Ground photovoltaic support foundation
Bore-in-place pile foundation: It is more convenient to form holes, the top elevation of the foundation can be adjusted according to the terrain, the top elevation is easy to control, the amount of concrete reinforcement is small, the amount of excavation is small, and the construction is fast. , little damage to the original vegetation. However, there are concrete holes and pouring on site, which are suitable for general fill, clay, silt, sand, etc.
Steel spiral foundation: easy to form holes, the top elevation can be adjusted according to the terrain, not affected by groundwater, construction as usual in winter climate conditions, fast construction, flexible elevation adjustment, suitable for The damage to the natural environment is very small, there is no excavation and filling works, the damage to the original vegetation is small, and no field leveling is required. Suitable for deserts, grasslands, tidal flats, next door, frozen soil, etc. However, the steel used is larger, and it is not suitable for strong corrosive foundations and rock foundations.
Independent foundation: strong water load resistance, flood resistance and wind resistance. The amount of reinforced concrete required is large, the labor is large, the amount of earthwork excavation and backfilling is large, the construction period is long, and the damage to the environment is large. It has been rarely used in photovoltaic projects.
Reinforced concrete strip foundation: This type of foundation is mostly used for poor foundation bearing capacity, suitable for areas with relatively flat sites and low groundwater levels, and requires more uneven settlement. High flat uniaxial tracking photovoltaic support.
Prefabricated pile foundation: prestressed concrete pipe piles with a diameter of about 300mm or square piles with a section size of about 200*200 are driven into the soil, and steel plates or bolts are reserved at the top to The front and rear columns of the upper bracket are connected, and the depth is generally less than 3 meters, and the construction is relatively simple and fast.
Bore-in-place pile foundation: low cost, but high requirements for soil layer, suitable for silt with a certain degree of density or plastic, hard plastic silty clay , it is not suitable for loose sandy soil layers, cobblestones or gravels with hard soil may not easily form holes.
Steel screw pile foundation: use special machinery to screw it into the soil, the construction speed is fast, there is no need for site leveling, no earthwork and no concrete, and the vegetation in the field is protected to the greatest extent. The height of the bracket can be adjusted according to the terrain, and the screw pile can be reused.
Flat Roof PV Support Foundation
Cement counterweight method: pouring cement piers on the cement roof, this is a common installation method, the advantage is stable and does not damage the roof waterproofing.
Prefabricated cement counterweight: Compared with the production of cement piers, it saves time and saves cement embedded parts.
