Abstract

本发明提供一种隔音屏障结构，包括有多个两侧对称的侧部支撑架和多个顶部弧度高低不同的弧形支撑架单元组成，其特征在于，每个单元的左侧部支撑架由A部分和B部分两部分组成，右侧部支撑架由C部分和D部分组成，左侧部支撑架和右侧部支撑架组成主体支撑架。顶部支撑架由顶部支撑架F和顶部支撑架G组成，顶部支撑架和侧部支撑架相连，顶部支撑架G与侧部支撑架连接点高于顶部支撑架F与侧部支撑架的连接点。

Description

一种全封闭隔音屏障
技术领域
本发明属于环保领域，主要用于交通噪声治理，具体涉及一种全封闭隔音屏障。
背景技术
道路沿线有居民小区、学校、办公楼等诸多环境敏感点，由于车辆行驶产生的噪声对沿线环境敏感点造成很大的噪声污染。
发明内容
为了解决上述噪声污染问题，本发明提出一种隔声降噪效果好的全封闭隔音屏障。
一种隔音屏障结构，包括有多个两侧对称的侧部支撑架和多个顶部弧度高低不同的弧形支撑架单元组成，其特征在于，每个单元的左侧部支撑架由A部分和B部分两部分组成，右侧部支撑架由C部分和D部分组成，左侧部支撑架和右侧部支撑架组成主体支撑架。顶部支撑架由顶部支撑架F和顶部支撑架G组成，顶部支撑架和侧部支撑架相连，顶部支撑架G与侧部支撑架连接点高于顶部支撑架F与侧部支撑架的连接点，顶部隔音板安装在顶部支撑架F和顶部支撑架G之间，在顶部支撑架之间形成斜面，形成封闭的隔音屏障顶棚面。侧部隔音板安装在A部分和B部分之间，A部分和B部分形成两个斜面，侧部支撑架下端与所述地面基础通过柱脚螺栓相连接；
所述全封闭隔音屏障，当车辆行驶产生的噪声传播时，在所述全封闭声屏障内部形成噪声封闭隔离区，有效阻断噪声传播途径，同时由于侧部和顶部形成多个斜面，可以多次折射抵消噪声，从而隔离封闭传播途径和多次折射抵消噪声，达到良好的治理道路噪声的目的。
附图说明
图1是本发明全封闭隔音屏障结构框架图；
图2是本发明左侧支撑架图；
图3是本发明右侧支撑架图；
图4是本发明主体支撑架图；
图5是本发明顶部支撑架图；
图中，1、侧部支撑架A；2、侧部支撑架B；3、侧部支撑架C；4、侧部支撑架D；5、顶部支撑架F；6、顶部支撑架G；7、侧部隔音板；8、顶部隔音板；9、柱脚板；10、主体支撑架。
具体实施方式
某铁路，宽度11米，长度300米，道路两侧全部为学校和生活区。由于学校和生活区距离铁路很近，噪声污染严重。为彻底治理道路噪声污染，将正在道路上安装全封闭隔音屏障。
全封闭隔音屏障总高度7.5米。参照图1，本项目由75个左侧、右侧对称的支撑架和顶部支撑架组成，顶部支撑架和侧部支撑架相连，顶部支撑架G与侧部支撑架连接点高于顶部支撑架F与侧部支撑架的连接点(即顶部支撑架G6的高度比顶部支撑架F5高)，顶部隔音板安装在顶部支撑架F和顶部支撑架G之间，在顶部支撑架之间形成斜面，形成封闭的隔音屏障顶棚面。侧部隔音板安装在左侧支撑架A部分与B部分之间、C部分与D部分之间，A部分和B部分形成两个斜面，C部分和D部分形成两个斜面。左侧支撑架、右侧支撑架通过柱脚螺栓与地面基础连接。
全封闭隔音屏障内两侧高度5米处每间隔50米，两侧共设计了120个电气化列车所需的接触网连接架子，方便铺设接触网线路。
当列车行驶产生的噪声传播时，在所述全封闭声屏障内部形成噪声封闭隔离区，有效阻断噪声传播途径，同时由于侧部和顶部由多个斜面组成，可以多次抵消噪声反射，从而隔离封闭传播途径和多次抵消噪声，达到良好的治理道路噪声的目的。全封闭隔音屏障降噪效果好，造价低，外观优美，有效解决了铁路噪声的污染问题。
