AI Technical Summary
The drainage system of existing pile foundation projects in permafrost areas is prone to blockage or failure due to frost damage, which increases the risk of permafrost thawing and settlement and affects the stability of the pile foundation.
The system employs a linkage system consisting of a longitudinal support module, a water diversion module, a temperature measurement module, a heating module, and a control module. By monitoring the temperature and moisture of the frozen soil layer in real time, it automatically adjusts the heating power of the heating module to melt snow and ice, ensuring smooth drainage.
It effectively prevents the thawing and settlement of frozen soil caused by temperature changes, ensuring the long-term stability and reliability of pile foundation structures, and is particularly suitable for frozen soil pile foundation projects in extreme climates.
