Description
Technical field
The utility model relates to rock-boring blasting technique fields, more particularly to a kind of stifled dress of rock-boring implication press seal
It sets.
Background technique
Traditional rock blasting is needed using explosive, but explosive blasting technical requirements are high；Noise and vibration is difficult to control；Meeting
Generate toxic gas.Start to develop a kind of method for combining shot rock with internal water pocket with external pressure, patent Shen in recent years
It please number be 201610259726.6, this method is first put into water pocket in rock-boring, and the snorkel that is connected with high pressure gas cylinder is inserted into
After rock-boring, to guarantee that air pressure does not leak, hell is blocked using fast hardening concrete, not only inefficiency, but also snorkel
It is difficult to reuse, for this reason, it may be necessary to a kind of rock-boring implication press seal block apparatus of utility model.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of stifled dress of rock-boring implication press seal
It sets, the instantaneous air pressure plugging effect of the utility model is good, quick for installation, convenient disassembly, reusable.
Purpose of the utility model is realized as follows:
A kind of rock-boring implication press seal block apparatus, including snorkel, cover the outer tube in snorkel lower part, and cover
Flexible pipe between outer tube, snorkel, the lower part of the flexible pipe extended the lower part of outer tube, snorkel, the ventilation
The lower section of pipe is equipped with gas block panel, and the diameter of the gas block panel is less than the aperture of snorkel, the gas block panel and snorkel inner end it
Between be fixedly connected by several dowels, formed headroom between adjacent dowel.
Preferably, the flexible pipe forms interference fit between outer tube, snorkel respectively.
Preferably, the material of the flexible pipe is silica gel.
Preferably, the snorkel, outer tube, gas block panel, dowel are steel.
Preferably, the dowel is welded and fixed with snorkel, gas block panel respectively.
Preferably, the gas block panel is circle, and coaxial with snorkel.
A kind of rock-boring implication press seal blocking method, including plugging device, are put into the drilling equipped with water pocket for plugging device
Aperture, and it is passed through high pressure gas from snorkel, high pressure gas pours in drilling from headroom is crossed, and the lower part of flexible pipe is in high pressure gas
Elastic deformation occurs to the hole wall direction of drilling under the action of body, the pipe thickness of flexible pipe lower part is made to become smaller, internal diameter increases, soft
Property pipe lower part outer wall be bonded to form sealing with the hole wall of drilling, make to form an annular between the lower part of flexible pipe, snorkel
Space；
High pressure gas in drilling generates the thrust outside drilling to plugging device, and active area is the annular space
Sectional area, meanwhile, high pressure gas generates a thrust into drilling to gas block panel, and active area is the face of gas block panel
Product, the thrust to outside drilling are cancelled out each other with the thrust into drilling.
Preferably, the area equation of the sectional area of the annular space and gas block panel.
By adopting the above-described technical solution, the utility model has the following beneficial effects:
1. instantaneous air pressure plugging effect is good, quick for installation, convenient disassembly, reusable rotary rock drill port closing dress
It sets；
2. being applied to external pressure to combine in the construction of shot rock with internal water pocket, it is quick-fried that rock not only can be improved
Broken construction efficiency, can also save economic cost, have apparent engineering value and social benefit.
Detailed description of the invention
Fig. 1 is that a kind of rock-boring implication press seal block apparatus is passed through the structural schematic diagram before high pressure gas；
Fig. 2 is that a kind of rock-boring implication press seal block apparatus is passed through the structural schematic diagram after high pressure gas；
Fig. 3 is the cross-sectional view of Fig. 2.
Appended drawing reference
In attached drawing, 1 is drilling in figure, and 2 be water pocket, and 3 be annular space, and 4 be snorkel, and 5 be round gas block panel, and 6 be to connect
Muscle is connect, 7 be flexible pipe, and 8 be outer tube.
Specific embodiment
Referring to Fig. 1, a kind of rock-boring implication press seal block apparatus, including snorkel, the outer tube in snorkel lower part is covered,
And flexible pipe between outer tube, snorkel is covered, the material of the flexible pipe is silica gel.The flexible pipe respectively with housing
Interference fit is formed between pipe, snorkel.The lower part of the flexible pipe extended the lower part of outer tube, snorkel, the ventilation
The lower section of pipe is equipped with gas block panel, and the gas block panel is circle, and coaxial with snorkel.The diameter of the gas block panel is less than snorkel
Aperture, be fixedly connected between the gas block panel and snorkel inner end by several dowels, formed between adjacent dowel
Headroom.
The snorkel, outer tube, gas block panel, dowel are steel.The dowel respectively with snorkel, gas block panel
It is welded and fixed.
Referring to figures 1-3, it is a kind of rock-boring implication press seal blocking method, including plugging device, plugging device is put into
Drilling orifice equipped with water pocket, and it is passed through high pressure gas from snorkel, high pressure gas pours in drilling from headroom is crossed, flexible pipe
Lower part under the action of high pressure gas to the hole wall direction of drilling occur elastic deformation, become the pipe thickness of flexible pipe lower part
Small, internal diameter increases, and the outer wall of flexible pipe lower part is bonded to form sealing with the hole wall of drilling, the work of the top of flexible pipe in outer tube
Deformation occurs under, forms ladder between the lower part of flexible pipe, top, so make the lower part of flexible pipe, ventilation pipe outer wall it
Between formed an annular space；
High pressure gas in drilling generates the thrust outside drilling to plugging device, and active area is the annular space
Sectional area, meanwhile, high pressure gas generates a thrust into drilling to gas block panel, and active area is the face of gas block panel
Product, when the area of round gas block panel is equal with the sectional area of the annular space, then pushing away to outside drilling suffered by device
Power is equal with the thrust into drilling, and the thrust to outside drilling is cancelled out each other with the thrust into drilling, and plugging device can be protected
It is fixed to keep steady, and flexible pipe is closely affixed with the wall of a borehole under gas pressure, instantaneously can effectively block air pressure.
After under external pressure and internal water pocket synergy explosion occurs for rock, device can efficiently and easily be taken out,
For next rock-boring explosion.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
