reverse circulation water well/geotechnical investigation/soil testing drill rig  

reverse circulation water well/geotechnical investigation/soil testing drill rig

The reverse circulation drilling rig has a shock frequency of 40 times/min, the main and auxiliary hoisting lifting capacity is 30KN, the motor power is 45KW, and the reverse circulation 6BS pump is not included. The weight of the impact drill is 4T. The drill bit is cast as a whole, with high impact resistance, large impact, high drilling efficiency, and suitable for reverse circulation impact diameter of 800~1500mm. The reverse circulation main and auxiliary winch lifting capacity is 50Kn, the drilling diameter is 2.0m, the drilling depth is 80m, the winding stroke is 1.5~3.0m, the main engine power is 75KW, and the reverse circulation pump set is 3PNL and 6BS pump can be equipped with hydraulic step and vertical displacement. In addition to the impact tip, the drill bit is made of a steel plate of 50mm or more, and can also be equipped with a variety of drill bits. This series of reverse circulation drilling rigs is suitable for complex foundation engineering such as soil layer, pebbles and soft rock. It is widely used in bridge bored piles and underground continuous wall foundation engineering.
