Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as Figure 1 to Figure 5 As shown, the installation process of a new type of drilling, anchoring and injecting integrated resin anchor rod of the present invention includes the following steps:

[0032] a. Select swivel joint and anchor rod,

[0033] 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 connected in a rotating and sealed manner through the rotating sealing assembly, and the inside of the rotating shaft 13 is provided with a grouting through hole 132, the grouting through hole 132 It includes a connected radial hole and an axial hole. The 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. T...

Abstract

The invention discloses a mounting process of a novel drilling, anchoring and grouting integrated resin anchor rod. The mounting process comprises the following procedures: a, selecting a rotary jointand an anchor rod; b, drilling an anchor rod hole to enable the anchor rod hole to meet the requirement; c, placing an anchoring agent bag (6) in an anchor rod body (3), and inserting the anchor rodinto the anchor rod hole; d, detachably connecting one end part of a rotating shaft (13) of the rotating joint with one end of the anchor rod body (3), then connecting a high-pressure water pipe (24)with an injection hole (161) formed in a sleeve (16) of the rotating joint, and opening a valve of the high-pressure water pipe (24) until anchoring is completed; e, connecting the other end of the rotating shaft (13) of the rotating joint with the output end of drilling equipment (23); and f, starting the drilling equipment to pre-tighten the anchor rod. According to the process, uniform mixing of the anchoring agent, anchoring, pre-tightening and high-pressure grouting can be integrated, and the problems that an existing resin anchor rod is complex in mounting process, high in technical requirement for the mounting personnel, high in failure rate and the like are solved.

Description

technical field [0001] The invention discloses a novel drilling, anchoring and injecting integrated resin bolt installation process, which belongs to the technical field of resin bolt installation. Background technique [0002] Resin bolts are mainly fixed to the surrounding rock by resin anchoring agent, and the existing resin bolts are mainly composed of various material rod bodies, trays, nuts and other components, one end of the rod body is the anchor head, and the outer wall of the rod is provided with The thread, the tray and the nut are sleeved on the rod body in sequence. The material that plays the role of bonding and anchoring is anchoring agent. The resin anchoring agent is divided into two parts, resin cement and curing agent, and packaged into a roll-shaped anchoring agent package. After mixing, the rod body and the anchored solid coal and rock can be bonded together. [0003] And the main process of existing coal mine roadway resin bolt support construction te...
