Diaphragm walls

In the production of cast-in-situ concrete diaphragm walls, the use of the correct stop-end-elements plays an enormously important role, especially with regard to watertightness. Especially for wide diaphragms (B 800 mm and larger), the use of stop-end-elements is mandatory, as otherwise the reinforced diaphragm length is greatly reduced (e.g. …

Equipped with a permanent measuring and control system, any deviation from a vertical excavation direction can be immediately detected and corrected with the hydraulic diaphragm wall grab HSWG. This ensures high accuracy even at greater depths (> 50 m) and perfects the production of diaphragm walls with grabs. The hydraulic diaphragm wall grab …
