摘要： A rubber tube for dredging work embedded in and used in a pipe-line used for dredging work in the sea or river. This rubber tube has a tubular body made of rubber having a plurality of strengthening clothes embedded therein, and a plurality of metal rings axially arranged in a suitably spaced relation which are embedded in an inner peripheral surface of said tubular body and which inner peripheral surface forms a part of the inner peripheral surface of said tubular body. The metal rings have their joined surface with the tubular body placed in parallel to the axis and axial both ends thereof made thin in wall-thickness. Thereby, a contact area between the metal ring and the tubular body is increased to strengthen a bonding force and minimize a peeling off of the joined surface between both ends of the metal rings and the tubular body.

摘要翻译： 用于疏浚工作的橡胶管，嵌入并用于在海上或河流中疏浚工作的管道。 该橡胶管具有嵌入其中的多个强化衣物的橡胶制管状体，和以适当间隔的关系轴向配置的多个金属环，嵌入在所述管状体的内周面上，该内周面形成 所述管体的内周面的一部分。 金属环具有它们的接合表面，其中管状体平行于轴线放置，并且轴向两端的壁厚变薄。 由此，金属环和管状体之间的接触面积增加，以增强接合力，并使金属环和管状体的两端之间的接合表面的剥离最小化。
