Lehtplaadid

Lehtplaadid, often translated as sheet piling, are structural elements used in civil engineering and construction. They are typically pre-fabricated, long, flat sections of material, most commonly steel, that are driven into the ground in a continuous wall. The interlocking nature of the edges of adjacent sheet piles creates a barrier that is impermeable to water and soil. This makes them ideal for a variety of applications where excavation is required below the water table or where retaining soil is necessary.

The primary function of lehtplaadid is to provide temporary or permanent support for excavations. They are widely used in the construction of retaining walls for basements, subway tunnels, and docks. Their ability to resist lateral earth pressure and water ingress makes them a cost-effective and efficient solution for these challenging environments. They can also be used to create cofferdams, which are temporary enclosures that allow construction work to proceed in dry conditions within a body of water.

Lehtplaadid come in various shapes and sizes, with different interlock designs to suit specific project requirements. The material used, typically steel, offers good strength and durability. Installation is usually achieved using vibratory hammers, though impact hammers or hydraulic presses can also be employed. Once installed, the lehtplaadid wall acts as a continuous, watertight barrier. The design and selection of lehtplaadid depend on factors such as the depth of excavation, the type of soil, and the expected hydrostatic pressure.
