ABSTRACT:
A trench wall section having a finished exposed surface and a method for constructing such a trench wall section involves excavating a trench and simultaneously filling it with shore-up fluid, inserting into the trench a pair of spaced apart vertical partition elements having guide grooves thereon, engaging the ends of a prefabricated plate with the guide grooves and guiding the plate downward into the trench between the vertical partition elements at the side of the trench wall which is later to be exposed by removing the soil, introducing in-situ concrete into the space between the plate and the other side of the trench and between the vertical partition elements and thereby displacing the shore-up fluid, allowing the in-situ concrete to harden into a body which adheres to the plate and to the vertical partition elements, and removing the soil to expose the plate, the associated vertical partition elements and the concrete body which are joined together to form the trench wall section.
