The most widely used form of foundation for ground-mounted photovoltaic power plants and the key factor affecting the stability of photovoltaic supports.
1. The most widely used form of foundation for ground-mounted photovoltaic power plants: the ground has a complex layered structure, the parameters of each layer are different, and each layer is not evenly distributed. piles The theoretical calculation formula can only calculate approximate values for initial budgeting. In order to more precisely test the bearing capacity of helical piles, pull-out tests are carried out.
2. Key factors affecting the stability of PV supports: In order to evaluate the tensile properties of cast-in-place PV support piles, a pullout test should be performed on the cast PV support. -place stakes.

Desert photovoltaic piles are high-strength composite desert photovoltaic piles developed for deserts, beaches, saline and alkaline lands and geological environments where groundwater seepage is likely to collapse. It is acid resistant. The advantages of alkali, long life and ease of construction completely solve the shortcomings of traditional spiral steel photovoltaic installations which are easy to corrode and the construction of cast-in-place concrete piles is difficult and expensive . improves the quality of the photovoltaic support system.

How to use metal stakes

How to use metal stakes for fences
For fences< /p>
Metal ground stakes
are generally used for fixing and tightening metal fence nets,
for fixing ,
to prevent them from breaking. by livestock such as cattle and sheep,
p>
Or it may be damaged by catastrophic weather conditions, forcing cattle and sheep to cross the border and and foreigners to enter at will, causing unnecessary losses.
Usually you can use a hammer to hit the positionn upper square of the pile to the ground, depending on the geological conditions of the ground. Hit
8
to
10
to make drive the stakes into the ground and secure them.
When using,
Please note that
Always pay attention to the condition of the ground where the stake is inserted,
< p>avoid it from falling to the groundp>
There are stones that block the path of the piles in the ground,
in order to prevent the Piles do not penetrate the ground smoothly,
and cause damage to the piles.
At the same time,
should also pay attention to the softness and hardness of the ground
to avoid soft ground causing poor reinforcement performance.

How to use spiral stakes
Screw stakes
are usually used to reinforce tents in sandy areas .
p>
Prevent the tent from being blown away by the wind.
At the same time, the spiral pile has a meiltheir gripping capacity than the general oblique pile in sandy and soft soils
.
Usually you need an iron rod of about
1
cm in diameter, inserted into the small hole at the top of the stake in opposite directions, and then
Turn the stake clockwise until the spiral part penetrates the sandy soil.
Note that
screw piles cannot be used in hard ground conditions
to avoid a decrease in work efficiency.

How to use metal wooden leg protection stakes
Metal wooden leg protection stakes
Used to protect wood The wooden support legs of the appliance prevent damage during use and extend the life of the wooden appliance.
When using,
you should choose size A wooden foot protection stakesppropriate
Place the wooden leg protection stakes on the legs of the wooden appliances
Insert it all the way,
then tighten it with wood screws and you can use it.

processed from iron rod.

Processing technology of metal piles
Metal piles
Generally, they are cut, bent, welded and stripping, electroplating, shaping and other processes can produce qualified metal piles. Among them, pickling and electroplating is an important anti-corrosion treatment process, which directly affects the service life of metal piles.
3
Factors affecting the service life of metal piles
The level of metal processing determines didirectly the lifespan of the metal piles, such as the quality of the iron metal selected, the quality level of the welding points
whether there are blisters, false welds, peeling and the thickness of welding points will all affect the future service life and further processing of metal piles p>and the quality of electroplating,
such as the electroplating time,
the quality of surface treatment Good
Good or bad, all affect the quality of anti-corrosion treatment of metal piles. In most cases, the plastic reshaping process aims to improve the appearance of the pile.
The environment and method of use also affect the lifespan of metal piles, such as soil acidity and alkalinity, whether the operation is appropriate
Improper use,
will damage the surface of metal piles,
will damage the metal protective layer,
will lead to gold.
p>
Corrosion of piles is accelerated and their lifespan is reduced.
Typically, metal piles can be used
8 to 10
80% of the time
years. The supporting foundation of the photovoltaic power plant project uses spiral piles and cast-in-place steel tube piles, 80% of which are spiral piles. The application of spiral piles can reduce project construction costs and shorten the construction period of photovoltaic power plants. refers to a type of photovoltaic power plant that uses solar energy and adopts a special power generation system composed of materials such as crystalline silicon panels, inverters and other electronic components, power generation system photovoltaic energy connected to the grid and providing energy to the grid.
