Abstract

The invention provides a rail transit hole transition section protection method, and also provides a rail transit hole transition section combined protection type sound barrier. The structure of the rail transit hole transition section combined protection type sound barrier comprises a frame and auxiliary accessories, wherein the frame comprises a door-shaped frame and purlines, the purlines are fixedly connected with the door-shaped frame, so that the frame with certain bearing capacity is formed, and the auxiliary accessories comprise a protective net and a sound barrier. According to the protection method, a closed structure design is adopted, the sound barrier with sound absorption and sound insulation functions is arranged on the frame, and the noise reduction requirement of a train entering and exiting the hole section is met; the protective net is arranged at the hollow part of the top of the frame to form a closed structure, so that the safety protection of the hole section isenhanced; and due to the fact that the protective net adopts a net structure, the protective net is relatively high in permeability, so that the closed type protective sound barrier is formed withoutadditionally arranging a ventilation and smoke discharging device and a lighting device, and the protection requirement of a train entrance and exit hole section and the vehicle running requirement can be met.

Description

technical field [0001] The invention relates to the technical field of rail transit protection equipment, and more particularly, to a protection method for a transition section of a rail transit tunnel entrance and a rail transit tunnel entrance transition section combined with a protective sound screen. Background technique [0002] In recent years, with the rapid development of urban rail transit, for line laying methods, underground lines are generally used in urban central areas, and elevated lines or ground lines are mostly used in suburban areas or in and out of vehicle sections. The transition between the underground line and the ground line is connected by the transition section of the opening. [0003] The transition section of the entrance is formed by a concrete baffle to form a U-shaped groove open structure, and the concrete baffle forming the U-shaped groove is about 1 meter above the ground. [0004] When the tunnel entrance transition section is unavoidably ...
