AI Technical Summary
Existing guardrails used in construction projects cannot be lengthened according to needs and do not meet the installation requirements at different ground heights. Furthermore, the fixing method makes them susceptible to tipping over due to wind.
The guardrail adopts a telescopic pole structure and limiting components. By manually adjusting the pole length and fixing method, combined with threaded rods and cones inserted into the soil surface, the guardrail can be adjusted in length and stably fixed.
It enables the stable installation of guardrails on roads of different heights and lengths, reducing customization costs, improving applicability, and lowering the probability of safety accidents.
