AI Technical Summary

Technical Problem

Traditional cast-in-place concrete supports have long construction cycles and their quality is greatly affected by site conditions. Precast assembled supports have insufficient joint strength, making it difficult to meet the vibration and impact resistance requirements of hydraulic structures. Furthermore, the existing precast supports lack modularity and are difficult to adapt to complex load conditions.

Method used

The fully prefabricated steel-node concrete pipeline support adopts modular prefabrication and steel node rigid connection technology to achieve factory production and rapid assembly. It uses multiple prefabricated concrete pipeline support units, including top and bottom prefabricated concrete beams and prefabricated concrete columns, combined with a composite structure of steel fiber concrete protective shell, middle corrugated steel pipe and inner concrete core. It uses steel node rigid connection and prefabricated concrete longitudinal beams to connect adjacent units.

Benefits of technology

It improves construction efficiency and quality, enhances the load-bearing capacity, seismic performance and durability of the support, ensures the safety and reliability of the project, and is suitable for complex load conditions of hydraulic structures.
