Description

Technical Field

[0001] The utility model belongs to the technical field of water-tightness detection, and particularly relates to a quick-type water-tightness test detection device for urban reconstruction. Background Art

[0002] With the rapid development of the city, the underground pipe network ancillary systems built in the early years have aged, the urbanization rate has increased, the old urban areas have improved quality and efficiency, and there are more and more urban renovation projects, especially pipe network renovation. The infrastructure development in the early years was immature, and the underground pipe network system and the municipal management network system did not develop synchronously. In addition, due to the accumulated natural wear and tear and various loads, many drainage pipes have suffered serious wear, dislocation, collapse, and fracture; at the same time, the flow demand of many old street drainage pipes cannot meet the current needs, which has also caused great difficulties for the drainage of existing road surfaces. At the same time, water damage such as water accumulation or poor drainage has shortened the service life of the newly renovated roadways.

[0003] At present, many projects for the renovation of pipeline networks in old urban areas and streets only involve the reconstruction or addition of interval pipelines, without adding or repairing the original inspection wells, resulting in the inability to test the tightness of the pipelines after completion. The specification requires that the closed water test must be carried out with a well test, but due to the particularity of the renovation project, most pipelines are not tested again after construction is completed.

[0004] Currently, there is no special test device for pipeline water closure detection. All water is filled in on-site inspection wells or newly built inspection wells. After reaching the design head, it is left to stand for 24 hours, and then water is added to the design head. Then, the water level drop is observed every half an hour and recorded three times. After calculation, it is compared with the allowable value of standard seepage flow for each pipe diameter to check whether the water closure result is qualified.

[0005] Except for new construction or reconstruction of pipelines with inspection wells, other simple pipeline replacements and pipeline reconstructions have not been tested for water closure, and the quality and tightness after construction are difficult to guarantee. The on-site use of inspection well water filling construction is less safe and there are drowning accidents. Manual reading of water level probes has low efficiency and accuracy. Affected by weather and temperature, water level changes are also different, and the final result has large errors. For pipeline projects with large engineering volumes, a large amount of manpower and water resources are required, which is time-consuming and labor-intensive, and may even affect the operation of the next process.
