Parallel ventilation pipe structure suitable for airport runway in permafrost region
The invention provides a parallel ventilation pipe structure suitable for an airport runway in a permafrost region. The parallel ventilation pipe structure is composed of a first pipeline and a second pipeline which are made of reinforced concrete materials, a plurality of through-wall ventilation pipes can be connected in parallel, and a road base close to one side of an airport runway adopts a steel plate net containing a large number of small ventilation holes. A vertical side ditch is arranged at the starting point of the first pipeline, the terminal point of the second pipeline and close to an inlet and an outlet of each through-wall ventilation pipe, and a detachable closing device is installed. The device is applied to the airport runway composite road base of the through-wall ventilation pipe-block gravel layer, the flowing range of cold air in the gravel layer can be expanded, the convective heat exchange effect of the cold air and the gravel layer is enhanced, rising of the upper limit of the underlying frozen soil layer of the airport runway road base in the permafrost region is effectively restrained, and the temperature stability of the frozen soil road base is kept.
本发明提供一种适用于多年冻土地区机场跑道的并联通风管结构。并联通风管结构由钢筋混凝土材质的一号管道和二号管道组成，可实现若干根透壁通风管并联，靠近机场跑道一侧道基采用含大量可透风小孔的钢板网，在一号管道起点处、二号管道终点处、靠近每根透壁通风管进出口处设置一条竖直边沟并安装可拆卸的闭合装置。本发明专利应用在透壁通风管‑块碎石层的机场跑道复合道基，可扩大冷空气在碎石层中流动范围，增强冷空气与碎石层对流换热效应，有效抑制多年冻土区机场跑道道基下伏冻土层上限的抬升，保持冻土道基温度稳定性。
