A tremie pipe is a system that is used to place concrete underwater. Its major application is in piling works, basements, diaphragm walls, caissons, underwater foundations, and so on. A tremie pipe is made of plastic tubes or rigid metal material and the diameter of the pipe ranges from 20 – 30 cm. In the bottom-dump bucket, the concrete is ...
Two-step grouts also must be tremie-placed to ensure the best possible results. In order for a two-step grout to work correctly, the bentonite must be combined with a synthetic polymer to delay hydration time. If done correctly, this will create a 20-percent-solids grout that can be used in water well, geotechnical and geothermal applications ...

ron9876 (Structural) (OP) 11 Jul 11 08:11. PEinc thanks for the input. The tremie slab thickness is limited because of rock at the bottom of the excavation. We are in South Florida and the rock has solution holes in this area so we can't dewater until the tremie has the capacity to resist the bouyant force.

A tremie is a pipe that can use for pouring concrete underwater. Its standard function is in basements, diaphragm walls, piling works, caissons, and underwater foundations. The time pipe length is 300mm, made of plastic tubes. A tremie pipe uses to concentrate underwater in a way that concrete is quelling slowly.
Tremie pipe diameter usually ranges from 8 to 12 inches. End plates or plugs are used when a dry pipe technique is employed for starting the tremie pour. As the pipe is lowered to rest on the bottom, water pressure seals the gasket and the pipe is kept dry. In very deep placements, an open-ended pipe can be set and a go-devil or traveling plug ...

Typical tremie mix design consists of MCC 400KG/m3 cement, max w/c 0.5, 20mm aggregate and sand content >40% of total aggregate content. Slump >175mm or equivalent flow >550. Concrete operations should be scheduled and planned so that the pouring of concrete is continuous and typically one load is required every 10 to 15 minutes.

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. Generally the diameter of a tremie pipe varies from 20 cm to 30 cm. Depending upon the depth of concreting under water we can add more tremie pipe by coupling it …
