A TOTAL of 11 Liebherr excavator rigs, including seven HS 855 HD dutycycle crawler cranes, are being used by French contractor Soletanche Bachy to excavate deep trenches for the slurry wall being built as part of the Bugis interchange station at the new Downtown Mass Rapid Transit Line (DTL) in Singapore.
Predicting the effect of temperature change on heat-exchanger piles
HEAT-EXCHANGER piles, as the main example of energy geostructures, are a sustainable technology for the heating and cooling of buildings. They consist of two main components: the pile foundations of a building, which transfer construction loads to the ground; and a system of heat exchange with the ground.DTH drilling tools extend their reach
In 2002, Atlas Copco launched the Secoroc COP 64 Gold, its most productive 6in DTH hammer ever. The company followed that up in 2004 with the Secoroc COP 54 Gold, for those who wanted the same performance in a smaller tool. Now, Atlas Copco says the family is complete with the launch of its latest model – the Secoroc COP 44 Gold.Stent brings sound of silence to Deptford piling project
