DMT-W3 Marchetti Dilatometer (DMT) equipment
Product introduction:
DMT test has the functions and advantages of static cone penetration and side 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 at home and abroad, and it has a DMT data processing system (software) and two-way communication with it.
It can provide many important parameters of soil: lateral pressure coefficient Ko, pore water pressure U, undrained shear strength Cu, effective internal friction angle of sand Φ, bed reaction coefficient Kn, over-consolidation ratio OCR, compression modulus, Elastic modulus, shear modulus, division and naming of soil layers, compaction control, bulk density, judgment of sandy soil liquefaction... etc.
1. Penetration is generally pressed into the soil with a static cone penetrating machine, or into the soil with a dynamic penetrating hammer. 2. DMT test is suitable for all kinds of clay, silt and all kinds of sandy soil layers. 3. Using U disk storage and transmission, data transmission with the computer is more efficient and convenient. Product main parameters: 1. Test probe: length 230-240mm, width 95mm, thickness 15mm; 2. Diameter of steel film: 60mm; 3. Rated air pressure: ; 4. Test depth: 0-50m (special stratum can be deepened); test spacing can be adjusted arbitrarily according to actual needs. 5. Indication error of the whole process: ±0.1%F.S 6. The number of test results storage holes is up to 9999. 7. Low power consumption, using rechargeable lithium battery, standby time up to 24 hours. 8. The measurement and control instrument is displayed as a liquid crystal display 9. Make DMT data processing system (software) and its two-way communication
