Method of constructing a retaining dam and prefabricated steel member, in particular for a retaining dam constructed according to this method

摘要

A base row BR of wall elements 6 are embedded in a trench 16 in the centre of the intended dam body 1. The wall elements 6 each consist of individual W-shaped section plates lashed to one another. The dam soil materials 3-5 are subsequently deposited laterally onto this base row BR and compacted. A first vertical row HR of section plates, if need be lashed to one another to form wall elements 7, is now bolted in an overlapping manner to the base row BR. After that, the dam soil materials 3-5 are again deposited in several layers Sch1-Sch4 on both sides of the vertical row HR and compacted. Following this, further vertical rows HR of individual section plates or of preassembled wall elements 7 are bolted one after the other in individual assembly steps up to the intended dam height, and the dam soil materials 3-5 are deposited in layers in each vertical row HR and are compacted up close to the respective top edge.
