Abstract
The utility model provides a large deformation stock is consolidated in slip casting, the stock is docked in proper order through the sleeve pipe along length direction by two sections at least bodies of rod and forms, all slides and set up in the cover intraductally in the adjacent just right both ends of two sections bodies of rod, and all be provided with between the tip of two sections bodies of rod and the sleeve pipe and be used for hindering the body of rod towards the outside gliding damping portion of orientation of sheathed tube, the outside cover of stock one end is equipped with and is used for preventing that the thick liquid from overflowing ending of stock fixed orifices and starching the stopper, and the outside of ending the thick liquid stopper compresses tightly and is provided with only thick liquid stopper fixed part. Receive great tensile stress and drawn badly easily in the tunnel of deep in order to solve current stock, and let and press large deformation stock material cost high, the use of unsuitable large tracts of land, though and current letting press the large deformation stock to play certain effect, the main factor problem of breaking or lead to finally strutting the failure of stock. The utility model belongs to mining area rock mass reinforcing field.
Description
Technical field
This utility model relates to a kind of grouting and reinforcing anchor pole, belongs to rock mass reinforcing field.
Background technology
At present, along with the mining degree of depth is continuously increased, pressure from surrounding rock the most constantly increases, soft rock mass and high-ground stress in the face of deep, currently known anchor pole is easily drawn bad by bigger tension in deep tunnel, and when rock crushing degree is higher, the anchorage effect of anchor pole the most easily lost efficacy.Based on problems, spy improves and expects and can play a role in actual production.
But, more existing allowing presses large deformation anchor rod to there is also some problems, mainly shows themselves in that
(1) can large deformation material cost higher, be not suitable for large-area use, still have cost to be reduced in the face of universal deep mining problem；
(2) design unsatisfactory, although serve certain effect, but anchor pole break the main factor still resulting in final supporting failure.
Summary of the invention
The purpose of this utility model is: provide a kind of grouting and reinforcing large deformation anchor rod, easily drawn bad by bigger tension with the existing anchor pole of solution in deep tunnel, and make pressure large deformation anchor rod material cost high, be not suitable for large-area use, although and existing allow pressure large deformation anchor rod serve certain effect, but anchor pole break the main factor problem still resulting in final supporting failure.
Scheme of the present utility model is as follows: a kind of grouting and reinforcing large deformation anchor rod, described anchor pole is docked successively by sleeve pipe along its length by least two sections of bodies of rod and forms, adjacent two sections of bodies of rod just to two ends be all slideably positioned in sleeve pipe, and between the end of two sections of bodies of rod and sleeve pipe, it is provided with the damper portion for hindering the body of rod outside direction slip towards sleeve pipe, the outer sheath of described anchor pole one end is provided with for preventing serosity from overflowing the stop grouting plug of anchor pole fixing hole, and the outer side compression of stop grouting plug is provided with stop grouting plug fixed part.
Described stop grouting plug fixed part includes the backing plate screwing the nut being sheathed on anchor pole and being arranged between nut and stop grouting plug, by tightening nut, stop grouting plug is compressed by backing plate.
One end of described anchor pole is provided with anchor head, and the other end is provided with stifled slurry plug, offers slurry-feeding hole along its length, the sidewall of the body of rod offers the slurry outlet being connected with slurry-feeding hole in anchor pole in the body of rod；
Described damper portion is the damping material being filled between the end of the body of rod and sleeve pipe, and the first pretightning force that the resistance of damper portion is axially subject to more than the body of rod；
The method utilizing above-mentioned bolt anchorage rock mass, including:
Anchor pole importing the step within rock mass: when anchor pole imports rock mass inside, anchor head is bonded in internal rock mass by powder stick；
By anchor pole step of reperfusion serosity in rock mass: tightening nut, backing plate is made to be compacted to by stop grouting plug between opening part and the anchor pole of anchor pole entrance hole, prevent serosity from overflowing, by the slurry-feeding hole of anchor pole one end and slurry outlet reperfusion serosity in rock mass of being connected with slurry-feeding hole, along with the solidification of serosity, anchor pole forms an entirety with rock mass；
Under external force, when rock mass occurs STRESS VARIATION once again, anchor pole is by extra tension, and now the body of rod of inside pipe casing is owing to pulling force is more than the resistance of damper portion, the body of rod is to slide outside, the partial-length of the body of rod is released, and the stress of rock mass is released, during this, damper portion is constantly compressed, the resistance of the body of rod is gradually increased by damper portion, and then body of rod tension reaches balance again with the resistance of damper portion, and rock mass reaches stable again.
This utility model is compared with prior art, major advantage is: under external force, when there is bigger STRESS VARIATION in rock mass, this anchor pole can extended length, the stress making rock mass is released and again consolidates, and this process is less to the damage of anchor pole, improve the service life of anchor pole, while consolidating crack stability, bear the deformation of roadway surrounding rock greatly, and simple in construction, additionally, owing to this material quality of bolt is common, support cost can be significantly saved for the new material of other large deformation, while Quadratic Stability rock mass, it also is able to save the usage amount of anchor pole.
