Slurry wall installation with grab

Slurry wall with grab
Production steps of a slurry wall panel made of reinforced concrete:
1. Excavation using a slurry wall grab with addition of support suspension
2. Installation of the stop-end pipes
3. Insertion of the reinforcement
4. Installation of the concrete applying the tremie method with simultaneous pumping out of the support fluid
If slurry walls are installed with a grab, a two-jaw slurry wall grab suspended on a duty cycle crawler crane excavates the slurry wall panels. Mechanical grabs are opened and closed via rope, hydraulic grabs via hydraulic cylinders. Hydraulic grabs can additionally be fitted with flexible guiding strips on the grab frame which allow to align the grab within the trench.
