Construction
The original riser plan for intake/outtake tunnel of the Sydney Desalination project is to set the riser vertically direct above the tunnel through the crown. During design/construction stage the design is changed so the riser will now be sitting approximately 8m from the TBM tunnel hence a lateral gallery connection would be required to joint the riser and TBM tunnel. The reason for this change includes the construction accuracy and saftey. For example it is difficult to maintain accuracy of the marine construction platform to relocate exactly on the prefered riser drilling position. The TBM is also running a risk be excavating under a fully saturated riser. Hence a more work involved solution of constructing the riser 8m from the side wall is used.....

去年到黃金海岸擔任隧道工程師時,Tunnel Boring Machine已經進行了200M,很多組裝的細節部分,以及鑽頭的構造都沒有機會見到,渾渾愕愕的在黃金海岸待了8個月,機械的原理與運作都還不甚了解。這次很幸運的趕上機械阻立的日期,有機會見識到整個機械的吊組和調整,學習到了不少東西。(左圖)海水淡化場施工鳥勘圖
