The invention discloses a loading structure for a static load test of a driven pile foundation and a construction method of the loading structure for the static load test of the driven pile foundation. The loading structure for the static load test of the driven pile foundation comprises steel pipe stand columns, a bottom layer stand column connecting system and a cross beam, wherein the four steel pipe stand columns which are connected into a whole are arranged on the top of the cross beam, the bottom layer stand column connecting system is arranged at the position, close to the column bottoms of the stand pipe stand columns, of the bottom of the cross beam, is welded to the intersecting lines of the steel pipe stand columns in a cutting mode, and serves as a communicating pipe, and the cross beam serves as a load distribution platform. The loading structure for the static load test of the driven pile foundation and the construction method of the loading structure for the static load test of the driven pile foundation have the advantages that the problem that according to a single driven pile foundation, due to the fact that the load distribution range is limited, the designed value required by the test cannot be achieved when rolled steel or sand bags are adopted is solved, and the problems that the load stacking height needed by the designed value of the test is large, the danger coefficient is increased, and operation is difficult are solved; in addition, the investment of the structures such as jacks, hydraulic pumps, counterforce beams and anchor piles is reduced; the test cost is low, construction is convenient, operation is easy, loading and unloading can be stably carried out, the quantity and the time of loading can be easily controlled, accuracy of the static load test is improved, and high popularization value is achieved.
