Anchor construction method A, prepare: drill rig in place and connect the power supply, water supply pipeline. B, measuring cloth eye: According to the rock bolt design spacing and perinatal management, joint distribution of the actual situation, marked with paint eye position. Of bedding and joint development area, when the cloth laid eyes need encryption. C, Drilling: Drilling with two arm hydraulic trolley drilling, drilling drill perpendicular to the rock face or bedding plane. D, hole cleaning and inspection: the hole in the net with a high-pressure wind stone chips and small stones, conducive slurry full contact with the rock, and check the depth of the hole. E, anchor processing: Class Ⅱ Φ25 using steel anchor bolt tension meter, Henan, according to the design size material, the exposed ends of the range within 20cm tapping, wire port after its depth and the diameter of the bolt ends forming mats matching plate. F, into chemical kits: slightly smaller than the pore size with chemical kits lightweight PVC pipe into the bottom of the top bolt hole, taking into sub-sections, and then out of PVC pipe. Then into groups for kraft pulp plug. G, bolt insert: insert the bolt with a hammer to tap the bolt plug the hole bottom, then rotate the rod, the inner spacer layer slurry chemistry kits destroyed two Binzhou bolt tension meter, so that rapid chemical reaction slurry anchor bolt ends. Slurry solidification takes about 3 minutes, during which the need to manually help steady anchor. H, on the plate and nuts: end anchor is completed, then insert φ6 and φ10 grouting pipe exhaust pipe Heze bolt tension meter, then the seal plate, anchor plate and M20 nut and tighten applying a small amount of pre-afterburner facilitate rock steady. I, grouting: The BW250 mortar pump grouting, grouting pressure 0.1 ~ 0.3Mpa. 1:1.5 cement slurry material bolt tension meter, mortar, mortar mixing machine using the on-site mixing, mixing time of less than three minutes. When grouting uniform injection of the slurry evenly until the exhaust pipe outflow, the full grouting.
