The invention discloses a hydraulic jackdrill reliable test-bed. A horizontal slide guide rail is mounted on test benches, a slide plate is fit on the slide guide rail, a thrust cylinder and a hydraulic spring cylinder are fixed on the test benches at two ends on the motion direction of the slide plate, the thrust cylinder and the hydraulic spring cylinder are arranged opposite, the piston rod of the thrust cylinder is connected with the slide plate, the hydraulic jackdrill to be tested is mounted on the slide plate, and the drill shank of the hydraulic jackdrill to be tested is opposite to the piston of the hydraulic spring cylinder. Or the spool of a reversing valve is removed or a fixed breasting hydraulic jackdrill is adopted to replace the hydraulic spring cylinder, the side water inlet device ports of the hydraulic jackdrill to be tested and the breasting hydraulic jackdrill are communicated via an inner pore canal, and a high pressure air pump is communicated with the side water inlet device port of th
