Description

Technical Field

[0001] The utility model relates to the technical field of sampler brackets, and specifically relates to a measuring tripod for road construction. Background Art

[0002] A measuring tripod for road construction is an important and indispensable tool in road construction. It is mainly used to support and stabilize various measuring devices and experimental instruments to ensure the accuracy and efficiency of measurement. The materials of the tripod usually include wood and aluminum, etc. The wooden tripod is solid, durable, waterproof, insect-proof, not easy to deform, and has strong stability. It is suitable for measurement scenarios with high precision requirements, long measuring station time, and slow measuring station speed. The aluminum tripod has strong stiffness, is corrosion-resistant to touch, and has relatively light weight, which is convenient for long-term manual carrying and reduces the work intensity. It is suitable for measurement scenarios with low precision requirements, short measuring station time, and fast measuring station speed. The measuring tripod usually consists of three legs and a connecting rod, which is used to support and stabilize various measuring instruments and equipment. Its design aims to improve the accuracy and efficiency of measurement and reduce human errors.
