    Sample text

    The pH and iron levels were also unsuitable for direct surface discharge, so that treatment was essential. 0 by injection of a caustic soda (NaOH) solution. At the elevated pH the iron began to precipitate out of the solution. 5 using hydrochloric acid (HCl). This halted the process of iron precipitation and also reacted with the caustic soda to form common salt (NaCl). At this stage the iron had come out of the solution and was a suspended solid. The processed groundwater was then pumped to a series of settlement ponds where the iron floc was allowed to settle out.

    The probes, electrodes and negative connections terminated at junction boxes for monitoring using special equipment for corrosion rate monitoring and reference electrodes potential. DEWATERING SYSTEM The dewatering system for the tunnel works consisted of dewatering wells, a chemical treatment system, settling ponds and recharge wells. The system was required to allow construction of the tunnel, which at its deepest was more than 10 m below sea level and at its closest point was only 60 m from the Cobaki estuary system.

    Within the bored tunnels, the rails are between about 9 and 21 m below ground surface. 5 km. 16 m internal diameter bored tunnels have a 275 mm thick segmental lining. • Foreshore cut-and-cover tunnel, open box structure and dive structure, extending from the southern end of the Esplanade Station until the rail track rises to ground surface between the two carriageways of the existing Kwinana Freeway. These structures were nearly all formed of in situ concrete within temporary retaining walls. FIG 2 - City Project tunnel route options considered in 2001/2002.
