Main Features
1, Double driving head equipped with double wall casing, drill pipe, large diameter DTH Drill combination.
2, The mud reverse circulation drilling, air reverse circulation drilling.
3, The high-pressure mud is circulating, air reverse circulation, mud reverse circulation synchronous drilling.
4. The soil layer, pebble bed, weathered rock, rock stratum need not change bit, only changing the process method can complete the complex stratum construction.
5, The drilling efficiency is not affected by drilling depth, groundwater.
6, A 20 cubic meters, 20 kg air compressor under the high pressure air can complete the diameter of 800mm, the depth of 400 meters within the well construction.
7, A 30 cubic, 24 kg high air pressure air compressor can complete diameter 2500mm - 800mm, depth 150 m rock hole construction.
