近年来,随着我国社会的不断发展和经济快速提升,公路施工项目呈现出逐步增加的趋势。在公路施工中,高压旋喷桩属于比较常见的一种施工技术,它主要呈现出较少的占地面积、很小的振动、简单的技术工艺和便捷的施工方式等特点,它不但能够应用于狭窄的场地,而且能够应用于陡峭的坡地,该施工方法在公路地基加固中得到广泛的推广和应用。当前一个时期,公路建设规模的不断扩大对其质量提出了越来越高的要求,为了使公路施工质量得到有效提高,使施工成本投入不断减少,将高压旋喷桩施工技术应用于公路施工中很有必要。本文主要围绕高压旋喷桩施工技术概述,重点分析了高压旋喷桩施工技术施工准备工作、施工工艺和技术要点,以期能为有关方面的需要提供参考借鉴。
In recent years, with the continuous development of our society and rapid economic growth, road construction projects have shown a gradual increase. In road construction, high-pressure rotary jet grouting pile is a kind of common construction technique, which mainly shows less land occupation, small vibration, simple technical process and convenient construction method, which not only can be applied In narrow sites, but also can be applied to steep slopes, the construction method in the reinforcement of highway foundations has been widely promoted and applied. In the current period, the continuous expansion of highway construction has put forward higher and higher requirements on its quality. In order to effectively improve the quality of highway construction and reduce the investment in construction costs, the construction technology of high-pressure rotary jet grouting pile is applied to the construction of highways necessary. This article focuses on the construction of high pressure rotary jet grouting technology overview, focusing on analysis of high pressure rotary jet grouting pile construction technology construction preparation, construction technology and technical points, in order to provide a reference for the needs of the parties concerned.
