Usually when the foundation bearing capacity is insufficient and the foundation is not used to be directly excavated (such as quicksand, silt, swamp, etc.), we need to use pine piles to reinforce the soil. The load is transferred through the pine piles to ensure the buildings above. It will not be deformed or damaged due to uneven settlement of the foundation. The strength and deformation resistance of pine piling wood are better than those of soil, which can reduce deformation and improve bearing capacity. So what is the principle of pine piles? Below You can follow the editor to find out more.

1. High strength and low density, with the advantages of light weight and high strength.

2. Good elasticity and resistance to impact and vibration.

3. Under appropriate environmental conditions, it has good durability.

4. The structure is simple, easy to process, and can be made into wood products of various shapes.

5. Pine wood piles have strong hygroscopicity and swelling and shrinkage properties. When dry pine wood absorbs moisture, the pine wood will expand in volume as the adsorbed water increases.

6. Because of the structural characteristics of pine wood, it has four strengths: tensile resistance, compression resistance, bending resistance and shear resistance;

7. The shortcomings of pine piles can generally be discovered by careful observation of the appearance. It is necessary to prevent the use of defective piles for important structures.

8. Pine wood piles are rich in resin and have better anti-corrosion properties than most woods, making them suitable for piling in water.

In addition, fir piles are light in texture and relatively soft, but have fewer nodules and beautiful appearance. The material is not easy to deform and has low oiliness, so it is suitable for river piling construction. The texture of fir is not only lighter than that of pine, but also softer and knottier than pine. It has fewer scars and is less oily than pine. Fir is suitable for river piling, while pine is more suitable for various structural wood piles.
