高速公路波形梁护栏加高技术探讨

Heightening Technique of Expressway Wave Beam Guardrail

针对高速公路路面大中修过程中路面加铺造成的波形梁护栏防撞高度不能满足规范要求的现象,详细介绍了套管加高法和偏心防阻块法两种护栏加高的设计及施工方法,这两种方法具有造价低、施工快捷、适应性强的特点,有较强的实用价值。

According to the phenomenon that the wave beam guardrail anti-collision height can not meet the requirements of specification due to road surface paving in maintenance process of expressway pavement, two guardrail heightening design and construction method that are the casing heightening method and eccentric prevention block method are introduced in detail. The two methods have the characteristics of low cost, quick construetion, strong adaptability, and strong practical value.
