DETAILED DESCRIPTION
[0024] As shown in Figure 1 and Figure 2 , the integrated composite sewage intercepting well comprises:
[0025] The outer ring well 9 is a closed circular inspection well formed by the outer ring well wall 5 and the inner ring well wall 6.
[0026] The inner ring well 10 is a closed cylindrical inspection well formed by the inner ring well wall 6.
[0027] The bottom elevation of the outer ring well 9 is consistent with the bottom elevation of the inner ring well 10, and in some embodiments, the well diameter of the outer ring well 9 is 1000 mm larger than the well diameter of the inner ring well 10.
[0028] The outer ring well 9 is provided with a combined inflow pipe 1, an overflow outflow pipe 2, a water passage hole 7 and a water retaining weir 8. The combined inflow pipe 1 is used to transport sewage or combined sewage to the outer ring well 9; the overflow outflow pipe 2 is located on the opposite side of the combined inflow pipe 1 and is used to realize overflow of water in the outer ring well 9; the water passage hole 7 is used to connect the outer ring well 9 and the inner ring well 10; and the water retaining weir 8 is used to separate the outer ring well 9 and is located between the water passage hole 7 and the combined inflow pipe 1.
[0029] The combined inflow pipe 1 is arranged on one side of the outer ring well wall 5, and the water inflow direction of the combined inflow pipe 1 can be in any direction according to engineering needs. The elevation and pipe diameter of the combined inflow pipe 1 are calculated and valued according to existing engineering data. An overflow outflow pipe 2 is arranged on the opposite side of the combined inflow pipe 1, and the pipe diameter and elevation of the overflow outflow pipe 2 are the same as those of the combined inflow pipe 1.
[0030] The water outlet of the outer ring well 9 enters the inner ring well 10 through the water passing hole 7 on the inner side of the outer ring well 9. The water passing hole 7 is arranged on the inner ring well wall 6, and the center line of the water passing hole 7 is positioned in the direction of rotating 315° clockwise from the center line of the combined water inlet pipe 1. The size of the water passing hole 7 is calculated according to the interception multiple and the interception flow, and the bottom elevation of the water passing hole 7 is 100 mm higher than the bottom of the outer ring well 9.
[0031] The outer ring well 9 is provided with a water retaining weir 8, the top elevation of which is the same as the top elevation of the combined water inlet pipe 1, and the center line of the water retaining weir 8 is positioned in the direction of rotating 337.5° clockwise from the center line of the combined water inlet pipe 1. During use, the sewage or combined sewage passes through the outer ring well wall 5 and enters the outer ring well 9 through the pipeline by gravity flow. When entering, the water flow has a large flow rate, and after impacting on the inner ring well wall 6, it falls to the bottom of the outer ring well, and part of the kinetic energy of the water body is converted into potential energy, causing the liquid level to be obviously higher, forming a water jump. Subsequently, the water flow adjusts the flow state and flows through the water passing hole 7 on the inner ring well wall 6 to enter the inner ring well 10, thereby realizing the function of water drop and energy dissipation.
[0032] The inner ring well 10 is provided with an inner ring well water inlet pipe 3, an inner ring well water outlet pipe 4 and a duckbill valve 11. The upstream sewage flowing into the inner ring well water inlet pipe 3 is discharged to the downstream through the inner ring well water outlet pipe 4. The duckbill valve 11 is made of elastic neoprene rubber and artificial fibers through special processing, and has a shape similar to a duckbill. Under the condition of no pressure on the outside, the duckbill outlet is closed under the elastic action of itself. As the pressure on the outside gradually increases, the duckbill outlet gradually increases, so that the liquid can be discharged at a high flow rate, and the water flow in the inner ring well can be prevented from flowing into the outer ring well. The diameter of the inner ring well 10 is determined according to the pipe diameter of the inner ring well water outlet pipe 4, and the bottom elevation of the inner ring well 10 is determined according to the bottom elevation of the inner ring well water outlet pipe 4 minus 100 mm.
[0033] The pipe diameter and elevation of the inner ring well water inlet pipe 3 and the pipe diameter and elevation of the inner ring well water outlet pipe 4 are determined according to the actual needs of the project and the water elevation of the upstream and downstream. The inner ring well water inlet pipe 3 is not limited to the direction of the water flow, and can be symmetrically arranged with the inner ring well water outlet pipe 4, or can be arranged at an obtuse angle. In an embodiment, the combined sewage of the outer ring well 9 is received by the water passing hole 7 outside the water passing hole 7, and the combined sewage enters the inner ring well 10 through the water passing hole 7, and is then discharged to the municipal sewage treatment plant through the inner ring well water outlet pipe 4.
[0034] Furthermore, a float valve 21 is installed on the outside of the water passage 7. The float valve is the same size as the water passage 7. The function of the float valve is to control the flow rate of combined sewage discharged from the outer ring well 9 according to the water level of the inner ring well 10. The main function of the float valve is during the rainy season. During the dry season, the float valve is fully open, and the domestic sewage generated by residents enters the inner ring well 10 from the outer ring well 9, and is then discharged to the downstream sewage treatment plant. In the early stage of rainfall, the runoff from the ground carries pollutants such as dust and mud. At this time, the pollution level of the combined sewage is relatively high, the rainfall is small, and the water levels of the inner ring well 10, the inner ring well inlet pipe 3, and the inner ring well outlet pipe 4 are all low. At this time, the float valve is also in the fully open state. In the later stage of rainfall, the ground is relatively dry after being washed by rainwater. The combined sewage is relatively clean and has a low level of pollution. At this time, the rainfall increases, and the water levels in the inner ring well 10, the inner ring well inlet pipe 3, and the inner ring well outlet pipe 4 rise until they reach the water level required to open the float valve. At this time, the water passage 7 closes, and the relatively clean combined sewage stagnates in the outer ring well 9. The water level in the outer ring well 9 rises, and the overflow outlet pipe 2 plays its role, discharging the relatively clean combined sewage through the overflow outlet pipe 2 into a receiving water body with a certain water environment capacity, thus avoiding the outer ring well from overflowing and causing ground flooding.
[0035] During use, the combined sewage from the outer ring well 9 falls into the inner ring well 10 through the water passage 7 in the inner ring well wall 6, and merges with the upstream sewage flowing in from the inner ring well inlet pipe 3 in the inner ring well, and is discharged to the downstream sewage treatment plant through the inner ring well outlet pipe 4.
[0036] like Figure 3 and Figure 4 As shown, the bottom of the inner ring well inlet pipe 3 and the inner ring well outlet pipe 4 are higher than the bottom of the inner ring well 10, the top of the inner ring well inlet pipe 3 and the inner ring well outlet pipe 4 are lower than the bottom of the outer ring well 9, the bottom of the water passage hole 7 is higher than the bottom of the outer ring well 9, the top of the water passage hole 7 is lower than the bottom of the combined inlet pipe 1 and the overflow outlet pipe 2, and the combined inlet pipe 1 and the overflow outlet pipe 2 are at the same height.
[0037] As can be seen, the multi-functional inspection well has two walls, dividing it into two parts: the outer ring well serves as the inlet area, overflow area, and energy dissipation area, while the inner ring well serves as the connection area, interception area, and outlet area. The combined inlet pipe first enters the outer ring inspection well according to the direction of the incoming water. Upon impact and friction with the inner wall of the inspection well, some kinetic energy is dissipated, and the water falls to the bottom of the outer ring well. It then flows through the outer ring well channel for a full circle to the end through-hole, thus eliminating the energy carried by the water entering the inspection well from the combined pipe. Simultaneously, an overflow outlet pipe with the same diameter and elevation as the combined inlet pipe is installed in the outer ring well to achieve the overflow function of the inspection well during rainfall. The combined inlet water flows through the through-hole and falls into the inner ring of the inspection well. The inner ring is connected to the inlet and outlet pipes of the main drainage pipe, completing the connection and outlet functions of the inspection well. In summary, this multi-functional inspection well can effectively prevent waterlogging, save land, and reduce investment.
[0038] As Figure 5 shown, the float valve 8, structure includes slide rail, float 14 and slide plate 16, the slide plate 16 is installed on the slide rail by sliding block, outside fixedly installed with float 14, inside fixedly installed with sealing ring 15 corresponding to water hole 7. With the water level of outer ring well 9 rises or falls, float 14 drives slide plate 16 to move upwards or downwards, in turn, blocks water hole 7.
[0039] The slide rail includes left slide rail 12 and right slide rail 13 installed on the left and right sides of water hole 7, the left side of slide plate 16 is fixedly connected with the sliding block of left slide rail 12, the right side is fixedly connected with the sliding block of right slide rail 13, can move up and down along the slide rail. To prevent slide plate 16 from sliding out of the slide rail, the upper and lower ends of the slide rail are both installed with limit block.
[0040] The upper and lower ends of left slide rail 12 are respectively installed with first stop block 17 and second stop block, and the upper and lower ends of right slide rail 13 are respectively installed with third stop block 19 and fourth stop block 20. Further, when the water level drops, in order to make slide plate 16 descend smoothly, a metal pendant can be installed below slide plate 16, pull down the slide plate, when float 14 is affected by buoyancy, can drive slide plate 16 and pendant to move upwards.
[0041] The utility model discloses a traditional intercepting well, drop well, three-way connecting well are merged into an inspection well, and then save the land, reduce investment.Drop energy dissipation effect can avoid the water flow rate too high directly into the present situation well, cause the scouring of downstream pipeline, avoid the drought season sewage direct drop in the present situation well causes the aeration flow state.And intercepting function can limit the relatively clean combined sewage in the outer ring well in rainy season and flow, avoid entering the inner ring well to cause the greater pressure of drainage and water supply pipe network operation.
