The invention discloses a
coal gangue subgrade compaction degree detection method and facility. The
coal gangue subgrade compaction degree detection facility comprises a detection supporting frame. Device fixing mechanisms are arranged on the side face of the detection supporting frame. Two parallel movable sliding rails are arranged on the top of the detection supporting frame, a first movable sliding block and a second movable sliding block are erected on the tops of the movable sliding rails, and rotary locating mechanisms are arranged on the surfaces of the movable sliding rails. A
drill tube driving mechanism and a
road surface beating mechanism are arranged on the surface of the first movable sliding block and the surface of the second movable sliding block correspondingly. A detection
drill tube is connected with the bottom of the
drill tube driving mechanism, arc-shaped
cutting tools are arranged at the bottom end of the detection drill tube, and tips are arranged at the bottoms of the arc-shaped
cutting tools. A depth locating plate is fixedly connected with the exterior of the detection drill tube, and scales which are uniformly distributed are arranged on the inner wallof the detection drill tube. By the adoption of the
coal gangue subgrade compaction degree detection facility, measurement of the compaction degree of a
coal gangue road can be more easily accomplished, the detection efficiency is improved, the damage to the
road surface in the detection process can be reduced, the traffic is prevented from being affected, and the repair difficulty can be reduced.
