In tunnel and slope engineering, the stock anchor technique is by wide application, the tradition adopts the entity stock, but cause the mortar to run off when extracting the slip casting pipe easily, the back improves the stock into the cavity design, make the stock realize the function of slip casting pipe, bond area for increasing stock and slip casting material is in order to improve anchor power, improve the stock of smooth outer wall for external screw thread structure more, for the relative movement who slows down the stock and the surrounding rock influence that brings for slip casting that warp, add the subassembly of strutting at the stock outer wall more, therefore, an anchor is effectual, the slip casting stock with low costs is urgent need.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a proclaim oneself hole slip casting stock fast accomplishes the hole sealing to the slip casting pore promptly through the in-process of the nut of screwing, slows down the relative movement of stock and the deformation of rock mass, reinforcing anchor effect.
Based on the problem, the utility model provides a technical scheme is a quick from hole sealing slip casting stock, including cavity stock, tray and nut, the stock outer wall is smooth, and the elasticity pipe is cup jointed to the stock outer end, and elasticity intraductal is fixed on the stock, the inboard welded connection pipe of tray, elasticity guan jue outer end and connecting pipe looks butt.
Wherein, the elastic tube is a rubber tube.
Wherein, the front end part of the elastic pipe is fixed with a hoop or bundled and fixed by a steel wire.
The outer end of the anchor rod is provided with a thread section, the nut is connected with the thread end in a screwing mode, and the outer end of the elastic pipe extends to the middle of the thread section.
Furthermore, the length of the overlapped part of the outer end of the elastic pipe and the thread section is 5-10 cm.
Wherein the length of the elastic tube is 1/4 of the length of the anchor rod.
The inner diameter of the connecting pipe is the same as that of the central hole of the tray, and the free end of the connecting pipe is abutted against the outer end of the elastic pipe.
Furthermore, the inner diameter of the connecting pipe is smaller than or equal to that of the elastic pipe, and the wall thickness of the connecting pipe is equal to or greater than that of the elastic pipe.
The utility model has the advantages and beneficial effect:
according to the grouting anchor rod, the elastic pipe is additionally arranged at the outer end part of the grouting anchor rod, the elastic pipe is pushed to expand and deform through screwing of the nut, the hole wall of the anchor rod hole is further extruded, the anchoring effect is enhanced, the relative movement of the anchor rod and the deformation of a rock body are slowed down, then grouting and hole sealing are smoothly performed, a push-pull assembly which additionally acts on the elastic pipe is omitted, the structure is simpler, and the manufacturing cost is low; the connecting pipe is fixedly connected to the inner side of the tray, so that the contact area between the tray and the elastic pipe is increased, the stress of the elastic pipe is guaranteed, and the anchoring effect is enhanced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the drawings, 1, an anchor rod; 2, a nut; 3. a tray; 4. a connecting pipe; 5. an elastic tube; 6. clamping a hoop; 7. a threaded segment.
Detailed Description
The following describes the embodiments of the present invention in detail with reference to the attached drawings.
As shown in fig. 1, a quick self-sealing hole grouting anchor rod comprises a hollow anchor rod 1, a tray 3 and a nut 2, wherein the outer wall of the anchor rod 1 is smooth, the anchor rod 1 is made of a four-quarter galvanized steel pipe, an anchor head is installed at the inner end of the anchor rod, the nut 2 is an M20 nut 2, an elastic pipe 5 is sleeved at the outer end of the anchor rod 1, the inner end of the elastic pipe 5 is fixed on the anchor rod 1, a connecting pipe 4 is welded in the center of the front side of the tray 3, and the outer end of the elastic pipe 5 is abutted to the connecting pipe 4.
Wherein, the elastic tube 5 chooses the rubber tube for use, the elastic tube 5 tip is tied up fixedly with the steel wire or is fixed with clamp 6, and preferred adopts clamp 6 to fix, keeps the one end of elastic tube 5 motionless, exerts thrust to it from one side.
The outer end of the anchor rod 1 is provided with a threaded section 7, the length of the threaded section 7 is 100cm, the nut 2 is connected with the threaded section 7 in a screwing mode, the outer end of the elastic tube 5 extends to the middle of the threaded section 7, further, the length of the part, overlapped with the threaded section 7, of the outer end of the elastic tube 5 is 5-10 cm, the fact that the tray 3 can be pushed to move and the elastic tube 5 can be expanded in a compression deformation mode in the process that the nut 2 is connected with the threaded section 7 in a screwing mode is guaranteed, and the fact that other push-pull components acting on the elastic tube 5 are added is omitted.
Wherein, the length of elastic tube 5 is 1/4 of stock 1 length, and outer end 1/4 length of stock 1 is the anchor section promptly, and elastic tube 5 is under the pressurized inflation deformation, further extrudees the pore wall in stock 1 hole, reinforcing anchor effect, slows down the relative movement of stock 1 and the deformation of rock mass.
