The invention relates to a reversal rail hydraulic climbing form for concrete pouring of a high and steep slope. The reversal rail hydraulic climbing form comprises a formwork (25), a traveling device and a rail (21), wherein the formwork (25) is loaded on the traveling device; the rail (21) is I-shaped; a rail support (20) is arranged at the lower part of the rail (21); anchor rods (19) inserted into a bedrock surface (24) are uniformly distributed at the bottom of the rail support (20); clamping holes are uniformly formed in the upper side of the rail (21); the traveling device consists of traveling wheels (1), a main shaft (4), an auxiliary shaft (7), reversal wheels (9), traveling clamping teeth (17), a hydraulic climbing oil cylinder (18) and a traveling bracket. According to the reversal rail hydraulic climbing form, the formwork can be pulled by a hydraulic system to automatically lift on a slope surface, the uplift pressure of concrete can be balanced by reversal wheel pressure, lifting positioning of the hydraulic oil cylinder can be realized by a special rail, the climbing form can be positioned by self-locking of grabbing teeth, and the problems of insufficient uplift pressure and difficulty in ascending movement of the concrete of the high and steep slope are avoided.
