SHEET PILES RETAINING WALL
SHEET PILES RETAINING WALLINTRODUCTIONAre thin interlocking steel sheets used to construct a continuous barrier in the ground.Interlock is typically achieved by clutching the edge of one pile into previous pile.Cold- rolled section have a weaker interlock than hot-rolled section.One of the main application for sheet piles is for temporary retaining wall of cofferdams used to allow permanent in ground construction to be undertaken.Driven sheet are often installed by vibrating hammer operated of leaders mounted on tracked base machines or suspended from crawler cranes.Piling contractors installed driven steel piles up to 25m in length with individual pile weight up to 5 tonnes.ADVANTAGEProvide high resistance to driving stresses. Light weight.Can be reused in several project.Long service life above or below water with modest protection.Easy to adapt the pile length by either welding or bolting.Joins are less apt to deform during driving.
DISADVANTAGESSection can rarely be used as part of the permanent structure.Installation of sheet pile is difficult in soil with boulders and cobbles. In such cases, the desire wall depth may not be reach.Excavation shapes are dictated by the sheet pile section and interlocking element.Sheet pile driving may cost neighbourhood disturbance.Settlement in adjacent properties may take place due to installation vibrations.
MATERIALSSteel (Various types; hot-rolled and cold-rolled piles)Concrete (thickness 6-12 inches, 30-48 inches width)Wood (for short wall)Vinyl (lower wall or anchored wall)Fiber Reinforced Polymer (fiberglass or composite sheet pile)
