APPARATUS FOR PERMEABILITY TO INTERPRET FROM HYDRAULIC PROPERTIES IN FLUVIAL DEPOSITS AND STREAM DEPOSITS

摘要

PURPOSE: A permeability testing device for analyzing hydraulic properties of a river bed and a channel deposit is provided to be easily and conveniently installed on a site and to perform a test. CONSTITUTION: A permeability testing device (100) for analyzing hydraulic properties of a river bed and a channel deposit includes hollow upper and lower casings (144, 150), a drilling bit (156), a cover (110), and an inner automatic water level measuring device (142). The drilling bit is joined to the lower part of the lower casing to be detached and drills the river bed. The cover is installed on the upper part of the upper casing to be detached and includes a water supply hole (116) capable of supplying water inside. The inner automatic water level measuring device is connected to the cover with a rope and automatically measures the level of the inside of the casing.
