Under the guidance of Ma Fuli, the team composed of sun Yihao, Guo Pei and he Gaole won the third prize, This is the first time our school has won a prize in this event.

Affected by the epidemic situation, the finals were conducted online. Our team gave full play to the mechanical properties of materials. The on-site operation was based on the pile wall support system, added horizontal tension belts, and used the support ring to arch the retaining structure panel and tension belt, so that as many materials as possible could bear tension during the stress process of the retaining structure, which impressed the competition referee team, Praised as "fantastic ideas".

The extracurricular science and technology competition is an important starting point for cultivating excellent talents with solid theory and innovation practice in an all-round way. Through this event, more teachers and students will be encouraged to devote themselves to the upsurge of knowledge serving the country and scientific research innovation, and contribute to the national infrastructure construction and scientific and technological power!
