Walings

Anker Schroeder can supply complete waling systems to suit a variety of wall configurations. Waling usually comprises of two rolled steel channel sections placed back to back and spaced to allow the tie rods to pass between the channels. This spacing must allow for the diameter of the tie rod and the thickness of any protective material applied to the rod and take into account any additional space required if the tie rods are inclined and need to pass between the walings at an angle.

Anchor connections to a sheet pile wall can be made in two ways – outside the wall or inside as shown opposite. Generally walings placed inside the retaining wall are preferred both for aesthetic reasons and, in the case of a wall in tidal or fluctuating water level conditions, to prevent damage to the waling by floating craft or vice versa.

Placing the waling inside the wall also allows the anchor bar to be connected inside the wall within the pan of a sheet pile. This greatly increases the corrosion protection to the main tie bar connection, see detail Z.

When the waling is placed behind the front wall, it is necessary to use waling bolts and plates at every point of contact between the piles and the waling to ensure load is transferred fully to the waling.
