Abstract: Disclosed are a grouting pipe and a construction method of a desert water storage area. An isolation layer can be constructed in any desert area to form the water storage area. A plurality of anchoring claws are arranged between an inner pipe and an outer pipe of a pipe body. The anchoring claw has a grouting flow channel for grouting into surrounding sand grains. When the grouting pipe is being laid, the anchoring claw is folded. During grouting, an elastic bag structure supports the anchoring claw. The pipe body can be firmly anchored in the sand grains. Slurry sprayed out of the anchoring claw moves from the pipe body by a certain distance, with a wider flowing range in the sand grains, and can meet and condense with slurries of other drilled holes, which facilitates better formation of the isolation layer, so that the desert water storage area is formed.
