With the vigorous development of modernization, industrialization and urbanization in my country, the scale of economic construction is also expanding rapidly. With the rapid development of construction, the development and use of tunnels are becoming more and more frequent. Due to the influence of construction materials and geological structures, these tunnel pavements or walls often develop cracks to a certain extent, leading to dangerous conditions for tunnel traffic. Different additives need to be added to the concrete for different repair methods to give the repair concrete specific properties. The conventional operation is to mix the additives on-site by adding them to the concrete and stirring to achieve the purpose of mixing. However, there are problems such as uneven mixing or long mixing time to achieve uniform mixing, which prolongs the repair time and reduces the repair efficiency. Utility Model Content
