METHOD FOR ERECTION OF THREE-VAULT SUBWAY STATION OF CLOSED METHOD FOR PRODUCTION OF PYLON TYPE WORKS

摘要

FIELD: construction.;SUBSTANCE: invention relates to construction and can be used in construction of underground stations erected by closed method of works. According to the method, monolithic reinforced concrete frame posts are concreted within the station tunnels and on the sides of the proposed passages for passengers. After reinforcement strength of posts in formed in lining of niche tunnels, beams framing beams are installed, at first lower, then upper ones. Gap between beams and support parts of permanent structures of tunnels is filled with high-quality non-shrinking solution. In order to combine metal beams and with steel tubings in a single combined section space between tubings and beams is filled with concrete, inner volume of beams is filled with cement-sand solution. Temporary filling tubings are dismantled under the framing protection of the openings. After dismantling of temporary filling tubings, monolithic passages for passage of passengers with reinforced upper arch are built between side tunnels and middle station tunnel. After the end of construction of station lining in side tunnels passenger platforms and rail track structures are built, in the middle station tunnel passenger platform structures are constructed.;EFFECT: improved manufacturability of creation of openings for passage of passengers when erecting three-terminal vault stations of deep pylon type, increased speed of construction, as well as reduced possible deposits of day surface.;1 cl, 3 dwg
