Method for providing a sheet pile wall in the ground and a prefabricated wall element for carrying out such method

摘要

A sheet pile wall is formed in the ground by excavating a first well and then excavating a second well spaced at a distance from the first well. The ground panel between the wells is then excavated to form a trench by using an excavating apparatus which is fitted with tubular guiding elements which are guided by the walls of the first and second wells. A prefabricated wall element having an arched center part is placed in the trench. The prefabricated wall element has edges which have meandering side faces. The edges of the wall element are brought into sealing contact with the walls of the trench, after which the first well is filled with concrete with the side face of the edge of the wall element serving as a shuttering to form a supporting nose engaging the side face.
