Based on material, manhole molds are classified as either plastic or steel. Plastic molds are lower in cost and lighter, but relatively weaker in strength and durability. Steel molds are stronger, have a longer service life, and can withstand greater pressure, but are more expensive.
Based on shape, manhole molds include round and square molds. Round molds are more widely used, distributing stress evenly and ensuring smooth drainage. Square molds are used in specific situations, such as in areas with regular shapes, facilitating integration with surrounding square structures.
Based on size specifications, manhole molds come in various models with different diameters and heights. Smaller sizes are suitable for small drainage systems or specific localized areas, while larger sizes are used in large-scale municipal drainage projects.
Different types of manhole molds have their own characteristics and applicable scenarios. Selection is based on a comprehensive consideration of specific project requirements, budget, and other factors to ensure the provision of suitable molds for the project, guaranteeing the construction quality and functional performance of the manhole.
