There are several advantages to using a contiguous pile wall in construction projects. Firstly, the wall provides excellent lateral support and prevents soil movement and collapse. This is particularly important when excavating in urban areas where nearby buildings and infrastructure could be affected by ground movement.
Secondly, the wall is versatile and can be designed to suit different soil and ground conditions. This makes it a reliable choice for a variety of construction projects.
Thirdly, the wall is relatively quick and easy to install. The piles can be drilled and installed using a drilling rig, which can work in confined spaces and has a low noise level. This means that construction can continue in areas where noise and disruption need to be minimized.
Fourthly, the wall is a cost-effective solution compared to other types of retaining walls such as sheet pile walls. The overlapping piles reduce the amount of excavation required, which reduces the amount of material that needs to be removed from the site.
Finally, the wall is aesthetically pleasing and can be finished in a variety of materials such as concrete or stone. This makes it a popular choice for public spaces and urban regeneration projects.
