diaphragm wall panel width

Diaphragm walls are underground structural elements commonly

A diaphragm wall is generally constructed in a series of discrete panels typically ranging in length from 3m to 7m. Depths of diaphragm walls vary depending on the application and the specified requirements, but typically they can range from a few meters to tens of meters. The width of the wall can vary from 600mm to 1800mm, again【Get Price】
