Abstract
The combined sound-insulation protective screen includes side protective screens which are respectively mounted at two sides of two-way highroad or railway, and on the intermediate isolation band of two-way highroad or railway an intermediate screen is synchronously mounted, and the height of every screen is dependent on the height of buildings to be protected at two sides of highroad or railway. The top ends of protective screens are connected by using right safe bar, and the bottom portion of every protective screen is equipped with triangular support.
Description
Technical field
What the present invention relates to is a kind of highway and railway both sides built in, is used to stop the barrier device of noise diffusion, belongs to traffic noise control and field of environment protection.
Background technology
The device of existing traffic noise sound barrier mainly contains two kinds; first kind is the open type noise barrier; about its screen Senior Three rice; barrier length has tens meters or hundreds of rice or a few km not to wait; the application of this class sound barrier is comparatively general, but it has distinct issues, and promptly the height of barrier is not high; can only protect the crowd in high-rise building lower level building, be subjected to the pollution of traffic noise for the crowd of higher floor in the same old way.If improve the both sides barrier to the height that is enough to shelter from high-rise building; allow whole high-rise building all be among the sound shadow region; whole crowds are protected, certainly will bring safety problems such as wind resistance, also have that cost increases, street lamp is installed difficulty, influence problem such as view.Second kind is the tunnel type sound barrier, and automobile or train inside travel, and the both sides building is in the sound shadow region fully, and traffic noise is effectively controlled.The existing problem of this class barrier is also more outstanding, and the one, the cost height, the 2nd, the air in the barrier is stale unhygienic, and the ventilation problem is more difficult.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of two-way highway or railway in the middle of the installing in barrier, and through organic assembling, exceeding increase side barrier height, can make highway or railway both sides high building be in combined type umbra sound barrier in the full sound shadow region again, both sides or a side that it is included in two-way highway or railway are equipped with the side barrier, on the intermediate isolating band of two-way highway or railway, middle barrier is housed synchronously, the height of side barrier and middle barrier determines by both sides, road building height.
Described side barrier top is provided with one section to road one lateral buckling, and also is provided with one section to both sides or a lateral buckling on the top of middle barrier.
There is gusseted the root both sides of barrier in described, in the root outside of side barrier gusseted are arranged also, and the top of each barrier connects with rigidity safety muscle.
The present invention also is provided with the space of break-through in the bottom of middle barrier, it neither influences screen effect, and the material saving is arranged, and increases the effect of driver's seat in addition.
The present invention can make highway or railway both sides building to be protected all be among the sound shadow region of barrier; no longer there is the pollution of traffic noise in the residing acoustic environment of building; whole crowds of building have obtained protection bar none, and this is invisible environmental benefit and social benefit.The present invention combines according to Principles of Acoustics, so barrier needs the size that raises for realizing full sound shadow region, realizes that than existing both sides barrier the height of full sound shadow is much smaller, and does not have safety problem.The required material of the tunnel type sound barrier that compares, artificial will reduce a lot, and does not have problem such as ventilation, and this is tangible relatively economical benefit.
The height of each barrier of the present invention determines according to protected building height, and this is of the present inventionly will put the place, has embodied science and economy.Have rational in infrastructurely, easy for installation, safe and practical, can form large-scale sound shadow region, characteristics such as good defening effect are arranged.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is a structural representation of the present invention.
The specific embodiment
The sound barrier that Figure 1 shows that two-way highway is provided with arrangement diagram, with the four-lane highway is example, the both sides of highway are respectively arranged with side barrier 12, the vehicle 13 that travels on the left-hand lane, its noise can be blocked by left side barrier 12 left side high-rise building 14 major parts, but for right side high-rise building 15, most floors still are subjected on the left-hand lane driving vehicle 13 to its noise pollution.If be provided with intermediate isolating band 16 in the centre in track, the left and right sides.And it highly is by the decision of both sides barrier height, so situation and above-mentioned basic identical.
Shown in Figure 2, the present invention includes the A-frame of both sides at two-way highway 21 (also can a side) by the outside and support side barrier 22 is housed, barrier 27 during the A-frame by both sides on the intermediate isolating band 26 of this two-way highway 21 supports and is equipped with.The top of barrier 27 is to two lateral bucklings 28 in this, and the top of side barrier 22 is to road one lateral buckling 29.Described bending 28 and 29 not only can be rainproof but also can have been increased the scope of blocking noise.The height of barrier is determined to see shown in the accompanying drawing 2, left side high-rise building 24 is an AD rice highly, and No. 2 vehicles 23 that travel on the left-hand lane link to each other with the D point, draws the height GH rice of left side barrier, connect No. 4 vehicles 23 and D point line on the right-hand lane, the height MN rice of barrier 27 in drawing.Equally, connect No. 3 vehicles travelling on the right-hand lane and the peak P point of right side high-rise building 25, draw right side barrier height CE rice.Barrier 27 highly is that height according to the higher building of either side decides in described.The bottom of barrier 27 is provided with the space 30 of break-through in of the present invention, and the height in its space is by the MO rice of the line decision of No. 2 vehicles of left-hand lane and barrier summit, right side E.
The present invention considers the safety guarantee problem of barrier, and the safe muscle 31 that has been rigidly connected on the top of barrier makes side barrier, middle barrier become integral body, and is interdependent each other, at the root of barrier gusseted is arranged.
Claims (4)
1 one kinds of combined type umbra sound barriers, the side barrier is equipped with in the both sides that it is included in two-way highway or railway, it is characterized in that on the intermediate isolating band (26) of two-way highway (21) or railway middle barrier (27) being housed synchronously, the height of side barrier (22) and middle barrier (27) determines by both sides, road building height.
