翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Marsh Lock ： ウィキペディア英語版 Marsh Lock Marsh Lock is a lock and weir situated on the River Thames in England near Henley-on-Thames, Oxfordshire. The lock is close to the Berkshire bank, but accessed from the Oxfordshire side via two long walkways, the downstream one being near Mill Meadows. The first pound lock was built by the Thames Navigation Commission in 1773. The weir consists of a series of iron watergates running from the lock to the Oxfordshire bank near the mills. It is situated between the two walkways. ==History== The earliest record of a flash lock is in 1580, but the lock and weir existed for some time before that. The pound lock was the third downstream of the eight locks built after the navigation act of 1770, and was completed in fir wood in 1773. Humphrey Gainsborough, a non-conformist minister at Henley Congregational Church was concerned in the building of the lock. He was an inventor and the brother of the artist Thomas Gainsborough. By 1780 the lock was reported as decaying fast, and in 1787 it was rebuilt of oak. The first lock-house was built in 1813. Positioned as it was on the opposite side of the tow path, the lock was considered "Extremely inconvenient and dangerous for barges" in 1814 and there are some indications that the flash lock was still in use. In 1843 the lock was in poor condition and plans were drawn up to rebuild it on the opposite side of the river. However these came to nothing and the lower walkway was built about this time. The weir was rebuilt after 1879 but with some complaints about its unattractiveness. There were again proposals to move the lock across the river but it was rebuilt of more solid timber and reopened in 1886.〔Fred. S. Thacker ''The Thames Highway: Volume II Locks and Weirs'' 1920 - republished 1968 David & Charles〕 The lock was rebuilt again in 1914. The weir was reconstructed in 2004 by Mowlem PLC to a design by Halcrow Group. 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「Marsh Lock」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
