It is one of the main factors that determine the quality of concrete construction. It is an important process that restricts the construction speed of concrete and directly affects the construction progress of the whole concrete project. At the same time, the template cost occupies a considerable proportion of the cost of concrete engineering, in large and medium-sized water conservancy and hydropower projects, the template costs usually account for
