Problems solved by technology

[0002] Sewage pipes are an indispensable part of high-rise building construction. Its function is to discharge waste water and excrement in high-rise buildings to the outside. In daily life, the phenomenon of blockage of sewage pipes occurs from time to time, which brings great harm to people's daily life. many inconveniences
[0003] When there are many serious blockages in the sewage pipeline, the staff need to dredge the sewage pipeline through dredging equipment. When dredging, it starts from the beginning of the sewage pipeline. When it flows downward, when it flows to the next blockage, it will mix with the blockage here, causing a secondary blockage. The secondary blockage is more serious than the primary blockage and difficult to clear, which brings great inconvenience to the residents. , has seriously affected the quality of life of the residents. At the same time, the above dredging methods can only be used by the residents of the entire building after the sewage pipes are completely dredged, and the dredging time is relatively long.

Embodiment 1

[0039] Embodiment 1: a kind of multi-stage dredging method of sewage pipeline, as figure 1 As shown, a section of sewage pipeline 1 is taken as an example for illustration. The sewage pipeline 1 is equidistantly provided with a number of dredging openings 2 along its length direction. The dredging method includes the following dredging steps:

[0040] Step a: Dredge the dredging port 2 close to its terminal on the sewage pipe 1;

[0041] Step b: After dredging, suck away the blockage in the pipeline between the dredging port 2 and the terminal of the sewage pipeline 1;

[0042] Step c: Repeat step a and step b to dredge the dredging openings 2 of the sewage pipe 1 along the direction from the terminal to the beginning in sequence until the dredging operation is completed.

[0043] By performing segmental dredging from the end to the beginning of the sewage pipeline 1 , secondary blockage of the sewage pipeline 1 can be effectively avoided, thereby shortening the processing ti...

Embodiment 2

[0054] Embodiment 2: a kind of multi-stage dredging method of sewage pipeline, such as Figure 4 Shown, it is applied to the dredging of the sewage pipeline 1 of high-rise building, and sewage pipeline 1 comprises the main pipeline 11 that vertically arranges along high-rise building and the branch pipeline 12 that is arranged on each floor, and one end of branch pipeline 12 communicates with main pipeline 11, The other end is communicated with householder 7, and branch pipe 12 is equidistantly provided with some dredging mouths-21 along its length direction, and each dredging mouth-21 place is all provided with dredging device 3, is used to dredge branch pipe 12.

[0055] The main pipeline 11 is located on the pipeline between the adjacent branch pipelines 12 and is equidistantly provided with some dredging openings 222, and the dredging openings 222 are arranged along the length direction of the main pipeline 11, and each dredging opening 22 is provided with a dredging device...

Embodiment 3

[0067] Embodiment 3: a kind of multi-stage dredging method of sewage pipeline, such as Figure 4 As shown, the difference from Example 2 lies in step s6-step s9. In order to distinguish it from the mark in Example 2, step p6-step p9 is used in this Example 3;

[0068] Step p6: Repeat step s4 and step s5 in Example 2, and dredge the dredging port 2 22 close to the terminal of the sewage pipeline 1 upwards along the main pipeline 11. , give priority to dredging the branch pipeline 12;

[0069] Step p7: When dredging the branch pipeline 12, first open the dredging opening 21 of the branch pipeline 12 near the end of the main pipeline 11, and use the dredging device 3 installed there to clean the branch pipeline between the dredging opening 21 and the main pipeline 11. 12 to dredge;

[0070] Step p8: After dredging, suck away the blockage in the pipeline between the dredging port 21 and the terminal of the sewage pipeline 1;

[0071] Step p9: Repeat step p7 and step p8, and dre...

Abstract

The invention discloses a multi-section dredging method for a sewage drainage pipeline. The multi-section dredging method comprises the sewage drainage pipeline and a plurality of dredging openings arranged on the sewage drainage pipeline. The multi-section dredging method comprises the following dredging steps: step a, dredging the dredging opening close to the final end of the sewage drainage pipeline; step b, after dredging, sucking blocking articles in the pipeline arranged between the dredging opening and the final end of the sewage drainage pipeline away; step c, repeating the step a andthe step b and sequentially dredging the dredging openings in the direction from the final end to the beginning end of the sewage drainage pipeline until dredging operation is finished. The multi-section dredging method disclosed by the invention has the advantages of effectively dredging the sewage drainage pipeline which is seriously blocked at multiple positions in a high-rise building and preventing secondary blocking.
