Rotary Drilling Rig
Featuresof Rotary Drilling Rig
This rotary drilling rig has the flexibility of size (300mm to 2500mm diameter), depth, and speed of installationunder ideal conditions of non-collapsing dry soils. The installation procedurecauses no undue noise and is effectively vibrationless.In view of the size of plant used, clear headroom and an open site results inbetter production than in congested areas.
Obstructions
If any handwork is required to remove for the pile,the shaft diameter should not be less than 900mm.If the sides of the hole collapse or are liableto collapse, or if excessive water is entering above the base of the pile,temporary retractable casing is installed. If ground water cannot be controlledby pumping and / or temporary casing to allow concreting in the dry, thenconcrete is placed under water using a tremie pipe.
DrillingTools: Rock auger, Rock bucket, Soil auger,Soil bucket, Core barrel, Belling auger
