Title: PENETRATION TESTING APPARATUS
Abstract:
A penetration testing apparatus for testing the bearing strength of ground, soil layers, base- courses, subbases and subgrades without the need for much manual operation, includes the following components operatively connected together, comprising a frame support (5) which supports an actuating apparatus (7), power supply apparatus (9), movable carriage assembly (13), ground penetrating member (15), carriage drive mechanism 17 and ground stabilizing means ( 18), operatively connected together to carry out a ground test. The movable carriage assembly (13) movably supports one ground penetrating member (15). The movable carriage assembly (13) is movably supported by the frame support (5) such that power from the actuating apparatus (7) slidably and mechanically moves the carriage assembly (13) up and down with the ground penetrating member (15), on a portion of the frame support (5), to cause the ground penetrating member (15) to contact or penetrate the ground when the carriage assembly (13) moves down and be slidably moved back up the portion of the frame support (5) to repeat the sliding down movement again.
