[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0017] As shown in the figure, the utility model describes a convenient prefabricated short pile drilling device for revetment, comprising a water pump 4, a water pipe 3, a short steel pipe 2 and a long steel pipe 1, wherein the water pump 4 is connected to one end of the water pipe 3, and the other end of the water pipe 3 is connected to the short steel pipe 2, and the long steel pipe 1 is fixed on the outer side of the short steel pipe 2, and the short steel pipe 2 is arranged parallel to the long steel pipe 1.

[0018] The manufacturing process of the device is: weld a 3m long Φ30*2.8 long steel pipe 1 with a 5cm long Φ80*3.5 short steel pipe 2 (leave a 2cm length at the rear end of the short steel pipe 2 slightly smaller in diameter for connecting the water pipe), then connect the short steel pipe 2 and the water pipe 3 with wire binding, and the other end of the water pipe 3 is connected to the water pump 4 equipment.

[0019] When in use, the water pump 4 is installed in place, the water inlet pipe is placed at a nearby water source, such as a river, and the water outlet pipe is placed at the designed pile position of the prefabricated short pile. The operator holds the long steel pipe 1 vertically, aligns it with the pile position, starts the water pump, and uses the method of water flow impact to guide the hole, penetrate the sand and silt layers and other soil layers where the prefabricated short piles are difficult to sink, and then static pressure prefabricated short pile construction is carried out.

[0020] After the operation is completed, the device can be dismantled and recycled.
