Description

Technical Field

[0001] The utility model belongs to the technical field of drainage, and in particular relates to an adjustable unorganized drainage pit device. Background Art

[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 unorganized drainage pit device, which prevents water accumulation in the equipment foundation by adjusting the water inlet height of the drainage pipe.

[0025] 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.

[0026] like Figure 1 As shown, the adjustable unorganized drainage pit device of this embodiment includes a sump 11 arranged on the bottom surface of the equipment foundation 10, and an outdoor drainage pipe 12 is arranged in the sump 11. The drainage pipe 12 passes through the equipment foundation 10 and is used to drain water to low-lying areas. Specifically, Figure 2 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.

[0027] The water inlet of the outdoor drain pipe 12 in this embodiment is connected to the indoor drain pipe 13. The indoor drain pipe 13 is a flexible hose, specifically an EVA corrugated tube. This allows for easy adjustment of the shape and position of the indoor drain pipe 13. Specifically, under normal drainage conditions, the indoor drain pipe 13 can be positioned within the sump 11. When the groundwater level is higher than the top elevation of the foundation slab, the water inlet of the indoor drain pipe 13 is positioned above the outdoor floor 20.

[0028] In a preferred implementation of this embodiment, the sump 11 is covered with a grate 14, which is preferably an iron grate. The grate 14 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.

[0029] In the preferred embodiment of this embodiment, a water stop ring 15 is provided on the outdoor drain pipe 12, which is cast within the equipment foundation 10. The water stop ring 15 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.

[0030] In a preferred implementation of this embodiment, a water penetration pit 21 is provided at the water outlet of the outdoor drainage pipe 12 . The water penetration pit 21 is made of graded gravel to prevent the outlet of the outdoor drainage pipe 12 from being blocked by the outdoor soil layer 22 .

[0031] In the preferred embodiment of this embodiment, a retaining ring 16 is provided on the equipment foundation 10 for securing the indoor drain pipe 13. Furthermore, the height of the retaining ring 16 is higher than the outdoor floor 20. This allows the indoor drain pipe 13 to be secured to the retaining ring 16 when the water inlet height is required to be higher than the outdoor floor 20, thereby preventing outdoor groundwater from seeping into the equipment foundation 10.

[0032] The adjustable unorganized drainage pit device of this embodiment can drain the accumulated water in the sump 11 to a low-lying area through the outdoor drainage pipe 12 by arranging an outdoor drainage pipe 12 passing through the equipment foundation 10 in the sump 11; by connecting the indoor drainage pipe 13 to the water inlet of the outdoor drainage pipe 12, and using a hose for the indoor drainage pipe 13, so that: when the groundwater level is lower than the top elevation of the foundation plate, the indoor drainage pipe 13 is located in the sump 11, and the accumulated water in the sump 11 can be drained to a low-lying area through the indoor drainage pipe 13 and the outdoor drainage pipe 11; when the groundwater level is higher than the top elevation of the foundation plate, the water inlet height of the indoor drainage pipe 13 is higher than the outdoor floor 20, so that the groundwater outside the equipment foundation cannot enter the equipment foundation 10 through the outdoor drainage pipe 12 and the indoor drainage pipe 13. In summary, the adjustable unorganized drainage pit device of this embodiment can adjust the water inlet height of the indoor drainage pipe 13 according to the changes in the height of the outdoor groundwater level, so that normal drainage can be achieved in seasons with less rain, and in seasons with more rain, it can prevent groundwater from seeping into the equipment foundation 10, thereby preventing water accumulation in the equipment foundation 10.

[0033] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. The scope of protection of the present invention shall be subject to the claims.
