Landslide Preventive Works for slope along Clear Water Bay Road

The project involved a number of slope stabilisation works along Clear Water Bay Road.

Environmental Concern

The site was immediately next to Clear Water Bay Road. Since the project involved the drilling of a large number of holes on the slope, the potential dust nuisance was the major concern.

Location of slope stabilization

Dust from slope stabilization activities affect passers-by

Dust Cover and Watering - A mobile drilling machine was being used to drill holes on the slope. To prevent dust emission during the drilling operation, the top of the machine was totally enclosed and water spray was applied to prevent dust from escaping out of the working area.

The drill was covered up and provided with water spray inside while drilling on the slope took place.

Observations & Achievements

The arrangement of enclosing the working part of the drilling machine together with the provision of water spray to control dust generation was found to be very effective.
