Description
Technical field
The utility model relates to a kind of drilling water burst plugging devices, and in particular to a kind of advance borehole is visited in Hydraulic Projects to height
Press the fast plugging device of big water yield drilling, the borehole sealing big particularly suitable for water yield, hydraulic pressure is high is reinforced and sharp again
With.
Background technique
In tunnel and shaft sinking construction, when especially by complicated water-bearing zone, it is necessary to it carries out advance borehole and visits water, thus
To evade water bursting disaster.It, can be by the way of cement-water glass double grouting when water exploring drill hole hydraulic pressure is small, water yield is few
It is blocked, but when water yield is big, hydraulic pressure is high, cement-water glass double grouting material can generate that slurries are discrete and slurry knot
Structure hole problem.In practice, there are also grouted anchor bar is wrapped with linen thread directly to pound into water exploring drill hole, such method not only blocks engineering
It is not firm, and it is also highly difficult to construct.Therefore, water yield is big, hydraulic pressure is high advance borehole quickly, efficiently block be one urgently
The technical problem of solution.
Summary of the invention
The purpose of this utility model is not firm aiming at closure of the existing technology, construction is highly difficult and can not accomplish
Quickly, the problem of efficiently blocking, and a kind of fast plugging device for high pressure water burst drill is provided.
For the above-mentioned purpose for realizing the utility model, a kind of quick blocking for high pressure water burst drill of the utility model is filled
It sets and is implemented with the following technical solutions:
A kind of fast plugging device for high pressure water burst drill of the utility model, is mounted in high pressure water burst drill, it
It is to be combined and constituted by grouted anchor bar, anchor pole bagging, bagging grouting pipe, is equipped with grouted anchor bar valve on the top of grouted anchor bar,
It is equipped with bagging grouting pipe valve on bagging grouting pipe top, anchor pole protrusion, anchor pole bagging set are machined on grouted anchor bar
It is fixed on grouted anchor bar and with bagging retainer plate, bagging grouting pipe is inserted into anchor pole bagging, the sack of anchor pole bagging
Keep sealing.
Corresponding position of the anchor sleeve bag for packing fruits on the grouted anchor bar for being machined with anchor pole protrusion is preferred, to increase it
Between binding force.
The diameter of the grouted anchor bar is 20-30mm smaller than the aperture of high pressure water burst drill, such as the water gushing out with high pressure of φ 42mm
Drilling, grouted anchor bar select φ 20-30mm；The diameter of φ 90mm high pressure water burst drill, grouted anchor bar selects φ 70-80mm；It is right
The high pressure water burst drill being relatively large in diameter, grouted anchor bar diameter range of choice is larger, can suitably reduce grouted anchor bar diameter.It is described
Anchor pole bagging use and be preferred using polyester water strainer bagging, polyester water strainer is industrial water strainer, is had good permeable, saturating
Gas property, air permeability (127PA) >=4000, but since processing technology is special, injecting paste material can be prevented to penetrate.Moreover, poly-
The type kind of ester water strainer is more, and wire side intensity is differed from >=700N/CM to >=1500N/CM, and joint strength is from >=450N/
CM to >=1000N/CM is differed, and the bagging for selecting suitable polyester water strainer to be processed into can satisfy the slip casting of such water burst drilling holes
Plugging strength requirement.The diameter of anchor pole bagging is 1.1-1.5 times of high pressure water burst drill aperture.
It is buckled in the lower part of grouted anchor bar equipped with grouted anchor bar.
In practical applications, with drilling tool on the hole wall of high pressure water burst drill construction drill hole wall groove, will be assembled
Fast plugging device is fixed in high pressure water burst drill, is carried out slip casting into anchor pole bagging from bagging grouting pipe, is set when reaching
When constant-pressure, stop slip casting, keeps grouted anchor bar valve opening state, it, will after injecting paste material solidification-stable in anchor pole bagging
Grouted anchor bar valve is closed, to complete the closure of high pressure water burst drill.
High pressure is reinforced if you need to further slip casting rich in water layer, the grouting for water blocking reinforcing such as in shaft sinking face can be with
Grouting pump is connected to the grouted anchor bar valve being arranged on grouted anchor bar, further high pressure water burst drill is carried out using grouted anchor bar
Grouting and reinforcing, closure, but grouting pressure should be fully considered in the design phase.
Also there is mine that the water in high pressure water burst drill is used for industrial water, to improve mine benefit.In this case,
The grouted anchor bar valve being arranged on grouted anchor bar is opened, the water export in high pressure water burst drill is used for industrial process waters.Such as
In tunnelling, after the boring water seal of single-point in tunnel being blocked up, water is used for drilling for tunnel working face.
A kind of fast plugging device for high pressure water burst drill of the utility model after the above technical solution is adopted, have with
It is lower the utility model has the advantages that
(1) high pressure water burst drill is divided into two parts and blocked by the utility model, and a part is the slip casting anchor for adding valve
Bar, interval of the another part between grouted anchor bar and high pressure water burst drill.Mode is blocked using two steps, first from bagging slip casting
Conduit carries out slip casting into anchor pole bagging, carries out slip casting closure to the interval between grouted anchor bar and high pressure water burst drill, at this time
Hollow grouted anchor bar carries out hydrophobic pressure release, and after slurry solidification-stable, the valve on grouted anchor bar is closed, i.e. completion high pressure
The closure work of water burst drilling holes.Come blocking high-pressure water-bearing layer if you need to further slip casting, grouting pump can be connected to the valve of grouted anchor bar
Door, so as to carry out grouting process.
(2) the utility model safe and efficient, easily can block high pressure rich in water drilling hole, greatly change
The plugging technology of traditional such drilling, reduces the time that slip casting worker is exposed to underground high humidity working environment, and reduction is got over
Therefore a possibility that occurring.
(3) borehole sealing is combined with mine engineering is practical, is especially combined with further work after borehole sealing,
The energy conservation in mine may be implemented.
(4) anchor force can be adjusted according to different geological conditions, there is the practical adaptability of good engineering.
(5) water of high pressure water burst drill can also be comprehensively utilized, is used for industrial production.
