Abstract
The utility model discloses a novel concrete sound barrier, including sound absorbing layer and puigging, link to each other through the spring between sound absorbing layer and the puigging, be equipped with the cavity between sound absorbing layer and the puigging, the cavity intussuseption is filled with soundproof cotton, the sound absorbing layer upper surface is equipped with a plurality of sound holes of inhaling, the cuboid that the sound absorbing layer is shale ceramsite, excel in modified cement and water pressure system form, the puigging is gold tail ore sand concrete layer. The utility model discloses ore sand concrete layer regards as the puigging with the gold tail, avoids a large amount of tailing polluted environments, and changing waste into valuables has apparent economic benefits and social.
Description
Technical field
The utility model relates to a kind of sound barrier, is specifically related to a kind of new concrete sound barrier.
Background technology
Along with the fast development of China's economic society, the style of economic increase that tradition is extensive, make the contradiction of china natural resources shortage more and more outstanding, environment stress is also increasing.Golden production generally adopts cyanidation gold-extracted method, must add cyanide in this activities, causes mine tailing also residual a certain amount of cyanogen.Due to the process of gold tailings many employings bin system, along with the expansion of golden production scale and the prolongation of production history, gold tailings accumulating amount increases year by year, not only takies a large amount of soil, atmosphere pollution, surface water and groundwater; And a lot of Tailings Dam exceeds the time limit or overburden uses, even violation operation, makes Tailings Dam there is very big potential safety hazard.In addition, Tailings Dam build and maintenance management also need to drop into substantial contribution.Therefore, accelerate advance gold tailings process and fully utilize extremely urgent.
Meanwhile, existing concrete acoustical barrier sound insulation erasure effect is poor.
Utility model content
For solving the problem, the utility model provides a kind of new concrete sound barrier, using gold tailings sand concrete layer as puigging, avoids a large amount of tailings pollution environment, turns waste into wealth, have significant economic benefit and social benefit.
For achieving the above object, the technical scheme that the utility model is taked is:
New concrete sound barrier, comprise sound absorbing layer and puigging, be connected by spring between sound absorbing layer and puigging, cavity is provided with between sound absorbing layer and puigging, Sound-proof material is filled with in cavity, described sound absorbing layer upper surface is provided with some sound-absorption hole, and described sound absorbing layer is the cuboid of haydites of book structure, high-strength modified cement and hydraulic pressure system, and described puigging is gold tailings sand concrete layer.
As preferably, the inwall of described sound-absorption hole and cavity is coated with acoutic fibre board coating.
As preferably, the Thickness Ratio of described sound absorbing layer, puigging and cavity is 2: 4: 1.
The beneficial effects of the utility model are:
Using gold tailings sand concrete layer as puigging, avoid a large amount of tailings pollution environment, turn waste into wealth, there is significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model embodiment provides a kind of new concrete sound barrier, comprise sound absorbing layer 1 and puigging 2, be connected by spring 3 between sound absorbing layer 1 and puigging 2, be provided with cavity 4 between sound absorbing layer 1 and puigging 2, be filled with Sound-proof material in cavity 4, described sound absorbing layer 1 upper surface is provided with some sound-absorption hole 5, described sound absorbing layer 1 is the cuboid of haydites of book structure, high-strength modified cement and hydraulic pressure system, and described puigging 2 is gold tailings sand concrete layer.
As preferably, the inwall of described sound-absorption hole 5 and cavity 4 is coated with acoutic fibre board coating.
As preferably, the Thickness Ratio of described sound absorbing layer 1, puigging 2 and cavity 4 is 2: 4: 1.
Wherein, described spring 3 is socketed to form by inner spring and outer spring, is also provided with protection muscle in described inner spring, and this concrete proportioning implementing gold tailings sand concrete layer is portland cement 465kg/m
3, water 165kg/m
3, polycarboxylate water-reducer 15kg/m
3, the gold tailings sand 635kg/m of particle diameter 0 ~ 5mm
3, the stone 960kg/m of particle diameter 5 ~ 20mm
3.
This is specifically implemented using gold tailings sand concrete layer as puigging, avoids a large amount of tailings pollution environment, turns waste into wealth, have significant economic benefit and social benefit.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
