Cast iron manhole covers have many designs, one of them is a recessed manhole cover. This manhole cover has a different cover design from the manhole covers in general. Generally, manhole covers have a flat design on the outside and hollow on the inside. While the recessed manhole covers have a hollow design on the outside and flat on the inside.
Specification
1. Unique Cover Design
The recessed cast iron manhole cover has a unique cover design. The outside has a space that we can fill with concrete to put ceramics, stones, paving, and other materials. So that you can adjust the material with the material used in the area where the manhole cover is installed.
2. Equipped with keyhole
To open the manhole cover you need the hook sticks which you will enter into the keyhole. Then you can easily lift the manhole cover using the hook sticks.
3. Design without hinges
A recessed manhole cover is usually designed without hinges. This is because the recessed manhole cover that is fitted with ceramic or stone makes it heavier. If using a hinge, will most likely be broken due to heavy loads.
4. Location of use
Recessed manhole covers are usually used in the pedestrian zone, building yards, and other open areas. By using recessed manhole covers people will not realize that there is a manhole cover in there.
How to Install Recessed Manhole Covers
1. Create a concrete foundation and install the frame
Like installing manhole covers in general, the first thing to do is make a foundation for the frame part. You can make the foundation from concrete material (a mixture of cement, sand, and water). After the foundation is ready, you can put the frame part on the foundation.
2. Install the cover on the frame
If the frame has been installed perfectly, you can put the cover part on the frame.
3. Concrete coating on the cover part
The cover part that you have installed properly on the frame, you can then coat it with concrete material. Fill the space on the cover part with concrete material.
You should not fill the space until full. Leave a space to put the tile or paving.
4. Install the tile or paving
The last one installs the tile or paving on the cover of the recessed manhole cover. You should install the tile flat on the surrounding surface. Because the flat installation of the manhole cover can prevent the pedestrian from tripping over the manhole cover.
