Abstract
The utility model discloses an injection type hollow resin bolting which consists of a nut, a piston, a stop-grounting plug, a rock bolt body, agent and a check valve. The nut is installed at one end of the rock bolt. The piston is installed on the hollow position of one end of the rock bolt body. The stop-grounting plug is installed in the rock bolt body which is provided with the piston, and penetrates the rock bolt body to the outside. The agent is filled in a chamber of the rock bolt boy. The check valve is installed at the other end of the rock bolt body. Due to the fact that the external thread of the rock bolt body is directly matched with the nut, the threads is capable of increasing combining effect of the rock bolt and resin or cement mortar, and anchoring construction operation is further simplified.
Description
Technical field
The utility model relates to the anchor pole field, especially relates to a kind of internal-injection type hollow resin anchor pole.
Background technology
At present, mainly contain screw-thread steel resin anchor and a small amount of fiber glass resin anchor pole etc. on the market, its solid power is not strong, easily fracture, and underground construction is complicated, and efficient is not high, and the novel invention of this use can solve this class technical problem.
The utility model content
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model provides a kind of internal-injection type hollow resin anchor pole of simplifying the anchoring construction operation.
The utility model takes following technical scheme to realize: a kind of internal-injection type hollow resin anchor pole, it is comprised of nut, piston, stop grouting plug, anchor bar body, medicament and non retern valve.Described nut is installed in an end of described anchor bar body, described piston is installed in the hollow part of an end of described anchor bar body, described stop grouting plug is installed in the described anchor bar body that described piston is installed, and pass anchor bar body to outside, described medicament is filled in the chamber of described anchor bar body, and described non retern valve is installed in the other end of described anchor bar body.
The hollow part of one end of described anchor bar body is equipped with described piston.
The utlity model has in sum following beneficial effect: the utility model utilizes the anchor bar body external screw thread directly and nut cooperates, screw thread can increase anchor pole and resin or cement mortar in conjunction with effect, can simplify anchoring construction and operate.
