锥探灌浆技术治理蚁穴通道系统

位于堤身饱气带中的蚁穴系统与干缩裂缝和孔隙连通后。将形成较大范围的透水体。注入的宾汉浆液主要以竖向渗透和沿孔道流动的形式运动，只有当竖向渗透使土体达到饱和后，才会沿横向产生单向平面渗流．完整井情况下的锥探灌浆，其渗入型式可按单向渠道网络模型下的竖向渗流形式来考虑．蚁害治理工作中。必须在充分掌握蚁穴发育规律的基础上。合理设计锥孔；施工时要加强对灌浆流量、灌浆压力、横向水平位移和裂缝开展宽度等的综合控制。同时要做好质量检测工作，以确保施工质量。达到消除蚁害、加固堤坝的目的．

Use of awl exploration grouting technique to eliminate ant-nest systems in dykes

It was founded that a large permeable soil-body would be formed when the ant-nest system located in an air-saturated zone of dyke body had been connected with desiccation cracks and cavities, and the cement grout penetrated usually in vertical directions. The grout of awl exploration grouting began a horizontal penetration only after the vertically penetrated soil-body had become saturated. For a full well excavated down to the impervious stratum, the penetrating pattern could be considered as a model of canal network according to the seepage laws of vertical flow. During managing ant risks, special precautions should be taken to the pattern of ant-nest development and rational design of awl grouting holes. A synthetic control has to be made for grouting flow and pressure, transversal horizontal displacements, opening de cracks, etc. At the same time, testing work must be well done to insure the construction quality for the purposes of eliminating ant calamities and strengthening dyke (structures.)
