摘要
合流暗渠一般采用渠口截污方式实施截污,此类截污将造成水体雨季溢流污染,致使河道黑臭。为实现合流暗渠清污分流,实现渠口截污闸的完全打开,首先从摸查、物探、设计和施工角度分析了暗渠清污分流改造遇到的难点,研究了排水管渠摸查要求、路线和方法,随后根据暗渠两侧的施工条件,提出了不同施工条件下的暗渠截污的方法,最后给出了暗渠清污分流效果检验要求。
Confluence culverts generally adopt the sewage interception method at the exit,Such interception will cause overflow pollution during the rainy season,causing the river to be black and smelly.In order to realize rainwater and sewage separation of confluent culverts and the complete opening of the sewer interception sluice,We first analyzed the difficulties encountered in culvert cleaning and diversion reconstruction from inspection,geophysical exploration,design and construction,and studied the requirements,routes and methods of drainage pipe inspections.Then,according to the construction conditions of the culvert.Finally,we given the inspection requirements of confluence culvert of rainwater and sewage separation.
