Construction method of sunlight greenhouse

Abstract

The invention discloses a construction method of a sunlight greenhouse, comprising the steps of construction of an eastern gable wall, a western gable wall, a rear wall and a ceiling. The construction of the rear wall comprises the following steps: a right triangle support composed of an upright column and an inclined column is embedded at intervals of 1.8-2m in the east-west directions; the inclined column is intilted southwards, wherein, the distance between the bottom end thereof and the bottom end of the upright column is 1.5-1.7m; and the over-ground height of the upright column is 4-4.2m and the underground embedding depth is 0.5-0.8m. The wall is made of a two-mat and three-film structure, i.e. the inner and outer surface layers of the wall are made of polyethylene anti-drop film; two straw mat layers with the thickness of 78cm are arranged in the middle; one polyethylene anti-drop film layer is arranged between the two straw mat layers; and a metal net is arranged on the outersurface of the polyethylene anti-drop film in the inner surface layer. In addition, a right triangle support composed of an upright column and an inclined column is embedded on the eastern gable walland the western gable wall at intervals of 3.5-3.7m in the south-north directions; and the ceiling is constructed according to the current sunlight greenhouse. The construction method has the advantages that the occupied areas of the rear wall and the gable wall are reduced, the greenhouse is conveniently disassembled and removed, the construction height of the greenhouse is improved and the greenhouse span is increased, thus being more favorable for cultivation of fruit trees.

Description

technical field [0001] The invention relates to a solar greenhouse construction method. Background technique [0002] At present, the back wall and gable wall of the semi-arch solar greenhouse are mostly constructed of mud piles or masonry materials. In order to resist rain and water bubbles, the foundation needs to be 0.5m above the ground. When the wall is built with bricks, the inner brick wall is 24cm, the middle insulation interlayer is 12-20cm, and the outer brick wall is 24cm thick, which makes the wall thickness between 60-70cm; The foot mud stack has a bottom width of 1-1.2m and a top width of 0.8m. Therefore, the land use rate is low, the soil structure is damaged, and it is easy to wash and collapse in summer, and it is repaired every year. The construction period is long, and the height of the wall is limited, generally 1.8-2.2 meters, which is not suitable for the cultivation of fruit trees. At the same time, since the top of the back wall of the above-mentio...

Problems solved by technology

Therefore, the land use rate is low, the soil structure is damaged, and it is easy to be washed and collapsed in summer. It is repaired every year, the construction period is long, and the height of the wall is limited, generally 1.8-2.2 meters, which is not suitable for the cultivation of fruit trees.

At the same time, since the top of the back wall of the above-mentioned solar greenhouse is mostly equipped with a back slope extending forward and upward about 1.7-2m, its elevation angle is generally 35°-45°, and there is a problem of shading some areas in the greenhouse
