我们在使用泥浆钻进过程中,试制了一种新的冲孔工具,即鬃刷一喷水枪冲孔器,它能使泥浆钻孔孔壁上的“泥皮”很快被冲洗掉,使原来泥浆钻孔要用10余天才能稳定的地下水位缩短到几个小时,达到了效率高质量好。简介于后。一、构造 During the mud drilling process, we developed a new punching tool, namely a bristle brush-jet puncher, which allowed the “mud” on the wall of the mud hole to be quickly washed Off, so that the original mud drilling to use more than 10 days to stabilize the groundwater level shortened to a few hours, to achieve high efficiency and good quality. Brief introduction in the later. First, the structure
