Immersed tube method for underwater crossings, Civil Engineering

Assignment Help:

Immersed tube method for underwater crossing includes the following basic construction steps:

(i)  Prefabricating long tunnel units (concrete orsteel shell) in a dry-dock or shipyard

(ii) Floating and towing the units with removable bulkhead to site

(iii)Immerse the units in a pre-dredged trench

(iv)Connect the units one by one

(v) Covering completed tunnel with backfill

Steel immersed tunnel is a number of times adopted due to the ease of fabrication and its relative lightness. Furthermore shorter construction time is essential when compared with concrete immersed tubes.
