This topic addresses the conditions under which pile foundations are applicable, as explained by the pile driver manufacturer. Pile foundations are a common foundation form, generally consisting of piles and a cap connected to the top of the piles. Due to their high bearing capacity, low settlement rate, small and uniform settlement, and ability to withstand vertical loads, horizontal loads, uplift forces, vibration, or dynamic effects, pile foundations are suitable for situations where natural foundation shallow foundations cannot meet the requirements, have excessive settlement, or insufficient stability. Let's discuss the conditions and scope of application for pile foundations.

1. Strict Tilt Limitations for High-Rise Buildings and Structures:

Pile foundations are used where high-rise buildings and structures have strict tilt limitations.

2. Excessive Load in Building Warehouses:

When the load in building warehouses is too large, excessive settlement of the foundation can cause damage to the building.

3. Establishment of Foundations for Precision Equipment and Power Machinery:

There are strict requirements for settlement, settlement rate, and allowable amplitude for foundations of precision equipment and power machinery.

4. Large Building Loads on Weak and Uneven Shallow Foundations:

When building loads are large and the shallow foundation is weak and uneven, pile foundations are needed to transfer the load to deeper soil layers if the natural foundation has excessive settlement.

5. No Excessive Settlement Allowed for Important Buildings:

Important buildings do not allow for excessive settlement, thus requiring pile foundations.

6. Heavy-Duty Cranes in Single-Story Industrial Buildings:

For single-story industrial buildings with heavy-duty cranes, large loads, compact foundation bases, and significant ground loads may cause substantial foundation deformation, necessitating the use of pile foundations.
