河道治理工程砂砾料堤防填筑施工工艺

Construction Technology of Sand Gravel Embankment Filling in River Regulation Project

纵观国内现阶段河道治理工程,河道内资源循环利用成为趋势,采用河道疏浚开挖的砂砾料用于两岸堤坝填筑,但河道开挖料通常为较大粒径砂砾料,其粘聚性差、遇水而实、缺水而散,在堤防填筑中压实质量较难控制。通过桑干河综合整治工程实践经验,对中粗砂、土砂所比较高的河道砂砾料堤防填筑施工工艺及质量控制措施进行探究,以达到高质量、高效率、经济适用的目的。

Throughout the current domestic river regulation projects, the recycling of resources in the river channel has become a trend, and the sand gravel excavated by river dredging is used for embankment filling on both banks. However, the excavated materials in the river channel are usually sand gravel with larger grain size, which have poor cohesiveness, are solid when encountering water, and disperse when lacking water. It is difficult to control the compaction quality in embankment filling. Based on the practical experience of Sanggan River comprehensive regulation project, the construction technology and quality control measures of river sand gravel embankment filling with high medium coarse sand and soil sand ratio are explored to achieve the purpose of high quality, high efficiency and economic applicability.
