LIIKENNEMELUNVAIMENNUSMENETELMÄ JA -LAITETRAFFIC NOISE METHOD AND DEVICE

Patenttivaatimuksen mukainen menetelmä liikennemelun vaimentamiseksi, jossa 5 liikennemelunvaimennuslaite kiinnittyy pääosin olemassa oleviin turvarakenteisiin, kuten ajoväylän turvakaiteisiin ja maan- sekä rautateiden siltakaiteisiin ja moottoriratojen turvakaiteisiin, jolloin liikennemelun vaimennuslaite sijoittuu mahdollisimman lähelle melulähdettä hyödyntäen jo aiempia investointeja tehokkaasti.The method of attenuating traffic noise of claim 5, wherein the traffic noise reduction device is mainly attached to existing safety structures, such as carriageway and railroad bridge and motorway safety railings, whereby the traffic noise reduction device is located as close as possible to the noise source.

Aiempien liikennemeluntorjuntaratkaisujen heikkoutena on pääosin niiden hankala sijoittaminen kauaksi melulähteestä, jolloin rakenteista tulee huomattavan korkeita ja siten ne toimivat näkemäesteenä rajaten melulta suojattavat alueet toisistaan erillään oleviksi osiksi. Perinteiset korkeat meluvallit ovat rakennus- ja huoltokustannuksiltaan huomattavan kalliita ja niiden meluntojuntavaikutus äänen heijastumisen takia on 15 toisinaan epätoivottua, eivätkä ne sovellu lainkaan esimerkiksi maantie-ja rautatiesiltojen meluntorjuntaan.The disadvantage of previous traffic noise control solutions is mainly their difficulty in locating them far from the noise source, whereby the structures become remarkably tall and thus act as a visual barrier, separating the areas protected from noise into separate parts. Conventional high noise barriers are very expensive in terms of construction and maintenance, and their noise reduction effect due to sound reflection is sometimes undesirable, and they are not suitable at all for noise abatement in road and rail bridges, for example.

Piirroksessa vaimennuselementti (la) on ikään kuin esitetty läpinäkyvänä ja sen takaa näkyvät vaakapalkki (5) ja 5 pystytolppa (4).Figure 3 shows the attachment of a noise reduction device according to the invention to a conventional road rail, parallel to the road. In the drawing, the damping element (1a) is as shown transparent and has a horizontal bar (5) and 5 vertical posts (4) behind it.

Kuviossa 4 on myös esitetty keksinnönmukaisen melunvaimennuslaitteen kiinnitys tavanomaiseen maantien kaiteeseen, tien suuntaisena.

Here, the damper (1) is attached directly to the horizontal bar (5) of the handrail by its fastening means (2).

Vaimennuselementin (la) ominaisuuksista riippuen sitä voidaan tarvittaessa jäykistää pystysuunnassa joko levymäisellä tai palkkimaisella rakenteella (ei kuvattu). Tarvittaessa liikenneväylän turvarakenteen puuttuessa voidaan liikennemelunvaimennuslaite (1) asentaa erilliselle telineelle (ei kuvattu) väylän välittömään läheisyyteen.

Depending on the properties of the damping element (la), it can be stiffened vertically by either a plate-like or a beam-like structure (not shown), if necessary. If necessary, in the absence of a roadway safety structure, the traffic noise cancellation device (1) can be mounted on a separate rack (not shown) in the immediate vicinity of the roadway. The structural movement of the damping device (1), which consists of separate damping elements (la), integrates V * 20 into the possible unevenness of the anchorage so that the anchorage: · needs to be leveled separately, while allowing unhindered road maintenance.
