DETAILED DESCRIPTION
[0024] In order to make the technical problem, technical scheme and beneficial effect of the utility model clearer, the utility model is further described in detail in the following with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.
[0025] Embodiment one
[0026] As Figure 1 Indicated, the utility model provides a kind of sewage interception system for closed landscape water body of city park, including first turf 10, footpath 20 and rainwater interception area that are sequentially arranged, rainwater interception area is communicated with closed landscape water body 40 by first pipeline 30, to control surface rainwater runoff pollution, that is, rainwater interception area can collect and preliminarily purify surface rainwater runoff, and when rainwater flows through rainwater interception area, the pollutants such as suspended solids, organic matters and inorganic dust in it are intercepted, so that the pollutants carried in rainwater runoff enter closed landscape water body 40, so that the pollution load of closed landscape water body 40 is reduced, the self-purification ability of underwater vegetation is maintained, and the growth of algae is inhibited.
[0027] As Figure 1 shown in the embodiment, the plane on which the first turf 10 is located is at an angle with the plane on which the walkway 20 is located, that is, the first turf 10 has a slope, which can be designed to be 30°, so that the rainwater can flow more smoothly along the slope direction, which helps to quickly drain the accumulated water on the turf. Of course, in actual design, the slope of the first turf 10 can be designed according to actual needs.
[0028] As Figure 1 shown in the embodiment, the rainwater interception area includes the second turf 50, which is arranged between the walkway 20 and the enclosed landscape water body 40, and the initial rainwater drainage well 60 is arranged in the second turf 50. One side of the initial rainwater drainage well 60 is communicated with the enclosed landscape water body 40 through the first pipeline 30, and the bottom of the initial rainwater drainage well 60 is connected with the flood drainage ditch (not shown in the figure) through the second channel 70. When it rains, the initial rainwater flows into the initial rainwater drainage well 60 through the walkway 20. Since the initial rainwater carries more pollutants, the initial rainwater can be discharged to the flood drainage ditch through the second channel 70, so as to discharge the pollutants (such as suspended solids, organic matter, oil, etc.) into the flood drainage ditch, avoiding the direct entry of high-pollution rainwater into the water body, thereby protecting the water quality of the enclosed landscape water body 40; the middle and later stage rainwater has less pollutants, and the middle and later stage rainwater enters the enclosed landscape water body 40 through the first pipeline 30 of the initial rainwater drainage well 60 to supplement the water quantity of the enclosed landscape water body 40, realizing the rational utilization of rainwater resources, maintaining the normal water level of the enclosed landscape water body 40, meeting the natural flow state of the water body, and helping to improve the self-purification ability and ecological balance of the water body.
[0029] It should be noted that the flood drainage ditch is a flood drainage pipeline of the municipal government, which is convenient for collecting and purifying the initial rainwater.
[0030] As Figure 1 , Figure 2 shown in the embodiment, the first pipeline 30 includes the first horizontal pipe 301, the first vertical pipe 302 and the second horizontal pipe 303 connected in sequence, the first horizontal pipe 301 is communicated with the initial rainwater drainage well 60, the second horizontal pipe 303 is communicated with the enclosed landscape water body 40, and the two ends of the first vertical pipe 302 are connected with the first horizontal pipe 301 and the second horizontal pipe 303 respectively, realizing the height difference of the first horizontal pipe 301 and the second horizontal pipe 303 in the vertical direction, realizing the efficient transmission of rainwater from the initial rainwater drainage well 60 to the enclosed landscape water body 40, reducing the residence time of rainwater in the first pipeline 30, ensuring that the rainwater can flow smoothly along the preset path, realizing the smooth supplement of rainwater to the enclosed landscape water body 40, and helping to maintain the normal water level of the enclosed landscape water body 40.
[0031] As Figure 1 , Figure 2As shown, in the present embodiment, the second channel 70 includes a second vertical pipe 701, a third horizontal pipe 702, an inclined pipe 703 and a fourth horizontal pipe 704 connected in sequence, the second vertical pipe 701 is communicated with the initial rain runoff well 60, the fourth horizontal pipe 704 is communicated with the flood drainage ditch, which ensures that the initial rain water accumulated in the initial rain runoff well 60 can be quickly and efficiently discharged through the second channel 70, avoids the long-time retention of the initial rain water in the well, reduces the accumulation and deposition of pollutants, and helps to keep the initial rain runoff well 60 clean and efficient operation. In addition, the second channel 70 forms a smooth rainwater flow path through the connection of the third horizontal pipe 702, the inclined pipe 703 and the fourth horizontal pipe 704, which not only ensures that the rainwater can flow smoothly in the preset direction, but also realizes the natural acceleration and smooth discharge of the rainwater through the setting of the inclined pipe 703, reducing the risk of pipe blockage and water accumulation.
[0032] As shown in Figure 1 , Figure 2 In the present embodiment, the connection position of the first pipe 30 with the initial rain runoff well 60 is higher than the connection position of the second channel 70 with the initial rain runoff well 60, so that the initial rain entering the initial rain runoff well 60 will first enter the second pipe, and then enter the flood drainage ditch for discharge, and then the relatively clean rainwater will enter the closed landscape water body 40 through the first channel, optimizing the discharge sequence of the rainwater and ensuring that the pollutants in the initial rain are preferentially treated.
[0033] As shown in Figure 1 , Figure 2 In the present embodiment, a rainwater interception ditch 80 is arranged between the first turf 10 and the footpath 20, which can effectively intercept the rainwater flowing from the first turf 10 to the footpath 20, especially the initial rainwater containing more pollutants, which helps to prevent the pollutants from flowing directly into the footpath 20 or other areas with rainwater, causing pollution spread. In addition, the side of the initial rain runoff well 60 away from the closed landscape water body 40 is connected with the rainwater interception ditch 80 through the third pipe 90, so that the initial rain will be guided to the rainwater interception ditch 80 and flow into the initial rain runoff well 60 through the third pipe 90, so that the initial rain can be discharged to the flood drainage ditch through the second channel 70, which helps to protect the water quality of the closed landscape water body 40 and prevent pollution caused by pollutants in the initial rain. In addition, the third pipe 90 is horizontally arranged, of course, the third pipe 90 can also be designed to be inclined downward, and in actual design, the placement direction of the third pipe 90 can be designed according to actual needs.
[0034] As shown in Figure 1 , Figure 2As shown, in the present embodiment, the connection position of the third pipeline 90 with the initial rain runoff well 60 is higher than the connection position of the first pipeline 30 with the initial rain runoff well 60, so that the rainwater collected in the rainwater interception ditch 80 can be quickly transferred to the initial rain runoff well 60. Since the connection position of the first pipeline 30 with the initial rain runoff well 60 is higher than the connection position of the second channel 70 with the initial rain runoff well 60, that is, the connection position of the third pipeline 90 with the initial rain runoff well 60 is higher than the connection position of the second channel 70 with the initial rain runoff well 60, so that the rainwater entering the initial rain runoff well 60 through the rainwater interception ditch 80 can enter the flood drainage ditch through the second pipeline.
[0035] Embodiment two
[0036] As Figure 3 shown, when the topographic conditions are not convenient for building the initial rain runoff well 60 in embodiment one, the rainwater interception area can be designed to include the lake-side infiltration belt 100, the lake-side infiltration belt 100 is in communication with the closed landscape water body 40 through the first pipeline 30, the lake-side infiltration belt 100 is laid along the lake shore edge of the closed landscape water body 40, and the main materials of the lake-side infiltration belt 100 are divided into cobblestone, coarse (quartz) sand and gravel from top to bottom, wherein the particle size of the cobblestone is 20mm-50mm, the laying thickness is about 100mm; the particle size of the coarse sand is 1mm-4mm, the laying thickness is 600mm-800mm; the particle size of the gravel is 20mm-40mm, the laying thickness is 150mm-200mm. In actual design, the laying materials and thickness of each layer of the lake-side infiltration belt 100 can be designed according to actual needs.
[0037] In the present embodiment, the wetland plant layer 110 is arranged on the lake-side infiltration belt 100, and the plant species of the wetland plant layer 110 can be designed as canna, cattail, spider orchid, reed, paper reed and the like. In actual design, the arrangement can be matched according to the needs of landscaping and viewing.
[0038] When it rains, the initial rainwater can intercept and filter scattered pollutants through the lake-side infiltration belt 100 and the wetland plant layer 110, prevent them from directly entering the closed landscape water body 40, reduce the influence of rainfall on the water transparency of the closed landscape water body 40, thereby reducing the pollutants carried in the rainwater runoff into the closed landscape water body 40, thereby reducing the pollution load of the closed landscape water body 40, maintaining the self-purification ability of underwater vegetation, and inhibiting the growth of algae. In addition, the plane where the first turf 10 is located is parallel to the plane where the footpath 20 is located. Of course, the plane where the first turf 10 is located can also be designed to be inclined to the plane where the footpath 20 is located. In actual design, the relationship between the plane where the first turf 10 is located and the plane where the footpath 20 is located can be designed according to actual needs.
[0039] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the utility model.
