Product Features

01/

Prefabrication Advantages

• High Efficiency & Energy Saving: Automated production line achieves ≤50 minutes per unit, increasing daily output by 40% vs traditional methods.

• Controlled Quality: Mold precision (±1mm), concrete compaction ≥98%, and product pass rate >99%.

• Eco-Friendly: Factory prefabrication reduces on-site dust / noise pollution, complying with green construction standards (GB/T 50640).

02/

Modular Design

• Rapid assembly / disassembly for flexible trench size production.

• Built-in embedded part locators (lifting holes / bracket slots) eliminate on-site modifications.

03/

High-Performance Joints

• Dual silicone gaskets (IP68) prevent water ingress.

• CNC-machined endplates ensure ≤1.5mm joint misalignment for seamless connections.

04/

Smart Production Support

• IoT sensors monitor vibration (40±5Hz) and pressure (0.2–0.5MPa) for optimal concrete quality.

• BIM-compatible interfaces enable digital twin production management.
