Embodiment Construction

[0017] The airport runway structure applicable to permafrost regions provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 As shown, the airport runway structure applicable to the permafrost region provided by the present invention comprises a runway pavement structure layer 1, a thermal insulation layer 2, a crushed stone layer 3, a side ditch 4, a blower 5 and a closing device 6; wherein the crushed stone layer 3. The heat insulation layer 2 and the runway pavement structure layer 1 are successively laid on the permafrost foundation located in the airport runway area from bottom to top; the inner parts of the grass surface area on both sides of the airport runway respectively form a lower part connected with the gravel layer 3 The side ditch 4 that passes through and extends longitudinally along the airport runway; a closing device 6 is detachably installed at the ...

Abstract

An airport runway structure applicable to permafrost regions comprises a runway pavement structure layer, a heat-insulating layer, a gravel layer, side ditches, blast blowers and closing devices. Theairport runway structure has the effects as follows: all components are positioned inside a frozen soil foundation under an airport runway and do not occupy the ground area of a flight area, so that the problem that the components occupy the flight area due to exposure to the ground surface is avoided very well, and thus influence on takeoff of airplanes and normal operation of an airport can be avoided; the heat-insulating layer laid under the runway pavement structure layer can prevent external heat from entering the frozen soil foundation; the gravel layer itself has a certain heat-insulating effect, so that the gravel layer under the heat-insulating layer can further prevent heat passing through the heat-insulating layer from entering the frozen soil foundation; and the airport runwaystructure can prevent the external heat from entering the frozen soil foundation, so that the stability of the temperature and the strength of the frozen soil foundation can be maintained.

Description

technical field [0001] The invention belongs to the technical field of airport construction in permafrost regions, and in particular relates to an airport runway structure suitable for permafrost regions. Background technique [0002] my country's seasonally frozen soil and permafrost areas account for 75% of the country's land area, of which permafrost areas account for 22.3% of the country's land area, mainly distributed in the Northeast and the Qinghai-Tibet Plateau. Moreover, in the future, airport construction will be carried out successively in permafrost regions and some seasonal permafrost regions, and dozens of small feeder and commuter airports will be added successively by 2020. Many feeder airports will be built in the permafrost areas of Heilongjiang, Qinghai and Tibet, so the construction of airport runways will not avoid the problem of permafrost engineering. Moreover, human engineering activities will largely change the original heat exchange conditions of t...
