Abstract
The utility model provides a six-shaft cement mixing method. A cement mixing wall is composed of a plurality of cement mixing methods which are vertically lapped with one another, and a plurality of cement mixing walls are lapped with one another and form a longer cement mixing wall. The cement mixing wall is characterized in that each cement mixing wall is composed of six vertical cement mixing methods, the six cement mixing methods are formed simultaneously and are positioned in the same plane, and adjacent cement mixing methods are lapped with each another. Due to the fact that the adjacent cement mixing walls are lapped with each other and the six cement mixing methods are formed simultaneously, seamless lapping is achieved, seams formed by the original single-shaft cement mixing methods or double-shaft cement mixing methods are reduced, water-stopping effect and construction efficiency are improved, amount of labor being used is reduced, and construction period is shortened more than two thirds.
