  • the base element 7 has a widened base, on the longitudinal side end surface 13, ie the rear side of the base element 7, which supports the ballast bed 24 (FIG. Fig. 1 ), at least one base element projection 28 arranged, in particular integrally formed with the base element 7, is.
  • This base element projection 28 extends in the direction of the longitudinal side end face 13 of the base element 7 away.
  • the base element projection 28 projects beyond the wall element 8 in the direction of the ballast bed 24. It is thus achieved that the base element 7 passes through this at least one base element projection 28 to below the ballast bed 24 (FIG. Fig. 1 ) enough, whereby an additional fixation of the base element 7 by the weight of the ballast of the gravel bed 24, which is arranged on this base element projection 28, can be achieved.
  • the base element projection 28 can thereby extend over only a partial area or over the entire base element longitudinal extension 11 (FIG. Fig. 3 ). It is also possible that several, for example two or three, base element projections 28 are arranged or formed one behind the other in the direction of the base element longitudinal extension 11.
  • an upper side 29 of the base element projection 28 is formed inclined downwards, as is made Fig. 7 is apparent.
  • the base element projection 28 preferably connects flush to the underside 15 of the base element 7 or is a component of this bottom side 15. However, it is also possible for the base element projection 28 to be offset from the underside 15 in the direction of the height of the base element 7.
  • the underside of the base element projection 28 is formed in the plane of the underside 15 of the base element 7, the underside is preferably inclined with the inclination of the underside 15 against the horizontal. It is also preferred in this case if, on or in the underside of the base element projection 28, the at least one recess 20, in particular for drainage of the subgrade, is formed.
  • the base element projection 28 is still tapered in the front in the direction of the longitudinal side end face 13 of the base element 7 away.
  • the so - called center element of the noise protection wall as shown in FIG Fig. 5 between the two track sections is shown, corresponding to that in the AT 508 575 B1 or the DE 20 2011 052 057 U1 shown embodiments can be formed. It will do that on the AT 508 575 B1 and the DE 20 2011 052 057 U1 Referenced.
  • noise protection device 1 The above-described embodiments of the noise protection device 1 are used in particular as so-called field elements.
  • the exemplary embodiments show possible embodiments of the noise protection device 1, wherein it should be noted at this point that various combinations of the individual embodiments are possible with each other and this possibility of variation due to the teaching of technical action by objective invention in the skill of those working in this technical field.
  • parts of the noise protection device 1 or the track system 2 can form independent inventions.
  • an independent invention the arrangement of the channel 21, ie the cable tray, in the base element 7, in particular in the security room 23 be.
  • Another independent invention may be the arrangement of the noise protection device 1 in the track system 2, as they are in Fig. 1 is shown to be.
  • the above-described height compensation can represent an independent invention.
  • the noise protection device is arranged on a fixed roadway.
  • Another independent invention may be the arrangement of the base element projection 28.
