Abstract
The utility model discloses an expansion prestressed anchor rod, belonging to the technical field of the anchor rod for protecting the roof, bottom board, or the shaft lining. The anchor rod solves the problems of the prior art, such as long geotechnical engineering construction time, complicated construction craft, high cost and easy slip. The utility model is characterized in that each end of the anchor rod is provided with nuts, an expanding cone and a steel pipe are sheathed at the anchor rod between the nuts, the post face of the steel tube is provided with a plurality of slurry seepage holes, one end post face of the steel tube is welded with a perfusing spout. The utility model is an anchor rod with a mechanical self-locking anchoring device, so the anchor rod can be used in the field for anchoring the dehiscence, instability, slip, slump, connection, etc. of the rock mass, the earth body, buildings, and earth work means.
Description
A kind of expansion prestressed anchor belongs to top board, base plate or lining shaft protection and uses the anchor pole field.
Earthwork engineering to the cracking of rock mass, the soil body, building, geotechnological member, unstability, slippage, the existing anchoring that caves in, connect in, because the object difference of anchoring construction, employed anchoring is also different, but all there is following defective jointly in they: (1) uses grouting pre-press equipment, grouting conduit to cause construction technology complexity, cost height; (2) to wait for after slurry reaches certain intensity and just can finish anchoring that the anchoring duration is longer to making after the grouting; (3) use the perfusion mortar anchoring, slip easily.
The purpose of this utility model is to design a kind of grouting pre-press equipment that do not use, special-purpose grouting conduit, and anchoring process is simple, and cost is lower, uses the anchoring of mechanical self-latching type anchor device fast and the novel anchor rod of not slip.
The utility model is design like this: it is made up of anchor pole, nut, expansion cone, steel pipe, anchor pole adopts a garden steel, having attacked screw thread at the two ends of garden steel makes, nut is equipped with at the two ends of anchor pole, on the anchor pole between the nut, be equipped with expansion cone and steel pipe, have several slurry seepage holes on the cylinder of steel pipe, be welded with filling nozzle on newel post's face of steel pipe, the other end has several dilatation joints.
The advantage of expansion prestressed anchor is: can not use the precompressed grouting equipment by quick anchoring generally speaking, in particular cases use its equipment and the conduit that need not be in the milk, technology is simple, construction cost is low; Because of using the utility model anchoring time short, improved work efficiency; The anchorage reliability height does not need the anti-test selective examination anchoring quality of dialling.
Fig. 1 is a front view of the present utility model
The utility model is achieved in that it is made up of anchor pole (1), nut (2), expansion cone (3), steel pipe (4), filling nozzle (6), dilatation joint (7).Attacked screw thread on the two ends of anchor pole (1), the tapering of expansion cone (3) is 1/10, has a plurality of slurry seepages holes (5) on the cylinder of steel pipe (4), has two holes symmetrically on newel post's face of steel pipe (4), and slurry filling nozzle (6) weldering thereon.The other end has several dilatation joints (7), and expansion cone (3) and steel pipe (4) are enclosed within on the anchor pole (1), and the two ends that two nuts (2) are contained in anchor pole (1) respectively make it constitute an integral body.
Claims (1)
1, the stress anchor pole is given in a kind of expansion, form by anchor metal, nut, expansion cone, steel pipe, nut is equipped with at the two ends that it is characterized in that anchor pole, anchor pole place between nut is with expansion cone and steel pipe, have several slurry seepage holes on the cylinder of steel pipe, on one newel post's face of steel pipe filling nozzle is housed, the other end has several dilatation joints.
