Abstract:
A corrugated pipe connection device for a continuous section at the top of a continuous T-beam pier, the device comprising a combined steel pipe telescopic device (19) and a corrugated pipe connector (18), wherein interiors of the combined steel pipe telescopic device (19) and the corrugated pipe connector (18) are hollow; the corrugated pipe connector (18) comprises a first clamping piece used for clamping a wall face of a corrugated pipe; a second clamping piece having the same structure as the first clamping piece is at one end of the combined steel pipe telescopic device in the length direction; at the other end is a telescopic steel pipe (12) which is telescopic in the length direction; and the telescopic steel pipe (12) is connected to the corrugated pipe connector (18). The device replaces a corrugated pipe between two T-shaped beams, thereby avoiding problems such as corrugated pipe breakage, slurry leakage and the like, caused by an original mode of construction. In addition, the device may freely stretch out and draw back according to the distance between the two T-shaped beams, and steel strands may be threaded by means of a strand threading machine.
