| Abstract: | Equipment well should be built under the pocket floor for the installation of monitoring equipments, while sandboils and waterspouts often occur in the construction and running process because of lax sealing. The paper introduces the system design of grouting cementing for the well under pocket floor and the construction process; discusses the grouting pressure of lateral extrusion grouting, water-cement ratio and grouting measures and analyzes the grouting principle and effects. |

| Keywords: | foundation treatment curtain grouting water shutoff sandboils and waterspouts well under gate base reservoir |
