Detailed Description

The technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings in combination with embodiments.

According to an aspect of the present utility model, there is provided a gully structure including: the cavity 500 is arranged below a road with a gradient, and the cavity 500 is limited by the side wall and the bottom wall and is provided with a water outlet 400; a rain water inlet installed at the top of the cavity 500 and allowing rain water to enter the draining device 100 of the cavity 500; the filtering part 301 is installed at the bottom of the cavity 500 to divide the cavity 500 into a drainage cavity 502 communicating with the drainage port 400 and a storage cavity 501, wherein the filtering part 301 is located below the draining device 100, and at least a part of the draining device 100 is located above the storage cavity 501 and near the higher side of the road.

According to the technical scheme of the utility model, rainwater flows into the storage cavity 501 through the draining device, can be precipitated and filtered in the storage cavity 501, flows into the drainage cavity 502 through the filtering part 301 and finally is discharged into the public drainage pipeline through the drainage port 400, wherein pollutants such as sediment, tire abrasion and the like are intercepted in the storage cavity 501 by the filtering part 301, and the rainwater flows into the drainage port 400 after being filtered, so that the pollutants discharged into a water body along with the rainwater are effectively reduced.

In this technical solution, the upper surface of the draining device 100 may be flush with or slightly lower than the upper surface of the road around the draining device 100, so that rainwater can smoothly flow into the cavity 500 through the draining device 100, and rainwater is prevented from accumulating around the draining device 100 due to the fact that the draining device 100 protrudes out of the road. The cavity 500 is divided into a drainage cavity and a storage cavity 501 by the filtering portion 301, and in actual use, the road on two sides of the draining device 100 has a height difference due to the gradient of the road surface, so that water flow is guided to flow from the higher side of the road to the draining device 100 and then flow into the storage cavity 501. For ease of illustration, referring to one of the cases shown in fig. 2, the right side of the road may have a high height, and rainwater may flow from right to left, from the right side of the drainage device 100 into the storage chamber 501.

In general, the rainwater on the road flows into the storage chamber 501 from the portion above the storage chamber 501 for sedimentation and filtration, so that the pollutants with larger density such as sediment, sand and stone are sedimented to the bottom of the chamber, and the pollutants with smaller density such as tire wear and grease can be stopped by the filtration part 301 although they are not sedimented, and the sedimented and filtered clean rainwater flows into and is discharged into the public drainage pipeline through the drainage port 400.

In addition, the draining device 100 may further have a portion above the draining cavity 502, where the draining device 100 may enable rainwater falling from the sky and rainwater cleaner in the late period of rainfall to directly enter the draining cavity 502 for direct drainage, and since there is no more flushable matter in the rainwater, the rainwater is cleaner and does not need to be filtered, so that when the precipitation is too large, the rainwater can directly enter the draining cavity 502 through the draining device and be drained, thereby improving drainage capability.

The filtering portion 301 may take various forms, for example, the filtering portion 301 may take a filter screen, a water permeable wall, or a combination of a filter screen and a water permeable wall, which is not limited herein, as long as it can stop contaminants and filter rainwater. The filtering part 301 may have a height lower than the cavity 500 so that, when the amount of water is excessively large, rainwater accumulated in the storage chamber 501 can spread through the filtering part 301 into the drainage chamber 502 to avoid affecting the drainage effect. Alternatively, when the filtering part 301 takes the form of a screen or the like, since the filtering time is faster, it may have the same height as the cavity 500, and the drainage effect is not affected.

The side walls and the bottom wall of the cavity 500 may be in the form of a concrete prefabricated wall, and the drain outlet 400 may be formed at a proper position, for example, may be formed at the bottom wall or the side wall of the drain cavity 502, so that filtered water smoothly flows into the public drain pipeline.

By the technical scheme, rainwater flows into the storage cavity 501 along the road, flows into the drainage cavity 502 after precipitation and filtration and flows into the public drainage pipeline through the drainage outlet 400, so that pollutants such as sediment, tire wear or grease are prevented from being discharged into the water body along with the rainwater.

In order to enable water flowing into the drainage cavity 502 to flow into the drainage port 400 in time, thereby avoiding unnecessary accumulation of rainwater in the drainage cavity 502, according to a preferred embodiment, as shown in fig. 2, the drainage port 400 is provided at a side wall of the drainage cavity 502, and the drainage port 400 is provided at a lower level than the filtering part 301.

In this technical scheme, the water outlet 400 is formed in the side wall of the water outlet cavity 502, and the height of the water outlet 400 can be lower than that of the filtering portion 301, so that excessive rainwater is prevented from accumulating in the water outlet cavity 503. Also, the bottom of the drain opening 400 may be a distance above the bottom of the drain cavity 502 to allow the rain water to further settle and filter within the cavity from the bottom of the drain opening 400 to the bottom of the drain cavity 502.

The drain device 100 may take a suitable form to facilitate the flow of rainwater along a path into the storage chamber 501. According to a preferred embodiment, the drain device 100 includes a base 101 in the form of a frame, and a plurality of adjacent water grates 110 mounted to the base 101, wherein at least one of the water grates 110 is located above the storage chamber 501.

In this embodiment, the base 101 may be mounted to the rainwater inlet, and the base 101 may be provided with a plurality of openings for mounting the plurality of water grates 110 thereto. The water grating 110 may take the form of, for example, a grating to facilitate the passage of water, and in order to allow the rainwater in the road to flow preferentially into the storage chamber 501 to avoid the rainwater from flowing into the drainage chamber 502 due to too little water leakage capacity, at least one water grating 110 may be located above the storage chamber 501, although more may be arranged to provide sufficient water leakage capacity to the portion of the drainage device 100 above the storage chamber 501.

Through this technical scheme, at least one water grate 110 is installed in the storage chamber 501 top, makes the waterlogging caused by excessive rainfall device 100 part of storage chamber 501 top have sufficient ability of leaking to make the rainwater flow into smoothly in storage chamber 501 along the road through the water grate 110 of storage chamber 501 top.

Since the rainwater falling directly from the sky and the rainwater cleaner in the late period of the rainfall have no more flushable substances and do not carry a great amount of pollutants such as silt, tire abrasion, grease, broken stone, leaves and the like, the rainwater is cleaner and does not need to be deposited and filtered, and can be directly discharged, according to a preferred embodiment, as shown in fig. 1 and 2, at least one water grate 110 is positioned above the drainage cavity 502.

The rainwater with more pollutants on the road can flow from the diversion of the road slope and flow from the higher side into the storage cavity 501 through the first water grate 110 so as to precipitate and filter the rainwater with more impurities. Whereas cleaner rain water falling directly from the sky and late in the rainfall can pass through the second grate 112 directly into the drainage cavity 502.
