Double Arch Tunnel Greenhouse

The Double Arch Tunnel Greenhouse is an upgraded tunnel-type agricultural planting facility developed on the basis of traditional single-tunnel greenhouses.Featuring a unique double-layer arch tunnel structure and double-film covering design,it combines structural firmness,excellent thermal insulation and low construction cost.This greenhouse is widely favored for off-season vegetable planting,seedling breeding,fruit and flower cultivation,especially suitable for cold regions,high-wind areas and zones with large day-night temperature differences.With simple assembly,strong weather adaptability and outstanding energy-saving performance,it has become an ideal low-investment and high-return commercial greenhouse for modern small and medium-sized farms.

Different from ordinary single-arch tunnel greenhouses,this model adopts an inner and outer double-arch overlapping structure to form an independent and stable tunnel space.The entire frame is made of high-quality hot-dip galvanized Q235 steel pipes,which effectively resists rust,corrosion and outdoor weather aging.The double-arch structural design greatly improves overall mechanical strength,significantly enhancing wind resistance and snow-bearing capacity.It can withstand harsh weather conditions such as strong seasonal winds,heavy snow accumulation and freezing temperatures,solving the problems of easy deformation and poor stability of traditional tunnel greenhouses.The standardized assembled structure allows fast on-site installation,flexible size adjustment and convenient daily maintenance.

Covered with professional double-layer agricultural plastic film,the greenhouse achieves balanced light transmission and environment optimization.The outer film is treated with UV anti-aging technology to resist long-term solar radiation,avoiding film cracking,yellowing and light transmittance attenuation.The inner film adopts anti-fog and anti-drip coating to eliminate condensed water dripping inside the tunnel,reduce crop fungal diseases caused by high humidity,and create a clean and dry growing environment for plants.The double-film collocation maintains high and uniform light transmittance,ensuring sufficient soft light irradiation,promoting efficient photosynthesis,and steadily improving crop yield and quality.

The core advantage of the Double Arch Tunnel Greenhouse is its superior thermal insulation and energy-saving performance.A closed air insulation layer is formed between the inner and outer arch films,which effectively isolates indoor and outdoor heat exchange.In winter,the air cushion layer locks indoor heat effectively,increasing the internal temperature by 4–8°C compared with single-layer tunnel greenhouses,greatly reducing heating costs and preventing crop frost damage.In summer,the double-layer structure slows down external heat conduction,avoids excessive indoor temperature rise,and reduces high-temperature stress on crops.This stable temperature regulation realizes energy-saving and low-consumption planting throughout the year.

This tunnel greenhouse supports flexible configuration of various auxiliary systems to meet diversified planting needs.It can be equipped with external shading systems,side ventilation windows,top natural ventilation equipment,fan and wet curtain cooling systems,rolling thermal insulation quilts,as well as automatic irrigation and fertilization devices.In winter,the thermal insulation quilt cooperates with the double-layer film structure to achieve super heat preservation;in summer,ventilation and shading systems effectively cool down the interior.The matched functional systems realize intelligent control of indoor light,temperature and humidity,completely breaking seasonal planting limits and achieving continuous off-season production.

With sturdy tunnel structure,excellent cold resistance,remarkable energy-saving effect and ultra-low comprehensive cost,the Double Arch Tunnel Greenhouse is widely used for vegetable planting,strawberry and grape cultivation,flower planting,seedling nursery and medicinal plant cultivation.It provides a cost-effective and high-stability planting solution for agricultural investors and individual growers,and remains one of the most practical and widely promoted greenhouse types in modern facility agriculture.
