Essay

This thesis is devoted to the questions of calculations and projection of boring casings and of technology of theirs assembling in construction of shafts and bore-holes of big diameters.On the basis of performed researches of state of tense-strain (STS) of pipe in different stages of lining construction process theoretical bases of projecting of boring casings and of their construction's elements (demountable band, steel bottom) were engineered.The functional dependences of force influence on a de-formation of an upper butt of a pipe of a boring casing in conditions of construction during its getting down on an assembly beam were found. And the character of in-fluence of forces from boring casing on STS in a zone of assembly window was re-searched.As the result the using of a thrust appliance during the construction per-formance is offered. It allows to increase a bearing capability of existent construction of column in 4-6 times. And taking the using of them into account of project calcula-tions letsto reduce a metal content in casing pipes on 10 - 30%.
