Section abbreviations
| E, Ea, Eb D, Da, Db, Dz Dr, Dra, Drb V | = single pile = double pile = triple pile = quadruple pile |
20, 600, 700 and 750 series
E
D
(S-shape)
Dz
(Z-shape non-standard shape)
Dr
Triple piles of the 700 and 750 series on request.
Larssen 43
(Pay attention to interlock position)
E
D
(S-shape)
Dz
(Z-shape, for wall form 430 only)
Larssen 430
(Wall form of LARSSEN 43)
V
To withstand the shear forces, it is necessary to lock the interlocks on the wall axis.
Handling holes and crimping/welding
Handling holes are provided on request. Each pile back is then provided with a hole as indicated on the drawing. Holes can be provided at a distance of either 75 or 300 mm from the upper pile edge (to be specified when placing the order).
The section moduli stated in this brochure for LARSSEN sections require locking of the pile interlocks either by factory cramping, factory shear-resistant welding or site welding.
Double piles are double crimped at intervals of approx. 0.4 m, triple sheet piles are double crimped at intervals of 0.8 m. Crimps may also be spaced with smaller intervals by agreement.
In the case of displacement of the interlocks, each crimping point is capable of absorbing at least 75 kN at a displacement of 5 mm.
If fabricated piles such as corner, junction and adapter piles cannot be pressed due to technical reasons, they are welded at both ends.
Fitting LARSSEN sections together
1) The same applies to section variants of the same name.
x = Section interlocks do not match.
These details only apply to once-only section replacement.
Always consult us if sections in continuous walls are to be regularly replaced.
