Formwork erecting construction method for underground cylinder structure
The invention discloses a formwork erecting construction method for an underground barrel structure. The formwork erecting construction method comprises the following steps that a soil body at a first preset depth is excavated out of the bottom of a foundation pit to form a center island and a foundation trench; a soil body with a second preset depth is dug out at the position of the foundation trench to form a sand padding groove, and construction operation is conducted in the sand padding groove; and a single-side formwork is installed at the position of the sand padding groove, and a supporting component is assembled between the single-side formwork and the center island, so that formwork erecting operation is completed. According to the formwork erecting construction method for the underground barrel structure, a reserved center island and a backrest used as a single-side formwork support are utilized, and a supporting component is directly jacked between the center island and the single-side formwork, so that the single-side formwork is reinforced more firmly, the labor cost and measure materials for fully building scaffolds in the middle are reduced, the dismantling and transporting cost after construction is completed is also reduced, and the construction efficiency is improved. And during concrete pouring, the pouring sequence does not need to be noticed specially, and the center island can be matched with the supporting component to provide enough supporting force to ensure that the single-side formwork does not deform.
一种用于地下筒体结构的支模施工方法，包括如下步骤：将所述基坑底部挖除第一预设深度的土体以形成中心岛及基槽；在基槽位置位置处挖除第二预设深度的土体形成垫砂槽，并在垫砂槽内进行施工作业；在所述垫砂槽位置处进行单侧模板安装，并在单侧模板与所述中心岛之间装配支撑构件，以完成支模作业。该用于地下筒体结构的支模施工方法，预留的中心岛，作为单侧模板支撑的后靠，利用支撑构件直接顶中心岛与单侧模板之间，使得单侧模板加固更加牢靠，减少了中间满搭脚手架的人工成本及措施材料，也减少了施工完成的拆除、倒运成本，而且混凝土浇筑时，可以不用特别注意浇筑顺序，中心岛可以配合支撑构件提供足够支撑力确保单侧模板不变形。
