Excavation and Pipe Exposure

In most applications, it’s likely that you’ll need to excavate the site where you plan to install your domed manhole. Excavation can very a very delicate process, as you’ll need to make sure to clear enough room for installation.

Once your installation site has been fully excavated, you’ll need to expose the pipe to which your manhole will be attached. Generally, you should only expose only the amount of pipe necessary to complete the installation, as this will make finishing up easier. Excavating and exposing the pipe will likely be the two most time-consuming steps of your domed top manhole installation.

Once the installation site is ready, you need to make a pad for the manhole. First and foremost, you need to be certain that the pad is level, as installing your manhole on uneven ground can lead to big problems in the future. Also, you need to make sure the pad is large enough that it can accommodate the manhole, primary flow management device and any connectors. After the forming the pad, pour in the concrete and make sure that it is smooth and level.

Now that you’ve done all the prep work, you should be ready to get down to the actual installation. You’ll need to start by cutting and removing a section of your pipe. This is where you will install your manhole.

After removing the section of pipe, you can lower your domed top manhole into place. Be very careful with this step so that you don’t damage your manhole in any way. With your manhole in place on the pad, you can couple it with the flow pipe. Make sure that the connections are secure to avoid future problems.

After connecting your manhole and pipe, make sure that the manhole is level, and make any necessary adjustments if it is not. Lastly, fill in the installation site so that only the top of the manhole can be seen.
