[0030] Reference Figure 1 , Figure 2 The embodiments of this application provide a rainwater delay regulation system that can be used for both normal and emergency situations, including: a pre-treatment pond 1, a main pond 3, and an overflow well 4;
[0031] The pre-treatment pond 1 is located at the inlet end of the main pond 3, and an isolation weir 2 is provided between the pre-treatment pond 1 and the main pond 3; an inlet pipe 11 is provided at the inlet end of the pre-treatment pond 1.
[0032] Overflow well 4 is located at the outlet end of main pond 3; water outlet pipe 41 is installed on the bottom side wall of overflow well 4;
[0033] The overflow well 4 is provided with at least a first overflow outlet 42 and a second overflow outlet 43 from bottom to top on the side wall near the main pond 3; the height of the first overflow outlet 42 is higher than the bottom of the main pond 3; and the height of the first overflow outlet 42 is higher than the bottom of the overflow well 4.
[0034] Specifically, the water inlet pipe 11 at the water inlet end of the pre-set pond 1 can be connected to an upstream facility, a drainage end water system, or a municipal pipe network, according to actual needs.
[0035] The pre-set pond 1 is used to deposit larger particles or garbage, so as to prevent too much silt or garbage from entering the main pond 3 area and causing soil compaction. It can be understood that gravel 12 can be arranged at the bottom of the pre-set pond 1, and an energy dissipation baffle 13 can also be arranged, so that the deposition effect of larger particles or garbage is better.
[0036] The first overflow port 42 and the second overflow port 43 can be composed of a plurality of arranged through holes, or can be a horizontally arranged rectangular port, or can be other forms of water discharge holes.
[0037] The height of the first overflow port 42 and the second overflow port 43 is set according to actual needs. For example, the first overflow port 42 can be set according to the water level line of the annual runoff total amount control rate, and is set to be at the same horizontal line as the water level line of the annual runoff total amount control rate. For example, the second overflow port 43 can be set according to the 10-year adjusted water level line, and is set to be at the same horizontal line as the 10-year adjusted water level line. It can be understood that the height of the overflow well 4 can be set according to the 30-year adjusted water level line, and is set to be at the same horizontal line as the 30-year adjusted water level line. It can also be understood that the height of the pond body of the whole flat and rapid dual-purpose rainwater delay regulating system can be set according to the 50-year adjusted water level line, and is set to be at the same horizontal line as the 50-year adjusted water level line.
[0038] It can also be understood that other overflow ports can also be arranged on the side wall of the overflow well according to the actual needs of the adjusted water level line.
[0039] It can also be understood that steps can be formed between the overflow ports.
[0040] The main pond 3 is used to infiltrate the rainwater after the pre-set pond 1 deposition and to drain the excess rainwater into the overflow well 4. It can be understood that when the water level of the rainwater entering the main pond 3 is below the annual runoff total amount control rate control water level line, the rainwater is infiltrated; when the water level of the rainwater entering the main pond 3 is higher than the annual runoff total amount control rate control water level line, the rainwater is drained into the overflow well 4 through the first overflow port 42, and the rainwater drained into the overflow well 4 is drained through the water outlet pipe 41. The water outlet pipe 41 can be connected to a municipal pipe network or other downstream facilities for treating rainwater and sewage.
[0041] The rainwater delay adjustment system for both flat and rapid use provided by the embodiment of the application can prolong the residence time of part of the runoff (for example, 24h-72h), that is, it can cope with the rainfall in normal times and the discharge of heavy rain occurring once in several decades.
[0042] In one embodiment, the overflow well 4 is provided with the first grid 5 on one side close to the main pond 3. The first grid 5 can prevent the silt and particles in the rainwater from entering the overflow well 4.
[0043] In one embodiment, the rainwater delay adjustment system for both flat and rapid use further comprises a micro pool 6.
[0044] The micro pool 6 is arranged between the water outlet end of the main pond 3 and the overflow well 4, and the bottom of the micro pool 6 is lower than the bottom of the overflow well 4.
[0045] A siphon pipe 7 is arranged between the micro pool 6 and the overflow well 4.
[0046] Specifically, the micro pool 6 is a small concave pool arranged in front of the overflow well 4, which prevents the runoff from being discharged when the first overflow port 42 is blocked. The siphon pipe 7 and the micro pool form an inverted siphon structure, rainwater can be discharged into the overflow well 4 through the siphon pipe 7 and then discharged through the water outlet pipe 41.
[0047] In one embodiment, the micro pool 6 is provided with the second grid 8, one end of the second grid 8 is arranged at the water outlet end of the main pond 3, and the other end of the second grid 8 is arranged at the top end of the overflow well 4. The second grid 8 is used to prevent the silt and particles in the rainwater in the main pond 3 from entering the micro pool 6.
[0048] In one embodiment, the top end of the overflow well 4 is provided with the third grid 9. The third grid 9 is used to prevent the surrounding impurities from entering the overflow well 4, and can also prevent the impurities in the rainwater occurring once in 30 years from entering the overflow well 4.
[0049] In one embodiment, the bottom of the main pond 3 is provided with a flow guide groove 31, one end of the flow guide groove 31 is arranged at the isolation weir 2, and the flow guide groove 31 is lower than the main pond 3.
[0050] Specifically, when the runoff from the pre-pond 1 flows into the main pond 3, the small runoff at the beginning is relatively dirty, and the flow rate of the runoff can be reduced through the flow guide groove 31, so that the silt and other pollution particles carried in the runoff are deposited in the flow guide groove, which is convenient for cleaning in the later period. The later guided rainwater is relatively clean, and can flow over the flow guide groove and infiltrate in the main pond 3.
[0051] In addition, the flow guide groove 31 can guide and concentrate the runoff formed by small and medium rainfall, and the rainwater in the flow guide groove is uniformly overflowed to the main pond 3 for storage and infiltration, so that the rainwater cannot enter the main body area of the system or flow along the designed runoff route.
[0052] In one embodiment, the diversion groove 31 is made of hard concrete structure, which is convenient for cleaning and maintaining the bottom sediment sludge.
[0053] In one embodiment, the isolation weir 2 is provided with a diversion port 21 corresponding to the diversion groove 31. The diversion port 21 can accurately guide the overflow rainwater in the pre-pond 1 into the diversion groove 31.
[0054] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
