Description
Известны передвижные опалубки дл параллельного производства работ при проходке шахтных стволов, состо щие из двух полуцилиндров , каркаса,сегментов, форкопфов, винтовых домкратов и опорных колец.Mobile formwork for parallel work when sinking shaft shafts are known, consisting of two half-cylinders, a framework, segments, forcopes, screw jacks and support rings.
Описываема передвижна опалубка отличаетс от известных тем, что она выполнена с подвижным относительно опалубки каркасом, снабженным опорным кольцом и состо щим из стоек, колец жесткости, подвесного приспособлени , а также домкратов, штоки которых св заны с упорами, укрепленными на полуцилиндрах. Такое выполнение опалубки позвол ет ускорить производство работ при параллельном способе проходки шахтных стволов.The described mobile formwork differs from the known ones in that it is made with a frame that is movable relative to the formwork, equipped with a support ring and consisting of racks, stiffening rings, hanging device, as well as jacks, the rods of which are connected to stops supported on semi-cylinders. This formwork makes it possible to accelerate the production of works with a parallel method of penetrating the shaft.
На фиг. 1 изображена описываема опалубка в общем виде; на фиг. 2 - деталь соединени элементов опалубки в двух проекци х.FIG. 1 shows the described formwork in general; in fig. 2 is a detail of the connection of the formwork elements in two projections.
Опалубка состоит из отдельных жестко соединенных секций, образующих металлический цилиндр. Цилиндр имеет два диаметрально рас положенных зазора , которые во врем бетонировани закрыты сегментами 2, шарнирно св занными с опалубкой. Зазоры служат дл создани хода опалубки во врем ее отрыва от бетона при помощи форкопфов 3. Дл обеспечени посто нства формы опалубки предусмотрен жесткий подвижной каркас 4, на который опираетс опалубка при помощи упоров 5.The formwork consists of separate rigidly connected sections, forming a metal cylinder. The cylinder has two diametrically spaced gaps that are closed during concreting with segments 2 pivotally connected to the formwork. The gaps serve to create the formwork course during its separation from concrete with the help of a porkof 3. To ensure the form constancy of the formwork, a rigid movable frame 4 is provided, on which the formwork is supported using the stops 5.
Пикотаж осуществл етс при помощи пакетов, состо щих из отдельных дерев нных брусков 6, которые уложены на опорное кольцо 7. Последнее жестко св зано с подвижным каркасом 4 стойками 8. Дл образовани зазоров между опалубкой и опорным кольцом применены домкраты 9.The pictogram is carried out with the help of packages consisting of individual wooden bars 6, which are placed on the support ring 7. The latter is rigidly connected to the movable carcass 4 racks 8. The jacks 9 are used to form the gaps between the formwork and the support ring.
В положении / после бетонировани домкраты опущены, и опалубка прижимает пикотажные пакеты к опорному кольцу. Когда сделан отход на следующую заходку, жесткий каркас с опорным кольцом опускаетс д.о ynopai, и домкраты выдвигаютс в рабочее положение //. Затем пикотажные пакеты, которые схватились с бетоном, отрываютс и поко тс на юпорном кольце. После этого при помощи винтов 10 открываетс , ceRMgi T 2; и при помощи форкопфов 3 опалубка отрываетс от бетона и опускаетс на следующую заходку.In the position / after concreting, the jacks are lowered, and the formwork presses the plastic bags against the support ring. When the departure is made to the next stop, the rigid frame with the support ring is lowered to the bore ynopai, and the jacks are moved to the working position //. Then, the pouches that grappled with the concrete are torn off and resting on the junction ring. After that with the help of screws 10 it opens, ceRMgi T 2; and with the help of forcopophones 3, the formwork is detached from the concrete and lowered to the next stopping.
Когда ,dtt0plHioe кольцо отцентрировано и произведен пикотаж, при помощи домкратов опалубка опускаетс на опорное кольцо, и приступают к бетонированию ствола.When the dtt0plHioe ring is centered and pikotage is made, with the help of jacks, the formwork is lowered onto the support ring, and the concreting of the trunk is started.
В заключении Центрального научно-исследовательского института Подземщахтострой отмечаетс , что применение жесткого подвижного каркаса дл обеспечени определенной формы .опалубки оригинально, и он может быть совместно с передвижной опалубкой использован при проходках стволов шахт.At the conclusion of the Central Research Institute Podzemschachtostroy, it is noted that the use of a rigid movable frame to provide a certain form of the formwork is original, and it can be used in conjunction with mobile formwork for the penetration of shafts.
Предмет изобретени Subject invention
Передвижна опалубка дл параллельного производства работ при проходке щахтных стволов, состо ща из двух полуцилиндров, сегментов , распорных винтов и форкопфов, отличающа с тем, что, с целью ускорени и улучщени условий работ, она выполнена с подвижным относительно опалубки каркасом, снабженным опорным кольцом и состо щим из стоек, колец жесткости, подвесного приспособлени и домкратов, щтоки которых св заны с упорами, укрепленными на полу цилиндрах .Mobile formwork for parallel work when driving shafts, consisting of two half-cylinders, segments, spacer screws and forcopes, characterized in that, in order to accelerate and improve working conditions, it is made with a frame that is movable relative to the formwork and equipped with a support ring and consisting of racks, stiffening rings, hanging device and jacks, the rods of which are associated with stops, cylinders fixed to the floor.
