DE102011013145A1 - Modular pivotable sound insulation wall for use on railway lines, particularly for running tracks on country roads, railway lines or waterways, has two elements, each consisting of suspension with two joints - Google Patents

Abstract

The modular pivotable sound insulation wall has two elements, each consisting of a suspension with two joints (1) attached to the suspension. One of the joints is fixed to an anchor (3) and the other joint is fixed to a holder (4). The wall elements are positioned on the respective holder between the two elements. An independent claim is also included for a method for installing a modular pivotable sound insulation wall on a running track.

Description

Noise barriers are being built to actively reduce noise on railway lines. These are the more efficient the closer they are to the track and can therefore be built lower. The control clearance profile specifies the minimum required width for train movements. On some routes, over-wide trains are allowed as standard, in some cases other clearance profiles apply.

Noise barriers should therefore be installed as close to the gauge as possible and, at a height of only about 1 m, offer sound protection similar to that of the widely used conventional high noise barriers (or noise barriers) made of a variety of materials, up to 6 m high to reach.

However, the previous design of low noise barriers obstructs construction work on the track, because track laying machines in use are much wider than the regular clearance gauge and also interfere with fixed installations in the field of gravel in the regularly required processing of the ballast bed or the substrate.

Especially in urban areas, low noise barriers offer not only better sound absorption efficiency, but above all urban design advantages, since the location is not cut through in addition to the railway line by up to 6 m high noise barriers.

A low noise barrier, which can be removed from the nearer track area if required, has so far been missing.

The flaps of the noise barrier upwards, such. In the patent DE 10 2008 002 836 A1 described, requires a tremendous effort especially for longer mounted sections of the noise barrier, which are fold up together.

Invention:

The principle of the pivotable noise barrier ( 1 and 2 ) consists in the suspension with two joints ( 1 ) through which the arms of the suspension ( 2 ), the wall elements ( 5 ) and anchoring in the ground ( 3 ) forms a movable parallelogram, so that the noise protection wall is to pivot laterally out of the track area ( 2 ). The sound-absorbing wall elements ( 5 ) are placed in a holder ( 4 ) attached as required by all different types of wall elements. For example ( 2 ) aluminum elements are inserted from above into an I-profile.

Removable stiffeners ( 7 ) prevent unwanted swinging of the wall by the air blast and suction of passing trains and a possible rattling.

By a separation of the continuous wall ( 2 ), z. B. by lifting out a portion of the wall elements ( 5 ) create manageable sections that are pivoted individually (in sections) ( 6 ).

For this purpose, individual or all sections of the noise barrier are made removable ( 6 ). For example, between the brackets ( 4 ) a flat tension element ( 8th ) absorb the tensile force. The wall elements ( 5 ) are inserted over it and secured only against a lift up. In non-removable sections, the tensile force can also be absorbed directly by the wall elements.

With the new version of the suspension can be mounted with appropriate version of the mounting options all types of common noise protection elements. The separation of the individual auszuschwenkenden sections before pivoting ( 6 ) can be done, for example, by removing a section ( 5 ) or by releasing the compound ( 10 ) between two sections ( 6 ).

in an alternative embodiment, the anchoring in the ground is rotatable in itself, so that the joint on the support of the anchoring can be dispensed with ( 3 and 4 ). The anchoring becomes rotatable ( 8th ) and in the foundation with recording ( 9 ) for anchoring.

The further anchoring of the foundation in the ground must be carried out according to local requirements.
