Abstract
The utility model discloses an anchor rod with the end portions capable of being expanded, and belongs to the field of anchor rods. The anchor rod with the end portions capable of being expanded comprises an actuating system and a reaming system, wherein the actuating system comprises a traction cable, an inner sleeve and an outer sleeve sleeved outside the inner sleeve, a flange disk in which a traction cable pore passage is formed is arranged at the upper end of the inner sleeve, and the lower end of the inner sleeve, the upper end of the outer sleeve and the lower end of the outer sleeve are provided with connecting hinges which are the same in number; the traction cable penetrates through the traction cable pore passage of the flange disk at the upper end of the inner sleeve to be connected with the upper end of the outer sleeve through the connecting hinge at the upper end of the outer sleeve; the reaming system comprises reamers and guide rods, the number of the guide rods is at least three, the guide rods are evenly distributed and installed on the peripheral wall of the lower end of the outer sleeve, the reamers corresponding to the guide rods are installed on the inner circumferential wall of the lower end of the inner sleeve, and the lower ends of the guide rods are connected to the midpoint positions of the reamers through pin hinges. The anchor rod with the end portions capable of being expanded has the advantages that the ends of the anchor rod can be expanded and penetrate into the rock and soil body, anchoring force is increased, pulling resistance of the anchor rod is enhanced, loss of the following anchoring force is small, and following maintenance expenses are reduced.
Description
Technical field
The utility model relates to a kind of anchor pole, specifically is the expansible anchor pole in a kind of end.Be mainly used in the reinforcement protection engineering in underground constructions such as foundation ditch, side slope, tunnel.
Background technology
In various underground constructions and geotechnical slope, preventive works, extremely extensive to the application of anchor pole.By the squeezing action of anchor pole to loosening ground body, link together tightly becoming flexible the stable anchoring ground body of ground body and deep layer.Anchor pole will play a role effectively, just must reliable anchoring will be arranged, and anchor pole often may be extracted from injecting cement paste or anchor pole is extracted from anchor hole together with injecting cement paste in the practice, carries or inefficacy thereby cause anchoring to be moved back, and brings potential safety hazard to engineering.
For strengthen anchor pole uplift resistance, Chang Yong method has two kinds in practice, first kind is the anchorage length that increases anchor pole, its weak point is to increase anchor rod anchored length then to increase the cementing agent consumption, cost is higher, anchor pole is whole stressed comparatively complicated.Second kind is exactly to increase anchoring termination volume, can effectively increase anti-pulling of anchor bar and increase the anchoring termination, and construction technology is simple, realizes than being easier to.
Summary of the invention
The utility model provides a kind of end expansible anchor pole, and the termination can strut in the anchoring process, increases anchoring termination volume.
The technical scheme that its technical problem that solves the utility model adopts is: the expansible anchor pole in a kind of end, it comprises actuating system and reaming system, described actuating system comprises drawing rope, inner sleeve, be enclosed within the outer sleeve of inner sleeve outside, be provided with a flange that has a drag-line duct in inner sleeve upper end, in the lower end of inner sleeve and the upper and lower end of outer sleeve all each device have identical connection to cut with scissors; Drawing rope is connected on passing the connection hinge of drag-line duct by the outer sleeve upper end and outer sleeve on the flange of inner sleeve upper end; Described reaming system comprises cornish bit and guide rod, at least 3 of guide rods, evenly distributing is installed on the lower end periphery wall of outer sleeve, and the cornish bit corresponding to guide rod is installed in the lower end of inner sleeve, and the lower end of guide rod is hinged and connected on the point midway of cornish bit by pin.
Described guide rod is connected by being connected hinge with the lower end of outer sleeve.
The upper end of described cornish bit is connected by being connected hinge with the lower end of inner sleeve.
This device is simple, in armature boring, do not need reaming, make the Counterboring apparatus of anchor bar body enlarge by drawing rope, cornish bit on the Counterboring apparatus opens, thrust in the ground body, slip casting then, thus effectively enlarged the termination point of anchor rod volume, form powerful resistance and pulled out body, increased the uplift resistance of anchor pole.
Its advantage is: termination point of anchor rod can strut, and the ground body is thrust in the termination, increases anchored force, improves the uplift resistance of anchor pole, and follow-up anchored force loss is little, has reduced follow-up maintenance cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is reaming end work schematic diagram.
Among the figure: 1. drawing rope, 2. flange, 3. inner sleeve, 4. outer sleeve, 5. guide rod, 6. cornish bit 7. connects hinge, 8. the pin hinge.
The specific embodiment
See figures.1.and.2, the expansible anchor pole in end is by drawing rope 1, flange 2, inner sleeve 3, outer sleeve 4, guide rod 5, and cornish bit 6 is formed.Outer sleeve 4 is enclosed within inner sleeve 3 outsides, is provided with a flange 2 in inner sleeve upper end, in the lower end of inner sleeve 3 and the upper and lower end of outer sleeve 4 all each device have identical connection to cut with scissors 7; At the lower end of outer sleeve 4 periphery wall equally distributed at least 3 guide rods 5 are housed, at the lower end of inner sleeve 3 internal perisporium device cornish bit 6 corresponding to guide rod 5 are arranged, the lower end of guide rod 5 is connected on the point midway of cornish bit 6 by pin hinge 8; Have the drag-line duct on the flange 2, drawing rope 1 links to each other with the hinge 7 that is connected of outer sleeve 3 upper ends by the drag-line duct on the flange 2 on the inner sleeve; Guide rod 5 is connected by being connected hinge 7 with the lower end of outer sleeve 4.The upper end of cornish bit 6 is connected by the hinge that is connected on the internal perisporium with the lower end of inner sleeve 3.
Hole earlier during use and afterwards put into anchor pole, withstand flange 2 on the inner sleeve with the vertically-displacable jack, drawing rope 1 is applied pulling force, drawing rope 1 moves upward under the pulling force effect, thereby tractive outer sleeve 4 and guide rod 5 move upward, and guide rod 5 drive cornish bits 6 move.Namely blocked by inner sleeve 3 wall positions after cornish bit 6 turns an angle, maximum opening angle has realized that the anchor pole end enlarges effect between 60～80 degree.
