Put on the inwall of sealing sleeve pipe and be pressed between fixed plate and the annular boss of portable plate, lead between fixed plate and portable plate
Cross bolt connection；The connecting tube is coaxial with sealing sleeve pipe, and one end of connecting tube passes through the corresponding interface of flange and T-shaped tee T
Docking, the other end is connected with fixed plate.
Above-mentioned underground mine harness the river device for preventing blowout of drill holes, the orifice tube and aperture ball valve adpting flange between, aperture
Between the adpting flange of ball valve and T-shaped tee T, between T-shaped tee T and the adpting flange of connecting tube and T-shaped tee T with put
Sealing gasket is equipped between the adpting flange of water polo valve.
This utility model is provided with the anti-spraying mechanism of two-stage being made up of drill rod sealing device and aperture ball valve, when through two-stage
When the drill bit of anti-spraying mechanism touches water-bearing layer or major fault, first with drill rod sealing device the injection of retention of excessive fluid is suppressed, it is to be drilled
Head is withdrawn from after the ball valve of aperture and turns off aperture ball valve, and retention of excessive fluid is thoroughly shut, and the device not only can effectively prevent injected hole big
Amount water spray, and mortar depositing construction is not affected, so as to ensure that being smoothed out for mining production construction.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A direction views.
Respectively it is numbered in figure：1st, orifice tube, 2, aperture ball valve, 3, T-shaped tee T, 4, connecting tube, 5, fixed plate, 6, sealing
Sleeve pipe, 7, portable plate, 8, packing, 9, bolt, 10, water drain ball valve, 11, drill bit via.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, this utility model mainly include orifice tube 1, aperture ball valve 2, T-shaped tee T 3, connecting tube 4,
Fixed plate 5, sealing sleeve pipe 6, portable plate 7, packing 8, bolt 9 and water drain ball valve 10.Orifice tube 1 and connecting tube 4 are by seamless steel
Pipe is made, and fixed plate 5 is welded in connecting tube 4.When adjacent component is connected by flange, placing between ring flange can be high pressure resistant
Sealing gasket, to improve retention of excessive fluid pressure-bearing grade.
The centre bore and fixed plate 5 of the endoporus of the aperture ball valve 2 each ring flange coaxial with orifice tube 1 and portable plate 7
The aperture of drill bit via should be greater than the maximum gauge of drilling rod and drill bit, so that drilling rod and drill bit can be passed through.By adjusting
Section bolt 9 can change pressure of the annular boss of fixed plate 5 and portable plate 7 to packing 8, packing 8 is tightened up or is launched, packing
Thickness reduces during 8 expansion, inner space increase, and drill bit and drilling rod can be passed through just, thickness increase when tightening up, internal sky
Between reduce, can be compressed tightly against on drilling rod, prevent retention of excessive fluid from spraying.Therefore the structural parameters of packing 8 and its adjacent component are necessary
Depending on diameter according to drill bit and drilling rod.
Aqueous abundant, exist gushing water hidden danger underground mine give a farfetched interpretation injected hole when, bore in the position for needing drilling first
One shallow bore hole, shallow bore hole is inserted into having welded the orifice tube 1 of ring flange, then with high-pressure grout injector by cement, waterglass dual slurry
The gap that medium is injected between orifice tube 1 and the hole wall of shallow bore hole, makes orifice tube 1 be firmly combined together with country rock, then will be anti-
Other parts of spray apparatus are sequentially connected, you can drilled.
When boring injected hole, the bolt 9 of be connected plate 5 and portable plate 7 is in relaxed state, aperture ball valve 2 and the ball that discharges water
Valve 10 is in open mode, and the drill bit and drilling rod of rig sequentially pass through the drill bit via of portable plate 7, the sealing equipped with packing 8
Sleeve pipe 6, the drill bit via of fixed plate 5, connecting tube 4, T-shaped tee T 3, aperture ball valve 2 and orifice tube 1 are reached at country rock, to enclosing
Rock is drilled.
When drill bit touches water-bearing layer or tomography, retention of excessive fluid can instantaneously spray along injected hole, now progressively twist bolt 9
Tightly, while guaranteeing that drilling rod can be extracted, retention of excessive fluid is prevented to spray from drill rod sealing device, and the bottom of T-shaped tee T 3 is put
Water polo valve 10 is in opening, can play a part of drainage exhaust.The front end drill bit for treating drilling rod moves to T-shaped tee T 3
When interior, aperture ball valve 2 is progressively closed, thoroughly block retention of excessive fluid, follow-up slip casting work is then carried out again（Need to close during slip casting and discharge water
Ball valve 10）, eliminate gushing water hidden danger.
