Description

Technical Field

[0001] The utility model relates to the field of sewage drainage inspection, and in particular to an assembled reinforced concrete sewage drainage inspection well capable of real-time monitoring. Background Art

[0002] Due to global climate and environmental changes, extreme rainfall occurs more and more frequently. As my country's urbanization level has significantly increased, cities, as political, economic, social, cultural and transportation centers, have industrial clusters and dense populations. The surface water storage capacity has declined, which has seriously weakened the city's ability to resist rainstorms and floods. Once a flood disaster occurs, it will cause unpredictable losses. However, due to the overall planning and construction, the structural layout and municipal infrastructure of the city are difficult to re-optimize. Therefore, in extreme weather, improving the early warning capability of flood disasters is of great significance to urban disaster prevention, mitigation and avoidance.

[0003] Inspection wells are an important part of urban infrastructure construction. They are usually used for traditional work such as pipeline maintenance and sludge removal, but fail to play the role of early warning of flood disasters. The establishment of inspection wells requires a lot of manpower and material resources, but their functions have not been fully developed and utilized. Therefore, in the face of an environment prone to flood disasters, it is urgent to establish an assembled reinforced concrete sewage and drainage inspection well that can be monitored in real time. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to overcome the above-mentioned shortcomings and provide an assembled reinforced concrete sewage and drainage inspection well that can be monitored in real time. The sewage in the underground drainage pipe flows into the inspection well through the connecting pipe. The sewage level in the inspection well continues to rise with the increase of the sewage water pressure in the underground drainage pipe. When the sewage level in the inspection well rises to the water level warning line, the water-sensitive sensor issues a warning, thereby achieving the purpose of real-time monitoring of whether flood disasters may occur.

[0005] In order to achieve the above object, the utility model comprises the following steps:

[0006] A prefabricated reinforced concrete sewage and drainage inspection well capable of real-time monitoring, characterized in that it comprises an underground drainage pipe, a connecting pipe, a valve, a steel outer cylinder, a prefabricated reinforced concrete inner cylinder, a water-sensitive sensor, and a well cover; the connecting pipe is connected below one-half the height of the underground drainage pipe; the underground drainage pipe and the connecting pipe are connected by a flange; the connecting pipe and the steel outer cylinder are connected by a flange; the bottom of the steel outer cylinder is closed; the bottom of the prefabricated reinforced concrete inner cylinder and the bottom surface of the steel outer cylinder are connected by bolts.

[0007] Furthermore, the assembled reinforced concrete inner tube is formed by staggered splicing of prefabricated reinforced concrete segments, and adjacent prefabricated reinforced concrete segments are connected by bolts.

[0008] Furthermore, the outer diameter of the steel outer cylinder is 1.2 m; the net distance between the steel outer cylinder and the assembled reinforced concrete inner cylinder is 5 cm; there is a gap between the steel outer cylinder and the assembled reinforced concrete inner cylinder, and the gap is filled with sand.

[0009] Furthermore, the water sensitive sensor is fixed at the water level warning line on the inner wall of the assembled reinforced concrete inner tube.

[0010] The beneficial effects of the utility model are:

[0011] The utility model can not only complete traditional tasks such as pipeline maintenance and sludge removal, but also carry out real-time monitoring of sewage in urban underground drainage pipes. When the sewage water level in the inspection well reaches the water level warning line, the water-sensitive sensor will issue a warning to predict that flood disasters may occur in the city.
