QUALITY CONTROL METHOD FOR SEALING soil mixture

摘要

A method for controlling the quality of compaction soil mixture comprising sample selection soil mixture, the volume determination, the masses of the sample, the density of the particles of the coarse fraction and fine fraction content of the sample, performing quality control of the seal density fine fraction of the soil, density determination ground mixture to the formula: ρ- density of dry soil soil mixture, g / cc; ρ- coarse fraction the particle density in g / cm; ρ- density dry fine fraction of the soil sample, g / cc; P- silt content, proportion of units, characterized in that the selected sample soil mixture of mini-wells of a small volume, 50-100 times less standard volume measured backfilling excavated sand or water calibration and determine the density of the dry soil sample fine fraction further into several mini-wells, for example five, sampled large mass without measuring its volume and determine the particle size distribution and content of fines therein and with the values ​​obtained is calculated final density of the soil mixture full particle size distribution.
