[0002] The whole landscape gallery is a reinforced concrete structure, and there are small and dense reinforced concrete grilles on the top of the gallery, which is not convenient for the installation of the formwork and the pouring of concrete. The reinforced concrete grille has a small cross-section and cannot be vibrated with a vibrating rod. It can only be vibrated manually, which makes it difficult to ensure the construction quality. At the same time, the grille is easy to expand the mold and its size cannot be accurately controlled.
