Excerpt from Practical Shaft Sinking
The subject matter of this book was published as a series of articles in Mines and Minerals, during 1909 and 1910. It is reproduced, with some alterations and additions, through the courtesy of Mr. Rufus J. Foster, manager, and Mr. Eugene B. Wilson, editor of Mines and Minerals. The writer also wishes to acknowledge his indebtedness to Mr. H. H. Stock, who was editor of Mines and Minerals when most of the articles came out.
September, 1910.
Since the text of the first edition of "Practical Shaft Sinking" was written, cement grout has been used in several American shafts to cut off flows of water encountered in sinking, and its further use for this purpose will undoubtedly become more common. The writer, therefore, believes that a description of the methods used in grouting off flows of water in two of the city aqueduct shafts (Catskill Aqueduct Project) will make an interesting appendix. Such a description is given in Appendix A. It will be noted that in one of these shafts a stratum of loose and prevented the entire exclusion of the water by grouting alone, that a concrete lining provided with drain pipes was placed, and that the shaft was finally made entirely dry by grouting this lining.
Several of the city aqueduct shafts in Brooklyn and the lower east side of Manhattan Island were sunk through great depths of water-bearing sand by the pneumatic caisson process.
