In geotechnical engineering, ground retention is often required to ensure stability and safety during excavation for construction projects. One of the most widely used solutions for this purpose is the Berlin-type retaining wall, a system that combines efficiency, cost-effectiveness, and rapid installation.
What is a Berlin-type retaining wall?
A Berlin-type retaining wall is a retaining system that uses vertical steel piles installed into the ground, with timber lagging or precast concrete panels placed between them. This system provides lateral support to the ground, preventing soil movement and maintaining excavation stability throughout construction.
The installation process typically consists of the following stages:
- Hincado de Perfiles Metálicos:
Los perfiles de acero se introducen verticalmente en el terreno con una distancia regular entre ellos. - Colocación de Tablones:
Se insertan tablones de madera o elementos prefabricados entre los perfiles, ajustándolos a medida que se excava el terreno. - Installation of steel piles Steel piles are installed vertically into the ground at regular spacing. Installation of lagging Timber lagging or precast concrete panels are placed between the steel piles as excavation progresses. Stabilization with anchors or struts Depending on the excavation depth and ground conditions, ground anchors, tiebacks, or struts may be installed to reinforce the retaining system and transfer the applied loads.
Advantages of a Berlin-type retaining wall
- It is a cost-effective solution compared with many other retaining systems.
- It allows excavations to be carried out efficiently thanks to its relatively fast installation.
- It can be used in a variety of ground conditions, particularly in sands and fine-grained soils.
- The steel piles can be removed and reused on future projects.
