Abstract
A pipe sleeve type recoverable anchor rod is suitable for being used in rock engineering of mine tunnels, tunnels and the like, and comprises a rob body, a try and a nut which are arranged on the rob body, wherein a casing whose thickness and length can be regulated is arranged on the front end of the rod body, the top end of the casing is welded with a connector which is integrated with the rod body, and a screwing flat opening is arranged on the rod body. The pipe sleeve type can effectively provide support in the rock engineering of mine tunnels, tunnels and the like without using special devices, can be recovered by loosening the nut and rotating the rod through the screwing flat opening, the anchor rod has high strength, strong shear capability, excellent mechanical property, simple structure, convenient processing, strong versatility and wide applicability.
Description
Technical field
The utility model relates to a kind of anchor pole, is particularly useful for the pipe box formula recoverable anchor rod that uses in mine laneway, tunnel isolith geotechnique journey.
Background technology
Bolt support is one of mine laneway, the main support form of tunnel isolith geotechnique's journey, and it is wide that the application in underground construction becomes day by day.Present widely used anchor pole is disposable anchor pole still mostly, is difficult to recycle, and has caused great waste.The recoverable anchor rod of development mainly contains two kinds of forms both at home and abroad: a kind of is body of rod interconnection system, and it is formed by connecting by separable two sections bodies of rod, backs out not anchoring section of outer end during recovery; Another kind is plastic combined, and metallic rod body one end is provided with the plastics anchor head, and plastics anchor head and hole wall bonding during installation is separated the body of rod and plastics anchor head during recovery.These two kinds of recoverable anchor rods all can reduce the waste of resource to a certain extent, but also all there is its shortcoming separately, as: the recyclable segment length of body of rod interconnection system anchor pole is relevant with on-the-spot anchorage length, anchoring section length is long more, recyclable section short more, for satisfying the supporting intensity requirement, often adopts long anchorage length in the reality, make recyclable segment length very short, it is relatively poor to reclaim economic benefit; The plastic combined recoverable anchor rod complex structure is subjected to the influence of material, intensity a little less than, easily lost efficacy after the anchoring.Above shortcoming makes existing recoverable anchor rod can not get at the scene using widely.
The utility model content
Technical problem: the purpose of this utility model is the weak point that overcomes in the prior art, provide a kind of simple in structure, intensity is high, using later can the pipe box formula recoverable anchor rod that utilize once more for convenience detach.
Technical scheme: for realizing the purpose of this utility model, pipe box formula recoverable anchor rod of the present utility model comprises the body of rod, is located at pallet and nut on the body of rod, and lever front end is provided with a sleeve pipe, the top of sleeve pipe is welded with the connector that is connected as a single entity with the body of rod, and the body of rod is provided with twists flat mouthful; Described connector is threaded with the body of rod.
Beneficial effect: the utility model is simple in structure, easy to process, highly versatile can effectively provide supporting power not need to use special equipment in mine laneway, tunnel isolith geotechnique journey, construction and recovery are convenient, only need unclamp nut and can finish recovery operation by twisting the flat mouth rotation body of rod afterwards; And the intensity height of anchor pole own, shear resistance is strong, and mechanical property is good, has practicality widely.
Description of drawings
Fig. 1 is the utility model structural front view.
Among the figure: the 1-body of rod; The 2-connector; The 3-sleeve pipe; The 4-pallet; The 5-nut; 6-twists flat mouthful; Gap-7.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
As shown in the figure: it comprises the body of rod 1 pipe box formula recoverable anchor rod of the present utility model, is located at pallet 4 and nut 5 on the body of rod 1, and the body of rod 1 passes from the centre bore of pallet 4, matched in clearance; Nut 5 is screwed on the body of rod 1; The body of rod 1 front end is provided with sleeve pipe 3, the thickness and the length of sleeve pipe 3 are set according to actual needs, the length of sleeve pipe 3 is generally long than anchorage length, the top of sleeve pipe 3 is welded with the connector 2 that is connected as a single entity with the body of rod 1, connector 2 is threaded with the body of rod 1, leave gap 7 between the sleeve pipe 3 and the body of rod 1, the body of rod 1 is provided with twists flat mouthful 6.
During construction, at first in boring, push the anchoring agent, to twist the anchor pole that lumps together then and stretch into boring from connecting first end, and stir, by the anchoring agent connector 2 and outer tube 3 are bonded in the boring, at last add top tray 4 in the outer end of the body of rod 1, fastening nut 5 compresses pallet 4, forms axial force.
During recovery, unscrew nut 5 earlier, the body of rod 1 axial force is reduced to zero, tool using rotates the body of rod 1 by twisting flat mouthful 6 then, makes the body of rod 1 separate with connector 2, and the body of rod 1 is extracted out from outer tube 3 and got final product the most at last.
Claims (2)
1. pipe box formula recoverable anchor rod, comprise the body of rod (1), be located at pallet (4) and nut (5) on the body of rod (1), it is characterized in that: the described body of rod (1) front end is provided with a sleeve pipe (3), the top of sleeve pipe (3) is welded with the connector (2) that is connected as a single entity with the body of rod (1), and the body of rod (1) is provided with twists flat mouthful (6).
2. pipe box formula recoverable anchor rod according to claim 1 is characterized in that: described connector (2) is threaded with the body of rod (1).
