In the present invention, an upper plate and a lower plate are arranged to be spaced apart from the lower side of a concrete pile for reinforcing the strength of the ground, and a pressurizing mechanism applied with a hydraulic jack is installed between the bottom of the upper plate and the upper surface of the lower plate, and hydraulic pressure is applied to the upper plate. It relates to a two-way loading test apparatus for a concrete pile that can contribute to construction safety by testing the static load bearing capacity of a concrete pile by measuring the displacement of the upper and lower plates. (111) is formed to penetrate the upper plate 110, the lower plate 120 installed at a certain distance apart from the lower side of the upper plate 110, and is installed between the upper plate 110 and the lower plate 120, the upper plate ( 110) and the lower plate 120 as a pressing mechanism that applies a vertical load and is disposed under the hydraulic transmission module 130 and the hydraulic transmission module 130 to supply the working fluid with a uniform flow rate and pressure from the hydraulic transmission module 130 It may include a plurality of receiving hydraulic jacks 140, and displacement measuring means for measuring the displacement of the upper plate 110 and the lower plate 120.
