Ultraviolet sterilization information provision system of baggage carts and arriving baggage for airports

In this study, we develop a system to provide information on the sterilization of baggage carts and arriving passenger baggage to airport (Hereafter referred as arrival baggage) by using ultraviolet (UV) sterilization and information communication technology as border quarantine measures at airports. This system sterilizes arrival baggage and baggage carts by UV irradiation, and allows passengers to easily view the sterilization information recognized by radio frequency indentation technology. This is to provide safety and security not only to passengers, but also to staff, who may come into direct contact with the arrival baggage, of airport, airline, customs, and so on. In addition, the passengers can be provided with baggage tracking information, such as the current location and estimated delivering time of the baggage. This makes it possible to keep social distancing at baggage claims as an infection prevention. Furthermore, we verify the feasibility of the developed system and identify the issues to be addressed for its practical application through a demonstration of proof of concept at Central Japan International Airport.

Examination of predictability of drifting debris accumulation point in Ise Bay by Artificial Neural Network method

In the Ise Bay, there is a problem of drifting debris. This study examines the validity to use an Artificial Neural Network (ANN) for the prediction of collection position of the drifting debris. The ANN model predicting the positions of debris generation and debris accumulation is constructed by checking suitable input data and ANN parameters and transfer function. The resulting ANN gives good predictions: 1) The fit ratio of the drifting debris generation positions is 83%; 2) The fit ratio of drifting debris accumulation positions is more than 50%; and 3) In front of Yokkaichi city and southward of Centrair (The central Japan International Airport) are the main places where drifting debris gathers.

中部国際空港エプロン舗装に使用したコンクリートの収縮特性

For the purpose of contributing to the jointing plan for the apron pavements of Central Japan International Airport, various tests were conducted in regards to concrete mixed with pulverized blast-furnace slag. Relationships between the amount mixture of pulverized blast-furnace slag, and both the mechanical and shrinkage properties were obtained. Further, the resistance of concrete to cracking was reviewed through stress analysis. In addition, we investigated the conditions in which cracking is induced at the joints of concrete slabs at the actual pavement worksites. These results were then verified using stress analysis.From the stress analyses results, it was found that cracking by shrinkage was induced, where joint spacing was equivalent to that of cement without pulverized blast-furnace slag, when using 40% pulverized blast-furnace slag mixed cement. In relation, results from a follow-up survey concerning with induced cracking in actual concrete slabs, demonstrated a consistency with the stress analysis results.

Quality control in Central Japan International Airport construction

Recently, a pneumatic flow mixing method has been developed for sea reclamation and land development, in which soft soil is mixed with a relatively small amount of stabilising agent in a transporting pipe. The soil mixture forms several separated mud plugs in the pipe, and is thoroughly mixed with the help of turbulent flow during transportation. This method was adopted to construct part of a man-made island for the Central Japan International Airport at the Ise Bay area in Nagoya. In the construction project, a total of 8.6 million m3 of dredged soil was stabilised by the method for sea reclamation. During the construction, quality control and assurance of manufacturing the treated soil were carried out with an automated control system and laboratory tests on sampled soils. In this paper, the quality control system developed in this project and the quality assurance of the improved ground are described in detail. Récemment, une méthode de mixage á flux pneumatique a été développée pour récupérer des terrains sur la mer et les développer, méthode consistant à mélanger un sol tendre avec une quantité relativement faible d'agents stabilisants dans une canalisation de transport. Le mélange de terre forme plusieurs bouchons de boue séparés dans la canalisation et se trouve mélangé à l'aide d'un flux turbulent pendant le transport. Cette méthode a été adoptée pour construire une partie d'une île artificielle pour l'aéroport international Central Japan dans la région de Ise Bay ´ Nagoya. Dans le projet de construction, un total de 8,6 millions de m3 de sol draguéa été stabilisé par cette méthode. Pendant la construction, le contrîle et l'assurance qualité concernant la fabrication de sol traité ont été effectués par un systéme de contrîle automatisé et des essais en laboratoire suré chantillons de sol. Dans cet exposé, nous décrivons en détail le systéme de contrîle de la qualité développé dans ce projet ainsi que l´assurance qualité du sol amélioré.

NEW DESIGN AND TECHNOLOGY TOWARDS AN ECO-FRIENDLY AIRPORT

As a means of transportation to connect the world, in particular, as a means of international human exchange, the airplane and the airport are bearing indispensable roles. The Central Japan International Airport “Centrair”, to be opened as an important hub airport in February, 2005, is now under construction over the Ise Bay, off the coast of the city of Tokoname, Aichi Pref. In charge of construction of this airport, from the early stage of the basic design, via construction, to its employment stage, “Centrair” has considered and will consider its harmonization with surrounding environment by reducing various environmental loads. In this session, we will introduce new attempts, which we have taken so far, to realize it. We hope the following presentations will help further development of the new technology.

Development of a pneumatic flow mixing method and its application to Central Japan International Airport construction

A pneumatic flow mixing method has been developed for sea reclamation and land development, in which dredged clay is mixed with a relatively small amount of cement in a transporting pipe. The soil mixture forms several separated mud-plugs in the pipe, and is thoroughly mixed by means of turbulent flow during the transporting. The mixture, transported and deposited at the reclamation site, rapidly gains relatively large strength, so that no additional soil improvement is usually required. This method is expected to provide economical and rapid construction for sea reclamation, and is being applied to the construction of a man-made island for Central Japan International Airport in Nagoya. The construction project started in 2001 and will be completed in 2005, by about 8·2 million m3 of dredged soil will have been stabilised by the method. In this paper, the mechanical properties of the treated soil, the method of execution, and its application to the airport construction project are described in detail. Récemment, une méthode de mixage pneumatique a été mise au point pour reprendre des terrains sur la mer et les développer : l'argile draguée est mélangée avec une quantité relativement faible de ciment dans une conduite de transport. La mixture de sol forme plusieurs bouchons de boue séparés dans le tuyau, mixture qui se trouve bien mélangée au moyen d'un écoulement turbulent pendant le transport. Le mélange, transporté et déposé sur le site récupéré, gagne rapidement une résistance relativement élevée si bien qu'aucune amélioration supplémentaire du sol n'est en principe nécessaire. Cette méthode devrait permettre de construire rapidement et économiquement sur les terrains récupérés; elle est utilisée dans la construction d'une île artificielle pour l'aéroport international de Nagoya au Japon. Le chantier a commencé en 2001 et les travaux devront s'achever en 2005. D'ici là, près de 8,2 millions de mètres cubes de sol dragué auront été stabilisés par cette méthode. Dans cet article, nous décrivons en détail les propriétés mécaniques du sol traité, la technique d'exécution de la méthode et son application à la construction de l'aéroport.
