  • Patent number: 12351997
    Abstract: A corrugated pipe connection device for a continuous section at the top of a continuous T-shaped beam bridge pier. The connection device includes a combined steel pipe telescopic device and a corrugated pipe connector, the interiors being hollow; the connector includes a first clamping member for clamping a wall surface of a corrugated pipe; one end of the telescopic device is a second clamping member with the same structure as the first; the other end is a telescopic steel pipe which is telescopic in the length direction; and the telescopic steel pipe is connected to the connector. The device replaces a corrugated pipe between two T-shaped beams, thereby avoiding problems such as breakage and slurry leakage caused by an original construction mode. The device can stretch out and draw back according to a distance between the T-shaped beams, and steel strands can be stranded by means of a stranding machine.
