Plastic greenhouse

Film multi-span greenhouse foundation and main skeleton

1.Greenhouse base

Considering the factors of heat preservation, economy and beauty of greenhouse, according to the requirements of soil endurance, groundwater level and design load, to avoid uneven settlement of greenhouse, to prevent column distortion and shear deformation ,240 mm of reinforced concrete ring beam is used around the greenhouse. Outside the wall skirt to do 0.5m wide scattered water, gable plus drainage ditch, foundation buried depth of 1.0 m( tentative, according to the actual situation value is greater than the thickness of frozen soil layer). The indoor column of greenhouse adopts 220*220 mm reinforced concrete independent foundation, the buried depth of foundation is 1.0 m( tentative, according to the actual situation), the top of the foundation is pre-buried steel plate or anchor bolt, and the upper steel column  welded or bolted. The elevation of the embedded parts on the strip foundation and independent foundation is 5‰; in the north-south two-way looking for slope, reference to the detailed in the elevation schematic in the foundation plan.

Geological data: this design foundation bearing capacity standard value fka≥100kPa, after the construction slotted must be by Party A, the construction unit and the local geological department in accordance with the relevant construction code inspection slot, if not in accordance with the design must notify the relevant designers to negotiate to resolve.
