Description

Sewage pipes for hydraulic engineering

Technical Field

The utility model relates to a hydraulic engineering field specifically is a sewage pipes for hydraulic engineering.

Background

The sewage in the sewage pipeline contains a certain amount of organic matters and inorganic matters, wherein the sewage with small relative density floats on the water surface and drifts along with the sewage; the heavier water flow is distributed on the section of the water flow and flows in a suspension state; the heaviest of these move along the bottom of the tube or pool on the walls of the tube, in a slightly different manner than the flow of fresh water. However, in general, the water content of the sewage is generally above 99%, and the proportion of the suspended substances contained in the sewage is small, so that the flow of the sewage is assumed to generally follow the flowing rule of the water flow, and the water flow in the pipeline is assumed to be uniform. However, the measured results of the flow of water in the sewer pipe indicate that the flow rate in the pipe is variable. This is mainly because the pipe is small, and when the water current flows through a bend, a cross, a slope, a diameter change, a water drop and the like, the water current state changes, the flow speed also changes continuously, and possibly the flow rate also changes, so under the above conditions, the water current in the sewage pipe does not flow uniformly. However, in addition to the above, in the linear pipe section, when the flow rate is not greatly changed and there is no sediment, the hydraulic elements (speed, pressure, density, etc.) of the sewage in the pipe do not change with time, and can be regarded as a constant flow, and the section, shape and size of the pipe are not changed, and the flow lines are parallel straight lines, and the flowing state of the flow lines can be regarded as a uniform flow. If care is taken to improve the hydraulic conditions of the pipeline during design and construction, the water flow in the pipe can be made as close to uniform flow as possible.

If not in time handle sedimentary mud in the pipeline, cause the problem that the pipeline blockked up or the flow descends easily, influence sewage pipes's use, this application provides a sewage pipes that can handle pipeline sedimentary mud.
