Diaphragm walls are executed with the aim of ensuring the stability of deep excavation pits, keeping soil and surcharge loads, controlling settlements around vicinity and the heave on the excavation base. In addition, the diaphragm walls are the most suitable shoring system since they can provide the required impermeability, where there is a high groundwater. The diaphragm walls can be designed and constructed as a temporary or permanent systems.
MULTICELL DIAPHRAGM WALL
This is a special impermeable diaphragm wall application executed in order to perform the excavation in dry conditions. Panels are distributed circularly along the shoring center line. The shoring system; which can be either permanent or temporary, works as cantilever with the help of arching effect of the shoring system without need of horizontal supporting element (anchors/struts etc.).
The Top-Down excavation method is used where the structure is constructed from top to down while excavation is continued, unlike the classical deep excavation applications. The design and construction stages of this simultaneous construction and excavation method; which saves considerable time and cost are different from the conventional excavation systems.
