Abstract (en)
The invention relates to a method of constructing a water resistant cast-in-place pile wall and the cast-in-place pile wall thus obtained. The wall is built up by providing a number of primary piles (302) and a number of secondary piles (312) which are intersecting. The wall is made watertight by providing a compression seal in the intersections. This compression seal is obtained by providing a liquid blocking means (320), which is positioned in a holding means (318), part of the armouring (314). Upon contact with water, the liquid blocking means swells and expands in the direction of the intersection, thus creating a compression seal. The compression seals are made at points in the intersection lines different from the end points of the intersection lines and are provided in the concrete piles before hardening of the secondary piles (312) occurs. <IMAGE>
