Description

Technical Field

[0001] The utility model belongs to the technical field of geological disaster monitoring equipment and facilities, and in particular relates to a navigation lamp with an airport pavement deformation monitoring function. Background Art

[0002] An airport runway is an extra-long strip of area within an airport used for aircraft to take off or land. An airport taxiway is a passage for aircraft to taxi on the ground, connecting the airport's flight area, terminal area, aircraft parking area, maintenance area and supply area. Airport runways and taxiways are the most important facilities in an airport, and are related to the airport's operating costs and the property safety of aircraft and ground facilities.

[0003] A large number of airports in China are built in areas with complex geological conditions, including those crossing earthquake fault zones, those located in areas with significant geological settlement, those with dense lakes and ponds and soft foundations, and those with strong loess collapsibility and large differences in filling and excavation. In recent years, most of the airports built have been built through methods such as cutting peaks and filling valleys (Sichuan Panzhihua Baoanying Airport), moving mountains and reclaiming land (Hong Kong Chek Lap Kok International Airport), and reef reclamation (South China Sea Meiji Reef Airport). Such airports have the potential for geological disasters. In 2012, the second runway of Chengdu Shuangliu International Airport settled and the pavement was partially deformed, resulting in suspension of flights for construction. The main manifestations were local uplift and most of the uneven settlement, which was mainly concentrated near the centerline and shoulders of the runway. A total of 46 pavement panels were involved, of which 5 had a settlement of more than 10 cm.

[0004] Obviously, it is necessary and urgent to implement geological monitoring on airport runways and their surroundings. In recent years, the geological subsidence monitoring method based on the Beidou satellite navigation system has begun to be applied to airports due to its advantages of high absolute monitoring accuracy and all-weather real-time monitoring, such as Beijing Capital International Airport, Huahu Airport in Ezhou, Hubei, and Dingri Airport in Shigatse, Tibet. However, the size and weight of the Beidou satellite navigation system geological subsidence monitoring (hereinafter referred to as Beidou monitoring) equipment are usually large, and are not suitable for installation and use on runways and their vicinity.

[0005] For example, the patent application document with Chinese utility model patent application number 201910755708.0 discloses an airport runway settlement monitoring system, in which multiple settlement monitoring points are arranged in the runway foundation, and a magnetostrictive liquid differential pressure type static level is buried in each settlement monitoring point. A settlement base point is arranged on the side of the runway foundation, and a magnetostrictive liquid differential pressure type static level is also installed at the settlement base point. The magnetostrictive liquid differential pressure type static level at each settlement monitoring point is connected to the magnetostrictive liquid differential pressure type static level at the settlement base point through a liquid connecting pipe, and the magnetostrictive liquid differential pressure type static level at each settlement monitoring point is connected to the magnetostrictive liquid differential pressure type static level at the settlement base point through a gas connecting pipe, and all the data cables of the magnetostrictive liquid differential pressure type static level are summarized and led out to the data collector near the settlement base point through the pre-buried threading pipe.

[0006] The above-mentioned prior art adopts a method of setting a plurality of settlement monitoring points in the runway foundation and burying a static level to monitor the settlement, which makes the construction process and subsequent maintenance work of the runway more complicated.

[0007] Based on the above technical problems existing in the prior art, the utility model proposes a navigation light with airport pavement deformation monitoring function. Utility Model Content
