The Zhongshan northern group waste incineration power plant and leachate treatment plant project which is designed by CCEPC started the foundation pile work on Apr. 20, 2006 and lasted two and half years to complete the main structure. The structure of this project combined all the wisdom of staffs in construction department and created many “first” in CCEPC, such as the first time to self-design feeding bridge (according to the municipal bridge design), the first time to use tube truss (roof trusses span up to 40m), the first time to self-design multi-chimney (inside is twin-tube vertical flue, outside is reinforced concrete structure, ladders and flue gas analysis room are also inside). The construction department raises their own design level through this project and laid a good foundation for more complex structure project in the future.
