Understanding the Diverse Applications of Diaphragm Walls in Civil Engineering Practice

A diaphragm wall is wall made of plain or reinforced concrete, which is constructed in a trench excavated in the ground.

Some typical applications of diaphragm walls are:

  • Deep Basements: Diaphragm walls are commonly used to create deep basements in urban areas where space is limited. The walls provide support against lateral soil pressures and groundwater while allowing for the construction of underground structures.
  • Underground Car Parks: Diaphragm walls are used in the construction of underground car parks, providing structural support and preventing groundwater ingress.
  • Retaining Walls: Diaphragm walls are used as retaining walls to support vertical or near-vertical soil slopes. They are particularly suitable for deep excavations where lateral stability and groundwater control are critical.
  • Flood Protection: Diaphragm walls can be used as flood protection barriers. They are built along riverbanks or shorelines to prevent flooding and protect infrastructure and inhabited areas.
  • Water and Wastewater Treatment Facilities: Diaphragm walls are used in the construction of water and wastewater treatment facilities, such as pump stations and water storage tanks. They provide structural support and act as containment walls.
  • Underground Metro and Railway Stations: Diaphragm walls are commonly used in the construction of underground metro and railway stations. They provide structural support, prevent groundwater ingress, and act as noise barriers.
  • Tunnels: Diaphragm walls are utilized in tunnel construction to provide temporary or permanent support during excavation. They can serve as tunnel walls, shaft walls, or cut-and-cover tunnel elements.
  • Deep Foundations: Diaphragm walls can be used as deep foundation elements to support tall structures or bridges. They provide lateral support and transfer loads to deeper, more competent soil layers.

It’s worth noting that diaphragm walls require specialized equipment and expertise for their construction. The specific application and design of diaphragm walls depend on site conditions, engineering requirements, and project specifications.
