What are and where used concrete wells

When carrying out construction work, it is very important to pay due attention to all details, for example, the installation of sanitary equipment. Currently, developers are trying to offer customers as much as possible materials that make its operation more reliable, simple and easy. And about what advantages have round and rectangular reinforced concrete wells, as well as other similar structures, consider below.

Why reinforced concrete

Преимущества ЖБИ

Products are manufactured for use in outdoor sewer systems. They can be installed in a common sewer network, as well as in the construction or repair of residential and industrial buildings.

Previously, the most popular materials for them were concrete and brick. However, this method because of its complexity was not effective enough. At present, for such purposes, industrial enterprises have established serial production of concrete products.

This material is quite profitable, with its use, builders can use various combinations and sizes of reinforced concrete wells, with the result that the whole well can be put together like a regular designer.

At the same time it can be performed with any parameters, which is also very important. The cost of construction depends on many factors, including how much concrete was used for reinforced concrete sewer wells.

However, the advantages do not end there, let's look at some more:

• similar constructions can be used in all types of soil;
• reinforced concrete sewer well is mounted quickly enough, and its service life and reliability are very high;
• can be used for key wells. Due to inertness, the material will not have any impact on water quality;
• care is minimal during operation - it is only necessary to clean the walls occasionally. Manually this is done quite simply, however, you can use the services of vacuum trucks, which will speed up and facilitate the process.

Areas of use

The scope of use of such products is wide enough - from heat and water to communication systems. At the same time, reinforced concrete products can be used for work with other underground utilities, for example, in places through which transportation of domestic sewage is carried out. Neither the aggressive soil environment, nor other factors have any influence on the reliability of operation of such wells.

Tip: if you plan to use in a harsh climate (for example, in permafrost conditions), it is better to apply a layer of waterproofing on them.

It is convenient to apply the design to obtain groundwater. For such purposes, the most frequently used mine options that can provide its flow from a depth of about 20 m. Less commonly used are wells of the key type.

According to experts, concrete has such mechanical characteristics that allow the use of products from it at any depth. At the same time, this design includes two main components: underground (trunk) and aboveground (mine with a tip). The diameter of such structures can also be chosen any, but the most often used w / w rings, with a diameter in the range of 800-1500 mm, the narrower the price.

The main components of the well

Let's try to deal with those components that need to be put together to get a sanitary well.

So, we will need:

1. Road plate, the main purpose of which is to cover the device on top.
2. Rings. Their number depends on how deep the well is.
3. Neck. It will be needed only for large-sized equipment.
4. Cover plate with pipes.
5. Wall ring used to select the desired depth.
6. Plate, which will be used at the bottom.

Tip: if you need to make a passage in a reinforced concrete well for pipes or cables, you can use diamond drilling holes in the concrete with professional crowns.

According to GOST 8020-90 there are two main sizes of reinforced concrete rings, which will be quite enough for use in the country house, these are:

• 1000 mm rings, weighing 700 kg and labeled KS;
• 1500 mm rings, weighing 1 ton and marked KS.

The height of each of these parts is also standard, and is equal to 890 mm. At the same time, such parts can be used not only for the construction of the dacha well, but also when creating water and sewer systems. The volume of reinforced concrete wells depends on how many rings will be used.

Tip: if in the process of making concrete to use infrared drying, it will significantly improve the quality indicators of the material.

Manufacture Categories

In the process of manufacturing such concrete products, the standards prescribed in the two State Standards - 13015-2003 and 8020-90 are used. It is necessary to use a fine-grained type of concrete, which has a low throughput of liquids. If it is necessary to increase the strength properties of the material, reinforcing materials (rods or wire) are used, which distribute the load. (See also the article Heater for concrete: features.)

Depending on the requirements for operating conditions, there are two main types of reinforced concrete elements:

1. For non-aggressive or slightly aggressive soils, concretes with normal permeability are used. Such products belong to the group A11 of SNiP 2.05.03-84.
2. For soils with an aggressive chemical composition, concretes having a particularly low permeability are used, which belong to the NK-80 group from a similar source. In addition, the products of this concrete can be used in the arrangement of cesspools, septic tanks and sewers.

Advice: when removing concrete goods, cutting of reinforced concrete with diamond circles has recommended itself well.

Recommendations for the installation of reinforced concrete wells

Most often in the conditions of our climate are used prefabricated devices.

The instructions below are presented in the form of a phased installation:

1. The first step is to determine the place that will be most suitable for installation..
2. Then it is necessary to dig a hole that will later become a well shaft.. It is worth noting that the larger the planned depth of the mine, the more laborious the process will be. However, it will simplify and accelerate the process of drilling using modern technology.
3. After the end of the previous stage, it will be necessary to pump out all the water that will flow into the pit..
4. Then it is necessary to pour and tamp the filter layer..
5. Crowned stage installation of the first ring. It is necessary to treat this very carefully, because it will depend on the vertical structure.
6. Most often, reinforced concrete rings for a well are installed using special equipment, less often with their own hands.. In the installation process, you must not forget to use for their fastening metal brackets, which are also used in the construction of the ladder, which can be lowered through the mine.

1. Each joint between the rings must be carefully sealed., and all the free space outside the mine is filled and compacted either with extracted soil or imported.
2. When installing the tip, it should be surrounded with a layer of clay.
3. The final stages of installation is to install ventilation and cover the shaft with a lid..

If you want the well to serve you reliably and for a long time, you must install it in accordance with all requirements. Such products made of reinforced concrete as a result of high strength properties, quality and ease of installation can be an excellent protection for pipelines.

Conclusion

We often find similar precast concrete wells in our courtyards, and think about their usefulness only in critical situations. Thanks to the various options for such w / w products, our life becomes simpler and more comfortable. The video in this article will help you find additional information on this topic.
