Abstract
The utility model discloses a rail transit arc and short sound barrier which comprises a sound barrier base. An arc sound barrier stand column is arranged on the upper portion of the sound barrier base, and the arc sound barrier stand column comprises two parallel arc stand columns. A sound absorption shield body is arranged between the two parallel arc stand columns, and sound absorption wedges are arranged at the arc inner side of the arc sound barrier stand column. The rail transit arc and short sound barrier is simple and lively, an arc shape of the upper portion of the arc sound barrier stand column extends to the limit of equipment to the maximum, and the sound absorption wedges of the lower portion of the arc sound barrier stand column greatly improve noise reduction effect of rail noise by the sound barrier. The technical problem of the short sound barrier is effectively solved, and bridge stress and landscape effect are well facilitated, and meanwhile work amount is greatly reduced.
Description
Technical field
The utility model belongs to rail transit noise control technology field, particularly a kind of short sound barrier of track traffic circular arc type of using urban track traffic.
Background technology
Track traffic has become and solves traffic above-ground and block up, improve one of the most effective control means of people's trip.Meanwhile, the vibration of track traffic and noise pollution become the outstanding factor that influences urban environment day by day.The noise that track traffic produces is the problem that can not ignore, and it disturbs people's work study, infringement people's physical and mental health, severe noise even can make area along the line lose original function, the commercial value in influence area along the line.How to take to administer to arrange and drag that to eliminate or reduce the noise pollution that track traffic brings be one of importance of track traffic research.
The urban track traffic Noise Prevention and Treatment is a comprehensive system engineering, and the sound barrier technology is a kind of effective measures of controlling rail transit noise.Sound barrier is to stand on noise source and be subjected to acoustics baffle between the sound point.The main sound barrier great majority that adopt are higher sound barrier at present, and main cause is that high formula sound-screen screen noise reduction is better than short sound barrier.
At the characteristics of track traffic, it is lightly lucid and lively to be positioned at the bridge that elevated line arranges, and sound barrier is set need considers that bridge bearing, wind carry restraining factors such as stressed, observation, environmental harmony, landscape effect.
The utility model content
The utility model has overcome shortcoming of the prior art, provide a kind of track traffic circular arc type short sound barrier, when satisfying the requirement of track traffic sound insulation and noise reducing, guaranteed whole landscape effect and passenger's sight line has not been produced to block, and short sound barrier provides advantageous conditions to integral bridge stability.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The short sound barrier of track traffic circular arc type, comprise the sound barrier base, described sound barrier base top arranges camber sound barrier column, described camber sound barrier column comprises two parallel circular arc type columns, between the described two parallel circular arc type columns gobo body is set, described camber sound barrier column lower inside arranges wedge absorber.By the height equivlent principle of non-erect type sound barrier as can be known, the short sound barrier height equivlent of circular arc type equals sound source to the height of the intersection point that hinders top line and upstanding portion extended line.
Further, described camber sound barrier column comprises bottom vertical section and top arc section.
Further, described wedge absorber is fixed in described bottom vertical section.
Further, described wedge absorber is right-angled triangle, and the inclined-plane of described right-angled triangle is towards track wheel track direction, and the employing sound absorption construction.
Further, described sound barrier base is inverted U-shaped.
Further, described sound barrier base pinch places bridge barricade top, by being fixed on the barricade wearing high-strength bolt.
Further, described gobo body is located between the two parallel circular arc type columns with the plug-in card form.
Further, described gobo body by snap fit between two parallel circular arc type columns.
Compared with prior art, the beneficial effects of the utility model are:
The short sound barrier of track traffic circular arc type described in the utility model is succinct, lucid and lively, the wedge absorber that camber sound barrier column top circular arc is stretched to facilities clearance and bottom has to greatest extent greatly improved the noise reduction of sound barrier to the track noise, solved the technical barrier of short sound barrier effectively, very be conducive to bridge force-bearing and landscape effect, engineering quantity also reduces significantly simultaneously.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not constitute to restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the short sound barrier of track traffic circular arc type described in the utility model.
Among the figure, 1---the sound barrier base; 2---camber sound barrier column;
3---the circular arc type column; 4---the gobo body;
5---wedge absorber; 6---the bottom vertical section;
7---the top arc section; 8---high-strength bolt;
9---buckle.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
Consult Fig. 1, the short sound barrier of track traffic circular arc type described in the utility model, comprise sound barrier base 1, sound barrier base 1 top arranges camber sound barrier column 2, camber sound barrier column 2 is overall structure with sound barrier base 1, camber sound barrier column 2 comprises between the parallel circular arc type column 3 of two parallel circular arc type columns 3, two gobo body 4 is set that the arc inboard of camber sound barrier column 2 arranges wedge absorber 5.
Camber sound barrier column 2 comprises bottom vertical section 6 and top arc section 7, wedge absorber 5 is fixed in bottom vertical section 6, bottom vertical section 6 requires to arrange according to bridge wall height and wedge absorber 5 setting height(from bottom)s, and top arc section 7 stretches to orbital direction, the track wheel track is made an uproar to form cover.
Wedge absorber 5 is right-angled triangle, and the inclined-plane of right-angled triangle is towards track wheel track direction, and the employing sound absorption construction, has greatly improved the noise reduction of sound barrier to the track noise.
Sound barrier base 1 is inverted U-shaped, and sound barrier base 1 directly is folded in the employing of bridge barricade top and fixes wearing high-strength bolt 8 connection barricades.The fixed form of usually general elevated bridge sound barrier is to fix at barricade top plantation bolt or pre-embedded bolt form, sound barrier base 1 is designed to inverted U-shaped, be to solve orbit traffic overhead bridge barricade width than the little characteristics of general elevated bridge, by being fixed in bridge plate washer top to wearing high-strength bolt 8.
Gobo body 4 is located between the two parallel circular arc type columns 3 with the plug-in card form, is fixed in the circular arc type column 3 by buckle 9.Wedge absorber 5 is positioned at the bottom vertical section 6 of circular arc type column 3, is fixed on bottom vertical section 6 columns.
