METHOD OF CONTINUOUS QUALITY CONTROL OF SOIL COMPACTION AND DEVICE FOR CONTINUOUS QUALITY CONTROL OF SOIL COMPACTION Russian patent published in 1997 - IPC

FIELD: continuous quality control of compaction of soil materials in the process of their compaction by road rollers at construction of causeways. SUBSTANCE: according to measured angular speeds of the roller profiling and compacting parts, their values for fixed time interval or the section of the covered path are calculated, the difference of the obtained angular speeds is calculated, and the ratio between obtained difference and calculated angular speed of one of parts is used as the parameter characterizing the compaction process. The device for continuous quality control of soil compaction uses two tachometers, one of them is installed on the compacting part, and the other, on profiling one, measurand determination unit made in the form of two averaging elements, subtraction unit and ratio calculation unit, and a recording unit. Recording unit may be made in the form of two storage units, comparison element, selector switch, indicator and an audio-signal generator. The profiling part may be made in the form of a traction part of the road roller. EFFECT: enhanced efficiency. 3 cl, 4 dwg
