| Abstract: | In order to improve the support and reinforcement effect of bolt on roadway,a spiral wound grouting bolt was proposed. The structure and processing technology were designed,and the mechanical properties were studied by test method. The results show that the better mechanical properties can be obtained when the helix angle is 15° and the annealing temperature is 400 ℃. |
