由保定地区水利局、地矿部技术方法研究队、完县水利局等共同研制的增压机——潜孔锤打基岩井的工艺,已于1985年9月26日由水利电力部、地质矿产部、河北省科委三家鉴定通过.这项新工艺比常规法具有以下优点:一是不用水可以打成井;二是进尺快,一眼150~180米深的基岩井,纯钻进时间是18~20多小时;三是不出假干孔.假干孔的出现是采用常规钻法,在钻进当中钢沙或钢粒、岩粉将井孔的裂隙缝拟堵了,地下水流不到井内,有的井孔根本不出水.
By Baoding District Water Conservancy Bureau, the Ministry of Geology and Mineral Resources Technology Research Team, Duan County Water Conservancy and other jointly developed turbocharger - DTH hammer rock well technology, was September 26, 1985 by the Ministry of Water Conservancy and Electricity, Geology Ministry of Mines, Hebei Provincial Science and Technology Commission identified three passed.This new technology than the conventional method has the following advantages: First, no water can be made into a well; Second, into the fast, a 150-180 meters deep rock shaft, pure drilling time Is 18 to more than 20 hours; three is not fake dry hole .Fake dry hole appears is the use of conventional drilling method, among the steel or steel particles in the drilling, rock fissure will crack the hole, groundwater flow Not well, some wells did not water.
