Retaining Wall Rehabilitation

 

Location:
Historic Community in Eastern Maryland

Project:
Rehabilitation of 350 lineal feet of deteriorated and displaced retaining walls and embankments

General Contractor:
Coastal Drilling East (CDE), a Shaft Drillers International company. CDE managed the design of the project and anchoring as well as the related work, including site prep, traffic slope stability analysis, maintenance, protection of existing structures, fencing, excavation / embankment, and concrete construction.

Situation:
The town lies adjacent to the Susquehanna River. Massive rock outcrops lie between the steep side streets and the river bank below. A century old, hand laid rock wall supported the only access road serving a small cluster of homes. The narrow road also supported a number of buried utilities.


Solution:

CDE proposed installation of rock anchors with a cast in place concrete facing to stabilize the deteriorating walls. Due to the limited work area, steep slopes, and the fact that the road could not be taken out of service, CDE modified its specialty drilling equipment to accommodate the logistical challenge. Partnering with a major geotechnical engineering firm enabled CDE to tailor a design for its specialty equipment and processes.





Results:

Successful installation of approximately 100 anchors now support the existing wall, the weight of the facing wall, and the rehabilitation of the existing street.
