Description

Technical Field

[0001] The utility model relates to the technical field of grain storage buildings, and more specifically to a rainwater drainage structure for a shallow silo roof. Background Art

[0002] Shallow silos are the main type of silo for grain storage in my country. They are found all over my country due to their small footprint, high degree of mechanization, and large silo capacity. The key and difficulty of traditional shallow silo construction lies in the construction of the silo roof. This location is a dangerous project with a large construction unit and is prone to engineering accidents. The existing technology uses scaffolding to build the roof template at high altitude, which is dangerous, has a long construction period, and is expensive to rent scaffolding.

[0003] The existing patent is a shallow silo top cover and a shallow silo, and the patent authorization number is CN 219780968 U. By setting a steel frame, the use of scaffolding is omitted, and the dangerous high-altitude formwork is changed to assembling the steel frame on the ground, which improves work efficiency, reduces manufacturing costs, and ensures personal safety.

[0004] However, in the patent authorization number CN 219780968 U, a drainage ditch is also arranged in a circumferential direction on the upper edge of the silo wall, and a drainage port is opened on the drainage ditch to collect and discharge the drainage from the roof on rainy days. Since the rainwater falls directly from the drainage ditch, affected by the height of the silo body, the potential energy of the falling rainwater is large, and it washes in and out of the foundation, affecting the stability of the foundation for a long time. Therefore, we proposed a shallow circular silo roof rainwater discharge structure to solve the above-mentioned problems. Utility Model Content
