AbstractAbout AuthorsReferences
The article considers the issue of the deviation of the boring head when drilling vertical wells, determining the real values of deviations from the vertical of wells, comparing the results with the permissible values specified in Russian and European documents, as well as studying the influence of deviations on the quality of work performed when solving various tasks of underground construction using the technology of jet cementation of soils. It is shown that the deviation of wells from the vertical is important only when installing vertical or horizontal anti-filtration curtains. When solving problems related to the strengthening of the soil mass with vertical soil-cement elements, as well as when installing pile foundations, the angle of deflection of wells is not of fundamental importance.
