Research on the Improvement of Comb Type Telescopic Device&the Installation of Forbidden Zone under the Condition of Non-Stop Navigation in the Airport
In recent years,in the process of airport reconstruction and expansion,there have been many maintenance and reconstruction projects of bridges in the flight area for aircraft taxiing.The expansion device in the bridge structure has always had the problems of high damage frequency and difficult maintenance and replacement.The expansion device of the bridge engineering in the flight area should not only have enough durability under heavy load conditions,but also meet the requirements of convenient maintenance.Once damaged,it needs to be repaired quickly without affecting the normal operation of the airport.Therefore,higher requirements are put forward for this kind of expansion device.By comparing and improving the existing expansion device,this paper studies a heavy-duty rapid replacement expansion device suitable for airport taxiway bridge,which has been put into use in Shanghai Hongqiao Airport.
