Description
Technical field
The utility model belongs to device for plugging, particularly relates to a kind of test boring device for plugging.
Background technology
Rubble class soil or broken formation drilling process in, because hole wall instability causes hole wall to collapse, even there is large tripe hole wall phenomenon.
Hole wall is collapsed and usually adopts the measure of grout pouring retaining wall, but when the cement paste of perfusion enters the hole on stratum, seam, hole in a large number before solidifying, cement paste causes shutoff failed by being diluted by the underground water of described ground intrastratal flow.In addition, when meeting karst strata in drilling process, because karst space is large or through, will a large amount of cement pastes be wasted or effective shutoff cannot be formed at all.Therefore, carry out probing at above-mentioned bad ground and there is insoluble Lost circulation problems and seriously restrict exploration progress, often cause the result of construction delay and waste resource.
The utility model ' bore blocking rolling device ' of notification number 201771466U discloses following technical scheme: be made up of reducing joint, basket, connect in basket lower end and roll joint, roll joint lower end and fix carbide alloy, carbide alloy sword diameter of going out is identical with basket external diameter, roll joint lower end and be provided with the mouth of a river, be provided with steel ball valve in the diminished shaft central hole rolling joint, diminished shaft central hole upper end is connected with valve hole, and lower end is fixed with gear rod.During leak stopping, to enter in boring under rolling device, when touching mixed clay ball (throwing in advance), steel ball valve moves draught excluder aperture of door, apply rolling pressure downwards, when pressure acquires a certain degree, rolling device is mentioned, steel ball valve departs from valve hole, is drawn into a small amount of flushing liquor, pressurizes after low speed revolution again.Leak stopping object is reached through repeatedly repeatedly rolling.
The plugging effect of above-mentioned utility model is unknown.
Summary of the invention
There is cement paste loss for existing bore blocking, cannot form the technical problem of effective shutoff in the utility model, and provides the test boring device for plugging that a kind of structure is simple, easy to operate, engineering cost is low.
The utility model takes following technical scheme for achieving the above object: this bore blocking device comprises drilling rod, feature is, drilling rod connects one and can insert boring and have the expanded rubber cover of closed bottom end, the length of described expanded rubber cover is corresponding with the complete hole wall of hole wall leak stopping place and top and the bottom thereof, the drilling rod being connected to expanded rubber cover is Grouting Pipe, expanded rubber cover inner chamber is cement paste Injection Space, and expanded rubber set upper side is distributed with overfolw hole.
The utility model can also take following technical measures:
The upper end of described expanded rubber cover is provided with the hickey be connected with drilling rod, is provided with to be connected and tiltedly takes between the main body that hickey and expanded rubber overlap, and connects tiltedly shoulder and is distributed with overfolw hole.
The main body of described expanded rubber cover is connected the upper end face connecting tiltedly shoulder and is provided with stirrup, is provided with the space holding cement paste between described stirrup and hole wall.
The inwall of described expanded rubber cover is provided with helical raised.
The beneficial effects of the utility model and advantage are: this bore blocking device adopts expanded rubber cover as main body, and the various performances of expanded rubber existing General Purpose Rubber goods, have again the performance of water-swellable, and the volume after immersion expansion is 2 ~ 3 times of original volume.The drilling rod that cement paste is threaded connection injects expanded rubber cover, expanded rubber is enclosed within while volume expansion increases and extrudes by cement paste, the cement paste that expanded rubber cover overfolw hole overflows will enter expanded rubber overlap and hole wall, between hole wall leak stopping place, the cement paste of final set is integrated making expanded rubber overlap to glued joint into borehole wall leak stopping place and the upper and lower complete hole wall of part of leak stopping place, forms the sealing blocking layer be made up of the cement paste solidified and rubber.Sealing plugged zone is not only applicable to the shutoff of the hole of borehole wall, seam, hole and karst strata, is applicable to hole wall yet and collapses the large tripe hole wall that occurs and form pregnant artificial hole wall.The utility model has the advantages that structure is simple, easy to operate, engineering cost is low, is especially specially adapted to the outstanding advantages of the serious thief zones such as rubble class soil, karst.
Accompanying drawing explanation
Accompanying drawing 1 is that this bore blocking device example structure partly cuts open schematic diagram.
Accompanying drawing 2 is Fig. 1 embodiment using state generalized sections.
Mark in figure: 1 drilling rod, 2 expanded rubber covers, 2-1 hickey, 2-2 connects tiltedly shoulder, 2-3 overfolw hole, 2-4 helical raised, 3 stirrups, 4 cement pastes, 5 hole walls, and 6 cave in hole wall.
Detailed description of the invention
The utility model is further illustrated below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in Figure 1, the hickey 2-1 that drilling rod 1 lower end and expanded rubber overlap 2 upper ends is threaded, the bottom end closure of expanded rubber cover 2 and can insert boring, hickey and expanded rubber overlaps to be provided with to be connected between the main body of 2 tiltedly takes on 2-2, connects tiltedly to take on to be distributed with overfolw hole 2-3.
The length of expanded rubber cover 1 is corresponding with the complete hole wall of hole wall leak stopping place and top and the bottom thereof, and actual product technical data should many specifications, to meet the actual needs of the common hole of different geological condition, seam, hole and hole wall collapse situation.
The drilling rod 1 being connected to expanded rubber cover 2 is Grouting Pipe, and it is cement paste Injection Spaces that expanded rubber overlaps 2 inner chambers, and the inwall of expanded rubber cover 2 is provided with helical raised 2-4, and helical raised is conducive to the adhesive strength that the cement paste of final set and expanded rubber overlap 2.
Expanded rubber cover 2 its main body upper end faces are provided with stirrup 3, the space holding cement paste is provided with between stirrup 3 and hole wall 5, cement paste in this space is from overfolw hole 2-3, and the cement paste after final set makes stirrup 3 reliably bonding with hole wall 5, is conducive to the resistance to overturning in expanded rubber cover 2 use.
As shown in Figure 2, this device is used when there is hole wall collapse in drilling process, using method to continue to creep into lower stabilizer stratum about 0.5 meter, carry out reaming with the reaming bit of one-level larger than boring aperture, by drilling rod 1, expanded rubber being overlapped 2 after reaming completes gos deep at the bottom of drilling hole, 2 slip castings are overlapped by drilling rod 1 pair of expanded rubber, the cement paste that overfolw hole 2-3 overflows will enter between stirrup 3 and hole wall 5, expanded rubber overlaps 2 and hole wall 5 and caving between hole wall 6 or other hole wall leak stopping place, and mobility, the time of setting of cement paste determine according to on-site actual situations.Cement paste is configured by cement, water and water glass and forms, by additive control cement paste final setting time.Expanded rubber cover 2 is closely cemented to the hole wall 5 of non-leak stopping section and the hole wall 6 that caves in and is integrated under himself expansion and cement paste 4 squeezing action, and makes expanded rubber cover 2 and cement paste final set form pregnant artificial hole wall.Because the hickey volume expansion of expanded rubber cover departs from drilling rod voluntarily after having poured into.After expanded rubber cover is bonded to entirety with hole wall, carry out cleaning bottom of hole by the drill bit in foramen primum footpath continue to creep into.If bridging plug can be used to support when being non-good ground bottom expanded rubber cover 2.
