Project Name: Qian Jiang New International Conference Center

Project Overview: The Qianjiang New City International Conference Center is located on the banks of the Qiantang River in Hangzhou, with a building height of 85 meters. The main building consists of a 12 meter elliptical podium and an upper sphere with a diameter of 85 meters. The waterproof construction area of the building is 27000 square meters. According to the structural characteristics of the Hangzhou International Convention Center, the waterproof design of this project follows the principle of "combining prevention, drainage, interception, and blocking, balancing rigidity and flexibility, adapting to local conditions, and comprehensive management". The underground part is designed with waterproof level II protection. The preliminary design of the basement floor is based on structural self waterproofing, with an additional 5mm thick polymer cement mortar. 2mm thick polyester tire self-adhesive polymer modified asphalt waterproofing membrane is used as the waterproof layer for the basement exterior wall and roof, and the node parts are reinforced with protective measures.
