A contiguous pile wall, also known as a secant pile wall, is a type of retaining wall made up of a series of overlapping piles. The piles are drilled and installed in a sequence, creating a continuous wall. The piles can be made of reinforced concrete or steel and are typically installed using a drilling rig. The wall is designed to provide lateral support to the soil and prevent the collapse of an excavation or slope.
A contiguous pile wall is an effective and versatile solution for constructing underground structures such as basements and tunnels. It can also be used in above-ground applications such as bridge abutments and retaining walls. The wall can be designed to withstand different types of soil and ground conditions, making it a reliable choice for a variety of construction projects.
