The operating principle of this multi-stage telescopic steel dam:
This multi-stage telescopic steel dam carries out water-filling by inlet pipeline, is sluiced by drain water circuit, controls the lifting of dam body.If control dam body height, the pressurization size of by-pass valve control and pump is only needed to realize.
The invention has the beneficial effects as follows:
This multi-stage expansion steel dam is positioned at below the water surface when not running, and flushes, do not have any impact to river course with riverbed; Control height of dam by filling and emptying during operation, effectively adapt to the change of Various Seasonal water level, automatically can realize dam body by using pump priming pressurization and rise step by step or decline, and water-filling pressurization plays a protective role to dam body; This dam has novel structure, is easy to operation, dependable performance, utilization flexibly, construction works amount is little, the feature that economizes on resources, owing to being all steel work, its stability and erosion resistibility will have superiority than traditional structure, and engineering has good technique effect and economic serviceability.
