However, as the pile holes are too deep, no soil sucking machine for sucking soil at the bottoms of the pile holes is available at present, the rotary drilling rig can only be used for drilling, but the rotary drilling rig can take very little soil every time, so that the soil in one pile hole needs to be completely drilled basically, a plurality of pile holes are formed in one construction site, the soil at the bottoms of each pile hole needs to be completely drilled, and the construction progress is seriously influenced by the time of tens of days or even one month. Meanwhile, as the soil in each place is different, the viscosity and humidity of the soil in some places are slightly higher, so that the soil sucked from the bottom of the pile hole is easy to agglomerate in the collecting device or adhere to the inner wall of the collecting device, manual shoveling is needed, in addition, the falling speed of the soil from the collecting device to the trolley is not easy to control, and the soil is too full of the trolley and is scattered; some carts are too small.

The method comprises the steps of (1.1) sucking the slag from an air suction opening at the top of a vortex separating cylinder (5) by using a fan, forming negative pressure in the vortex separating cylinder (5), tangentially sucking the slag at the bottom of a pile hole into an inner cavity of the vortex separating cylinder (5) along the wall of the vortex separating cylinder (5) under the drive of airflow, enabling the slag with larger particle size to directly fall into a slag collecting cylinder (6) under the action of gravity, and enabling the slag with smaller particle size to perform vortex motion along with vortex airflow from bottom to top along the inner cavity of the vortex separating cylinder (5);
And (1.2) in the process of vortex movement from bottom to top, the inner diameter of the conical vortex separating cylinder (5) gradually becomes smaller, slag with smaller particle size is separated from the air flow under the action of centrifugal force along with the air flow rotating at high speed, is thrown into the slag collecting tank (501), and spirally bypasses from top to bottom along the spiral channel of the slag collecting tank (501) under the action of self gravity and tangential impact force, and slides down and enters the slag collecting cylinder (6).
8. The method for sucking and separating the slag soil in the holes of the viscous virtual soil pile according to claim 7, wherein the step (2) is specifically as follows:
(2.1) the muck discharged from the vortex separating cylinder (5) enters the muck collecting cylinder (6) and is discharged from top to bottom along the funnel-shaped inner wall of the muck collecting cylinder (6);
(2.2) the dregs enter the discharge valve (1) from the direction vertical to the rotation center of the discharge valve (1), fall on the rotating blades (102), rotate and disperse along with the rotation of the rotating blades (102) of the discharge valve (1), and are discharged when the rotating blades (102) rotate to the bottom of the discharge valve (1) and pass through the valve body outlet (4), so that the discharge is completed.
