Description

Technical Field

[0001] This utility model relates to the fields of sponge city and urban drainage technology, specifically to an integrated interception and overflow rainwater grate device. Background Technology

[0002] Traditional storm drains in urban drainage systems have the following main problems:

[0003] Lack of interception effect: Traditional rainwater inlets are mostly designed for single drainage function, and have no interception capacity for sewage and initial rainwater. This results in a large amount of untreated sewage and initial rainwater entering the municipal pipe network directly, putting huge pressure on municipal drainage and wasting water resources.

[0004] Limited storage capacity: The lack of effective storage space cannot meet the temporary storage needs of rainwater. When the rainfall is heavy, it can easily lead to the overload operation of the rainwater pipe network, increasing the risk of urban flooding.

[0005] Complex structure: Traditional rainwater inlets only have a drainage function. In order to retain the design storage capacity, it is necessary to lay grooves around the drainage outlet, resulting in high manufacturing costs, low aesthetics, and difficulty in installation and maintenance.

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.

[0031] 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.

[0032] like Figure 1-4 As shown, this utility model provides an integrated overflow and interception rainwater grate device, including a base 1, a drain outlet cover 2 covering the upper end of the base 1, and a water interception trough cover 3. A drain outlet 102 extending vertically is provided in the middle of the base 1, and the drain outlet cover 2 covers the upper end of the drain outlet 102. At the outer edge of the drain outlet 102, a water interception trough 103 for interception is regularly arranged on the base 1, and the water interception trough cover 3 covers the upper end of the water interception trough 103.

[0033] Furthermore, such as Figure 2 As shown, at the upper end of the drain outlet 102, a cover plate support step 1021 is regularly provided to facilitate the support of the drain outlet cover plate 2. The drain outlet cover plate 2 is laid on the upper end of the drain outlet 102 through the cover plate support step 1021.

[0034] Furthermore, in one embodiment, the upper end of the intercepting trough 103 is also regularly provided with supporting steps to facilitate support of the intercepting trough cover plate 3. Alternatively, as... Figure 2 As shown, by regularly arranged in the intercepting trough 103, a number of support plates 1031 are provided to support the intercepting trough cover plate 3 on the upper end of the intercepting trough 103.

[0035] Furthermore, such as Figure 3 As shown, the base 1, located at the front end of the water interception channel 103, has regularly arranged drainage holes 104 to facilitate rainwater outflow. Figure 2As shown, the drain cover plate 2 is regularly provided with several drain slits / drain holes 201 to facilitate the flow of rainwater, as well as a decorative area 202 for patterned decoration. The drain slits 201 are regularly arranged to avoid the decorative area 202.

[0036] Furthermore, such as Figure 2 As shown, the water interception trough cover plate 3 is regularly provided with several water interception slits / holes 301 to facilitate the flow of rainwater.

[0037] Furthermore, the water interception trough 103 is a U-shaped water interception trough, which is set at the left and right ends and the rear end of the base 1.

[0038] like Figure 5 The diagram shows an example of the paving installation of this device. A high curbstone 5 is installed between road 4 and green belt 6, and the base 1 of this invention is paved in road 4. Simultaneously, a drainage hole 104 is provided on the high curbstone 5 at the front end of the intercepting trough, facilitating the passage of rainwater from the intercepting trough 103. This allows rainwater to flow easily into the green belt 6 through the opening on the high curbstone 5. Correspondingly, to purify the rainwater, several prefabricated energy-dissipating and sewage-intercepting devices 7 and pebbles 8 are regularly arranged in the green belt 6 near the high curbstone 5. After passing through the high curbstone 5, the rainwater in the intercepting trough 103 is filtered and purified by the prefabricated energy-dissipating and sewage-intercepting devices 7 and pebbles 8 before extending into the ground from the green belt 6 to replenish groundwater.

[0039] Furthermore, the drainage outlet 102 on the base 1 is connected to the rainwater well, and the intercepting channel 103 on the base 1 extends forward, passing through the high side stone 5. During the initial stages of rainfall or when the rainfall is light, rainwater is intercepted by the intercepting channel 103 at the edge of the device and discharged from the drainage hole 104 at its front end. After being filtered by the prefabricated energy-dissipating and pollution-intercepting device 7 and the pebbles 8, it is then introduced into the green area for infiltration and purification. When the rainfall is heavy, excess rainwater is quickly discharged into the urban pipe network through several drainage slots 201 on the drainage outlet cover plate 2 and the drainage outlet 102 channel on the base 1. Thus, this device achieves the functions of interception and overflow, preventing flooding and controlling pollution, while also providing ecological benefits and drainage safety.

[0040] like Figure 1 and Figure 4 As shown, in order to facilitate the paving work of this device, the outer side of the base 1 protrudes outward to form an installation step 101. The installation step 101 is then covered with cement mortar, so that the device can be paved in the road.

[0041] Furthermore, to enhance the stability and firmness of the base 1, it can be fixedly connected to the concrete subbase under the road by using an adapter plate and expansion bolts, thereby stably fixing the base of this device onto the concrete subbase under the road. Subsequently, the installation steps at the edge of the base are covered with cement mortar, thus stably paving the base in the road.

[0042] Furthermore, such as Figure 1 and Figure 4 As shown, in order to facilitate the introduction of the water interception trough 103 on the base 1 into the green belt / green space, the water interception trough 103 extends forward from the front end of the base 1 to form an extension section of the water interception trough.

[0043] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
