Anchor cable construction device combining hole forming, mounting and grouting into one
The invention discloses an anchor cable construction device combining hole forming, mounting and grouting into one. The anchor cable construction device comprises a drill rod assembly and a push-pull power system, the drill rod assembly comprises a drill rod, a drill bit and a hydraulic power motor, the drill rod is hollow, the hydraulic power motor, a grouting pipe and an oil supply pipeline are arranged in the drill rod, the hydraulic power motor is fixed in the hole drilling end of the drill rod, a grouting hole is formed in the hole drilling end, and the drill bit is arranged on the hydraulic power motor. A plurality of grooves extending in the length direction of the drill rod are distributed in a rod body of the drill rod at intervals in the circumferential direction. A plurality of anchor cable penetrating holes are formed in the inner side wall of the hole drilling end of the drill rod at intervals in the circumferential direction, an inclined channel is communicated between each anchor cable penetrating hole and the corresponding groove, and the inclined channels extend from the anchor cable penetrating holes to the other end of the drill rod. The drill rod is provided with an anchor cable separator used for clamping an anchor cable placed in the grooves in the hole retreating and pulling out process. The anchor cable construction device is higher in operability and wider in application range, construction time can be greatly saved, and construction efficiency can be improved.
