Description
Изобретение относитс к строительству , а именно к композици м дл изготовлени балластного сло железнодорожного пути.The invention relates to the construction, in particular to compositions for the manufacture of a ballast layer of a railway track.
Цель изобретени - улучшение вибрационных характеристик.The purpose of the invention is to improve the vibration characteristics.
Композици дл изготовлени балластного сло железнодорожного пути включает легкий наполнитель, наприме керамзит объемной, массой 600 кг/м , аглопорит марки 700 или шлаковую пемзу марки 800, св зующее та виде вспенивающегос полиуретана марки ППУ-3 или 1ШУг315-1 и стекловолокно с длиной волокна 50-100 мм при еле- дующем соотношении компонентов, мас.%:The composition for the manufacture of a railway ballast layer includes a lightweight filler, for example, expanded clay with a bulk weight of 600 kg / m, agloporite grade 700 or slag pumice grade 800, connecting this form of foamed polyurethane grade PPU-3 or 1ShUg315-1 and fiber glass with a fiber length of 50 -100 mm with a lower ratio of components, wt.%:

Составы предлагаемой композиции приведены в табл. 1, а их свойства - ,в табл. 2.The compositions of the proposed composition are given in table. 1, and their properties - in table. 2
Компоненты композиции в балластном слое укладьгоаютс послойно: легкий наполнитель, стекловолокно и т.д. После заполнени объема все запиваетс вспенивающимс полиуретаном.The components of the composition in the ballast layer are arranged in layers: lightweight filler, fiberglass, etc. After filling the volume, everything is washed down with foaming polyurethane.
При воздействии циклических колебаний , стекловолокно вибрирует. Однако его колебайи отличаютс по фазе от колебаний полимера. В результате этого происходит рассеивание энергии трени , возникающей от движени гибких цепей, наход щихс вблизи жестких . Уровень поглощени механической энергии за счет наличи жесткого материала увеличиваетс , что ведет к повьш1ению виброгас щих свойств.When exposed to cyclical vibrations, the glass fiber vibrates. However, its vibrations differ in phase from the vibrations of the polymer. As a result, the energy of friction arising from the movement of flexible chains near rigid chains is dissipated. The level of absorption of mechanical energy due to the presence of hard material increases, which leads to an increase in vibration damping properties.
