APPARATUS FOR MEASURING PERMEABILITY OF SOIL

摘要

PURPOSE: A field permeability measuring system is provided to minimize the measurement error caused by a leakage of water between a casing and the ground at filed permeability test, and to cut off the inflow of collapsed soils into a space within a test section due to the breaking of the ground. CONSTITUTION: A field permeability measuring system(10) comprises: a first casing(11) installed in a test section; a protection net(12) discharging reagent water filled in the first casing into the soil within the test section and preventing the inflow of collapsed soils into the first casing due to the breaking of soils; and a water leakage prevention unit(13) coupled to the outside of the protection net and the first casing and cutting off a leakage of water from the inside of the first casing.
