Hole bottom load test force transmission device

The utility model relates to the technical field of load tests, and discloses a hole bottom load test force transmission device which comprises a base, a jack is fixedly installed on the inner surface of the bottom of the base, springs are fixedly installed on the inner surfaces of four telescopic pipes, and concrete protection arms are movably arranged on the outer surfaces of four supporting blocks in a sleeved mode. According to the hole bottom load test force transmission device, a deep flat plate to be detected is placed on the concrete guard arm, the jack is opened to apply pressure to the top plate, the top plate transmits the force to the four support arms, and the four support arms are symmetrically distributed in an array manner, so that the pressure applied by the jack can be uniformly transmitted to the concrete guard arm; and the concrete protection arm transmits the extrusion force to the deep flat plate to carry out load detection on the deep flat plate, so that the problem of test data deviati
