Tower/Pneumatic
Caisson/Sinking and Excavation |
 |
|
| |
| To sink the caisson
into a required depth, sinking and excavation was
performed in the working chamber located at the
bottom of the caisson. The pneumatic caisson method
has been associated with the caisson disease that
caused by long working hours under high air pressure
or insufficient de-pressurizing time after working
under high air pressure. In the construction of
the Bridge, the risk of the caisson disease was
reduced by employing the unmanned excavation system.
