Cast iron manhole covers are also well known, but some safety production accidents are inevitable in the whole process of application of cast iron manhole covers. So how should people reduce the occurrence of safety accidents? I think this has something to do with the installation of cast iron manhole covers. Let’s have a look at this problem.

When installing cast iron manhole covers, people must first dig deep foundation pits. During the excavation of deep foundation pit, except for the ground structure within the reinforcement range of wellhead structure, the ground structure shall not be excited around the wellhead. The excavated raw materials shall be stacked on the ground protective layer, removed immediately, and then the shaft wall wellhead shall be built. The sewage inspection shall be covered by the wellhead. After inspecting the well wall, install the temporary cast iron well cover immediately for well cover maintenance to avoid engineering materials or dirt falling into the well and prevent safety production accidents.

The cast-in-place concrete is usually used when the well cover is poured with concrete. Before the concrete pouring, the raw materials for safety protection must be laid around the wellhead to prevent the concrete from polluting the ground and endangering the beauty of the ground. After the completion of construction, water covering and watering shall be selected for curing, and enclosure structure measures shall be taken to prevent it. Avoid damaging the reinforced concrete or loosening the cast iron manhole cover by human factors.

During the installation of well cover, the traffic shall be dredged. The surrounding of cast iron well cover shall be selected with pea stone concrete or submerged slope higher than the ground in advance to ensure driving safety.

The above are some key points to prevent safety accidents of cast iron manhole covers. We hope you will pay more attention during the whole installation process to avoid unnecessary safety accidents.
