Abstract
System for removing sediments from a bed of a liquid environment such as a harbor or a pond, characterized in that it comprises a conduit (30), the lower extremity of which forms a moving suction mouth (31) that is to be placed substantially at the level of the bed, and the upper extremity of which leads into the open air so that said mouth (31) is under atmospheric pressure, said system comprising means for carrying out a local stirring operation (41, 42, 43, 44, 53) within said mouth and discharging means (50, 51, 52) connecting said mouth (31) to the surface of said liquid environment, in which these sediments circulate.

System for removing sediments from a bed of a liquid environment such as a harbor or a pond comprising a conduit, the lower extremity of which forms a moving suction mouth that is to be placed substantially at the level of said bed, and the upper extremity of which leads into the open air so that said mouth is under atmospheric pressure, said system further comprising means for carrying out a local stirring operation within said mouth and means for discharging connecting said mouth to the surface of said liquid environment, in which sediments circulate.
Method for removing sediments from a bed of a liquid environment such as a harbor or a pond, the method comprising at least one iteration of the following steps:
- placing a mobile suction mouth under atmospheric pressure, appreciably at the level of said bed;
- carrying out local stirring inside said mouth;
- and
- discharging sediments from said mouth to the surface of said liquid environment.
