Ring aeration tank integral formwork support process

Abstract

The invention discloses a ring-shaped aeration basin whole formwork technique which belongs to the technical field of building construction techniques and comprises following steps: pouring and tamping bottom board concrete, installing basin wall inside and outside templates, linking a supporting scaffold, pouring and tamping basin wall concrete, removing the templates, the invention adopts a mode that installment of the basin wall inside and outside templates and linkage of the supporting scaffold are carried out interactively, the basin wall inside and outside templates are firstly installed and fixed with typed wall screws, then, the inner and outer supporting scaffolds are linked, then, the templates are installed continuingly on the supporting scaffolds, each installing height is two meters, height mark (11 meters) can be reached after installing like that for 5 times, after the templates are wholly installed completely, layered screw-type pouring and tamping are adopted, and as pouring and tamping are carried out, the template verticality is corrected. The invention adopts layered framework, the scaffolds are fixed with the typed wall screws according to the characteristics of big height and small thickness of the aeration basin wall, and the invention also adopts the layered screw-type pouring and tamping, which effectively guarantees the safety and stability of whole construction.

Description

[0001] Invention name [0002] The invention relates to a building construction technology, in particular to an integral form-supporting process of an annular aeration tank, which can also be applied to the form-supporting of other ring-shaped buildings with large height and small thickness. Background technique [0003] The aeration tank of the sewage treatment plant is a ring-shaped tank body, its plane size is about 186.2×46.3m, the tank height is 11-15m, the buried depth is about 5m, the wall thickness of the circular shell section is 300mm, and the bottom plate thickness is 400-700mm. The prestressed concrete structure is adopted. Because the aeration tank has the characteristics of large height and small wall thickness, the engineering structure is relatively complex and the construction precision is high. If the original conventional formwork technology is used, it is difficult to guarantee the safety and stability. , Therefore, it is necessary to explore a new formwork...

The prestressed concrete structure is adopted. Because the aeration tank has the characteristics of large height and small wall thickness, the engineering structure is relatively complex and the construction precision is high. If the original conventional formwork technology is used, it is difficult to guarantee the safety and stability. , therefore, it is necessary to explore a new formwork technology suitable for the structural characteristics of the project
