Stainless steel manhole cover Installation -1
To ensure the normal use of stainless steel manhole covers, special attention should be paid to the installation quality during construction,that is, accurate size, stable installation, convenient opening, clean and beautiful appearance.According to the technical standards of stainless steel manhole covers, the following installation details are formulated:
1、Select the size for stainless steel manhole cover
The selection of the size of the stainless steel manhole cover should be determined according to the size of the manhole in the design drawing of the design institute. If there is any change, it should be customized according to the requirements of the consumer.
2、Install Stainless steel manhole Frame
When installing the stainless steel manhole frame, you should first smooth it with concrete or cement mortar on the brick masonry at the manhole head. Be careful to keep the frame square and solid, and the plane and the ground height of the surrounding pavement should be horizontal on the same level. The whole is stable and must not be loose. In addition, concrete or cement mortar should be tapped around the frame, and get tighten and solid with vibration, and there should be no suspension or gaps.
3、Put in the stainless steel manhole cover
When putting in the stainless steel manhole cover, the sundries in the stainless steel manhole frame should be cleaned first to avoid affecting the flatness and making it difficult to lift in the future. When paving the cover, first lay 30mm thick cement mortar as a cushion, and then lay stone materials.

a、A.Brick masonry of manhole cover
For the brick masonry of the manhole cover, the inner diameter or length × width should be determined according to the manhole cover size designed by the design institute (it is best to construct according to the actual mock-up), and it can also be implemented with reference to the standard. And cast a concrete protection ring with a width of 40 cm on the outer ring of the manhole cover (if it is a cement road, you can also cast a concrete protection ring with a width of 20 cm and strengthen it with steel bars). The maintenance period should be more than 10 days.
b、Manhole cover size
The size of the manhole cover should be more than 100mm larger than the size of the manhole head on site. Before the filling is paved into the manhole tray, diluted concrete must be poured. After the pavement is completed, the maintenance period must be more than 20 days before it can be opened to traffic.
c、Install manhole covers on asphalt pavement
When installing the manhole cover on the asphalt pavement, care must be taken to avoid direct rolling of the manholeframe by construction machinery. When the pavement is cast as a whole, a hole slightly larger than the manhole frame should be reserved on the road surface and placed the frame in after the asphalt is paved. The full concrete pavement should be installed after the second stone is paved, it ensures the installation quality of the manhole cover to prolong the service life.
d、Manhole Cover Appearance Protection
In order to keep the appearance of the manhole cover beautiful and the writing clear, the manhole cover should be covered with a thin iron sheet or wood board during asphalt pavement construction to prevent asphalt oil from being sprayed directly on the manhole cover. During the construction of cement pavement, the manhole cover should be covered with plastic film to prevent damage to the surface gloss and writing.
e、Open the manhole cover in time for cleaning
After the concrete is cast on the manhole frame or the asphalt is laid, the manhole cover should be opened and cleaned in time to avoid time-consuming and laborious cleaning in the future or to prevent the asphalt from pouring the cover and frame into one, so as not to affect the opening in the future.
