Detailed Description
The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
The new and old sewage pipeline connecting structure comprises an old sewage pipe 1, a new sewage pipe 4, a three-port communicating pipe 5, a blocking pipe 6, an inspection well 8, a new pipe communicating port 12 and an old pipe communicating port 13; the junction of the new sewage pipe and the old sewage pipe is connected with a three-port communicating pipe 5, and the upper end of the three-port communicating pipe 5 is connected with an inspection well 8; the three-port communicating pipe 5 is provided with a new pipe communicating port 12 and an old pipe communicating port 13, the new pipe communicating port 12 is connected with the new sewage pipe 4, and the old pipe communicating port 13 is connected with the old sewage pipe 1; the new pipe communication port 12 or the old pipe communication port 13 is blocked by the blocking pipe 6.
The three-port communicating pipe 5 is of a T-shaped structure, two old pipe communicating ports 13 are located on the same straight line, and the new pipe communicating port 12 is perpendicular to the old pipe communicating ports 13.
The end parts of the new pipe communicating port 12, the old pipe communicating port 13, the old sewage pipe 1 and the new sewage pipe 4 are all provided with a splicing port 2, the edge of the splicing port 2 is provided with a connecting hole 9 in a circle, and the splicing port 2 is fixedly connected through a bolt 10 and a nut 11.
The old pipe communication port 13 is connected with the old sewage pipe 1, and then the new pipe communication port 12 is blocked by the blocking pipe 6, so that the engineering can be constructed without continuous flow. And after the construction of the new sewage pipe is completed, the blocking pipe 6 is removed, the new sewage pipe 4 is connected with the new pipe communicating port 12, and meanwhile, the old pipe communicating port 13 is blocked by the blocking pipe 6, so that sewage is drained to the new sewage pipe.
