Dynamic pyrotechnical penetrometer.

THE PYROTECHNICAL DYNAMIC PENETROMENTER ALLOWS TO DETERMINE THE CHARACTERISTICS OF THE SOILS BY FLOODING, DETECTED AND MEASURED IN CONTINUATION OF A PROBE ROD (1) BY PRESSURE CREATED BY A PIROTECHNICAL GAS GENERATOR (5). IN AN AMAGNETIC TUBE EQUIPPED WITH SOLENOIDS, IT IS PLACED BY A STOP, A PROBE BAR (1) PATTERN SET ON A PISTON (2) IN WHICH A MAGNET 83 IS STAYED AND ON THE OTHER PART, A RECULING MASS (4) THAT BALANCES THE QUANTITY OF MOVEMENT OF THE ROD CREATED BY THE GASES OF A PYROTECHNICAL GENERATOR (5) CONTAINED IN THIS RECULING MASS. A BOX OF ACQUISITION AND MOVEMENT TREATMENT OF THE VARILLA PATRON ALLOWS TO CALCULATE THE RESISTANCE OF THE SOIL TO THE SUNK OF THE VARILLA.
