Abstract
Изобретение относитс к горному делу. Цель - создание спиральной штрабы в стенке скважины, пробуренной в прочных грунтах или бетоне. Устройство дл сооружени скважины под винтовой анкер способом раскатки включает вал (В) 1 с эксцентриковыми развернутыми шейками. На последних установлены цилиндрические катки (К) 3 с возможностью обкатывани по стенке скважины (С). На поверхности К 3 закреплены спиральные ребра 4, армированные твердым сплавом или алмазами 5. Спиральные ребра 4 направлены в сторону вращени К 3 вокруг своей оси. Дл соединени К 3 между собой имеютс соединительные муфты 6 - кулачковые или резиновые. При создании спиральной штрабы в стенке С в нее ввод т устройство и вращают В 1. При этом К 3 обеспечивают подачу устройства внутрь С. Во врем подачи ребра 4 внедр ютс в стенку С и выдалбливают в ней винтовую штрабу. Образующийс штыб удал етс подачей воздуха через отверстие 7 в В 1. Обратную подачу производ т путем изменени вращени В 1. Затем в С с образованной в ней спиральной штрабой ввинчивают анкерный стержень, имеющий винтовую резьбу. 1 з.п. ф-лы, 2 ил.The invention relates to mining. The goal is to create spiral pitch in the wall of a well drilled in strong soils or concrete. A device for constructing a well under a screw anchor using the method of rolling includes a shaft (B) 1 with eccentric necks unfolded. On the latter, cylindrical rollers (K) 3 are installed with the possibility of rolling on the well wall (C). Spiral ribs 4 reinforced with hard alloy or diamonds 5 are fixed on the K 3 surface. Spiral ribs 4 are directed in the direction of rotation K 3 around their axis. For the connection K 3 between them there are connecting sleeves 6 - cam or rubber. When creating spiral pitch in the wall C, the device is inserted into it and rotated in 1. In this case, K 3 ensures that the device is fed inside C. During the feed, the ribs 4 are inserted into the wall C and hollowed in it with a screw penalty. The resulting pin is removed by supplying air through the 7 V hole. 1. The reverse flow is made by changing the rotation B 1. Then, an anchor rod having a screw thread is screwed into C with the spiral pin formed in it. 1 hp f-ly, 2 ill.
