Abstract

Локально-закрепляемый, саморезный, деформируемый, пустотелый анкерный болт оснащен одним или несколькими промежуточными локальными анкерами 16A, по обе стороны каждого из которых расположены относительно удлиняемые сегменты тела болта 14A, 14B. После подачи раствора через полую внутреннюю часть анкерного болта, расположенного в просверленное отверстие, каждый анкер 16A фиксирует болт в толще породы, при этом смежные гладкие сегменты тела болта 14A, 14B могут деформироваться и даже компенсировать растрескивание горных пород. Участки локальных анкеров могут иметь относительно малую длину по сравнению с сегментами тела болта. Один или несколько промежуточных анкеров 16A могут быть образованы с помощью соединительного патрубка, соединяющего смежные части болта вместе, и/или с помощью профилирования болта и/или отдельно устанавливаемого анкера. Располагаемый глубже всего в отверстии конец анкерного болта представляет собой сверлильный наконечник или может быть выполнен по ее образцу. Сверлильный наконечник может выполнять две функции: сверлить отверстие и служить в качестве внутреннего анкера болта.
