掏泥桶又名管钻,是钢绳冲击钻探中的一种工具.其下面装有阀门,上面连接钢丝绳?钻探时,将钢丝绳一拉一放,冲到泥水混合的钻孔中后,泥浆即冲开阀门进入管内,借以取出样品、进行观测样品.由于掏泥桶上面钢绳有弹力(一般所用的钢绳多为?4/8时～?5/8时)且泥浆浓、密度大,浮力也就大,故每当掏泥桶在孔中冲入泥浆时,冲力就大大减少,甚致很轻, Drilling mud, also known as pipe drilling, is a tool used in impact drilling of steel wire rope, which is equipped with a valve underneath for connecting steel wire ropes. When drilling, the steel wire rope is pulled and released into the muddy water mixing hole. That is, open the valve into the tube, in order to remove the sample for observation samples.Because the dig rope above the elastic rope (generally used when the rope is more than 4/8 ~ 5/8) and thick mud, high density , Buoyancy is also large, so whenever the dig mud in the hole into the mud, the impact will be greatly reduced, even very light,
