Active refrigeration and self-recovery cold region side slope support structure and construction method

Abstract

The invention discloses an active refrigeration and self-recovery cold region side slope support structure and a construction method, and belongs to the field of cold region side slope support. The structure comprises a frame, heat anchor pipes and a refrigeration device, wherein the heat anchor pipes are formed by connecting heat pipes with hollow anchor pipes through threads; the refrigeration device is formed by connecting refrigeration sheets, temperature control switches and solar panels through wires; condensation sections of the heat anchor pipes are provided with the refrigeration sheets; an anchorage device, a spring and a backing plate are arranged on each heat anchor pipe in a sleeving manner in sequence, and the heat anchor pipes is arranged in slope holes; slurry is injected into the heat anchor pipes through pressure to anchor the heat anchor pipes in a stable frozen soil layer; a geogrid and the frame are constructed on a slope; the heat anchor pipes are anchored in the frame by using the anchorage devices; a drainage ditch is formed in the toe of the slope; the refrigeration sheets, and the temperature control switches and the solar panels on the frame are connected in sequence by using the wires.

Description

technical field [0001] The invention belongs to the technical field of slope support in cold regions, and in particular relates to an active cooling and self-restoring slope support structure and construction method in cold regions, and is especially suitable for road, railway slopes and natural slopes in permafrost regions Supporting works. Background technique [0002] With the rapid development of economic construction, various projects in cold regions have been built one after another, and a large number of new slopes have been produced in project construction. The emergence of new slopes inevitably destroys the original surface vegetation, water flow paths, etc., resulting in changes in surface heat transfer conditions. The balance is destroyed, the overall heat intake is greater than the heat expenditure, the temperature of the freeze-thaw active layer rises, and the upper limit of the permafrost drops, which affects the stability of the permafrost slope, and the stab...

AI Technical Summary

Problems solved by technology

[0004] In view of the shortcomings of the above-mentioned existing support technology and based on the principle of protecting the good development of permafrost, the purpose of the present invention is to provide a slope support structure and construction method for active cooling and self-recovery cold areas, so as to solve the cooling effect of the current support structure. Poor, to reduce the damage of frost heave to the support structure, the shortcomings of low vegetation coverage on the slope, to further improve the stability of the slope in cold regions
