Diaphragm wall drilling grab
350-1200 mm | SWHG42 SUNWARD INTELLIGENT EQUIPMENT CO.,LTD.

The Diaphragm Wall Grab is especially designed for diaphragm walls built in the underground starting from the surface, in order to stabilize uncased drill holes. They are performed by digging a trench, filling it with bentonite mud, placing a reinforcement and then displacing the slurry by means of the subsequent concrete casting.

The wall can be used as excavation support, foundation element or as containment structure for the flow of underground water. Diaphragm walls are an important part of the underground construction works also because they can be built with a relatively little disruption degree.
