เครื่องทดสอบหาการไหลซึมผ่านน้ำของแผ่นใยสังเคราะห์ (Geotextile)

• Geotextile water permeability tester is designed and manufactured according to the requirements of the latest national standard GB/T15789-2005 and water resources SL235 standard. It is suitable for all kinds of geotextiles and composite fabrics with water permeability to test the vertical permeability under constant water head. The machine adopts microcomputer program control, sensor acquisition and measurement. Head difference digital setting, automatic positioning, automatic conversion of permeability coefficient, display, storage, statistics, editing, printing, etc.

Standards : GB/T15789-2005, SL/T235-2012 ASTM D4491-2017 method A- constant head test

Principle

•  Flow velocity of water flowing perpendicular to the plane of the geotextile under a unit hydraulic gradient (mm/s)
