What kind of wood are the river wooden piles on the bank protection?

1. Pine wood pile

Because pine wood is rich in rosin, it can well prevent corrosion by groundwater and bacteria. It has been widely used in water conservancy projects since ancient times. The famous water conservancy project Lingshan was selected into the 2018 (5th batch) World Irrigation Engineering Heritage List. The foundation of the canal is treated with pine wood piles.

2. Pine wood pile revetment

Pine wood piles have been used as a building material in water conservancy projects to this day. As people's requirements for water-friendly landscapes have increased, as a building material from nature, its use has also developed into a form of river bank protection, such as Hangzhou Xixi National Wetland The rivers in the park mostly adopt the form of pine wood pile bank protection. Although pine wood piles are said to be "waterlogged ten thousand year old pines", they are only suitable for work below the groundwater level. For pine wood piles located in water level fluctuation areas, their junctions are relatively small. It is easy to rot. Therefore, the pine pile type bank protection will rot after it is built and used for a period of time. In addition, the gnawing of underwater herbivorous fish will accelerate the rot. Usually, it needs to be repaired and constructed repeatedly every few years, which has poor economic benefits.

3. Centrifugal imitation wood pile

Today we introduce a kind of prestressed concrete centrifugal imitation wood pile, which uses corrosion-resistant high-performance concrete as the main material, combined with the prestressed concrete pipe pile technology, and is centrifugally formed. The surface of the pile body is treated with wood grain, which looks different from the traditional pine wood pile. It can replace traditional pine piles as river bank protection materials.

4. Main features

1. Good mechanical properties

The pile body is made of prestressed steel bars and steam cured. The pile body has high strength and good bending and crack resistance.

2Good environmental performance

The pile body imitates wood realistically, which can reduce the use of wood and is environmentally friendly without losing appearance.

3 Strong durability

The pile body has strong impact resistance, is not easy to deform and discolor, and has good stability.

4Moderate cost

Compared with the traditional wooden pile structure, the price is relatively moderate (about 110 yuan per linear meter for a 200mm outer diameter model, for reference only). Due to its better durability and stability, it requires less maintenance in the future.
