(54) Title: DIAPHRAGM WALLS (57) : The invention relates to apparatus and methods for constructing walls, in particular concrete embedded retaining walls such as diaphragm walls, comprising one or more panels, and walls so constructed. In particular the invention relates to apparatus, methods and walls, in particular concrete embedded retaining walls such as diaphragm walls, and kits (comprising)a guideway. In one aspect there is provided aguideway tube(32)for casting into a concrete panel (24, 26) along a height of a face of the concrete panel (24, 26),comprising:an elongate guideway track (50) comprising at least one elongate side wall (33) and an elongate slot (44) along the at least one elongate side wall (33), the elongate slot (44) having a first width (W1); and, an elongate closure panel (70) comprising: a rear panel portion (72) configured to close the elongate slot (44) enclosing an elongate internal volume(V1), and,a front panel portion (74) of a second width (W2) greater than the first width (W1). Preferably the rear panel portion (72) is a close fit within elongate slot (44) sufficient to resist the ingress of slurry and concrete. Preferably the rear panel portion (72) is configured to engage the elongate slot (44) in a manner configured to resist compression forces.The invention also describes a guideway tube, an apparatus, a guideway track, a method, a wall, and a kit.
