Concrete leading-in device for concrete jacking construction and using method thereof

The invention discloses a concrete leading-in device for concrete jacking construction and a using method thereof. The concrete leading-in device comprises a baffle, a clamp and a U-shaped steel bar clamp, wherein the clamp consists of a semi-circular steel pipe hoop and a steel pump pipe welded to the rear end of the semi-circular steel pipe hoop. Bolts matched with bolt holes formed in symmetrical planes of two ends of the semi-circular steel pipe hoop in use are arranged at two ends of the U-shaped steel bar clamp. The using method comprises the steps of using the U-shaped steel bar clamp to wrap concrete steel pipes by being matched with the clamp, enabling the steel pump pipe in the clamp to be connected with a ground pump delivery pipe, performing concrete jacking construction, embedding the baffle after construction completion, dismounting the leading-in device after baffle reinforcement and the like. The concrete leading-in device has the main advantages that the problem that a concrete leading-in pipe is directly welded with the concrete steel pipe and accordingly the structural performance is destroyed in the prior art is avoided, meanwhile construction materials are saved, all construction tasks can be completed only by preparing two to three clamps, a construction period can be further shortened, construction cost can be reduced, and construction efficiency can be improved.
