[0012] The utility model is described in detail below with reference to the accompanying drawings:

[0013] A micro steel pipe pile driving positioning and guiding device comprises a pile base surface 1 and a micro steel pipe pile 9, wherein a steel pipe pile driving mark circle 2 is arranged on the pile base surface 1, marking the driving position of the micro steel pipe pile, a horizontal circular ring support 3 is arranged above the steel pipe pile driving mark circle 2, an outwardly inclined support leg 4 is arranged on the horizontal circular ring support 3, and three outwardly inclined support legs 4 are arranged at equal intervals of 120 degrees at the lower end of the horizontal circular ring support 3, and the outwardly inclined support legs 4 are inserted into the pile base surface 1 outside the steel pipe pile driving mark circle 2 to ensure the stability of the horizontal circular ring support 3 and effectively resist the impact The pile vibrates, and radial telescopic rods 5 are horizontally arranged at equal intervals in the inner circle of the horizontal circular support 3. An arc-shaped clamping plate 6 is fixedly connected to the inner end of the radial telescopic rod 5. The height of the arc-shaped clamping plate 6 is 50 cm. The arc-shaped clamping plates are spliced ​​into a guide sleeve with gaps arranged in the vertical direction. The micro steel pipe pile 9 is arranged in the guide sleeve spliced ​​by the arc-shaped clamping plates. The micro steel pipe pile 9 is arranged directly above the steel pipe pile driving mark circle 2.
