Soldier piles are steel beams that are built in an H pattern. These beams are often seen at home excavation sites, buildings that have structural issues, and mining operations, but they are also useful in low-budget builds and archaeological sites. A huge advantage of using this soil retention method is that contractors can adapt the wall and make changes as they build the system. The versatility of the system is one of the biggest reasons that builders and engineers use these walls.
Timber lagging is the material that goes between the steel soldier piles. This material keeps soil in place while the soldier piles provide support. The piles are the vertical supports, and the timber lagging provides horizontal load protection. The timber walls are often made with pressure treated wood. The builder can decide whether to add bracing like whales or tiebacks to reinforce the wall when holding back a large load, and are often used:
- Upgrades
- Excavations
- Temporary mining
- Short-term construction projects
- Small jobs requiring a wall
- To hold back soil from the work site
- Strict construction budgets
- Noise regulations require a quiet wall build
- Areas where customizing is important
How Soldier Pile and Lagging Goes In Place
The piles go into the ground about six to twelve feet apart. They are put in place by drilling into the soil. After the piles are in the right location and level, digging begins. Once a large enough hole is ready, technicians secure the lagging to the piles and add any bracing. Next, the workers back fill the hole and use machinery to tamp down the soil making it dense and solid. The wall goes up in sections until the build is complete.
Benefits of Using Soldier Pile and Lagging Wall Supports
- Piles and lagging walls are easy to build
- Construction is quick
- The system is much cheaper than conventional retaining walls
- The walls are customizable
- Workers can make changes during the build if necessary
- Uses standard construction techniques
There are some considerations of the pile and lagging wall system. For instance, a system that is built more than twelve feet above ground needs extra reinforcement. Engineers and architects can design the system with more soldier piles. The additional structures add more support letting the wall handle heavier loads. Areas with significant underground water movement or drainage should have pumps or specific water removal methods in place to protect the wall. In any case, experts need to monitor the soil and observe any movement or changes.
Collecting soil samples and providing a strict analysis of the ground is a vital first step to placing a pile and lagging wall system. Building the soldier pile and timber wall support requires the use of specialty machines and equipment. Workers need extensive training in wall calibration, load settlement, and construction. Some states require specific licenses and certifications for these builds as well.
