摘要
随着国民经济的飞速发展和交通量的激增,社会公共设施的建设也不断完善,其中高速公路已成为一项重要的基础建设项目。而且对高速公路进行改扩建已经成为我国高速公路工程建设方面的重要部分。从目前高速公路改扩建施工的情况来看,路基拼接对高速公路改扩建工程的施工质量和施工效果有着重要的影响。掌握高速公路改扩建路基拼接关键技术,不但能够满足高速公路改扩建工程的实际需要,而且也提高了高速公路改扩建施工过程中路基工程的施工质量。因此,提高对高速公路改扩建工程中路基拼接施工的技术掌握,在高速公路改扩建施工全面应用路基拼接技术是十分必要的。为此,文章主要针对高速公路改扩建拼接方式,增强路基拼接部位的压实度及提升软土地基的处理等方面的处理,对路基拼接施工技术展开深入探讨。
With the rapid development of national economy and the rapid increase of traffic volume,the construction of social public facilities has been constantly improved,and highway has become an important infrastructure project.Moreover,the reconstruction and expansion of expressway has become an important subject of highway engineering construction in China.From the current situation of expressway reconstruction and expansion projects,subgrade splicing construction has an important impact on the construction quality and effect of expressway reconstruction and expansion projects.Mastering the key technology of roadbed splicing in expressway reconstruction and expansion can not only meet the actual needs of expressway reconstruction and expansion,but also improve the construction quality of highway roadbed.Therefore,it is very necessary to strengthen the technical mastery of subgrade splicing construction in highway reconstruction and expansion,and to apply subgrade splicing technology in highway reconstruction and extension construction in an all-round way.For this reason,this paper mainly deals with the ways of highway reconstruction and expansion splicing,strengthening the compactness of subgrade splicing and improving the treatment of soft soil foundation,etc,and deeply discusses the construction technology of subgrade splicing.
