[0002] In urban drainage systems, traditional drainage ditches have a single function and cannot effectively regulate rainwater, easily leading to urban flooding. Furthermore, traditional drainage ditches lack ecological functions, failing to allow for natural rainwater infiltration and groundwater replenishment, which is inconsistent with the requirements of modern urban construction for sustainable water resource utilization and ecological environmental protection.

[0003] Moreover, traditional drainage ditches have poor landscaping effects, cannot be integrated with urban culture, and are difficult to improve the overall quality of the city. Utility Model Content

[0004] The technical problem solved by this utility model is to provide an integrated linear drainage ditch device for seepage and drainage.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An integrated linear drainage ditch device includes a storage and drainage component and an overflow component. The storage and drainage component is used to receive rainwater and perform preliminary interception, filtration, storage and infiltration of the rainwater. The overflow component is used to receive excess rainwater in the storage and drainage component, and after intercepting and filtering the excess rainwater, it is connected to the rainwater pipe network through a drainage pipe.

[0007] The storage and drainage assembly includes a storage and drainage outer frame. Along its axial direction, a U-shaped drainage ditch is regularly arranged on the upper part of the storage and drainage outer frame, which is connected from left to right. The upper end face of the ditch is covered by a first cover plate, which forms the upper end face of the storage and drainage outer frame. A first ecological porous fiber cotton for filtration is also arranged and installed in the storage and drainage U-shaped drainage ditch along its axial direction.

[0008] The overflow component includes an overflow outer frame. Along its axial direction, the upper end of the overflow outer frame is regularly provided with a U-shaped overflow drainage ditch that runs through the left and right sides. The upper end face of the overflow outer frame is covered by a second cover plate, which forms the upper end face of the overflow outer frame. At the left and right ends of the overflow U-shaped drainage ditch, one or more weirs for rainwater interception and filtration are also arranged and installed.

[0009] Furthermore, the dam includes a dam shell and a second ecological porous fiber cotton installed in the dam shell. The front, back, left and right sides of the dam shell are also regularly perforated with several drainage holes for rainwater to pass through.

[0010] Furthermore, the overflow outer frame is vertically provided with retaining wall slots at both ends of the overflow U-shaped drainage ditch to facilitate the insertion and installation of the retaining wall; the retaining wall is inserted and installed in the retaining wall slots; or, the retaining wall is directly fixed at both ends of the overflow U-shaped drainage ditch.

[0011] Furthermore, the overflow outer frame and the storage and drainage outer frame are regularly provided with several drainage holes on the front and rear end faces and / or bottom faces to facilitate rainwater infiltration into the soil.

[0012] Furthermore, the overflow outer frame and the storage and discharge outer frame are provided with regular protrusions and recesses on their left and right end faces, and are provided with protrusion structures and recesses that can be spliced ​​or locked together.

[0013] Furthermore, the upper part of the left end face of the storage and discharge outer frame and the overflow outer frame are regularly provided with outwardly protruding alignment protrusions, and the lower part of the left end face is regularly provided with inwardly recessed alignment recesses; the upper part of the right end face of the storage and discharge outer frame and the overflow outer frame, on the upper and lower parts of the left end face, the alignment protrusions and alignment recesses are regularly provided with alignment recesses and alignment protrusions that fit together.

[0035] To make the above-mentioned contents, objectives, and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0036] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figure 1-7 As shown, this utility model provides an integrated linear drainage ditch device, including a storage and drainage component 1 and an overflow component 2. The storage and drainage component 1 receives rainwater and performs initial interception, filtration, and infiltration. The overflow component 2 receives excess rainwater from the storage and drainage component 1, intercepts and filters it, and then discharges it into the municipal stormwater network through a drainage pipe. Thus, through the cooperation of the storage and drainage component 1 and the overflow component 2, the functions of rainwater interception, filtration, storage, and infiltration are achieved, effectively regulating rainwater and alleviating urban flooding.

[0038] like Figure 2 As shown, the storage and drainage assembly 1 includes a storage and drainage outer frame 11. The upper end of the storage and drainage outer frame 11 has a downwardly slotted groove along its axial / length direction, and a regularly arranged U-shaped drainage ditch 1101 running horizontally through it. The top surface of the ditch is covered by a cover plate 3. The cover plate 3 is installed in a cover plate mounting step 1102 at the upper end of the storage and drainage outer frame 11. The upper surface of the cover plate 3 is flush with the upper surface of the storage and drainage outer frame 11, thus integrating with the upper end of the storage and drainage outer frame 11 to form the upper surface of the storage and drainage outer frame 11.

[0039] Furthermore, a first ecological porous fiber cotton 12 is installed in the U-shaped drainage ditch 1101 of the outer frame 11, arranged along its axial / length direction. For example... Figure 5 and Figure 6 As shown, the first ecological porous fiber cotton 12 is regularly arranged along the length and width of the storage and drainage U-shaped drainage ditch and is laid flat in the storage and drainage U-shaped drainage ditch 1101.

[0040] like Figure 2 As shown, the overflow component 2 includes an overflow outer frame 21. The upper end of the overflow outer frame 21 has a downward groove along its axial / length direction, and a U-shaped overflow drainage ditch 2101 is regularly arranged running from left to right. Its upper end surface is also covered by a cover plate 3. The upper end surface of the cover plate 3 is also flush with the upper end surface of the overflow outer frame 21 and is integrated with it to form the upper end surface of the overflow outer frame 21.

[0041] Furthermore, the overflow component 2 has several weirs 22 for rainwater interception installed at both ends of its overflow U-shaped drainage ditch 2101.

[0042] Furthermore, such as Figure 4 As shown, the weir 22 includes a weir shell 221. The upper end of the weir shell 221 is slotted and has a fiber cotton slot 2211 for arranging and installing the second ecological porous fiber cotton 23. Several drainage holes 2212 for rainwater to pass through are also regularly arranged on the front and rear sides of the weir shell 221.

[0043] Furthermore, such as Figure 2 As shown, to facilitate the installation of the retaining weir 22 in the overflow U-shaped drainage ditch 2101, the overflow outer frame 21 is vertically equipped with retaining weir slots 2102 at both ends of the overflow U-shaped drainage ditch 2101 to facilitate the insertion and fixing of the retaining weir 22. The retaining weir slots 2102 enable a quick-release design for the retaining weir 22, allowing for periodic replacement of the retaining weir 22 and the second ecological porous fiber cotton 23 inside the retaining weir, ensuring the long-term stable operation of the device.

[0044] like Figure 3 and Figure 6 As shown, rainwater flows from the cover plate at the top of the storage and drainage component 1 into the storage and drainage U-shaped drainage ditch 1101. After being intercepted, filtered, and stored by the first ecological porous fiber cotton 12 in the storage and drainage U-shaped drainage ditch 1101, excess rainwater is discharged into the overflow component 2. The excess rainwater is intercepted by the weirs 22 at both ends of the overflow component 2, and after being filtered by the second ecological porous fiber cotton 23 in the weirs 22, it flows into the overflow U-shaped drainage ditch 2101. Finally, the rainwater filtered in the overflow U-shaped drainage ditch 2101 is connected to the rainwater pipe through the drain outlet 2103 and discharged into the municipal rainwater pipe network.

[0045] Furthermore, such as Figure 2 As shown, several infiltration holes 1105 are regularly arranged on the front and rear end faces and / or bottom faces of the storage and drainage outer frame 11 and the overflow outer frame 21 to facilitate rainwater infiltration. Rainwater flows into the soil through the infiltration holes 1105 and infiltrates downwards into the groundwater network, thereby replenishing the city's groundwater.

[0046] Furthermore, several drainage holes 1105 may be set according to specific circumstances and needs, or drainage holes may not be set, and the filtered rainwater may be directly discharged into the rainwater pipe network through the drainage outlet 2103 on the overflow U-shaped drainage ditch.

[0047] This invention integrates the functions of rainwater interception, filtration, storage and infiltration into one device through the integrated design of the overflow component 2 and the storage and discharge component 1, thereby effectively improving the rainwater treatment efficiency.

[0048] like Figure 1 and Figure 2 As shown, the storage and discharge assembly 1 and the overflow assembly 2 are modularly designed and are assembled together by splicing. To facilitate the splicing and assembly of the storage and discharge assembly 1 and the overflow assembly 2, the left and right end faces of the storage and discharge outer frame 11 and the overflow outer frame 21 are regularly designed with protrusions and recesses, and are provided with protrusions and recesses that can be spliced ​​or locked together on the left and right.

[0049] Furthermore, such as Figure 1 and Figure 2 As shown, in one embodiment, outwardly protruding alignment protrusions 1103 are regularly provided on the upper part of the left end face of the storage and discharge outer frame 11 and the overflow outer frame 21, and inwardly recessed alignment recesses 1104 are regularly provided on the lower part of the left end face. Correspondingly, on the right end face of the storage and discharge outer frame 11 and the overflow outer frame 21, the alignment protrusions 1103 and alignment recesses 1104 on the upper and lower parts of the left end face are respectively provided with mutually engaging outwardly recessed recesses and alignment protrusions, so that the storage and discharge assembly 1 and the overflow assembly 2 can be quickly assembled together.

[0050] The shape and position of the alignment protrusions and alignment recesses on the storage and discharge outer frame 11 and the overflow outer frame 21 are not limited, as long as they facilitate the alignment and splicing of the storage and discharge outer frame 11 and the overflow outer frame 21.

[0051] This utility model adopts a modular design for the storage and drainage component 1 and the overflow component 2, which has a simple and reliable structure. It can facilitate the production, transportation, flexible installation and subsequent maintenance of the storage and drainage component and the overflow component, thereby shortening the construction cycle. It can also flexibly splice and assemble the storage and drainage component and the overflow component according to drainage needs and site conditions to adapt to different drainage scenarios.

[0052] like Figure 7As shown, the upper surface of the cover plate 3 is patterned with regularly arranged patterns for aesthetic purposes, thereby enhancing the quality of the urban landscape and making the drainage ditch a window for showcasing urban culture. In one embodiment, as... Figure 7 As shown, a gear pattern is provided on the upper surface of the cover plate 3, forming a gear cover plate.

[0053] Furthermore, the gear cover is regularly provided with inlets to facilitate the flow of rainwater.

[0054] Furthermore, the lower end face of the cover plate 3 is regularly provided with reinforcing ribs for structural reinforcement.

[0055] Furthermore, the cover plate at the top of the storage and drainage component 1 is patterned and regularly arranged with inlets to facilitate rainwater inflow. The cover plate at the top of the overflow component 2 can also be patterned, but it does not have inlets for rainwater inflow.

[0056] like Figure 3 To reduce the weight and cost of the storage and discharge assembly 1 and the overflow assembly 2, a plurality of inwardly recessed weight-reducing grooves 1106 are regularly provided on the front and rear end faces and / or bottom faces of the storage and discharge outer frame 11 and the overflow outer frame 21, and a plurality of reinforcing ribs 1107 are provided or formed between the plurality of weight-reducing grooves 1106. The arrangement of the plurality of weight-reducing grooves 1106 reduces the weight and production cost of the storage and discharge outer frame 11 and the overflow outer frame 21. Simultaneously, the arrangement of the plurality of reinforcing ribs 1107 ensures the structural strength of the storage and discharge outer frame 11 and the overflow outer frame 21.

[0057] In practical use, such as Figure 1 As shown, one or more storage and drainage components 1 are spliced ​​at the left and right ends of the overflow component 2 to form a linear drainage ditch device. The main body of the drainage ditch is composed of the storage and drainage components 1, which receive rainwater and perform interception, filtration, storage, and infiltration of the rainwater. The overflow component 2 is used to receive excess rainwater from the storage and drainage components 1, and after intercepting and filtering the excess rainwater, it is discharged into the municipal rainwater pipe network through the drainage pipe.

[0058] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
