煤田一分队勘探地区,孔内漏水很严重,经过多次采用不同堵漏方法——采用锯木、棉丝(破烂棉被)、洋灰、泥浆混合液、堵塞漏水,得到良好效果。操作方法:(1)泥浆混合此例:1立方米泥浆内加100～150市斤锯木,2～3市斤棉丝,100～150市斤洋灰。总之,应根据漏隙的实际情况适当的配合,但混合液要能够流动。(2)将上述混合液灌满孔内,然后用螺丝头上在套管上,开动水泵进行下压(压力表指针应在15～20
Coalfield first exploration area, the hole leakage is very serious, after repeated use of different methods of plugging - using sawnwood, cotton (tattered quilts), cement, mud mixture, plug the water leakage, get good results. Operation method: (1) Mixing slurry In this example, 1 cubic meter of mud is added with 100 to 150 kilos of sawn timber, 2 to 3 kilos of cotton yarn and 100 to 150 kilos of cement. In short, should be based on the actual situation of leakage appropriate mix, but the mixture should be able to flow. (2) The above mixture was filled hole, and then screw the head on the casing, start the pump down (pressure gauge pointer should be 15 to 20
