The invention provides a
permafrost slope sunshading
refrigeration anchoring structure and a construction method. The
permafrost slope sunshading
refrigeration anchoring structure comprises an anchoring
system and a
refrigeration system; the anchoring
system comprises a frame, a hollow anchor
pipe, an anchorage device and a backing plate; the hollow anchor
pipe is formed by connecting a thick pipeand a thin
pipe, and the anchorage device and the backing plate enables the front end of the anchor pipe to be anchored to the frame, and
slurry anchors the rear end of the anchor pipe in a soil body. The refrigeration system includes a solar panel, a refrigeration sheet, a
voltage controller, a temperature sensor, a
temperature control switch and an unpowered ventilator; the solar panel is fixedto the frame, the refrigeration sheet is arranged in the thick pipe in a sleeved mode and the cold surface of the refrigeration sheet is tightly attached to the pipe wall of the thick pipe, and the unpowered ventilator sleeves the front end of the thick pipe; the
temperature control switch controls the operation and disconnection of the refrigeration sheet, when the temperature of the soil body is higher than the working switching temperature of the switch, the stitch closes the refrigeration sheet to absorb heat, and the temperature of the surrounding soil body is reduced. The
permafrost slope sunshading refrigeration anchoring structure is simple in structure, high in
operability and good in cooling, anchoring and long-term service performance, and provides a new idea for solving the problems of slope freezing and thawing
instability and upper limit degradation.
