Изобретеиие относитс к горной промышленности , а именно к креплеиию горных выработок в уеловн х пучащих почв.The invention relates to the mining industry, in particular to the fastening of the mine workings in the man-made, pulling soils.
Известна металлическа замкнута крепь дл горных выработок, состо ща из отдельных сегментов спецпрофил , податливо соединенных между собой при помощи хомутов в замкнутый контур 1.Known closed metal support for mine workings, consisting of individual special profile segments, malleablely interconnected by means of clamps in closed loop 1.
Недостатком указанной крепи вл етс ее неустойчнвость в услови х пучапщх почв, так как обратный свод податливо св зан с прилегающими сегментами и при преобладающем давлении со стороны почвы не обеспечивает посто нного сопротивлени податливости крепи . Кроме того, при возведении крепи сначала ведут укладку сегмента обратного свода, затем боковых и верхнего сегментов. Работы осуществл ютс в незакрснлеином пространстве , что небезопасно.The disadvantage of this support is its instability under the conditions of soils, since the return arch is flexibly connected with the adjacent segments and with the prevailing pressure from the soil does not provide permanent resistance to the support of the supports. In addition, during the erection of the lining, they first lay down the segment of the return vault, then the side and upper segments. Work is carried out in an open space, which is unsafe.
Известна также замкнута металлическа арочна крепь, состо и1,а из сводчатого верхн ка , ножек и обратного свода. Последние соединены между собой замками податливости , в которых имеютс угловые звень , хомуты и гайки 2.Also known is the closed metal arch support, consisting of 1, and from the vaulted top, legs and invert. The latter are interconnected by ductility locks, in which there are corner links, clamps and nuts 2.
Недостатки известной крепи следующие: крепь не обладает достаточной надежностью; не обеспечиваетс безоиасность возведени крепи вследствие того, что первоначально производитс укладка обратного свода в иезакреплсппом пространстве; снижаютс темпы проведени выработок, так как первоначальные работы по сооружению обратного свода не мехапизированы.The disadvantages of the well-known lining are as follows: the lining is not sufficiently reliable; the safety of the erection of the lining is not ensured due to the fact that the inset is initially laid in the arch of space; the rate of workings is reduced, as the initial work on the construction of the return arch is not mechanized.
Целью изобретени вл етс иовьииеиие надежности работы крени в услови х iiy4anuix почв, безопасности ее возведени и ускорение темпов проведени горных выработок. Это достигаетс тем, что обратный свод расположен внутри контура крепп, причем между обратным сводом и ножками имеютс зазоры, а кажда ножка еиабжеиа уиором дл ограничени податливости обратного свода.The aim of the invention is to improve the reliability of the work of the roll in the conditions of soil iiy4anuix, the safety of its erection and the acceleration of the pace of mining workings. This is achieved by the fact that the return arch is located inside the contour of the crepe, and there are gaps between the return arch and the legs, and each leg is equipped with a diaphragm for limiting the flexibility of the return arch.
На фиг. 1 показана предлагаема замкнута металлическа арочна крепь; на фнг. 2 - узел креплеип обратного свода к ножке .FIG. Figure 1 shows the proposed closed metal arch support; on fng. 2 - knot for fixing the invert to the leg.
Замкнута металлическа арочна крепь состоит из сводчатого верхи ка, ножек, обратного свода и замков податливости, в которых имеютс угловые звень , хомуты и гайки . Сводчатый верхн к 1 податливо соедииен с ножками 2. Внутри контура крепи расположен обратный свод 3 с зазорами между ним и ножками, который соедииеп ограпичеиио-податливо с ножками при помощи угловых звеиьев 4 и хомутов 5 с гайками. На ножках наход тс упоры 6, предиазпачениые дл ограничени податливости обратного свода.An enclosed metal arch support consists of a vaulted top, legs, invert, and supple locks, which have corner links, clamps, and nuts. The vaulted upper to 1 compliantly connects with the legs 2. Inside the contour of the support there is an inverse arch 3 with gaps between it and the legs, which is connected with the legs by means of angular stars 4 and 5 clamps with nuts. There are stops 6 on the legs, predisposed to limit the compliance of the invert.
Крепь работает следующим образом.The support works as follows.
При пучении почвы обратный свод 3 стремитс выпр митьс и подаетс по угловым звеиь м 4 до упора в но/кг п 2, которыс плогио прилегают к боковым породами. В случае дальнейшего пучени почвы обратный свод 3 вместе с угловыми звень ми 4 подаетс вверх по ножкам 2 до упоров 6.When the soil heals, the return arch 3 tends to be straightened and fed along the angular stars 4 m up to the stop in no / kg n 2, which, adjacent to the lateral rocks, are attached. In the case of a further soil heave, the return arch 3, together with the corner links 4, is fed up along the legs 2 to the stops 6.
