To achieve rapid drilling and ensure the quality of borehole formation, it is necessary to rely on impact drilling for formations prone to collapse, such as sand and gravel, crushed stones, rock soil, and sand layers. Especially when the water content in the formation is too high to work with a down-hole impactor, the construction process used by this machine becomes the best choice;Construction application: advanced drilling, horizontal coring, tunnel pipe shed and other tunnel construction; Construction of various engineering projects such as foundation pit support, pilot holes, and micro piles.DetailsSuccessful projects Company Profile Advantages
