The present invention relates to a 16Mn steel sheet waterproofing dam, which comprises a water retaining steel plate, a back plugging plate, a tension bar and earth. The tension bar includes an upper and a lower tension bar. The water retaining steel plate and a back plugging plate are obliquely erected on the flood control embankment, respectively. A plurality of upper and lower tension bars are used to support the water retaining steel plate and the back plugging plate, and the shape of the upper tension bar, the lower tension bar, the water retaining steel plate and the back plugging plate is intercepted. The surface is trapezoidal with narrow upper and wide lower; the height of the water-retaining steel plate is higher than that of the back-blocking plate, and the space between the water-retaining steel plate and the back-blocking plate is filled with earth. The steel sheet waterproof dam can choose different thickness steel sheet, different lap angle and different height according to different requirements. It is free and flexible, simple in structure, easy to assemble, stable and durable.
【技术实现步骤摘要】
一种16Mn钢板防水坝
本专利技术涉及水利工程中的防水大坝,尤其涉及一种16Mn钢板防水坝。
技术介绍
防水坝是防水拦水的建筑物和构筑物,有土坝、重力坝和混凝土面板堆石坝等多种类型。人们使用的水坝主要为两大类:土石坝和混凝土坝。大坝的高度取决于枢纽地形和地质条件等指标。多年以来,每到汛期,洪水年年防,做不到长治久安,都要浪费大量的人力物力加紧修筑堤坝,以防水患。近年来,防水坝大多采用高科技的钢筋水泥建筑,人们对于其他形式结构的防水坝使用的不多。16Mn(锰)钢一般含碳量为0.1%-0.25%,加入主要合金元素锰(Mn)、硅(Si)、钒(V)、铌(Nb)和钛(Ti)等。16Mn钢的合金含量较少,焊接性良好,焊前一般不必预热。
