Ventilation cooling device suitable for permafrost region and construction method
The ventilation cooling device comprises an outer pipe and an inner pipe which are arranged in a nested mode, the outer pipe and the inner pipe jointly form a first channel and a second channel which are communicated at the lower end, and a gravity flap valve is arranged below the inner pipe, can turn over under the gravity effect of a heavy object and drives the heavy object to fall into the lower space; according to the device, cold air circulation convection is guided by arranging the channel, the cooling effect is achieved on the periphery of the outer pipe, and then frozen soil is cooled; by arranging the gravity flap valve, the length of a communicating opening below the inner pipe can be reduced, air flow is accelerated, and the heat dissipation and cold conduction efficiency is improved; accumulated ice or foreign matters in the channel can be quickly discharged, so that the channel is prevented from being blocked; in addition, the device is small in occupied area, convenient to embed and install, capable of being constructed after construction and suitable for reinforcement and repair of in-service roads. According to the construction method, construction of the device can be efficiently and safely completed, perturbation to frozen soil is small, and the construction method is suitable for high and cold zones.
本发明公开了一种适用于多年冻土区的通风冷却装置及施工方法，装置包括嵌套设置的外管和内管，两者共同形成在下端贯通的第一和第二通道，内管的下方设置有重力翻板阀，其能够在重物的重力作用下翻转，并带动重物落入下方空间；本发明所述装置通过设置通道引导冷空气循环对流，在外管周边产生降温效果，进而对冻土进行冷却；通过设置重力翻板阀，不仅能减小内管下方的连通口长度，加速空气流动，提高散热导冷效率；还能将通道内的积冰或异物快速排出，避免通道堵塞；此外，本装置占地面积小，埋设安装方便且能够工后施工，适用于在役公路的补强修复；本发明所述施工方法，能够高效安全地完成上述装置的施工，且对冻土扰动小，适用于高寒地带。
