Exploring the Benefits and Applications of Gully Grid Cast Iron
The location of a sewer manhole must be carefully considered to ensure that the drainage system is effective and easy to maintain.[14][15] According to design standards, the distance between two manholes is typically between 7 and 20 meters, depending on the specific characteristics of the project.[16][17] In cities, the distance is 20 meters per manhole,[18] while in industrial or commercial settings it is 10-15 meters per manhole.[19][20] The distance between manholes in homes or restaurants is typically 7-10 meters.
The durability aspect is crucial, as bollards are subject to constant impact and environmental challenges. With a protective sleeve, the lifespan of a bollard is significantly extended, which translates to lower long-term maintenance costs for municipalities. Easy to install and replace, these sleeves minimize the downtime of street features, ensuring that public spaces remain safe and functional.
