Background
In the construction process of a vertical shaft tubular pump structure, the construction process usually involves a complicated flow passage structure, and the flow passage structure is in a specially-shaped curved surface shape. This results in a complicated concrete construction procedure for the runner.
Conventional formwork support structures do not meet the requirements of such construction. Therefore, the construction can be carried out smoothly only by adopting the special template.
For the runner with a large size, a steel template is usually adopted, but for the runner with the relatively small size, if the steel template is adopted, the construction difficulty is large, and the cost is high, so that the design of the special template with low cost is particularly important.
When the vertical shaft infusion pump is involved, because the water flow in the outlet flow channel of the vertical shaft infusion pump is relatively quick, the inner wall of the flow channel can be seriously washed, so that the concrete on the inner wall of the flow channel needs to be smooth, and the requirement on the flatness of a template is relatively high. The outlet flow channel curved surface section has larger flow channel flow design, so the outlet flow channel curved surface section has larger body size, the template is easy to deform, and the flatness is integrally poorer due to more template splicing seams. The outlet runner concrete is constructed on a key line, so that the construction period of the outlet runner is of great importance to the construction progress of the pump station.
Therefore, in order to ensure the smooth construction of the outlet flow passage of the vertical shaft through-flow pump, the design of a template is required according to the shape of the outlet of the vertical shaft through-flow pump.
