Concrete, as building material, has been used for a long time. Firstly, it costs cheaper, secondly, it will last longer, and thirdly, construction is much faster. They are filled with the foundation of the future home. Walls are erected from concrete blocks, and strong underground communications, treatment facilities, the so -called septic tanks, and even cesspools are built from concrete rings.
However, most often concrete rings are used to build a sewage system. And use rings of different types. Each species differs from each other not only in size, but also by the method of connection.
Concrete rings with a lock.
Concrete rings with a lock are also called Euro rings. On the upper part there is a special ledge. And from below – exactly the same recess. Thus, the rings are tightly inserted into each other, while no additional mounts are needed. This peculiar castle is called the Falts.
Concrete rings without a lock
However, not all concrete rings are produced with a fold. Some of them are connected by the old fashioned way, with special brackets. But in this case, cracks may appear. To avoid this, the entire structure is poured with concrete. Когда раствор окончательно затвердеет, кольца при помощи крана опускают в котлован, места соединения изолируют и укрепляют, после чего яму зарывают.
Marking of concrete rings
The most common are KS-10, KS-15 and KS-20. This marking means the following: the letters of the CS are a sewer ring, and the numbers show how many decimeters are the diameter of the ring. Therefore, the marking of the KS-10, which means that we are in front of us-a concrete sewer ring with a diameter of one hundred centimeters.
The usual height of reinforced concrete rings is 90 cm. But there are other rings called premature. Their marking looks somewhat different. For example, KS-7-5. This means that it is 70 cm, and the height is 50 cm. They are used by additional rings in cases where the heights of the standard ring are not enough, and, if you add one more, it will greatly perform.
The manufacture of reinforced concrete rings is material only of the best quality. For a frame made of reinforcement, rods with a diameter of 0.6-1cm are used. The rods are bent into the ring and poured with concrete. The weight of one such ring can reach six hundred kilograms.
Thus, concrete rings can be safely called the ideal material for the construction of a strong and convenient sewage system.
