DRAGAGES HONG KONG / RECENTLY COMPLETED PROJECTS
The East Tsing Yi Viaduct is an essential connection between Nam Wan Tunnel and Stonecutters Bridge. It is an integral part of the road network development to divert busy traffic between the airport and
the city centre.
The joint-venture was mainly responsible for constructing a three-lane dual carriageway, as well as associated works including viaduct ramps, roadworks, drainage, slope works, landscaping and environmental mitigation measures.
Pre-cast box girder segments were predominantly used for the viaduct and were erected using the balanced cantilever method to ensure maximum time efficiency and minimal environmental impact.
In total, 18 pre-cast segmental bridge sections were made from almost 2,000 pre-cast segments and
51 in-situ segments. Advantages of this method included a cleaner site and a faster construction time in this environmentally-sensitive area.
青衣東高架道路是連接昂船洲大橋及青衣 1 南灣隧道的主要橋樑,疏通機場與市中心 的繁忙交通,是綜合道路網絡發展計劃的 重要一環。
  聯營公司主要負責興建一條雙程三線分隔的高架
  道路,以及相關的高架引道、路面及斜坡工程、渠務
  工作、環境保護及綠化工程等。
  為加快施工進度及紓緩對附近自然環境的影響,工程
  小組以預製組件建造高架路段,並運用平衡式懸臂建造
  法將大橋的預製組件吊起,拼合成高架路段。
整項工程涉及約2,000個預製組件及51件現場生產的 組件,拼合成18段預製橋面。整套施工方法乾淨利落, 有效縮短施工期之餘,更照顧到環保的需要。
