[0022] In the embodiment, the rotary drilling rig slurry discharge bucket body comprising a bucket barrel 1 belongs to the existing mature technology, when in use, a rotary drilling bucket with a diameter of 100mm smaller than the designed pile diameter is selected, in order to ensure the hole forming pile diameter, we need to set the digging teeth with a length of 50mm longer than the diameter of the bottom of the bucket barrel 1 at both ends, then we connect the cable to the rotary drilling rig slurry discharge bucket, start drilling into the preset position until the designed pile bottom elevation is reached. During rotation, the operator slowly lifts the bucket at low speed, collects soil, at the same time, the mud is discharged through the two circular upper slurry discharge holes with diameters of 80mm and 100mm symmetrically arranged on the side wall of the bucket barrel 1 and the circular arc drainage hole with a height of 100mm symmetrically arranged at the bottom of the bucket. In this way, during the rotation of the bucket, we can increase the flow rate of the annular mud and control the lifting speed, so as to quickly reduce the negative pressure generated at the bottom of the bucket, effectively prevent the expansion of the hole collapse;
