Abstract

The utility model provides a big gun hole negative pressure drainage device for opencut rock burst is broken. Comprise five parts, the first portion is the negative pressure generater, and its principle is that high -pressure high velocity gas is introduced from the air inlet in succession to the during operation, and the gaseous interior air particle of bifurcated pipe of taking away when the branching is partial makes its internal pressure reduce the formation negative pressure rapidly, the second portion is the filter, and main effect is the stone that filters the hole bottom, prevents that great stone from getting into the drain pipe and taking place to block up, the third part is the plastic spring hose, is the drainage channel who couples negative pressure generater and the downthehole filter of big gun, the fourth part is the air compressor machine, and main effect provides high -pressure high velocity gas, the 5th part is the leading water pipe, and the assigned position is guided to by the leading water pipe with ponding after discharging to ponding, can not destroy site environment, also can not take place the condition of ponding refluence.

Description

A kind of big gun hole negative-pressure drainage device for outdoor rock blasting

Technical field

The utility model is for the draining processing of outdoor rock blasting big gun hole ponding.

Background technology

Outdoor rock blasting often can run into rainfall or inner infiltration of rock mass causes the situation of bottom, big gun hole certain depth ponding; can cause the even situation generation such as big gun hole plug, filling Quality Down of the explosive loading difficulties that non-waterproof explosive lost efficacy, density is less than water such as ammonium nitrate-fuel oil mixture due to big gun hole ponding, make the most at last the integrated cost of the increase of blasted material cost, demolition effect variation, explosion become large. The common methods solving at present has: the waterproof explosives such as the emulsion that (1) use cost is higher; (2) use air compressor machine to connect airduct and carry out hole bottom blowing water; (3) use the drainage equipment such as water pump to carry out draining. These methods have advantage separately, but method (1) will directly increase blasting cost; Method (2) can not directed draining, and water is blown out behind hole and scatters and trickle down at quick-fried area working face by high pressure gas, make working face muddyly can't bear to destroy construction environment, affect follow-up construction, and the water that part is discharged can flow backwards and cause draining not thorough in aperture; Method (3) is due to the extra procuring equipment of needs, and cost is high, and execute-in-place is more complicated also, and labor strength is large, and practical function is also undesirable.

Summary of the invention

In order to overcome the deficiency of above-mentioned technology, the utility model provides a kind of drainage arrangement, can convenient, effectively discharge big gun hole internal water accumulation.

The utility model solves the technical scheme that its technical problem adopts: structure is made up of five parts, Part I is negative pressure maker, when being work, its principle introduces continuously high-voltage high-speed gas from air inlet, when gas process forked section, take away the air particles in bifurcated pipe, make its internal pressure reduce rapidly formation negative pressure; Part II is filter, and Main Function is the stone at the bottom of filtering holes, prevents that entering drainpipe compared with ratchel stops up; Part III is plastics spring flexible pipe, is the drainage channel that connects negative pressure maker and big gun hole internal filter; Part IV is air compressor machine, and Main Function is to provide high-voltage high-speed gas; Part V is aqueduct, and ponding is guided to assigned address by aqueduct by ponding after discharging. When draining, the high-voltage high-speed gas that air compressor machine produces is introduced in negative pressure maker by airduct, make the air pressure in plastics spring flexible pipe reduce rapidly formation negative pressure, now in pipe and in big gun hole, mineralization pressure is poor, rely on atmospheric effect that the ponding in big gun hole is pressed in plastics spring flexible pipe, and blown out by gases at high pressure through the discharge outlet of negative pressure maker, the hole internal water accumulation of discharging can enter according to field condition the place of catch pit or appointment,, can there is not the situation that ponding flows backwards in the environment that can not destory the scene yet.

The beneficial effects of the utility model are, can not only discharge big gun hole ponding, and simple in structure, be easy to workman's execute-in-place, can directed draining, easy to carry, with low cost.

Brief description of the drawings

Fig. 1 is structure composition schematic diagram of the present utility model.

Fig. 2 is negative pressure maker structural representation.

Fig. 3 is filter structure schematic representation.

1. negative pressure makers in figure, 2. filter, 3. plastics spring flexible pipe, 4. air compressor machine, 5. aqueduct, 6. big gun hole, 7. air inlet, 8. negative pressure water sucking mouth, 9. discharge outlet, 10. interface, 11. filter grids.

Detailed description of the invention

After being connected with filter (2), plastics spring flexible pipe (3) sends into bottom, ponding big gun hole, then the negative pressure water sucking mouth (8) of negative pressure maker (1) is connected with plastics spring flexible pipe (3), aqueduct (5) is connected with the discharge outlet (9) of negative pressure maker (1), and air compressor machine (4) is connected with the air inlet (7) of negative pressure maker (1) by airduct. Start air compressor machine, now the gas of high-voltage high-speed is sent into negative pressure maker (1) by airduct, in plastics spring flexible pipe (3), produce rapidly negative pressure, utilize the inside and outside atm difference of plastics spring flexible pipe (3), hole prodelta clay hydraulic pressure is entered in plastics spring flexible pipe (3), discharge from discharge outlet (9), through aqueduct (5), ponding is discharged into assigned address.

Claims
