- Abstract:
- The rural sewage network project of Yixing City involves 18 towns and streets, including 503 villages and 108 roads. Based on the topographic features of high south and low north and dense river network in this area, the “one village, one policy” scheme was designed according to the principle of “centralization if possible, decentralization if desirable”, so as to solve the problems such as scattered village planning and layout, lack of drainage facilities and large variation coefficient of sewage. The designers stationed on-site to survey and determine the pipeline route, and a variety of treatment models such as sewage collecting into the municipal network, relatively centralized treatment and decentralized treatment were adopted to reduce the sewage volume directly discharging into the natural receiving waters and environmental risks. A new erection method of pipe along the river adapted to the site conditions was invented to solve the problem of inconvenient construction. In addition, a new energy dissipation plate was innovatively applied to optimize the traditional energy dissipation well and effectively solve the downstream pipeline overflow problem.
