Technical Field

[0001] The present invention relates to the technical field of agricultural facilities, and in particular to a low-cost air column type rain shelter and a construction method thereof. Background Art

[0002] Simple rain shelters are important rain protection facilities in crop cultivation. In fruit tree cultivation, they are widely used to protect grapes, cherries, bayberries, loquats and other varieties that are prone to disease or cracking from rain. It is also an important means to increase the sugar content of fruits and melons.

[0003] There are two main types of rain shelters on the domestic and foreign markets:

[0004] One type uses three upper and lower steel or plastic-coated cables mounted on columns as tensioning cables, with curtain-like buckles installed on the top and sides of the woven or ordinary shed membrane for retraction and expansion management. The other type uses fixed rain shelters, which, in addition to using steel cables, also incorporate bamboo or fiberglass rods to support the membrane in an arched shape to prevent water accumulation. Both of these traditional types of rain shelters are mostly constructed with columns spaced apart, with one upper and two lower steel cables mounted on them to support the shelter material. These cables, combined with buckles, allow for curtain-like retraction and expansion, allowing the shelter to be opened and closed. The standardized construction cost is generally around 20,000 yuan per mu. However, these traditional rain shelters suffer from complex construction processes, high wear and tear, and high costs.

After the material is inflated, a certain air column tension is formed, and an arch tension can be formed without the support of a skeleton. The air column tension can avoid water accumulation, and rainwater can be drained smoothly along the grooves between the air columns without any water accumulation.

[0026] 4. When the rainfall is ≥50mm / h, the time for rainwater to be discharged along the diversion groove of the arch surface formed by the inflatable air column membrane is ≤30 seconds, and there is no water accumulation on the roof surface; under the same conditions, the water accumulation depth of traditional fixed roof film can reach 5-10cm.
