Abstract
Изобретение относитс к горной промышленности Цель повышение прочности закреплени анкера в шпуре и обеспечение упрочнени прилегающего горного массива одновременно с расклиниванием анкера . Анкер содержит трубчатый стержень (ТС) 1 с аксиальной продольной складкой (ПС) 2. Внутренний конец ТС 1 загерметизирован . конец 3 выполнен без складки открытым с торца и в нем установлен полый хвостовик 4 с обратным клапаном 5. Внутренний конец ТС 1 изогнут в сторону хвостовика 4 и выполнен в ви де клина 10. Последний размещен внутри ПС 2, котора имеет ослабленное сечение 8 К поверхности сечени 8 жестко прикреплен острием шип 9, ориентированный перпендикул рно продольной оси анкера. На ТС 1 с упором в опорную плиту 6 надето уплотнительное кольцо 7. Собранный анкер ввод т в пробуренный шпур и через рукав 12 нагнетают в ТС 1 упрочн ющий состав. Под давлением состава ПС 2 распр мл етс , ТС 1 несколько укорачиваетс , плита 6 прижимаетс к поверхности горной породы. При распр млении ПС 2 клин 10 внедр етс в стенки . После полного распр млени ПС 2 шип 9 прокалывает стенку ТС 1 в ослабленном сечении 8. Через образовавшеес отверстие прочн ю- щий состав нагнетаетс в шпур и трещины породного массива. 4 ил. U (ЛFIELD OF THE INVENTION The invention relates to the mining industry. The purpose of increasing the strength of securing an anchor in a hole and ensuring the strengthening of the adjacent rock mass simultaneously with the wedging of the anchor. The anchor contains a tubular rod (TS) 1 with an axial longitudinal fold (PS) 2. The inner end of TS 1 is sealed. The end 3 is made without a fold open from the end and has a hollow shank 4 with a check valve 5. The inner end of TC 1 is bent toward the shank 4 and is shown as a wedge 10. The latter is placed inside PS 2, which has a weakened section of 8 K Section 8 is rigidly attached with a spike 9, oriented perpendicular to the longitudinal axis of the anchor. On TS 1 with an emphasis on the base plate 6, a sealing ring 7 is put on. The assembled anchor is inserted into the drilled hole and, through sleeve 12, is injected into TS 1 a reinforcing composition. Under pressure, the PS 2 composition is straightened, TS 1 is somewhat shortened, plate 6 is pressed against the surface of the rock. When PS 2 is opened, the wedge 10 is inserted into the walls. After PS 2 has been completely straightened, spike 9 pierces the wall of TC 1 in a weakened section 8. Through the hole formed, a strong composition is injected into the hole and cracks of the rock mass. 4 il. U (L
