摘要：

Australian pipe-bursting specialist Collex NoDig replaced nearly 800 m of old water mains to upgrade water services in Sydney's suburbs. Polyethylene pipe replaced cast-iron pipe, dating back to 1897, using Grundoburst 800G pipe-bursting equipment from Tracto-Technik GmbH of Germany for water supply system in Australia. The Grundoburst 800G can deliver 380 kN of thrust and 770 kN of pullback, and is suitable for pipes from 80 mm to 450 mm in diameter. Bursting speeds of 100 m per hour can be achieved, depending on pipe material and soil conditions.
