村镇建筑排水接户管设计研究

Design and Research of Drainage and Inter-building Pipe in Rural Buildings

接户管作为乡镇生活污水治理工程的重要组成部分,其建设是提高污水收集率和污水厂进水浓度的重要举措。该文以湖北省某市13个乡镇接户管为例,分析接户管设计原则,根据现场不同的实际情况分别采取不同的设计方案,并从工程量及造价方面与已建主支管网进行对比。结果表明:主支管长度与接户管长度基本成正比,接户管长度平均为主支管网长度的1.11倍,接户管单位投资低于主支管网。

Inter-building pipe is an important part of the township sewage treatment project,and its construction is an important measure to increase sewerage collection rates and the in-fluent concentration of sewage treatment plants.Based on the inter-building pipes in 13 towns of a city in Hubei province,the design principles of the inter-building pipe were analyzed.Different schemes have been adopted based on different field conditions.The engineering quantity and investment amount were contrasted with the built main and branch pipelines.The results showed that the length of the main and branch pipelines is basically proportional to the inter-building pipe,the length of inter-building pipe is 1.11 times of the main and branch pipe network,and the unit investment of inter-building pipe is lower than the main and branch pipe network.
