Cement Base

The depth of the foundation can be relatively shallow, but the amount of excavation and backfill is large, and the amount of
concrete is relatively large.

This kind of foundation form is mostly used in poor foundation bearing capacity, suitable for flat single-axis tracking
photovoltaic brackets with relatively flat sites and low groundwater levels, and high requirements for uneven settlement.

Precast pile foundation

Prefabricated pile is made in the factory or construction site of various materials, various forms of pile (such as wooden pile,
concrete square pile, prestressed concrete pipe pile, steel pile, etc.), the pile is driven, pressed or vibrated into the earth
with pile driving equipment. Precast piles are mainly concrete precast piles and steel piles in the construction field of China.

It can be made in batch, the construction speed is fast, the construction does not exist to fill the excavation, only a simple
field level. However, when the pile body is squeezed into the soil by static pressure or hammer equipment, the pile body is easy
to fracture, and the top of the pile needs to be reinforced by steel mesh, which increases the cost and the perpendicularity is
not easy to ensure.

It is widely used in silty soil, cohesive soil, fill soil, collapsible
loess and so on.

Hammer the pile into the ground

The use of a pile driver to directly drive C-shaped steel, H-shaped steel or other structural steel into the ground, this
installation method is very simple, but the tensile performance is poor.

Fast speed, strong adaptability;
High cost performance;
Not subject to seasonal temperature and other restrictions;
The ground pile removal is convenient and does not affect the reuse of the installation site.

It is difficult to drive piles in hard soil; It is easy to destroy the
galvanized layer when driving pile in the area with more
gravel. Corrosion resistance is
poor in saline-alkali areas.

Ground Screw

After the 1880s, screw pile has been widely used in the United States, Australia and Europe as an alternative pile with unique
advantages, which can meet various engineering requirements such as compression, withdrawal and horizontal force resistance.

The utility model relates to a pipe pile or pile of metal or non-metal materials with spiral blades, which is screwed into the
ground by special equipment, and the top of the pile is connected to the load. The utility model has the advantages of fast and
convenient construction, greatly shortening the construction period.
