A complete set of centrifugal manufacturing technology for extra large size concrete components won the first prize of 2020 CCPA Concrete Science and Technology Award (Technology Innovation).

With the development of deep-sea construction engineering and highway, new manufacturing technology of extra large size concrete components is demanded to meet the requirements of intelligent manufacturing and intelligent construction. The traditional concrete cast-in-place technology has a series of problems in quality control, long construction period, environmental pollution and so on. It greatly restricts the industrial production of concrete components and even affects the development of infrastructure construction.

A complete set of centrifugal manufacturing technology for extra large size concrete components has applied in many constructions, such as Hong Kong-Zhuhai-Macao Bridge, Heruo Railway, Shanghai Hongqiao Transportation Center and so on.

The main innovations of the project are as follows

l High performance concrete series technology of extra large centrifugal component.

lAutomatic production technology of large size and double layer reinforcement cage.

lA complete set of extra large size high speed centrifugal molding technology

lMaintenance system for extra large size, thick wall, asymmetric and other components.

lAutomatic recovery and recycling technology of waste liquid from centrifugal slurry.
