Coal gangue subgrade compaction degree detection method and facility

Abstract

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.

Description

technical field [0001] The invention relates to the field of detection of compaction degree, in particular to a method and detection equipment for detection of compaction degree of coal gangue subgrade. Background technique [0002] Coal gangue road is a road paved with coal gangue as the main material. Coal gangue is solid waste discharged during the coal mining process and coal washing process. Dark gray rock harder than coal. Coal gangue includes excavation gangue during roadway excavation, gangue extracted from roof, floor and interlayer during mining, and gangue picked out during coal washing. [0003] Coal gangue will occupy a large area of ​​land if it is not used. The escape or leaching of sulfide in coal gangue will pollute the atmosphere, farmland and water bodies. Gangue hills can also spontaneously ignite and cause fires, or collapse during the rainy season, silting up rivers and causing disasters. The accumulated coal gangue in China has reached more than 1 ...

AI Technical Summary

Problems solved by technology

[0007] (1) The degree of compaction measured by the sand filling method will seriously damage the road surface, especially after multiple measurements, it will leave more potholes on the road surface, which not only affects normal traffic, but also increases the difficulty and difficulty of repairing the road surface. funds;

[0008] (2) The operation steps of the sand filling method are cumbersome, and when measuring the compactness of the road surface, multiple measurements are required, so the entire detection process takes a long time and has many steps, which is not only inefficient, but also increases work. staff burden
