Treatment equipment for preventing highway subgrade from sinking
ActiveCN222139704Uprevent sinkingQuality assuranceRoads maintainenceSoil preservationFixed bearingTruck
The utility model provides treatment equipment for preventing a highway roadbed from sinking, and relates to the technical field of roadbed sinking prevention. A through round hole is formed in the middle of the fixed bearing plate, and threaded grooves are evenly formed in the edge of the upper end of the round hole. The road subgrade tamping device can stably fall on a subgrade through stable guiding of the tamping block, tamping treatment is conducted on the subgrade, the stability and durability of the road subgrade are improved, subgrade sinking is effectively prevented, the service life of a road is prolonged, the tamped subgrade can be effectively detected in advance through the detection column, the tamping effect can be checked in time, and the detection efficiency is improved. Problems can be timely corrected when found, and the problems that the roadbed sinks to influence traffic due to the fact that the roadbed is pressed down by rainwater or vehicles after being used for a long time, the laid roadbed needs to be tamped in advance and effectively detected, otherwise, the roadbed is collapsed when a plurality of heavy trucks pass through the roadbed, and potential safety hazards are caused are solved.
