1980年7月22～26日,上海市建工局特约日本石川岛重工业株式社会(IHI)作泵送砼至48公尺垂直高度示范表演。IHI设计工程师边见先生和施工工程师安田先生也应邀来沪指导,边见和安田先生还对更高高度的泵送技术进行了经验传教。现就lpF—75B型泵泵送至100公尺左右高度的有关施工要领结合上海的施工实际叙述如下: 上海泵送商品混凝土的坍落度一般到现场要求不小于8厘米、最大碎石粒径不大于40毫
From July 22 to July 26, 1980, the Shanghai Municipal Construction Industry Bureau specially commissioned the Japan Ishikawajima Heavy Industries and Plants Society (IHI) to perform a vertical demonstration at a height of 48 meters. IHI design engineer Mr. Norihama and construction engineer Mr. Yasuda were also invited to Shanghai for guidance. Mr. Kishimi Kazumi and Mr. Yasuda also delivered experience on higher-level pumping technology. Now the construction of the lpF-75B pump pump to the height of about 100 meters combined with the actual construction of Shanghai is described as follows: The slump of Shanghai pumped commercial concrete is generally required to be not less than 8 cm on site and the maximum size of the crushed stone Not more than 40 millimeters
