The construction of glass greenhouse should consider the influence of load and weather

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Large-scale multi-span glass greenhouse is one of the development trends of modern greenhouses, but the increase of single area will bring certain to the construction and design of greenhouse Difficulties. In the design, the influence of different loads and bad weather should be considered, and the entrance port of mechanical equipment and intelligent system should be reserved to make the production area larger.Glass greenhouse constructionAfter accurate accounting design, it can save energy for subsequent production and reduce operating costs.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1. Site selection

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The location of the glass greenhouse construction mainly considers the terrain and environmental constraints. In areas with seasonal winds in winter, try to build greenhouses in windward areas with mountains, windbreaks, or high-rise buildings. It also needs to consider factors such as traffic, terrain height differences, energy, and landscape location. Of course, the impact of natural disasters such as hail and earthquakes should also be considered.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (1) Try to avoid basic farmland and general farmland, and try to reduce the occupation of farmland by greenhouse construction.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (2) Try to choose a place close to the heat source, such as a thermal power plant. Operating costs.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (3) As close to the main marketing area as possible to reduce storage and transportation costs.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (4) The actual production of modern large greenhouses and greenhouses requires electricity. Therefore, the problems of power supply and wiring should be considered. We must strive to achieve convenient power supply, simple lines, and guaranteed power supply. When conditions permit, two-way power supply equipment or some power generation facilities can be configured for temporary emergency power consumption.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; (5) Try to stay away from the polluted area. If the soil, water and air in the greenhouse are polluted, it will bring potential hidden dangers to crop production and affect the health of consumers. Therefore, try not to build a greenhouse near the polluting factory, and pay special attention to the wind or the downstream of the river.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Second, the glass greenhouse construction greenhouse load

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Large glass greenhouse construction cost is higher. In order to ensure the strength requirements and temperature operation of the greenhouse, more consideration should be given to the loads that may be encountered during the operation of the greenhouse, and the calculations should be checked. In the design process, the roof load should consider the local wind load and snow load (including different crop planting methods and internal and external shading factors to calculate the load in the overall structure of the greenhouse). The wind load and snow load should be calculated according to the meteorological data on the construction site, according to the current structural codes in China, and the upper loads such as the roof should be calculated based on the weight of the crop suspension, the weight of other equipment pipes and the upper limit snow cover.
