AI Technical Summary

Technical Problem

Traditional road widening structures use rigid connections, and the impact force of vehicles passing through is directly transmitted to the curb, causing the concrete at the connection point to crack and the bolts to loosen. The construction period is long and cannot be adjusted, making it impossible to achieve rapid installation and adaptability to the ground.

Method used

By employing curb connecting plates, widening plates, buffer components, and support reinforcement mechanisms, and through the rotational engagement of lateral positioning bolts, shaft pins, and screw adjustments, a dynamic buffering and vibration reduction effect is achieved, adapting to settlement and support height adjustments, and enabling modular and rapid installation.

Benefits of technology

It provides dynamic buffering and vibration reduction, settlement adaptability and adjustable support height, reduces stress concentration at roadside connections, reduces maintenance needs, and improves construction efficiency and structural stability.
