[0002] Prefabricated pipe piles are a type of tubular support structure made of cement. The manufacturing process of the pipe piles requires the use of steel strands and cement materials, which are then welded and mixed to form the final pipe piles.

The utility model has good pull-out resistance and can speed up construction progress.

[0004] However, the existing structure still has the following problems: when the existing pipe piles are manufactured, they are first welded together by iron wire and steel strands, and then the steel wire mesh after the steel strands are welded is placed in a mold, and then poured with cement to cover it, and finally rotated to form a cement column through centrifugal force. In order to lengthen the pipe piles, the existing technology uses steel strands to connect the formed pipe piles, and then pours cement again to connect the pipe piles to extend them. However, after this operation, the supporting force inside the pipe piles is not enough to support the load-bearing capacity after the multiple pipe piles are connected, especially the force-bearing capacity at the connection is weaker than that of other parts of the pipe piles, resulting in the long pipe piles after the connection are not strong enough and easy to break.
