[0069] Embodiment 3

[0070] The embodiment of the present application is described in detail with a specific example.

[0071] Select the post-grouting technology of bored cast-in-place piles according to the engineering geological conditions.

[0072] 1) After drilling, make the steel cage and lay out the grouting pipeline equipment and lower it into the borehole. Clean the hole and pour concrete, then unplug and perform acoustic testing.

[0073] 2) The installation preparation of cement slurry making and storage equipment and grouting equipment is completed, and the system platform is turned on.

[0074] 3) Under the control of the system platform, the cement slurry making and storage equipment starts to make and store cement slurry according to the set water-cement ratio (0.6). When the cement slurry making and storage equipment detects that the cement slurry water-cement ratio is 0.6, it starts to provide cement slurry to the rear grouting equipment to grout the pile end and pile side.

[0075] 4) The grouting pipeline equipment transmits the parameters such as grouting flow rate and grouting velocity to the system platform.
