Chinese fir piles are often used in river piling construction or as support poles. When piling in rivers, the construction of fir piles often encounters various problems due to changes in the underwater environment. Therefore, fir piles used for river piling can be used underwater. How many years has it been used? Let’s follow the editor to find out.

Because fir piles do not have very good performance in underwater construction, the Hakka people have a saying, "A fir on land lasts for a thousand years, and a pine under water lasts for ten thousand years." This means that a fir will not rot for a thousand years if placed in a ventilated place, but a pine will not rot if it is immersed in water. The Hechang pine wood piles themselves are rich in rosin, which can prevent them from being damaged by groundwater and bacteria. The pine wood buried in the groundwater level can last for a long time, so it can be used as a slope protection for river projects. Piles can also be used as river channel piles. In some projects that are completely submerged in water, fir piles can last for decades, but pine piles can last for hundreds of years. They will not decay and can be used as a choice for water conservancy projects. At the same time, its price It is also very cheap. Most construction projects will choose this material, which is a more cost-effective choice.

Chinese fir piles can be used as slope protection piles in river projects or as river channel piles. However, if you want the fir piles to maintain a longer service life in the water, you can use some preservatives before entering the water, but this increases the cost, so we do not The Tai advocated using fir wood piles to drive them into the water.

Pay attention to avoid cracking of fir piles. Once large cracks appear on fir piles, their performance will be affected to a greater or lesser extent during use. Therefore, be careful not to cause fir piles to appear before piling. If there are cracks, try not to use them.
