A tremie is a watertight pipe, usually of about 250 mm inside diameter (150 to 300 mm), [1] with a conical hopper at its upper end above the water level. It may have a loose plug or a valve at the bottom end.

The concrete should have sufficient flowability to flow smoothly through the tremie pipe and reinforcement to be used for the tremie method. Together with flowability, tremie concrete should comply with other requirements, which are combined in the general term “workability”.

Jun 15, 2024 · The tremie method is a reliable and effective way to place concrete, utilizing key components such as a concrete hopper and tremie pipe for proper concrete placement. Regular cleaning & storage of tremie is essential for optimal performance when using them in bridge/pier construction, diaphragm walls, or foundations.

Apr 6, 2015 · Tremie method is the most acceptable method of concreting under water. In this method a tremie pipe is inserted in the water up to the point where concrete is going to be placed.

Constructing and maintaining tremie pipes are critical processes to ensure their reliability and effectiveness in concrete placement, especially in deep foundations or underwater structures. Here’s a detailed guide on how tremie pipes are constructed and maintained: Choose right tremie pipes. Material Selection:

In the tremie pro c e s s , concrete is placed through a ve r tical steel pipe with an open, funnel-shaped upper end. The lower end of the tremie is kept immersed in plastic concrete so that freshly placed concrete doesn’t come into contact with the water.

The primary purpose of the Guide to Tremie Concrete for Deep Foundations (Tremie Guide) is to give guidance on fresh concrete characterisation with respect to its performance, the concrete mix design process, and the methods used to test the fresh concrete. The principles of …

The Tremie method is a technique used for placing concrete underwater or in situations where water is present during the concreting process. It involves the use of a large pipe called a Tremie pipe to deliver the concrete to the desired location underwater.

Jul 20, 2024 · A tremie system is composed of several integral parts that work together to ensure the effective placement of concrete in challenging environments. At the heart of the system is the tremie pipe, a long, rigid tube typically made from steel or plastic.

Apr 5, 2016 · The primary purpose of the guide is to present design considerations (concrete rheology, mix design, reinforcement detailing, concrete cover, etc.) and best practices for tremie concrete placement for drilled shafts and diaphragm walls that promote construction of high quality elements.
