DETAILED DESCRIPTION

[0043] The more general and advantageous configurations of the present invention are described in the Summary of the invention. Such configurations are detailed below in accordance with other advantageous and/or preferred embodiments of implementation of the present invention.

[0044] In a preferred embodiment of the double-sided noise barrier of the present invention, it comprises a support structure formed by two side surfaces provided with a plurality of sound insulating plates. At least one sound insulating plate is mounted in each side surface of the support structure, forming a sound absorbing space ahead of each. In a particular embodiment of the double-sided noise barrier, the sound insulating plates cover the entire side surface of the support structure. In another embodiment, a sound insulating plate comprises an insulation material, preferably consisting of a noise absorbing material. Yet in another embodiment, said insulator material comprises, preferably consists of, a steel or aluminium casing with perforated surface and a noise absorbing interior made from a noise absorbing material. In another embodiment, the double-sided noise barrier comprises a steel sheet cover.

[0045] The use of a double-sided noise barrier provides a 360° soundproofing space around it, which is of utmost importance in the design of GRE structures aiming to achieve space optimization.

[0046] In connection to it, the present invention also describes a GRE comprised by at least one double-sided noise barrier and by one jet blast deflector. In a preferred embodiment of such GRE, combinable with any above embodiments of the double-sided noise barrier herein described, it comprises one back barrier and at least one lateral barrier. Each of the at least one lateral barrier extends in a direction and is arranged in such a way in relation to one of the ends of the back barrier, forming an angle of at least 90°.

[0047] At least one of the barriers, i.e. lateral barriers and back barriers, is a double-sided noise barrier. In the context of the present invention, a lateral and a back barrier which is formed by a double-sided noise barrier is defined as a lateral double-sided noise barrier and as a back double-sided noise barrier respectively. Also, in the context of the present invention, a back barrier or a lateral barrier is a single-sided noise barrier, therefore, only able to provide a 180° soundproofing space. Accordingly, a back or a lateral barrier is a support structure which comprises sound insulating plates in only one side surface of such structure. Said sound insulating plate comprises an insulator material, and preferably are consisted of a noise absorbing material. In one embodiment, the insulator material of a barrier comprises, preferably consists of, a steel or aluminium casing with a perforated surface and a noise absorbing interior made from a noise absorbing material.

[0048] In a preferred embodiment of the GRE, it is comprised by one lateral double-sided noise barrier, one lateral barrier and one back barrier. In an alternative embodiment, the GRE is comprised by two lateral barriers and one back double-sided noise barrier. In another alternative embodiment, the GRE comprises two lateral double-sided noise barriers and one back double-sided noise barrier. The angle formed between lateral barriers or lateral double-sided noise barriers and a back barrier or a back double-sided noise barrier are equal, and the angle between a lateral and a back barrier, of a single or double-sided type, is within the range of from 95 to 130°.

[0049] In what concerns to the jet blast deflector, it is structurally disposed in the space immediately in front of a back barrier or of a back double-sided noise barrier. By immediately in front, it is to be understood that there is a minimum configurable space between the deflector and the barrier.

[0050] Respecting the main objective of the present invention, related to maximizing the number of GREs and optimizing the space occupied by each structure, it is disclosed a plurality of GRE structures, which are comprised by at least one GRE composed by at least on double-sided noise barrier. By means of the technical advantageous provided with the use of a double-sided noise barrier, which offers a 360° soundproofing space around its support structure, it is possible to develop GRE structures that enable optimization of space in the assembly of a set of individual GREs.

[0051] In this regard, in a preferred embodiment, the GRE structure is comprised by at least one GRE. Particularly, a free end of at least one lateral double-sided noise barrier of a GRE is associated with, preferably connected to, an end of a new back barrier or of a new back double-sided noise barrier. Alternatively, at least an end or at least a free end of a new back double-sided noise barrier of a GRE is associated with, preferably connected to, an end of a new lateral barrier. In this context, an additional jet blast deflector can be structurally disposed in the space immediately in front of a new back barrier or in front of at least one of the sides of a new back double-sided noise barrier.

[0052] In another preferred embodiment, it is proposed a concatenated GRE structure comprised by at least two GREs, wherein the concatenated assembly of GREs is performed by associating, preferably connecting, a free end of a lateral double-sided noise barrier of a GRE with an end or with a free end of a back barrier or of a back double-sided noise barrier of another GRE.

In that way, and contrary to the embodiments referred above, the additional blast deflectors are not associated to any single or double-sided back barriers, being positioned in such a way to take advantage of the 180° soundproofing space provided by each lateral double-sided noise barrier of the GRE and not having any back barrier—single or double-sided—behind it.

[0054] As will be clear to one skilled in the art, the present invention should not be limited to the embodiments described herein, and a number of changes are possible which remain within the scope of the present invention.

[0055] Of course, the preferred embodiments shown above are combinable, in the different possible forms, being herein avoided the repetition all such combinations.
