| Abstract: | The header tank for the sewage treatment works in Jiaxing is fabricated in 5 sections, sunk through hydraulic mechanic excavation and draining three times. As large diameter well point dewatering is adopted, the depth for drained sinking is down to 29.35 m, breaking the record of drained caisson sinking depth in the soft ground of Shanghai. Described hereby is the whole process of caisson fabrication and sinking. |
