FY10 BUFFALO CDF-4 DIKE REPAIR
GROUTING

 

Lancaster, Tennessee

 

ACT was contracted by Zoladz Construction Co. Inc. to provide perform drilling and grouting of the dike. The purpose of the project was to repair portions of the Buffalo Confined Disposal Facility # 4 (CDF-4) perimeter dike. CDF-4 is located in the Buffalo Harbor adjacent to Lake Erie. The dike is designed to contain sediment dredged from the federal navigation channel within the harbor.

 

The work included rotary duplex drilling through the dike to facilitate installation of Multiple Pass Sleeve Port pipes followed by injection of balanced stable grout through the pipes into the dike. Approximately 640 lineal feet of the dike required treatment in order to reduce the permeability of the rockfill dike at location where the existing sheet piling was damaged. Drilling and grouting was completed through each zone of the rockfill dike including the armour stone (10 to 20 ton stones), underlayer stone (0.5 to 2.25 ton stones), core slag (2” diameter to 250 pound stones), and the filter slag (3/4” minus material).

 

IntelliGrout®, a proprietary computer monitoring system was utilized for real‐time electronic monitoring and recording of the grouting. IntelliGrout® provides powerful analytical and graphical tools for production grouting analysis allowing the grouting program to be adjusted in real‐time.

 

ACT is proud to have received a Certificate of Appreciation from the US Army Corps of Engineers Buffalo District for exceeding Safety standards. We completed the project, in a challenging environment, with zero lost time accidents or injuries.
