In spring, strong winds are frequent and the wind direction changes frequently, which has a greater impact on the shed. Therefore, in spring, the facilities should be repaired and fixed in time to improve the resistance of the shed to strong winds. Greenhouse reinforcement can start from three aspects:
1. Strengthen the fixation of the cover
When the roof covering is rolled up, it is located at the highest point of the roof of the roof, especially when the air outlet is higher, the covering is at the top of the rear roof triangle, so it needs to be fixed both front and rear.
2. Strengthen the fixing of the roller blind
The most affected by the windy weather is the strut-type roller shutter machine. The first is to fix the pole base. The second is to fix the poles and struts with iron wires or ropes, so that there is tension in the four directions, which can improve the resistance to strong winds.
3. Repair damaged shed film
If the shed film is damaged, it will cause an imbalance in the pressure inside and outside the shed. When the shed film is damaged, it is the south wind that most affects it. When the shed film is damaged or the tuyere is not closed, the air pressure inside the shed is likely to be higher than the air pressure outside the shed, so that it is easy to rupture the shed film. For the front face of the big shed, especially the place where the rolling machine is running, the damage of the shed film is usually serious. The canopy film can be repaired by internal and external clips. The outer side can be repaired with a block film with adhesive, and the inner side can be covered with a layer of mulch film by using the dew on the film.
