Formwork for Concrete - Pagina 15-29
Tremie concrete is placed under water by gravity feed through a vertical pipe with one end above water for charging with concrete and the bottom immersed in the concrete being placed. This type of placement is used for sealing cofferdams ...

Concrete Construction Engineering Handbook - Pagina 15-8
One of the most troublesome problems associated with using a tremie is controlling the head pressure on concrete in the tremie pipe so the pipe does not empty itself too quickly and allow water to enter the pipe from the bottom. Fortunately ...

Port Designer's Handbook: Recommendations and Guidelines
17.2.7 Pump concreting The pump concreting method can also be said to be an extension or a variation of the tremie pipe method. Instead of delivering the concrete into the formwork by the pressure created by the concrete's own weight, the ...

5.4 Concrete placement Critical issues relating to underwater placement in large or deep drilled shafts include the initiation of flow through the tremie and control of concrete during casing removal. Gravity tremie placement is preferred over ...

With the early superplasticisers offering barely 30 minutes "life" from time of addition, only the most optimistic contractor would contemplate tremieing superplasticised concrete, allowing for tremie shortening activities etc. The result was that ...

(13 to 25 mm) diameter tremie tube (usually PVC pipe) is lowered to the bottom of the open probe hole, and a grout slurry is prepared and pumped under pressure down the tremie tube (Figure 6.102). This method assures that undiluted grout ...

Underwater Soil Sampling, Testing, and Construction Control
Tremie Concrete Construction Concrete placed underwater by tremie methods is widely used for drilled piles, piers, or walls placed in water-bearing materials; seals in cofferdams; closing of caissons; and underwater construction of reinforced ...

In this way the concrete in the pipe is always under a higher pressure than the water outside it and is unlikely to be diluted by water. Placing by a tremie prevents segregation of the concrete, and closely resembles the placing of the grout in ...

Practical Handbook of Ground-Water Monitoring - Pagina 321
In wells more than about 50 feet deep, granular bentonite may be mixed with water and conveyed through a tremie pipe from the surface directly to its intended depth in the annulus; pelletized bentonite is not effectively installed through tremie ...
