The utility model discloses an overflow type anti-backflow and diversion three-way well suitable for urban confluent pipe culvert, including a well body with a well cover, the bottom of the well body is provided with a confluent main culvert, and the confluent main culvert is provided with a push-pull type overhaul manhole positioned directly below the well cover, and the top of the confluent main culvert. The overflow pipe leading to the eight-character discharge outlet of the river course is arranged outward, and the part of the overflow pipe and the main culvert of the confluence system in the well body forms a three-way downstream structure; the end of the overflow pipe is provided with a racket door of the outer cover decontamination basket, which is sliding connected with the vertical guide rail arranged on the side wall of the eight-character discharge outlet of the river course. The trash basket is connected to the fixed platform of the waterfront platform through a connecting rod arranged at the top. The utility model has the advantages of simple structure, enlarging the interception multiple of the combined drainage pipe culvert, smoothly discharging the overflow water and efficiently collecting floating garbage, and effectively solving the problems caused by the water leakage of the main culvert inspection well.

,尤其是涉及一种适于城市合流管涵的溢流式防倒灌导流三通井。
技术介绍
随着现代化城市进程的加快,城市合流制排水管涵的污染以及雨季合流水截流溢流问题变得日益严重。合流制管道的溢流污染已成为部分城市改善水体水质的主要制约因素之一。但是,从国内外城市排水系统长期的实践经验和现实情况看,部分合流制系统的存在是不可避免的。因此,城市水环境质量要想得到根本改善,就必须加强对合流制管道溢流污水的管理和控制。但是,普通的合流制截流井工艺结构不够完善,溢流水通过截流井时不够顺畅,影响了排水系统的过流能力,降低了截流式合流制排水系统的截流倍数。此外,由于合流式排水管涵较普通其他排水管涵内漂浮物较多,而合流制截流井的溢流管道一般较小,容易被堵塞,致使大部分溢流形同虚设。反之,若为了顺畅排出合流制管涵内的漂浮垃圾而增大溢流管直径,合流制管涵的截流倍数将下降,溢流水对河流的污染将加重。根据调查统计情况,目前合流制排水管涵截流溢流井的溢流管道末端或者没有垃圾拦截措施,或者设置拦污栅作为垃圾拦截措施,前者会对河流造成严重污染, ...
