The present invention relates to a method and a device for the automatic pile-driving of an elongated element into the ground. The device of the present invention includes a pile-driving plant (1) with the free fall of a monkey (7) to drive a pile (2) into the ground, including a load pick-up for measuring the load applied by the monkey hanging cable (8) on a pulley (6), and a winch angular movement pick-up (15). These several pick-ups are connected to an electronic analysis device (13) of the signals generated by said pick-ups so as to automatically control the unclutching, pre-clutching or clutching of the winch (9) by automatic detection of the impact moment of the monkey (7) on the pile (2), of the monkey lifting height and of stop or immobilization moment of the monkey on the pile, respectively. The invention is used in civil engineering. <IMAGE> |
