AI Technical Summary
Existing freezing construction equipment cannot achieve precise and adaptive adjustment during the freezing wall thickness maintenance stage, resulting in energy waste, frost heave risk, and freezing wall thickness control failure. The main reasons are the lack of precise cold demand perception, outdated control logic, crude adjustment of actuators, and lack of integrated formation parameter input.
Design a frozen wall thickness control device based on cooling demand. The device acquires the frozen wall status and formation parameters in real time through a sensor system. Combined with a controller based on a cooling demand calculation model, it can accurately adjust the cooling output of the freezing pipe to form a closed-loop control system to maintain the stability of the frozen wall thickness.
It achieves precise maintenance of frozen wall thickness, reduces the risk of frost heave, significantly saves energy, and can adaptively respond to formation changes, improving the stability and safety of frozen wall thickness.
