METHOD OF CONSTRUCTING TUNNELS IN RAILWAY DAM FOUNDATION

摘要

the invention can be used in the construction of tunnels and pipes in u043eu0441u043du043eu0432u0430u043du0438u00a0 mounds of railways and roads. the decline in employment in the construction and construction materials u0440u0438u0430u043bu043eu0435u043cu043au043eu0441u0442u0438 u0442u043eu043du043du0435u043bu00a0 under mounds railroad.with the two sides embankment 1 u043fu0440u043eu0438u0437u0432u043eu0434u00a0u0442 u0437u0430u0431u0438u0432u043au0443 u0448u043fu0443u043du0442u043eu0432u044bu0445 elements u043eu0433u0440u0430u0436u0434u0435u043du0438u00a0 4, the upper ends of which u0441u043eu0435u0434u0438u043du00a0u044eu0442 flexible u0442u00a0u0436u0430u043cu0438 through prisms 7, u043fu0440u043eu0445u043eu0434u00a0u0449u0438u043cu0438 ballast 5. as u0443u0434u0430u043bu0435u043du0438u00a0 soil and u0443u0433u043bu0443u0431u043bu0435u043du0438u00a0 chambers 2 and 3 u043fu0440u043eu0438u0437u0432u043eu0434u00a0u0442 u043du0430u0442u00a0u0436u0435u043du0438u0435 flexible u0442u00a0u0436u0435u0439 7, which prevents deformation of the u0448u043fu0443u043du0442u043eu0432u044bu0445 elements 4.at the age of u043eu0441u043du043eu0432u0430u043du0438u00a0 u0442u043eu043du043du0435u043bu00a0 1 in the front working chamber 2, making the hard wall, in the lower section of the u0442u043eu043du043du0435u043bu00a0 and u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u044eu0442 their regular convocation u043fu0440u043eu0434u0430u0432u043bu0438u0432u0430 we through the u0434u043eu043cu043au0440u0430u0442u043du043eu0439 batteries. 3).
