Timed desilting silt prevention system and method during flattening of immersed tunnel foundation bed
The invention relates to a timed desilting silt prevention system during flattening of an immersed tunnel foundation bed. The timed desilting silt prevention system during flattening of the immersed tunnel foundation bed comprises lifting cables connected onto a vessel body, wherein the lifting cables are used for lifting a desilting device, and the desilting device comprises silt washing device and a silt sucking device. The desilting device comprises longitudinal silt washing pipes and longitudinal silt sucking pipes which are connected onto the vessel body, and transverse silt washing pipes and transverse silt sucking pipes which are in parallel with the foundation bed, wherein the transverse silt washing pipes and transverse silt sucking pipes are provided with a plurality of holes. In a timed desilting silt prevention method during flattening of the immersed tunnel foundation bed provided by the invention, after the flattening of the foundation bed is completed, the desilting device crossing over a foundation trench is lifted through a vessel to remove silt on the foundation bed, the silt washing device sprays water to the foundation bed to float the silt, then the silt sucking device sucks away the silt, repetitive desilting is realized and thereby the silt is prevented from being settled on the foundation bed. By adopting the timed desilting silt prevention scheme during flattening of the immersed tunnel foundation bed provided by the invention and performing timed desilting on the foundation bed, the silt is effectively prevented from being settled on the foundation bed.
