With the development of the times The size of urban sewage outlets is different. For example, for some roads with smaller standards, their sewage outlets will be smaller, while the sewage outlets on some large sections of roads will be wider. When installing stainless steel manhole covers, it is necessary to measure the size of the drain outlet pipe in advance, and then purchase stainless steel manhole covers of different sizes according to the practical size, so as to ensure the smooth installation. Assuming that the size of the selected stainless steel well cover is different from that of the drain pipe, the device will not be able to continue.

Before installation, the construction personnel should ensure that the height between the plane of the stainless steel manhole cover and the surrounding ground should not be more than 3cm, otherwise the time of installation will lead to the imbalance between the manhole cover and the ground. Once unbalanced, this section of road will stand out significantly, thus increasing the possibility of being stolen. Theft is the second. Because the manhole cover is relatively high, it will also make it inconvenient for pedestrians or vehicles to walk on the road.

In order to prevent the stainless steel manhole cover from moving due to various reasons, the construction personnel need to use some concrete to press the edge of the stainless steel manhole cover at the end of the device. After the stainless steel manhole cover is fixed, the stainless steel manhole cover is not easy to move, resulting in some unnecessary trouble. At the same time, when installing the stainless steel manhole cover, the construction personnel must keep the front of the manhole cover upward, which is the correct installation step.
