Abstract
The utility model provides an ecological acoustic barrier structure, which comprises a soil body wall with a narrow upper part and a wide lower part. The soil body wall is formed by mechanically tamping earthworks layer by layer, each layer of the earth work is wrapped by a geotechnical grid, and planting bags filled up with shrubs or plants are arranged on each layer of earthwork close to both sides and the top of the soil body wall. The ecological acoustic barrier structure also has the advantages of good noise reduction, simple structure, easy construction and maintenance, low price, good landscape effect, etc.
Description
(technical field)
The utility model relates to a kind of ecological acoustic barrier structure, be mainly used in the sound insulation and noise reducing in the traffic urban operating mechanisms such as speedway, overhead composite road, urban light rail subway, also can be used for the sound insulation and noise reducing of factory, speedway, railway engineering and other noise source.
(background technology)
The tradition sound barrier mainly is made up of steel work column and sound absorption screen board two parts, and column is the main bearing member of sound barrier, and it is by bolt or be weldingly fixed on the pre-embedded steel slab on crashproof wall of road or track limit; Felt is main sound insulation sound absorbing member, and it is fixed in the H type column groove by high-strength spring clip, forms sound barrier.
The tradition sound barrier though broken the unicity of former frame construction at present, has certain humanism connotation because of the characteristics of its structure, does not have the function of ecological protection.
(summary of the invention)
The purpose of this utility model just provides a kind of ecological acoustic barrier structure, and it can combine sound absorption and sound insulation effectively, and decrease of noise functions is good.
The purpose of this utility model is achieved in that a kind of ecological acoustic barrier structure, comprise the soil body wall 1 that a top is narrow, the bottom is wide, soil body wall is by cubic metres of earth 4 adopting the machinery compacting to form from level to level, each layer earthwork is wrapped with geo-grid 2, has admixed the plantation bag 3 of shrub or flowers and plants near soil body wall both sides and top each layer earthwork setting.
Owing to adopt said structure, soil body wall 1 has ensured the sound insulation function of ecological acoustic barrier, geo-grid 2 is as the reinforced structure of ecological acoustic barrier, reached the requirement of structural strength with stability, plantation bag 3 provides nutrient matrix for plant growing, formation can absorb the ecological community of noise energy, given prominence to the double action of ecological sound-absorbing and ecological protection, so the utility model decrease of noise functions is good, also have simultaneously simple in structure, be easy to construction and maintenance, cheap, remarkable advantage such as landscape effect is good.
(description of drawings)
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
(specific embodiment)
As shown in Figure 1, a kind of ecological acoustic barrier structure, comprise the soil body wall 1 that a top is narrow, the bottom is wide, soil body wall is by cubic metres of earth 4 adopting the machinery compacting to form from level to level, each layer earthwork is wrapped with geo-grid 2, has admixed the plantation bag 3 of shrub or flowers and plants near soil body wall both sides and top each layer earthwork setting.
During construction, by adopt the location of sound barrier at needs, after adopting road roller that ground is carried out compaction treatment, the artificial geo-grid 2 of laying, then after piling up the plantation bag 3 of admixing shrub, flowers and plants on the grid with the geo-grid anti-package, the earthwork in the artificial backfill noise barrier also adopts the machinery compacting to form soil body wall 1, so repeatedly up to the design elevation position.At last, ecological acoustic barrier is carried out maintenance management, form up to plant barrier system 5.
Claims (1)
1, a kind of ecological acoustic barrier structure, it is characterized in that: comprise the soil body wall (1) that a top is narrow, the bottom is wide, soil body wall adopts the machinery compacting to form by cubic metre of earth (4) from level to level, each layer earthwork is wrapped with geo-grid (2), has admixed the plantation bag (3) of shrub or flowers and plants near soil body wall both sides and top each layer earthwork setting.
