Definitions

  • the invention relates to a protective device for arrangement on a traffic route comprising at least one wall element, a wall element for a protective device for installation on a traffic route, comprising at least one surface element, a protective wall system comprising a plurality of protective devices with wall elements, as well as the use of the protective device or the wall element.
  • Protective devices in the form of wall elements are constructed on or on traffic routes for different reasons. On the one hand, these protections are used to protect against noise, on the other hand, roadways can be separated from each other, for example in a construction site area, or these protective devices are also used to better protect working areas on traffic routes from passing traffic. Usually, especially in the field of noise barriers, these protective devices are fixedly placed on or next to the traffic route and for this purpose a corresponding foundation is made, on or in which the stands for the noise barriers themselves, normally as I- or H- Beams made of steel are anchored. In addition, there are also mobile protective wall systems, especially for construction areas or on highways to separate the two directions of traffic from each other. These latter guards are usually made of concrete and are either concreted directly on site or connected to the ground.
  • guard rails are known from the prior art further, which are constructed laterally next to roads. It should be prevented so that vehicles are thrown in accidents from the road.
  • These rails can also be stirred with a so-called underrun protection to prevent slipping under the guardrail itself, for example, by motorcyclists.
  • These rails are anchored to the ground, namely, in which the stands on which the guide rails are mounted, are driven into the ground. Thus, these protections are mounted stationarily stable.
  • Object of the present invention is to provide an improved protection device for traffic routes.
  • the wall element is arranged on at least one base element that is structurally arranged on or adjacent to the traffic route, further by the aforementioned wall element, wherein the surface element at least partly consists of a rubber granulate, as well as by the protective wall system, in which the protective devices or the wall elements are formed according to the invention, and further by the use of the protective device according to the invention and the invention Ben-wall element to reduce the noise level of moving rail vehicles or as a boundary wall on roads.
  • the foundation-less design of the protective device wherein it is advantageous that the wall element and the base element are designed separately, so that on the one hand the construction and dismantling of this protection device is simplified, namely an orientation of the protection device itself easier by the base elements can take place, which may in particular also have a lower weight compared to conventional concrete partitions, and only when this alignment is done, the wall elements are arranged on the base element.
  • the storage of such protection devices is simplified, namely, since they can be made less bulky and thus have improved stackability, especially if the wall elements are designed flat, ie in comparison to down widening protections, as these from the prior Technics are known to require less space in storage.

In addition, because of the lack of foundation also the ballast cleaning easier. Due to the at least partial embodiment of the wall element with a rubber granules, that is, the surface element of the wall element, the advantage is achieved that this compared to solid concrete walls may have a lower weight.

  • the pivotability is limited essentially only by the wall thickness of the wall elements.
  • the base element can be formed by a flat concrete base.
  • the flat concrete base has the advantage that thus a surface pressure is exerted on the underlying ballast of the ballast bed. It has been shown that the underlying gravel grains are subject to less wear, so that therefore the ballast bed must be replaced less frequently in this area. In particular, so that the abrasion and the fine grain content of the ballast bed can be reduced over a longer period.

It can thus also a predeterminable distance to the source of noise generation in the region of the rails during the passage of a train and thus an at least approximately constant noise protection behavior of the protective device can be achieved by namely the lateral distance is kept substantially constant, so that this protection device optionally with a lower height of the wall elements can be performed.
