ABSTRACT:
System for measuring the penetration depth of an elongated object such as a pile, tube, sheet pile or drill into the ground, to be used in combination with an installation for bringing the elongated object into the ground for instance by pressing, hammering, vibrating, drilling or lowering, or for pulling or otherwise removing the elongated object out of the ground. The system comprises a member for measuring the displacement of the elongated object embodied as a flexible elongated element the weight of which is uniformly distributed along its length, the length being at least equal to the maximum displacement of the elongated object. At least part of the elongated element is supported by a supporting surface. Structure is present to determine the total weight of that section of the flexible elongated element which is supported by the supporting surface.
