- Abstract:
- The design method for systematic reconstruction of the drainage network in Luojiahu pumping station drainage system around Hexi University Town in Changsha City was introduced. In the design, a hydraulic model of the drainage network was constructed based on HY-SWMM platform. The project ensured that the drainage network met the functional requirements of drainage and water-logging prevention and the diversion of stormwater and sewage through hydraulic simulation of the pipe network, optimization of the drainage pipe design, verification of the water depth of the water body in water-logging areas, cooperation with the diversion of stormwater and sewage in the system. In addition, structural and functional defects of the current pipe network were explored and evaluated in detail, and a reasonable pipe network structural repair scheme was designed through CCTV, QV and other pipe network detection techniques. The stormwater and sewage diversion of the drainage network, partition drainage of stormwater in high and low elevation districts, water-logging prevention and control, pipe network repair and other works were systematically completed through the drainage function and structural safety construction of the pipeline. At present, the main pipeline of this project has been put into operation and shown a good performance.
