Abstract

Mata tłumiąca stosowana w konstrukcji dróg kolejowych, w celu redukcji dynamicznych oddziaływań na otoczenie w postaci drgań, pochodzących od ruchu pojazdów szynowych, zaopatrzona w warstwę nieprzepuszczalną wypełnioną materiałem niezwiązanym na bazie wypełniaczy polimerowych, charakteryzuje się tym, że składa się z zabezpieczającej warstwy zewnętrznej - spodniej (2.1) i wierzchniej (2.2), zamkniętej warstwy wewnętrznej, umieszczonej pomiędzy warstwami zewnętrznymi oraz luźnego materiału wypełniającego (4) warstwę wewnętrzną, przy czym warstwa wewnętrzna jest zaopatrzona w co najmniej jeden otwór odpowietrzający; przy czym wewnętrzna warstwa jest podzielona na komórki, przez przegrody, które to komórki mogą być połączone ze sobą kanalikami ciśnieniowymi; przy czym warstwy zewnętrzne, spodnia (2.1) i wierzchnia (2.2) mogą być ze sobą połączone za pomocą znanych ze stanu techniki łączników.A damping mat used in the construction of railway roads to reduce dynamic impacts on the environment in the form of vibrations resulting from the movement of rail vehicles, equipped with an impermeable layer filled with unbound material based on polymer fillers, characterized by the fact that it consists of a protective outer layer - bottom layer (2.1) and the top (2.2), a closed inner layer placed between the outer layers and a loose material (4) filling the inner layer, the inner layer being provided with at least one vent hole; the inner layer being divided into cells by partitions, which cells may be connected to each other by pressure channels; the outer, bottom (2.1) and top (2.2) layers can be connected to each other using connectors known from the state of the art.
