管道工程施工中,有时会遇到埋入地下的管道漏水。当地面为素土时,漏水点会返潮,比较容易找出渗漏点。但是,如果地面是混凝土或水磨石等不透水地面时,漏水点就很难找到。如果全部开挖寻找漏水点,工作量很大,浪费严重。我们在某工程中,采用了“对分法”寻找漏水点。这个工程的管线长100米, In the construction of pipelines, leakage of buried pipelines is sometimes encountered. When the ground is prime soil, the leaking point will return to the tide, and it is easier to find the leakage point. However, if the floor is impervious to concrete or terrazzo, the leaking point is difficult to find. If all the excavations are looking for leaks, the workload is heavy and the waste is serious. We used the “division method” to find leaks in a project. The pipeline length of this project is 100 meters.
