- Abstract:
- The key to water environment management is to achieve complete source control and pollutant interception in the basin, and the core of source control and pollutant interception is to ensure the effect of connecting the old and new pipe networks. In order to effectively improve the sewage collection rate and ensure the effect of the pipe network construction, we firstly analyzed the difficulties encountered in the connection of the old urban pipe network from the perspective of design and construction, and proposed the four-step connection strategy of troubleshooting, connecting, leakage detection and bottom pocket. Then, the functional requirements of various connection points were analyzed, and the design samples of several non-standard inspection wells were given. Finally, it was summarized that different connection methods adopted in different situations, which provided references for the renovation of the pipe network and connection methods in the old town.
