基于重难点控制的合流渠箱施工关键技术分析

Analysis of Key Technologies for Combined Channel Box ConstructionBased on Key and Difficult Points Control

老城区的合流渠箱在城市水利工程发展过程中已无法满足排水的需求,尤其是在雨季时,容易造成水体溢流污染道路等情况。为了更好地解决老城区排水问题以及渠箱的污染问题,有必要对合流渠箱建设过程中施工技术的重难点进行分析。本文以广州市某段道路的合流渠箱的清污分流改造为例,首先阐述该水利市政工程项目在改造建设中的重难点,随后针对其项目特点,对排水体制进行梳理,给出相应的整治和改造方案,最后对其重难点进行逐一分析,根据重难点特点结合管理流程提出相应的对策与建议。在溢流污染的问题上,采用清污分流的方法进行改造。拟对相关合流渠箱的清污分流改造工程提供参考。

The confluence channel boxes in the old urban area are no longer able to meet the drainage needs during the development of urban water conservancy projects,especially during the rainy season,which can easily cause water overflow and road pollution.In order to better solve the drainage problems and pollution problems of the old urban area,it is necessary to analyze the key and difficult points of construction technology in the construction process of the combined channel box.This article takes the cleaning and sewage diversion renovation of a certain section of road in Guangzhou as an example.Firstly,it elaborates on the key and difficult points in the renovation construction of the water conservancy municipal engineering project.Then,based on the characteristics of the project,it sorts out the drainage system and provides corresponding renovation and renovation plans.Finally,it analyzes the key and difficult points one by one,and proposes corresponding countermeasures and suggestions based on the characteristics of the key and difficult points combined with the management process.On the issue of overflow pollution,the method of separating clean and dirty water is adopted for renovation,and it is planned to provide reference for the renovation project of separating clean and dirty water in relevant confluence channel boxes.
