Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings.

[0026] Such as Figure 1 to Figure 5 As shown, the anchoring device integrated with drill-anchor high-pressure grouting of the present invention includes:

[0027] A rotary joint, the rotary joint includes a rotating shaft 13, a sleeve 16 and a rotating seal assembly. The rotating shaft 13 and the sleeve 16 are rotationally sealed and connected by the rotating seal assembly, and the rotating shaft 13 is provided with a grouting through hole 132 and a grouting through hole 132. It includes a connected radial hole and an axial hole. One end of the radial hole away from the axial hole extends out of the outer wall of the rotating shaft 13. The axial hole is a blind hole structure, and one end extends to the end surface of the rotating shaft 13. An injection hole 161 is provided on the sleeve 16 , And the injection hole 161 can communicate with the radial hole of the grouting through hole ...

Abstract

The invention discloses a drilling anchor high-pressure grouting integrated anchor device. The drilling anchor high-pressure grouting integrated anchor device comprises a rotary joint and an anchor rod, and the rotary joint comprises a rotary shaft (13) and a sleeve (16); the anchor rod comprises a rod body (3) and an anchor head (5), the rotary shaft (13) is internally provided with a grouting through hole (132), the sleeve (16) is provided with an injection hole (161), the anchor head (5) is of an arrowhead-shaped structure, an anchoring agent through hole (9) is formed in the outer wall, close to an arrowhead part, of the anchor head, and a choke plug (8) is arranged on the small end part of the anchor head (5); the rotary shaft (13) is detachably connected with the rod body (3), and the grouting through hole (132) communicates with the inner part of the rod body (3). In use, the rotary shaft (13) is connected with the rod body (3), the other end of the rotary shaft (13) is connected with a drilling machine, and the injection hole (161) is connected with high-pressure water. An anchoring agent package is pushed by the high-pressure water, and an anchoring agent is fixed to the rod body (3) and surrounding rock in an anchoring mode. Then the high-pressure water is introduced, the choke plug (8) is opened by the anchoring agent, and thus high-pressure grouting is achieved.

Description

Technical field [0001] The invention discloses an anchoring device integrated with drilling and anchoring and high-pressure grouting, which belongs to the technical field of anchoring appliances and bolt installation. Background technique [0002] The resin anchor rod is mainly used to fix the anchor rod and the surrounding rock through a resin anchoring agent, while the existing resin anchor rod mainly includes various material rod bodies, trays, nuts and other components. One end of the rod body is the anchor head. The material that plays the role of bonding and anchoring is an anchoring agent. The resin anchoring agent is divided into two parts, resin cement and curing agent, and packaged into a roll shape. After mixing, the rod body can be bonded with the anchored solid coal and rock. [0003] At present, when the resin anchor rod is actually used, it needs to be drilled first. After the hole is drilled, the anchoring agent is manually installed into the hole, and then the anch...
