Abstract (en)
In a method and device for building a wall (43; 120; 150, 152, 154; 156, 158; 160; 160a, 160b; 161a; 162; 170, 172; 192, 192a-192i; 234; 252) or a part thereof in the ground (2), the method comprises pulling the wall building device (30; 60; 110; 160c; 178; 222, 222a-222d) through the ground. The ground adjacent the wall is left substantially intact. The wall building device has cross-sectional dimensions being substantially equal to the dimensions of at least a part of the cross-section of the wall or wall part. The wall or wall part is formed by injecting a hardenable material (44) behind the wall building device. The ground in the area adjacent the front part of the wall building device is removed and discharged. <IMAGE>
