Embodiment 1
[0030] Using the above scheme, it is composed of the blocking disk 1, the tensioning winch 2, the tensioning steel wire 3 and the push rod 4, the tensioning winch 2 is connected with the blocking disk 1 through the tensioning steel wire 3, and the umbrella fan of the sealing disk 1 is contracted 13. Push the pull rod 4 to send the occlusion disk 1 into the lumen, after the occlusion disk 1 is automatically opened, the tension steel wire 3 is tightened to tightly combine the occlusion disk 1 with the lumen wall to form a retaining mold.
[0031] The blocking disc 1 is a paper umbrella-shaped structure, which is composed of an umbrella top 11, a support seat 12, an umbrella fan 13, a core disc 14, and a fixed suspension ring 15 from bottom to top.
[0032] Umbrella top 11 is a papery small cylinder, which plays a protective role;
[0033] The supporting seat 12 is a paper disc, which supports the umbrella fan 13;
[0034] Umbrella fan 13 is composed of 16 paper lupines, and fol...

The invention provides an underground drainage pipeline detection hole repairing device. The underground drainage pipeline detection hole repairing device comprises a tensioning winch, the tensioningwinch is located at the upper end of a detection drill hole, a tensioning steel wire is wound on the tensioning winch, the tensioning steel wire penetrates through the detection drill hole, a blockingdisc capable of contracting in one direction is fixed to the lower end of the tensioning steel wire, and the blocking disc completely covers an end opening of the detection drill hole in an end faceprojection of the detection drill hole after stretching. The invention further provides an underground drainage pipeline detection hole repairing method. Based on the fact that the umbrella-shaped blocking disc can be manually contracted and fed into a detection hole, the umbrella-shaped blocking disc is automatically opened after entering a pipe cavity, a tight blocking die is formed at the detection hole and the pipe wall under the action of the tensioning winch and the tensioning steel wire, and hole sealing is guaranteed; the repairing method has the characteristics of good blocking quality, economy, environmental protection, convenience and rapidness, the blocking disc can be automatically degraded in the later period, and the blocking quality hidden danger is avoided; and the degradable paper material is adopted, so that environmental protection, high quality, high efficiency and remarkable social and economic benefits can be realized.
Description
technical field [0001] The invention relates to a device and method for repairing detection holes of underground drainage pipes. Background technique [0002] The main function of urban underground drainage pipes is to collect and discharge ground rainwater and domestic sewage. It is generally completed during the construction, expansion or reconstruction of cities, communities, parks or roads. It is generally buried at a depth of 1m to 2m underground, and is affected by natural or human influence in the later period. , The pipeline will be damaged, blocked, collapsed, and deformed. Therefore, it is generally stipulated that the pipeline should be inspected and repaired every few years. Due to the long distance between some pipeline testing wells, or the abnormal structure of the pipeline between two testing wells, it is necessary to drill a detection hole on the ground for the pipeline, and then check the situation inside the pipeline through the detection hole, and use the...
