The most common method of handling concrete under water is by tremie. A tremie consists essentially of a vertical steel pipeline, topped by a hopper and is long enough to reach from a working platform above water to the lowest point of the underwater formwork.
How Do They Pour Concrete Under Water?
Concrete is one of the most widely used construction materials in the world, and its use has expanded to underwater applications as well.
While it may seem counterintuitive to pour concrete underwater, it is actually a relatively straightforward process that has been used in a number of different ways.
In this article, we will explore how they pour concrete under water and discuss the benefits and challenges of this approach. The process of pouring concrete underwater starts by preparing the area for the concrete.
This includes excavating the area and preparing the formwork. Once the formwork is in place, the concrete is mixed and delivered to the site. The concrete is then pumped through hoses into the area where it will be poured.
To ensure that the concrete remains dry, a slurry is added to the water. This slurry is a mixture of water, air, and cement, which helps to create a protective layer between the concrete and the water.
Once the concrete is in place, it must be vibrated to ensure that it is properly compacted. This is done with a vibrator, which is a specialized tool that is designed to shake the concrete and remove any air pockets.
After the vibrator is done, the concrete is allowed to set and cure. One of
