Underwater Concreting: Uses, Performance, Methods

Underwater concreting by the tremie process is ideal for pouring vast amounts of strong flowable concrete. The concrete is delivered to the hopper by either injection, belt conveyor or skips. Tremie tubing, which is attached to the upper end of a hopper and constantly immersed in fresh concrete, is used to bring concrete from a hopper to the surface at the same spot.

Underwater Concreting: Uses, Performance, Methods.

21-04-2020  Significant recent advances by the engineers in the building of locks and dams underwater involve the in-the-wet construction process. Underwater Concreting utilizes concrete precast structures as the in situ process in which concrete is specifically mounted underwater. The underwater concrete is designed to interact with the precast concrete in a composite shape.

02-04-2021  Underwater concreting using tremie method is convenient for pouring large amount of high flowable concrete. The concrete is moved to the hopper by either pumping, belt conveyer or skips. Tremie pipe, which upper end connected to a hopper and lower end continuously submerged in fresh concrete, is used to place concrete at the exact location from a hopper at the surface.
