Report

Technical Visit to District Cooling System (DCS) at Kai Tak Development Phase III (Package A)

By Wilson Xing

A technical visit to the District Cooling System (DCS) at Kai Tak Development Phase III (Package A) – Chilled Water Pipe Laying Works had been organized by HKIE Civil Division on 12 September 2015 with 25 members participated. The visit started with a welcoming speech by Mr. T. S. Ng of EMSD. After that, Mr. Patrick Lam of Meinhardt Infrastructure and Environmental Ltd. (MIEL) gave a brief introduction of DCS in Kai Tak Area and outlined the scope of work under this contract. Then, Mr. Andy Lung of the Contractor, Wo Hing Construction Co., Ltd. (WH) demonstrated the construction sequence of TBM pipe jacking, pipeline installation and field jointing, etc.

To enable a more effective and efficient project observation, participants were divided to two groups. The Group 1 went to see the jacking pit while the other group was taken to the receiving pit and pipe storage area.

At the jacking pit, participants had a chance to see the ELS structure, TBM control room, lifting frame and slurry treatment equipment. Through a bird view from the bridge, the tunnel in the bottom could be clearly seen. Some of the participants were invited to go to the bottom and the rest visited the control room. An engineer of MIEL explained how the TBM operates, and he also illustrated how to deal with the slurry from the TBM. In addition, he explained the safety control, segment installation, and how to link up with control room.

At the receiving pit, the participants could see the receiving pit already set up for the TBM. As the TBM had finished excavating to this point, it would be lifted out and delivered to the jacking point for the start of another tunnel. The pipes storage area stored cooling mains of different kinds and sizes. The resident engineer pointed out that there could be 3 pipes at most and he used an example to demonstrate to the components including a sensor for to monitoring the pipe condition.

Throughout the visit, participants learned a lot about the tunnel work, not only in terms of the construction sequence but also about the construction techniques. On behalf of HKIE Civil Division, we would like to express our sincere gratitude to EMSD, MIEL and WH for organizing such an informative and practical activity.
