DRAGAGES HONG KONG / ONGOING PROJECTS
Dragages was selected to construct one of
Hong Kong’s most technically challenging tunnels – part of the 6km extension of the ongoing Shatin to Central Line – from Kowloon to the transit hub on Hong Kong Island.
The main scope and challenge of the project is to construct the Eastern Tunnels and Western Tunnels by Tunnel Boring Machine (TBM), as both tunnels go through the city’s busiest districts. Meticulous project planning is essential in aiding the TBMs to navigate through a large volume of pile obstructions and utilities with zero interruption of services to citizens. To cope with the complex geological conditions, two different types of TBMs are being employed for excavation –
a slurry TBM and an Earth Pressure Balanced (EPB) TBM.
The construction of the South Ventilation Building requires careful effort as well, as the existing Police Officers’ Club (POC) needs to be demolished and reprovisioned on the top of the South Ventilation Building.
寶嘉獲選承建香港建造史上其中一項最具 3a 技術挑戰性的隧道項目 —— 全長6公里， 從沙田貫通九龍直達港島心臟地帶交匯 樞紐的沙田至中環綫 (沙中綫) 的其中一段
延綫。
工程主要範圍及挑戰在於以隧道鑽挖方式建造東面及 西面隧道，穿過城中最繁忙的地區。為完成使命， 工程人員需小心規劃隧道鑽挖機路線圖以避開大量樁柱 障礙物及公共建設，並確保不影響各樣設施的服務。 為應付複雜的地質環境，工程需起用兩款不同類形的 隧道鑽挖機 —— 泥漿盾式及土壓平衡式隧道鑽挖機。
興建南通風大樓同樣需要周全準備，工程需拆卸現時的
警官會所，並在南通風大樓竣工後於大樓上重置。
