When drilling, deionized water is injected into the drill bit through the hollow channel of the drill rod. When the pilot bit drills 26.3m and reaches a first sampling position, namely 9m of underground water, the drill rod reversely rotates and retreats for a distance of about 50cm, the water pumping device is started, and mud in the drill hole is pumped out by the drill rod. And then the drill rod is withdrawn to completely remove the drill rod. And (3) unloading the guide drill bit on the last drill rod, replacing the guide drill bit with a soil sampler, pushing the soil sampler into a sampling position, operating the drilling machine to push the sampler into a soil layer by about 1m, enabling the soil to enter the sampling pipe, withdrawing the drill rods, unloading the drill rods to the last drill rod one by one, unloading the sampling pipe, shearing the sampling pipe to be 30cm long, sealing two ends of the sampling pipe by sealing covers, numbering the sampling pipe, and putting the sampling pipe into a sample storage box to finish soil sampling.
Sampling a second point position, observing the orientation of the guide drill bit through a monitor, enabling the drill bit guide plate to face in a twelve o' clock direction, stopping rotating, pushing the drill rod, and enabling the drill rod to move upwards until the included angle between the drill rod and the horizontal line is adjusted to be 3.8 degrees; stopping propelling, rotating the drill rod to drill for 15.03m to reach a second sampling point, and sampling soil and underground water according to the same method. When the second sampling point is completed, the direction of the guide plate is adjusted to be about 0.54 degrees upwards, and the third sampling point is reached by screwing 35.06m, and the method is adopted.
And after sampling is finished, pushing the drill rod into the drill hole, injecting bentonite or cement slurry into the hollow drill rod, and gradually injecting the bentonite or cement slurry until the ground to finish plugging when the drill rod is pulled out one by one.
