我公司近几年来承担的工业建筑施工项目,都为中小型冶金厂矿,混凝土量不大,一般在3～5万米~3。建设周期为两年左右。在现场生产的混凝土,其后台上料基本上是靠人工,用工多,劳动强度大。为了改变施工落后面貌,提高机械化施工水平,加快施工进度,我公司第三工程处三○四队,在学习兄弟单位先进经验的基础上,于1977年建 The industrial construction projects undertaken by our company in recent years are all small- and medium-sized metallurgical factories and mines. The amount of concrete is small, generally 3 to 50,000 meters~3. The construction period is about two years. The concrete produced at the scene is basically based on artificial labor, labor and labor intensity. In order to change the backwardness of construction, improve the level of mechanized construction, and speed up the construction progress, the 303 team of the 3rd Engineering Office of our company was established in 1977 on the basis of the advanced experience of the siblings.
