Description
Technical Field
[0001] The utility model belongs to the technical field of PHC pipe piles, in particular to a PHC pipe pile plugging device. Background Art
[0002] PHC pipe piles, namely prestressed high-strength concrete pipe piles, are made by prestressed centrifugal forming technology and cured by steam at 10 atmospheres (about 1.0Mpa) and 180°C to form a hollow cylindrical concrete prefabricated component with a standard section length of 10m, a diameter of 300mm to 800mm, and a concrete strength grade of ≥C80.
[0003] As urban development moves towards coastal soft soil sites, soft soil foundation treatment is a top priority for projects. Since soft soil sites are often accompanied by silt underground, PHC pipe piles are mostly used for foundation treatment projects. PHC pipe pile foundation treatment is widely used for its reliable quality, fast construction, and excellent results. PHC pipe pile construction adopts the form of first sinking the pile and then excavating the whole. Since the bottom is closed with a pile tip, no slag and gravel will enter the pile during the sinking process. Since the upper end of the PHC pipe pile is open, the core of the prefabricated pipe pile is easy to enter slag and gravel during the excavation process.
[0004] The traditional method of sealing the upper end of PHC pipe piles is to use flexible materials for filling. Generally, the bearing capacity is insufficient and the sealing is not tight, which can easily cause the filling material to be pressed into the pipe piles, and debris and gravel will also enter the pipe piles, increasing the workload of subsequent hole cleaning and filling, thereby increasing construction costs and construction period.
