The installation of steel sheet piling has been a specialty of H.B. Fleming for over thirty years. Steel sheet pile can be adapted to a variety of uses. The following pictures illustrate excavation support, pollution abatement, bridge abutments, and waterfront bulkheads.
These pictures show water control structures which were used to allow the construction of bridge foundations in dry conditions. Steel sheet pile is the most economical and reliable method of controlling water for the installation of deep foundations under water.
Many times it is necessary to support an excavation which is located adjacent to existing infrastructure or buildings. This picture shows an internally braced cofferdam supporting a 35 foot deep excavation for a combined sewer overflow structure in Augusta, Maine.
Here you see a circular cofferdam that is supported by two cast in place concrete beams that behave much like an arched bridge or culvert. This 20 foot deep cofferdam was used to support an excavation for two clarifiers for a wastewater treatment plant in Bar Harbor, Maine. The circular design allows construction of the concrete clarifiers without interference from internal bracing.
H.B. Fleming has recently begun using a technique of installing helical soil anchors to support sheet pile walls where conventional bracing techniques are impractical or impossible. The soil anchors we are using were developed and are manufactured by A.B. Chance Company of Centralia, MO. The Chance helical anchors are economical, relatively quick to install, and do not require grout pumping like conventional soil anchors.
These pictures show sheet pile walls which are being supported by Chance helical anchors. H.B. Fleming is using an auger mounted on an excavator to install the anchors.
This picture shows long sheet pile being installed to prevent ground water from infiltrating a hazardous waste site which is being prepared for a pump and treat groundwater system.
Steel sheet pile is being used here for permanent bridge abutments. Visit our Design Build page for more information on this application.
This is a waterfront bulkhead constructed for a marina on Lake Winnipesaukee in New Hampshire.
