The construction method of the modular maintenance corridor of the lighting system of the navigation aid tower

Abstract

The invention relates to a construction method for a modular maintenance corridor of a lighting system of a navigation aid tower. The maintenance corridor includes a navigation aid lighthouse and a modular corridor component, and the modular corridor component is a truss structure module on which a There are hoisting structural plates, bottom closed steel gratings and side safety protection plates; the components of the modular corridor are assembled with each other by bolts; the construction method of the corridor includes setting auxiliary masts on the top of the lighthouse, erecting horizontal steel cables, The process of hoisting steel cables and hoisting components of modular corridors. The invention effectively reduces the construction cost of the airport navigation lighting system and its inspection and maintenance system, can effectively and timely ensure the maintenance of the navigation lighting system and the personal safety of maintenance personnel, thereby ensuring the safety of aircraft take-off and landing.

[0002] With the rapid development of the air traffic industry, airport infrastructure is the basic condition for the development of air traffic. According to the requirements of the International Civil Aviation Organization for airport construction design specifications, navigation lights are indispensable for every airport as an auxiliary equipment for safe take-off and landing of aircraft. For construction projects, my country has a vast territory and complex topography. For plain areas, it is sufficient to directly install the navigation lighting system on the ground. However, due to terrain problems in hills and mountainous areas, a large amount of foundation backfilling is required to ensure the straight line level of the navigation lights to achieve Aircraft take-off and landing standards require that this will cause huge investment. In order to ensure the aircraft take-off and landing labeling requirements and reduce construction costs, navigation aid lighthouses have emerged as the times require. After practical application, they have been recognized by the Civil Aviation Administration and the National Development and Reform Commission. The navigation aid lighthouse is a towering steel structure. According to the different airport construction sites and the standard requirement of 30 meters between navigation aid lights, its height ranges from a few meters to over 100 meters. Compared with the lighting system built on flat ground, maintenance becomes a technical difficulty.

The existing technology uses the easy-to-break pole lifting system of the navigation lighthouse to maintain the lighting system. Firstly, its operating cost is high, and the easy-to-fold pole lifting system of the navigation lighthouse also has maintenance requirements; secondly, for each lighthouse, maintenance personnel Both need to go through the process of going up and down, which is time-consuming and labor-intensive, and there are potential safety hazards
