Technical Field

[0001] This utility model relates to the field of junction box technology, specifically to a structure for a municipal road crossing junction box. Background Technology

[0002] A wiring shaft is a type of shaft in a building used for connecting cables, pipes, and other lines. It is usually located in the walls or floor of a building. In a wiring shaft, various lines can be connected and fixed using connectors and accessories to achieve the connection and protection of the lines.

[0003] Since wiring wells are mostly buried underground, even though they are covered with manhole covers, rainwater can still seep into the well body along the edges of the covers during heavy rains, affecting the safety of the internal circuits.

[0004] Therefore, it is necessary to invent a municipal road crossing connection well structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for municipal road crossing connection wells to solve the problem that rainwater can seep into the well body along the edge of the well cover, affecting the safety of the internal circuits.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal road crossing connection well structure, comprising an original soil base layer, a foundation pit being formed on the surface of the original soil base layer, and a connection well body being set inside the foundation pit. The connection well body includes a support pad layer, a sump pit, an inner well body, an outer well body, a sump trough, an iron grate, a fixing slot, a drainage pipe, a wire protection pipe, a waterproof membrane layer, and a waterproof coating layer. The inner well body, the outer well body, and the support pad layer are integrally cast with concrete. A fixing slot is formed at the inner edge of the upper end of the outer well body, and a manhole cover plate is engaged inside the fixing slot.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model provides, for example Figure 1 and Figure 2 The structure of a municipal road crossing connection well shown includes an original soil base 1, on the surface of which a foundation pit is formed. Inside the foundation pit, a connection well body 2 is set. The connection well body 2 includes a support pad 21, a sump 22, an inner well body 23, an outer well body 24, a sump 25, an iron grate 26, a fixing slot 27, a drainage pipe 28, a wire protection pipe 29, a waterproof membrane layer 210, and a waterproof coating layer 211. The inner well body 23, the outer well body 24, and the support pad 21 are integrally cast with concrete. A fixing slot 27 is formed at the inner edge of the upper end of the outer well body 24. A manhole cover plate 3 is clamped inside the fixing slot 27. The upper surface of the support pad 21, located between the outer well body 24 and the side wall of the foundation pit, is filled with a medium-coarse sand backfill layer 11. The upper end of the medium-coarse sand backfill layer 11 is filled with a backfill stone powder layer 12. A sidewalk pavement 13 is laid on the upper side of the backfill stone powder layer 12.

[0032] The edge of the support pad 21 extends to the outside of the outer well body 24 to improve its support strength and stability of the connection well body 2. During the installation of the connection well body 2 under the sidewalk, a pit with a diameter not less than the outer diameter of the support pad 21 is first excavated at the designated location. Then, the connection well body 2 is placed directly inside the pit. After adjusting the position, a medium-coarse sand backfill layer 11 is filled between the outer well body 24 and the inner wall of the pit and compacted to a density of 95%. Then, a backfill stone powder layer 12 is filled on the upper end of the medium-coarse sand backfill layer 11. Finally, the sidewalk pavement 13 is laid on the upper part of the backfill stone powder layer 12.

[0033] In addition, the construction steps for installing the main body 2 of the connection well under the green belt are basically the same as those for installing the sidewalk. The difference is that during the subsequent backfilling process, green planting soil is laid on the upper side of the medium-coarse sand backfill layer 11, and then the green belt is planted on the upper side of the green planting soil.

[0034] See Figures 2 to 4 The water collection pit 22 is located at the center of the support pad 21. The upper end of the water collection pit 22 is clamped with an iron grate 26. A water collection trough 25 is provided between the inner well body 23 and the outer well body 24. The lower end of the water collection trough 25 and the side of the water collection pit 22 are fixedly connected with drainage pipes 28. The front and rear sides and the left and right sides of the inner well body 23 and the outer well body 24 are fixedly connected with wire protection pipes 29. The inner wall of the outer well body 24 is covered with a waterproof membrane layer 210. The inner and outer surfaces of the inner well body 23 and the surface of the waterproof membrane layer 210 are coated with a waterproof coating layer 211.

[0035] Specifically, the drainage pipe 28 and the wiring protection pipe 29 are integrally cast with the inner well body 23, the outer well body 24 and the support pad layer 21 to improve the waterproofness of the interface. After the wiring well body 2 is installed, the externally embedded drainage pipe 28 and wiring protection pipe 29 are connected to the drainage pipe 28 and wiring protection pipe 29 on the surface of the wiring well body 2 using connectors. The external drainage pipe 28 is connected to the nearest rainwater well. The waterproof membrane layer 210 and the waterproof coating layer 211 are laid after the wiring well body 2 is cast and can be directly installed on site, effectively improving the convenience of installation.

[0036] Meanwhile, in actual use, the conduit 29 runs directly from the outside of the outer well body 24 to the inside of the inner well body 23, and the wiring is directly connected inside the inner well body 23. When it rains, the manhole cover 3 first blocks the rainwater, preventing it from entering the inner well body 23 and the outer well body 24. When a small amount of rainwater seeps in from the edge gaps of the manhole cover 3, it will first collect in the water collection trough 25 between the inner well body 23 and the outer well body 24, and then drain into the rainwater well through the drain pipe 28. Under the action of the waterproof coating layer 211, rainwater is prevented from seeping into the inside of the inner well body 23. When a small amount of rainwater seeps into the inside of the inner well body 23, it will also collect in the water collection pit 22, preventing damage to the wiring inside the inner well body 23 and improving the safety of the circuit. In daily use, the waterproof membrane layer 210 also prevents moisture in the soil from seeping into the inside of the outer well body 24, keeping the inside of the wiring well body 2 dry.

[0037] The working principle of this utility model is as follows: By setting the wiring well body 2 with inner and outer layers, the wiring part is set inside the inner well body 23, and the outer well body 24 plays a protective role to prevent groundwater from seeping in. At the same time, rainwater seeping in from the top will be collected in the water collection tank 25. When the amount of rainwater is too large and seeps into the inner well body 23, it will also be collected in the water collection pit 22, which effectively improves the safety of the pipeline. At the same time, by integrally casting the support pad 21, inner well body 23, outer well body 24, drainage pipe 28 and wiring protection pipe 29, the connection strength between the structures is improved, the convenience of installation is improved, and the construction efficiency is improved.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
