1. Cast-in-place reinforced concrete foundation: based on different basic forms, cast-in-place reinforced concrete foundation can be divided into cast-in-place concrete pile and pouring bolt.

Advantages: the concrete foundation of cast-in-place reinforced concrete has little soil, small amount of concrete, low cost and fast construction speed.

Faults: the construction of concrete foundation is easy to be restricted by seasonal and weather conditions. The construction requirements are high and cannot be adjusted once it is done.

2. Independent and strip concrete foundation

Advantages: the foundation of independent and strip concrete is based on the expansion of reinforcement, the construction method is simple, the geological adaptability is strong, and the foundation depth can be relatively shallow.

Disadvantages: large quantities of independent and strip concrete basic engineering, large amount of manual labor, large amount of excavation and backfill, long construction period, and great environmental damage.

2. Precast concrete hollow column foundation

The precast concrete hollow pillar is widely used in the substation of water - light complementary power plant and beach coating power station. At the same time, because of the advantage of the base height, it is also used for the mountain power station and the rural photocomplementary power station.

3. Ground power station - metal pile bracket

The application of metal pile bracket in ground power station is very wide, which can be divided into the base bracket of screw pile and the foundation bracket of impact pile.

4. Screw pile foundation support

The screw stents can be divided into flanges with flanges and the bracket of the spiral pile without the farrah plate. The leaf shape can be divided into narrow leaf continuous screw pile bracket and wide blade spacer screw bracket.

The spiral piles with flanges can be used for single column installation or double column mounting, while the spiral pile without the flange is generally only used for double column mounting.

The tensile strength of the wide blade spacer is better than that of the narrow impeller continuous type screw stents, and the wide blade interval type screw brackets should be given priority in the wind area.

5. Impact pile foundation support

Impact of pile foundation support, also called metal fibre rod foundation support, mainly using the driver directly to C steel, H section steel or other structural steel into the ground, the installation is very simple, but drawing resistance is poor.
