摘要

The process consists of a bar of the flexible envelopes 20 aligned and contiguous, to descend the rudder bar until it rests on supports with the envelopes in the bottom 23 of a trench, by pouring the concrete into the envelopes in successive layers 31.1 to 31.4 and alternately in one direction (arrow f) and in the opposite direction (arrow g), to close the envelopes and to detach, to move the bar to the next memory location.
