Abstract

The utility model relates to a novel self-broaching anchor rod. An anchoring section of the anchor rod is provided with a plurality of self-broaching devices in a spaced manner. Each self-broaching device comprises anchoring teeth; one end of each anchoring tooth is hinged to a fixed anchor rod sleeve disposed on the anchor rod; an intermediate portion of each anchoring tooth along a length direction is in hinge joint with one end of one dowel bar; the other end of each dowel bar is hinged to a movable anchor rod sleeve sleeved on the anchor rod movably; and the upper end of the movable anchor rod sleeve is contacted with an elastic device having one end fixed to the anchor rod. When the anchor rod is embedded in a soil body, the anchoring teeth are packed up and the anchor rod takes up less space; when an anchoring end reaches a predetermined position, the elastic devices provide the anchoring teeth with motive power for spreading and the anchoring teeth realize primary self-spreading; and when the anchor rod is applied a drawing force, the anchoring teeth spread out by the action of soil body resistance and jacking forces of the elastic devices. The anchoring teeth are embedded in soil through self-spreading of the anchor rod for improving pull-out resistance of the anchor rod; and after slurry is poured to broaching positions, the combination between the slurry and the self-broaching devices further improves the pull-out resistance of the anchor rod.

Description

Novel from hole reaming of anchor rod

Technical field

The utility model relates to a kind of anchor pole, especially a kind of can be widely used in that soil-slope reinforces novel from hole reaming of anchor rod.

Background technology

Traditional anchor pole all is to make the uniform section form, and uplift resistance mainly is to lean on anchoring body and surrounding soil to provide, and the value of being somebody's turn to do is less under the normal condition, and especially in soft clay area, because soil condition itself is relatively poor, anchoring effect is also corresponding relatively poor.The core content of anchoring research both at home and abroad is to improve aspect anchor structure or the construction technology at present, and with the enhancing anchoring effect, but a lot of method is not only constructed loaded down with trivial details but also cost is higher.

Summary of the invention

The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, provide a kind of simple in structure, easy to use, and cost is low, effectively shortens anchorage depth, saves the novel from hole reaming of anchor rod of boring, anchor pole and grouting length (or bolt diameter).

For realizing above-mentioned purpose, the utility model adopts following technical proposals:

A kind of novel from hole reaming of anchor rod, be provided with some on the anchoring section of said anchor pole at interval from Counterboring apparatus.

Saidly comprise the grappling tooth from Counterboring apparatus; One end of grappling tooth is articulated in the fixing anchor bar that is arranged on the anchor pole and puts; Along its length middle part and dowel bar one end is hinged on the grappling tooth; The other end of dowel bar is articulated in the movable anchor pole that is actively set on the anchor pole and puts, and the upper end of movable anchor pole cover contacts with the elastic force apparatus that an end is fixed on the anchor pole.

Said elastic force apparatus is a spring.

The utility model adopts novel from expanding the anchor pole technology, on anchor rod anchored section, is provided with novel from Counterboring apparatus at interval.Anchor pole is gone in the process of the soil body, and the grappling tooth is packed up, and the space that occupies is little, after anchored end reaches the precalculated position, provides the expansion of grappling tooth required power by elastic force apparatus (for example superpower spring), realizes preliminary from expanding.When anchor pole received tension, the grappling tooth strutted under the effect of soil body resistance and spring tension.The grappling tooth penetrated in the soil from expanding through anchor pole, to have strengthened anti-pulling of anchor bar, after the slip casting of reaming position, slurry with from the combining of enlarging device, can improve anti-pulling of anchor bar once more.Through realize the local reaming of anchor hole from hole reaming of anchor rod, to strengthen the slurry cross section at reaming position, grouting back; Simultaneously,, work, effectively increase anchoring tension pull out force, strengthen consolidation effect with slurry through the grappling tooth embedding soil body of self expandable.Effectively improve the slope reinforcement effect, when strengthening side slope safety, can shorten anchorage depth, saving boring, anchor pole and grouting length (or bolt diameter), reducing construction costs, having important society and economic implications.

Description of drawings

Fig. 1 is that the utility model is from expanding the anchor structure sketch map;

Fig. 2 is that the utility model is from the Counterboring apparatus structural representation;

Fig. 3 is a structural representation after the utility model reaming;

Wherein 1 anchor pole, 2 grappling teeth, 3 dowel bars, 4 elastic force apparatus, 5 fixing anchor bar covers, 6 movable anchor pole covers, 7 pin joints.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Shown in Fig. 1-3, a kind of novel from hole reaming of anchor rod, be provided with some on the anchoring section of said anchor pole 1 at interval from Counterboring apparatus.

Comprise grappling tooth 2 from Counterboring apparatus; One end of grappling tooth 2 is articulated on the fixing anchor bar cover 5 that is arranged on the anchor pole 1; Along its length the interface point 7 of middle part is hinged with dowel bar 3 one ends on the grappling tooth 2; The other end of dowel bar 3 is articulated on the movable anchor pole cover 6 that is actively set on the anchor pole 1, and the upper end of movable anchor pole cover 6 contacts with the elastic force apparatus 4 that an end is fixed on the anchor pole 1.Elastic force apparatus 4 is superpower spring.

The utility model adopts novel from expanding the anchor pole technology, on anchor rod anchored section, is provided with novel from Counterboring apparatus at interval.Anchor pole 1 is gone in the process of the soil body, and grappling tooth 2 is packed up, and the space that occupies is little, after anchored end reaches the precalculated position, provides 2 expansions of grappling tooth required power by elastic force apparatus 4 (for example superpower spring), realizes preliminary from expanding.When anchor pole 1 received tension, grappling tooth 2 strutted under the effect of soil body resistance and spring tension fully.Grappling tooth 2 is penetrated in the soil from expanding through anchor pole 1, has strengthened the globality of anchoring system, after the slip casting of reaming position, slurry through with from the combining of enlarging device, can increase substantially anchor pole 1 uplift resistance once more.

The use of the utility model is following:

1, makes novelly in advance, promptly on common bolt 1, install at interval from Counterboring apparatus (Fig. 2) from hole reaming of anchor rod (Fig. 1).

2, the boring at the soil-slope place that needs reinforcement, aperture should guarantee to insert smoothly shown in Figure 1 novel from hole reaming of anchor rod.When being bored into projected depth, stop boring.

3, after the cleaning boring, the novel insertion of making in advance from hole reaming of anchor rod holed.

4, open elastic force apparatus 4, provide 2 expansions of grappling tooth required power, realize from expanding.At this moment, grappling tooth 2 can penetrate the soil body.

5, carry out to a certain degree in advance stretch-draw to novel from hole reaming of anchor rod in the boring outside, grappling tooth 2 can darker penetrating in the middle of the soil body like this.

6, in boring, inject cement mortar, slurry through with expansion certainly after the combining of Counterboring apparatus, further improve uplift resistance.

7, health after the slip casting reaches anchor pole stretch-draw and locking after the design strength.
