桥涵台背回填质量控制的实践与探索

Practice and exploration of bridge and culvert backfill quality control

随着中国基础设施网络及交通体系的不断完善,公路、桥涵施工技术也随之不断进步。但其间,桥涵台背回填依然是业内施工的主要难点和质量控制关键点。以某道路工程为背景,结合工程实例和施工经验,依次分析桥涵台背回填的各阶段质量问题的成因,并对质量控制措施实践经验进行分析探索,为从事桥涵勘察、设计、施工及维养工程技术人员提供借鉴。

With the continuous improvement of China’s infrastructure network and transportation system, highway and bridge culvert construction technology has also been continuously improved, but the backfilling of bridge.But in the meantime, culvert and abutment is still the difficulty and the key point of quality control in the construction industry.In the context of a road project, With a road project as the background, Combined with engineering examples and construction experience, analyze the causes of quality problems in each stage of backfilling of bridges and culverts in turn, and analyze and explore the practical experience of quality control measures, provide reference for engineering technicians engaged in bridge and culvert survey, design, construction and maintenance.
