摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 construction underground, and can be used in the construction of metro stations u043fu0438u043bu043eu043du043du043eu0433u043e type underground way. the purpose of u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 - increased safety, reduced labour intensity and material consumption. in the prefabricated concrete blocks 1 adjacent tunnels 2 and 3 u043fu0440u043eu0438u0437u0432u043eu0434u00a0u0442 drilling u0448u043fu0443u0440u043eu0432 in cross-section u0441u043eu043eu0440u0443u0436u0430u0435u043cu043eu0433u043e pole (p) 4.u0432u0432u043eu0434u00a0u0442 in u0448u043fu0443u0440u044b metal rods (ms) 5 with the release of their ends on both sides of a u0441u0435u0447u0435u043du0438u00a0 p 4 at its design width. then u043fu0440u043eu0438u0437u0432u043eu0434u00a0u0442 u0446u0435u043cu0435u043du0442u0430u0446u0438u044e soil p 4 through u0448u043fu0443u0440u044b. after that, establish the framework and not the cement depot u0431u0435u0442u043eu043du0438u0440u0443u044eu0442 to project the width w 4 between the circuit and u043eu0431u0434u0435u043bu043au043eu0439 by u0442u043eu043du043du0435u043bu00a0.in u0430u0440u043cu0430u0442u0443u0440u043du043eu043c frames having switch elements u0434u043bu00a0 u0441u043eu0435u0434u0438u043du0435u043du0438u00a0 with monolithic u0431u0430u043bu043au043eu0439 7, u043fu0435u0440u0435u043au0440u044bu0432u0430u044eu0449u0435u0439 doorway. u0434u043bu00a0 u0443u043cu0435u043du044cu0448u0435u043du0438u00a0 width w 4 part of the ms 5 are in tubes and after u0431u0435u0442u043eu043du0438u0440u043eu0432u0430u043du0438u00a0 p 4 u043fu0440u043eu0438u0437u0432u043eu0434u00a0u0442 prior u043du0430u043fu0440u00a0u0436u0435u043du0438u0435 ms 5. 2 z. s - lu, 5).
