Single-pile vertical compression resistance static load test device

The utility model relates to a single-pile vertical compression resistance static load test device, relates to the technical field of single-pile detection, and aims to improve the stability of the device at a high test tonnage. The test pile is used for being embedded in the ground, the jack abuts against the bottom end of the test pile, the top end of the jack further abuts against a main beam, the bottom wall of the base layer bottom plate can be attached to the ground, the jack penetrates through the base layer bottom plate, and the bottom wall of the supporting frame abuts against the top end of the main beam. The periphery of the supporting frame abuts against the ground, and the distance between the supporting frame and the base layer bottom plate is adjusted through an adjusting mechanism. And by arranging the adjusting mechanism and the base layer bottom plate, the base layer bottom plate can move to the ground, so that a weight for stacking and loading can be placed on the top wall of the base layer
