为使我国混凝土预冷工程在技术上达到较为先进的水平,水电部杭州机械设计研究所从1983年开始,对气力输送片冰技术不断进行研究探索,于1986年9月按照实用条件试验成功。为对此项科研试验项目进行一次评审,水电部水电建设局于1986年10月在试验现场主持召开了“气力输送片冰技术评审会”。参加会议的有水电部机械修造公司和有关单位制冷方面的专家、技术人员共38名代表。
In order to make China’s concrete pre-cooling project in the technology to achieve a more advanced level, the Ministry of MOH Hangzhou Institute of Mechanical Design from 1983 onwards, the continuous transmission of ice sheet transport technology to explore, in September 1986 in accordance with the practical conditions of the successful trial. In order to conduct a review on this pilot project, the Hydropower Construction Bureau of the Ministry of Electricity and Water was hosted by the Hydropower Construction Bureau of the Ministry of Electric Power and Electricity in October 1986 at the trial site of the Pneumatic Technology Review Meeting. A total of 38 representatives of experts and technicians from Ministry of Machinery and Equipment of the Ministry of Water Resources and relevant departments for refrigeration attended the meeting.
