Abstract
The utility model relates to a pipe seam type deformation anchor rod comprising a rod body, an expansion core, a cushion plate and a nut, and improving an existing pipe seam type deformation anchor rod. A rod body is a corrugated pipe rod body provided with a belt longitudinal seam. The front end of the anchor rod is provided with the expansion core and the rear end of the anchor rod is provided with the nut and the cushion plate. The anchor rod can achieve top end anchoring and remarkably enhances anchoring force. Simultaneously, when surrounding rocks are immensely deformed, the corrugated rod body can automatically spread and extend, and can absorb deformation energy of the surrounding rocks during a deformation process. In addition, the tail end of the anchor rod is stable by using the nut to replace a pulling ring. The anchor rod is low in manufacture cost, remarkably improves anchoring effect, and has high economic benefits.
Description
Technical field
The utility model relates to a kind of geotechnical engineering supporting field, particularly relates to a kind of pipe seam formula distortion anchor pole, is a kind of improvement to existing pipe-seam type anchor rod.
Background technology
Pipe-seam type anchor rod is known.Pipe-seam type anchor rod is the anchor pole of a kind of full length fastening, active reinforce adjoining rock, mainly is applicable to temporary lining or the permanent support of the well lanes engineering such as mine metallurgy, water power, railway.Its three-dimensional part is that employing high duty metal coiled sheet is pressed into the tubulose body of rod with longitudinal joint, and tail end is welded with draw ring, supports the use with supporting plate.When it is installed on than the slightly little boring of caliber, can in length range, apply radial pressure and produce the frictional force that stops country rock to glide hole wall immediately, add the supporting force of anchor rod pallet board supporting plate, thereby make country rock be in triaxial stress state, realizing because the friction anchoring power that tube wall elasticity tension force extruding hole wall produces, is that initiatively back-up coat is got a haircut and educated self anchoring bolt of country rock.In the situations such as blasting vibration country rock anchor moves, the later stage anchored force is significantly increased, and when remarkable displacement occured country rock, anchor pole did not lose its supporting drag.
This known pipe-seam type anchor rod, its major defect has: (1) anchored force is lower, it is little to be mainly manifested in the top anchored force, anchor pole and bore diameter aperture ratio do not mate, install not in placely etc., the draw ring of (2) tail end welding is because the welding quality problem, install and use procedure in come off easily, thereby cause the generation of contingency; (3) can't suitable for surrounding rock to the large deformation of roadway convergence, the situation that anchor pole is broken in the centre appears.
This shows that above-mentioned existing pipe-seam type anchor rod obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.Therefore how to found a kind of a kind of pipe seam formula distortion anchor pole of new structure, also becoming the current industry utmost point needs improved target.
Because the defective that above-mentioned existing pipe-seam type anchor rod exists, the present utility model people is based on being engaged in for many years abundant practical experience and professional knowledge of this type of product design manufacturing, and the utilization of cooperation scientific principle, positive research and innovation in addition, in the hope of founding a kind of a kind of pipe seam formula distortion anchor pole of new structure, can improve general existing pipe-seam type anchor rod, make it have more practicality.Through constantly research, design, and through after repeatedly studying sample and improvement, finally create the utility model that has practical value.
Summary of the invention
The purpose of this utility model is, overcome the defective that existing pipe-seam type anchor rod exists, and a kind of pipe seam formula that a kind of new structure is provided is out of shape anchor pole, technical problem to be solved is to make it make the high-strength metal sheet of the pipe seam formula distortion anchor pole tubulose body of rod, is processed into corrugated via special process.In country rock large deformation situation, the corrugated body of rod can extend by Automatic-expanding, can absorb the deformation energy of country rock simultaneously in deformation process.The anchor pole front end is equipped with expanded core, and inside is provided with pawl.Behind the rockbolt installation, use the jacking of jacking instrument, the expanded core front end opens, thereby the anchoring that realizes the anchor pole front end is corrugated because of the anchor pole tube wall, but the end of anchor rod mounting nuts.During installation, anchor pole is squeezed into ground inside, and after the front end anchoring, backing plate is close to crag, and nut tightening can prevent effectively that supporting plate is loosening and come off from the body of rod.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of pipe seam formula distortion anchor pole that the utility model proposes, comprising: the body of rod, expanded core, backing plate, nut; Described this body of rod is the undulatory tubulose body of rod that has with longitudinal joint, and described anchor pole front end is provided with expanded core, and described rear end is provided with nut and backing plate.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Aforesaid a kind of pipe seam formula distortion anchor pole, the expanded core quantity of wherein said anchor pole front end can be one or more.
Aforesaid a kind of pipe seam formula distortion anchor pole, wherein said end of anchor rod is fixed by nut.
Aforesaid a kind of pipe seam formula distortion anchor pole, wherein said end of anchor rod nut shape is hexagon or hemispherical.
The utility model compared with prior art has obvious advantage and beneficial effect.As known from the above, for achieving the above object, the utility model provides a kind of pipe seam formula distortion anchor pole, comprising: the body of rod, expanded core, backing plate, nut; Described this body of rod is the undulatory tubulose body of rod that has with longitudinal joint, and described anchor pole front end is provided with expanded core, described rear end mounting nuts and backing plate.Make the high-strength metal sheet of the pipe seam formula distortion anchor pole tubulose body of rod, in country rock large deformation situation, the corrugated body of rod can extend by Automatic-expanding, can absorb the deformation energy of country rock simultaneously in deformation process.The anchor pole front end is equipped with expanded core, and inside is provided with pawl.Behind the rockbolt installation, use the jacking of jacking instrument, the expanded core front end opens, thereby realizes the anchoring of anchor pole front end.Because the anchor pole tube wall is corrugated, but the end of anchor rod mounting nuts.During installation, anchor pole is squeezed into ground inside, and after the front end anchoring, backing plate is close to crag, and nut tightening can prevent effectively that supporting plate is loosening and come off from the body of rod.
By technique scheme, a kind of pipe seam formula distortion of the utility model anchor pole has following advantages and beneficial effect at least:
1, makes the high-strength metal sheet of the pipe seam formula distortion anchor pole tubulose body of rod, be processed into corrugated via special process.In country rock large deformation situation, the corrugated body of rod can extend by Automatic-expanding, can absorb the deformation energy of country rock simultaneously in deformation process.
2, the anchor pole front end is equipped with expanded core, and inside is provided with pawl.Behind the rockbolt installation, use the jacking of jacking instrument, the expanded core front end opens, thereby realizes the anchoring of anchor pole front end
3, because the anchor pole tube wall is corrugated, but the end of anchor rod mounting nuts.During installation, anchor pole is squeezed into ground inside, and after the front end anchoring, backing plate is close to crag, and nut tightening can prevent effectively that supporting plate is loosening and come off from the body of rod.
