Coronation Drive Retaining Wall is a heritage-listed embankment at Coronation Drive, Brisbane City, City of Brisbane, Queensland, Australia. It was formerly known as the North Quay retaining wall. It was designed by Thomas Kirk and built from 1887 to 1887 by George E Willcocks. It was added to the Queensland Heritage Register on 21 October 1992. == History == In late January 1887 Brisbane experienced severe storms which resulted in flash flooding and damage throughout the city. A couple of weeks after the floods, sections of the river bank and road along North Quay fell into the Brisbane River. An existing embankment and "dry stone wall" had been undercut and collapsed. The Brisbane Municipal Council was advised by their Chief Engineer, Thomas Kirk, of several options for dealing with the problem. The council decided on the most permanent solution - to construct a mass concrete retaining wall at an approximate cost of £13,000.〔 Kirk's choice of concrete rather than masonry work was quite adventurous, as mass concrete technology was new to Australia. Kirk prepared the designs and the contract was awarded to George E Willcocks. Work began in May and the actual construction time was shorter than even Willcocks' optimistic estimate - the road was opened four months later. One of the most challenging tasks in the construction involved massive excavations, the deepest being for a huge coffer dam which kept the river waters out of the site. The men preparing the foundations many feet below the low tide mark worked behind this dam with the full force of the water bearing on the other side.〔 G E Willcocks had been involved in railway construction in South Africa in the early 1880s. After hearing of the Queensland government's plan to borrow £10,000,000 for an expanded railway construction programme, he migrated to Australia in 1885. In 1886 he began a long career in municipal and government works by winning a contract for building a storm water drainage system in South Brisbane and Kangaroo Point. Other public works followed - Stratton Drain, the Ann Street wall, the North Quay (now Coronation Drive) wall, extensive railway works in southern Queensland and northern New South Wales and the wood blocking of Queen and George Streets.〔 The stone cappings which were on the piers have been replaced with bricks. A section of the western end of the wall was moved in 1983.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coronation Drive retaining wall」の詳細全文を読む スポンサード リンク
