Аннотация: в статье предложена конструкция сплоточной единицы с повышенной волноустойчивостью для транспортировки по рекам с малыми глубинами. Представлена конструкция сплоточной единицы для предотвращения водопоглощения круглыми лесоматериалами ограниченной плавучести.
Abstract: the article introduces an advanced design of a rafting unit featuring increased wave resistance for transportation along shallow rivers. A rafting unit design providing water uptake reducing of low buoyant round wood is presented.
Ключевые слова: сплоточная единица, круглые лесоматериалы.
Keywords: rafting unit, round wood.
A special rafting unit (figure 1) for shallow rivers was developed. It consists of logs 1, laid in a row and attached by ropes 2 in pairs to two fixing logs 3 which are laid crosswise on the basic log row. The log bundles 4 are supplied with bindings 5 and are laid parallel to fixing logs. The bundles 4 are tied to the row by the mean of banding ropes 6 placed above the bundles under their bindings and below them – under bundles and fixing logs.
