Abstract
Description
Technical Field
[0001] The present application relates to the technical field of foundation pipe piles, and in particular to a prestressed concrete pipe pile. Background Art
[0002] The main raw materials of concrete pipe piles include cement, sand, stone, water and steel bars. The production process includes steps such as raw material preparation, mold making, pouring concrete, and maintenance and demolding. Among them, mold making needs to be determined according to the design size of the concrete pipe pile. The mold generally consists of two parts, one is the outer mold of the pipe pile, and the other is the core mold of the pipe pile; concrete pipe piles can be mainly divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. Pre-tensioned prestressed pipe piles are a kind of hollow cylindrical slender concrete prefabricated components made by pre-tensioning prestressing technology and centrifugal forming method. They are mainly composed of cylindrical pile body, end plate and steel sleeve. The code name of prestressed concrete pipe piles is PC, the code name of prestressed high-strength concrete pipe piles is PHC, and the code name of thin-walled pipe piles is PTC. The concrete strength of PC piles and thin-walled pipe piles shall not be lower than C60, while the concrete strength grade of PHC piles shall not be lower than C80. In construction projects, when the geological conditions are poor and the bearing capacity of the foundation is small, pile foundations can be used to drive piles one by one into the ground, and the weight of the building above is transferred to the lower soil layer with high bearing capacity through the pile foundation. In addition, concrete pipe piles are also widely used in bridge engineering and tunnel engineering. For example, they are used as important supporting materials in bridge foundations, and have unique advantages in tunnel settlement treatment.

The connecting sleeve has no connecting hole treatment and is just a smooth plane that cannot be connected to other pipe piles. Some connecting sleeves have been connected, but the connection method is not stable and cracks often occur between the pipe piles. Utility Model Content
