Proposal of a brand new Control Approach to Decide the Ground Thermal Regime A brand new structure for Alvelestat Elastase pipeline thaw settlement prevention is proposed in the point of view of active cooling, which might be used not just for ground cooling around the pipeline but also can function as an underground assistance portion for the pipeline. Its structure and working principle are illustrated in Figure five, whose two key elements, the help structure as well as the U-shaped air-ventilated pipe, are described inside the following.3. Proposal of a new Handle Process to Figure out the Ground Thermal Regime A brand new structure for pipeline thaw settlement prevention is proposed from the point of view of active cooling, which may be utilised not only for ground cooling about the pipeline but also can function as an underground assistance part for the pipeline. Its structure five of 14 and working principle are illustrated in Figure five, whose two main components, the support structure and also the U-shaped air-ventilated pipe, are described within the following.Water 2021, 13,Figure five.

The U-shaped air-ventilated The U-shaped air-ventilated pipe (the cooling structure), shown inin Figure 5b, in(the cooling structure), shown Figure 5b, is is stalled on the help plate for cooling. Dual elbows from the air-ventilated pipe pipe are installed on the help plate for cooling. Dual elbows with the air-ventilatedare placed at different heights plus the dual principles of cooling are adopted beneath under various placed at distinctive heights plus the dual principles of cooling are adopteddifferent situations.
