Description
Изобретение относитс к подземному строительству , а именно к устройствам дл возведени обделок подземных выработок, тоннелей и т. п.The invention relates to underground construction, namely to devices for erecting lining of underground workings, tunnels, etc.
Известны устройства дл возведени монолитно-прессованной обделки подземных сооружений , включающие секционную опалубку.Devices are known for erecting a monolithic extruded lining of underground structures, including sectional formwork.
Однако в таких устройствах секционна опалубка может примен тьс только дл прессовапи материала обделки в направлении продольной оси тоннел .However, in such devices, sectional formwork can be used only for pressing the lining material in the direction of the longitudinal axis of the tunnel.
Цель изобретени - обеспечение прессовани материала обделки в радиальном направлении .The purpose of the invention is the provision of extrusion of the lining material in the radial direction.
Достигаетс она тем, что кажда секцн опалубки выполнена составной с шарнирно сочлененными между собой элементами, часть которых нонарно посредством общего щарнира св зана с приводами.It is achieved by the fact that each sectional formwork is made of composite elements with articulated articulations, some of which are nonarnately connected to the drives by means of a common joint.
На фиг. 1 изображено описываемое устройство дл подземных выработок кругового очертани в вертикаль 1ом осевом продольном разрезе; на фиг. 2 - разрез но А-Л на фиг. I, в положении дл транспортировки; на фиг. 3 - то же, в положении дл бетонировани ; на фиг. 4 - то же, в положении после окончани прессовани материала обделки; на фиг. 5 - устройство дл возведени обделки в выработке подковообразного очертани .FIG. 1 shows the described device for underground workings of circular outline in vertical with a 1st axial longitudinal section; in fig. 2 shows a section A-L in FIG. I, in position for transportation; in fig. 3 is the same in the position for concreting; in fig. 4 is the same in the position after the extrusion of the lining material is completed; in fig. 5 shows a device for erection of lining in the development of a horseshoe-shaped outline.
Устройство включает секцпонную опалубку / с шарнирно сочлененными между элементаЛП1 2, из которых чаеть элементов 3 попарно посредством общего щарнира 4 св зана с приводам - 5, н торцовую унлотнительную конструкцию 6.The device includes sectional formwork / with articulated joints between the element LP1 2, of which 3 elements are pairwise connected by means of a common joint 4 to the actuators - 5, on the end sealing structure 6.
Две пары элементов 3 (см. фиг. 2) св заны через шарниры е приводами. Однако кажда секци опалубки может выполн тьс и с другим количеством элементов, попарно св занных е прпводом. Дл выработок подковообразного очертани , когда лоток выработки бетонируете неодновременно со стенами п сводом , секци опалубки может быть незамкнутойTwo pairs of elements 3 (see Fig. 2) are connected via hinges with actuators. However, each formwork section can also be made with a different number of elements connected in pairs by an e-lead. For workings of a horseshoe-shaped outline, when the working tray is concreted non-simultaneously with the walls of the vault, the section of the formwork can be open
в нижней части.in the lower part.
При наименьшей значении угла между элементами 3 еекцн оналубки складываетс в положение (ем. фнг. 2) дл транснортнрованн At the smallest value of the angle between the elements of the 3, the onalubki’s folds are folded into a position (i.e. fng. 2) for transnationally
по выработке, а при наибольшем значении этогс угла принимает положение (см. фиг. 4), соответствующее проектному очертанию выработки .on the development, and at the highest value of the angle takes the position (see Fig. 4), corresponding to the design outline of development.
Бетонна смесь подаетс за опалубку, когдаConcrete mix is applied for formwork when
секци установлена в промежуточном положении (с.м. фиг. 3), выбираемом таким образом, чтобы при последующем положении (ем. фиг. 4) бетонна смесь унлотнилась по всему сечению обделки на 10-15% от первоначальБетонна смесь прессуетс поверхностью опалубки в радиальном направлении давлением , возникающим от увеличени наружных габаритных размеров секции опалубки при работе приводов секции опалубки.the section is installed in an intermediate position (cm. of fig. 3), chosen so that during the subsequent position (i use of fig. 4) the concrete mixture is compacted over the entire cross section of the lining by 10-15% of the original concrete mixture is pressed by the formwork surface in the radial the direction of pressure arising from an increase in the external overall dimensions of the formwork section during operation of the formwork section drives.
Торцовой зазор между стенами выработки и бетонируемой секцией опалубки закрываетс торцовой унлотиителыюй коиструкцией, передвигающейс вперед по мере возведени обделки.The end gap between the walls of the excavation and the concreted section of the formwork is closed by the end aperture co-moving, moving forward as the lining is erected.
