Title:
FAST SAND FIXING METHOD FOR HIGH-TEMPERATURE AND HIGH-SALT DESERT BASED ON SANDSTONE COVERING
Document Type and Number:
WIPO Patent Application WO/2021/036399
Kind Code:
A1
Abstract:
Disclosed is a fast sand fixing method for a high-temperature and high-salt desert based on sandstone covering. The fast sand fixing method comprises the following steps: step 1, performing geological exploration on a desert area to be controlled, and determining a sandstone excavation area; step 2, clearing floating sand on the surface layer of the sandstone excavation area, and excavating bottom sandstone; step 3, stirring the excavated sandstone by sprinkling salt water; step 4, evenly covering the desert surface layer with the stirred sandstone to form a sandstone covering layer; step 5, compacting the sandstone covering layer; and step 6, providing a water infiltration groove on the compacted sandstone covering layer to control a high-temperature desert area. The fast sand fixing method for the desert in the present invention is simple in operation, short in sand-fixation cycle, and low in cost, the limitations of poor high-temperature resistance, low wind resistance and weak water resistance of the conventional desert control can be overcome, and the desert control efficiency is improved.
