Sewer manholes at all times are a topic for active discussion. Definitely this is an important component of any communication system. A man is trying to build it in a private house. Not a single apartment building is complete without it. But how to install the hatch, not everyone understands. Before starting work, it is worth identifying some important features and answering some simple questions.
What is a sewer hatch for?
Everyone understands that if the length of the pipes is large, then sooner or later repairs and constant maintenance will be required. For this reason, the organization of technological wells cannot be dispensed with. On them you can get to different areas of human activity. This is not only sewage pits, but also a gas pipeline, communications, etc. For convenience, they put a sewer lid on them that must meet all the requirements.
It is in such recesses that the locking units and those which should distribute the load are created. Do not forget that the system should consist of management and control mechanisms. In this case, the sewer hatches must have a lid. And it is important in this matter that the protection is as reliable as possible, and no one can open it deliberately and accidentally. Otherwise, animals and even people may get there.
During installation, a heavy reliable cover is made. And here I must say that the main purpose of the cover is safety for everyone around. Why are manholes round? The answer to this question is simple. They do this so that it is possible to apply the constituent elements to any similar structures in different regions. There are characteristics and features that everyone should know about. Creating hatches is not so simple. This process is time consuming and expensive.
Types of hatches
If you draw a parallel, 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 the collision of trucks. Under the construction there should not be movement and cracking. The main cast iron manholes withstand loads of up to 25 tons. Today, when using other material, these conditions are taken into account without fail.
To prevent thefts, they began to use polymeric materials and rubber for such work. In addition, you can find a sewer manhole made of plastic. But it should not be allowed to move cars, so most often they are on the sidewalks. Such materials have their advantages (for example, they can be painted in a variety of colors).
The use of polymers to create round manhole covers
This material is unique because it can withstand the load and serve for many years. Such hatches are installed on the carriageway, pedestrian walkways and even in green spaces. They are easy to make invisible, it does not matter where to place it - this feature suits many. As a result, these hatches appear on sections of private houses.
Installation of such a design is not difficult and is not time-consuming. Since there is no contact with metal, sparks are completely eliminated. Their features also include chemical compounds added to the composition. They will not allow subsequent processing, which means there is no point in abducting them. For such manholes, the price is low (up to a thousand rubles), which means that you do not need to overpay.
Is there a marking?
For ordinary people, all the hatches on the road are the same, although this is not so. There is a special marking on the cover, with the help of which a certain understanding takes place. In the process of creating hatches, letters are placed on them:
- K - sewage.
- In - water supply.
- D - storm sewer.
- G is the hydrant.
- TS - heating system.
- GS - gas main.
- GTS - telephone network.
Specialists do not need such indicators, since they have special schemes. They are created when any communication is being laid, so obtaining permission for any additional work is not so difficult. When fabrication is from cast iron, the products can be light and heavy. And the designations are carried out, respectively, by the first letters of the words. At the same time, each cover of the sewer manhole has its own characteristics;
What are the installation work?
If you need to install a well on a site of a 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 thickness depends on the thickness. If it is a cast-iron construction, then it is easy to purchase for two thousand or a little more. The price of sewer hatches made of polymer materials is even cheaper.
There will be no great difficulty in installing the product. The cover of the sewer manhole simply fits onto 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 above the lawn is done. There is an important point: the design 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 using it is worth knowing some features:
- Open the lid carefully, without sudden movements. In order not to harm yourself (since it is heavy), a special harness made of durable metal is used.
- Gases are gathering inside. With the lid open, they can ignite. Therefore, you can not use fire.
- Cleaning is always carried out by teams. It is impossible for a man to plunge into a well alone.
- To carry out processes inside the well, you need a special ladder. It should be a suitable length.
- Sewer manhole plastic, cast-iron or any other opens only in the daytime and in the presence of a special fence.
- They go down to the sewer wells after airing and in special clothes.
It is believed that it is easy to purchase round manhole covers, as this is the most common form that has existed for many years. They are created according to a single project, therefore they are the same even in different regions. The demand for such a protective design is always relevant, because there are situations when they are stolen.
Conclusion
Of course, the creation of special alloys for the hatch is beneficial. But an important task (especially in the urban area) is to withstand the load. They have a long service life, but the time comes and they need to be replaced. Even owners of private homes should create maximum protection for their septic tank. Sewer manholes are in demand, and you need to choose them depending on the destination, taking into account the characteristics and features.
