- 摘要：
The ground has introduced or injected into it a solvent fluid mixt. of water glass and an acid reagent. The pH value of the mixt. is in a range between weakly acid and weakly alkaline values. Pref. the fluid contains >=1 of a gelling control agent and clay. The mixt. is chosen so that the above pH level is maintained. Pref. two fluids are used which are combined, the above pH level being maintained, and are injected at high pressure as a jet. Ground water- and soil pollution is minimal.
