【Scope of application】
It is used to test all kinds of geotechnical impermeable materials, such as geomembrane, composite geomembrane, geotechnical waterproof membrane material, and other waterproof and impermeable materials to determine the hydrostatic pressure resistance.
【Test Principle】
When the pressure head on both sides of the sample reaches a certain value, the sample ruptures; increase the hydraulic pressure difference on both sides step by step and keep it for a certain period of time. When the seepage flow increases rapidly, indicating that the sample is damaged, the hydrostatic pressure value is obtained. The machine can contain two functions, namely the measurement of hydrostatic pressure resistance and the measurement of permeability coefficient.
【Standards compliant】
"Determination of Permeability of Composite Geomembrane" GB/T17642-1998
"GB/T 17642-2008 Geosynthetics Nonwovens Composite Geomembrane"
GB/T19979 "Impermeability of Geosynthetics"
JTG E50-2006
【Instrument characteristics】
1. High-definition touch color screen operation, digital display, automatic calculation of the program, and printable results.
2. The test fixture is made of high-quality stainless steel, corrosion-resistant, easy to clean, and beautiful.
3. One machine is multi-purpose, that is, the hydrostatic pressure test and the permeability coefficient test are satisfied at the same time.
4. The surface treatment of the body: adopts DuPont powder from the United States, electrostatic spray paint process, curing at a high temperature of 200 ℃ to ensure that the color will not fade for a long time.
5. Use transparent plexiglass test chamber to prevent water splash and dust from entering.
