Treatment Technology of Underground Runoff Hidden Culvert Interception and Water Logging Damage in Baozitan Village, Liuquan Township, Hongsibao District, Ningxia

In order to address the issues of rising groundwater level, sinking of building foundations, and collapse in Leopard Beach Village, Liuquan Township, Hongsibao District, water resource utilization surveys and hydrogeological surveys were conducted to explore the sources and reasons for the rise of groundwater in the village. Both water saving irrigation schemes and control schemes for reducing groundwater runoff were proposed, including well interception, ditch interception, and hidden culvert interception. Through technical and economic comparison and numerical simulation analysis of groundwater movement, the scheme for intercepting seepage and drainage of underground culverts has been determined. The implementation of the hidden culvert seepage interception and underground runoff control plan has significantly reduced the groundwater level in Baozitan Village, and the groundwater depth of typical farmers has decreased from 0.3 m～0.8 m before the control to below 2.5 m. The village′s waterlogging control has achieved significant results. The technology of underground runoff hidden culvert seepage control can provide reference for the treatment of groundwater in similar areas.
