Road subgrade compactness detection system

Abstract

The invention discloses a road subgrade compactness detection system, which comprises a transport vehicle body, the middle of the transport vehicle body is slidably sleeved with a sliding type sampling mechanism used for sampling work, the bottom of the transport vehicle body is welded with a sliding chute type protective cylinder in a penetrating manner. The sliding type sampling mechanism moves up and down, so that the sampling work can be better carried out; in the process of moving the sliding type sampling mechanism, an object recognizer recognizes an object, and meanwhile, a laser distance measuring sensor also detects the downward moving distance of the sliding supporting plate, so that the thickness of the laid roadbed can be quickly calculated, and a worker can obtain accurate data; in the transportation process of the telescopic transportation mechanism, the convex block is in contact with the first mechanical switch and the second mechanical switch respectively, so that the first mechanical switch and the second mechanical switch can control the sliding sampling mechanism to move up and down, the sampling work is automatically completed, and the physical strength and time of workers are saved.

Description

technical field [0001] The invention relates to the technical field of road detection equipment, in particular to a road subgrade compactness detection system. Background technique [0002] The degree of compaction, also known as the degree of compaction, refers to the ratio of the dry density of soil or other building materials after compaction to the standard maximum dry density, and is expressed as a percentage. The degree of compaction is one of the key indicators for the quality inspection of subgrade and pavement construction. It represents the density status after on-site compaction. The higher the degree of compaction, the greater the density, and the better the overall performance of the material. For subgrades, pavement semi-rigid bases and granular flexible bases, the degree of compaction refers to the ratio of the dry density actually achieved on the construction site to the maximum dry density obtained from the indoor standard compaction test.

Problems solved by technology

[0003] When the existing roadbed compactness testing equipment is sampling the roadbed, the staff needs to manually put the sampled samples into the storage channel, which will easily cause the mixing of different objects on the roadbed, thus It will affect the accuracy of the detection data, and it is time-consuming and laborious
