南水北调中线工程辉县七标湿陷性黄土状土需处理长度为2235.4m。由于黄土状土的湿陷变形将影响渠坡和渠基稳定,按照设计图纸处理方式为强夯、重夯和土挤密桩。在强夯施工前要做好工艺性试验,以确定施工参数,指导渠道强夯处理施工。
In the midline of the South-to-North Water Diversion Project, the length required for the treatment of collapsible loess in the Seventh Sewage of Huixian County is 2235.4 m. As the deformation of loess-like soil will affect the slope slope and drainage foundation stability, according to the design drawings for the dynamic compaction, ram and soil compaction pile. In the ram construction workmanship should be done before the test to determine the construction parameters, guide the channel dynamic compaction construction.
