Example Embodiment
[0016] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0017] As shown in the figure, the prestressed steel-cylinder concrete jacking pipe includes an outer ring reinforced concrete 2 cast outside the concrete pipe core 9, and the socket end surface of the concrete pipe core 9 is flush with the bottom end surface of the outer ring reinforced concrete 2 When the upper end of the outer ring reinforced concrete 2 is poured, it exceeds the concrete top surface of the outer part of the steel tube at the socket end of the concrete core 9 and covers it to form a complete plane. When the pipe is pushed in, the pushing force can be evenly distributed to The outer ring reinforced concrete 2 and the outer part of the steel cylinder of the concrete pipe core 9. There are embedded wire anchors 3 at both ends of the concrete pipe core 9 to fix the prestressed steel wire 1, which is fixed at both ends of the outer wall of the outer r...
