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 deep well point inspection well for the new and old sewage pipelines comprises a plugging pipe 6, a solid base 23, a fixed base 24, split bolt holes 25, solid blocks 26, an old pipe communicating pipe 29, a new pipe communicating pipe 30, a splicing ring 31, a splicing circular groove 32 and a well chamber 33; the solid base 23, the fixed base 24 and the split bolt holes 25 are combined into an inspection well base, the solid block 26 at the bottom of the three-port communicating pipe 5 is inserted into the fixed base 24, and the solid block 26 is aligned with the split bolt holes 25 on the fixed base 24 and is connected and fixed through the screw 28; the well chamber 33 is spliced at the top of the three-port communicating pipe 5, and the splicing circular groove 32 at the bottom of the well chamber 33 is matched and connected with the splicing circular ring 31 at the top of the three-port communicating pipe 5; the three-port communicating pipe 5 is provided with two old pipe communicating pipes 29 and a new pipe communicating pipe 30, and the new pipe communicating pipe 30 or the old pipe communicating pipe 29 is blocked by the blocking pipe 6.

The splicing openings 2 of the new pipe communicating pipe 30 and the old pipe communicating pipe 29 are provided with bolt holes 27 matched with the blocking pipes 6.

The upper end and the lower end of each well chamber 33 are respectively provided with a splicing circular ring 31 and a splicing circular groove 32, and the adjacent well chambers 33 are spliced together through the splicing circular rings 31 and the splicing circular grooves 32.

In the new pipe construction process, the new pipe communicating pipe 30 can be blocked by the blocking pipe 6, so that sewage flows out of the old pipe communicating pipe 29, the purpose of non-stop construction is achieved, after the new pipe construction is completed, the blocking pipe 6 on the new pipe communicating pipe 30 is removed, then the new pipe is connected, and the old pipe communicating pipe 29 on one side is blocked by the removed blocking pipe 6, so that the new and old sewage pipes are communicated.

The construction method of the new and old sewage pipeline deep well point inspection well comprises the following steps:

(1) and (6) excavating a foundation pit. The excavator is used for excavating the foundation pit, and the waste water pipe is not damaged when the foundation pit around the old waste water pipe is excavated.
