双江口水电站大坝反滤料生产工艺及制备方法浅析

国内外土石坝工程运行期渗流监测资料表明,即使坝体或防渗体局部存在缺陷,甚至存有贯穿性裂缝,只要裂缝下游面反滤层的滤土排水性能良好,其薄弱部位在长期运行中并不会发展、恶化,反而会在坝体排水反滤层的保护下,随着细粒土沿渗流通道沉积、固结,裂缝自行愈合。由此不难得出,保证大坝稳定的关键是保证反滤料的质量。可见反滤料对整个坝体施工中的重要性,现就以双江口砾石土心墙堆石坝飞水岩反滤料加工系统为例,简述一下其生产工艺及方法。

Installation and Debugging of Auto-control System in Fruit Wine Production Line

[Objective] The aim was to test the controlling effect of cleaning steriliza- tion system, material conveying system, and fermentation jar cooling system with equip- ments of fruit wine production line introduced in this study and its auto-control sys- tem field assembled and debugged. [Method] Based on controlling equipment and setting parameters on the configuration interface, the operation state of the control equipments could be real-time monitored and controlled with the help of configura- tion software. [Result] The result showed that the equipment system could reduce the temperature into 12 ℃ with the error of ＋0.5 ℃within 110 minutes when the fermentation temperature is set at 12 ℃ in real production. [Conclusion] The auto- control system of fruit wine production line was easy to be assembled and de- bugged to meet demands of different fruit wine productions.
