Resin stock suitable for soft rock roadway support

The patent of the utility model relates to a resin stock suitable for soft rock roadway support is by resistance to plucking head, the body of rod, rubber granule concrete, let and press the tray and the nut that excels in to constitute. Resistance to plucking head and inside resin cartridge combined action are mainly passed through in the anchor of this stock, and the holistic pressure that lets presses the rubber granule concrete in tray and the tray to realize by letting. Make the resistance to plucking head open through strikeing the pole tail, resin cartridge is by crowded broken afterwards. After accomplishing the anchor, will fill with letting of rubber granule concrete through the nut that excels in and press the tray cover at the stock body of rod and hug closely and enclose rock -wall. This structural design is reasonable, and simple to operate can effectively solve the nature complicated and changeable of secret geotechnical engineering condition and the high current variability of soft rock, has i
