Dynamic penetrometer for geotechnical studies.

摘要

DYNAMIC penetrometer GEOTECHNICAL STUDIES. IS FORMED FROM A SET STAND-TRIGGER MACE (1) provided with a housing in which two compartments (2 and 5) DEFINED IN THE FIRST OF WHICH PLAYS Vertically HAMMER (3) CREATE A GUIDE POSTING OF THE SAME, while the second establishes a chain (6) driven by a hydraulic motor (8) and which is fixed a cam (9) In its upward movement enters the compartment (2) OF THE HAMMER , THROUGH sLOT linking both compartments and impinges on a side shoulder (10) of said MAZA dragging upwards to a position upper limit, wherein said HAMMER IS RELEASED SUDDENLY TO fALL BY GRAVITY HITTING THE ANVIL (4) TRANSMITTING impact through ROD CLASSIC TO CONE PENETRATION. A sensor (11) ON SERVING THE HOOK (9) at each complete rotation of the chain (6) ALLOWS ACCOUNT FOR AND ESTABLISH THE CADENCE OF BEATING THE HAMMER (3), BESIDES BEING THIS JOINT SUPPORT-TRIGGER (1) ESTABLISHED ON positioner allowing free vertical movement of SAME AND WHERE ANOTHER COUPLE OF SENSORS PROVIDED IN TURN INFORMATION, TO A JOINT REGISTRAR, REGARDING THE PROGRESS AND SPEED OF pENETRATION CONE PARALLEL TO THE ROD ASSOCIATES SIDEWAYS a hydraulic cylinder provided with another SENSOR, namely a transducer turn supplies information about SIDE fRICTION CONE pENETRATION, AND FOR ALL INFORMATION PROVIDED THESE SENSORS REGISTRAR DIGITALLY shows the parameters studied.
