Water transfer and storage pipe project of Nishan reservoir
2024-06-27

Nishan Reservoir water transfer project mainly uses the Sihe main stream reservoir and sluice dam to replenish water for Nishan Reservoir and regulate the ecological environment. Nishan Reservoir is a comprehensive use of flood control, irrigation and aquaculture. Due to dry weather, upstream interception and other reasons, its ability to regulate water storage is gradually weakened. The implementation of the project can effectively control the water volume of the downstream river, restore the water surface of the reservoir, form a water system landscape from the Sihe River to the reservoir area, optimize and adjust the ecological environment, provide a good environment for the Nishan World Cultural Forum, and have great significance for the adjustment of the ecological region of the tourist city.

The main construction contents of this project include 2 new pumping stations, 23.494km water pipeline, 3 rubber DAMS of Xiaoyi River and management facilities. In order to meet the Nishan Forum, the project department requires that the whole line be completed on June 20, and the time is tight and the task is heavy.

As one of the major pipeline brands in China, Donghong Pipe Industry Co.,ltd.contracted the pipeline project of this project, showing its comprehensive capabilities in technology, design, engineering, products and other aspects. The project used PCCP pipe and steel pipe (steel pipe calibers DN1620,DN1820, and PCCP pipe calibers DN2200 and DN2000). All pipes are buried, and the main processes are trench earthwork excavation, pipeline foundation treatment, pipeline installation, trench earthwork backfilling and so on.


This project is the use of Donghong coated composite steel pipe, composite steel pipe is a key project that Donghong Pipe industry invested heavily in 2019. The two major workshops of the entire west factory produce composite steel pipe, the industry's advanced steel pipe production equipment and first-class technology, so that Donghong can operate freely in various calibers and processes of composite steel pipe, and the quality is outstanding. It has been praised and recognized by many market engineers.
