Distributing control point used of straight closed traverse and using of distance measurement polar coordinates and near distance high degree level measuring method to do deformation measuring for the plugging water curtain wall.

The construction method of high pressure spray grouting technology in seepage prevention curtain against municipal flood control dykes in cold region was presented.

Formed by the forced mixing of proportioned cement mortar and foundation soil by special machine deep in the foundation,the water-stopping curtain wall of soil-cement pile can improve the stability of the foundation slope and performance of anti-seepage,thus reaches the objectives of stopping water and retaining soil.

The paper introduces the characteristics,the application scope,the technological principle and the effects of the original construction technology of using integral hydraulic steel sheet pile curtain in shaft surface soil\'s passing through quicksand, and it has an important guiding significance for engineering practice.
