Helping options for underground structures from grained

Microbial corrosion, or microbiologically determined corrosion (IOC), is "gradual damage to metal or reinforced concrete caused by the metabolic activity of microorganisms." This corrosion damage caused billions of rubles of damage to our water supply systems, especially our storm and sewer systems, although the IOC can occur everywhere where metal and water are found. The search for solutions to eliminate corrosion damage depends on where it happens, why it occurs and how destructive or expensive will be repaired or replaced.

There are several different types of bacteria responsible for the IOC in metals common in soil and water; All of them are classified as aerobic (require oxygen) or anaerobic (oxygen is not required). Sulfatered bacteria (SFB) are anaerobic and are responsible for most of the corrosion caused by "Steel" in sea water; While the oxidizing iron and manganese bacteria are aerobic and most often responsible for fast corrosion and point corrosion in the weld seams of pipelines (even for stainless steel). Microbial corrosion can also occur in plastics, concrete and many other materials.

In the strengthening and sealing projects of engineering tunnels, specialized engineers often deal with a large problem of water infiltration, which causes corrosion damage.And, as a result, the flow of water is constantly increasing in the tunnels.

There are several ways to combat corrosion, including:

- regular mechanical cleaning;

- the use of corrosion inhibitors to combat the growth of bacteria;

- Full drainage and ensuring a dry medium.

What can help Граундтек:

Since the replacement of the tunnel is not an economical option for any operation service, then dehydration of the tunnel (so that it can dry by increasing his service life) is just a solution that is Граундтек teeth.

Plan of stopping water intake in Tunnel:

This plan provides for the introduction of geopolymers into the target zone to fill the voids in the ground around the tunnel, mainly blocking ways of water intake into the tunnel. The discharge points are located through the specified intervals and at a given depth according to the developed engineers of the Граундтек project. The process of depth injection Граундтек reduces the flow of incoming water into the tunnel completely either to the "drip" level, which allows the tunnel to dry, creating a less favorable medium for the IOC and creating conditions for long-term operation of the structure.

Good day!I understand correctly, it looks like waterproofing?Only if the pipeline is put into operation, and not during installation work?

Grained materials can perform waterproofing functions.This is not a classic waterproofing that comes to mind at the first mention.

Such pipes are regularly checked or from the inside, the launch of the probe along the entire length and collecting data, or outside (without stopping operation) with the help of ultrasound or electromagnetic equipment, depending on the pipe material

And what could be corrosion in polypropylene tubes?

Aleksandr Sinchenko (inzhener GROUNDTEK) Oct. 28, 2020

In polypropylene tubes (without the presence of metals) corrosion can not be, but such pipes are not universal and not everywhere

Here, an integrated approach is needed ... But taking into account that this is a municipal property, that is, "draw", then the situation is inert to change

Yes, such works are possible.But the main thing is to deal with the reasons and consequences of the disturbing problem.

If I understand correctly, your material envelops the pipeline, creating something like a cocoon!?

In general, yes.The behavior of the material resembles the pipeline enveloping and blocking the flow of moisture from

Evgenij Novitskij (inzhener GROUNDTEK) Dec. 28, 2020

There are various ways to detect it.Therefore, the arrangement of its location is quite sufficient for frowning and the focal examination of the state of the base and the pipeline as a whole

No, does not affect.The material after the hole is forms an inert polymer that does not interact even with the chemical composition of the environment, and what to talk about the biological component ...

And if there is an underground highway for collecting wastewater and on one site there is a regular drawdown ... stop this collector is impossible, and you need to solve the problem ... And what can you help?

Aleksandr Efimchik (inzhener GROUNDTEK) Dec. 28, 2021

It depends on what are the solutions requirements.The first thing is to inspect the collector and clarify its current state and position in space.Next, determine the place of leakage.After that, choose the method of tampony.All this can be done without opening and earthworks.You can even align without excavation.But this is only based on your common input data ...
