Common raw materials of pipe piles are steel, concrete piles, reinforced concrete, wood and polyethylene.
1. Steel piles
The material of steel piles is mainly steel, which has the advantages of high strength, corrosion resistance and long service life. Steel piles are suitable for various complex geological conditions and also have high construction efficiency and control accuracy in construction. However, the price of steel piles is high, and anti-corrosion measures are required to extend the service life. There are various types of steel pipe piles, including LVT type, Spun Pile type, Spiral Welded type, etc., which can be used in various scenarios.
2. Concrete piles
Concrete piles are one of the most commonly used pile foundations. They are mainly composed of cement, sand, stone, water and other materials, and are made through a series of process processes such as mixing, pouring and curing. Compared with other types of piles, concrete piles have better bearing capacity and stability, and the construction is simple and low cost, so they are widely used in engineering.
3. Reinforced concrete piles
Reinforced concrete piles are based on concrete piles, and steel bars are added to increase their strength and stability. Reinforced concrete piles can be directly cast or prefabricated. It also has the advantages of insulation, vibration reduction and environmental protection. At the same time, it is easy to construct and can be connected by machinery. Reinforced concrete piles have a long service life and are suitable for the foundations of large buildings and important projects such as bridges, river embankments, and docks.
4. Timber piles
Timber piles are mainly made of wood materials. Their advantages are easy processing, adaptability to various complex geological conditions, and flexibility during installation. However, timber piles have the disadvantages of being easy to rot, bio-eroded, and flammable. They are easily damaged in a humid environment, so they need to be treated with anti-corrosion when used.
5. Polyethylene pipe piles
Polyethylene is a relatively new type of raw material for pipe piles. It is characterized by low cost, light weight, easy processing, light material, chemical corrosion resistance, and easy installation. Polyethylene pipe piles are mainly used in drainage and sewage pipes in the lower part of buildings in infrastructure projects.
Long-term protection measures for pipe piles:
1. Appearance inspection
After installing the pipe piles, check the appearance of the pipe piles frequently to ensure that there are no cracks, wounds or corrosion on the surface. If there are any problems, they need to be repaired in time. This is crucial to the protection of the pipe piles, allowing the pipe piles to withstand the load and the influence of the external environment for a long time.
2. Anti-rust treatment
Pipe piles are exposed in the soil for a long time and are more susceptible to rust, which affects their service life. Therefore, a series of anti-rust measures need to be taken. Usually, hot-dip galvanizing or spraying zinc anti-corrosion paint is used to firmly attach the protective layer to the surface of the pipe pile to prevent rust.
3. Spray anti-corrosion
Spray anti-corrosion is also a commonly used method in the long-term protection measures for pipe piles. Its main function is to prevent oxidation, corrosion and damage on the surface of the pipe piles. Commonly used spray materials include asphalt paint, epoxy resin and polyurethane.
4. Add a protective layer
In addition to the above measures, adding a protective layer is also one of the ways to protect pipe piles for a long time. Materials commonly used are fiberglass casing, polyethylene casing and other materials, which are put on the pipe piles to play the role of isolation, anti-corrosion and heat preservation, thereby increasing the service life of the pipe piles.
In short, there are many types of materials for pile foundations, and different materials are suitable for different engineering environments. Reasonable selection of materials is an important part of ensuring the quality and success of the project.
