Immersed tube tunnel foundation bed geotextile bulkhead segmented type covering silt-prevention system and method
The invention relates to an immersed tube tunnel foundation bed geotextile bulkhead segmented type covering silt-prevention system which comprises a bulkhead geotextile desilting device and special vessels. The bulkhead geotextile desilting device comprises bulkheads, steel wire ropes, steel tubes and geotextile, the steel tubes are arranged at the two ends of the geotextile, the two steel tubes are connected with each other through the steel wire ropes, the geotextile is arranged above the steel wire ropes, and the periphery and the middle of the geotextile are connected with the steel wire ropes and the steel tubes respectively through buckles; The special vessels comprise two geotextiles-laying vessels, each geotextiles-laying vessel is connected with the desilting device by lifting the steel wire ropes. By means of the immersed tube tunnel foundation bed geotextile bulkhead segmented type covering silt-prevention scheme, the influence on construction caused by too large amount of siltation can be avoided, the siltation is thoroughly separated from a foundation bed, and meanwhile it is guaranteed that leveled foundation bed is not damaged when desilting is conducted.
