The invention relates to a desert steep slope concrete wet spraying construction process, and belongs to the technical field of slope protection. The method comprises the following steps that S1, the free face and the slope top face of the desert steep slope are coated with cement paste; s2, after the cement paste is condensed, steel bar meshes are laid according to the shapes and sizes of the free face and the slope top face; the reinforcing meshes are separated from the free face and the slope top face through concrete cushion blocks; s3, concrete is sprayed in a segmented, segmented, blocked and layered mode along the reinforcing mesh from bottom to top through a concrete wet spraying machine, and after condensation, a concrete supporting layer is formed; and S4, after the concrete supporting layer is coagulated for 2 h, maintenance and acceptance are sequentially conducted. The problem that in the prior art, no desert steep slope protection measure aiming at the particularity of the hydrogeological condit
