What is the tremie?
Tremia refers to the method of casting concrete underwater or in dry spaces deep below the ground. The tremie can also refer to the main piece of equipment used to direct this concrete pouring. The Pour Tremie allows the concrete to be successfully adjusted and dried and helps to maintain moisture far from the wet concrete mixture. First, suppliers create a standard form of metal or composite materials. This form must correspond to the size and shape of the constructed object. The metal plate is attached to one end of the mold, then the whole object is lowered until it reaches the seabed. The board at the form of the mold should be firmly connected so that no water can enter the form.
Next, the installer reduces the grout or the tremies down to the form base. One end of the pipe must stay close to the seabed, while the power is equipped with a large basket or hopper to capture freshly mixed concrete. The mixture of the mixed car of concrete empties the mixture into the hopper and wet concrete travels along the length of the TREmie to fill in the form base. Installors must keep the bottom of the pipe in contact with fresh concrete for all the best results.
When the pouring is complete, the pipeline rises up and out of the form. The concrete is allowed to dry on the type of mixture used and tests can be carried out to determine whether the concrete has been safely cured. Depending on the application, the forms may be removed or simply left in place.
The trim method is also used to seal underground layers. The gasket around a well with concrete or inject prevents the well from becoming on itself, and also prevents unwanted surface water contaminating water supply. Tremie pumps wet boxes into the base around the well cover until the mixture reaches the ground level. Once the jointing pipe is removed, the installer simply drill the base of the cover and the surrounding concrete to get into the water for the well.
some canWonder why the tremie is even needed. Although it is easy to pour concrete into a mold above the water level, this generally leads to a very poor finished product. Falling concrete is no longer correctly mixed as soon as it settles into the form base, resulting in a cavity or air pocket that could lead to failure.
