A greenhouse is one of the elements of a large number of personal plots. Such facilities may vary parameters, shape, material that is used for coating.
One of the varieties greenhouse designs is a tunnel greenhouse. It differs in a number of advantages and can be operated as warm, and in a cold season.
Distinctive features
In most cases the tunnel construction is covered plastic wrap which different high density and is able to withstand quite large loads. A tunnel-type greenhouse has an upper part that resembles a not very high curved arch.
This structure prevents the gradual accumulation of a large amount of snow precipitation on the surface of the greenhouse - he rolls down the sloping walls buildings.
In addition, a unique architectural solution allows you to provide indoors good lighting throughout the day, which contributes to more intensive growth of plants.
In addition, the frame of these greenhouses is made of high-quality metal alloy.
Due to this property in it can install all the necessary technical equipment and devices for additional lighting.
No less important feature of such a frame is that it provides constant ventilation with end vents, which are located in different places of the greenhouse.
However, it should be noted that make vents for ventilation on the side walls of the greenhouse is impossible because of the specificity of the structure.
This type of greenhouses has several design characteristics:
- Regardless of the size of the building must necessarily have an arched shape.
- Thanks to the arched top, tall plants can be planted not only in the central part, but also at the edges.
- Such constructions easy and quick to install and dismantled.
- Due to the arcuate surface, the frame is characterized by increased resistance to various weather conditions.

Preparatory work
As a rule, tunnel greenhouses are made in such a way that their width reached about ten metersand the height of the structure was about five meters.
Before you start building a tunnel greenhouse with your own hands, you need to choose the most suitable place for its placement. So, many experts recommend to give preference OK lit area with the most even surface.
As for the foundation, in this case, you can completely do without it. It is enough just around the perimeter of the future greenhouse to carefully lay out a wooden bar, to which the frame of the structure will be attached.
Highly it is important to use cantpre processed special antiseptics - This will protect the material from gradual destruction as a result of interaction with various external factors.

Do-it-yourself construction
Tunnel type greenhouses can be built in several ways. However, the simplest and fastest method of mounting this design is carried out in the following steps:
- First you need to dig into the ground rack around the perimeter of the building. The depth of the pits must exceed one meter.. If the racks are made of wooden beams, they are treated with an antiseptic preparation, and if they are made of steel pipes, they are covered with a thick layer of special polymer paint in order to prevent corrosion of materials.
For heavy structures is recommended to make shallow-depth strip foundation.
- The supports are amenable to concreting - the pits are tightly purchased with gravel and sand to a height of about twenty centimeters.
- Formwork is being madeAs a rule, from ruberoid.
- Racks for the future frame of the greenhouse are securely fastened.
- A construction frame is assembled, in which the pitch is equal to one meter. The distance between them should be the same.
- The first row of crossbars is installed at the height calculated according to the total height of the greenhouse. So, if the height of the greenhouse is three meters, then it should be located at a height of about 1.20 m from the ground. The second row of crossbars is mounted at a height of 2.40 m.
- At the very top usually fastens so-called ridge beam. Bars are interconnected with bolts or large nails.
- In one of the walls is a mount for the door.
- Are installed in parallel special window frames.
- Carrying secure shelter to the frame. To fix the plastic film, ordinary nails are suitable, and the glass sheets will have to be connected to the prepared structure with screws that are inserted into the holes made in advance.
Conclusion
Tunnel greenhouses are great option for home gardens. They have an original form and aesthetic appearance, so they will fit well into the overall design of the territory.
