Bionic hydrophobic-hydrophilic composite heat pipe geotextile protective member

Abstract

The application provides a bionic hydrophobic-hydrophilic composite heat pipe geotechnical protection component, and is suitable for the fields of geological disaster prevention and geotechnological protection. The component comprises a bionic hydrophobic-hydrophilic composite layer, has staggered hydrophilic parts and hydrophobic parts, the hydrophilic guide area of the hydrophilic part is connected with the hydrophilic nucleation area through a fiber continuous structure or a pore communication structure, the hydrophilic nucleation area of the hydrophilic part is used for nucleation and condensation of water vapor in soil, the hydrophobic part is used for promoting condensate water to be detached from the hydrophilic nucleation area and migrate to the hydrophilic guide area, the hydrophilic guide area is used for receiving the condensate water detached from the hydrophobic part and gathering liquid water, a heat conduction layer is arranged on one side of the bionic hydrophobic-hydrophilic composite layer and extends to the inside of the soil, and a drainage backflow module is arranged in communication with the hydrophilic guide area, receives the gathered liquid water and directionally drains the liquid water. In this way, the synergy of water migration regulation and temperature regulation and the centralized recovery and utilization of liquid water are realized.
