The Yellow River Irrigation Project of Wenbi Electric Irrigation Station in Hequ County is divided into primary and secondary pump stations and water tanks.
The project adopts C30 concrete pouring.
Due to the range of water level changes, the design requires the concrete to use a first grade, with a frost resistance grade of F200 and an impermeability grade of W4.
The maximum particle size of the aggregate is 2/3 of the minimum spacing between the steel bars, not exceeding 25mm.
This time, artificial crushed stone with a particle size of 10-20mm is used.
