Description
Technical field
The utility model belongs to coal mine drilling aggregate adding technique field, and in particular to one kind drilling injection aggregate addition dress
Put.
Background technology
Coal mine water damage is to be only second to the mine disaster type of gas explosion, and seam mining was gradually by upper group of coal in recent years
Be transferred to deep the following group coal, Carboniferous System the following group coal apart from bottom plate Carboniferous System limestone aquifer, Ordovician system artesian aquifer interlamellar spacing compared with
Closely, fault tectonic, which destroys, easily causes water gush face, in order to accelerate governance efficiency during water gush face grouting treatment, carries
High grouting for water blocking effect, the closure in water inrush channel and water outlet crack need to be carried out using aggregate.
In injection aggregate adding set before use, normal grouting for water blocking, transformation water-bearing layer or the operation of plugging structure crack
In, it is the aggregate by the way that needs are added（Saw foam, sea-tangle, soya bean etc.）It is machined to the particle diameter that slush pump water suction halter can suck
（Particle diameter 2-3 millimeters）, aggregate is used into artificial puddling in cement grout, by slush pump by passing through note after the halter suction that absorbs water
Starch in pressure duct injection hole.
Not only limitation is big but also waste is a large amount of artificial for traditional aggregate addition pattern, and drawback is more；Firstth, aggregate is added
Amount very little, it is also necessary to largely manually strictly processed in advance.Second, because aggregate size is small, closure crack effect is poor,
It is serious to waste cement grout, slowly effect.3rd, the aggregate that can be added is single, the aggregate broken for that can not carry out particle diameter, close
Spending big aggregate can not be added.This is the deficiencies in the prior art part.
Therefore, for drawbacks described above of the prior art, there is provided a kind of drilling injection aggregate adding set of design, to solve
Above-mentioned technical problem, it is necessary.
Utility model content
The purpose of this utility model is, in view of the above-mentioned drawbacks of the prior art, providing design a kind of drilling injection
Aggregate adding set, to solve above-mentioned technical problem.
To achieve the above object, the utility model provides following technical scheme：
One kind drilling injection aggregate adding set, it includes water blockoff inlet well pipe, and one end of water blockoff inlet well pipe is deep
Entering in water blockoff inlet well, it is characterised in that the other end of water blockoff inlet well pipe is connected with intermediate casing by ring flange, in
Between sleeve pipe connection have a slip casting sleeve pipe, one end that slip casting sleeve pipe is connected with intermediate casing is provided with ring flange, slip casting sleeve pipe with it is middle
Connected between sleeve pipe by ring flange, the other end of slip casting sleeve pipe is provided with end cap, and snap joint, fast quick access are welded with end cap
Head connection grouting pipeline, grouting pipeline are connected with slip casting machine, and end cap is threadedly engaged with slip casting sleeve pipe；Slip casting sleeve pipe
Relief valve is being provided with below intermediate casing side, drilling gate valve is provided with intermediate casing.
Preferably, described slip casting sleeve pipe is stainless steel sleeve pipe.
Preferably, described slip casting bushing outer surface is provided with skid resistant course.
Preferably, described skid resistant course is the bulge-structure for being arranged on slip casting bushing outer surface.
The beneficial effects of the utility model are, widen grouting for water blocking addition aggregate species, by sawing foam, soya bean etc. originally
Adding sponge, cloth waste, peanut, sandstone etc., all can enter in conduit pipe and water outlet crack, can play water plugging effect
Various materials；Increasing particle size, reduces the manufacturing procedure to aggregate, and addition efficiency greatly improves.Solve aggregate addition starching
The blocking of pulp absorbing pump halter, the situation that grouting pipeline blocks are easily caused in liquid, while is decreased to grouting equipment（Slip casting machine）'s
Abrasion.
The aggregate addition of different-grain diameter, unlike material, improves grouting for water blocking effect, reduces the waste of cement grout,
Reduce projective water point water yield, greatly improve grouting for water blocking efficiency.In addition, the utility model design principle is reliable, structure letter
It is single, there is very extensive application prospect.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
