Wie verhindert man Erosion und Rohrleitungen entlang der Basis einer Stützmauer?

To keep a retaining wall safe, we need to do a few key things based on what I've learned on the job. First, we check the construction site to understand what kind of soil we're dealing with and how high the groundwater is. Then, we make sure to have good drainage systems in place so water doesn't build up and cause problems. We also use special methods to make sure the soil and slope stay put and don't move around. Adding features to the wall that help deal with the pressure from water underground is another smart move. Regular check-ups and fixing any issues early on are also crucial. From what I've seen in my projects, observing the problem from all sides helps us to stop erosion and underground water channels from damaging the wall.

The most important point in my opinion is that water plays an important role in the formation of cracks in the retaining wall. I learned that it is important to detect signs of erosion and plumbing early to keep retaining walls safe. This can be done by monitoring the project during the construction phase. Observing water at the base of the wall, noticing cracks or gaps, or noticing that the floor near the wall is sagging are all warning signs that need to be heeded. By monitoring and quickly addressing these issues, we can avoid larger and more expensive repairs later. My approach is to always be proactive and address issues as soon as they appear to keep the wall functioning and looking good.

Based on my experience, to prevent erosion and piping at the base of a retaining wall, identify the soil type, ensure proper drainage by installing weep holes and a perforated drainpipe behind the wall. Use coarse gravel or crushed stone as a drainage layer to allow water flow while reducing porewater pressure buildup. Adding geotextile fabric (fabric type should be based on project requirement) between the soil and drainage material (i.e. at the interface) prevents soil migration, minimizing the risk of piping. Compact the backfill properly to reduce settlement and water infiltration. Regular monitoring of water levels, as well as checking for any cracks or changes in the wall's condition, is vital for early detection of potential issues.

The correct approach definitely depends on the soil type. First of all, we need to make sure that water does not accumulate behind the wall. Using approaches such as drainage pipes can help water escape rather than forcing it against the wall. Geotextiles can also sometimes be really practical solutions. It is important to design these systems to meet the specific challenges of the site, e.g. B. how much water we expect and what the wall is made of. Then it is another way to make the floor stronger and more stable.

In my experience, one of the most critical steps in managing drainage issues is ensuring proper water flow. Small drainage holes and pipes, tailored to the specific needs of the site, are key in controlling water pressure, which can lead to erosion and piping. It’s imporant to consider factors like soil type, the size of the wall, and expected water levels.

Based on what I've learned, making sure water can drain properly is the most important step to stop these problems. Using approaches like small drainage holes and pipes that match what the wall needs really helps control water pressure, which often causes erosion and piping. It's important to make these drainage systems fit with the site's specific soil, how big the wall is, and how much water we expect. For this reason, I always use geotechnical engineering rules to figure out what to do. Also, making the soil stronger and more stable can also be a practical way.
