[0019] The following is a further explanation of the technical solution of the utility model in conjunction with the accompanying drawings:

[0020] like Figure 1-Figure 4As shown, a shaping tool for cleaning the core soil of a concrete prefabricated pipe pile comprises a steel pipe 1. Four steel bars 2 are evenly welded on the outer wall of the steel pipe 1. The steel bars 2 can reinforce the strength of the steel pipe 1. A through hole is opened near the end of the steel pipe 1. A ring-shaped steel wire rope 4 is arranged on the through hole. A locking buckle is connected at the end of the steel wire rope 4 to form a closed ring for the steel wire rope 4. A ring cover 3 is arranged at the upper end of the steel pipe 1 on one side of the steel wire rope 4.

[0021] Four steel bars 2 are located on the steel pipe 1 below the ring cover 3. The ring cover 3 is provided with notch grooves corresponding to the through holes, so that the steel wire rope 4 can be easily pulled. A cleaning piece 8 is slidably installed inside the steel pipe 1. The cleaning piece 8 is set on the ring cover 3 through the fixing piece 5. When the cleaning piece 8 is in use, a connecting rod 7 that cooperates with it is provided.

[0022] The cleaning member 8 is configured as a disc-shaped push plate, which is slidably connected to the inner wall of the steel pipe 1 , and a clamping column 6 is fixed at the center position of one side of the push plate.

[0023] The fixing part 5 includes a circular hole 31 opened at the center position of the ring cover 3. The clamping column 6 passes through the circular hole 31 and is threadedly connected to the fixing ring. The outer diameter of the fixing ring is larger than the diameter of the circular hole 31. This arrangement prevents the fixing ring from being stuck in the circular hole 31. When the steel pipe 1 needs to be cleaned of debris, the staff fixes the clamping column 6 fixed on the push plate to the upper end of the steel pipe 1 through the fixing ring to prevent the push plate from slipping out of the steel pipe 1 when the steel pipe 1 is vertically downward, which has a fixed limiting function.

[0024] When the staff is cleaning the debris inside the steel pipe 1 , the staff inserts the connecting rod 7 into the clamping column 6 . A clamping groove is provided at one end of the connecting rod 7 . The clamping groove cooperates with the clamping column 6 , and the connecting rod 7 is slidably connected to the circular hole 31 .

[0025] Working principle: When in use, the staff slides the push plate to the upper end of the steel pipe 1, fixes it with a fixing ring, and then hangs the wire rope 4 on the excavator bucket. The steel pipe 1 is vertical, and the lower end of the steel pipe 1 is inserted into the pile core that needs to be cleaned. The ring cover 3 is pressed by the excavator bucket, and the steel bar 2 and the steel pipe 1 move downward as a whole, and the slag of the prefabricated pipe pile core is pressed into the steel pipe 1. After reaching the cleaning depth, the excavator lifts the steel pipe 1 through the wire rope 4, and the steel pipe 1 is lifted out of the concrete prefabricated pipe pile core. Then the staff removes the fixing ring, inserts the slot at one end of the connecting rod 7 into the card column 6, and then the staff pushes the connecting rod 7 with force. The connecting rod 7 drives the push plate to move, and the push plate discharges the slag from the steel pipe 1. Then the staff inserts the connecting rod 7 into the other end of the steel pipe 1 again, slides the push plate to the other side of the steel pipe 1, and then fixes it with a fixing ring.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
