2015/7/7The pile bore is then drilled out to a nominal diameter. The open bore is supported by either the soil strength, a bentonite suspension or a steel liner. The reinforcement cage is lowered into the bore and then the concrete poured (either free-fall or through a tremie pipe). Get price

What is Bored Piling (Wet Process)? – PAT

During concreting the tremie pipe must stay in the trench until concreting is completely finished and concreting must be done continuously. Once the volume of concrete in the trench increases the tremie pipe must be taken out but always leaving at least 2m or 3-5m depending on the situation at hand, until all the slurry has been replaced by concrete.

HOW CONCRETING IS DONE UNDER WATER BY TREMIE

2015/4/5Tremie 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 with one another. Get price
