●The DMT test combines the functions and advantages of a static penetration test and a pressure test: the test is fast, accurate and economical.
●The test data has good reproducibility, small human influence factors, automatic data acquisition and storage, and automatic control of test signals. It is the first of its kind at home and abroad, and has a DMT data processing system (software) and two-way communication.
●Can provide many important parameters of soil: side pressure coefficient Ko, pore water pressure U, undrained shear strength Cu, sand effective internal friction angle Φ, bed reaction coefficient Kn, over consolidation ratio OCR, compression modulus, Elastic modulus, shear modulus, division of soil layers and naming, compaction control, bulk density, determination of sand liquefaction, etc.
●Test pressure range 0～6MPa Test depth: 0～50m (soft soil can be deepened)
●The penetration is generally pressed into the soil by a static probe, or it can be hammered into the soil.
●The DMT test applies to all types of clay, silt and various types of sand soil.
