Document Type and Number:
WIPO Patent Application WO/2022/095494
Kind Code:
A1
Abstract:
A dry desilting method for a riverway. In a working process, a river channel must be locally cut off, to allow both banks to have a certain amount of space and facilitate riverway desilting. Furthermore, riverway desilting is thorough, desilting depth is easy to control, sludge concentration is high, transportation costs are low, and engineering costs are relatively low. In the overall process, river channel desilting is carried out in segments, early-stage preparation and later-stage working is carried out at the same time, and the working process is efficient and rapid, thus both ensuring the smoothness of the river channel desilting project, and ensuring that impact on the surroundings is reduced to a minimum.
