Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering pile foundation construction, in particular to an anti-blocking device for prestressed concrete pipe piles. Background Technique

[0002] A prestressed concrete pipe pile is a tubular slender member driven into the soil with a cross-sectional dimension much smaller than its length. The upper part of the pipe pile is connected with a bearing platform (beam) to form a pile foundation. Its basic structure is a prestressed concrete structure, which can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. After the top of the prestressed concrete pipe pile is installed, it is easy for soil or other substances to enter from the top of the prestressed concrete pipe pile. To prevent the prestressed concrete pipe pile from being blocked, an anti-blocking device needs to be used and installed at the top of the prestressed concrete pipe pile.

[0003] The Chinese utility model patent with the reference authorization publication number CN220686068U discloses an anti-blocking device for prestressed concrete pipe piles, which relates to the related technical field of civil engineering pile foundation construction. It includes two steel discs arranged oppositely, and the central axes of the two steel discs are collinear. A number of steel holes are evenly arranged around the central axis on the two steel discs. A column is concentrically arranged coaxially in the middle of the steel discs. The two steel discs and the column cooperate to form an I-shaped structure. A sponge is filled around the column at the middle position of the I-shaped structure. One end of the column penetrates through the steel disc and protrudes outwards. A small pier is concentrically arranged coaxially on the end face of the protruding column, and a pull ring is arranged on the small pier. A number of transverse brackets are arranged at equal intervals around the central axis on the side of the protruding column, all of which are arranged radially along the column and are clamped at the pipe orifice. This device filters water and blocks soil particles to prevent blockage and can be reused.
