  0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Foundation is the foundation of a building, it is related to the stability, wind resistance and earthquake resistance of the whole building. Today we introduce to youGlass greenhouse constructionHow to do the foundation part, and the matters needing attention during the construction of the glass greenhouse foundation.

  0010010 nbsp; {{1}} nbsp; {{1}} nbsp; 1. Preparations for foundation construction of glass greenhouse construction

First of all, the investigation and analysis of the natural conditions should be carried out. The main contents of the investigation and analysis of the natural conditions in the construction area include regional level points and elevations; geological structure, the nature and type of soil, the bearing capacity of the foundation soil, and the earthquake level. Familiar with the construction content of civil engineering, and do well in water supply, electricity supply, smooth roads and leveling before construction.

The basic part of the glass greenhouse is divided into a single point foundation and the surrounding strip foundation part. The base position is the load-bearing column part, which mainly carries the IDE's own weight of the greenhouse and various external loads on the roof of the greenhouse. The surrounding strip foundation is also called the surrounding ring beam, which is mainly the load bearing side glass load and wind load. The contact area with the ground is large, so it can enhance the anti-settlement of the glass greenhouse as a whole.

   3. The pre-buried depth of the glass greenhouse construction foundation

Under the premise of meeting the foundation stability and deformation requirements, the foundation should be buried as shallow as possible. When the bearing capacity of the upper foundation is greater than the bearing capacity of the lower foundation, the upper soil body should be used as the bearing layer. In addition to the rock foundation, the depth of the foundation should not be less than 0. {{1}} meters, the foundation should be buried on the groundwater level; when the groundwater level is buried below the groundwater level, measures should be taken to ensure the foundation during the construction process No interference; measures should be taken when the local foundation is buried on a soft rock layer. After excavating the foundation pit, the cushion layer should be laid in time. The depth should not be larger than the original greenhouse foundation. When the burial depth is greater than the original greenhouse foundation, a certain clear distance should be maintained between the two foundations. This value should be determined according to the load and soil conditions. In general, the height difference between two adjacent foundations is 1-2 times. When the permafrost layer is deep (> 1. {{1}} meters), the foundation depth can be designed to be 1 0-20cm above the permafrost layer, saving investment. For indoor column foundations or wall foundations, it is generally believed that the frozen soil will not appear during winter greenhouse operation, and the foundation depth is not affected by the frozen soil depth, and indoor crops should be considered. Cultivation and reaching the requirements of the foundation bearing layer can generally be buried below 0.8-1 meters underground.
