AI Technical Summary

⚠Technical Problem

Existing technologies for reinforcing protective walls with formwork require drilling holes in the bridge, increasing bridge maintenance costs.

⚗Method used

A new type of formwork and support device for the construction of protective walls for high-speed railway bridges is adopted. The formwork is fixed by I-beams and wooden wedges at the drainage holes, avoiding drilling holes on the beam surface. The formwork is supported and limited by I-beams, pads, fixing connectors and other components.

🎯Benefits of technology

This method eliminates the need to drill holes in the beam surface to fix the formwork, reducing maintenance costs and preventing formwork bulging.
