Description

Technical Field

[0001] The utility model relates to the technical field of urban drainage, and particularly relates to a disconnection drainage structure. Background Technique

[0002] Sponge City is an emerging urban design concept. It draws on the water absorption and release characteristics of natural sponges and aims to build an urban environment that can efficiently manage rainwater resources. In such a city, rainwater is not only a burden on the urban drainage system but also a precious resource. Specifically, Sponge City can absorb, store, infiltrate, and purify rainwater when it rains, and "release" and utilize the stored water when needed.

[0003] In the construction of Sponge City, building drainage and road drainage play crucial roles. Building drainage is responsible for collecting the water volume from parts such as roofs, balconies, and air-conditioning condensate drain pipes, and guiding it orderly to the ground or the municipal drainage system through drainage pipes. Rainwater inlets are usually set in green spaces, sidewalks, and non-motor vehicle passage areas, and have functions of rainwater collection, pollution interception, infiltration, and discharge. At present, the building drainage structure and rainwater inlets are often independent in design and implementation, and the outlet of the building drain pipe is usually exposed above the ground. When draining, it will not only cause rainwater to splash, but also the drainage may erode the green space around the discharge port, resulting in poor growth or death of plants after long-term scouring. Content of the Utility Model

[0004] The main purpose of the utility model is to propose a disconnection drainage structure, aiming to solve the problems that the building drainage outlet is exposed above the ground, which is easy to cause drainage splashing and ground scouring.

[0005] To achieve the above purpose, the disconnection drainage structure proposed by the utility model includes a drain pipe, a disconnector, and a reservoir. The drain pipe is installed on the building wall. The drain pipe includes an upper drain pipe and a lower drain pipe. The disconnector includes a water storage chamber and an overflow pipe. The water storage chamber is arranged between the upper drain pipe and the lower drain pipe to connect the upper drain pipe and the lower drain pipe. The flow-through area of the water storage chamber is larger than that of the drain pipe. An overflow port is opened at the top of the water storage chamber, and the overflow pipe is inserted into the overflow port. The reservoir is arranged below the ground, and the lower drain pipe and the overflow pipe are both connected to the reservoir.

[0006] In one embodiment, the disconnecter further includes a housing, the water storage bin and the overflow pipe are both arranged inside the housing, a first insertion opening is formed in the top wall of the housing, a second insertion opening is formed in the bottom wall of the housing, the upper drain pipe is inserted into the first insertion opening to communicate with the water storage bin, and the lower drain pipe is inserted into the second insertion opening to communicate with the water storage bin. An outlet is formed in the side wall of the housing, the outlet is located at the bottom of the housing, and the water flowing out from the overflow pipe flows into the reservoir through the outlet.

[0007] In one embodiment, the reservoir is arranged at an interval from the disconnecter, a green space is arranged between the reservoir and the disconnecter, and the drain outlet of the lower drain pipe is arranged in the green space.

[0008] In one embodiment, a sewage interception basket is arranged in the reservoir, and the water outlet end of the lower drain pipe is inserted into the sewage interception basket for drainage.

[0009] In one embodiment, permeation holes are formed in the side wall of the reservoir, and the water in the reservoir permeates into the soil layer through the permeation holes.

[0010] In one embodiment, a plurality of permeation pipes are communicated with the bottom of the reservoir, permeation holes are formed in the side walls of the permeation pipes, and the water in the permeation pipes permeates into the ground through the permeation holes.

[0011] In one embodiment, a manhole cover is arranged on the top surface of the reservoir.

[0012] In one embodiment, a water outlet pipe is connected to one side of the reservoir.

[0013] In one embodiment, the disconnect drainage structure further includes a rainwater well arranged at an interval from the reservoir, and the water outlet pipe is communicated with the rainwater well.

[0014] In one embodiment, the water storage bin includes a straight surface section and a conical surface section arranged at the lower end of the straight surface section, a top wall opening is formed in the top wall of the straight surface section, a bottom wall opening is formed at the lowest point of the conical surface section, the upper drain pipe is inserted into the top wall opening to communicate with the water storage bin, and the lower drain pipe is inserted into the bottom wall opening to communicate with the water storage bin.

[0015] The disconnection and drainage structure of the utility model breaks the drainage pipe and sets a water storage bin at the breaking position to buffer the water flow. The flow-through area of the water storage bin is larger than that of the drainage pipe. When the water flow flows from the drainage pipe with a smaller cross-section into the water storage bin with a larger cross-section, its flow velocity will decrease, and the kinetic energy and potential energy will be weakened, thereby realizing the energy dissipation of the water flow and avoiding the scouring and erosion of the ground by the water flow. When the drainage volume is small, the water in the upper drainage pipe flows through the water storage bin and the lower drainage pipe in sequence, and then drains into the water storage pool; during the peak period of heavy rain when the drainage volume is large, the water volume in the upper drainage pipe will fill the water storage bin. Part of the water in the water storage bin is discharged through the lower drainage pipe, and the other part overflows through the overflow pipe. At the same time, the lower drainage pipe and the overflow pipe guide the water in the water storage bin to the water storage pool below the ground, avoiding the problem of water splashing during drainage.

[0026] The present utility model proposes a disconnection drainage structure.

[0027] Please refer to Figures 1 to 3 , an embodiment of this disconnection drainage structure includes a drain pipe 1, a disconnector 2, and a reservoir 3. The drain pipe 1 is installed on the building wall 7. The drain pipe 1 includes an upper drain pipe 111 and a lower drain pipe 122. The disconnector 2 includes a water storage chamber 22 and an overflow pipe 23. The water storage chamber 22 is arranged between the upper drain pipe 111 and the lower drain pipe 122 to connect the upper drain pipe 111 and the lower drain pipe 122. The flow-through area of the water storage chamber 22 is larger than the flow-through area of the drain pipe 1. An overflow port is opened at the top of the water storage chamber 22, and the overflow pipe 23 is inserted into the overflow port. The reservoir 3 is arranged below the ground 9, and both the lower drain pipe 12 and the overflow pipe 23 are communicated with the reservoir 3.

[0028] The drain pipe 1 in this disconnection drainage structure can be installed on the outdoor wall or the indoor wall. When the drain pipe 1 is installed on the outdoor wall, it is for building external drainage, such as Figure 1As shown; when the drain pipe 1 is installed on the indoor wall, it is for building drainage, such as Figure 2 As shown. Traditional building drain pipes 1 often run through to the bottom, while in this technical solution, the drain pipe 1 is interrupted into an upper drain pipe 11 and a lower drain pipe 12. The upper drain pipe 11 is connected to the roof drain pipe 1 and / or the air conditioner drain pipe 1 to collect the water volume from parts such as the roof and the air conditioner drain pipe 1. The lower drain pipe 12 is used to collect the water volume from the upper drain pipe 11. A water storage bin 22 is arranged between the upper drain pipe 11 and the lower drain pipe 12 to connect the upper drain pipe 11 and the lower drain pipe 12. Specifically, the water storage bin 22 is in a funnel shape, that is, the water storage bin 22 includes a straight surface section and a conical surface section arranged at the lower end of the straight surface section. The top wall of the straight surface section is provided with a top wall opening, and the lowest point of the conical surface section is provided with a bottom wall opening. The upper drain pipe 11 is inserted into the top wall opening to communicate with the water storage bin 22, and the lower drain pipe 12 is inserted into the bottom wall opening to communicate with the water storage bin 22. The funnel-shaped setting of the water storage bin 22 can make the water flow converge towards the center point, facilitating the centralized discharge of the water volume. At the same time, an overflow port is also provided on the top wall of the water storage bin 22. The overflow port is connected to an overflow pipe 23. The drainage ends of the overflow pipe 23 and the lower drain pipe 12 can be directly inserted into the water storage tank 3 for drainage, or the drainage ends of the overflow pipe 23 and the lower drain pipe 12 can be inserted below the ground 9 for drainage into the soil layer, and the water that cannot be absorbed by the soil layer then seeps into the water storage tank 3.

[0029] The disconnection drainage structure of the utility model interrupts the drain pipe 1 and sets a water storage bin 22 at the interruption position to buffer the water flow. The flow-through area of the water storage bin 22 is larger than that of the drain pipe 1. The water flow flows from the drain pipe 1 with a smaller cross-section into the water storage bin 22 with a larger cross-section, and its flow velocity will decrease, and the kinetic energy and potential energy will be weakened, thereby realizing the energy dissipation of the water flow and avoiding the scouring and erosion of the ground 9 by the water flow. When the drainage volume is small, the water in the upper drain pipe 11 flows through the water storage bin 22 and the lower drain pipe 12 in sequence, and then drains into the water storage tank 3; during the peak period of heavy rain when the drainage volume is large, the water volume in the upper drain pipe 11 will fill the water storage bin 22. Part of the water in the water storage bin 22 is discharged through the lower drain pipe 12, and the other part overflows through the overflow pipe 23. At the same time, the lower drain pipe 12 and the overflow pipe 23 guide the water in the water storage bin 22 to the water storage tank 3 below the ground 9, avoiding the problem of water splash during drainage.

[0030] In an embodiment of this disconnection drainage structure, the disconnector 2 further includes a housing 21. The water storage bin 22 and the overflow pipe 23 are both arranged inside the housing 21. A first insertion port is formed in the top wall of the housing 21, and a second insertion port is formed in the bottom wall of the housing 21. The upper drain pipe 11 is inserted into the first insertion port from top to bottom to communicate with the water storage bin 22, and the lower drain pipe 12 is inserted into the second insertion port from bottom to top to communicate with the water storage bin 22. The housing 21 is used to hide the water storage bin 22 and the overflow pipe 23, thereby ensuring the aesthetic appearance of the building facade. During installation, only the housing 21 needs to be fixed to the building wall 7, and then the upper drain pipe 11 is inserted into the first insertion port from top to bottom to communicate with the water storage bin 22, and the lower drain pipe 12 is inserted into the second insertion port from bottom to top to communicate with the water storage bin 22, then the installation of the water storage bin 22 and the overflow pipe 23 can be realized.

[0031] At this time, a water outlet is formed in the side wall of the housing 21. The water outlet is located at the bottom of the housing 21. The water flowing out of the overflow pipe 23 flows into the water storage tank 3 through the water outlet.

[0032] When the drainage volume is small, the water in the upper drain pipe 11 flows through the water storage bin 22 and the lower drain pipe 12 in sequence, and then drains to the water storage tank 3; when the drainage volume is large, the water volume in the upper drain pipe 11 will fill the water storage bin 22. A part of the water in the water storage bin 22 is discharged through the lower drain pipe 12, and the other part overflows into the chamber of the housing 21 through the overflow pipe 23, and then the water in the chamber of the housing 21 flows into the soil layer or the water storage tank 3 through the water outlet on the side wall of the housing 21.

[0033] In Figure 3 In the shown embodiment, the water storage tank 3 and the disconnector 2 are arranged at intervals. There is a green space 8 between the water storage tank 3 and the disconnector 2. The drain outlet of the lower drain pipe 12 is arranged in the green space 8, and the water volume that cannot be absorbed by the green space 8 flows into the water storage tank 3.

[0034] When there is a green space 8 at the building exterior wall, the water storage tank 3 and the disconnector 2 are separately arranged. At this time, the water storage tank 3 is preferably arranged in the green space 8. At this time, the drain outlet of the lower drain pipe 12 is arranged in the green space 8. At this time, the water discharged from the lower drain pipe 12 and the water seeping out from the disconnector 2 are both first absorbed by the green space 8, thereby realizing the resource utilization of building drainage.

[0035] In this disconnection drainage structure, a sewage interception basket 4 is arranged in the water storage tank 3, and the water outlet end of the lower drain pipe 12 is inserted into the sewage interception basket 4 for drainage.

[0036] It should be noted that the sewage interception basket 4 is arranged at the upper part of the reservoir 3, and the sewage interception basket 4 is provided with filter holes for filtering water flow. The water outlet end of the lower drain pipe 12 is inserted into the sewage interception basket 4, and the water discharged by the lower drain pipe 12 first passes through the sewage interception basket 4 for filtration and then flows into the reservoir 3 through the filter holes, so as to prevent large pieces of sediment carried in the water flow from depositing at the bottom of the reservoir 3.

[0037] The side wall of the reservoir 3 is provided with infiltration holes 32, and the water in the reservoir 3 infiltrates into the soil layer through the infiltration holes 32. In this embodiment, by providing the infiltration holes 32 on the side wall of the reservoir 3, the water volume in the reservoir 3 can infiltrate into the soil layer through the infiltration holes 32. On the one hand, it helps to supplement the groundwater resources, and on the other hand, it can reduce the load of the reservoir 3, thereby reducing the pressure on the drainage system.

[0038] Furthermore, a plurality of infiltration pipes 31 are connected to the bottom of the reservoir 3, and the side walls of the infiltration pipes 31 are provided with infiltration holes 32. The water in the infiltration pipes 31 infiltrates into the soil layer through the infiltration holes 32. The arrangement of the infiltration pipes 31 can increase the capacity of the reservoir 3 without making the volume of the reservoir 3 too large. The function of the infiltration holes 32 here is the same as that of the infiltration holes 32 described above, and will not be repeated here.

[0039] In addition, a manhole cover 5 is covered on the top surface of the reservoir 3 to prevent pedestrians or vehicles from accidentally falling in and reduce the entry of sundries into the reservoir 3.

[0040] In addition, a water outlet pipe 6 is connected to one side of the reservoir 3, and the water outlet pipe 6 is used to discharge the water in the reservoir 3 to the municipal drainage system.

[0041] For example, this disconnection drainage structure further includes a rainwater well (not marked) arranged at an interval from the reservoir 3, and the water outlet pipe 6 is communicated with the rainwater well. When the water storage volume in the reservoir 3 is small, the water in the reservoir 3 can infiltrate into the surrounding soil layer through the infiltration holes 32. When the water storage volume in the reservoir 3 is large, the water in the reservoir 3 can be discharged to the rainwater well through the water outlet pipe 6, which conforms to the design concept of the sponge city.

[0042] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
