Description

Monitoring system capable of monitoring pipeline deformation and inspection well thereof

Technical Field

The utility model relates to the technical field of pipeline deformation monitoring, in particular to a monitoring system capable of monitoring pipeline deformation and an inspection well thereof.

Background

In order to discharge sewage, rainwater and the like, a plurality of drain pipes are installed in the current cities, and form a drain pipe network. At present, the drainage pipe in a city is usually buried under the ground, and when the drainage pipe is installed, a groove needs to be dug on the ground, then the drainage pipe is placed in the groove, and soil is used for backfilling. In order to improve the land utilization rate, facilities such as highways, buildings, flower beds for greening and the like can be built above the drainage pipe, and taking the highways as an example, when a car runs above the drainage pipe, the car can apply larger pressure to the highways, and the backfilled soil is difficult to achieve the same compactness as the un-excavated soil even if the backfilled soil is tamped; and the compactness of the soil backfilled everywhere in the groove is difficult to keep consistent during tamping, so that the backfilled soil is easy to settle under the larger pressure of an automobile, and the backfilled soil is irregular to settle because the quantity of the soil on the two sides of the drainage pipe is different from that of the soil right above the drainage pipe and the compactness of the backfilled soil cannot be completely the same. Because the existing drain pipe is usually made of plastic materials, the top of the drain pipe is bent or sunken to deform under the action of irregular settlement, and the section of the drain pipe cannot keep a round shape after the drain pipe deforms, so that the drainage quantity of the drain pipe per unit time is reduced, and the drain pipe is easy to block when sewage contains impurities; the serious deformation can even lead to the cracking of the drain pipe, thereby causing the sewage leakage.

However, in actual practice, since the drain pipe is buried underground, it is impossible to determine whether the drain pipe is deformed by observing the appearance of the drain pipe, and the number of the drain pipes increases with the increase of the urban area, and it is impossible to manually check the drain pipes one by one at regular intervals. The drainage net can be restored to drainage by replacing the drainage pipe only when the drainage pipe is blocked or even leaked. However, when the drainage pipe is replaced, the road surface above the drainage pipe needs to be excavated to expose the drainage pipe, and then the drainage pipe can be replaced, so that the traffic of the road above the drainage pipe is hindered undoubtedly, and the replacement cost is increased when the road surface is restored; the caliber and the weight of the drain pipe are large, the transportation and the replacement can be completed by more people, the labor intensity and the labor cost of the replacement are high, and therefore a monitoring system capable of monitoring the deformation of the pipeline is needed.
