泵送混凝土是用混凝土泵将搅拌好的塑性混凝土沿着管道输送到浇筑地点的新工艺。它以混凝土泵车等为主要设备,能一次连续完成现场浇筑混凝土的水平、垂直运输和布料,具有效率高、速度快、费用低、机械用量少、节省人工等特点,在一些工业发达国家已成为现场浇筑混凝土的主要方法。上海宝钢一期工程混凝土量达300万立方米,要求平均每年浇筑混凝土75万立方米。为此从日本引进年产50万立方米大型自动化搅拌站两座、三菱DC-S115B型混凝土
Pumped concrete is a new process that uses a concrete pump to transport agitated plastic concrete along a pipeline to a pouring site. It uses concrete pump trucks as the main equipment, and can perform horizontal and vertical transportation and fabrics of on-site pouring concrete at one time. It has the characteristics of high efficiency, high speed, low cost, less mechanical consumption, and labor saving, etc., in some industrial countries. It has become the main method of pouring concrete in the field. The Baosteel Phase I project has a concrete volume of 3 million cubic meters, requiring an average of 750,000 cubic meters of concrete per year. To this end, two large-scale automated mixing plants with an annual output of 500,000 cubic meters and Mitsubishi DC-S115B concrete were imported from Japan.
