[0019] In order to make the technical means, creative features, purposes and effects of the utility model more clearly understood, the utility model will be further described below in combination with specific embodiments.

[0020] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme:

[0021] A socket type connecting device for cast-in-place pile blanking pipeline, including upper cast-in-place pile guide pipe 1 and lower cast-in-place pile guide pipe 2, further including ring positioning hoop 3 and guide pipe fixing device 4, the ring positioning hoop 3 is welded in the upper cast-in-place pile guide pipe 1 bundle wall inboard;The guide pipe fixing device 4 is composed of fixed slot 41, hole pin shaft 42 and anti -drop bolt 43, the fixed slot 41 is oppositely arranged on the outer wall of upper cast-in-place pile guide pipe 1 and lower cast-in-place pile guide pipe 2;

[0022] The perforated pin 42 is provided with a reserved hole 421; after the perforated pin 42 is inserted into the fixing slot 41, it is fixed to the perforated pin 42 by passing through the reserved hole 421 through the anti-dropping pin 43.

[0023] The bottom of the annular positioning hoop 3 is provided with a sealing gasket 5;

[0024] The upper grouting pile guide pipe 1 and the lower grouting pile guide pipe 2 are hollow guide pipes;

[0025] The axial extension length of the perforated pin 42 is greater than the distance between the two fixing slots 41;

[0026] The diameter of the lower grouting pile guide pipe 2 is smaller than the diameter of the upper grouting pile guide pipe 1.

[0027] In an feasible manner, the annular positioning hoop 3 is welded to the inner side of the upper grouting pile guide 1, which facilitates a reliable connection between the upper grouting pile guide 1 and the lower grouting pile guide 2. Furthermore, the bottom of the annular positioning hoop 3 is equipped with a sealing gasket 5 to ensure the sealing of the guide duct and prevent concrete flow. The guide duct fixing device 4 consists of a fixing slot 41, a perforated pin 42, and an anti-detachment pin 43. The fixing slot 41 is positioned opposite to each other on the outer walls of the upper grouting pile guide 1 and the lower grouting pile guide 2. The perforated pin 42 passes through the fixing slot 41 and is fixed by the anti-detachment pin 43. The perforated pin 42 has a pre-drilled hole 421, through which the anti-detachment pin 43 passes and is fixed to the perforated pin 42. This double-layer protection improves the reliability and stability of the upper grouting pile guide 1 and the lower grouting pile guide 2.
