Advantage：Our anti-settling manhole covers have below virtue：The anti-settling manhole cover is a new type of multifunctional manhole cover, also known as “six anti-manhole covers”. The material is made of ductile iron 500-7, and the novelizing standard reaches level 3 or above. It is strictly in accordance with the national standard. At present, it is vigorously promoting production all over the country. The so-called six defenses are anti-falling, anti-noise, anti-deformation, anti-slip, anti-jumping, and anti-theft.

1. Anti-falling: A ductile iron net is designed for the well base to ensure the safety of citizens and children.

2. Anti-noise: A sealing rubber strip is designed between the well cover and the well seat, and a soft contact is formed between the cover and the seat, thereby eliminating noise.

3. Anti-deformation: The well base is designed with a 100mm surrounding structural pressure-bearing edge and a 190mm well-bore, so that the impact stress of the vehicle can be effectively diffused in multiple directions, greatly reducing the probability of settlement. , It is not easy to deform when driving and under heavy vehicles, and effectively solves the phenomenon of unevenness of the old manhole cover.

4. Anti-slip: The surface of the manhole cover has a dense pattern with convex and concave, and the height of the pattern reaches 3-8mm required by the national standard, which improves the coefficient of friction.

5. Anti-jumping: There are three buckles on the back of the manhole cover to fasten the locking device, and the well shaft corresponds to three buckle points. After the well cover is closed, the buckle point of the well-bore locks the buckle of the manhole cover, and the heavy-duty vehicle passes through to avoid bouncing.

6. Anti-theft: The well cover and the well seat are connected by 8.8-grade pin shaft screws. After installation, they are hidden underground. It is difficult to disassemble and not easy to steal.

Application：According to the bearing capacity of the product, anti-settling manhole covers can be used in the following places: municipal roads, highways, communications, electricity, tap water, residential areas, schools and other parks.

Remark：The company has complete and advanced production equipment and production technology, and can customize products of any size according to customers’ samples or drawings.
