METHOD FOR CONSTRUCTING A THREE-SPAN SUBWAY STATION OF AN OPEN METHOD OF PERFORMING WORKS WITH A LATERAL ARRANGEMENT OF PASSENGER PLATFORMS AND A DOUBLE-TRACK STILL TUNNEL

FIELD: construction.SUBSTANCE: invention relates to construction of tunnels, in particular to a method of constructing subway stations of open-pit method for production of works with lateral arrangement of platforms. Method of construction of three-span metro station of open method of works with lateral arrangement of passenger platforms and with double-track tunnels includes erection of central station tunnel from prefabricated tubing when driving double-track tunnels. Tubing rings made with rectangular cross-section and outer diameter equal to the diameter of the tunnels are assembled without seam ligation; lateral halls are erected by way of soil development. Concrete monolithic reinforced concrete walls are arranged in the middle station tunnel. Then monolithic reinforced concrete walls are concreted, located on the side of side halls, at that, tubing of vaulted and tray part of central station tunnel remain in concrete concretes of reinforced concrete walls. Main load-bearing structures of the station, the floor covering and covering elements of the station are concretered, and the tray plate of the middle station tunnel with a flat outer surface, the width of which provides arrangement of two paths, concrements simultaneously with the base under the path. In load-carrying monolithic reinforced concrete walls, temporary filling tubing is dismantled at the openings locations, monolith frames for framing openings are reinforced and concreted; then the apertures are equipped with sliding doors.EFFECT: technical result consists in reducing the cost of erecting a plant, improving manufacturability, speed of construction and safety of operation.1 cl, 2 dwg Изобретение относится к области строительства тоннелей, в частности к способу строительства станций метрополитена колонного типа открытого способа производства работ с боковым расположением платформ. Способ возведения трехпролетной станции метрополитена открытого способа производства работ с боковым расположением пассажирских платформ и с двухпутным перегонным тоннелем включает возведение среднего станционного тоннеля из сборных тюбингов при проходке перегонного двухпутного тоннеля. Тюбинговые кольца, выполненные с прямоугольным сечением и с наружным диаметром, равным диаметру перегонных тоннелей, монтируют без перевязки швов, затем возводят боковые залы путем разработки грунта. Бетонируют несущие монолитные железобетонные стены, расположенные в среднем станционном тоннеле. После чего бетонируют несущие м
