How to determine the size of the brickwork of the ductile iron manhole cover? The following is just like everyone's introduction, I hope it will be helpful to everyone. The main application areas of ductile iron manhole covers are municipal roads, highways, communications, electricity, tap water, communities, schools and other parks.
The brick masonry construction of ductile iron manhole cover should be based on the manhole cover size designed by the design institute to determine its inner diameter or length * width, radius (if it is constructed according to the actual sample), it can also be implemented according to the corresponding standard. When laying the well, it must be noted that the inner diameter of the wellhead should be consistent with the inner diameter of the manhole cover and grate, and the installed manhole cover should be level with the road surface. After the concrete or asphalt is cast and laid, the cover should be opened and cleaned in time to avoid mortar or asphalt pouring the inspection well cover and the seat into a body, so as not to affect the opening in the future.
In order to ensure the normal use of ductile iron manhole covers, attention should be paid to the installation quality, so that the dimensions are accurate, the installation is firm, easy to open, and the appearance is clean and beautiful.
Points of ductile iron manhole cover:
1. Beautiful appearance: simple lines. Silver appearance, modern trend.
2. Good drainage: The leaking area is 83.3%, which is more than twice that of cast iron.
3. Anti-theft design: The lid and the frame are connected by a hinge, which is anti-theft, safe and easy to open.
4. Saving investment: a large span. Under heavy load, the price is lower than cast iron and saves the cost of crushing and replacing if stolen.
5. High strength: The strength and toughness are much higher than cast iron, which can be used in large-span and heavy-load environments such as docks and airports.
6. Multiple specifications: meet different environments and loads. Span, size and shape required
7. Good anti-theft:
This product uses steel fiber composite materials. It is molded at high temperature and has no secondary use value, so it is natural anti-theft.
8. Convenient and beautiful:
The weight of the same specification products is only one-third of the cast iron cover plate, which brings great convenience to installation, inspection and maintenance, and produces products of various specifications and colors according to customer requirements, even for management, and beautify the city.
9, long life:
Not afraid of acid and alkali corrosion, no rust, electric fringe, abrasion and weather resistance.
10, high precision
There are many applications of ductile iron manhole covers: water supply, drainage, sewage, etc. for municipalities, gardens, parking lots, highways, docks, power plants, steel mills, airports, residential landscape roads, urban sidewalks, motorways, squares, lawns and flower ponds, etc. Communications, electricity, natural gas and other projects. Different from other manhole covers, ductile iron manhole covers are basically more beautiful and more beautiful in application, so the name of ductile iron landscape manhole covers is actually well deserved.
The above is the determination of the size of the ductile iron manhole cover, and the points of the ductile iron manhole cover, and what are the functions of the ductile iron manhole cover. Municipal administration, gardens, parking lots, highways, wharves, power plants, steel plants, airports, and residential landscape roads. Welcome everyone to come. Purchase.
