Rotary drilling rig may have some sediment at the bottom of the hole during the hole forming process. This is inevitable and can be said to be a defect of rotary drilling rig. Then why does it have sediment at the bottom of the hole? The main reason is that its construction technology is different. The rotary drilling rig method uses non-circulating mud drilling, so the drilling slag cannot be carried to the ground through the circulation of mud to settle down. Our small rotary drilling rig manufacturers can form a rotary drilling rig for continuous slag discharge. There are several main factors for sediment occurrence. Residue between the bucket teeth of the rotary excavator and the bottom cover of the drilling bucket; The bucket teeth of the small rotary drilling rig are sparsely placed, and the drilling slag flowing between the teeth is not

The residue between the bucket teeth of the rotary excavator and the bottom cover of the drilling bucket; The bucket teeth of the small rotary drilling rig are sparsely placed, and drilling slag flowing between the teeth is inevitable; The bottom cover of the drilling tool is not tightly closed; The soil cut by the edge of the outer edge of the drilling bucket of the rotary drilling rig remains at the edge of the bottom of the hole because the bottom of the hole is a plane that cannot enter the inlet of the cylinder. When drilling into mud and plastic stratum, the drilling slag in the drilling bucket is severely lost in the process of raising, and sometimes even completely lost in the drilling hole. The return footage of the drilling bucket is too large, the loading is too full, and the slag is squeezed out from the drainage hole of the roof. National standard rules, conflict type pile, end-bearing pile hole bottom sediment thickness target is not more than 100mm, not more than 50mm.

The above is the factor of small rotary drilling rig forming hole and slag, which is summarized by our pile driver. Although this is an inevitable defect of small rotary drilling rig, the rotary drilling rig is still the most suitable machine for forming hole and piling at this stage. After the hole forming of rotary drilling rig is completed, the hole cleaning operation shall be carried out, so that the sediment at the bottom of the hole can be eliminated.
