随着经济的快速和发展和各地区之间经济文化交流的日益密切,我国的公路事业获得了巨大的进步,尤其是高速公路对于我国的经济发展起着不可或缺的重要作用,然而在高速公路的运行过程中,往往会因多种因素出现路面沉陷以及裂缝等多种不良影响,为此我们应当加强路基注浆加固施工技术的研究,保证高速公路路基的安全与稳定。本文基于此以某高速公路为例,首先介绍了该公路的路基注浆加固工程概况,然后从注浆加固处理方案、注浆前期准备工作、注浆加固施工工艺和注浆加固施工质量评价四个角度分析和研究了高速公路路基注浆加固施工技术。
With the rapid economic development and the increasingly close economic and cultural exchanges among different regions, the highway industry in our country has made tremendous progress. In particular, the expressway plays an indispensable and important role in the economic development of our country. However, at a high speed During the operation of highway, many adverse effects such as road surface subsidence and cracks are often caused by many factors. Therefore, we should strengthen the research on construction technology of grouting and reinforcement of roadbed to ensure the safety and stability of expressway subgrade. Based on this, taking an expressway as an example, this paper firstly introduces the general situation of the roadbed grouting and reinforcement project, and then from the four aspects of grouting reinforcement scheme, grouting preparatory work, grouting reinforcement construction technology and grouting reinforcement construction quality evaluation Analysis and study of the highway subgrade grouting reinforcement construction technology.
