Concrete well rings - time proven technology
Historians claim that the first well, made of stones and other improvised materials, appeared in India. After four and a half thousand years, technology has become more advanced. Today, well concrete rings rule the ball, which we will tell you about below.
General information
Apply them to install drainage, inspection and sewer wells. They are made of cement grade not lower than 200 and fittings with a diameter of up to 1 cm.
Virtues
We note first of all their positive aspects:
- High strength and solid durability. Such constructions easily survive the effects of groundwater, high pressure, moisture and other harmful effects. Only cutting reinforced concrete with diamond circles can disrupt their structure. (See also the article Reinforced concrete wells: views.)
Interesting: the main competitor of such products - plastic rings have about the same strength (despite the low weight). However, they have a rather weak frost resistance, which does not allow them to outstrip their cement counterpart.
- Great combination of price - quality. This factor in the modern world is one of the most important.
- Ecological purity. This allows you to safely drink water from such a well.
- Ease of manufacture and installation. Such a structure can be made even with their own hands. It does not require platonic efforts.
- Comfortable operation. Due to the design features (the presence of special brackets), such rings are easy to clean.
Stamps
Now consider what may be the size of the well concrete rings. These indicators presented below are controlled by GOST 8020–90.
Marking | Dimensions (cm) | Mass (kg) | Volume of concrete (m3) |
KS - 7.3 | 70х35х8 | 130 | 0,05 |
KS - 7.9 | 70х90х8 | 380 | 0,15 |
KS - 10.3 | 100h30h8 | 200 | 0,08 |
KS - 10.6 | 100h60h8 | 330 | 0,16 |
KS - 10.9 | 100х90х8 | 600 | 0,24 |
KS - 15.6 | 150x60x8 | 670 | 0,265 |
KS - 15.9 | 150х90х8 | 1700 | 0,40 |
It should be clarified that the volume of concrete for well rings can vary depending on the brand of cement (slightly).
Independent production
If you are eager to create such a structure on your own, then the instructions below are especially for you. We will analyze this process in detail.
Preparation of the solution
First, we will tell you how to prepare a very durable solution. For best results, purchase a cement brand of at least 400.
Совет: специалисты рекомендуют использовать, так называемый «созревший» цемент, от даты производства которого прошло более 30 дней. Такое вещество обеспечит особую прочность.
For each part of the cement we take:
- Gravel (3-4 parts).
- Sand (2-2.5).
- Water (0.5-0.6).
Tooling preparation
To accomplish the task, you will need, firstly, a spacious construction site, and, secondly, certain equipment.
The list is as follows:
- Concrete mixer. If we are talking about large volumes, it is better to purchase a special device. If not, then a few shovels and a sheet of metal on which the solution will be mixed by hand will suffice.
- Forms for rings.
- Vibrator installation.
- Devices for lifting rings, because they have an impressive weight (even the smallest).
- Reinforced frame.
Recommendations for making the form
You can buy blanks of any size. However, if your budget is strictly limited, you can make them yourself.
To do this, you can use various materials at hand:
- Two barrels of suitable diameters (so that one was 8–12 cm larger than the other). They will need to be interconnected. Also in the course you can put old air ducts or pipes.
Tip: You can use plastic parts. If we are talking about a small well, then this option is even better, because PVC is lightweight and easy to work with.
- Если перечисленных «богатств» у вас не оказалось, можно изготовить цилиндрические изделия из стальных листов. Соединить их можно дверными навесами, которые закрепляются посредством сварки.
Do not forget to immediately install reinforcing rods in the space between the walls. They will give the design strength. You can also use ready-made reinforcing frame.
Main scope of work
Before you start pouring, you should remember all the requirements for this procedure:
- The temperature should be between 8 and 20 degrees.
- Humidity is not higher than 60%.
- For cement, direct exposure to sunlight is detrimental. Therefore, when working in the heat should cover the product with something.
If all requirements are met, you can proceed directly to the fill.
We do it in the following sequence:
- When the mixture is thoroughly mixed, it must be gradually added to the form. This should be done gradually, in layers of 15-20 cm. The bay of the first layer must be carefully sealed with a metal rod.
Note! Without such a procedure, the product will not be durable. You can use other tools - shovels, hoes, etc.
- This method is necessary to fill the workpiece in half. After that it is required to remove wooden struts. (See also the article Putty for concrete: how to do.)
- Next you need to fill in the form completely. After which you will need to level the entire solution. The surface should be perfectly smooth, because it will be docking. Remember this.
- To achieve maximum compaction, a construction vibrator is used. It allows you to fill all the voids, giving the structure a special strength. If necessary, add a solution.
- Now you need to close the workpiece to ensure tightness and protect it from ultraviolet radiation.
- After waiting for three or four days, you can disassemble the form. However, if the humidity and temperature indicators are in perfect condition, then this can be done much faster.
- This billet cannot be moved, because the mixture has not yet gained proper resistance. It is necessary to water it with water for 6–7 days. After this period, it will be ready for transport and installation.
- Diamond drilling holes in the concrete will lead to the wells of the pipe. This technology makes it possible to make a hole of any thickness very quickly and without the risk of cracking.
Conclusion
This is the time to finish our story, but if you have any questions, then there is absolutely no cause for concern. In the presented video in this article you will find additional information on this topic, which will provide answers to them.
