| description | The utility model discloses a prestressed concrete cylinder pipe (PCCP) convenient for outer layer concrete filling, which comprises a prestressed concrete cylinder pipe main body, a plurality of strength support rings are arranged in an inner cavity of the prestressed concrete cylinder pipe main body in a straight line shape, and a plurality of concrete support rings are arranged on the peripheral surface of the prestressed concrete cylinder pipe main body in a straight line shape. A plurality of concrete connecting holes are evenly distributed in the peripheral faces of the concrete supporting rings, and a plurality of concrete connecting protrusions are evenly distributed on the peripheral face of the prestressed steel cylinder concrete pipe body. According to the PCCP pipe facilitating outer layer concrete filling, the strength of the filling pipe is improved by arranging the concrete supporting rings and the strength supporting rings which are arranged in a crossed mode, the binding force between the fil |
