Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a simple circular template device. Background Art

[0002] A simple circular formwork device usually refers to a simple formwork system used to construct circular structures in construction. This type of device is widely used in construction projects due to its simple structure, quick installation, and low cost. It is especially commonly used in situations where circular or circular-like structures need to be constructed. The design of a circular formwork device usually takes into account factors such as structural stability, ease of construction, and cost rationality.

[0003] With the acceleration of urbanization and the continuous development of infrastructure construction, water supply and drainage, sewage treatment engineering facilities can be seen everywhere and are closely related to people's lives. In order to facilitate the inspection and maintenance of water supply and drainage pipelines and control the water flow rate, various inspection wells, valve wells, etc. are set up along the water supply and drainage pipelines. The underground inspection wells need to be equipped with well covers on the ground, and the well covers are the key part of the water supply and drainage system. It not only plays the role of protection, bearing and drainage, but also has the characteristics of convenient maintenance and inspection. In the construction of water supply and drainage projects, the amount of concrete used in a single well cover is small, and most of the manholes on the cover are circular. It is difficult to make circular templates during on-site casting, and the manhole diameters of well covers of different specifications are different.

[0004] If multiple manhole covers are to be constructed simultaneously, multiple sets of standardized steel or wooden formworks need to be manufactured according to traditional techniques. However, since it takes a long time to manufacture standardized formworks, the construction progress is slow and the cost investment is high when using traditional standardized formworks.
