Detailed explanation of multi-span greenhouse construction technology
The construction of multi-span greenhouses is like building a house, except that the greenhouse is the growth space for plants, and the investment in the greenhouse is relatively large, so we need to do related work.
1. Site selection: The site selection for the construction of multi-span greenhouses should be selected in a place with flat terrain, fertile soil and deep soil layer; good lighting and ventilation conditions; convenient irrigation and drainage and good water conservancy conditions.
2. Construction of the wall: When building the wall, first use a bulldozer to compact the bottom of the wall (the north-south width is required to be between 6-8 meters) to prevent the foundation from sinking; in the second step, use an excavator to load the soil, 70 cm each time For thick loose soil, use an excavator to roll back and forth 2-3 times; use a bulldozer to compact the top of the wall.
3. Cutting the wall: When cutting the shed wall with an excavator, there must be a certain inclination, the top is narrow and the bottom is wide, and the inclination is 6-10 degrees.
4. Leveling the bottom of the shed: Use the excavator to level the bottom of the shed, and then flood the shed with large water, which is conducive to burying the column to prevent the column from sinking.
5. Adding columns: In order to improve the pressure resistance of the vegetable greenhouse, two rows of columns should be added in the greenhouse during construction, namely the rear column and the front column. The rear pillars are made of weighted pillars with a height of 5.5 meters (buried 50 cm below), and the front pillars can be used as ordinary pillars of 2 meters.
6. Pull the shed surface steel wire: The shed surface steel wire arrangement should be denser to increase the compressive capacity of the shed surface. All the steel wires on the shed surface are fixed on each steel frame with iron wires to increase the firmness of the steel frame.
