重庆市万州(区)移民开发区地处举世瞩目的长江三峡工程库区腹心地带。 如此规模浩大的移民迁建工程需要大量的建筑墙体材料。但随着水位的上涨,该区的主要建筑墙体材料灰砂将因淹没而基本消失。因此,必须因地制宜发展新型建筑墙体材料。国家科技部根据库区的资源条件,下达了“混凝土小型空心砌块生产技术研究及示范工程建设”重点科研项目。经过3年的工作,全面完成了“项目”
The Chongqing Wanzhou (District) Immigration Development Zone is located in the heart of the Yangtze River Three Gorges reservoir area, which attracts worldwide attention. Such a large-scale resettlement project requires a large amount of building wall materials. However, as the water level rises, the lime sand of the main building wall material in the area will disappear due to submergence. Therefore, new types of building wall materials must be developed according to local conditions. According to the resource conditions of the reservoir area, the Ministry of Science and Technology issued a key scientific research project of “Research and Production of Concrete Small Hollow Block Production Technology and Demonstration Projects”. After 3 years of work, the project has been fully completed.
