| Abstract: | In the project of the shaft surface pre grouting of the auxiliary well of XD 2 well, by using the new technique of clay cement mud pre grouting, the grouting construction mission was fulfilled with high efficiency, and an All China record of the depth of shaft surface pre grouting, long grouting interval and high efficiency of drilling grouting was created. Explorations and experiments on such technical problems like the hole making of deep shaft grouting hole, directional drilling, mud making technology, grouting technology and the selection of grouting parameters were made and rather satisfactory results were obtained, as providing useful technical data for similar grouting projects. |
