在我国社会和经济不断发展的条件下,我国高速公路建设规模变得越来越大,随之而来的公路路基沉陷问题也更加突出,公路施工工序、施工质量控制、路基设计水平以及环境地质条件等因素都会导致公路路基病害的出现。而对于公路路基沉陷问题,普遍采用的一种快速有效处治技术就是注浆处治技术,其可以解决高速公路路基出现的沉陷病害。本文主要对南厦高速公路A8合同段K47+800汽车通道两侧台背沉降具体注浆处治技术进行研究,提出笔者的一些思考和建议,仅供参考。
Under the condition of continuous development of our society and economy, the scale of expressway construction in our country has become larger and larger. The subsidence of highway subgrade has also become more prominent. The construction procedures, construction quality control, subgrade design level and environmental geology Conditions and other factors will lead to the emergence of roadbed disease. As for the subgrade settlement of highway subgrade, a commonly used rapid and effective treatment technology is the grouting treatment technology, which can solve the subsidence diseases of highway subgrade. This paper mainly studies on the concrete grouting technology of mending settlement on both sides of K47 +800 car passage of A8 contract section of Nanxia Expressway, and puts forward some thoughts and suggestions of the author for reference purposes only.
