In the traditional construction of shallow silos, the construction methods of silo walls and roofs have been fixed. Although the technology is relatively mature, efficient, convenient, safe and reliable, there are still some shortcomings. With the continuous acceleration of the construction of grain depots in China in recent years, the construction quality requirements for this kind of indemnificatory buildings are becoming higher and higher, the regulatory authorities have also put forward stricter requirements. Taking the construction of shallow silos in the construction project of Renhe Grain Reserve in Hangzhou as an example, the weak points of the traditional construction method are analyzed. Through continuous calculation, test and practice, the control device of the reinforcement protection layer is added to the sliding form construction of the silo wall, the Bailey steel truss support system for the construction of the silo top structure is improved and innovated, and a kind of external hanging frame base device for the silo top is researched, which improves the construction technology of the shallow silo of the grain depot, not only ensures the construction quality and safety, but also greatly reduces the construction cost, the overall application effect is good.
