Abstract
Изобретение относитс к креплению горных выработок и позвол ет повысить качество закреплени трубчатого анкера В пробуренные шпуры (Ш) устанавливают анкерные трубы (AT) 1. Производ т закрепление в нем AT 1 путем пластического деформировани посредством перемещаемого в канале AT I гидроклинового устройства (ГКУ) 2. Пластическое деформирование AT I производ т с приданием ей конусности , расшир ющейс в сторону дна Ш путем изменени созданного в ГКУ 2 избыточного давлени от минимального при размещении ГКУ в устье Ш до максимального при размещении его в донной части Ш Перемещ,ение ГКУ 2 осуществл ют от усть ко дну Ш. При введении AT 1 в Ш м ожно оставл ть зазор между ее внутренним концом и дном Ш. При этом ГКУ 2 размещают одним концом в AT 1, другим в зазоре . Последний может быть р авным половине длины рабочей повер.хности ГКУ 2 После деформировани AT извлекают УкУ 2. Затем полость AT 1 заполн ют твердеющей массой. Далее осуществл ют нат жение анкера. 1 з.п.ф-лы, 5 ил. о iO (ЛThe invention relates to the fastening of mine workings and improves the quality of the securing of the tubular anchor. The drilled holes (W) install anchor pipes (AT) 1. The AT 1 is fixed therein by plastic deformation by means of a hydroclinic device (HCU) 2 moved in the AT I channel. The plastic deformation of AT I is carried out with a tapering it expanding towards the bottom of the Ш by changing the overpressure created in the CCU 2 from the minimum when the HCU is placed in the mouth of the Ø to the maximum when pa Placing it in the bottom part of the Ø Shift, moving GCU 2 is carried out from the head to the bottom of the Sh. When AT 1 is introduced into W, you can leave a gap between its inner end and the bottom of the Sh. At this, the GKU 2 is placed at one end in AT 1, the other in the gap. The latter may be equal to half the length of the working surface of the gas turbine unit 2. After deforming the AT, the VOC 2 is removed. Then the AT cavity 1 is filled with a hardening mass. Next, the anchor is tensioned. 1 hp ff, 5 ill. about iO (L
