Background technique

In engineering construction, brick walls can separate spaces and play a load-bearing and maintenance role. When building a brick wall, it usually includes three actions: shoveling, laying ash, and laying bricks, that is, the construction workers use tools such as ash shovels and ash knives to lay mortar. The construction personnel rely on personal experience to control the uniformity and flatness of the mortar thickness of the mortar joints, the construction efficiency is low, and the masonry quality of the wall is difficult to guarantee. When building walls, there is also a brick-knife plastering method, which also refers to the full-knife ash method. For building empty bucket walls, window sills, etc., the mortar used is required to have a high consistency and good viscosity.
