In the second construction phase of the 99.8 million dollar project, Koh Brothers Ltd. is extending the underground canal system of this city with a population of more than 5,400,000 people. Between Bukit Timah Road and the Holland Green currently the trapezoidal wastewater canals and confluences are being enlarged, to allow up to 30 % more rainwater to flow off in a controlled manner. For this a SENNEBOGEN 683 HD is used to introduce countless sheet piles for the canal extension. The attached PTC 30 HFV vibrator hammer drives the meter-long sheet piles into a depth of 15 meters into the ground. Thanks to the telescopic crawler running gear, the 683 HD is not only extremely stable, it can also be moved quickly for this task. This crane can access to very narrow working area while working on top of a constructed metal platform over the canal. For the operator, the ergonomic Maxcab offers an ideal overview of the work area.
The extension of the canal section, which is 3.2 km in length, is part of the National Water Agency's comprehensive 750 million dollar project with the goal of being better prepared for future heavy rainfall.
