Retaining wall

A retaining wall (with appropriate retaining wall construction ) is a building which serves to secure the incision and embankments. For this reason, we find support walls often at the edge of traffic lines or waters. In most cases, for reasons of space was a safe Abböschen not possible, also may be necessary due to the space saving a lesser land acquisition. If the retaining wall higher than 2.0 m, the stability must be demonstrated by a static calculation. The static system is loaded mainly by the attacking earth pressure of the slope. To improve the stability of a rear anchoring is possible by ground anchors. Support structures can also be designed as reinforced earth system. For this purpose, the stability of the soil is achieved by geogrids or steel bands, so constructions can be carried out with a slope angle of up to 85 °. The steeper variations from 60 ° point here, however, on its own outer skin system in the form of, for example, concrete blocks or gabions.

Types

There are different types of retaining walls:

• Pile wall
• Drywall
• Gravity dam (also: gravity dam ), eg gravity dam
• Krainer wall
• Plastic - reinforced soil ( CFU )
• Backpack wall
• Bulkhead
• Drywall
• Cantilever retaining wall and walls of L- stones ( "wall washers " )
