4ft Tremie Pipe Length, 12in Diameter

What is a Tremie Pipe and why is it used for underwater pouring?

A tremie pipe is a long vertical pipe used in construction to pour fresh concrete underwater or below ground level. The term “tremie pipe” comes from the French word for funnel, it’s a funnel. This pipe ensures a smooth and controlled pour of concrete, where the concrete needs to flow into place without segregation. Made from metal or PVC, tremie pipes come in various diameters and lengths to suit your project. Their main job is to allow the fresh concrete to flow continuously and maintain its integrity and concrete quality during construction underwater.

Tremie Pipe, 12in Diameter for Pouring Concrete Underwater

The Tremie Pipe has thick Polyethylene walls for extra long life

• Tremmie Pipes include heavy duty steel chains and brackets

• Available in two sizes: 12” dia x 4ft and 8” dia x 4ft.

• Made in the USA.

The Tremie Hopper, by Deslauriers, is a specialized tool used in fresh concrete pouring to ensure a smooth and controlled pour of concrete, especially in deep or underwater construction. It’s used for the tremie method of pouring concrete below water or where there’s a risk of segregation or contamination.

The Tremie Hopper is made from high quality materials such as polyethylene or steel to withstand the demands of a construction site and last long. It has a funnel shape with a wide opening at the top and a narrow discharge at the bottom to allow for a smooth and continuous flow of fresh concrete and includes a foam rubber plug.

When you pour concrete underwater, the Tremie Hopper is placed vertically above the pour area. The concrete is loaded into the hopper which acts as a reservoir and provides a consistent and uninterrupted supply of concrete to the pour point. The narrow discharge at the bottom ensures a controlled flow to maintain flow and prevent segregation or debris from entering the concrete.

Each batch of fresh concrete should be poured quickly to maintain flow, prevent early set and get a strong and uniform concrete structure during difficult pours.

One of the main benefits of using a Tremie Hopper is to prevent water from entering the concrete during underwater pour. The hopper maintains a positive pressure at the discharge point to prevent water from entering the flow of concrete and get a homogeneous mix.

Also the Tremie Hopper allows for precise underwater concrete placement in deep foundations, caissons, bridge piers and other submerged or confined structures. The design ensures the concrete is placed in a column without significant free fall, reducing the risk of segregation and maintaining the structural integrity of the final product.

In summary the Tremie Hopper by Deslauriers is a specialized tool used in concrete pouring using the tremie method. It provides controlled flow of concrete, prevents water entry and allows for precise and efficient placement in difficult construction situations. Using the Tremie Hopper ensures successful complex projects and good concrete structures.

Components and Features

A tremie pipe consists of several key components that work together to get the concrete placed efficiently. The pipe itself has thick polyethylene walls for durability and long life. Heavy duty steel chains and brackets are attached to the pipe to connect it to the concrete tremie hopper. At the top of the tremie concrete pipe a conical hopper allows concrete to be loaded, to get a smooth flow into the pipe. The discharge opening at the bottom controls the flow of concrete to get the freshly placed concrete to be deposited accurately and with minimal dispersion. This design helps to maintain the quality and integrity of the concrete during placement.

Applications and Industries

Tremie pipes are used in various construction applications, especially in underwater construction and concrete placement. They are used for underwater foundations, diaphragm walls and piles and in complex structures that require precise concrete placement. Industries such as marine construction, offshore construction, coastal construction, bridge construction and tunnel construction use tremie pipes. They can place concrete underwater and in confined spaces making them a versatile and essential tool in these industries to get stable and durable structures.

Safety Precautions and Considerations

When using tremie pipes, safety precautions and considerations should be followed to get a successful pour. Continuous flow of concrete is key to avoid blockages and maintain the integrity of the concrete during placement. The pipe should reach the exact location underwater to place the concrete accurately. Operators should be trained to operate the equipment and understand the concrete flow dynamics through tremie pipes. Regular maintenance of tremie pipes and accessories is crucial to prevent clogs and damage to get long life and reliability of the equipment. By following these safety measures, you can get optimal results with tremie pipes.
