Model: DMT-E3
Description
The flat dilatometer test DMT provides a quick, precise, economical way to test the soil mechanical characteristics in site, the test result features very good consistency with other in situ testings. The DMT was founded by the geotechnical professor Marchetti from Aguila collegue of Italy, it has been used all around the world and already included in the ASTM and Eurocode standards.
Features
Fast & accurate in test, economical in cost
Good test data reproducibility, little man made influence factor, automatic data acquisition, storage, test signal automatic control, unique both way communication available
Multi parameters testable: lateral pressure factor Ko, pore water pressure U, undrained shear strength Cu, sand effective internal friction angle Φ, foundation bed refraction force factor Kn, overconsolidation ration OCR, compression modulus, elastics modulus, shear modulus, soil layer divide and naming, compaction control, unit weight, sandy soil liquidation, etc.
Can use static cone penetration machine or dynamic penetration hammer to press into the soil
Suitable for various kinds of clay soil, silty soil, sandy soil
