Methodology
The Lock and Dam was located on the Ohio River between Kentucky and Illinois. All system installations were done with flat deck barges, crane barges, and man-lift barges. The installation of the deep wells was experimental and specifically designed to be able to work off barges. Mersino used a vibratory hammer to install a 14″ x 80′ long steel caisson. Once installed, the 14″ caisson was water jetted out, using a 6″ x 80′ long jet tool powered by a Global 8GSH jet pump. When the caisson was out, a 12″ x 80′ long well casing was installed. The coarse nature of the native soils allowed us to utilize a natural collapse method during well installation. The use of vibratory equipment and jetting methods, combined with working off of barges, made this project unique and challenging. Three 50hp Mody submersibles, ten 20hp Prosser submersibles, two 10hp Prosser submersibles and three 5hp Prosser submersibles were used for this project, installed within the new lock construction within the river itself.
Utilizing heavy equipment on float barges was challenging, but Mersino overcame these obstacles and completed the lock and dam project on budget.
Challenges
The project was slightly delayed due to the location of the install on the river. Utilizing heavy equipment on float barges was challenging, but Mersino overcame these obstacles and completed the lock and dam project on budget.
