Method and assembly for constructing a diaphragm wall
A method is disclosed for constructing a diaphragm wall by casting alternate primary (10, 11) and secondary (20) panels in the ground. The primary panels (10, 11) are excavated and cast first, and a cutter joint (15) or similar jointing profile is then milled into the side faces of the primary panels (10, 11) before casting the secondary panels (10). The primary panel casting regions are prepared for casting by positioning sacrificial displacement elements (31) in the regions where joint milling is to be performed. The sacrificial displacement elements (31) may be hollow elements or blocks of relatively easily millable material such as lightweight concrete. Primary panels (10, 11) cast in this way can be milled more easily, and particularly when the milling tool is at an angle to the surface being milled.
