Despite the active use of modern materials in construction, reinforced concrete well rings are still relevant. The device is a structure made of a metal frame and concrete. The height of the rings can vary from 10 to 90 cm, and the diameter from 70 to 200 cm. The dimensions of well concrete rings are selected depending on the type and characteristics of communications. In addition, the objectives of using the structure are taken into account.
Application of the design
Reinforced concrete rings are actively used in the creation of sewers, sewers and ordinary wells. They are also used for connecting electronic communications and gas pipelines.
According to GOST, cement M 200-500 should be used for the production of such structures. Products in this range are subject to mandatory labeling.
Advantages of reinforced concrete rings
Concrete structures, which are used for arranging various types of communications, have a number of advantages:
- reliability and strength;
- complete tightness of all connection areas;
- easy installation;
- democratic price.
Among other things, wells and communications built using such structures are truly durable. They have high maintainability.
Reinforcement of reinforced concrete rings
The production of different types of this design has its own nuances. Not all models are subject to mandatory reinforcement. However, products with a steel frame are more durable and pressure resistant.
Factory models of reinforced concrete rings are reinforced using a special pressing technology using vibration installations. The process gives the products a strong shrinkage. Thanks to vibrations, air microbubbles are removed from the mixture, which contribute to the destruction of the structure.
Note! The first numerical designation indicates the diameter, and the second indicates the height of the ring.
Also, reinforced concrete structures are supplemented with additional parts, such as covering the bottom. In such a situation, the plate is marked PP or PC (for a bottom that matches the diameter of the ring). Bottom plates are designated PD. Such designs make the system airtight. They are laid on top and bottom to protect the structure from groundwater. In drinking water wells, slabs are used to prevent soil and dirt from contaminating the water.
It is quite difficult to select concrete rings for a well, therefore, in order to avoid installation problems, such products are made with markings. It indicates the necessary values, such as diameter and height. In addition, the marking will allow you to find out how much a certain product will cost.
Dimensions of well structures
In addition to the rings themselves, other structures are used in communications of this type. For them, the size of reinforced concrete structures is selected individually, taking into account calculations of the system’s operation. These types include additional and auxiliary structures. They are used to complement the main structural systems.
Note! When installing rings, first install the part with the bottom. Such a device will make the system cleaner and safer. For dead-end branches of the well, slab floors are used. In addition, such designs reduce the load on the entire communications system.
To ensure that the well complies with established standards, the structure can be installed in accordance with certain rules. You should work in a certain order:
- Choosing the optimal location. Wells for water supply and drainage systems are not installed close to residential buildings. They are usually installed at a distance of 5 m from the house. There should be no groundwater in the place where the well will be installed. Otherwise, you will need to spend additional money on sealing the structure. Free access for equipment should be provided to the installation site.
- Digging a pit. For such a task it is easier to hire special equipment. The hole must be made so deep that 2 rings fit into it. It is quite difficult to dig it by hand. Sand and crushed stone should be poured into the bottom. This layer should be at least half a meter high.
- Installation of rings. To complete the lower tier, you will need to lay a bottom slab. The elements are installed using a truck crane. The joint is reinforced with metal staples.
When the rings are installed, communications must be connected to the well. In addition, all connections should be made and the structure should be covered with a top plate. Then sewer hatches are installed.
Making reinforced concrete rings with your own hands
If the communications system requires a non-standard shape or size of the product, you can make it yourself. To produce reinforced concrete rings, you need cement, sand, reinforcing bars and a mold of the required size.
The mold is removed from the finished ring after 2-3 days have passed. The ring should then completely harden and dry. This will take a week.
Important! Finished products need to be wetted periodically. This will prevent them from drying out in the sun and cracking.
conclusions
As you can see, concrete rings have certain advantages and are not without disadvantages. They are quite durable, but they are heavy. When choosing rings for a well, you need to familiarize yourself with the markings and types of such products. This will help you choose the best product option for your needs. It is important to take into account many subtleties of selection and installation. Calculations will help you choose such products at a price.
