The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4]The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water above it, thus limiting washing out of the cement content of the fresh concrete at the exposed upper surface.
Once a particular depth of trench is reached, a reinforcing cage is lowered into the slurry-filled pit and the pit is filled with concrete from the bottom up using tremie pipes. The heavier concrete displaces the bentonite slurry, which is pumped out, filtered, and stored in tanks for use in the next wall segment, or it is recycled.
A tremie is a vertical, or near-vertical, pipe with a hopper at the top used to pour concrete underwater in a way that avoids washout of cement from the mix due to turbulent water contact with the concrete while it is flowing. This produces a more reliable strength of the product.
Due to the presence of groundwater when the piles were bored, a Tremie pipe was used which displaced water to the surface as the bore hole was filled with concrete. At the southwest corner of the site, where the automated car stacking system was to be installed, BSL removed the large diameter auger piles and replaced them with 24Nr, 273 mm (1 ...

Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
Tompkins would have to construct a 10 feet (3.0 m) thick artificial bottom in order to proceed. To deposit in accordance with the contract, a tremie would be needed. A tremie is a pipe that concrete is passed through so it doesn't contact the water and disintegrate. [5]
