The present invention relates to a tunnel type greenhouse capable of firmly supporting the lower part of the structure of the greenhouse preventing a heat exchange of the inner and outer temperatures of the greenhouse easily draining water generated inside the greenhouse to the outside of the greenhouse and effectively enabling ventilating, maintaining the inner temperature of the greenhouse, and blocking sunlight to the inside of the greenhouse. Two pipes are installed at a predetermined interval side by side by a medium of a connection port. Double greenhouse structures of which the upper part is formed into an arch shape and both sides are vertically formed are at an equal interval. A transparent film is installed on the greenhouse structure installed at an equal interval, and a sideward-open window is formed on each of both vertical portions. A reversed V-shaped ventilation unit protruding upward in the longitudinal direction of the tunnel type greenhouse is formed on the upper center forming the arch portion of the greenhouse. A upward-open window is formed on each side of the ventilation unit. An internal transparent film layer is formed on the inner upper part of the tunnel type greenhouse. the internal transparent film layer is installed to be divided into one internal transparent film layer and the other internal transparent film layer on both sides the upper center. A space is formed by the divided internal transparent film layers having different heights. A space opening window is installed in the space. Supporting bars supporting the upper tip ends of both internal transparent film layers are installed on the inner center of the double greenhouse structure at an equal interval.COPYRIGHT KIPO 2014본 발명은 온실골조의 하부지지를 견고하게 함은 물론, 온실 외부지온과 온실 내부지온과의 열교환을 차단하고, 또 온실 내부에서 발생되는 물을 온실 외부로 용이하게 배수시키며, 온실 내부의 환기와 보온 및 차광을 효과적으로 할 수 있도록 한 터널형온실에 관한 것으로, 그 구성은 연결구를 매개로 2개의 파이프를 일정간격 유지되게 나란히 설치하되 상부는 호형이고 양측은 수직으로 형성시켜 된 2중 온실골조를 등 간격으로 설치하고, 상기 등 간격으로 설치된 온실골조에 투명필름을
