It is adjacent to Hong Kong and is the main venue for the 26th Summer Universiade in 2011. It is also the key urban landscape and public event space of Shenzhen in the future.

      The entire project covers an area of ​​about 30.74 hectares with a total construction area of ​​256,000 square meters. Upon completion, it will become another landmark building in Shenzhen. The project includes stadiums, gymnasiums, swimming pools, athlete reception service centers, sports theme parks and commercial operation facilities. Among them, the main stadium planning to build 20,000 fixed seats will undertake the competition and training functions of the Universiade football preliminaries; the main stadium that can accommodate 13,000 spectators will become the main venue for the Universiade table tennis game; the swimming pool will also take the swimming Training function of the game.

      Shenzhen Bay Sports Center is also a major innovation in sports architecture. The unique design called “Chunxi” integrates “a two-storey building” with commercial facilities in a building space through a large roof made of white giant grid structure. The integration of the project, in addition to the integrated, composite, and activated design of the project is very beneficial to the comprehensive utilization after the pre-match.

      After the Universiade, the center, open to the general public, has become the core venue for national fitness and an important venue for large-scale sports events at home and abroad. The Shenzhen Bay Sports Center project is undergoing a soft foundation treatment phase. The steel structure hoisting is scheduled to be completed on April 30, 2010. The overall roof closure will be completed on August 30, 2010, and the completion acceptance of the project on December 31, 2010 will be carried out in March 2011. Acceptance of sports facilities.

Project requirements

 

The public broadcasting system of the venue is designed and installed for the daily background music playback, information dissemination, broadcast notification, person finding, background music and other functions of the stadium. In an emergency, the public broadcasting can cooperate with the fire-fighting broadcasting system to quickly report the emergency evacuation voice to the scene of the accident, prompting the personnel in the relevant area to quickly flee the scene; the design of the public broadcasting system mainly considers the public walkway covering the stadium.

 

        The sound reinforcement design of the venue press room mainly meets the functions of audio sound reinforcement, digital conference, signal switching, signal display and central control.
