传统上是用特制的水泥浆进行加固和隔离孔壁的。通过加压使水泥浆进入钻孔,以便岩层浸透水泥浆,在孔壁上形成泥皮。但如果孔深再增加,就会产生一系列困难:需要大功率的泵和更多的(数百吨)水泥浆。综合地质队的科研人员研究出一 Traditionally, special-purpose grouts have been used to reinforce and isolate the cell wall. The grout is forced into the borehole by pressing so that the rock formation saturates the mud and forms a mud on the walls of the holes. But if the hole depth increases again, there are a number of difficulties that arise: high power pumps and more (hundreds of tons) of grout are required. Integrated geological team of researchers to study a
