What is porridge?
Walls
are impermeable barriers that can be used to prevent an unstable ditch to collapse or stop groundwater in the entrance to a specific area. This technique involves digging the ditch and filling cough clay and water. In order to facilitate the construction of underground structures, the main purpose of the mash wall is to prevent unstable soil from collapse before pouring the concrete. The same technique can be used to control the flow of groundwater in therapeutic systems and areas where subsurface contamination has been contaminated, although in these cases the sludge wall must be dug into a certain depth and is usually replaced by concrete. In both cases, the porridge is a semi -flexible mixture usually made of clay and water. Strong suspension is strong enough to help maintain the integrity of the ditch dug in the soft ground, lighter than concrete and impermappled groundwater. Each of these functions is essential for the construction of an effective mash wall.
In construction projects, the walls of the porridge can be used to facilitate pouring large underground concrete structures. If the ground is solid, it is possible to simply dig a ditch, lower in the form and then pour the concrete to create a wall. When the country is soft, saturated with water or otherwise unstable, the unsupported ditch will tend to collapse. In order to support such a ditch until the concrete can be poured, the mash is pumped as soon as the excavation occurs. When the concrete is later pumped to the bottom of the ditch, it naturally pushes lighter porridge.
The unmoved nature of a mixture of clay and water can also be used in the projects of land remediation and other activities that require control of groundwater flow. For this type of porridge wall, the moat that contains must be dug well enough to contact the naturally occurring layer of impermeable rocks or clay. The water will then tend to flow around the porridge, because the clay is already saturated and will not be able to walk under it because of the rock or clay below it. This can be afterto use clean groundwater to be redirected around a contaminated place or to a complete area of the area. If the contaminated area is properly surrounded by the porridge walls, the soil can undergo remediation processes.
