Description
Technical field
The present invention relates to a kind of integral type sound barrier.
Background technology
Sound barrier is to be used for absorbing and the through sonic propagation in noise isolation source, the sound absorption that between noise source and recipient, is provided with and the shielding harness that insulates against sound, and it is placed in the sound shadow region recipient, and propagation of noise is wherein had isolation effect preferably.Developing rapidly of high-speed railway produces a large amount of noise pollutions now, and sound barrier takes up an area of few, and fabrication and installation are convenient and swift, and construction investment is suitable, become the important measures of traffic noise pollution control.
Sound wave runs into that sound barrier can reflect, projection and three kinds of phenomenons of diffraction in communication process.Usually we think that sound barrier can stop through sonic propagation, and make system penetrate sound enough decay are arranged, and the influence of projection sound can be ignored.Therefore, the sound absorption effect of sound barrier generally can adopt the noise abatement amount to represent, it has reflected the ability of the above-mentioned two kinds of shielding entrant sounds of sound barrier.Between sound source and receiving station, insert a sound barrier, establish the sound barrier endless, sound wave can only be gone over from the top diffraction of barrier, and forms a sound shadow region thereafter, forms a shade that kind just as light is blocked by object.In this sound shadow region, people can feel that noise has obviously weakened, the noise reduction effect of Here it is sound barrier.
Between sound source and recipient, insert a facility, sound wave is propagated has a significant additional attenuation, thereby weakens the influence of noise in certain zone at recipient place, and such facility is called as sound barrier.Humorous sound barrier is widely used in countries in the world; Especially in recent years high-speed railway develops rapidly; Various countries have also carried out many research to high speed railway sound barrier, aspect the design and construction of high speed railway sound barrier, have also carried out deep research and a large amount of practices.
Chinese patent, the patent No. 200720080128.9 discloses a kind of integrated precast concrete sound barrier unit board; As shown in Figure 4; Said unit board comprises concrete acoustical barrier 201, and the acoustical board 202 that is arranged on concrete acoustical barrier 201 inwalls, and the whole basis 203 of passing through is connected with outside.
Chinese patent; CN201053108; A kind of integrated precast concrete sound barrier unit board that adds the high penetration sound barrier is disclosed; As shown in Figure 5, this unit board comprises the concrete acoustical barrier unit board 301 that height and train vehicle window height adapt, and the penetrating sound barrier 303 that directly is fixedly connected with concrete acoustical barrier unit board top.Be connected with acoustical board 302 at concrete acoustical barrier unit board 301 inwalls, this unit board is whole to link to each other with the outside through basic 304.
Above-mentioned known integral type sound barrier all need carry out concrete prefabricated, maintenance, and shortcomings such as workload is big, construction is inconvenient, speed of application is slow, acoustically effective difference also are not easy to be complementary with the site environment color simultaneously.
Summary of the invention
