Round steel tie rods and connections for sheet pile anchorage in marine structures

Sheet pile walls can be strengthened using horizontal tie rods or round steel tie bars to connect to deadman anchorages allowing taller quay walls for port facilities or abutments. Correct design of anchorage or tie back elements is vital for the stability of the structure as the main cause of failure for tied retaining walls is attributed to the tie rods, walings or anchorage (source BS6349 and US Corps of Engineers). Horizontal tie rods are typically fabricated from round steel bars ensuring loads are safely transmitted from the retaining wall to the anchorage point.

ASDO supply a number of solutions to meet the various anchorage situations encountered in practice. Traditional fixed ‘plate & nut’ connections can be used which initially are very economic but often do not allow for future movement in the structure such as settlement so can fail prematurely. Best practice in sheet pile anchorage design will use articulated tie rods which allow movement of the tie rod from its initial installation line to counter the effects of settlement in the structure. Further safety margins can be built in by using upset forged threads which reduces the stress at stiff sheet pile to tie rod connections.

ASDO offer a range of very long, high-quality, tie rods made of round steel with a variety of connections including; upset threads, forged eyes, forged T-heads and forged spherical end.

The Construction Products Regulation of 2011 (CPR) came into force July 2013 making it mandatory for structural steel elements supplied within the European Union to be supplied CE marked indicating they meet the requirements of European harmonised design codes and are ‘fit for purpose’. ASDO marine tie rods, connections & walings meet this requirement and are manufactured under ISO 9001 and EN1090 independently audited quality systems. This has allowed Anker Schroeder to successfully supply many projects around the world.
