Problems solved by technology
In areas with good geological conditions, it can meet the requirements of taxiways; but in areas where sea reclamation promotes siltation, the thickness of the weak soil layer is large, and it has unfavorable conditions such as high compressibility, large deformation, low strength, poor water permeability, and long history of deformation stability. , the differential settlement between the taxiway bridge and the aircraft taxiway, it is difficult to meet the basic functional requirements of the taxiway, and it is unsafe to use

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] An airport taxiway communication channel, the communication channel 1 is a box structure, including the bottom plate 2, the side wall 3 and the top plate 4, it is characterized in that the transition area 5 is within 30m on both sides of the communication channel 1, and the communication channel 1 is below and The foundation below the airport taxiway in the transition area 5 is equipped with a three-axis cement-soil mixing pile 7, and the bottom plate 2 of the communication channel 1 is placed on the foundation reinforced by the tri-axial cement-soil mixing pile 7 below it, and the box body of the communication channel 1 There are boards 8 on both sides of the structure, the ends of the boards 8 rest on the corbels of the side walls 3, and the rest rest on the foundation reinforced by the triaxial cement-soil mixing pile 7. Among them, the length...

Abstract
The invention discloses a liaison channel under airport taxiways, characterized in that it adopts a box body structure, and three-shaft cement blending piles are arranged in the groundsills under the airport taxiways below the box body structure and in the 20m-40m range on its two sides, there are attachment straps on its two sides, and the attachment straps are connected with the groundsills on its two sides, provided with three-shaft cement blending piles. In the specific engineering environment of airport, it reinforces the groundsills by three-shaft cement blending piles and can assure the strict differential settlement requirements of the airport.
Description
Technical field: [0001] The invention relates to the field of airport construction, in particular to an airport taxiway under-communication passage and a construction method thereof. Background technique: [0002] During the service period of the aircraft taxiway, it is the key to ensure the integrity of the pavement structure and the smooth running of the aircraft at high speeds without exceeding the specified settlement and uneven settlement. A large airport may have two or more airstrips. At present, the traditional domestic solution to the conflict between the landside traffic and the airside traffic in the airport is to build an overpass bridge, and realize the flight area through the taxiway bridge. between aircraft operations. Affected by the overall planning, some newly-built airports cannot adopt the form of overpass bridges, and must pass under the taxiway, and adopt the scheme of going down the overpass underground. [0003] The design concept of the underpass t...
