[0002] As global demand for renewable energy sources grows, the number of new booster stations is increasing. Consequently, the design requirements for related equipment foundations are receiving increasing attention. Most equipment foundations require subsurface support, so they typically utilize box-type raft foundations with drainage sump pits. These sump pits can be designed with either organized or unorganized drainage, depending on the specifications of the booster station, local geological survey conditions, and the extent of the groundwater.
[0003] In organized drainage, a drainage pipe is installed in the sump, connected to a pump, and water is pumped out based on the water level within the foundation. This method offers the advantages of manual control and ease of operation. However, organized drainage requires the installation of a sump, drainage pipes, pumps, and foundations, leading to high costs and complex construction.
[0004] In fugitive drainage, sump drains are piped down to a low-lying outlet, offering advantages such as low cost and simple construction. However, in non-arid areas, fugitive drainage can easily lead to water accumulation, especially during the rainy season, resulting in poor drainage and unchangeable drainage. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to provide an adjustable drainage pit device that can be adjusted according to the groundwater level and realize unorganized drainage and organized drainage.
[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0008] When the blocking pipe is connected to the connecting port, the outdoor drainage pipe is connected to the blocking pipe through the connecting port and is separated from the side wall porous pipe; when the blocking pipe is removed from the connecting port, the outdoor drainage pipe is connected to the side wall porous pipe through the connecting port.
[0009] Furthermore, one end of the outdoor drainage pipe extending outside the equipment foundation is closed, the connection port is arranged at the top of the outdoor drainage pipe, and the side wall porous pipe is located in the vertical direction.
[0010] Furthermore, a water seepage pit is provided in the outdoor soil layer, the outdoor drainage pipe and the bottom of the side wall porous pipe are located in the water seepage pit, and the water seepage pit is made of graded crushed stone.
[0011] Furthermore, a water stop ring is provided on the outdoor drainage pipe, and the water stop ring is cast in the equipment foundation.

[0013] Furthermore, the connection port is configured as a threaded connection port, and the blocking tube is threadedly connected to the connection port.
[0014] Furthermore, a sealing rubber pad is provided between the blocking tube and the connecting port.
[0015] Furthermore, when the blocking pipe is connected to the connecting port, the pipe opening of the blocking pipe is higher than the outdoor floor.
[0016] Furthermore, the sump is arranged at the lowest position of the bottom surface of the equipment foundation.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.
[0029] like Figure 1-2 As shown, the adjustable drainage pit device of this embodiment includes a sump 11 provided on the bottom surface of the equipment foundation 10. Specifically, Figure 3 As shown, the sump 11 is set at the lowest position of the bottom surface of the equipment foundation 10. Furthermore, the bottom surface of the equipment foundation 10 has a slope of 0.3%-2% toward the sump 11, preferably a slope of 1%, so that all the accumulated water in the equipment foundation 10 can flow into the sump 11. An outdoor drainage pipe 12 is provided in the sump 11, and the outdoor drainage pipe 12 passes through the equipment foundation and extends into the outdoor soil layer 20. Specifically, a side wall porous pipe 13 is provided in the outdoor soil layer 20, and a sealing pipe 14 is provided in the side wall porous pipe 13. Holes 131 are provided on the side wall of the side wall porous pipe 13 at intervals, as shown in FIG. Figure 4As shown. In this embodiment, the side wall porous tube 13 is fixedly connected to the outdoor drain pipe 12, and the outdoor drain pipe 12 is provided with a connection port 15 that is detachably connected to the blocking tube 14. Specifically, when the blocking tube 14 is connected to the connection port 15, the outdoor drain pipe 12 is connected to the blocking tube 14 through the connection port 15 and is separated from the side wall porous tube 13. At this time, the accumulated water in the sump 11 can only be discharged through the blocking tube 14; when the blocking tube 14 is removed from the connection port 15, the outdoor drain pipe 12 is connected to the side wall porous tube 13 through the connection port 15. At this time, the accumulated water in the sump 11 can be discharged through the holes 131 provided on the side wall porous tube 13.
[0030] Specifically, in this embodiment, the end of the outdoor drain pipe 12 extending outside the equipment base 10 is sealed, and a connection port 15 is provided at the top of the outdoor drain pipe 12. The sidewall porous tube 13 is located in a vertical direction. The sidewall porous tube 13 and the outdoor drain pipe 12 can be integrally provided or welded together. The connection port 15 is located within the lower end of the sidewall porous tube 13. Thus, when the plugging tube 14 is not installed in the sidewall porous tube 13 and the plugging tube 14 and the connection port 15 are not connected, the outdoor drain pipe 12 communicates with the sidewall porous tube 13 through the connection port 15. When the plugging tube 14 is connected to the connection port 15, the outdoor drain pipe 12 communicates with the plugging tube 14, and the outdoor drain pipe 12 is now separated from the sidewall porous tube 13. In this embodiment, the connection port 15 is a threaded connection, and the plugging tube 14 and the connection port 15 are threadedly connected. A sealing rubber gasket is provided between the plugging tube 14 and the connection port 15 to improve sealing performance. In a preferred implementation of this embodiment, when the blocking pipe 14 is connected to the connecting port 15, the pipe mouth of the blocking pipe 14 is higher than the outdoor floor 21. In this way, the accumulated water in the outdoor soil layer 20 cannot enter the equipment foundation 10. At the same time, the blocking pipe 14 can also be conveniently connected to a mobile water pump to regularly pump out the accumulated water in the sump 11 through the mobile water pump.
[0031] In a preferred implementation of this embodiment, a water permeability pit 22 is provided in the outdoor soil layer 20, and the bottom of the outdoor drainage pipe 12 and the side wall porous pipe 13 are located in the water permeability pit 22. The water permeability pit 22 is made of graded gravel, which can prevent the holes 131 set on the side wall of the side wall porous pipe 13 from being blocked by bare soil.
[0032] In a preferred implementation manner of this embodiment, the sump 11 is covered with a grate 16, which is an iron grate. The grate 16 serves as a cover for the sump 11. On the one hand, it can prevent maintenance personnel from stepping into the sump 11, and on the other hand, it can filter out debris to avoid clogging of the sump 11.
[0033] In the preferred embodiment of this embodiment, a water stop ring 17 is provided on the outdoor drain pipe 12, which is cast within the equipment foundation 10. The water stop ring 17 prevents cracks from forming during the casting of the outdoor drain pipe 12, ensuring that water from the sump 11 is discharged only through the outdoor drain pipe 12, thus making the drainage of accumulated water from the equipment foundation 10 controllable.
[0034] The adjustable drainage pit device of this embodiment is achieved by setting an outdoor drainage pipe 12 in the sump 11 that passes through the equipment foundation 10 and extends into the outdoor soil layer 20, and connecting the side wall porous pipe 13 located in the outdoor soil layer 20 and a blocking pipe 14 detachably connected to the outdoor drainage pipe 12 to the outdoor drainage pipe 12. In this way, when the groundwater level is lower than the top elevation of the foundation plate, the blocking pipe 14 is removed from the connecting port 15 of the outdoor drainage pipe 12, and the outdoor drainage pipe 12 is connected to the side wall porous pipe 13 through the connecting port 15. The accumulated water in the sump 11 enters the side wall porous pipe 13 through the outdoor drainage pipe 12, and then is drained to the low-lying area through the holes 131 provided on the side wall porous pipe 13, thereby realizing unorganized drainage. Figure 1 As shown; when the groundwater level is higher than the top elevation of the foundation plate, the plugging pipe 14 is connected to the connecting port 15. At this time, the side wall porous pipe 13 and the outdoor drainage pipe 12 are separated, and the water in the outdoor soil layer 20 cannot penetrate into the equipment foundation 10. At this time, a water pump can be connected to the plugging pipe 14 to regularly drain the accumulated water in the sump 11 to achieve a technical effect similar to organized drainage, such as Figure 2 In summary, the adjustable drainage pit device of this embodiment can be adjusted according to the height change of the outdoor groundwater level and realize unorganized drainage and organized drainage.
