Perpetually frozen soil roadbed hydrothermal regulation and control system with comprehensive climate adaptability
The invention discloses a comprehensive climate adaptability permanent frozen soil roadbed hydrothermal regulation and control system, the system comprises a wind power driven forced convection cooling plate, a wind power driving device, a heat insulation layer and a capillary retardation covering layer, the wind power driven forced convection cooling plate is laid at the bottom of a roadbed, and a slender channel is arranged in the plate; the wind power driving device is connected with a slender channel in the wind power driving forced convection cooling plate, and a liquid working medium is driven by a pump to flow in the slender channel, so that forced convection is realized; the heat insulation layer is laid at the upper part of the wind-driven forced convection cooling plate and is used for preventing high heat in summer from being transferred into the roadbed and the permafrost; the capillary retardation covering layer is laid on the side slope, surface water is effectively isolated according to the principle of a capillary barrier, and therefore the roadbed is in a dry state. According to the invention, annual climate adaptability can be realized, and runoff on the road surface and on the surface can be prevented from intruding into the roadbed, so that differential settlement of the roadbed is inhibited to the greatest extent.
本发明公开了一种综合气候适应性永久冻土路基水热调控系统，所述系统包括风力驱动强制对流冷却板、风力驱动装置、隔热保温层和毛细阻滞覆盖层，其中：所述风力驱动强制对流冷却板铺设在路基底部，板内设置有细长通道；所述风力驱动装置与风力驱动强制对流冷却板内部的细长通道相连接，通过泵驱动液态工质在细长通道内流动，从而实现强制对流；所述隔热保温层铺设在风力驱动强制对流冷却板上部，用以阻止夏季高热向路基与多年冻土内部传递；所述毛细阻滞覆盖层铺设在边坡处，利用毛细屏障的原理，有效隔离地表水，从而使路基处于干燥状态。本发明能够实现全年气候适应性，可以阻止路表及地面径流侵入路基内部，从而最大程度地抑制路基不均匀沉降。
