Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building drainage and rainwater collection and utilization, in particular to a novel rainwater collection system for a residential ground and a rainwater garden. Background Art
[0002] In order to improve the quality and maintenance management of the community, the road surface of the community is generally hardened. Side strips are built on both sides of the road surface of the community to collect rainwater on the road surface. Grille covers are covered on the side strips to intercept large debris on the one hand and facilitate pedestrians to walk and prevent pedestrians from falling into the side strips on the other hand. Rain gardens are built on the side of the side strips to control the runoff pollution of rainwater on the road surface to meet the index control requirements of the sponge city construction of the community. At present, the conventional connection between the side strips and the rain garden is to build a collection trough at a certain interval in the side strip. The depth of the collection trough is slightly greater than the depth of the side strip. The collection trough is connected to the rain garden through a pipe to collect rainwater in the rain garden. The rain garden is an ecologically sustainable facility for flood control and rainwater purification and utilization. It is a naturally formed or artificially excavated shallow green space that is used to gather and absorb rainwater from the roof or the ground. Through the combined action of plants and sand, the rainwater gradually penetrates into the soil and is purified before being discharged, or the purified rainwater is used to replenish the community landscape water, road washing water, etc. The current drainage methods of border strips and rain gardens have the following problems: when it rains, dirt and dust on the road surface can easily enter the collection trough, and as rainwater flows into the rain garden, it will block the pipes on the one hand, and damage the plants and structures of the rain garden on the other hand. Utility Model Content
[0003] The purpose of the utility model is to provide a new rainwater collection system for the ground and rain garden of a residential area in order to solve the above-mentioned technical problems, so as to prevent mud and sand from entering the rain garden and causing damage to the plants and structures of the rain garden and blockage of the water inlet pipe of the rain garden.
[0004] In view of this, the utility model provides a novel rainwater collection system for the ground and rain garden of a residential area, including a road surface, side strips for collecting rainwater are built on both sides of the road surface, and a rain garden is arranged on the outer side of the side strip, characterized in that a certain slope is arranged at the bottom of the ditch of the side strip to facilitate the flow of rainwater, and siltation wells are built at a certain interval along the side strip, the depth of the siltation well is greater than the depth of the side strip, a vertically extending guide plate is arranged in the middle of the siltation well, the height of the guide plate is lower than the bottom of the ditch of the side strip, the guide plate divides the siltation well into two spaces, and a pipe connected to the rain garden is arranged on the upper part of the side wall of the chamber of the siltation well on the side of the low slope, the position of the pipe is lower than the guide, and the pipe is arranged away from the side of the guide plate, and a siltation inclined plate is arranged at the bottom of each space of the siltation well.
[0005] In the above scheme: a conical sand hopper is arranged at the bottom of each space of the sand hopper, and pull ropes are arranged on both sides of the bucket mouth of the conical sand hopper, and the upper end of the pull rope is sleeved on the grille cover plate of the side band. In this way, during maintenance, the sand hopper can be directly pulled out through the pull rope to clean the sand inside.
[0006] In the above scheme: the side walls of the guide plate and the side walls of the sedimentation well are provided with energy dissipation plates at intervals from top to bottom. It plays the role of dissipating the energy of the waterfall. Through the energy dissipation measures of the waterfall, the flow velocity can be slowed down and the sedimentation effect can be increased. The bottom surface of the energy dissipation plate is a curved surface, and the guide plate is provided with an energy dissipation plate at least at the top.
[0007] In the above scheme: the depth of the sedimentation well is 50-60 cm, which can meet the needs of rainwater collection and sedimentation effect.
[0008] In the above scheme: a sedimentation well is arranged every 15-20 meters in the side belt.
[0009] Beneficial effect: The utility model sets a sedimentation well, and rainwater flows from high to low along the slope of the side band into the chamber on the side of the sedimentation well away from the pipe. After sedimentation and energy dissipation in the chamber, the rainwater overflows from the top of the guide plate to the second chamber. After sedimentation continues in the second chamber, the rainwater flows into the rain garden through the upper pipe, thereby preventing mud and sand from entering the rain garden and causing damage to the plants and structure of the rain garden and clogging the water inlet pipe of the rain garden.

[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0013] Example 1
[0014] like Figure 1-2As shown, a new type of rainwater collection system for the ground and rain garden of the community includes a road surface 1. Side strips 2 for collecting rainwater are built on both sides of the road surface 1. Grille covers 10 are arranged on the side strips (the grille covers are not all drawn in the figure, and the covers 10 may not be arranged, but grille covers 10 are at least arranged above the siltation well), and a rainwater garden 3 is arranged on the outside of the side strip. A certain slope is arranged at the bottom of the ditch of the side strip 2 to facilitate the flow of rainwater. The slope of the slope should not be too large, as long as it is convenient for the flow of rainwater. Sedimentation wells 4 are built at certain intervals along the side strip. That is to say, by setting the slope of the side strip, rainwater only flows into the sedimentation well from the bottom side of the sedimentation well close to the side strip. Preferably, a sedimentation well is arranged at intervals of 100-200 meters in the side strip. The depth of the sedimentation well 4 is greater than the depth of the side strip 2. Preferably, the depth of the sedimentation well is 50-60 cm, the depth of the side strip is 8-10 cm, the width of the sedimentation well is 15-20 cm, and the length is 20-30 cm. The width of the sedimentation well is wider than the width of the side strip. A vertically extending guide plate 5 is arranged in the middle of the sedimentation well 4. The height of the guide plate 5 is lower than the bottom of the ditch of the side strip 2. The guide plate divides the sedimentation well into two spaces, that is, rainwater overflows from one space to another space through the guide plate. A pipe 6 is arranged on the upper part of the side wall of the chamber on the side of the low slope of the sedimentation well, which is connected to the rain garden 3. The position of the pipe 6 is lower than the guide 5. The pipe 6 is arranged away from the guide plate. A sedimentation inclined plate 11 is arranged at the bottom of each space of the sedimentation well 4. In order to facilitate maintenance, we set a conical sand hopper 7 at the bottom of each space in the sand hopper 4. The sand hopper 7 is surrounded by the bottom surface and the side surrounded by the sand sloping plate. Pull ropes 8 are set on both sides of the bucket mouth of the conical sand hopper 7. The upper end of the pull rope 8 is sleeved on the grille cover of the side belt. Energy dissipation plates 9 are set at intervals from top to bottom on the high side of the guide plate 5 and the side wall of the sand hopper 4. Figure 1 , the energy dissipation plate 9 is a short plate, which is arranged at intervals on the left and right. The bottom surface of the energy dissipation plate 9 is an arc surface, and the guide plate 5 is provided with an energy dissipation plate at least at the top. And an energy dissipation plate is provided in the middle of the side wall of the sedimentation well. If an energy dissipation plate is provided, the chamber on this side can only be provided with a fixed sedimentation inclined plate at the bottom (as shown in the figure, the sedimentation inclined plates are provided around the chamber, and the sedimentation inclined plates around the chamber are formed into a cone). The chamber on the other side can be provided with a movable sedimentation hopper 7.
[0015] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
