Soldier pile and lagging walls are the techniques in shoring which has been used in the contruction industry for a long time. Since the 18th century, these systems have been used in Berlin, Newyork and Lond successfully. When steel and timber lagging is utilized, the systems is known as Berlin Wall.
Caissons, circular pipes, or concrete piles can also be used as soldier piles but the construction of the shoring system will be higher that soldier piles. Despite the effective utilization of the concrete pannels, timber lagging can also be used. Soldier piles are formed by constructing piles at regular spacing (1.82m to 3.65m) , excavating in small stages and installing lagging, backfillig and compacting the void space after lagging.
Soldier piles solely provide the moment resistance in the soldier pile walls and lagging walls. By embedding the soldier piles beneath the excavation grade, passive soil resistance can be achieved
Moment resistance in soldier pile and lagging walls is provided solely by the soldier piles. Passive soil resistance is obtained. The lagging bridges and retains soil across piles and transfers the lateral load to the soldier pile system.
Unlike other retaining walls, soldier pile and lagging walls are the most cost effective systems. They easy to be mobilized providing easy installation. Soldier piles are advantegous from many aspects;
- Soldier piles are easy to install
- Soldier pile construction is cheaper unlike other systems.
- Soldier pile installation is versatile and adjustments can be made in the field easily to accomodate revisions.
- Lagging construction can be easy and fast
- Advanced construction techniques are not required while constructing soldier pile and lagging walls
