Cave-ins hit bridge building as drink-water pipe bursts

Top News | Charlotte Luo 26 Feb 2019

Two cave-ins occurred in the Hong Kong Port passenger clearance building of the Hong Kong-Zhuhai-Macau Bridge yesterday. Both are said to have been caused by land subsidence.

Passengers spotted the cave-ins after midnight yesterday.

The Water Supplies Department cordoned off the cave-ins with railings. It said it received notification from the Highways Department at around 2pm that a pipeline burst near the Hong Kong Port building.

It said it then sent staff, who found a 30-centimeter pipe for drinking water burst. They completed repairs at 3pm.

One subsidence site measured three by four meters, with a depth of about two meters.

The other was about two by three meters and about 30 centimeters deep. Some bricks fell into the holes while silt and underground pipelines were exposed. Workers filled the hole with silt and replaced the bricks.

The two spots were 30 to 40 meters apart.

A worker said the damaged pipeline could have been caused by subsidence of the artificial island on which the passenger clearance building stands.

A resident said he saw the two cave-ins at about 3am. He said the spots were on the way to the entrance of the building, where passengers and people working in the Hong Kong Port have to pass through.

"The ground is uneven. Other places may sink as well. If people suddenly fall into such a hole, they can be easily hurt," he said.

He found the incident worrying because the subsidence occurred so soon after completion of the Hong Kong Port. Another resident questioned why such a large construction project was of such bad quality. The 55-kilometer bridge was opened to the public on October 24 last year.

Hong Kong Port is on reclaimed land of about 130 hectares northeast of the airport.

By means of the transport network - including the Hong Kong Link Road and the Tuen Mun-Chek Lap Kok Link - people can travel to the main bridge, the airport, Tuen Mun and North Lantau through the Hong Kong Port.

Meanwhile, cross-border shuttle bus operator HZM Bus said it has provided more than 170,000 shuttle bus services for more than six million passengers so far.

Chairman Zhang Guangyou said 162 buses are in service, including traditional buses and double-deckers.
