The invention relates to the technical field of supporting, in particular to a bearing system and a grouting anchor rod, comprising: a drill body assembly including a rod body, a grouting channel integrally formed in the rod body, a slurry outlet penetrating through the outer wall of the rod body and communicating with the grouting channel, and a drill bit arranged at one end of the rod body; the protecting bush assembly comprises a protecting bush arranged on the outer wall of the rod body and a grout stopping plate arranged at one end of the protecting bush, the anchor rod can be deformed into an expansion piece, the grout outlet can be protected, and the friction force between the whole anchor rod and a rock-soil layer can be improved; the bearing system provided by the invention can be used for effectively bearing the anchor rods, so that the falling phenomenon in the transportation process is avoided, and the problems in the prior art are solved.
本发明涉及支护技术领域,特别是种承载系统及注浆锚杆,包括,钻体组件,包括有杆体、一体成型于所述杆体内的注浆通道、贯穿开设于所述杆体的外壁并与所述注浆通道连通的出浆口,和设于所述杆体一端的钻头;以及,护套组件,包括有设置于所述杆体外壁的护套以及设置于所述护套一端的止浆板,本发明所提供的锚杆可以变形为膨胀件,不仅可实现对出浆口的防护,还能够提高锚杆整体与岩土层之间的摩擦力;而本发明提供的承载系统可以对各锚杆进行有效承载,避免在运输途中出现掉落现象,从而解决现有技术中存在的问题。
