Several matters needing attention before use of ductile iron manhole cover

Bo tou tianlong casting ductile iron manhole covers, when they began to use basic requirements must be clear, in the application, for its advantages than we don't say you can understand, if you can't understand it very good to use items, so its use for the application of relative efficiency decreases a lot, the following by bo tou tianlong casting ductile iron manhole covers about before use it need to be aware of some matters needing attention

Ductile iron manhole cover

1, the manhole covers before use, check the hole cover material, the best recommended ductile manhole cover material is high strength steel fiber reinforced concrete, composite materials etc. Nonmetal material, do not use grey cast iron and domestic concrete products.

2. The surface of nodular cast iron manhole cover should be consistent with the color of the road surface. The surface of the hole cover should have a raised anti-slip mode. The raised height should be between 3 and 8 mm. This not only prevents slipping, but also promotes drainage and reduces the surface area of the well cover.

3. The corresponding processing method shall be used to handle the contact surface between the well cover and the well. In order to ensure the stability and reliability of the contact between them, jumping phenomenon should not occur when the vehicle passes by. If it is a metal derrick, it should be designed with absorbate material, and the material has a reliable connection with the well cover.

4. Before the installation of the well cover, the identification of the well cover should be paid attention to. In the center of the well cover, special Chinese and symbols should be used to represent the type of well cover, such as rain means rain check well; The effluent refers to a sewage inspection well; Water means a water supply inspection well; Heating refers to the nodular cast iron manhole cover used in heating inspection.

If we can be in the use of nodular cast iron manhole covers, pay attention to the items used, so won't appear too much problems in daily application, after the source of the basic processing, better use.
