Rainproof measures for construction of glass greenhouse engineering

Greenhouse skeleton, summer is the season with abundant rainfall, and it is necessary to do a good job in timely protection and flood prevention of greenhouse engineering. More and more vegetable farmers monopolize the arch greenhouse for vegetable production.

During the summer and rainy season, two preparations should be made. Although there are many types of arched sheds nowadays, big or small, there are mainly two aspects to prevent rain: the top vent for rain protection. Nowadays, many arched greenhouse films are composed of two wide films and one narrow film. Therefore, during the construction of high-temperature greenhouses, the position of the air outlet is at the top of the large arched greenhouse. Even if the air outlet is closed during rain, rainwater will still flow into the greenhouse from the top due to irregular discharge. The rainwater will fall on the vegetable stems and leaves inside the greenhouse, which can easily transmit diseases, and in severe cases, it can cause vitality waterlogging.

So, the rain protection of the upper air vent becomes particularly important. Regarding this, it is recommended to install a rainproof film on the top.

Prepare a plastic film first, old greenhouse film is also acceptable, as long as it is not broken or destroyed (but the transparency should be as good as possible to prevent severe shading). The length of the shed is the same but not the same, and the width depends on the size of the air outlet. It only needs to provide pure rain resistance after hanging, and generally 3-4 meters is suitable. From now on, each side of the greenhouse film is strung together with a wire, with the upper end fixed below the large arch greenhouse film, the two ends fixed with wire, and the middle secured with a thin rope.

And its lower end can be fixed to the column under the air vent, so even if rainwater enters the shed, it will probably flow down and into the water channel. Secondly, it is necessary to prevent rain on one side. During rainfall, arch sheds with relatively low terrain are easily flooded with rainwater from the area, leading to severe outbreaks of some diseases. Some vegetable farmers decide not to remove the film and release the air when it rains, which can actually prevent rainwater from entering. However, the heat and moisture in the greenhouse cannot be dissipated, and simply releasing a small amount of air from the top to cool down is far from enough.
