Description

Technical Field

[0001] The present application relates to the technical field of exterior wall thermal insulation and waterproof structures, and in particular to an exterior wall thermal insulation and waterproof structure of a shallow silo and a construction method thereof. Background Art

[0002] A shallow silo is a cylindrical ground silo with a height-to-diameter ratio of less than 1.5, also known as a short silo. It is mainly used for large-scale storage of a single variety of grain and is suitable for central grain reserve depots. Therefore, the quality and safety of the grain must be guaranteed during the storage process.

[0003] Traditional shallow silos are usually made of cast-in-place concrete, which is prone to rainwater leakage and poor insulation, affecting the quality and safety of grain. In this regard, an airtight and waterproof structure of a grain shallow silo with announcement number CN219305472U is proposed. By placing grain inside a sealed silo, the vacuum layer isolates the air temperature outside the sealed silo, reducing the impact of the external air temperature on the inside of the sealed silo, and the constant temperature layer can keep the surface temperature of the outer wall of the sealed silo at a low temperature at all times, preventing the sealed silo from affecting the grain due to temperature changes. The insulation film can be applied to the surface of the silo. It plays the role of heat insulation and fire prevention inside. The refrigerator controls the temperature inside the constant temperature layer to keep the grain in a low temperature state for storage. The purpose of green insecticide and preservation is achieved by discharging carbon dioxide into the sealed warehouse for controlled atmosphere storage. At the same time, a one-way valve is provided at the bottom of the carbon exhaust pipe to prevent the air from flowing back inside the sealed warehouse. When it rains, rainwater is drained from the top cover to the drain port to reduce the accumulation of rainwater falling from the top cover to the ground, thereby reducing the condensation beads on the top cover and the warehouse wall. Thereby solving the problem of easy rainwater leakage and poor insulation effect of existing shallow round warehouses.
