Abstract
The utility model relates to a noise barrier for high speed railway to avoid noise, which comprises a crust and a sound absorption layer, the crust covered the sound absorption layer outside, also comprises a nano waterproof coating arranged on the surface of the sound absorption layer. Comparing to the prior art, the utility model has merits of waterproof, good noise reduced effect dipped in rain; whole nonmetal (static proof, lightning proof, anticorrosion, low maintenance cost, low cost); anti strong air dynamical bearing; good noise reduction effect, heat resistance, antifreeze, long project life and so on.
Description
Technical field
The utility model relates to the noise protection device, relates in particular to a kind of sound barrier that is used for the high-speed railway noise protection.
Background technology
Along with the development of railway technology, the popularization of high-speed railway, more existing sound barrier fault devices can not meet the demands gradually.High-speed railway train design speed per hour reaches 350km/h, and train is different from the common railway train through the noise spectrum of out-of-date generation, simultaneously train by the time surrounding buildings produced great air press.The following several schemes of the many employings of sound barrier in the past: outer cover of steel plate, sound absorption materials such as interior filling aluminum fiber, aluminum fiber is the loose secondary environmental pollution that causes easily, and outer cover of steel plate need regularly be done anticorrosion maintenance; The multilayer perforated acoustic board then passes through composite assembly, and this type of barrier noise reduction is stable inadequately; Glass fibre reinforced plastics casing, filling sucting sound material in rainproof layer, the many employings of waterproofing course directly are wrapped in the mounting means of sound absorption material outside, in use may cause come off aging, thereby make the reduction of sound barrier noise reduction.
The utility model content
The purpose of this utility model is exactly a kind of sound barrier that is used for the high-speed railway noise protection that a kind of waterproof and anti-strong airload are provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of sound barrier that is used for the high-speed railway noise protection, comprise shell, absorbent treatment, described shell is wrapped in the absorbent treatment outside, it is characterized in that, also comprise the nano water-proof coating, described nano water-proof coating is located at the absorbent treatment surface.
Described sound barrier adopts full nonmetals.
Described shell adopts glass-reinforced plastic material.
Described absorbent treatment adopts the perlite material.
Compared with prior art, the utlity model has following advantage:
1, waterproof, immersion can keep good noise reduction in rainwater;
2, nonmetal entirely (maintenance cost is low for antistatic, anti-lightning strike, anticorrosion, and cost is low);
3, anti-strong airload;
4, excellent noise reduction effect, heat-resisting, freeze proof, the engineering life-span is long.
Description of drawings
Fig. 1 is a kind of front view that is used for the sound barrier of high-speed railway noise protection of the utility model;
Fig. 2 is a kind of A-A sectional drawing that is used for the sound barrier of high-speed railway noise protection of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As depicted in figs. 1 and 2, a kind of sound barrier that is used for the high-speed railway noise protection, comprise glass fibre reinforced plastics casing 1, absorbent treatment 3, described glass fibre reinforced plastics casing 1 is wrapped in absorbent treatment 3 outsides, also comprise nano water-proof coating 2, described nano water-proof coating 2 is provided with on absorbent treatment 3 surfaces, and described absorbent treatment 3 adopts the perlite material.
The utility model adopts full nonmetals, used glass fibre reinforced plastics casing 1 prolonging, on the basis of interior filling absorbent treatment 3, directly add and be coated with nano water-proof coating 2 at absorbent treatment 3, absorbent treatment 3 adopts the perlite material, can bear the following high-speed railway of speed per hour 350km/h and press through the out-of-date air that surrounding buildings is produced, airload is more than 2KPa.
Claims (4)
1. a sound barrier that is used for the high-speed railway noise protection comprises shell, absorbent treatment, and described shell is wrapped in the absorbent treatment outside, it is characterized in that, also comprises the nano water-proof coating, and described nano water-proof coating is located at the absorbent treatment surface.
