Abstract

本发明公开了一种高铁声屏障支撑柱，属环保领域，它由一个脚板、两根立柱、两块加强板、一块遮盖板组成，立柱具有U形凹槽，遮盖板为横截面呈L形金属板；两根立柱与脚板固定，两根立柱平行且U形凹槽的槽口朝外，两块加强板分别设置在两根立柱的两侧且将两根立柱连接为一体，加强板的顶部与立柱等高，加强板的底部与柱脚板具有20cm~60cm的距离，使立柱的下部留有检修操作空间；其中一块加强板的底部焊接遮盖板，遮盖板的另一边与脚板焊接；不设置遮盖板的一侧朝向铁路线。本发明使铁路线路侧的加强钢板与柱脚板留有一定距离的空隙，便于检修维护。

Description

一种防治高铁噪声的声屏障支撑柱
技术领域
本发明属环保领域，具体涉及一种防治高铁噪声的声屏障支撑柱。
背景技术
        高铁列车运行时产生的噪声对高铁沿线附近居民、学校和办公区等环境敏感点产生较大的噪声污染。目前主要通过设置声屏障对噪声的传播途径进行阻挡，从而达到防治噪声污染的目的。
发明内容
本发明的目的旨在提供一种结构简单、经济实用、便于检修维护的高铁声屏障支撑柱，解决了原来铁路声屏障由于声屏障单元板的阻挡，不易检修维护柱脚螺栓螺母的难题，便于日常维护检修。
       为达到上述目的，本发明采用如下解决方案:
一种利于检修的高铁声屏障支撑装置，由一个脚板、两根立柱、两块加强板、一块遮盖板组成，立柱具有U形凹槽，遮盖板为横截面呈L形金属板；两根立柱与脚板固定，两根立柱平行且U形凹槽的槽口朝外，两块加强板分别设置在两根立柱的两侧且将两根立柱连接为一体，加强板的顶部与立柱等高，加强板的底部与柱脚板具有20 cm~60 cm的距离，使立柱的下部留有检修操作空间；其中一块加强板的底部焊接遮盖板，遮盖板的另一边与脚板焊接；不设置遮盖板的一侧朝向铁路线。
本发明的原理是加强钢板与柱脚步板之间留有一定距离的空隙，便于检修维护。并用遮盖板将铁路外侧加强钢板下方空间遮盖。而槽钢便于声屏障单元板插入。
与现有技术相比，本发明具有如下优点：
1、本发明在降噪效果不受影响的情况下，解决了日常无法维修维护铁路线外侧螺栓的难题。
2、本发明经济使用，使用便捷。
附图说明
图1是本发明实施例的结构图。
图中：1、槽钢，2、加强板，3、脚板， 4、遮盖板，5、柱脚螺栓孔，6、吊装孔。
具体实施方式
实施例：图1所示，将两根槽钢1(即为立柱)焊接在脚板3左右两侧上，两根槽钢之间的两侧用加强板2焊接，加强板2下部与柱脚板3具有20 cm~60 cm的距离，的距离，加强板2上部与槽钢1等高。与铁路线背向的一侧的加强钢板下方用遮盖板4遮盖，遮盖板4上部与加强板2焊接，遮盖板4下部和脚板3焊接。

Claims (1)

1.一种防治高铁噪声的声屏障支撑柱，由一个脚板、两根立柱、两块加强板、一块遮盖板组成，立柱具有U形凹槽，遮盖板为横截面呈L形金属板；两根立柱与脚板固定，两根立柱平行且U形凹槽的槽口朝外，两块加强板分别设置在两根立柱的两侧且将两根立柱连接为一体，加强板的顶部与立柱等高，加强板的底部与柱脚板具有20 cm~60 cm的距离，使立柱的下部留有检修操作空间；其中一块加强板的底部焊接遮盖板，遮盖板的另一边与脚板焊接；不设置遮盖板的一侧朝向铁路线;两个立柱的槽口为背向，即一个槽钢的槽口朝左，另一个槽钢的槽口朝右，声屏障单元板插在两根槽钢之间;所述遮盖板由水平面和竖直面构成，水平面和竖直面之间成90—160度角，水平面的面积小，竖直面的面积大，水平面和加强板焊接，竖直面和脚板焊接。
