[0027] In addition, in order to better illustrate the present application, a large number of specific details are given in the specific embodiments below. Those skilled in the art should understand that the present application can also be implemented without certain specific details. In some examples, methods, means, elements and circuits well known to those skilled in the art are not described in detail, in order to highlight the main idea of the present application.

[0028] The present application proposes a rainwater inlet system for a residential area, which is suitable for being buried in the ground, such as Figures 1 to 4As shown, it includes: a well body 100, a grate 121, a sewage intercepting member 122, a filter device 210 and a protective layer; openings are provided at the upper and lower ends of the well body 100, the grate 121 and the sewage intercepting member 122 are both arranged at the opening at the top of the well body 100, and the sewage intercepting member 122 is located at the bottom of the grate 121, the filter device 210 is arranged at the bottom of the well body 100, and a water outlet pipe 300 is provided on the side wall of the well body 100, and the water outlet pipe 300 is connected to the interior of the cavity of the well body 100; a mounting base 110 is provided around the bottom of the well body 100, and the well body 100 is fixed on the protective layer through the mounting base 110.

[0029] It should be noted here that the grate 121 can prevent large debris from entering the well body 100, avoid the accumulation of debris in the well body 100 and cause drainage blockage, and ensure the normal inflow of rainwater; the sewage interception member 122 is suitable for secondary filtration of rainwater entering the well body 100, reducing the amount of impurities entering the well body 100 and reducing the burden on the subsequent filtering device 210; the design of the well body 100 with openings at both ends provides more ways for rainwater to enter the well body 100. During rainfall, the top opening can receive rainwater that falls directly, while the bottom opening can receive rainwater that falls directly. The opening in the bottom can collect rainwater that penetrates through the ground. The filtering device 210 is suitable for deep filtering of rainwater entering the well body 100. One end of the outlet pipe 300 is connected to the well body 100, and the other end of the outlet pipe 300 is connected to the drainage channel. The outlet pipe 300 discharges the rainwater in the well body 100 into the municipal pipeline. The installation base 110 is suitable for fixing the well body 100 on the protective layer, ensuring the firmness of the well body 100 during use, avoiding the displacement of the well body 100 due to factors such as water flow impact, thereby ensuring the normal drainage function of the rainwater outlet system.

[0030] Compared with the prior art in which the filter device 210 is buried in the side wall of the well body 100, by setting the filter device 210 at the bottom of the well body 100, when the filtering effect of the filter device 210 decreases and needs to be replaced, the staff only needs to open the grate 121 and enter the bottom of the well body 100 through the wellhead to directly replace the filter device 210 without digging up the rainwater outlet. The operation is relatively simple and convenient, which greatly saves manpower, material and time costs and improves maintenance efficiency.

[0031] In one possible implementation, the filter device 210 is a water filter material wrapped with a corrosion-resistant mesh material.

[0032] Preferably, the filter device 210 is a ceramsite water filter bag wrapped with a fiberglass mesh.

[0033] Furthermore, the sewage intercepting member 122 is a water filter bag or a sewage intercepting basket.

[0034] In a possible implementation manner, the fixed support 120 is arranged on the well body 100; the fixed support 120 is arranged at the opening at the top of the well body 100, and the fixed support 120 is provided with a groove, and the edges of the grate 121 and the edges of the intercepting piece 122 are embedded in the groove.

[0035] It should be noted that, as shown in Figures 1 to 4 , the bottom of the fixed support 120 is fixedly arranged at the opening at the top of the well body 100, and the fixed support 120 is suitable for providing stable mounting support for the grate 121 and the intercepting piece 122, so as to avoid displacement of the grate 121 and the intercepting piece 122 during use; the fixed support 120 is provided with a groove on one side away from the well body 100, the groove is matched with the outer contour of the grate 121 and the intercepting piece 122, the edges of the grate 121 and the edges of the intercepting piece 122 are embedded in the groove and are flush with the ground, and the embedded connection mode can not only facilitate installation and disassembly of the grate 121 and the intercepting piece 122, but also effectively prevent them from accidentally separating from the fixed support 120 during normal use.

[0036] In a possible implementation manner, as shown in Figure 1 , Figure 2 , the thickness of the mounting base 110 is greater than the thickness of the wall of the well body 100; and one side of the bottom of the filtering device 210 is embedded in the mounting base 110.

[0037] It should be noted that the thicker mounting base 110 can provide a wider and more stable support surface for the well body 100; when the well body 100 is subjected to external force from above, the thicker mounting base 110 can effectively uniformly disperse the pressure to the ground, prolonging the service life of the well body 100, and at the same time, the mounting base 110 provides a stable mounting position for the filtering device 210, and the effective fixation of the filtering device 210 is achieved by embedding one end of the filtering device 210 in the mounting base 110, avoiding rainwater bypassing the filtering device 210 and directly entering from the bottom of the well body 100, so as to ensure that the rainwater entering the well body 100 passes through the filtering of the filtering device 210.

[0038] In a possible implementation manner, the weight 220 is further included; the weight 220 is arranged in the well body 100, and the weight 220 is placed on one side at the top of the filtering device 210.

[0039] It should be noted that the heavy part 220 is placed on one side of the top of the filter device 210. During the flow of rainwater, the filter device 210 may be subjected to upward buoyancy and cause displacement of the filter device 210. The heavy part 220 exerts downward pressure on the filter device 210 through its own weight; thereby avoiding the filter device 210 from floating or displacement, ensuring the stable fixation of the filter device 210 at the bottom of the well body 100.

[0040] Further, the heavy part 220 is a large particle size pebble wrapped by a glass fiber net.

[0041] In one possible implementation, as shown in Figure 3 , Figure 4 The protective layer includes, from top to bottom, a geotextile water filter layer 460, a drainage layer 410, a water-impermeable layer 420, a concrete protective layer 430, a waterproof layer 440, and a waterproof reinforced concrete slab 450. The drainage layer 410 is in communication with the cavity of the well body 100 through an opening at the bottom of the well body 100.

[0042] It should be noted that the protective layer is formed by sequentially stacking the geotextile water filter layer 460, the drainage layer 410, the water-impermeable layer 420, the concrete protective layer 430, the waterproof layer 440, and the waterproof reinforced concrete slab 450, thereby having the functions of drainage and waterproofing. Through the synergistic effect of each layer, the well body 100 and the entire rainwater inlet system are effectively protected from groundwater and excessive rainwater. Under different rainfall conditions, the normal operation of the rainwater inlet system can be ensured.

[0043] The drainage layer 410 is communicated with the cavity of the well body 100 through the opening at the bottom of the well body 100, and is suitable for collecting and guiding rainwater, and orderly conveying rainwater penetrated from the ground into the well body 100; the waterproof layer 420 is located below the drainage layer 410, and is suitable for preventing rainwater from continuing to penetrate downward from the drainage layer 410, and ensuring that the lower structure is not eroded by rainwater; the concrete protection layer 430 is located below the waterproof layer 420, and disperses the pressure from the ground when the ground is driven by vehicles or stepped by pedestrians, so as to avoid damage of the waterproof layer 440 below due to excessive pressure; the waterproof layer 440 is located below the concrete protection layer 430, and is suitable for preventing plant root systems from penetrating the waterproof layer 440, thereby avoiding rainwater from penetrating into the underground structure, and reducing problems such as ground subsidence or damage of the rainwater inlet caused by waterproof failure; the waterproof reinforced concrete slab 450 serves as the bottom layer and provides a solid foundation support for the rainwater inlet system of the application, and can bear the weight from the upper protection layer and the well body 100, and various loads from the ground, thereby ensuring the safety and stability of the underground structure; the geotextile water filtering layer 460 is suitable for filtering rainwater penetrated into the drainage layer 410, and in the process of rainwater penetration, the soil 500 is driven by rainwater and enters the drainage layer 410, and the geotextile filtering layer 460 can effectively prevent the soil 500 from entering the drainage layer 410 along with the rainwater, thereby avoiding the phenomenon of blockage of the drainage layer 410.

[0044] Further, the drainage layer 410 is paved with gravel, and the thickness of the drainage layer 410 is 150 mm.

[0045] Further, the waterproof layer 420 is paved and tamped with waterproof soil, the tamping coefficient of the waterproof layer 420 is 0.94, and the thickness of the waterproof layer 420 is 500 mm.

[0046] Further, the thickness of the concrete protection layer 430 is 70 mm.

[0047] In a possible implementation manner, a preset distance h is provided between the water outlet pipe 300 and the ground, the preset distance h is designed so that rainwater in the well body 100 is not directly discharged into the municipal pipeline by the water outlet pipe 300, the rainwater first accumulates in the soil 500 to a sufficient amount and then enters the drainage layer 410, the rainwater in the drainage layer 410 is discharged into the municipal pipeline by the water outlet pipe 300 after being filtered by the filtering device 210, the height of the water outlet pipe 300 is designed to ensure that the rainwater in the soil 500 is not inversely penetrated to the ground, and at the same time, to ensure that the water storage in the soil 500 can be absorbed and utilized by plants, thereby reducing the irrigation frequency of greening.

[0048] Preferably, the preset distance h is 550 cm.

[0049] As Figure 3 shown, at the beginning of the rainfall, most of the rainwater falls on the ground and then seeps into the soil 500, the rainwater seeps from the soil 500 to the drainage layer 410, a part of the rainwater directly falls into the well body 100 and then enters the drainage layer 410 through the filter device 210, as Figure 4 shown, with the increase of rainfall, when the amount of rainwater is enough, the rainwater entering the drainage layer 410 seeps into the well body 100 through the filter device 210 at the bottom of the well body 100, when the rainwater seeping into the well body 100 reaches the horizontal plane where the water outlet pipe 300 is located, the filtered rainwater is discharged to the municipal pipeline through the water outlet pipe 300; as Figure 5 shown, during heavy rain, a large amount of rain falls in a short time, and the rainwater cannot seep into the soil 500 on the ground to form surface water, the surface water can flow directly into the well body 100 through the grate 121, and the rainwater in the well body 100 enters the drainage layer 410 through the filter device 210, as Figure 6 shown, when the rainwater in the well body 100 and the drainage layer 410 reaches the horizontal plane where the water outlet pipe 300 is located, it is discharged to the municipal pipeline through the water outlet pipe 300.

[0050] Further, a blind pipe is arranged in the drainage layer 410, the drainage end of the blind pipe is in communication with the municipal pipeline, and the blind pipe can quickly collect and transport the rainwater in the drainage layer 410; in the drainage layer 410, the rainwater may be unevenly distributed due to the seepage speed, seepage direction and other factors, the blind pipe can concentrate the rainwater around it, and compared with natural seepage drainage, the blind pipe can greatly improve the drainage efficiency.
