Claim:
A combination pile wall comprising a plurality of beam elements, namely, at least one of T-beams and double-T-beams, at least one sheet pile positioned between two adjacent beam elements, and shaped connection strips connecting the sheet pile with the two beam elements, wherein each shaped connecting strip includes a first locking element having two securing strips which project from a central strip of the shaped connection strip between which a corresponding securing section formed on the respective beam element is inserted, and a second locking element that is engaged with a complementary locking element of the sheet pile; the improvement wherein the the two securing strips of the first locking element of the shaped connection strip are arranged such that the first locking element may be pivoted with respect to the securing section of the beam element through an angular range (α) of a minimum ±3° to a maximum ±10°, wherein the ability of the first locking element to pivot is limited when the securing section of the beam element rest against at least two lines of contact at the securing strips of the first locking element, and wherein the second locking element and the complementary locking element of the sheet pile are configured in cross section such that the two locking elements may be pivoted with respect to each other through an angular range (β, χ, δ) of a minimum ±3° to a maximum ±10°.
