Koken Boring RPD-40C. Mesin pemboran. Crawler mounted

RPD-40C Rotary Percussion Drill Crawler Mounted KOKEN Rotary Percussion Drill RPD Series is equipped with a hydraulic-driven percussion unit developed by our original technics, and is capable of very rapid drilling. RPD-40C Primary Use : Anchoring Water drain drilling Water well drilling Grout hole drilling   The RPD-40C has been newly developed to represent our compact-sized model of arrow drills which has high efficiency of drilling in its small body. This rig will surely play a great role in urban areas where it’s hard for large-sized machines to operate. (melanjutkan) GROUTING Constructions Grouting work for the dam rock bed cracks is conducted for the purpose of preventing spring water and water leak, as well as the integration, strengthening, reinforcement of the rock bed, as opposed to the secondary causes such as the cracks caused by the fault, joints, beddings and some secondary cracks caused by blasting. Grouting materials are commonly cement paste or cement bentonite paste. Grouting methods ●Curtain grouting: retaining permeated flow in the foundation rock bed, reducing uplift presure, preventing water leak. ●Consolidation grouting: Integrating the foundation rock bed, improving deformity. ●Contact grouting: Close connecting concrete dam major structure and its foundation rock bed. ●Blanket grouting: Restraining permeating flow in the surface layer portion of the dam water shutting zone. ●Joint grout: Integration of block joints for concrete dam. Geological Conditions: Sand stone, Mud stone, Tuff breccia, Slate, Schist, Andesite, Granite etc. WATER WELL Drilling A drilling well is a facility in which a hole is dug to collect the ground water by drilling the ground. If dug to the water conduit, the abundant ground water can be utilized half-permanently. Dig a hole in the well ground with a boring machine and insert casing pipes into the ground. Depth ranging shallow 10m to deep 100m.
