- Abstract:
- A height conflict occurred due to the intersection of a newly constructed d1 000 mm sewage pipeline with the existing DN2 800 South-to-North Water Diversion Project mains in Gaocun Road, Xinxiang City. Following the principle of small diameter to avoid existing large diameter pipelines, through hydraulic calculation, the sewage pipe siphon technology was ultimately recommended for use in terms of engineering construction, operation and maintenance. The siphon system consisted of siphon pipes, inlet water seal wells, outlet water seal wells, vacuum pipes, vacuum pumps, and other components. By incorporating a sedimentation tank in the inlet water seal well, selecting a large design flow rate, implementing regular flushing and vacuum pumping procedures, the issues related to vacuum pipe failure, blockage, leakage and pollution in the sewage pipeline were effectively resolved, and this ensured the normal operation of the system.
