Description
Technical field
The utility model relates to pick-up unit, and particularly, the utility model relates to a kind of concrete plug bounce-back degree pick-up unit that is used for damaged condition detection usefulness in the concrete underground pipeline.Said concrete plug bounce-back degree pick-up unit can record the damaged condition pipeline in real time, and parallel summary is concluded, and whether decision needs to repair, local repair, whole repairing etc.; Understanding is to the tubing intensity that substantial connection is arranged serviceable life of pipeline; Stabilized walking, climbing, on-slip in the underground pipeline of can be narrow and small, obstacle being arranged in the space.
The said concrete plug bounce-back degree pick-up unit of the utility model also can be used for comprising municipal drainage underground pipeline, agricultural water underground pipeline, process water underground pipeline, the detection of buried concrete underground pipelines such as tap water underground pipeline.
Background technology
In the past, to the municipal drainage underground pipeline, the agricultural water underground pipeline; The process water underground pipeline, underground pipelines such as tap water underground pipeline are formulated maintenance schedule, when declaring maintenance cost; Need to understand in advance the actual conditions of pipe interior, and predict contingent problem and accident.In the past, owing to do not have effective detection means and equipment, generally relied on naked eyes, or adopted small mirror etc., and directly the situation of pipe interior was observed and conclude.Such method thinks that interference is many, and error is big.
For to the municipal drainage underground pipeline, agricultural water underground pipeline, process water underground pipeline; The damaged condition of underground pipelines such as tap water underground pipeline is generally investigated when detecting, and a kind of pipe detection that has camera function of existing employing is used automatic crawl trolley, through people's naked eyes the image of taking at pipe interior is observed; Analyze; Draw the damaged condition of pipe interior qualitatively, and on this basis underground pipeline is made reparation, perhaps the conclusion changed etc. of renovation.
But the said pipe detection that has camera function is the situation from the surface phenomena analysis conduit of pipeline with automatic crawl trolley, can't really understand the actual strength of pipeline material, can't infer the life-span that pipeline can also use.Can cause the pipeline of unnecessary reparation but to renovate replacing like this, and the problem that needs the pipeline of emergency repair in time not repaired.Can cause the waste of funds thus; Perhaps because this is repaiied and does not build into pipeline breaking and form serious road surface and cave in, to surrounding enviroment, traffic safety and people life property safety make a big impact.
In addition; As stated; Such detection method just comes the damaged condition of pipeline is inferred through the image of pipe surface; The real if desired tubing intensity of understanding pipeline that substantial connection is arranged serviceable life; Understand the concrete plug belong to alkalescence and have or not and with the sour gas of pipe interior and liquid neutralization reaction has taken place and formed weakening of intensity, if when the phenomenon of neutralization reaction has taken place under the concrete ground degree of depth that is neutralized of pipe surface reach how dark etc. again, rely on present detection method not reach these requirements.
In sum, detection is difficult to record in real time, all sidedly the damaged condition in the pipeline with walking dolly in the underground pipeline in the past, and parallel summary is concluded, and is difficult to decision and whether needs repairing, local repair, whole repairing etc.; The tubing intensity that substantial connection is arranged serviceable life of pipeline etc. is difficult to detect; In addition, exist in, the underground pipeline that obstacle is arranged narrow and small in the space stabilized walking difficulty, climbing hard, be not easy problem such as on-slip.
