最近在长江三峡工地上,新建了一个混凝土搅拌系统。该系统中的主体设备是两座混凝土搅拌楼,一座是从日本进口的,生产能力为324m~3/h,另一座为国产设备,生产能力为240m~3/h。这两台设备基本可代表目前国内外混凝土搅拌楼的制造水平。在安装试运行中,人们不免对近在咫尺的洋货与国货时有评头论足之声,既谈到了国货的差距,也看到了国货的进步与发展前景。下面谈谈我的浅见。 一、钢结构部分 钢结构是搅拌楼的骨架,支承载荷的主体。其结构的合理与否,直接影响整楼的安全性、经济性、安装进度及使用寿命。日本搅拌楼是以6根直径近1m的圆形管
Recently, a new concrete mixing system was built on the Three Gorges Project site in the Yangtze River. The main equipment in this system is two concrete mixing buildings, one imported from Japan with a production capacity of 324m 3 / h and a domestic equipment of 240m 3 / h. The two devices can basically represent the current level of manufacturing of concrete mixing at home and abroad. In the installation and trial operation, people can not help but feel uncomfortable talking about foreign goods and domestic products in close proximity. They not only talked about the gap between domestic products and goods, but also saw the progress and development prospects of domestic products. Here to talk about my humble opinion. First, the steel part of the steel structure is the skeleton of the mixing floor, supporting the main load. Its structure is reasonable or not, a direct impact on the safety of building, economy, installation progress and service life. Japan mixing tower is based on six diameter of 1m round tube
