Abstract
The invention discloses a novel Guelph permeameter for measuring soil permeability. The novel Guelph permeameter is characterized by comprising two parts, namely a pressure regulation chamber (1) and a water supply chamber. The novel Guelph permeameter disclosed by the invention achieves the easier implementation of field measurement by overcoming the defect of limitation that the water supply chamber is originally required to be placed in a well, ensures that a measured value is more accurate and representative by reducing the destroy and influence on soil by determining the position of the permanent water level inside a drill hole through the regulation of the pressure regulation chamber (1) and an air inlet pipe and is greatly enlarged in use range by more relaxing the specification requirements of the drill hole.
