Description
Нижние концы ножек 5 заход т в вырезы верхней стенки лежана 2, где они фиксируютс скошенными унорами 9. Стойки 3 могут быть также выполнены жесткими, без узлов податливости, из одного элемента, но об зательно должны иметь угловой изгиб.The lower ends of the legs 5 go into the notches of the upper wall of the bed 2, where they are fixed with oblique unors 9. The uprights 3 can also be made rigid, without nodes of compliance, from one element, but must necessarily have an angular bend.
Монтаж крепи осуществл етс в следуюш,ем пор дке: вначале укладываетс лежан 2, на него устанавливаютс заранее собранные из укосин 4 и ножек 5 стойки 3, затем заводитс верхн к 1 (при последней операции длипа стоек может быть изменена за счет замков податливости ).Mounting lining is carried out in the following order: first lie down 2, pre-assembled from strings 4 and legs 5 of rack 3 are installed on it, then winding up to 1 (during the last operation, the length of the racks can be changed by means of compliance locks).
При про влени х горного давлени срабатывают замки податливости: происходит проскальзыванне укосины 4 по ножке 5.When manifestations of rock pressure, the locks of compliance are triggered: there is a slip of the strut 4 along the leg 5.
В зоне опорного давлени под верхн к 1 можно нодводить прогон (вандрут), усиливающей крепь. На сопр жении с очистным забоем стойки рамы со стороны лавы демонтируют , после чего верхн к удерживаетс на вандруте . По проходе лавы вандрут убирают и крепь демонтируют.In the zone of the pressure below the top to 1, you can add a run (vandrute), reinforcing the lining. In conjunction with the clearing face, the legs of the frame on the lava side are dismounted, after which the upper frame is held on the vandrut. Along the lava aisle, the vandrut is removed and the supports are dismantled.
Данна конструкци замкнутой крепи позвол ет снизить на 80% трудоемкость монтажно-демонтажных работ и увеличить в 1,5 раза несущую способность без увеличени металлоемкости крепи.This design of closed lining allows reducing the labor intensity of assembly and dismantling works by 80% and increasing the bearing capacity by 1.5 times without increasing the metal intensity of the lining.
