Problems solved by technology

[0002] Hydraulic engineering is a general term for various engineering constructions to control, utilize and protect surface and underground water resources and the environment. The construction of hydraulic engineering equipment is inseparable from the use of concrete. When concrete is used, It is necessary to add water and mix all kinds of raw materials evenly to meet the conditions of use. When mixing concrete, traditional mixing equipment cannot effectively dissipate heat from the mixing drum and the concrete inside, resulting in false coagulation of concrete due to excessive temperature. Moreover, the existing concrete mixing equipment does not have the function of weighing and measuring raw materials, which makes it difficult for construction personnel to control the amount of raw materials added, resulting in large errors in raw material ratios, which will lead to poor quality concrete produced
