在建筑施工中,混凝土搅拌是一项操作繁重的作业。为了保证工程质量、减轻劳动强度、提高劳动生产率、加快施工速度,必须采用成套的机械装备,实行施工机械化。国外在分散的、少量的混凝土搅拌作业中,广泛使用中小型机械。其机械化自动化程度各不相同,机械配套情况如下:1.上料设备:砂石集料的上料,国外多 Concrete mixing is a heavy operation in building construction. In order to ensure project quality, reduce labor intensity, increase labor productivity, and speed up construction, complete sets of mechanical equipment must be used to implement construction mechanization. In the dispersed and small amount of concrete mixing operations abroad, small and medium-sized machines are widely used. The degree of mechanization automation is different, and the conditions of the mechanical support are as follows: 1. Feeding equipment: feeding of sand aggregate, foreign
