机制砂生产线根据工艺分为两种:干法制砂和湿法制砂,20世纪我国采用的基本上都是湿法制砂工艺,随着生产水平的提高,加之对国外水利工程案例的借鉴,经过一段时间的摸索和实践以后,干法制砂日益成熟,已经成为当前水利工程施工的一项重要技术手段。文章结合两个工程实例对干法制砂技术进行了分析和探讨,并指出了在干法制砂时应当注意的一些问题,希望能够为我国水利工程制砂技术提供一些参考和意见。
Sand production line according to the process is divided into two types: dry sand and wet sand, the 20th century, our country are basically wet sand making process, with the improvement of production levels, combined with the case of foreign water conservancy projects, after a period of After time exploration and practice, the dry sand has become more and more mature, and it has become an important technical means for the current construction of water conservancy projects. The paper analyzes and discusses the dry sand making technology with two engineering examples and points out some problems that should be paid attention to in the dry sand making process. It is hoped that this article can provide some references and suggestions for the sand making technology of water conservancy projects in our country.
