An Atlas Copco oil-injected rotary screw compressor is working on piling for the bridge, which will span a river in Shanghai's Pu Tuo district
Chinese contractor Shanghai Sheng Xin Construction Co is using an 161 Atlas Copco XAS 67 compressor on a new road bridge project in Shanghai. The new bridge is at Dan Ba Road, one of the main arteries in this older part of the city. The contractor is due to complete the 1km of bridge and approach roads in March of this year. The piling being used for the bridge is steel reinforced concrete as the ground here is soft and requires substantial support. After the piles are driven into the ground, a remainder remains above the surface and the bridge superstructure is mounted on top. Pneumatic hammers remove the concrete and expose the steel reinforcement, with air from the compressor then being used to blast away remaining fragments. There are around 100 piles being driven in total, with 50 on either side of the river.

    The use of high-pressure water jets to remove old concrete on structures is becoming increasingly popular Hydrodemolition of concrete structures by robotic equipment is becoming an increasingly used method for removing deteriorated concrete with high-pressure water techniques. It offers the selective removal of deteriorated concrete, while retaining sound concrete below the intended level of removal, a process that will not damage rebar or cause micro-cracks in the concrete, as will mechanical methods s

    Preserving the unspoiled Mullum Mullum Valley was the major consideration when deciding to build a traffic tunnel The answer to one of the major issues facing construction of the A$2.5 billion EastLink route in Australia was simple: construct a tunnel. While it was expensive, those involved realised they had little option but to go underground to protect the environmentally sensitive Mullum Mullum Valley, an untouched area of wood and bushland in Melbourne. EastLink, the 39km toll road project on the easter
