1. A grouting pipe, wherein the grouting pipe is configured to construct an isolation layer in a desert area to form a desert water storage area above; wherein
the grouting pipe comprises a bendable pipe body and a plurality of anchoring claws connected around the pipe body and provided with a grouting flow channel;
the pipe body comprises an inner pipe and an outer pipe sleeved on the inner pipe, an annular cavity is formed between the inner pipe and the outer pipe, the pipe body comprises a proximal end and a distal end which are oppositely arranged, and a distal end valve is arranged in a distal end of the inner pipe;
the anchoring claw is mounted in the annular cavity through a rotating shaft, an outer pipe opening is arranged in an area on the outer pipe corresponding to the anchoring claw, and the anchoring claw is capable of swinging outwards through the outer pipe opening;
an elastic bag structure capable of driving the anchoring claw to swing outwards is connected between the anchoring claw and the inner pipe, and the elastic bag structure communicates the inner pipe with the grouting flow channel; wherein
when the elastic bag structure is in a retracted state, the anchoring claw is accommodated in the annular cavity and/or the outer pipe opening under an action of the elastic bag structure; and
when the elastic bag structure is filled with slurry and in an expanded state, the anchoring claw swings outwards through the outer pipe opening, and the anchoring claw swinging outwards is configured to be inserted into surrounding sand grains for grouting into the surrounding sand grains.
