Well covers play an important role in our life! Nowadays, a new type of nodular cast iron well cover has been widely used. The following edition takes Shandong Ductile Iron Well Cover as an example to introduce the design specifications and performance standards of this kind of Well Cover. I hope you like it!
1: The well cover should be sound-proof, which requires the contact and occlusion surface between the well cover and the wellbore to act directly on the T-shaped rubber strip, in order to be flexible and rigid, and to eliminate noise。
2: Of course, anti-skid is also needed. The 3 mm raised pattern on the surface of the well cover is used to prevent skid and avoid accidents.
3: The seismic protection of well cap is to set U-shaped groove at the stop of well circle, and insert T-shaped synthetic rubber strip into U-shaped groove to play a cushioning role and reduce vibration force in the contact process between well cap and well circle.
4: Well cap must have a certain bearing capacity, not easy to damage. How many accidents will happen if the pressure is deformed.
5: There is also need to prevent displacement. Four riveting bolt holes are reserved in the well circle to distribute evenly at 90 degrees. Four ground bolts are used in each set to avoid displacement caused by mechanical rolling during road construction and play a certain anti-theft role.
6: Ductile iron double-deck covers are often stolen, resulting in many safety accidents, so theft-proof has become one of the standards of covers.
