上海宝钢一期工程中,许多土方是由日本加藤公司生产的HD-1800型挖掘机完成的。这里就我们使用这种挖掘机的体会,谈点看法一、施工环境宝钢位于长江口南岸,土质松软(属Ⅱ级土)。深度在20m之内的土层大致有两种类型: 1.淤泥质亚粘土,灰色,夹薄层粉砂,厚7m左右; 2.淤泥质粘土,灰色,含少量腐植土,厚度大。土方施工中,基础深度不超过12m,多数 In the Shanghai Baosteel Phase I project, many earthworks were completed by the HD-1800 excavator produced by the Japanese Kato Company. Here we use the experience of such an excavator to talk about the views of a construction environment Baosteel is located on the south bank of the Yangtze River estuary, with soft soil (Class II soil). There are roughly two types of soil layers within 20m depth: 1. Muddy sub-clay, gray, with thin silt, about 7m thick; 2. Muddy clay, gray, with a small amount of humus, large thickness. In the construction of earthworks, the basic depth should not exceed 12m.
