Flat Dilatometer Testing Machine

The test method of DMT-D flat shovel lateral expansion test machine is fast, accurate and economical, and it is quickly promoted and applied all over the world. The DMT-D instrument is developed with reference to the main technical indicators of the Italian DMT instrument. After a large number of test comparisons of the two instruments in the room and on the spot, the measured results are consistent, indicating that the test results of the DMT-D instrument can be quoted from the internationally mature DMT. The formula calculates the geotechnical parameters of various types of soil. Moreover, the DMT-D instrument has a simple structure, is durable and easy to operate and maintain. Adding a pressure sensing element for testing and monitoring expands the DMT test function, making the measured results more accurate and reliable.

Product performance:

●DMT test has the functions and advantages of static penetration test and lateral pressure test: the test is fast, accurate and economical.

●The reproducibility of the test data is good, the human factors are small, the data is collected and stored automatically, and the test signal is automatically controlled.

Can provide many important parameters of soil: lateral pressure coefficient Ko, pore water pressure U, undrained shear strength Cu, effective internal friction angle Φ of sandy soil, 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.

●Test pressure range 0～6MPa Test depth: 0～50m (soft soil can be deepened)

●Penetration is usually pressed into the soil with a static penetrating machine, and can also be hammered into the soil with a dynamic hammer.

●DMT test is suitable for all kinds of clay, silt and all kinds of sandy soil layers.
