交通运输部2013年6月20日公布了《国家公路网规划(2013年—2030年)》。据此,到2030年,我国国家公路网总规模约40万km,为此将投入约4.7万亿元。截止到2012年年底,国家级干线公路通车里程17.3万km,这意味着,未来十几年我国新建、改造公路将达到约23万km,这势必会带动公路养护机械的发展。路面冷铣刨机作为道路机械化养护必不可少的主要设备之一,主要用于公路、城市道路、机场、广场等设施中已损坏的沥青、水泥混凝土面层及路基稳定层的铣刨清除作业,如路面拥包、油浪、网纹和车辙的清除,还可对路面进行快速防滑拉毛作业。作为高效的路面维修与养护设备,路面冷铣刨机近年来得到了广泛应用。本期我们将遴选6款铣刨宽度为1 m的冷铣刨机,分别从动力、技术性能以及配置等方面进行全方位的剖析和介绍,希望大家对这些产品有更深入的了解。
The Ministry of Transport announced the “National Highway Network Plan (2013-2030)” on June 20, 2013. Accordingly, by 2030, the total size of China’s national road network will be about 400,000 km, and about 4.7 trillion yuan will be invested in this. As of the end of 2012, the national trunk highway mileage was 173,000 km, which means that in the next 10 years, the number of new and reconstructed roads in the country will reach about 230,000 km, which will inevitably drive the development of highway maintenance machinery. Road surface cold milling machine is one of the main equipment necessary for mechanized road maintenance. It is mainly used for the removal of damaged asphalt, cement concrete surface layer and roadbed stability layer in highways, urban roads, airports, squares and other facilities , Such as pavement package, oil waves, netting and rut removal, but also on the road for quick anti-skid paving operation. As an efficient pavement maintenance and maintenance equipment, pavement cold milling machine has been widely used in recent years. In this issue, we will select 6 cold milling machines with a milling width of 1 m to conduct a full range of analysis and introduction from the aspects of power, technical performance and configuration, etc., and hope everyone will have a deeper understanding of these products.
