Sewage pipeline transformation construction method
The invention belongs to the technical field of municipal engineering construction, and discloses a sewage pipeline transformation construction method. The sewage pipeline transformation construction method comprises the following steps: determining a transformation position; laying a first expanded sewage pipeline and/or a second expanded sewage pipeline; laying a temporary blow-off pipeline; closing part of the to-be-transformed sewage pipeline, connecting the to-be-transformed sewage pipeline with the temporary blow-off pipeline, and recovering water supply; repeating the previous step until all the to-be-transformed sewage pipelines are connected with the temporary blow-off pipeline and water supply is recovered; building a piping shaft; closing part of the to-be-transformed sewage pipeline, separating the to-be-transformed sewage pipeline from the temporary blow-off pipeline, connecting the to-be-transformed sewage pipeline into the pipeline shaft, and recovering water supply; and the previous step is repeated until all the to-be-transformed sewage pipelines recover water supply, and the second expansion sewage pipeline can be connected into the pipeline shaft. By means of the method, the pollution discharge direction can be changed, the pollution discharge capacity is improved, and it can be always guaranteed that part of the to-be-transformed sewage pipelines are in the pollution discharge state.
本发明属于市政工程施工技术领域，公开了一种污水管道改造施工方法。该污水管道改造施工方法包括以下步骤：确定改造位置；铺设第一扩充污水管道和/或第二扩充污水管道；铺设临时排污管道；关停部分待改造污水管道并将与临时排污管道连接并恢复通水；重复上一步骤，直至所有待改造污水管道均与临时排污管道连接并恢复通水；建设管道井；关停部分待改造污水管道并将其与临时排污管道分离，将待改造污水管道接入管道井并恢复通水；重复上一步骤，直至所有待改造污水管道均恢复通水，还可将第二扩充污水管道接入管道井。使用该方法不仅能够改变排污方向、增加排污能力，还能够始终保证部分待改造污水管道处于排污状态。
