Sewage pipeline transformation method and equipment
The invention provides a sewage pipeline transformation method and equipment. According to the sewage pipeline transformation method, a vertical shaft is dug at a to-be-transformed sewage pipeline to transform the to-be-transformed sewage pipeline; then, a connecting channel of the current construction section and the adjacent construction section of the sewage pipe to be transformed is blocked, water guiding is conducted on the current construction section, and segmented water guiding is achieved; the sewage pipe in the current construction section is subjected to desilting operation, so that the cleanness of the construction environment is guaranteed; and finally, a new pipeline is installed in the sewage pipe in the current construction section, a closed water test is conducted on the new pipeline, and when the result of the closed water test is qualified, construction of the current construction section is ended, and construction of the next construction section is started. According to the method, segmented sewage transformation is realized through earlier stage treatment of the sewage pipeline and installation and test of a new pipeline, and a transformation process is set and an operation environment is improved, so that the difficulty of sewage transformation is reduced.
本申请提供了一种污水管线改造方法及设备，通过在待改造的污水管线处挖设竖井以对待改造的污水管进行改造；然后封堵待改造的污水管的当前施工段与相邻施工段的连接通道，并对当前施工段进行导水，以实现分段导水；并对当前施工段内的污水管进行清淤操作，以保证施工环境的清洁；最后在当前施工段内的污水管内安装新管道，并对新管道进行闭水测试，当闭水测试的结果合格后，结束当前施工段的施工，开始下一施工段的施工；通过污水管线的前期处理和新管道的安装、测试，以实现分段式污水改造，且设定改造的流程和改善作业环境，从而减低污水改造的难度。
