The utility model adopts the following technical proposal:
the utility model provides a novel anchor rod for side slope support, its characterized in that, including a protection section of thick bamboo, slip casting chamber, stationary hump, slip casting pipe, external screw thread, link, bolt, stock, small opening, internal thread, drill bit, the stock is cylindric, and the stock top is equipped with the link, and the stock middle part is provided with stationary hump, and the stock lower part is equipped with the internal thread and is connected with the drill bit, a protection section of thick bamboo sets up in the outside at stock middle part, is connected with the stock through the bolt, is connected with the drill bit through the external screw thread, and the protection section of thick bamboo outside is equipped with 4 column slip casting pipes, and slip casting socle inboard is equipped with one row of small.
Preferably, the anchor rod and the connecting end are welded and cannot be detached.
Preferably, the positive spiral direction of the drill bit and the anchor rod and the positive spiral direction of the drill bit and the protective cylinder are consistent with the rotation direction of the drill bit.
Preferably, the length of a bolt connected with the anchor rod at the top end of the protection cylinder is 1cm, the top end of the protection cylinder is in a square design, 4 bolts are adopted for fixing, and after the anchor rod is fixed, the bolts are loosened by 0.5cm to serve as parts of the rotary protection cylinder.
Preferably, the bottom of the grouting pipe is hollow.
Preferably, the fixing protrusion is formed by welding a steel material and the anchor rod.
Preferably, the weep holes are circular and 3cm in diameter.
The utility model has the advantages that: (1) the problem that a large amount of time is needed for installation between the anchor rod and the rock-soil body is solved;
(2) the concrete can be more conveniently injected around the anchor rod and is in close contact with the rock-soil body;
(3) the anchoring force of the anchor rod can be greatly improved.
Drawings
