Manhole covers: The “Safety Shield”
High-quality manhole covers are made of materials selected according to the scene.Solve these problems precisely.
It is an essential safety component for underground pipe networks!
Choose the right one, achieve zero safety accidents and halve maintenance costs.
Save 30,000 to 80,000 yuan every year.
It can also be adapted to multiple scenarios such as municipal facilities, residential areas, and factories.
Durable and worry-free.
First. Four Major “Hardcore Advantages” of Manhole Covers
Full coverage of load-bearing grades: Eliminating the safety hazard of “breaking easily under pressure”.
Anti-theft and silent dual online: Residents’ lives are more reassuring.
Corrosion-resistant and rust-proof: Its service life is three times longer than that of ordinary cast iron manhole covers.
Super flexible adaptability: No need to modify the wellhead during installation.
Second, “Blind eye selection” for 5 scenarios, ensuring compatibility without any pitfalls
Municipal roads: Comply with municipal engineering standards.
For the courtyard of the residential area: Use lightweight stainless steel or composite material manhole covers.
Factory area: Select corrosion-resistant ductile iron manhole covers.
Ensure the safety of industrial pipeline networks.
Scenic area parks: Enhance the quality of scenic areas.
Underground pipe network: Select dedicated manhole covers with markings for distinction.
Anti-fall design to prevent pipeline maintenance accidents.
Three. Four “pitfall Avoidance Standards”, Choose the right One and don’t waste money
Select the material according to the scene: For vehicle lanes, choose ductile iron (with strong load-bearing capacity).
For sidewalks, choose composite materials (lightweight and aesthetically pleasing).
For damp scenarios, choose 304 stainless steel (corrosion-resistant).
Confirm the load-bearing grade: For sidewalks, select A15 grade (≤15 tons).
The lane selection for the residential area should be B125 grade (≤12.5 tons).
For municipal main roads, D400 grade (≤40 tons) should be selected.
Failure to meet the load-bearing standards can cause safety accidents.
Check the safety design: It must be equipped with anti-picking lock clips (to prevent theft) and anti-fall nets (to prevent falls).
Anti-slip patterns are added to the manhole covers on the carriageway (to prevent vehicles from skidding).
Check the dimensional accuracy: The diameter error of the manhole cover is ≤±2mm.
The thickness is matched according to the load-bearing grade (D400 grade ≥100mm).
Four. Three “Longevity Tips” to Last 3 to 5 years longer
Regular cleaning and inspection: Avoid squeezing the manhole cover after hardening.
It leads to deformation and loosening.
Timely tightening and maintenance: Minor looseness is not dealt with.
It will gradually expand and cause displacement.
Avoid illegal crushing: Use according to the load-bearing grade.
It can protect the manhole cover.
It can also prevent safety accidents.
It’s a win-win situation. Read More
