How to Strengthen Windbreak in Spring Arch

Spring is the season with the strongest air convection during the year. The cold air in the north gradually recedes. The warm and humid air in the southwest and southeast gradually strengthens. The warm and cold air comes and goes. It is the strongest season in the year. In the spring, winds of grades 6-7 are common and the sheds are easily damaged. The vegetable farmers must do a good job of preventing winds.

1. Set more film rope when there is a tall object on the shed

According to many years of experience, if there are tall objects such as houses, trees, etc. near the arch shed, strong winds will cause cyclones or turbulence due to the obstruction of these objects, especially when these objects are in the south direction of the arch, the swirling airflow After being blocked, they descended and entered the shed through the entrances and exits with more gaps on the south side of the shed, causing inconsistent air pressure in the sheds and possibly damaging the shed film. It is suggested that the peasants with tall objects near the arch shed increase the number of membrane ropes and close the entrances and exits of the arches to prevent the air flow from entering.

2. Arch shelters with small shed face angle and high sides should strengthen wind protection work

Arch sheds with small sheds and high sheds on both sides of the shed are more resistant to wind. If the air vents are not strict, the pressure inside and outside the sheds will be different when the air flows through the shed, and the shed film will move up and down to blow the shed film. Seriously, it may cause the entire arch to collapse. Therefore, such a shed is to transform the arch structure, reduce the height of both sides of the column, strengthen the bearing capacity of both sides of the column, increase the shed face, the second is to increase the number of shed membrane pressure, close the vents, improve the shed Body's wind resistance.

3. Add windproof film on both sides

For the windproof of the arch shelter, the vegetable farmer can install a windproof membrane at the bottom of the east and west sides of the arch shelter. The width of the windproof membrane should be suitable from the underground side of the arched ceiling to the uppermost air outlet, for example, when the west wind blows, the vegetable farmer will be on the west side. The windproof membrane is shielded, so that high winds can be prevented from entering the shed from the air outlet on the west side of the arch shed, preventing the wind from scratching the shed film. If the wind exceeds level 6, the arch shed will open the air outlet on the side of the leeward to ensure that the airflow in the shed is discharged, so that the windproof effect is better.
