Background

With the development of concrete construction technology, the application of a plastering machine is more and more extensive, the application industry and working conditions are more and more complicated, under some special working conditions (such as cambered surfaces), the application of a conventional plastering machine is greatly limited, only manual plastering can be adopted, the working efficiency is low, and the required manual work quantity is large. In addition, no matter the conventional horizontal surface plastering or the cambered surface plastering is carried out, the surface folding operation is usually required after the plastering process, and the conventional plastering machine does not have the surface folding function, so that the construction efficiency cannot be further improved.

In addition, in recent years, with the continuous development of tunnel construction technology in China, in order to effectively improve the stability and durability of an inverted arch structure, new knowledge is provided for requirements of inverted arch construction. The template for inverted arch construction is optimized from a simple single small template to an integral type low-side wall inverted arch template driven by a trestle, and then is further optimized to a full inverted arch template of a full inverted arch section template. The tunnel inverted arch layer is constructed with full-width inverted arch template, and template cost increases to some extent, and inverted arch construction space is also compressed further, and when pouring construction, the inverted arch layer can't be vibrated comprehensively in the below of template.
