| description | The utility model belongs to the technical field of tunnel and underground space pipe shed construction, particularly relates to a device for a long and large pipe shed segmented grouting process, and solves the problems that when an existing grouting device and an existing construction method are adopted for grouting of a long and large pipe shed, grouting slurry cannot reinforce the whole segment of surrounding rock at a time, the grouting effect of part of parts is not ideal, and the grouting effect is poor. Engineering potential safety hazards exist, and even serious safety accidents such as tunnel collapse are caused. The device is characterized by comprising a pipe shed, the pipe shed is in a pipe shape with the front end closed and the rear end open, and the closed end of the front end is in a pointed cone shape. A front end slurry outlet area is arranged at the position, 1-3 m away from the front end of the pipe shed, of the pipe wall of the pipe shed. One or more middle section segmented slurry outle |
