Description

Technical Field

[0001] This utility model relates to the field of testing auxiliary equipment technology, specifically a road and bridge testing auxiliary device. Background Technology

[0002] Roads and bridges are generally constructed of concrete. During construction, it is necessary to sample and test the concrete at different depths to prevent safety hazards caused by poor-quality concrete. Road inspections typically include inspection of major materials, on-site inspection of subgrade soil compaction, subgrade inspection, on-site inspection of pile foundations, subgrade and base course deflection testing, pavement core inspection, sewage pipeline sealing water test, water supply fire test, and gas pipeline pressure test. Depending on the specific road construction project, inspections are required for items necessary to ensure quality and acceptance.

[0003] Most existing auxiliary devices for road and bridge engineering inspection are fixed in place, making it impossible to adjust the position of the inspection equipment. This leads to inconvenience when replacing other equipment, and requires additional ground cleaning before inspection, resulting in slow work efficiency and increased labor consumption. To address these issues, we offer a road and bridge inspection auxiliary device. Utility Model Content
