The different types of greenhouse

The foundation period of greenhouse construction is short, and the independent foundation or ring beam foundation is generally adopted. Specific choice of what form of greenhouse foundation, first of all, according to the type of greenhouse selection, secondly, according to the local terrain and climate conditions.

1, simple inserted arch shed. This kind of steel frame film greenhouse is generally inserted into the ground, that is, the greenhouse arch is inserted into the ground below 30-50cm, to enhance the stability of the shed surface. This shed load is small, winter is not generally produced.

2, solar greenhouse greenhouses. The solar greenhouse is generally divided into two structures: earth wall and brick wall. Among them, 1-1.2 meters are dug under the earth wall, and the masonry wall is built by rolling the earth on the spot. The embedded parts are embedded in the wall and welded to the main arch frame.

Brick wall solar greenhouse is generally made of 30-50cm brick base, the bottom of the base is rammed with 5cm notoginseng ash or plain concrete cushion, the upper part of the base is directly laid wall, and then the external cement mortar is plastered.

3, even thin film arch shed. This kind of greenhouse foundation generally adopts C15 or C20 pouring 40*40*60cm column type independent foundation, each main column below the masonry and reserved welding buried parts. High standard film shed design has a long service life, generally using C20 or C25 casting ring beam and independent foundation, foundation size is generally 40*40*80cm.

4, house greenhouse. Generally refers to the glass or sunshine board greenhouse, the greenhouse is all C20 or C25 ring beam and independent foundation casting, the service life is generally more than 20 to 25 years, the foundation pit depth of the greenhouse is generally 80-120cm. According to the local climate and geological conditions, 20cm below the frozen layer is generally appropriate, and 20-30cm deeper is appropriate in areas with heavy snowstorms in the northern region.
