What is the use of threaded piles in building high speed rail

The threaded piles play a role in the construction of high speed rail by supporting, dispersing loads and waterproofing.

The threaded pile plays an important role in the construction of high speed rail. First of all, threaded piles can be used as the foundation support of high-speed rail lines. They are installed underground, and by connecting closely with the ground, they increase the stability and firmness of the line and ensure the safety of the train when running at high speed. Secondly, threaded piles are also capable of dispersing and transferring the loads generated when the train is traveling. High-speed trains usually have large weight and running speed, which requires high load on the line.

Threaded piles can disperse the impact of the load on the line and ensure the stability and durability of the line by bearing part of the load and transferring it to the underground. In addition, the threaded piles can also prevent the impact of groundwater level changes on the line. High-speed rail construction usually needs to cross the underground water layer, threaded piles can form a waterproof barrier by forming a waterproof barrier underground to prevent the impact of changes in groundwater level on the line, to ensure the safety and stability of the line.

Overall, threaded piles play the roles of support, load dispersion and waterproofing in high-speed rail construction. They are an important part of the high-speed rail line and are of great significance in ensuring the safe operation of high-speed rail.

Applications of threaded piles

1, Foundation treatment. Screw pile can be used in foundation reinforcement and treatment works. By driving the threaded piles into the ground, the bearing capacity and stability of the foundation can be increased, and the settlement and deformation of the foundation can be avoided.

2. Construction engineering. Threaded piles are often used in the foundation bearing aspect of construction engineering. They can be used as load-bearing support for buildings, transferring gravity to deeper soil layers.

3, Bridges and elevated roads. Threaded piles are widely used in the construction of bridges and elevated roads. They can be used as the foundation of bridge piers or support structures, providing sufficient bearing capacity and earthquake resistance.

4, Excavation and pit support. Threaded piles can be used as temporary or permanent support structures during excavation and pit excavation to ensure the stability of the excavation surface.

5, Coastal and water conservancy projects. Threaded piles can be used in the construction of dykes, wharves and facilities in coastal and water conservancy projects. They can be installed underwater as part of a revetment or breakwater.
