Abstract

All types of wooden sub-rail base for the Belarusian railway are manufactured by Borisov sleeper impregnation Plant and are made in the form of sleepers, transfer bars, bridge bars, etc. The analysis of the production process showed the presence of the remaining bars with a length of less than 2.75, which cannot be used for the manufacture of sleepers. Similar residues with a length of 0.25 to 0.50 m are obtained after sawing out of a 5.50 m long saw log of transfer bars, the length of which varies from 2.75 to 5.50 m in increments of 0.25 m. The purpose of this work is to assess the prospects for the use of wooden beams of various lengths remaining after sawing the transfer bars, for the development of a resource-saving technology for the manufacture of composite sleepers, characterized by a decrease in material and energy consumption of products. It is shown that one of the options for the rational use of residues can be the manufacture of composite sleepers from two or three parts interconnected in various ways, on which the reliable operation of the structure depends, and the need to introduce additional technologies, for example, for the manufacture of bolts, screws, etc. A resource-saving technological scheme for the manufacture of composite sleepers is proposed, which allows reducing unproductive expenses of the enterprise and raw materials – business wood.
