SHEET PILE WALL
Sheet pile walls are constructed by driving prefabricated reusable panels into the ground. These panels are driven into ground using a vibratory hammer in such a way that each panel interlocks with the adjacent one on each side. Soil conditions may allow the interlocking sections to be vibrated into ground instead of being hammer driven. The series of panels vertically interlock to form a continuous impermeable wall.
The full wall is formed by connecting the joints of adjacent sheet pile sections in sequential installation. Sheet pile walls provide structural resistance by utilizing the full section. The reusable panels are made from a variety of materials such as steel, wood, plastic and fiberglass. Steel sheet piles are however, the most commonly used in deep excavations.
Sheet piling provides an efficient, economical and timesaving solution in certain types of applications such as cofferdams, cut and cover tunnels, retaining walls, seawalls and containment walls. They are however, constrained by the depth of excavation, the magnitude of the lateral pressures, and the stratum they can penetrate.
