Abstract
The utility model discloses a water injection apparatus of water blasting, comprising a header pipe and water injection flexible pipes which are arranged in blast holes and are used for injecting water, and the number of the water injection flexible pipes is the same with that of the blast holes. The header pipe is provided with branch pipes used for being correspondingly connected with the water injection flexible pipes; the water injection flexible pipes are provided with water injection one-way valves; and the branch pipes are all provided with flow control valves used for adjusting water supply flow. The water injection apparatus of water blasting has a relatively strong adaptability; only the header pipe needs to be injected with water; opening degree of the flow control valve is adjusted in advance, according to water injection amount of each blast hole; the header pipe is closed when the water injection is completed; at the same time, the water injection flexible pipes are separated with the header pipe; the water injection flexible pipes are left at the blast holes; water in the blast holes does not flow out, because of the effect of the one-way valve; and water injection in all the blast holes are completed at the same time, so that water injection can be relatively fast realized, blasting efficiency is increased, gas temperature in a tunnel can be rapidly and effectively reduced during the blasting process; blasting can be prevented; simultaneously respiratory dust and harmful gas can be reduced; and security and environmental protection during the blasting process are guaranteed.
Description
Technical field
The utility model relates to the roadway engineering technical field, is specifically related to a kind of quick water filling device when adopting the waterinfusion blasting method when being used for tunnelling, belongs to blasting technique.
Background technology
Waterinfusion blasting is that the quick-fried medicine of borehole is filled in a bit of stemming earlier, and then fills out a bit of stemming to heel and fill in, and thin water injection pipe water filling is inserted in the space between two sections stemmings, fills with the back and extracts water injection pipe out, and will begin explosion after the obstruction of the aperture on the stemming.In blasting process, the water in the big gun hole helps reducing the temperature of methane gas in the tunnel, prevents blast, and water is vaporized under HTHP simultaneously, condenses with the explosion dust, reaches the purpose of depositing dust, and ensuring respiration property dust content has bigger minimizing; Can also reduce the pernicious gas that explosion produces, shorten the explosion rear venting time in the tunnel, increase work efficiency.
In the prior art, need the independent water filling of each borehole, the water yield that each borehole needs might not be identical, and water injection rate is mainly by the subjective control of people, uncontrollable water injection rate, so waterinfusion blasting method water injection time is long, the water filling quality is uneven, influences blasting efficiency.Therefore, most collieries are still adopted water stemming material and are not had the waterinfusion blasting method in the prior art, but the water yield of bubble mud is unfavorable for reducing the gas temperature and prevents the explosion dust less than the water injection rate of waterinfusion blasting; Simultaneously, bubble mud is just used the polybag from enclosuring structure, should have difficult combustion and nontoxic characteristics, and certain intensity is arranged, thereby cost is higher relatively.
Therefore, need improve existing waterinfusion blasting water flooding regime, can realize very fast water filling, improve blasting efficiency, be beneficial to the temperature that reduces methane gas in the tunnel fast and effectively in the blasting process, prevent blast, reduce respirable dust and pernicious gas simultaneously, guarantee the safety and and the feature of environmental protection in the blasting process.
The utility model content
In view of this, the purpose of this utility model provides a kind of waterinfusion blasting water filling device, can realize very fast water filling, improve blasting efficiency, be beneficial to the temperature that reduces methane gas in the tunnel fast and effectively in the blasting process, prevent blast, reduce respirable dust and pernicious gas simultaneously, guarantee the safety and and the feature of environmental protection in the blasting process.
Waterinfusion blasting water filling device of the present utility model comprises that house steward is identical with borehole with quantity and place the water filling flexible pipe that is used for water filling in the borehole, and described house steward is provided with the arm that is used for the corresponding connection of water filling flexible pipe, and described water filling flexible pipe is provided with the water filling one way valve; Described arm is equipped with the flow control valve that is used to regulate water supply flow.
Further, described water filling one way valve is the diaphragm type one-way valve that is arranged at water filling flexible pipe water side;
Further, described flow control valve is a needle valve;
Further, described water filling flexible pipe is connected by the mode of pegging graft with the water side of arm;
Further, the water side of arm is provided with and is used for the back-off that matches with the water filling flexible pipe;
Further, the fixing pipe clamp of the flexible opening of pipeline section peripheral hardware that matches with the water side of arm of described water filling flexible pipe;
Further, described flow control valve is provided with the Flow-rate adjustment scale.
The beneficial effects of the utility model are: waterinfusion blasting water filling device of the present utility model, adopt house steward and corresponding with borehole quantity and be used for the water filling flexible pipe of water filling, the water filling flexible pipe is connected with house steward is detachable, by the independent regulating pondage of flow control valve separately, compliance is stronger, during water filling, only need by house steward's water filling, adjust the aperture of flow control valve in advance according to the water injection rate of each borehole, water filling is finished and is then closed house steward, simultaneously the water filling flexible pipe is separated with house steward, and the water filling flexible pipe is kept somewhere in borehole, because the effect of one way valve, water in the borehole can not flow out, and the water filling simultaneously of each borehole is finished, and can realize very fast water filling, improve blasting efficiency, be beneficial to the temperature that reduces methane gas in the tunnel fast and effectively in the blasting process, prevent blast, reduce respirable dust and pernicious gas simultaneously, guarantee in the blasting process safety and and the feature of environmental protection, the tunnelling progress is not subjected to obviously to influence when guaranteeing to adopt the waterinfusion blasting method.
