Some Characteristics Of Soil Stabilization By 'sealed' Injection Using Microcement

摘要

1. Successful stabilization of various deliquescent soils existing under an appreciable excess pressure is possible only with a sufficiently high technological level of work production: the existence of appropriate equipment, highly qualified personnel, continuous recording of parameters, and constant adjustment of the procedure during the execution of work.rn2. To reduce losses of suspension extruded beyond the limits of the zone being stabilized, the suspension should be restrained by barrier rows of holes. Around the outer boundary of the zone, it is expedient to conduct "jet" injection, and injection of bentonite-cement and finely disperse grouts.rn3. For a soil with a certain particle size, a specific type of microcement, and the consistency of the injection suspension should be selected with consideration given to the actual degree of compaction of the soil. The boundaries of suspension penetration into the soil can be determined from its permeability at the job site. It should be considered that use of different laboratory procedures will result in significant discrepancies in the results.
