Basic form:
1, hammer into the pile
It is convenient and quick to measure the distance at the installation site and directly use the pile driver to drive the column into the ground. Geological soil testing is required prior to installation to determine the appropriate penetration depth.
The following profiles are suitable for hammering into piles, depending on the actual situation:
advantage:
Fast and adaptable;
High cost performance;
Not subject to seasonal temperatures, etc.;
The pile is easy to remove and does not affect the reuse of the installation site.
2, spiral pile
When the installation site is too hard, or there are too many gravel, it is not convenient to directly hammer the column into the ground, you can use the spiral pile. Screw the screw-in steel into the ground and secure the column to it.
advantage:
The solar ground mounting on this way is adaptable, flexible and diverse;
Not subject to seasonal temperatures, etc.;
The pile is easy to remove and does not affect the reuse of the installation site.
3. Precast cement foundation
If the installation site is not suitable for plug-in piles, you can choose to make the cement foundation. The brackets are placed on the cement foundation and bolted.
advantage:
Good strength and high precision;
Adaptable to the ground.
4. Direct cement pouring
Another form of cement foundation is to directly pour the bracket and cement together. This way. Compared with the above, the time for fixing the bolt connection is omitted, but the positioning accuracy of the support column is required when pouring.
advantage:
The solar mounting structures are good strength and high precision;
Adaptable to the ground.
