Sewer manholes are a topic of active discussion at all times. Definitely an important component of any communication system. A person is trying to build it in a private house. Not a single apartment building can do without it. But not everyone understands how to properly install the hatch. Before starting work, it is worth identifying some important features and answering a few simple questions.

What is a manhole for?

Everyone understands that if the length of the pipes is long, then sooner or later repairs and constant maintenance will be required. It is for this reason that one cannot do without the organization of technological wells. They can be used to access various areas of human activity. These are not only sewage pits, but also a gas pipeline, communications, etc. For convenience, they put a sewer cover on them, which must meet all the requirements.

It is in such recesses that locking nodes are created and thoseto distribute the load. Do not forget that the system should consist of control and monitoring mechanisms. In this case, sewer manholes must have a cover. And it is important in this matter that the protection be as reliable as possible, and no one could open it on purpose and by accident. Otherwise, animals and even people may get there.

In the process of installation, a heavy, reliable cover is made. And here it must be said that the main purpose of the cover is safety for everyone around. Why are manholes round? The answer to this question is simple. This is done so that the constituent elements can be applied to any similar structures in different regions. There are characteristics and features that each person should be aware of. Creating hatches is not easy. This process is time consuming and costly.

Types of hatches

If you draw a parallel, then not so long ago this design was made only of cast iron. Today everything has changed. But it is worth saying that only reliable materials are used for work. They must withstand severe loads, up to collisions with trucks. There must be no movement or cracking under the structure. The main sewer manholes made of cast iron can withstand a load of up to 25 tons. Today, when using other material, these conditions are taken into account without fail.

To prevent theft, they began to use polymeric materials and rubber for such work. In addition, you can find a sewer hatch made of plastic. But it must not be allowed to move.cars, so most often they are on the sidewalks. Such materials have their own advantages (for example, they can be painted in a wide variety of colors).

Use of polymers to create round manhole covers

This material is unique because it can withstand the load and last for many years. Such hatches are installed on the roadway, footpaths and even in green spaces. They are easy to make invisible, and it doesn’t matter where to place them - this feature suits many. As a result, these hatches appear on the plots of private houses.

The installation of this design is not difficult and is not laborious. Since there is no contact with metal, sparks are completely excluded. Their features also include chemical compounds added to the composition. They will not allow further processing, which means there is no point in kidnapping them. The price for such sewer manholes is low (up to a thousand rubles), which means that you do not need to overpay.

Are there markings?

For ordinary people, all hatches on the road are the same, although they are not. There is a special marking on the lid, with the help of which a certain understanding occurs. In the process of creating hatches, letters are placed on them:

• K - Sewerage.
• B - water supply.
• D - storm sewer.
• G - hydrant.
• TS - heating network.
• GS - gas pipeline.
• GTS - telephone network.

Specialists do not need such indicators, becauseas they have special schemes. They are created when laying any communication, so getting permission for any additional work is not so difficult. When manufactured from cast iron, products can be light and heavy. And the designations are performed, respectively, by the first letters of the words. At the same time, each sewer manhole cover has its own characteristics, it is carried out using a special technology.

What is the installation work?

If you need to install a well on the site of the house, then the choice of cover depends on the financial capabilities of the owners. Since there will not be a large load on it, then there is simply no need to make a thick one. The cost depends on the thickness. If it is a cast-iron structure, then it is easy to purchase for two thousand or a little more. The price of sewer manholes made of polymer materials is even cheaper.

There will be no great difficulty in installing the product. The manhole cover is simply placed on the created support rings. They are made of concrete to be reliable and durable. In addition, an important task is to prevent water from getting inside, which means that a slight elevation is made above the lawn. There is an important point: the construction should not be allowed to fall below the required level.

What you need to know about operation?

Polymeric materials and other components are simple in the device, but in the process of use it is worth knowing some features:

• Open the lid carefully, without sudden movements. In order not to harmyourself (since it is heavy), a special tourniquet made of durable metal is used.
• Gases are gathering inside. If the lid is open, they may ignite. Therefore, fire cannot be used.
• Cleanup is always done by teams. It is impossible for a person to plunge into a well alone.
• To carry out processes inside the well, a special ladder is needed. It must be the correct length.
• Manhole sewer plastic, cast iron or any other opens only during daylight hours and with a special fence.
• Descend into sewer wells after airing and in special clothes.

It is believed that round sewer manholes are easy to purchase, as this is the most common form that has been around for many years. They are created according to a single project, so they are the same even in different regions. The demand for such a protective structure is always relevant, because there are situations when they are stolen.

Conclusion

Certainly, creating special alloys for the hatch is profitable. But an important task (especially in urban areas) is load endurance. They have a long service life, but the time comes and they need to be replaced. Even owners of private houses should create maximum protection for their septic tank. Sewer hatches are in demand, and you need to choose them depending on the purpose, taking into account the characteristics and features.
