Description

поэтому при продольном нагружении анкера величина бокового распора втулок в стенки шпура тем больше, чем выше нагрузка . Увеличение снеплени  анкера с массивом обусловлено также тем, что коэффициент трени  дл  фрикционной пары резина- порода в 2-3 раза выше, чем у пары сталь - порода. Гофрированна  поверхность придает анкеру дополнительную поперечную жесткость, а также устран ет возможность проскальзывани  трубы во втулках при воздействии на крепь интенсивных динамических нагрузок. Упруга  заделка анкера по всей длиие шпура повышает сейсмостойкость системы крепь - порода. Нова  конструкци  анкера также может быть эффективно использована дл  закренлени  в бетонных фундаментах различных вибромеханизмов.therefore, with the longitudinal loading of the anchor, the amount of lateral thrust of the sleeves into the walls of the hole is greater, the higher the load. The increase in anchor clearance with an array is also due to the fact that the friction coefficient for a friction pair of rubber-rock is 2-3 times higher than that of a steel-rock pair. The corrugated surface gives the anchor additional lateral rigidity, and also eliminates the possibility of pipe slippage in the sleeves when the lining is subjected to intense dynamic loads. Elastic sealing of the anchor along the entire length of the hole increases the seismic resistance of the support-rock system. A new anchor design can also be effectively used to stake various vibromechanisms in concrete foundations.

шпура Формула изобретени  Штангова  крепь горных выработок, включаюша  трубчатый анкер, закрепл емый в шпуре посредством взрывани  размешенного внутри трубы зар да взрывчатого вешества, и втулки из эластичного материала , расположена вдоль анкера с интервалом , отличаюша с  тем, что, с целью увеличени  несушей способности крепи в скальных породах путем повышени  сцеплени  с ними, втулки закреплены на наружной поверхности трубы и снабжены продольными направл юц ими ребрами дл  центрировани  трубы в шпуре, которые расположены снаружи втулок. Источники информации, прин тые во внимание при экспертизе 1.Авторское свидетельство СССР № 362927, кл. Е 21 D 21/00, 1973. Formula of the invention Shank support for mine workings, including a tubular anchor fixed in the hole by blasting the explosive charge placed inside the pipe, and elastic material sleeves, are located along the anchor at intervals that differ from the in rocks by increasing adhesion with them, the bushings are fixed on the outer surface of the pipe and provided with longitudinal directions with ribs for centering the pipe in the hole, which are located at the front and bushings.
