SHEETING & SHORING
SOLDIER PILE & LAGGING
Soldier piles (beams) and lagging are excavation support techniques where vertical steel piles, either driven or grouted into drilled holes, are placed at regular intervals along the proposed-wall location. Wood lagging (sometimes steel or concrete panels) are placed in between the soldier piles as excavation proceeds. Lower height walls are typically cantilevered. Higher walls can be tied-back or braced where additional lateral support is required.
Soldier pile shoring is very versatile because the size of the piles and the spacing can be adjusted to suit the site soil conditions. In many cases, this is the most cost-effective method of site shoring.
Cofferdams are structures that retain water and soil removed from an enclosed area in order for the enclosed area to be excavated dry. Cofferdams are commonly used for the construction of bridge piers and other support structures built in water. Cofferdams walls are usually formed from sheet piles that are supported by walers, internal braces and cross braces.
Cofferdams are typically dismantled after permanent works are completed. Since cofferdams are usually constructed in water, the sheet piles are installed using preconstructed templates that permit the correct positioning of each sheet pile from a barge.
Sheet piles are interlocking steel sections that are driven into the ground to support excavations or solid removal. Sheet pile walls can be of either a permanent or temporary nature. A wide range of materials, steel, plastic, vinyl or concrete can be installed using a Silent Piler and hydraulic or vibratory hammers. Interlocking sheet pile walls are used for many applications including cofferdams, basement walls, pits and marine bulkheads.
