| description | The invention relates to a self-propelled rod body and method for tunnel soft and hard interbedding rock mass grouting construction. The self-propelled rod body comprises a supporting rod body which is used for being connected with the percussion drill and supporting the whole self-propelled rod body in the process that the percussion drill drives the self-propelled rod body to enter the soft and hard interbedded rock mass of the tunnel. The grouting pipe body is arranged on the supporting rod body in a sleeving mode, and after the self-propelled rod body enters the tunnel soft and hard interbedded rock mass and the supporting rod body is pulled out, the grouting pipe body is reserved in a tunnel soft and hard interbedded rock mass hole and used for grouting; and the drill bit is fixed on the body part of the supporting rod. The self-propelled rod body for tunnel soft and hard interbedded rock mass grouting construction is used as a whole and has high overall strength, and in a soft and hard interbedded tunne |
