悬挂式高压摆喷垂直截渗技术在洪泽湖大堤除险加固工程中的应用

Application of suspended high-pressure swing-jetting vertical seepagecutting technique in the Risk Removal and Reinforcement Project of Hongze Lake Levee

高压喷射灌浆是一种提高堤防抗渗性和稳定性的常用工程措施,属于隐蔽工程,灌浆效果直接影响工程质量和建筑物安全,其工程质量管理至关重要。本文以洪泽湖大堤除险加固工程为例,探讨总结了悬挂式高压摆喷防渗处理技术施工工艺及施工时的质量控制要点。同时在常规检测手段的基础上,综合探地雷达法、高密度地震映像法、声波法等检测方法对灌浆效果进行检测,有效确保了工程质量,可为同类工程提供借鉴和参考。

High pressure jet grouting is one of the common engineering measures to improve the impermeability and stability of embankment,which belongs to concealed project.The grouting effect directly affects the engineering quality and building safety.The engineering quality management is very important.The Risk Removal and Reinforcement Project of Hongze Lake levee is adopted as an example in the paper.The construction technology and construction quality control points of suspended high-pressure swing jet grouting anti-seepage treatment technology are discussed and summarized.Meanwhile,the grouting effect is detected by ground penetrating radar method,high-density seismic imaging method,acoustic wave method and other detection methods on the basis of conventional detection methods,thereby effectively ensuring the engineering quality and providing reference for similar projects.
