Highway engineering roadbed compactness check out test set

Technical Field

The utility model relates to the technical field of highway engineering, in particular to highway engineering subgrade compactness detection equipment.

Background

Highway engineering refers to the work of investigation, measurement, design, construction, maintenance, management, etc. of highway structures. The compactness of the roadbed is one of key indexes for detecting the construction quality of the roadbed and the road surface, the density condition after the on-site compaction is represented, the higher the compactness is, the higher the density is, the better the overall performance of the material is, and in the road engineering construction process, whether the roadbed meets the quality requirement is judged. There are various detection methods, such as a sand irrigation method, a water irrigation method, etc., wherein the methods all require pit-digging sampling of the roadbed.

The existing roadbed compactness detection sampling mode is mostly sampled by using shovels and the like manually, or pit digging sampling is carried out through exposed screw rods, the manual sampling working strength is high, if pit digging sampling is carried out through simple screw rods, soil splashing is easily caused in the sampling process due to the lack of a protection structure, meanwhile dust can be generated, and the body health of workers is influenced; meanwhile, when the drill bit is used for detecting roadbed, soil and the like are dug out to scatter on the roadside during detection, and the manual later-stage cleaning is required, so that the roadbed is more complicated.
