Clear UV Treated Film Anti Rusted Mental Structure Tunnel Greenhouse
Tunnel Greenhouse Introduction:
High tunnel greenhouse is a simple and practical cultivation or breeding equipment, easy to construct and easy to use. Tunnel greenhouses are widely used in the cultivation of vegetables, fruits and flowers. The tunnel greenhouse can provide suitable light, humidity and temperature conditions, increase production and resist natural disasters. It can advance or postpone regulations to ease the contradiction between regulations and requirements.
Tunnel Greenhouse Component:
1. Steel structure
The main galvanized frame(The main column according to the wind load and snow load).
The greenhouse film (PE, PVC, EVA, PO) has different thickness (from 80 micro to 200 micro).
3. Ventilation system
There are two type, they are mannual and motor ventilation. Our standard ventilation system is on both sides, we can also provide roof ventilation for choice.
Standard greenhouse door is sliding door.
Tunnel Greenhouse Overview:
The plastic greenhouse is a single-span structure with small width and long length. In the selection of greenhouse structure, the planting mode of indoor crops must first be considered, and it must also be adapted to the planting conditions of this narrow and long area. From the analysis of structural forces, the lateral wind resistance of the greenhouse is strong, but the longitudinal wind resistance is weak. Therefore, the wind resistance of the two ends of the shed head (gable wall) column in the greenhouse design will directly affect the wind resistance of the greenhouse structure. In order to strengthen the overall wind resistance of the greenhouse, it is generally required to have diagonal supports at both ends of the greenhouse to support the top of the gable column. In addition, the foundation should be firmly fixed to each arch. The arch without foundation should be firmly anchored by screw anchors. Fixed in the ground soil.
Tunnel Greenhouse Feature:
The plastic greenhouse has high light transmittance, and the temperature rises quickly under sufficient light conditions. Usually, it can maintain an indoor and outdoor temperature difference of more than 10 ℃ during the day. But at night when there is no auxiliary heat source such as the sun's radiation, the temperature drops very quickly. By the early morning, the indoor temperature is basically the same as the outdoor temperature. If it is a clear night, the indoor temperature in the early morning will even be lower than the outdoor temperature. This is called a greenhouse. The phenomenon of "inverse temperature difference". Special attention should be paid to the prevention of this inverse temperature difference in production management.
Tunnel Greenhouse Advantage:
The main advantages of plastic greenhouses are convenient construction and low cost. Generally, the film is changed in the same year, the indoor lighting is good, the roll film opens the window, the natural ventilation effect is good, and the north cannot be produced through winter.
