclusively airtight, and personnel can enter this section of sump top view regimen by ladder, plays the effect checking water level and carry out water distribution.Below twice core wall, drainage pipe and gate valve are all set, convenient closedown.By the discharge pipe line UNICOM in pump house between major and minor sump, and by gate valve and water pump UNICOM.Mine water is introduced into major and minor sump, then enters water pump by sump water distribution section, discharge pipe line and discharges down-hole.
The feature that the present invention gives prominence to eliminates water distribution tunnel, changes and carry out water distribution (substituting the water distribution drift of forced draining) by large diameter steel pipe, by reducing the well lane engineering of pump house periphery, improving surrouding rock stress distribution, reducing the superposition of pump house edge stress; Mine water is introduced into major and minor sump, then enters water pump by major diameter water distribution steel pipe road, finally discharges down-hole.
The present invention has played that forced pump house pump efficiency is high, and the simple advantage of later maintenance, in turn simplify pump house arrangement, decreases well lane engineering and investment, also reduces surrouding rock stress simultaneously and concentrates, favourable pump house later maintenance.
The present invention adopts distribution pipe to instead of traditional water distribution drift, drain sump way, both the advantage of forced pump house had been remained, additionally reduce pump house well lane engineering, reduce peripheral rock stress, decrease because of the more adverse effect brought to adjoining rock stability of pump house periphery engineering.Other corresponding mines are also extended to after the present invention's application maturation.

Fig. 2 is A-A schematic cross-section in Fig. 1.
Detailed description of the invention
As shown in Fig. 1 and Fig. 2, a kind of forced pump house, whole drainage system comprises pump house 1, major and minor sump, Large-diameter Steel plasmogamy water pipe 5, water pump 9, and the core wall between pump house 1 and major and minor sump forms.Core wall is provided with twice, and the first core wall 2 is arranged on apart from the sump at pump house 1 about 5 meters of, and this barricade is completely airtight, plays impermeable role; Second core wall 3 is arranged on pump house 1 and sump adjacent (with the first core wall 2 all at the homonymy of sump, but distance sump is more farther than the first core wall 2), and not exclusively airtight, the barrier 7 that personnel can be entered above this section of sump by ladder 4 observes regimen.Gutter 10 and gate valve 6 are all set below twice core wall, convenient closedown.Large-diameter Steel plasmogamy water pipe 5 is arranged on by sump side in pump house 1, and two ends connect major and minor sump respectively, by valve and water pump 9 UNICOM on outer gutter 8.During draining, mine water is introduced into major and minor sump, is then entered water pump 9 discharged by water distribution section (sump, and the first core wall 2 and the second core wall 3, water pipe 10), Large-diameter Steel plasmogamy water pipe 5.
For the white rock phosphorus ore in Wengan, the design of this ore deposit installs 5 550kw motor and water pumps in the pump house of down-hole 720.Because this mine following peripheral country rock is comparatively broken, pump house periphery should not arrange too much well lane engineering, by taking aforementioned arrangement, can reduce well lane engineering 40m compared with the forced pump house of routine; And compared with conventional suction-type pump house, calculate by normal 2 pump workings 10 hours every day, year can power cost saving 28.1 ten thousand Kwh, and power savings is very remarkable.
