The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0021] The present application embodiment provides a pipeline maintenance structure under the road, such as Figures 1 to 3 As shown, the pipeline maintenance structure under the road includes a pavement structure 10, a tunnel structure 20, a support structure 30 and at least one second maintenance shaft 50.

[0022] The tunnel structure 20 is located below the pavement structure 10 and is used to accommodate pipes and allow personnel to pass through. The support structure 30 is located below the tunnel structure 20 and is provided with a first inspection well 40; wherein the first inspection well 40 corresponds to the connection point of the pipe. At least one second inspection well 50 is located beside the pavement structure 10 and passes through the support structure 30.

[0023] For example, in Figure 1 In the pipeline maintenance structure under the road shown, two second maintenance wells 50 are respectively located on both sides of the road surface structure 10, and maintenance personnel can enter any second maintenance well 50 according to actual conditions.

[0024] When it is necessary to inspect the pipeline located in the tunnel structure 20, the maintenance personnel enter the second inspection well 50, and simultaneously enter the first inspection well 40 from the inside of the tunnel structure 20. The location of the first inspection well 40 corresponds to the connection of the pipeline, and the maintenance personnel located in the first inspection well 40 can inspect the connection of the pipeline; when the pipeline is inspected, the maintenance personnel come out of the first inspection well 40 and return to the road surface through the tunnel structure 20 and the second inspection well 50. Therefore, when the pipeline located in the tunnel structure 20 leaks or other situations require inspection, there is no need to dig the road. The maintenance personnel can directly enter the pipeline inspection structure under the road to inspect the pipeline, and the vehicle traffic on the road surface structure 10 will not be affected during the inspection.

[0025] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the tunnel structure 20 includes two supporting walls 21 and a plurality of beams 22 .

[0026] The two supporting walls 21 are arranged in parallel, and a maintenance passage for personnel to pass through is formed between the two supporting walls 21. For example, the supporting wall 21 can be formed by brickwork, such as Figure 2 As shown, of course, the supporting wall 21 can also be formed by pouring concrete.

[0027] A plurality of cross beams 22 are arranged at intervals, perpendicular to the two supporting walls 21, and both ends of each cross beam 22 are connected to the two supporting walls 21 to support the pavement structure 10. Through the above structure, the plurality of cross beams 22 disperse and transfer the load formed by the pavement structure 10 to the two supporting walls 21, and together with the two supporting walls 21 form a stable frame structure to ensure the safety of personnel inside the tunnel. The cross beam 22 may be a steel beam or a reinforced concrete beam.

[0028] Furthermore, both ends of each cross beam 22 are respectively inserted into the two supporting walls 21, so that the ends of each cross beam 22 can be firmly and stably connected to the supporting walls 21. Specifically, slots or holes are reserved at the tops of the two supporting walls 21, and both ends of the cross beam 22 are inserted into the slots or holes reserved in the two supporting walls 21.

[0029] The tunnel structure 20 is not limited to the above-mentioned structural form. In other embodiments of the present application, the tunnel structure 20 can also be other structural forms. For example, the tunnel structure 20 includes a plurality of prefabricated concrete pipe galleries connected in sequence, and a through hole is opened at the wellhead of the first inspection shaft 40, and maintenance personnel can enter the first inspection shaft 40 through the through hole.

[0030] like Figure 3 As shown, in the embodiment of the present application, the support structure 30 includes a soil foundation structure 31 and a plurality of reinforcement pipe columns 32. A plurality of reinforcement pipe columns 32 are arranged in an array in the soil foundation structure 31. The reinforcement pipe columns 32 can enhance the bearing capacity and stability of the soil foundation structure 31, prevent the soil from deforming or collapsing due to excessive load, and make the support structure 30 have a good supporting capacity as a whole. Among them, the reinforcement pipe columns 32 can be formed by concrete pouring; specifically, first, a plurality of pouring holes are drilled on the soil foundation structure 31, and then concrete is poured in the plurality of pouring holes to form the reinforcement pipe columns 32.

[0031] The supporting structure 30 is not limited to the above-mentioned structural form. In other embodiments of the present application, the supporting structure 30 may also be other structural forms. For example, the supporting structure 30 is a reinforced concrete structure as a whole.

[0032] Continue to refer to Figure 1 The inner wall of the first inspection well 40 is provided with a reinforcement ring 41, and the reinforcement ring 41 compresses the support structure 30. For example, the reinforcement ring 41 can be a steel ring or a concrete structure. The reinforcement ring 41 compresses the support structure 30 through its own rigidity and close contact with the support structure 30, and this compressing effect helps to improve the overall stability of the support structure 30.

[0033] like Figure 1 As shown, in the embodiment of the present application, a drainage structure 51 is provided at the bottom of the second inspection well 50. When water on the pavement structure 10 flows into the second inspection well 50, the water is discharged from the drainage structure 51. Specifically, the drainage structure 51 is a drainage channel connected to the sewer pipe.

[0034] like Figure 1 and Figure 2As shown, the pipeline maintenance structure under the road provided by the embodiment of the present application also includes a waterproof layer 11 arranged at the bottom of the pavement structure 10. The material of the waterproof layer 11 can be polyethylene film, asphalt waterproof roll material, polymer waterproof coating, etc.

[0035] The waterproof layer 11 can prevent moisture from penetrating from under the pavement structure 10 into the tunnel structure 20 or the supporting structure 30, which is crucial for maintaining the stability of the pipeline maintenance structure under the road and extending its service life, because the penetration of moisture may cause problems such as soil softening, structural corrosion and reduced bearing capacity.

[0036] like Figure 1 As shown, the pipeline maintenance structure under the road provided by the embodiment of the present application further includes a ventilation device 60, which is arranged inside the tunnel structure 20 and is used to ventilate the first inspection well 40 and the two second inspection wells 50. The ventilation device 60 can effectively discharge harmful gases, moisture and odors inside the tunnel structure 20, and introduce fresh air, thereby improving the air quality inside the first inspection well 40 and the two second inspection wells 50; and by using the ventilation device 60 to ventilate the inside of the tunnel structure 20, the first inspection well 40 and the second inspection well 50, the temperature and humidity inside the pipeline maintenance structure under the road can be reduced, and the problems of structural corrosion, mold growth and the like caused by humidity and high temperature can be reduced. For example, the ventilation device 60 can be an axial flow fan.

[0037] Continue to refer to Figure 1 In the embodiment of the present application, two second inspection wells 50 are respectively located on both sides of the pavement structure 10, and the ventilation device 60 is located above the first inspection well 40, and the air inlet side and the air outlet side of the ventilation device 60 are respectively facing the two second inspection wells 50; the tunnel structure 20 also includes a baffle 90, which is located on the air inlet side of the ventilation device 60 and connected to one of the crossbeams 22; the baffle 90 extends downwardly at an angle, and the baffle 90 gradually approaches the ventilation device 60 from top to bottom. When the ventilation device 60 is turned on, the outside air enters from one of the second inspection wells 50, and the air inside the pipeline inspection structure under the road is discharged from the other second inspection well 50. The air entering from the outside will hit the baffle 90 and change direction. After changing direction, the air flows to the location of the first inspection well 40, and then bypasses the baffle 90 and is discharged through the other second inspection well 50. Therefore, from the air flow process described above, it can be seen that the baffle 90 changes the flow direction of the air, allowing fresh air from the outside to flow to the location of the first inspection shaft 40, thereby allowing the maintenance personnel located in the first inspection shaft 40 to breathe fresh air, further ensuring the safety of the maintenance personnel.

[0038] like Figure 1 and Figure 2As shown, the road pipeline maintenance structure provided by the embodiment of the present application also includes a lighting device 70, which is installed at the bottom of the road surface structure 10 and is used to illuminate the interior of the tunnel structure 20 and the first inspection shaft 40. The maintenance personnel turn on the lighting device 70 before entering the tunnel. The lighting device 70 can provide sufficient light so that the maintenance personnel can clearly see the interior of the tunnel structure 20 and the first inspection shaft 40, thereby ensuring the safety and accuracy of the maintenance work. For example, the lighting device 70 can be an LED lamp, a fluorescent lamp, etc.

[0039] like Figure 1 As shown, the under-road pipeline maintenance structure provided in the embodiment of the present application further includes a manhole cover 80 , which is installed at the wellhead of the second inspection well 50 .

[0040] The manhole cover 80 can close the wellhead of the second inspection well 50 to prevent people, vehicles and debris from falling into the second inspection well 50, thereby ensuring the safety of the road and smooth passage. In addition, the manhole cover 80 can also reduce the impact of the external environment, such as rain, snow, debris, etc., on the interior of the second inspection well 50.

[0041] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0042] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
