Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pipe piles, in particular to a prestressed concrete pipe pile anti-clogging device. Background Art

[0002] Concrete pipe piles, especially prestressed high-strength concrete pipe piles (PHC pipe piles), are hollow cylindrical concrete precast components made by prestressed centrifugal forming technology. The standard section length of this type of pipe pile is usually 10 meters, the diameter can range from 300 mm to 800 mm, and the concrete strength grade is not less than C80. Concrete pipe piles have many advantages, including high single pile bearing capacity, wide application range, reliable pile sinking quality and low engineering cost. They can adapt to different geological conditions, and have fast construction speed, high work efficiency and short construction period. Therefore, they are widely used in many engineering projects. When using concrete pipe piles, the soil falls into the pipe due to mechanical vibration, causing the pipe piles to need to be desilted later, so concrete pipe pile anti-clogging devices are needed.

[0003] For example, the utility model with publication number CN220686068U discloses a prestressed concrete pipe pile anti-clogging device, including two steel plates arranged opposite to each other, and the middle axes of the two steel plates are in line, and a number of steel holes are evenly arranged on the two steel plates around the middle axis, and a column is concentrically and coaxially arranged in the middle of the steel plate, and the two steel plates and the column cooperate to form an I-shaped structure, and the middle position of the I-shaped structure is filled with sponge around the column, one end of the column passes through the steel plate and protrudes outward, and a small pier is concentrically and coaxially provided on the end face of the protruding column, and a pull ring is provided on the small pier, and a number of cross brackets are evenly spaced around the middle axis on the side of the protruding column, which are all arranged radially along the column and clamped in the pipe mouth.

[0004] When blocking the soil, sometimes soil will enter the interior of the concrete pipe pile through the gap. The soil entering the concrete pipe pile cannot be pushed out, resulting in the formation of silt inside the concrete pipe pile, which affects the later use of the concrete pipe pile. Therefore, a prestressed concrete pipe pile anti-clogging device is proposed to address the above problem. Utility Model Content
