Abstract
The invention relates to apparatus and methods for constructing diaphragm walls. A guideway tube is provided for casting into a concrete panel along a height of a face of the concrete panel, comprising: an elongate guideway track comprising at least one elongate side wall and an elongate slot along the at least one elongate side wall, the elongate slot having a first width; and, an elongate closure panel comprising: a rear panel portion configured to close the elongate slot enclosing an elongate internal volume, and, a front panel portion of a second width greater than the first width. Preferably the rear panel portion is a close fit within elongate slot sufficient to resist the ingress of slurry and concrete. Preferably the rear panel portion is configured to engage the elongate slot in a manner configured to resist compression forces.
