Shoreline Storage Tunnel听 |听 Cleveland, OH

A new CSO tunnel in Cleveland was constructed as part of Project Clean Lake, a 25 year clean water initiative to keep the waterways of Lake Erie clean. We were contracted to install three deep diaphragm wall access shafts at three sites along the tunnel alignment to launch and retrieve the TBM.

Portland CSO Basin听 |听 Louisville, KY

The Portland CSO Basin was one of many constructed by the Louisville and Jefferson County Metropolitan Sewer District to control overflows. We were contracted to construct a 42-inch thick unreinforced concrete diaphragm wall to act as the support of excavation shaft.

What are diaphragm walls?

Diaphragm walls are used to create temporary or permanent deep foundations and earth retention walls for deep basements, shafts, parking garages, marine structures, dams and permanent cutoff walls.

How do they work?

Also known as slurry walls, diaphragm walls are formed when deep trenches are excavated into the soil, where reinforced concrete is then placed. Mechanical or hydraulic clamshell grabs or hydrofraise mills are used to excavate the panels, and then the trenches are stabilized by the use of a supporting slurry.

Why do you need diaphragm walls?

Diaphragm walls can be used for earth retention schemes for highway and tunnel projects, as permanent walls for deep shafts for tunnel access and as permanent cut-off walls through the core of earth dams.

Did you know?

The Portland CSO diaphragm wall contains no reinforcing steel, but is held together by compression hoop stresses.
