Grouting pipe for tunnel passing through waste rock yard made through manual accumulation

The utility model provides a grouting pipe for a tunnel passing through a waste rock yard made through manual accumulation. A seamless steel pipe with the diameter being 48 mm and the thickness being 4 mm is adopted as the body of the grouting pipe, the front portion of the body is a tunneling end, a plurality of grout pressing holes are formed in the circumferential surface of the body, the distance between every two adjacent grout pressing holes is 150 mm, the grout pressing holes are distributed in the circumferential surface of the body in the shape of a plum blossom, the periphery of the rear of the body is sleeved with a rebar hoop, and the distance between the rebar hoop and a feed inlet in the tail of the body is 150 mm. The grouting pipe is wide in application range, and the grouting pipe is not only applicable to the situation that the tunnel passes through waste rock and waste soil made through manual accumulation and other special stratums, but also applicable to the situation that the tunnel passes through a fault which is very loose or broken, tunnel collapse treatment and surface soil layer construction. Construction progress is high, disturbance of surrounding rock is small, supporting follows up in time, and operation safety is greatly improved.
