Core drilling drilling rig YSSL-500

explorationwater wellcrawler

YSSL-500 water well drilling rig, which is a full hydraulic crawler water well drilling rig, is mainly used in water well or water exploration hole; but also used in foundation engineering small diameter hole grouting construction. Feature ● Drilling Rig has double power heads, needn’t driving rod; It has the long feeding stroke which is helpful to reduce the rod reversion frequency, avoid core block, and improve productivity. It also can achieve compression or decompression during the full feeding stroke. ● Drilling Rig installed the front and the rear power heads, which makes a variety of drilling methods possible ● When drilling a hole in fractured zone or congeries, drill rod power head connected with DTH hammer and bits, to realize percussion rotary drilling. Meanwhile, casing tube power head rotates the follow-up casing for protecting the hole wall. The two power head can be synchronize to drill hole rapidly. ● When drilling a hole in incoherent overlying formation, quicksand layer and silt layer, the inner drilling tool use conventional rotary tools or long auger drilling tools, meanwhile, the front power head rotates the following-up casing for protecting hole wall. ● When drilling a hole in intact formation, could use power head alone for ordinary rotary drilling or percussion-rotary drilling. ● Floating mechanism in the main spindle of top drive power head protects drill rod screw thread. Casing tube can also used as screw machine to make clamping and loosening drilling tools’ mechanization. ● Drilling Rig’s feeding structure could work with winch together to meet special demand of technical and reduce the strength of labor.
