Manhole Cover Installing Factors To Be Considered

Many factors should be considered when installing the manhole cover. For example, the problems that usually occur after a period of time are: the manhole cover sinks, the manhole cover moves, the manhole cover makes abnormal noises, the appearance of the manhole cover is missing, and the friction is too small to slide on it. In advance, after considering these factors, the resettlement time should be extra vigilant. For example, there are stripes and handwriting on the surface of the manhole cover. During construction, be careful not to damage the stripes and fonts. You can find a thin piece of iron or spray a layer of asphalt meter on the surface of the manhole cover, or cover the manhole cover with plastic film to prevent the cement from sticking to the manhole cover to benefit the environment and damage the fonts or friction patterns. The outer well ring of the manhole cover shall be constructed strictly according to the planned construction drawings, and the size shall not be altered at will to ensure that the manhole cover can be opened or closed freely. During the construction of manhole cover, especially cast iron manhole cover, due to the extremely heavy and heavy self comparison, the installation shall be carried out with some machines. The construction machine shall be careful not to encounter the appearance of the manhole cover to avoid damage to the appearance of the manhole cover.
