The award is new!The Kunming Metro Line 4 project participated in the design of China Railway Second Bureau won two honors

It is reported that Kunming Metro Line 4 is the longest line of Kunming Metro, with a total of 29 stations. China Railway Chengdu Design Institute undertakes the design work of Jingui Street Station, Niutou Mountain Station and Lianjie Street Station. Jingui Street Station and Niutou Mountain Station are two underground island stations. Lianjie Street Station is the underground three -story island stations. As a heavy difficulty project across the board, Lian Street is facing problems such as complex geographical environment, intensive pipelines, high risks of relocation, and difficulty in civil defense setting, which brings great challenges to engineering design.

Facing the challenge, the China Railway Chengdu Design Institute adheres to the concept of providing customers with high -quality design services. On the one hand, the design team is built to choose a project team with rich work experience and outstanding business capabilities. Work, strengthen the communication and cooperation of various majors, break through the professional technical barriers of various professionalism, and ensure that the team's maximum joint efforts are used in the process of project tackling. On the other hand, strengthen the design advantages of technology research. The design team combines the project's heavy difficulties, adopts the breakthrough design of advanced dark excavation methods, and creates the problem of defense settings collected by different stations at the limited building space station. The problem of relocation and reform under the scale of the station is limited.

Aiming at the southeast of the intersection where Lianjie Station is located as a planned residential area, in order to reduce the impact of long -term design on the planned residential area, the design team uses a seamless rail and special shock absorption to reduce the noise of the train. Design mufflers to reduce noise generated by high -power fans and greatly enhance the comfort of building use around the subway. In addition, in the vertical surface design of the station and line, the design team cleverly adopts the "energy -saving slope" design, that is, the station is at the highest point of the line section of the line, and both ends of the stations are downhill. The design principles, use the subway to slow downhill, speed up the stations downhill, and speed up, and effectively achieve the purpose of creating energy and energy and saving.
