一、前言皱纹管式表层取水装置(专利)如图-1所示。皱纹管是可以伸缩的结构物。一般型式的取水装置(例如圆筒型取水塔)中间部份是由可以拆动的若干段组合而成,而皱纹管式取水装置的特点是中间不需拆装即可伸缩。在实地装配的皱纹管式取水装置其皱纹部份用橡胶制成。但是,若全用橡胶做成,则由于要承受内外水压力差,皱纹管将弄瘪。为防止这种现象的发生,使用钢材作抗压环。在本模型试验中,用聚乙稀薄膜(0.1mm)替代橡胶薄壁管、用丙稀酸树脂替代钢环。当皱纹管较长调节范围较大时,则由于自重的作用,上部产生拉力,而下部产生压力,因
First, the foreword wrinkled tubular surface water device (patent) as shown in Figure -1. The wrinkle tube is a retractable structure. The middle part of the general type of water intake device (such as a cylindrical water intake tower) is composed of a plurality of sections that can be disassembled. The feature of the corrugated tube water intake device is that the middle part can be retracted without disassembly. The wrinkled tubular suction device assembled in the field is made of rubber. However, if the whole is made of rubber, the corrugated tube will deflate due to the pressure difference between inside and outside water. To prevent this from happening, steel is used as a compression ring. In this model test, a thin polyethylene film (0.1 mm) is used instead of the rubber thin-walled tube, and the acrylic resin is used instead of the steel ring. When the wrinkle tube longer adjustment range is larger, due to the role of self-weight, the upper part of the tension, and the lower part of the pressure, due to
