Another object of the present invention is to the construction method that a kind of barb grouting formula anchor pole is provided.
For achieving the above object, the invention provides a kind of barb grouting formula anchor pole, comprising: the body of rod, it is inner in cavity structure, and described cavity is for holding slurry; Barb plate, its mobilizable front portion being located at the described body of rod; And push rod, itself and described barb plate active link, described push rod is located on the described body of rod, and can move radially along the described body of rod, with drive described barb plate open and closed; Under the state that described barb plate opens, grouting material in described body of rod cavity, the gap that slurry is formed by described barb plate and the described body of rod is overflowed.
Preferably, in technique scheme, also comprise push rod, its one end and described push rod hinged, the other end is slidably located in the top board guide groove of described barb plate.
Preferably, in technique scheme, the outer wall of the described body of rod is provided with the spacing preiection limiting described push rod displacement.
Preferably, in technique scheme, described barb plate is 4 pieces, and uniform ring is set around the external surface of the described body of rod.
Preferably, in technique scheme, the described body of rod is provided with push rod guide groove, and described push rod is located in this push rod guide groove, and can slide in described push rod guide groove.
Preferably, in technique scheme, the described body of rod is the conehead body of rod.
A construction method for hook grouting formula anchor pole, comprises the following steps:
(1) slope body is holed, implement reaming at the bottom of drilling hole, make the cavity forming the barb plate that can hold when being in open configuration at the bottom of hole;
(2) anchor pole first barb plate being in closure state inserts in the hole, and then promotes push rod, and push rod promotes barb plate and opens, and then fixes push rod;
(3), toward grouting in the cavity of the body of rod, after grouting, the rear portion toward anchor pole adds upper padding plate, baffle ring and concrete capping.
Compared with prior art, the present invention has following beneficial effect: barb grouting formula anchor pole of the present invention, when barb plate opens, anchor pole is made to have barb, improve the uplift resistance of anchor pole, be also not easy to produce after long-time use and slide, ensure that the safety of slope reinforcement.Construction method of the present invention, its construction is convenient, increases work efficiency, economical good.
