High-speed rail threaded piles are a pile structure used to fix the track in high-speed rail construction.
According to a query on NetEase, we learned that it is usually made of reinforced concrete or prestressed concrete and has a thread-like shape design that can be closely connected to the rails and play a role in fixing the track and supporting the roadbed. The shape of high-speed rail threaded piles is similar to long spiral nails. They are usually easier to install and disassemble than ordinary pile structures. They also have higher earthquake resistance and wind resistance, which can effectively improve the safety and stability of high-speed railways. High-speed railway threaded piles are usually installed on the roadbed of high-speed railways and run through the entire track system to form a solid support structure, which provides an important guarantee for the safe operation of high-speed trains.
The design and construction of high-speed rail threaded piles need to consider many factors, including geological conditions, bearing capacity, settlement control, etc.
