In the civil engineering field of construction or maintenance of infrastructure, trenches are created to install underground infrastructure or utilities (such as gas mains, water mains or telephone lines), or later to search for these installations. Trenches have often been dug for military defensive purposes. In archaeology, the "trench method" is used for searching and excavating ancient ruins or to dig into strata of sedimented material. == Types and uses == 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「Trench」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.
