The disposal of waste water has always caused a serious headache for mankind. Despite, that channeling was already known to ancient civilizations, the systems they created were still very rudimentary.
The development was followed by a major decline in the Middle Ages, when urban citizens did not care at all about observing basic hygiene requirements. You put the contents of the nightstands into the castle moat, or worse, poured onto the pavement. Thanks to this, sweepers were common throughout the continent, devastating epidemics. Even if they were smaller, local measures, these did not produce the expected results.
The need for the construction of a modern sewer network is due to the relationship between pathogens that settle in sewage and regular epidemics. relationship brought to life by his mapping. A 19. century became more and more clear, that draining sewage does not only eliminate the stench, but it can also significantly improve public health conditions. In addition, the crowds pouring into the cities due to the Industrial Revolution made solving the problem even more urgent. Although the 20. In the 19th century, canal networks began to be built around the world, there are still areas, which are waiting to be connected.
Today's channels, just like their millennia-old predecessors, they take the effect of gravity as a basis. The waste water is transported from the living environment through pipes that ensure the appropriate slope. As a result, one of the most important pillars of planning is the determination of the ideal slope angle.
In this post, we will briefly explain its significance, and we present those damages as well, which can be caused by not well defined values.
What rules apply to the slope angle?
There are predetermined rules for the formation of the slope angle, which are contained in the List of Hungarian National Standards. The regulations 3 and 5 a slope angle of between 1000 and 1000, so one 10 for a meter-long section, no 3-5 cm means a difference. In this list, professionals can get a precise description of the recommended material of the pipes, and also about the size of the diameter.
Why is it important to accurately set the slope angle??
An improperly specified slope angle results in the formation of blockages. If the angle is too large, the water simply rushes through the channel, but it does not carry the impurities with it. These accumulate later and cause significant blockages in the system.
A small slope angle produces similar problems, since without an ideal speed, the water is unable to transport the various materials. The incorrect slope angle therefore definitely causes a blockage in the channel.
How to eliminate the blockage?
Only the already formed blockage specialist can effectively remove it. The best tool for this is sewer cleaner with woma machine, whatever 300 with bar pressure, it flushes the dirt out of the pipes. In addition to cleaning blockage technical tools are also required to explore its location. The most commonly used method is camera detection.
In addition to the slope angle, what pitfalls can arise during construction?
In addition to setting the slope angle, the channel many factors must be taken into account during its implementation. The most important of these:
-
Instead of right-angled elbows, the blockage From the point of view of prevention, soft arches are more useful. A 90 sediments that cause clogging are more likely to accumulate in steep parts.
-
The rubber rings responsible for the fit must be placed precisely, as protruding parts here and there can catch dirt.
-
The quality of the soil surrounding the canal must be taken care of. The soft, the system can sink quickly in sandy soil.
-
Vegetation inspection is also very important. When installing, the trees around the canal must be measured, and the location of bushes, as the growing root system can cause serious damage to the pipes.
