Description

Technical Field

[0001] This invention relates to the field of integrated utility tunnel technology, and in particular to an underground integrated utility tunnel for rainwater storage in sponge cities. Background Technology

[0002] Integrated utility tunnels are underground urban pipeline corridors, essentially tunnel spaces built beneath the city to integrate various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage. They are equipped with dedicated maintenance ports, hoisting ports, and monitoring systems, and are subject to unified planning, design, construction, and management. They are vital infrastructure and a "lifeline" for ensuring the operation of cities. In recent years, major cities have been prone to urban flooding during the rainy season due to torrential rains. The main reason is that the cross-sectional area of ​​urban sewage pipes is fixed and cannot be adjusted, preventing rainwater from quickly entering the sewage pipes during heavy rains, causing rainwater to accumulate on the roads. Existing technologies utilize the space of underground utility tunnels for rainwater collection and storage. For example, patent CN113152519B discloses an underground integrated utility tunnel for smart city construction, including a main tunnel structure, drainage wells, and box-type water storage tanks. The drainage wells are installed on one side of the main tunnel structure and connected to the ground, while the box-type water storage tanks are installed on one side of the main tunnel structure and connected to the drainage wells. By rationally zoning existing integrated utility tunnels and coordinating with rainwater collection mechanisms, rainwater is absorbed, stored, infiltrated, and purified during rainfall. When needed, the stored water is "released" and utilized, enhancing flood prevention in the corresponding areas and promoting comprehensive rainwater utilization, further alleviating the pressure of urban flooding. At the same time, the rainwater in the rainwater collection chamber can be used as municipal water for greening, road washing, dust suppression, etc. Although a water storage tank is set on one side of the utility tunnel, it occupies too much space and the water treatment is simple. Summary of the Invention

[0003] The purpose of this invention is to provide an underground integrated pipe gallery for rainwater storage in sponge cities, thereby solving the aforementioned technical problems.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-2 As shown, an underground integrated pipe gallery for rainwater storage in sponge cities includes a storage pipe gallery box culvert 1 and a water storage pipe gallery box culvert 2. Several water storage pipe gallery box culverts 2 are arranged side by side to form a water storage pipe gallery body, and a storage pipe gallery box culvert 1 is arranged between adjacent water storage pipe gallery bodies.

[0022] Both the regulating pipe gallery box culvert 1 and the water storage pipe gallery box culvert 2 include an upper functional area and a lower treatment area. The lower treatment area includes an inlet area 3, a sedimentation area 4 and an outlet area 5 arranged in sequence. The inlet area 3 of the regulating water treatment area is connected to the inlet channel 16. A filter plate 17 is installed in the inlet channel 16 to perform preliminary filtration of rainwater.

[0023] The water storage tunnel box culvert 1 and the water storage tunnel box culvert 2 have similar structures, such as Figure 3 As shown, the upper functional area of ​​the regulating pipe gallery box culvert 1 includes a first flood control culvert 11. Above the first flood control culvert 11, a first power culvert 12, a first water supply culvert 13, and a first gas culvert 14 are sequentially arranged. A first flood control through-hole 15 is provided between the first power culvert 12, the first water supply culvert 13, and the first gas culvert 14 and the flood control culvert. A water outlet channel 18 is provided on the first water supply culvert 13. Figure 4 As shown, the upper functional area of ​​the water storage pipe gallery box culvert 2 includes a second flood control culvert 21. A second power culvert 22, a second water supply culvert 23, and a second gas culvert 24 are sequentially arranged above the second flood control culvert 21. A second flood control through hole 25 is arranged between the second power culvert 22, the second water supply culvert 23, the second gas culvert 24 and the second flood control culvert 21. A water storage capsule 8 is installed in the second water supply culvert 23. The sedimentation area 4 in the water storage pipe gallery box culvert 2 is also equipped with inclined plate 47.

[0024] like Figure 5 As shown, a water storage pump 7 is installed in the effluent zone 5 of the water storage treatment area. The water storage pump 7 is connected to the water storage capsule 8 in the water storage pipe gallery culvert 2 through a pipeline. A call pump 9 is installed in the water storage capsule 8. The call pump 9 is connected to the effluent channel 18 of the water storage pipe gallery culvert 1 through a pipeline. Several parallel sludge discharge troughs 41 are provided at the bottom of the sedimentation zone 4. The sludge discharge troughs 41 are trapezoidal. Sludge discharge pipes 42 are installed in the sludge discharge troughs 41. The sludge discharge pipes 42 are connected to sludge discharge pumps 43. The sludge discharge end of the sludge discharge pump 43 is fixed at the port of the water inlet channel 16 through the water inlet zone 3 and the water inlet channel 16. The sedimentation zone 4 is equipped with an inlet baffle 44 and an outlet baffle 45. One end of the inlet baffle 44 is connected to the top of the inner side of the lower treatment zone, and the other end forms an inlet with the bottom of the inner side of the lower treatment zone. One end of the outlet baffle 45 is connected to the bottom of the inner side of the lower treatment zone, and the other end forms an outlet with the top of the inner side of the lower treatment zone. An inclined plate frame 47 is installed between the inlet baffle 44 and the outlet baffle 45 to improve the sedimentation effect. The inclined plate frame 47 includes a fixed filter plate 46, and several inclined plates 47 are arranged side by side below the fixed filter plate 46. Utilizing the laminar flow principle, the water flows between the plates with a very small hydraulic radius, exhibiting a laminar flow state, which is extremely beneficial for sedimentation. This increases the area of ​​the sedimentation tank, thereby improving sedimentation efficiency. It also shortens the particle settling distance, greatly reducing the sedimentation time. The re-agglomeration of flocculent particles within the inclined plate 47 promotes further particle growth, further improving sedimentation efficiency. A lifting device 10 is installed on the outlet baffle 45, and a suction nozzle 101 is installed on the lifting device 10. The suction nozzle 101 is connected to the water storage pump 7 through a pipe. A water level sensor 102 is installed on the fixed filter plate 46, and the water level sensor 102 is electrically connected to the lifting device 10. The height of the suction nozzle 101 is adjusted according to the actual water level. One-way valves are installed in both the first flood control through-hole 15 and the second flood control through-hole 25. One-way valves are also installed between the first flood control culvert 11 and the lower treatment area, and between the second flood control culvert 21 and the lower treatment area. A through-hole 19 is installed between the first flood control culvert 11 and the lower treatment area. The pipe of the water storage pump 7 passes through the through-hole 19 (sealed with sealant) and connects to the water storage capsule 8. Figure 6As shown, the water storage capsule 8 includes a flexible capsule body 81 (made of rubber). An upper protective plate 82 and a lower protective plate 83 are respectively provided at the top and bottom of the flexible capsule body 81. Support plates 84 are provided at both ends of the upper protective plate 82 to prevent damage caused by squeezing the flexible capsule body 81. A first protective plate 85 and a second protective plate 86 are provided on both sides of the flexible capsule body 81. One end of the first protective plate 85 is hinged to the upper protective plate 82, and the other end of the first protective plate 85 is hinged to one end of the second protective plate 86 via a torsion spring. The other end of the second protective plate 86 is hinged to the lower protective plate 83. This protects the flexible capsule body 81 and improves its service life. The water storage capsule 8 enhances water storage capacity. Rainwater enters the sedimentation zone 4 through the inlet channel 16 and the inlet area 3 for sedimentation. After sedimentation, the upper clear water is drawn into the water storage capsule 8 by the water storage pump 7 for storage. When water needs to be used, it is drawn out by the dispensing pump 9 for irrigation, dust removal, etc. An I-beam support frame 6 is provided at the bottom of the lower treatment area to improve support strength.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
