Soil substance density determining method for e.g. hardening survey in earthwork, involves determining wet and dry density of substance from pit capacity, mass of substance and humidity ratio

摘要

The method involves excavating soil substance (14) of a testing pit (4), and measuring capacity of the pit. Mass and humidity ratio of the excavated substance are measured. Wet and dry density of the substance is determined by scanning a marked terrain surface (6) of the pit by surface scanning as zero level scanning. The pit capacity is determined from measured distances between a scanning head (3) and the terrain surface, depth and terrain surface. The density of the substance is determined from the pit capacity, the mass of the substance and the humidity ratio. An independent claim is also included for a device for determining density of a soil substance of a testing pit.
