AI Technical Summary
In existing technologies, the construction of variable cross-section vertical shaft lining requires the manufacture of multiple slipform devices of different sizes, resulting in high construction costs.
Design a variable cross-section vertical shaft slipform device including a central frame and an adjustable slipform frame. The central frame remains unchanged, while the size of the slipform frame is changed according to the diameter of the vertical shaft cross-section. Different cross-sections can be adapted through the detachable connection of the annular template and the annular truss.
This reduces the cost of manufacturing multiple central frames, lowers construction costs, and improves construction efficiency and flexibility.
