DRAGAGES HONG KONG / ONGOING PROJECTS
Part of the massive Hong Kong-Zhuhai-Macao Bridge project, the Hong Kong Link Road
project involves the design and construction of
a 9.4km-long viaduct section from the Hong Kong Boundary to Scenic Hill on the Airport Island, supporting dual three-lane carriageways over deep waters.
As the first bridge in Hong Kong designed with
a pre-stress pre-cast pier structure, the project team is faced with a variety of challenges, including severe marine conditions, complex navigation requirements, restricted land access, airport height restrictions, stringent dolphin monitoring works, deep rock head levels, the need to supply concrete using a floating batching plant, and the logistics of transporting concrete trucks on Ro-Ro barges.
The floating batching plant, a first in Hong Kong, facilitates marine production and significantly reduces marine and land traffic, which in turn minimises air and noise pollution.
With sustainability in mind, the project adheres to strict environmental policies regarding air quality, water quality, sediment quality, ecology, fishery, cultural heritage, waste management and noise impact.
Dragages Hong Kong has played a key role in the development of Hong Kong’s airport island. This bridge is our eighth project connected to the airport.
香港接線是龐大的港珠澳大橋工程的一部 份，項目包括設計及建造一條9.4公里長 的雙程三線高架橋，由粵港分界線伸延至 觀景山的跨海通道。
作為全港第一條採用預力預製橋墩組件建造的高架橋， 項目團隊面對多項嚴峻考驗，包括不穩定的海洋環境、 複雜的航道海事要求、有限的陸上通道、機場高度規定、 細密的海豚生態監測工作、較深的基巖層，以及使用 混凝土攪拌船提供混凝土和出動駁船載運混凝土等。
香港首次採用混凝土攪拌船，能大大減低海運及陸運
次數，紓緩空氣及噪音污染。
可持續發展是本項目發展的重要一環，所有工程均嚴格
遵守相關的環保政策，符合空氣、水質、底泥質素、
生態環境、漁業及文化保育、廢物管理及噪音影響的
要求。
寶嘉一直積極參與香港機場島的發展工作，本項目是
團隊投入第八個與香港機場有關的項目。
