The nine concrete silo projects in Algeria are designed with a total capacity of 350,000 tons. The silos are distributed in nine provinces, of which four provinces have a construction scale of 50,000 tons and an output of 300 tons per hour, and five provinces have a construction scale of 30, 000 tons and an output of 200 tons per hour.
The 50, 000-ton silo project in Constantine completed on the same day is currently the country's largest grain storage facility, with a production capacity of 300 tons per hour. The project is also among the first of large scale granary construction projects launched in Algeria in the past 40 years.
This project is an example of overcoming multiple technical difficulties including complex geological conditions and harsh weather conditions by adopting advanced technology, strict specifications and standards ensuring both structural safety and economic factors.
The design of this project has to conform to the French norms within the framework of the EU standard, it is also necessary to comply with the Algerian local standards. The civil engineers involved in the project carefully studied and compared the code systems they need to follow and applied internationally accepted structural calculation software (SAP2000, ROBOT and ETABS) to conduct the design. Through painstaking technical demonstration with the CTC Audit and drawing Agency, the local design institute and the supervision company, COFCO plan passed technical review with serious attitude, strong technical solutions and extensive experience.
Aiming for an economically reasonable plan, multi scheme comparison and selection was conducted. The final plans for the nine projects have adapted to the geological conditions of each individual place, to achieve the best cost-effective performance. There are three main categories: pile foundation, raft foundation and box foundation.
Algeria is a food importing country. This project will make important contributions to the improvement of the country’s grain logistics system. At the same time, it will provide a strong guarantee for the country's food supply security and will generate huge social and economic benefits.
As an important achievement of COFCO Engineering & Technology (Zhengzhou)’s overseas grain storage design project, this project is of great significance for the company to continue its exploration of the international market.
