Description
Technical field
The present invention relates to a kind of acoustics screening arrangement that is used to suppress to bother the noise that noise, especially this traffic, track traffic etc. by road cause.The invention particularly relates to a kind of acoustics screening arrangement, this acoustics screening arrangement is configured to comprise preferably by concrete framework of processing and the module that is arranged on the noise absorption box on this framework.Can a plurality of module adjoining lands be placed to a row, to produce integrated acoustics screening arrangement or barrier.
Background technology
Become the problem that increases day by day from the traffic noise of highway and railway in current society, and especially for the local resident, ambient influnence normally obviously and bother very much.Therefore, public and authoritative sources require to make effective measures.The high noise level that needs inhibition effectively to bother, and the current multiple technologies of having used.For example, excavated material is used to build the noise suppression roadbed, and wooden or concrete structure are used for bothering noise along highway and railway shielding to a great extent.Yet these measures provide limited noise protection.Noise-measuring shows with calculating, if the acoustics screening arrangement is provided with noise absorbing material on the opposite towards this part of the shielding part of noise source, then this acoustics screening arrangement is more efficiently.This effective noise absorbing material is made up of mineral wool etc., as selection, be made up of the foamed plastics that has intercommunicating pore, but these materials is inappropriate for outdoor and in the adverse circumstances along highway and railway, using.Certainly, except suppressing to bother the noise, this structure also must be able to be resisted atmospheric corrosion, is cleaned and under different climate, worked.
Thus, the technology of bothering noise that is used to suppress from highway and railway is a previously known, and still receives patent protection in some cases.
For example, SE513102 has described and a kind ofly has been used to produce by the noise absorption of for example processing from the rubber scrap of tire and/or the method for vibration suppression unit, should mix by chopping and with adhesive from rubber scrap of tire.This unit can be used as noise isolation spare at highway or railway next door, before material solidification, retainer element/lift elements is embedded in this material.These unit do not solve all be provided with stable and the effective problem that is associated of acoustics screening arrangement with rational cost along highway and railway.
WO2005033412 has described a kind of acoustics screening arrangement that comprises concrete frame, on a side of this concrete frame, grid is casted in this concrete.This grid and noise suppression material are integrally formed.Except other factors, the shortcoming of utilizing this structure is that this noise absorber can't be changed when impaired.In addition, the inhibition ability of this acoustics screening arrangement receives the restriction of the structure construction of absorber.The width of concrete profile also makes this acoustics screening arrangement be difficult to be placed with and fully approaches noise source.
FR2683368 described a kind of be used to suppress such as by road, the acoustics screening arrangement of bothering noise the noise that causes of traffic on the railway etc., this acoustics screening arrangement comprises preferably the framework processed by concrete and is arranged on the noise absorber on this framework.This noise absorber is described as replaceably and is arranged on the framework.Spacer element is arranged on the back of noise absorber, makes the certain air gap of formation between noise absorber and framework.This air gap can still be generally 20mm at 10mm between the 50mm.Noise absorber nestles up this concrete element assembling on smooth basically surface.It is smooth basically that the front surface/external surface of noise absorber is configured to, against the anterior limiting surface of concrete element.Noise absorber by be described as basically by coalescence have such as cement comprise cement, silicate or the mixture of the mineral binder of similar known substance the wood particle of adhesive process, and comprise anterior corrugated part and par, rear portion.Rely on the structure that has undulatory front side of noise absorber, this noise absorber is intended to absorb noise, but is not intended to let noise or air pass the air gap that arrives the plate back specially.Because the character of the material that is combined, control or the flow resistance of regulating through plate are impossible.In addition, it equally almost is impossible that any air that passes plate flows, and therefore this will not serve as noise absorber.The fact that plate comprises wood fibre mean it be resist atmospheric corrosion hardly and be not suitable for outdoor use thus.In addition, because lignocellulosic material is so hard and except other factors, comprises cement that it is heavy relatively therefore it being handled.Noise absorber also be described as be at mechanical aspects be rapid wear and under the help of the screw that passes noise absorbing material, assemble.This device does is integrated with any air gap and forms device in box, this device does not form a plurality of air chambers of sealing basically yet in air gap.
Therefore, the prior art in this area does not solve the problem that suppresses to bother traffic noise with flexible and effective and efficient manner and with rational cost.

The specific embodiment
Fig. 1 has illustrated in the vertical section and has been used to shield and for example absorbs the innovative acoustics screening arrangement 1 that is modular form of bothering noise from highway communication, track traffic etc.The invention particularly relates to a kind of acoustics screening arrangement 1, this acoustics screening arrangement 1 comprises preferably by fibre reinforced concrete framework of processing 2 and the noise absorber 3 on this framework 2 that is installed in that is box-like.This module is designed such that and can a plurality of unit adjoining land be placed to a row to produce integrated acoustics screening arrangement.Fabric reinforcement preferably is made up of the synthetic plastic fiber, and to avoid in framework 2, having conductive material, it is unnecessary that the measure that is used for the electrical grounding of module thus becomes, thereby can omit them.Thus, eliminated maintenance factor in the future, this is just ground connection to be carried out examination and maintenance at regular intervals because otherwise can need.
Box 3 also is made up of complete non electrically conductive material.Under the help of the rifle nail of for example insulating, box 3 is assemblied in the front side of framework 2, that is, and being intended to of module towards bothering this side that noise source points to.
In sectional drawing, watch, acoustics screening arrangement 1 has been configured base portion 4, centre portion 5 and top section 6.Base portion 4 or ground supporting portion constitute compact and heavy part, although and exist for example from the train of process or the powerful fitful wind of vehicle, this base portion 4 or ground supporting portion are intended to its acoustics screening arrangement 1 is remained in the appropriate location.In case can be with much the same big through power that caused with regard to the suction that produces, in the fitful wind that track gets into by train by the power in the pressure fitful wind that cause, when from track, coming out of the front of train generation.Therefore, module 1 is heavy and highly stable, so that from its position, does not remove by force through out-of-date at train.Just in case this acoustics screening arrangement 1 moves, this will produce serious accident risk.Train must can be with the speed process up to 250km/h, and this acoustics screening arrangement 1 also must be able to stand multiple weather phenomenon and under all weather conditions that can expect, all be stable, for example resists hurricane.In order to obtain maximum stable property, the center of gravity of framework 2 should be as far as possible near its geometric center.
Centre portion 5 is positioned on the leading edge 7 of base portion 4 or near the leading edge 7 of this base portion 4, thereby makes box 3 can be arranged to as far as possible near noise source.Preferably assembling box 3 under the help of insulated bolt still can also assemble box 3 certainly in a different manner.Because the front side of acoustics screening arrangement 1 is smooth basically and do not have this fact of any projection, compare more easily with the acoustics screening arrangement of previously known module is placed in the appropriate location.Thus, the front side of noise absorption box 3 be configured to the leading edge 7 of base portion 4 basically in line and with the leading edge 8 of top section 6 basically in line.This means that module requires ground less space, when being placed on this module on the railway bed, this is favourable.
In the upper surface of base portion 4, in the back of centre portion 5, the attached accessory 9 that is used for handle etc. can be placed on and be the for example recess of this attached accessory setting of loop bar anchor and so on.
For example, can arrange this acoustics screening arrangement 1, after assembling, this quoit removed from module by means of two hoist cables that are hooked in the quoit that is screwed onto on the module.Therefore, need not to use special lifting appliance to come operational module, this means that whole abilities of hoisting mechanism are not reduced by the weight of for example handle.
Fig. 2 a is from front surface and show noise absorption box 3 in more detail.The outside framework 11 that this box 3 is processed by for example plastics constitutes.In the front side of box 3, promptly after assembling leans against on the framework 2 of acoustics screening arrangement 1, face on that side of noise source, be provided with grid or the grid 12 (referring to Fig. 2 b) equally preferably processed by plastic material.In grid 12 or lean against on this grid 12, suitably be provided with the noise absorbing material such as elastomeric material.In order to reinforce this grid 12, can noise absorbing material for example be integrated or be casted in this grid 12 with grid 12, or as selecting bonding or otherwise put on grid 12, this in addition can use thin pad 13.If it is enough firm filling up 13, then can its loosely be placed on the back of grid 12.Box 3 is assembled on the front side of centre portion 5 of framework, and for example it avoids the influence of rainwater in the protection of place, top through the protuberance (referring to Fig. 1) on the top section 6 of framework 2.
Fig. 3 shows along the cross section of passing innovative box 3 of the line A-A shown in Fig. 2.In framework 11, the noise absorbing material and the air gap that be provided with grid 12, are 13 forms of filling up form device 14.
Noise absorbing material in the pad 13 is made up of the fine granular of for example reusable rubber at least in part, and the fine granular of this reusable rubber keeps together through the adhesive that is used for this purpose.This adhesive can be even after sclerosis, also make pad 13 is flexible and flexible bi-component polyurethane ester gum.Because pad 13 comprises little intercommunicating pore or this fact of passage, therefore, pad 13 can at least partly be breathed freely, so that flow resistance produces in pad 13.The material of pad in 13 still is durable and stands for example to wash and can not influence or weaken the noise absorption effect.Granular size influences flow resistance and can be suitable for different application with degree of compaction.Under situation about suppressing from the traffic noise of railway, using size is the particle of about 3mm, and to fill up 13 density be about 650kg/m
3Thick at pad is that its weight is about 6.5kg/m under the situation of about 10mm
2
Be sized at width under the situation of about 40mm, form the air gap 15 of width for about 30mm in pad 13 back with framework 11, promptly fill up 13 and the concrete frame 2 of module between distance be about 30mm.In this, form the width that device 14 is realized these air gaps 15 through the air gap of for example processing by plastic material, this air gap forms device 14 and forms compartments or compartment 16 and make this absorber obtain the characteristic of " local reaction absorber ".The size of the width of air gap 15 and compartment 16 is conclusive for the frequency range that will absorb noise the most effectively.Width that can be through changing framework 11 and air gap form the width of device 14 or otherwise are arranged on the centre portion 5 of concrete frame 2 and change and adjust the width of air gap 15 in a distance apart through filling up 13.In addition, the width of the air flow resistance of noise absorption pad 13 combination air gap 15 is conclusive for total noise absorption effect.Flow resistance in the noise absorbing material combines air gap to form acoustics equivalent circuit, so-called RC circuit.
Thus; Compare with the system of previously known; Absorber or box 3 have better scalable and adjustable noise absorption ability, and the most important thing is, its blanketing frequency scope; This frequency range can more easily be suitable for bothering the characteristic of noise than previous system, thereby is the reduction of unit acquisition maximum with dB (A).Just in case this acoustic absorption device/box 3 is damaged with arbitrary mode, be easy to equally replace it with new box 3.For example, the alternative of previously known requires to change whole concrete block.
Fig. 4 shows pad 13 and the rear side that is placed on the air gap formation device 14 on this pad 13, and this rear side is configured a plurality of circular basically compartment 16 or compartments.Under assembled state, compartment 16 forms a plurality of enclosed volumes thus between pad 13 and concrete frame 2.Certainly, compartment 16 can also have except that shown in shape the shape.Some that each compartment 16 receives in the noise; And the wall construction that forms device 14 by means of air gap prevents the diffusion of noise in air gap 15; The wall construction that this air gap forms device 14 has curved surface, and this curved surface relies on their thus obtained rigidity that the noise transmission between the compartment is minimized.Thus, mainly in each compartment 16, absorb noise individually.This type of noise absorber is called as " local reaction type absorber ".This absorber type be characterized as absorption factor absorbing the maximum value place higher in, be used for this and absorb peaked frequency and can be easier to adapt to desired frequency range.
Fig. 5 shows a part and the wall 17 thereof that forms device 14 in this air gap that is made of plastics in more detail; This wall 17 has the higher curved surface of rigidity and forms the compartment 16 of sealing; When this air gap formed device formation gap, this air gap forms device also made noise absorber 3 become so-called " local reaction absorber ".This means that forming device 14 through air gap prevents to spread to the next door in noise absorber 3 at a local noise that gets into through pad 13.The noise of reflection must leave with the identical path, path that it enters into noise absorber 3 on the edge now.Like this, noise absorber 3 is " local reactions ".For the local reaction absorber, be with regard to the frequency range that reduces of the maximum of unit with regard to causing with a plurality of dB (A), be easier to control and absorb maximum value.For in this for the solid wall the concrete frame, or even the noise that tilt to get into also will be at its absorption peak of frequency place discovery of being confirmed by the width of the thickness of pad 13 and air gap.
Fig. 6 shows and is being placed on railroad track 19 next doors on the sleeper 20, is being placed on by the innovative acoustics screening arrangement 1 according to Fig. 1 on gravel/gravelly bed 18.Railway bed 21 is made up of coarse rubble usually.Rugosity in the material can be passed noise and can't be eliminated in addition.Therefore, this acoustics screening arrangement 1 preferably is placed on the bed 18 that is made up of the thin material such as cobble, should thin material can also be compacting and slyness so that itself and do not allow noise to pass through with undesirable degree.For example, will keep separating than thin material and rubble by means of geotextile 22.
Fig. 7 shows the curve map as the noise absorption factor of the function of frequency; The so-called noise absorption characteristic that is used for innovative noise absorber/box 3; Noise absorption pad 13 big thickness are about 10mm, and fill up 13 and concrete frame 2 between have the air gap 15 of about 30mm.In this, for the noise in the frequency range that is in 700Hz-1050Hz, obtain noise absorption factor＞0.9, this frequency range is particularly suitable for the optimal inhibition from the noise of track traffic.Increasing or reducing under the situation of width of air gap 15; In other frequency range, obtain more effective noise suppression; This other frequency range can with other type such as the highway communication noise to bother noise relevant; Compare with for example rail noise, this highway communication noise requires low-frequency slightly noise absorption maximum value.It is not utilize air gap to form device, promptly only in the gap, have air and do not have the absorption factor that is obtained under the situation of so-called " non local response type " of local compartment 16 that dash line in the curve map has shown at absorber.Can see from continuous black curve; Under the situation of the absorption that utilizes air gap formation device and " local reaction characteristic "; Obtain the better noise absorption maximum value that forms; Through changing the width of air gap, this better noise absorption maximum value that forms can be easy to adapt to the specific noise Source Type such as highway communication or track traffic.
Fig. 8 shows a plurality of innovative modules and how to be assembled together the noise barrier of placing along the either side of railroad track to form.The top section 6 of module is provided with smooth basically upper surface 10; This smooth basically upper surface 10 makes top section 6 for example need to be trampled by the people from train evacuation/removing, and this train is for example owing to minor accident, mechanical breakdown, fire etc. quit work.The upper surface 10 of top section 6 can also be provided with non-slip patterns such as the checker plate pattern to help to trample and reduce the risk that slips.Can the suitable anti-skidding guard member that be made up of suitable non-conducting material be assembled on the upper surface 10 of top section 6.Patterning can also have certain influence to the propagation of the noise of effusion between train and acoustics screening arrangement 1.This module can also be provided with step 23 on the rear side of centre portion 5, for the personnel that evacuate, step 23 makes the arrival railway bed become more easy.
This module can also be provided with egress door 24 fully.In this case, this module is provided with the centre portion 5 that passes framework 2 and the recess/opening 25 of top section 6.Opening 25 is closed by door 24; This door 24 is closed through for example spring action (not shown) automatically, and is locked down in off position to prevent that their from for example being opened and preventing thus to reduce the noise suppression effect of acoustics screening arrangement 1 from the air pressure accident of train.Can discharge this locking, and door 24 is for example opened through the pressure at right angle against the top of door 24.
Fig. 9 shows the noise barrier in more detail and how to show door 24 is arranged in the opening 25 of module and evacuates from orbital region with the permission personnel.
Be placed on module on the end section of acoustics screening arrangement 1 and stand, and preferably be configured with the upper surface (not shown) of inclination than the remarkable big power of other module in the barrier.These modules can also be provided with box/noise absorber 3.
Utilizing the present invention, is possible with the small number of components part with simple, the compact and cheap unit of bothering noise that acoustics screening arrangement 1 is configured to suppress effectively from highway and railway thus.In addition, acoustics screening arrangement 1 according to the present invention is by means of its structure opposing different climate and can be easy to for example to utilize water takes out stains.Acoustics screening arrangement 1 according to the present invention is located substantially on this fact on the rear side of framework 2 by means of base portion 4, ground supporting portion; Can also be placed with near bothering noise source; And can be thus overflow between suspension arrangement (bogie) space that noise forms in the side by the bottom side of trolley coach and passenger vehicle and the acoustics screening arrangement preventing to a greater extent, yet allow railroad track is carried out conventional maintenance.
