Sometimes an inside berm provides to take the phreatic line.
The width between the parallel piles is h 2 1 50 m.
Design method of double row wall steel sheet pile cofferdam views.
This consists of two straight parallel vertical wall of sheet piling tied to each other and the space between them filled with soil.
A sketch of double wall cofferdam is given in fig 4.

Double walled sheet pile cofferdams.
The gap between walls is filled with soil.
The space between the walls is generally filled with granular material such as sand gravel or broken rock.
They are double wall cofferdams comprising two parallel rows of sheet piles driven into the ground and connected together by a system of tie rods at one or more levels.
They are cofferdams comprising two parallel rows of sheet piles driven into the ground and connected together by a system of tie rods at one or more levels.
The values of earth pressure and its probable distribution against rigidly braced walls have been found to be at some variance with the pattern obtained by anchored yielding walls.
Double walled sheet pile.
198 double walled cofferdams are those in which two parallel rows of steel sheet piles are connected with means of a track or a plurality of steel enclosed purlin brackets.
The space between the walls is generally filled with granular material such as sand gravel or broken rock.
