Description
Technical field
The utility model relates to the underground such as mine engineering, construction of tunnel geotechnical engineering, is particularly useful for the anchoring support of the breakable unstable coal rock tunnel of top board.
Background technology
Along with the development of the underground geotechnical engineerings such as China's mine engineering, construction of tunnel, bolt support technology has been widely used, is to realize one of safety, highly efficient and productive key technology.But due to the continuous increase of mining depth, and geological conditions becomes increasingly complex, deep laneway surrounding rock deflection is comparatively large, and roadway surrounding rock destroys serious, and current common anchor pole cannot meet supporting needs.
At present, deep crush roadway surrounding rock supporting mainly adopts slip casting anchor stock and extension type anchor pole.Slip casting anchor stock to country rock reperfusion serosity, makes fragmented rock body be cemented to entirety by the vestibule of hollow lever, improves Surrounding Rock Strength and from load; But for some top boards easily broken or unstable roadway surrounding rock that deflection is larger, slip casting anchor stock deformable amount is less, very easily damages.Although extension type anchor pole has certain deflection, generally adopt resin anchoring agent, this anchorage style often forms area of stress concentration in anchored end, anchored end surrounding rock body is destroyed, causes fastening invalidation.Current anchor pole all cannot meet requirement of engineering when unstable surrounding rock breakable in the face of top board, not only affects roadway construction, and likely cause underground construction unstable failure when rock deformation is great time, threaten the life security of workman.
Chinese patent 201110368805.8 discloses a kind of continuous resistance-increasing deforming anchor cable, it is combined with friction sleeve pipe by contractibility component, when country rock generation large deformation, tension is extended and does not destroy, but its anchorage style is termination formula anchoring, easily cause anchored end stress to concentrate, make fastening invalidation.Chinese patent 201410030080.5 discloses a kind of multistage anchoring type resin anchor, and it is by repeatedly anchoring, dispersion load, but its deflection is less, cannot adapt to the present situation of current deep wall rock large deformation.
Summary of the invention
For the Relational Questions mentioned in background technology, the utility model provides a kind of scalable internal-injection type secondary anchoring type anchor pole, this anchor pole can coordinate anchor net to use, tension to extend and itself does not destroy when roadway surrounding rock generation large deformation, and can according to the concrete deformation characteristics of country rock, segmentation anchoring---originally carry out termination formula anchoring with resin anchoring agent, when anchor pole Tensile grows to the limit, carry out slip casting anchoring, avoid anchored end to form area of stress concentration, ensure production safety.
To achieve these goals, the utility model adopts technical scheme:
Scalable internal-injection type secondary anchoring type anchor pole, anchor rod main body is made of metal, and is divided into anchor rear, telescopic section, slip casting section, anchor head section four part.Anchor rear has non retern valve, locking nut, pallet to form; Telescopic section is by friction sleeve pipe and form with the hollow type anchor bar body of vestibule, and be socketed on by anchor bar body in friction sleeve pipe, centre adds shock mount; Slip casting section is hollow type anchor bar body, and its surface is provided with vestibule can to country rock reperfusion serosity; Anchor head section is termination formula anchoring, carries out anchoring by resin explosive roll.
Above-mentioned non retern valve is ball valve, inner hollow, can prevent slurries from pouring in down a chimney by the folding of switch.
Above-mentioned friction sleeve pipe is made of metal, and inner hollow, one end is inwardly shunk in end.
Above-mentioned hollow bolt body is made of metal equally, inner hollow, and the body of rod has every 100mm the vestibule that a diameter is 8mm.The length of anchor bar body and friction sleeve pipe can select different size to combine according to scene is actual.Concrete size as shown in Figure 2.
Above-mentioned termination formula anchoring adopts resin explosive roll to realize, and also can adopt novel expansiveness material.
Beneficial effect: the utility model structure is simple, easy for installation, has slip casting and allows pressure dual-use function.Country rock tunnel occur large deformation time can tension extend and itself does not destroy; Before enforcement slip casting, carry out anchoring with resin explosive roll, anchor pole is had in advance higher anchored force; Grouting with plunger can delayedly be carried out, and energy reinforced roadway country rock, improves the bulk strength of breaking roof, increase the bearing capacity of country rock self.If rock deformation is less, when top board is not broken or degree of crushing is lighter, also can not carries out injecting treatment, determine according to on-site actual situations.Not only maintain the stable of top board, and ensure that safety in production.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described:
The scalable internal-injection type secondary anchoring type anchor pole that the utility model provides, is divided into anchor rear, telescopic section, slip casting section, anchor head section four part.Anchor rear has non retern valve 2, locking nut 3, pallet 4 to form; Telescopic section is by friction sleeve pipe 6 and form with the hollow type anchor bar body 8 of vestibule, and be socketed on by anchor bar body in friction sleeve pipe, centre adds shock mount 7, and it is all made of metal, and has extremely strong tension and shear resistance; Slip casting section is hollow type anchor bar body 8, and being provided with vestibule can to country rock reperfusion serosity; Anchor head section is termination formula anchoring, carries out anchoring by resin explosive roll 11, and the length of resin explosive roll, diameter and quantity are chosen according to reality boring; The resin anchoring agent that resin explosive roll 11 wraps up for plastic packaging film, the length of resin explosive roll, diameter and quantity are chosen according to boring.Between anchor head section and slip casting section, add resin explosive roll cushion block 10, it is made up of macromolecular material, and effect prevents Anchor Agent from blocking extravasating hole; At the additional topping of resin explosive roll cushion block 10, topping is abrasion-resistant material.
During use, first choose the actual anchor bar body matched and the sleeve pipe that rubs with engineering, anchor bar body is socketed in friction sleeve pipe.Then resin explosive roll is put into boring, inserted by the anchor pole assembled, make resin explosive roll fragmentation that chemical reaction occur and be fixed in boring by anchor pole head, then upper padding plate and nut, applies a small amount of pretightning force and screws, so far, and installation.When country rock deforms, the flexible stressed stretching of the body of rod, makes spring-compressed, until reach maximum resistance.Now, can, by extravasating hole to country rock reperfusion serosity, make loose rock mass be cemented to entirety, improve Surrounding Rock Strength and from load, increase the service life in tunnel.If rock deformation is less, when top board is not broken or degree of crushing is lighter, also can not carries out injecting treatment, determine according to on-site actual situations.
