Description
На фиг. 1 схематически представлена разметка блоков и шпуров в забое, вид в плане; на фиг. 2 - забой, вид спереди; на фит. 3 изображен стеновой блок в разрезе .FIG. 1 shows schematically the marking of blocks and holes in the bottomhole, plan view; in fig. 2 - face, front view; on fit. 3 shows a wall block section.
Способ осуществл ют следующим образом .The method is carried out as follows.
В забое (по кровле) производ т разметку блоков 1 и вертикальных шпуров 2, которые затем пробуривают с опережением на несколько циклов. На уровне подошвы забо выполн ют горизонтальный пропил 3, из щели которого в шпур 2 устанавливают армирующий стержень 4 с голозкой 5 на нижнем конце и резьбой на верхнем его конце. Из щели горизонтального пропила 3 на головку 5 стержн 4 насаживают разрезную шайбу 6. Полости шпуров заполн ют укрепл ющим раствором 7. Носле чего на верхний конец армирующего стержн 4 насаживают опорную шайбу 8, гайку 9 и нроизвод т обжатие блока. Затем осуществл ют вертикальный и тыльный пропил 10 и извлекают блок до затвердевани укрепл ющего раствора.In the bottom (on the roof), blocks 1 and vertical bore holes 2 are marked, which are then drilled several times ahead. At the level of the bottom, horizontal cutting is made 3, from the slot of which a reinforcing rod 4 is installed into the hole 2 with a hollow 5 at the lower end and a thread at its upper end.
