How many years can fir piles in the river be used in the water? The hydraulic impact of the river bank slopes can easily cause soil erosion, especially when the river water rises sharply, it will cause the river bank slopes to collapse, causing river siltation and other problems. The slopes in the southern mountainous and hilly areas Corrosion is more serious, so fir piles can be used as slope protection piles in river projects, which have a good control effect on water and soil erosion.

1. How many years can a river fir pile be used in the water?

Chinese fir piles can be used as slope protection piles in river projects, and can also be used as riverbed piles. They are insect-resistant and anti-corrosion. Chinese fir piles can be completely sunk into the water. Chinese fir piles can last for decades without decaying and are important parts of water conservancy projects.

2. Introduction to the use of fir wood piles in rivers:

1. The river fir pile ecological bank protection includes a window frame structure, hedges, pebbles, and 4 piles around the window frame structure, which are driven straight into the river bank slope. The fir piles include load-bearing piles and positioning piles. The load-bearing piles are placed at 4 right angles of the window sash structure. Positioning piles are set between load-bearing piles, and branch fences are wrapped around the piles to form a structural grid.

2. By changing the cushion thickness, the thinner the cushion thickness, the higher the percentage of the load carried by the fir piles to the total load, and vice versa. Without the cushion, the effect of the soil between the fir piles cannot be exerted. The fir pile slope protection structure Generally, stone masonry, reinforced cement concrete pouring, or steel wire mesh or nylon rope mesh are used to mix straw bales, stones, and gravel into a dragon shape and stack them on rivers or hillsides. This method of slope protection is one of the existing technologies. Common types.

3. The fir pile slope protection structure consists of two bases arranged in parallel at high and low levels. An ecological cage is fixed at the bottom of the base. There is a slope between the ecological cages. The base contains concrete columns evenly distributed and pressed into the original soil layer. The concrete columns are equipped with Metal parts, with straight connection threaded holes on the top. The ecological cage uses a bamboo cage as the skeleton, and uses hemp rope to fix the hemp rope mesh bag and multiple ecological bamboo tube components that run straight through the bamboo cage inside the bamboo cage. The ecological bamboo tube components There is a layer of infill and bolts running through the bamboo cages are also placed around the structure.

4. In order to improve the shear strength, it is more important to make the fir piles form a whole and bear the sliding force together. The fir anti-sliding piles are in a bending state. The fir piles have high bending strength, especially the combination of multiple rows has a better effect. Conducive to bending.

The use of fir piles for slope management is actually an old method, but it has always been used precisely because of the charm of fir piles.
