Well Urban Flood Control Rainwater Outlet Gully Grate And Frame Ductile Iron Overflow
Producte Introduction:
The cast iron convex manhole cover square overflow well is an important equipment used in municipal drainage systems, mainly used for overflow control in rainwater or sewage systems. It is made of sturdy and durable cast iron material, with a raised manhole cover to prevent water backflow and overflow. The structure is usually square and suitable for covering and protecting the overflow well opening.
This product is widely used in urban drainage systems, industrial parks, residential areas and other places where drainage facilities are required. Its main function is to quickly discharge excess rainwater or sewage, prevent water accumulation, and protect the equipment and system in the well.
Structure And Design:
1.Raised manhole cover
The surface of the manhole cover is slightly higher than the ground to prevent water from overflowing or backflowing, especially suitable for areas with heavy rain.
The raised design can also effectively prevent mud and debris from entering the overflow well, thereby protecting the drainage system.
2.Square design
The edges of the square manhole cover are easy to install and fix, ensuring a tight fit between the manhole cover and the manhole frame.
The square opening provides a larger drainage area, suitable for drainage scenarios with large flow rates.
3.Anti-slip and anti-theft function
The anti-slip pattern design on the surface increases the safety of driving and pedestrians.
Anti-theft locks or hinged connections effectively prevent the manhole cover from falling off or being stolen.
4.Vents/drain holes
Some convex manhole covers are designed with vents or small drain holes to help quickly discharge small amounts of accumulated water and maintain air circulation in the well.
Manufacturing Process
1.Material smelting
Use medium frequency electric furnace or cupola to melt high-quality pig iron and scrap steel, and add spheroidizing agent (magnesium or rare earth alloy) for spheroidizing treatment.
2.Casting
Use sand mold or resin sand mold casting process to cast the blank of round grate.
3.Surface treatment
Sand blasting or shot blasting to remove surface oxide scale, and then apply anti-corrosion coating (such as asphalt paint or epoxy resin).
4.Inspection and assembly
Strict inspection of the appearance, size and load-bearing capacity of the grate to ensure that the product meets the standards.
