Abstract
Изобретение относитс к подземному строительству и может быть использовано при сооружении калоттной прорези односводчатой станции метрополитена в неустойчивых грунтах, требующих посто нного поддержани кровли выработки, с возведением свода в виде сборной железобетонной обделки. Цель - расширение области применени и механизаци процесса перемещени крепи. На несущей раме 5 с опорными стойками 9 установлены с возможностью выдвижени шандоры 10. Под рамой 5 установлена арочна опора 1, соединенна с рамой посредством телескопических вертикальных св зей. Телескопические св зи установлены в выполненных в опоре 1 направл ющих 6. Кажда телескопическа св зь выполнена в виде гидроцилиндра /ГЦ/ 7 и шарнирно прикрепленной к его штоку т ги 8. Корпуса ГЦ 7 шарнирно закреплены на опоре 1, а т ги 8 - на раме 5. С помощью подъемного устройства поднимают опору 1, регулиру ГЦ 7 и т гами 8 положение рамы 5. Вместе с опорой 1 поднимаетс лежащий на ней набор блоков, соответствующий форме свода выработки, и прижимаетс к нижней поверхности шандор 10. Выдвига сь к забою, шандор 10 выходит из пространства над укладываемым блоком, перекрыва вновь образованный участок свода. 1 з.п.ф-лы. 6 ил.The invention relates to underground construction and can be used in the construction of a marsh pit of a single vaulted metro station in unstable soils that require constant maintenance of roofing, with the construction of a vault in the form of precast concrete lining. The goal is to expand the field of application and mechanize the process of moving the lining. On the carrier frame 5 with support posts 9, the overpasses 10 are installed with the possibility of extension. Under the frame 5 there is an arch support 1, connected to the frame by means of telescopic vertical links. Telescopic links are installed in guides 6 made in support 1. Each telescopic connection is made in the form of a hydraulic cylinder / HZ / 7 and a hinge 8 hinged to its rod 8. HZ housings 7 are hinged on support 1 and 8 are on frame 5. With the help of a lifting device, support 1 is raised, adjusting HZ 7 and t 8 to the position of frame 5. Together with support 1, a set of blocks lying on it, corresponding to the shape of the roof, is pressed and sandwich 10 is pressed to the bottom surface. , shandor 10 emerges from space above stacking my block, overlapping the newly formed part of the arch. 1 hp ff. 6 Il.
