The units are installed in a trench filled with a special mixture of bentonite and cement with a retarder added to control the setting time. Ground anchors are used to tie the panels or posts to the retained earth to provide stability.See all results for this questionWhat is a diaphragm grab?Grabs are diaphragm wall digging tool consisting of two jaws which can open and close to collect cuttings and take them out of the excavated trench. Jaw outer profiles are fitted with teeth to cut the soil. The excavation work cycle starts with the open grab rested on the ground: thanks to the tool weight and speed, the teeth penetrate the soil.See all results for this question
Diaphragm wall is a continuous reinforced concrete wall constructed in the ground to support major construction activities like the construction of dams, tunnel approaches, deep basements and enclosures.

Technical specifications. Thickness of the wall from 0.5 m up to 1.5 m (0.50 m, 0.60 m, 0.80 m, 1 m, 1.20 m and 1.50 m) Standard depth of the wall up to 35 m, exceptionally up to 55 m and more. The height of the retaining wall can be in excess of 20 . The installation of guide walls to stabilize the soil in the upper diaphragm level and guide the grab is necessary.Diaphragm wall - Designing Buildings WikiDiaphragm wall. A diaphragm wall is a structural concrete wall constructed in a deep trench excavation, either cast in situ or using precast concrete components. Diaphragms walls are often used on congested sites, close to existing structures, where there is restricted headroom, or where the excavation is of a depth that would otherwise require the removal of much greater volumes of soil to Diaphragm Walls | Soilmec S.p.A.Technologies. The DW (Diaphragm Walls) are walls built in the underground starting from the surface. The excavating system consists of a clamshell bucket (grab) with the same thickness of the wall to be built. The excavation is carried out with primary and secondary panels, with bentonite or polymeric slurry.
A diaphragm wall is a reinforced concrete wall that is made in-situ. The trench is prevented from collapsing during excavation, reinforcing and casting by the use of supporting bentonite slurry. The slurry forms a thick deposit (the cake) on the walls of the trench which balances the inward hydraulic forces and prevents water flow into the trench.Diaphragm Wall Grabs (mechanical)Diaphragm Wall Grabs (mechanical) Mechanical grabs are the best solution to excavate diaphragm walls in all soil conditions up to a soil hardness of 70 mPA as light chisseling work is possible.
