Static pressure construction technology for guide hole in touch-sounding pipe

The invention relates to a static pressure construction technology for a guide hole in a touch-sounding pipe, and belongs to the technical field of a pile driving construction technology for engineering. The static pressure construction technology for the guide hole in the touch-sounding pipe are used for PHC pipe pile static pressure pine sinking, and comprises the following steps that (1), in the process of the PHC pipe pile downward static pressure pile sinking, a drill rod is firstly placed into the cavity of the inner wall of the PHC pipe pile; (2), start static pressure sinking the PHC pipe pile; (3), when the maximum pressure of the static pile press machine cannot make the PHC pipe pile sink, a power device of a hole guiding pile machine is turned on to drive the drill rod to conduct hole guiding on foundation; (4), when the guide hole depth reaches 0.5m-7.0m, the drill rod is lifted up 0.5m-6.0m, and then the PHC pipe pile is sunk by static pressure; and (5), the step three and the step four are carr
