.Изобретение относитс к способам установки железобетонной анкерной крепи в горных выработках.The invention relates to methods for installing reinforced concrete anchor in mine workings.
Известен способ установки железобетонной анкерной крепи, включающий бурение шпуров, заполнение их бетоном при помощи пневмонагнетател или растворонасоса и установку в них анкеров 13.There is a method of installing reinforced anchor lining, including drilling holes, filling them with concrete using a pneumatic pressure charger or mortar pump and installing anchors in them 13.
Недостаток такого способа состоит в том, что при бурении образуетс пыль, загр зн юща воздух, а также в использовании дл бетона в качестве заполнител строительных материалов .The disadvantage of this method is that during the drilling process dust is generated that pollutes the air, and also is used for concrete as a filler for building materials.
Известен также другой способ установки железобетонной анкерной крепи, включающий бурение шпуров, заполнение их бетонной смесью из инертного заполнител , в жущего и воды, которую приготавливают после окончани бурени каждого шпура, и введение в наполненные бетоном шпуры анкеров12}.Another method of installing reinforced concrete anchors is also known, including drilling holes, filling them with an inert aggregate concrete mixture and water, which is prepared after each drill hole is finished drilling, and introducing anchors into the concrete-filled holes of boreholes 12}.
Недостаток такого способа состоит в расчете строительных материалов дл инертного заполнител , удорожающего крепь, а также в запыленности воздуха при бурении шпуров под анкеры .The disadvantage of this method is in the calculation of building materials for an inert aggregate, which is more expensive to fix, and also in the dustiness of the air when drilling holes for anchors.
Цель изобретени - снижение затрат на крепление и улучшение условий труда.The purpose of the invention is to reduce the cost of fixing and improving working conditions.
Цель достигаетс тем, что буровую .мелочь при бурении шпуров направл ют посредством шнека в камеру-смеситель дл использовани в процессе приготовлени бетонной смеси в качестве инертного заполнител .The goal is achieved in that the drill bit is drilled into the mixing chamber by means of an auger into the mixing chamber for use in the preparation of the concrete mix as an inert aggregate.
На чертеже изображена схема установки железобетонной анкерной крепи..The drawing shows a diagram of the installation of reinforced concrete anchors ..
Железобетонную анкерную крепь устанавливают следующим образом.Reinforced anchor lining set as follows.
Дл закреплени кровли бур т шпур To secure the roof of the drill hole
