[0002] The prefabricated pipe pile is a tubular concrete pile made in advance in a factory or on site, mainly used in construction engineering. The prefabricated pipe pile can be divided into various types according to the pile diameter, pile length and use, such as prefabricated concrete pipe pile, prestressed concrete pipe pile, steel pipe pile, etc. This pile type is widely used because of its firmness, durability and fast construction speed, but it has a greater impact on the surrounding environment during construction. The commonly used prefabricated pipe pile includes concrete solid square pile and prestressed concrete hollow pipe pile.
