Fir wood piles are wooden piles made of fir. They are mainly used to deal with various soft soil foundations and reinforce river embankments. Fir wood piles usually also play a positive role in flood relief and disaster relief. When the temperature changes drastically, the size may change. But it can be ignored as a fir pile, so how do fir piles work? We will explain it in detail below:

The effectiveness of fir piles in flood prevention and disaster relief is mainly reflected in two aspects:

(1) Condensation of soft soil. The pile spacing of fir piles is relatively close and driven into the hard soil layer, which has an obvious effect on squeezing soft soil. On the opposite bank of the flood, it mainly plays the role of squeezing the dam body. It can also protect the impact of floods on the river bank. These effects of fir piles are very important.

(2) Fir wood piles have some unique properties when used for foundation treatment, as follows: high strength and low density, with the advantages of light weight and high strength; good elasticity and toughness, and can withstand impact and vibration; under appropriate maintenance conditions, It has good durability; the joint structure is simple and easy to process, and can be made into products of various shapes; fir wood piles have strong hygroscopicity and swelling and shrinkage properties. When dry fir wood absorbs moisture, as the absorbed water increases, The fir wood will expand in volume.

(3) The barked fir piles themselves have great friction. Fir piles are often used in flood relief and disaster relief. They have good anti-slip coefficients and dense pile spacing. They only need to be driven into the soil to a sufficient length and the pile tops are involved. Sandbags, rocks and gravel can very well increase the strength and shear strength of the dam body, making the fir piles, gravel, stones and sandbags form a whole. The strength of the flood control dam will be greatly improved.
