Construction method for connection of new and old sewage pipes without cutting off water
The invention relates to a construction method for connection of new and old sewage pipes without cutting off water, and relates to the technical field of new and old sewage pipes. The method comprises the following steps that S1, an operation well and a reinforcement well are formed in an existing pipeline, and a newly-built pipeline is jacked into the operation well; s2, concrete grout is poured between the operation well and the reinforcement well; s3, a cutting device is hoisted into the operation well through a small crane, the cutting device and the newly-built pipeline are fixed, and then the existing pipeline is cut through the cutting device to form a connection opening; during cutting; the upstream well needs to fully pump water to lower the water level in the existing pipeline; after cutting is completed, the cutting device is hoisted to the operation well; and S4, the connection pipe is fixed to the existing pipeline through the surrounding assembly, the connection pipe communicates with the connection opening, then the newly-built pipeline is connected with the connection pipe, and therefore connection of the newly-built pipeline and the existing pipeline is achieved. The connecting device has the effect that the connecting opening formed by cutting can be accurately aligned with the newly-built pipeline.
本申请涉及一种用于新旧污水管不停水接驳的施工方法，涉及新旧污水管技术领域。其包括以下步骤：S1、在既有管道处开设操作井和加强井并将新建管道顶入至操作井内；S2、在操作井和加强井之间浇筑混凝土浆；S3、将切割装置通过小型吊机吊至操作井内，并将切割装置与新建管道固定，然后通过切割装置对既有管道进行切割而形成接驳口；切割时；上游井要全力抽水来降低既有管道内的水位；切割完毕后，再将切割装置吊处操作井；S4、将接驳管通过环绕组件固定于既有管道上且接驳管与接驳口连通，然后再将新建管道与接驳管连接，从而实现对新建管道和既有管道的接驳。本申请具有切割形成的接驳口能与新建管道精准对正的效果。
