摘要
The invention relates to a tubular element of a fall pipe used for the purpose of depositing materials underwater from a fall pipe vessel. The fall pipe element comprises a male and a female coupling part for coupling to another element of the same form. The coupling parts are provided on respectively an outer periphery and inner periphery thereof with an annular flange which is divided in peripheral direction into segments which leave recesses clear therebetween. For coupling purposes segments of a male coupling part are placed through recesses of a female coupling part and slid by rotation under segments of the female coupling part. The invention likewise relates to a fall pipe and a method for assembly thereof. The fall pipe is particularly suitable for depositing material at great water depth.
