装配式水泥混凝土道面在机场抢修中的应用

Application of Fabricated Cement Concrete Pavement in Airport Repair

水泥道面是国内机场应用最为广泛的道面类型,随着大量机场水泥道面进入维护期,水泥道面损坏后修复困难的问题也越来越凸显。装配式水泥混凝土道面具有“集中预制、分散安装”的特点,具有快速、环境能力适应强、经济的优点,是现有水泥道面维护的良好解决方案。现调研了国内外装配式水泥混凝土道面技术的研究现状,介绍了在浦东机场、伊春机场的成功应用案例;指出了应用在机场道面抢修的主要施工工艺和技术要求,提出了装配式水泥道面技术难点在于保证板底的充分填充、道面接缝传力的恢复和道面表面的平整度;经分析认为开发相应的专用设备、实现道面技术的工业化方可解决装配式水泥混凝土道面技术实施的难题。

Cement pavement is the most widely used pavement type in domestic airports.With a large number of airport cement pavement entering the maintenance period,the problems of difficult repair after cement pavement damage is becoming more and more prominent.The fabricated cement concrete pavement has the characteristics of centralized prefabrication and decentralized installation,and has the advantages of fast and strong environmental adaptability and economy,which is a good solution for the maintenance of the existing cement pavement.The research status of fabricated cement concrete pavement technologies at home and abroad are investigated and studied.The successful application cases in Pudong Airport and Yichun Airport are introduced.The main construction technology and technical requirements of its application in the airport pavement repair are pointed out.It is proposed that the technical difficulty of the fabricated cement pavement is to ensure the full filling of the slab bottom,the recovery of the force transmission at the pavement joints and the smoothness of the pavement surface.Through the analysis,it is believed that the development of relevant special equipment and the realization of pavement technology industrialization can solve the problems in the implementation of fabricated cement concrete pavement technology.
