Background

When laying a drainage pipe network, two or more than two various pipelines are crossed at the same depth or a place with small depth difference (less than or equal to 100mm), but do not need to be connected, so that the pipelines must be mutually separated. The general avoidance mode is that the elevation of a pressure pipeline is reduced by using a pipe fitting to bypass a self-flowing pipeline or other pipelines, and according to the standard requirement, the pipe diameter of the pipeline is more than or equal to 300mm, when the two pipelines are crossed, the distance between the two pipelines must be more than 500mm, so that the actual implementation is very difficult. The descending pipe may descend deep, which may affect the construction cost of the whole water supply and drainage pipe network. In particular, if the two intersecting pipes are gravity flow pipes without pressure, water cannot flow into a drainage point at a predetermined elevation normally if the elevation is lowered. Therefore, the problem of cross collision of pipelines needs to be solved, the elevation of the gravity flow pipeline is reduced or not reduced as much as possible, and sewage can be normally discharged to a drainage point with a preset elevation.
