Construction design of new intelligent glass greenhouse
The design of new intelligent glass greenhouse construction refers to the greenhouse with glass as daylighting material. In the cultivation facilities, the new intelligent glass greenhouse construction design as the longest life of a method, suitable for a variety of areas and various climatic conditions. The new type of intelligent glass greenhouse construction design structure mainly includes greenhouse base, greenhouse steel structure and aluminum alloy structure, greenhouse base 1.5% . The foundation classification, the new Intelligent Glass Greenhouse Construction Design Foundation divides into the Independent Column Foundation and the Strip Foundation two kinds. The independent base can be used for inner or side columns, and the strip base is mainly used for side walls and inner partitions. 2. Before planning, the geological materials of the construction site should be carefully analyzed. First, the Geological Survey Statement of the site (for important large-scale greenhouse projects) ; Second, the construction site test (for general projects) ; third, based on experience and adjacent projects of the reference geological material (for small projects) . In the foundation planning, besides meeting the requirements of strength, it should also have the ability of meeting the requirements of stability and resisting uneven settlement, the foundation connected with the inter-column support should also have the satisfactory effect of transmitting horizontal force and spatial stability. The bottom of the greenhouse should be located below the frozen soil layer. The influence of heating on the frozen depth of the root can be considered according to the climate and soil condition. In general, the base of the root should be less than 0.5 m above the outdoor ground, and the distance between the top of the root base and the outdoor ground should be more than 0.1. Rice to avoid root exposure and adverse effects on culture. Except for special requirements, the distance between the bottom and top of the greenhouse and the indoor floor should be greater than 0.4 m.
