Description
Technical field
The utility model belongs to railway component technology field, is related to a kind of lightweight acoustic barrier member.
Background technology
In recent years, China express railway cause was fast-developing.For example, Beijing-Tianjin inter-city, military wide high ferro, Beijing-Shanghai express railway are successively built
At putting into effect.High-speed railway brings great convenience to the trip of people；But at the same time, it is also caused to environment
A degree of pollution, such as when railway is by dense population areas, village, school, to people of noise caused by it
Habit, live and work bring puzzlement and inconvenience, therefore sound barrier comes into being.So-called sound barrier refers in sound source and receiving
Between person, insertion one can absorb sound or the plate or wall of sound insulation, and to make intensity of acoustic wave, there are one significant decaying, this " barriers
Hinder object " it is exactly sound barrier.
Currently, most sound barriers are made of entrant sound panel, sound insulation backboard and built-in sound-absorbing material.And entrant sound panel
Usually in the surface trepanning of sheet metal or glass epoxy, so that sound is passed into internal sound absorbing layer from hole, pass through suction
Absorption of the sound material to sound, makes sound wave be decayed and be prevented；Some entrant sound panel is by cement and to be chopped
After wood fibre is compound, sound absorbent surface layer is formed, in combination with internal cavity, sound wave is made to be decayed and be prevented.But this is several
Kind of sound barrier panel, in addition to because surface hole, and acoustic wave segment is made to penetrate, or because surface be fitted into it is sparse porous
Wood fibre, and acoustic wave segment is made to be absorbed；Quite a few sound wave is directly reflected back air because of the rigid surface of panel
In, to cause the superposition and reverberation of sound wave；Secondly as the use of a large amount of metals or inorganic material so that above-mentioned sound-screen
The construction weight for hindering component is larger, difficult, and construction is inconvenient.
CN102051843A discloses a kind of high speed railway sound barrier, including H profile steel metal upright post, is inserted into H profile steel metal
The precast concrete acoustic board of column, precast concrete acoustic board top is equipped with transparent sound insulationg board, on the top of transparent sound insulationg board
Arc sound absorption top is arranged in portion.The sound barrier structure for high speed railways of the invention is safe, endurance, durability is good, constructs
Facilitate, be conveniently replaceable, low cost, but the construction weight of above-mentioned acoustic barrier member is larger.
Yin Hao and Duan Jinming (Yin Hao, the progress of noise barrier structure form, the environmental protection committee of China Railway Association noise
Vibration group annual meeting papers for exchange collection, 2008,36~42；Duan Jinming, Zhou Jingxuan, the research of external road noise barrier structure type
Progress, highway, 2005 (6)：190~193) it points out, compared with rigid panel, the sound barrier of band " flexible pressure release surface " will be advantageous
Sustained release in sound wave and absorption.But so far, the domestic sound for not yet developing the flexibility that can effectively reduce noise or elasticity
Barrier.
