Apparatus for in-situ measuring rock, geological and building material permeability by making use of weight loss of pulled measuring medium by means of sensitive weighing device

摘要

Equipment for field measurement of permeability of rocks, geotechnical and construction material is based on the principle of weight loss Depressed measuring media when water pressure tests (RPM) using sensitive scales. This principle is reached by 2-4 orders of magnitude greater sensitivity measurement of consumption at the RPM compared to previously used techniques is therefore possible to realize in-situ tests in matrices with very low permeability used as sealing elements of buildings. The invention also includes methods of measurement.
