Construction System and Method of Shallow-Buried Deep-Tunnel under Existing Railway Line
The present invention discloses a construction system and method of a shallow buried deep-tunnel under an existing railway line and proposes reasonable pre support and excavation construction technology to ensure the safety of construction of the railway line under a tunnel. The present invention mainly includes the following aspects: (1) optimizing a main construction method of tunnel excavation; (2) selecting an appropriate support structure and auxiliary construction measures for the tunnel excavation; (3) reinforcing a subgrade slope of the railway line under the tunnel; and (4) strengthening and stabilizing a track of the railway line under the tunnel. The construction system and method of the shallow-buried deep-tunnel under the existing railway line proposed by the present invention fully considers interaction between a newly built tunnel and the existing railway line, and a coupling effect of surrounding rock and different support methods, optimizes a support and excavation solution, and explores an efficient and systematic construction safety management mode of an existing railway line project under a shallow-buried and underground excavation tunnel. FIGURES OF THE SPECIFICATION r Optimize a main construction method of tunnel excavation; ?Select an appropriate support structure and auxiliary construction excavation; Reinforce a subgrade under the tunnel; under the tunnel.
