Installation process of Ductile iron manhole square covers

The installation process of sDuctile iron manhole square covers usually includes the following steps:

Preparations before installation: Check whether parameters such as the size, shape, and weight of the manhole cover meet the installation requirements, and prepare installation tools such as wrenches and screwdrivers.

Clean the wellhead: Before installing the manhole cover, it is necessary to clean up the debris and dirt in the wellhead to ensure that the manhole cover can be placed on the wellhead smoothly.

Install the manhole cover base: After cleaning the wellhead, install the base of the manhole cover first, place the base on the wellhead and fix it with bolts.

Place the manhole cover: Place the ductile iron manhole cover on the base and adjust the position of the manhole cover to ensure that it is aligned with the base.

Fix the manhole cover: After the manhole cover is placed, it needs to be fixed on the base with bolts. When fixing the manhole cover, pay attention to the tightening force of the bolts to ensure the stability of the manhole cover.

Install the sealing ring: The sealing ring of the manhole cover is a key component to ensure the sealing between the manhole cover and the road surface. When installing the sealing ring, it needs to be embedded in the frame of the manhole cover and ensure that it is closely attached to the cover surface of the manhole cover.

Adjust the position of the manhole cover: Finally, it is necessary to adjust the position of the manhole cover to ensure that it is placed in the correct position and meets the design requirements.

Test the manhole cover: Conduct tests after installation to ensure the load-bearing capacity and sealing performance of the manhole cover. Some heavy objects can be placed on the manhole cover to check whether the manhole cover can bear the weight, and test the sealing performance of the manhole cover with water.

Mark the position of the manhole cover: After installing the ductile iron manhole cover, the position needs to be marked on the manhole cover for future maintenance and management.

Please note that during the installation process, relevant technical standards and safety specifications should be strictly observed to ensure installation quality, and appropriate safety measures should be taken to prevent accidents. In addition, special attention should be paid to the levelness of the manhole cover and the firmness of fixation during installation, and construction machinery should be prevented from directly rolling on the manhole seat. When installing on asphalt pavement, a hole slightly larger than the manhole seat should be reserved on the pavement, and installation should be carried out after the asphalt is paved.
