Abstract
Description
Technical Field
[0001] This utility model relates to the field of water environment management technology, specifically a concrete slope protection structure for water conservancy and river management. Background Technology
[0002] Against the backdrop of continuous urbanization, ecological problems are becoming increasingly prominent, and the situation of river water pollution is severe. Traditional river water treatment technologies have good short-term effects, but they are often only treating the symptoms and not the root cause for water self-purification and aquatic ecosystems. Not only are the treatment costs high, but there is also a greater possibility of secondary pollution to the environment.
[0003] According to a public notice of a planted concrete riverbank protection structure (Announcement No.: CN222513160U), the above application includes: a planted concrete slope protection surface, a water conduction system, and a purification module; the purification module of this utility model can intercept rainwater and spray water flowing down through the planted concrete slope protection surface, and after sedimentation in the collection tank, it is further filtered through a geotextile filter layer and a permeable concrete partition wall.
[0004] However, in actual use, the above-mentioned riverbank protection structures do not retain rainwater, and remain wet for a short time after rain, requiring external spraying for water supply afterward. This does not truly achieve rainwater recycling and increases operating costs. In view of this, we propose a concrete slope protection structure for water conservancy river management. Utility Model Content
[0005] The purpose of this utility model is to provide a concrete slope protection structure for water conservancy and river channel management, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete slope protection structure for water conservancy and river channel management, comprising a concrete slope protection body, a water channel being formed at the bottom of the concrete slope protection body, and an irrigation component being provided inside the concrete slope protection body, the irrigation component comprising:
[0007] A filter plate is installed on the inner wall of the concrete slope protection body. A sedimentation tank is installed on the bottom surface of the concrete slope protection body. A guide plate is fixedly connected to the inner wall of the concrete slope protection body. A water supply pipe is fixedly connected to the inner wall of the concrete slope protection body.
[0008] The permeable concrete has a support frame 1 fixedly connected to its outer wall, a permeable geotextile fixedly connected to the end of the support frame 1 away from the permeable concrete, and a support frame 2 fixedly connected to the end of the permeable geotextile fixedly away from the support frame 1.
[0009] Preferably, the top of the concrete slope protection body is provided with a slot, and the inner bottom surface of the slot abuts against the concrete slope protection body.
[0010] Preferably, the permeable concrete is fixedly connected to the inner wall of the concrete slope protection body, and the inner wall of the support is provided with graded crushed stone, which further reduces the rate at which water seeps into the planting soil.
[0011] Preferably, the inner wall of the second support is provided with planting soil, and green plants are planted on top of the planting soil. The green plants filter the water and at the same time green the slope.
[0012] Preferably, the sidewall of the sedimentation tank is fitted to the inner wall of the concrete slope protection body, and the water supply pipe is located between the sedimentation tank and the guide plate.
[0013] Preferably, a water storage cavity is provided between the permeable concrete and the concrete slope protection body, and the water storage cavity is connected to a water supply pipe.
[0014] Preferably, the permeable concrete, support one, permeable geotextile and support two have overflow channels on their side walls, and the overflow channels are connected to the water storage cavity.
[0015] Compared with the prior art, this utility model provides a concrete slope protection structure for water conservancy and river channel management, which has the following beneficial effects:
[0016] 1. The concrete slope protection structure used in this water conservancy and river channel management, through the installation of irrigation components, prevents large particles such as leaves, plastic bags, and mud from entering. These impurities settle into the sedimentation tank, and impurities in the water supply pipe also settle into the sedimentation tank. Gravity enhances the secondary sedimentation effect, improves water quality, prevents water supply pipe blockage, and results in cleaner effluent. The water storage chamber first regulates the flow, and the permeable concrete acts as the initial flow limiter. The subsequent gravel layer and geotextile continue to buffer and filter, eventually infiltrating into the planting soil to become an absorbable water source for the turf roots, improving rainwater utilization and reducing reliance on artificial irrigation.
[0017] 2. The concrete slope protection structure used for water conservancy and river management diverts rainwater before the filter plate is submerged by rainwater through the overflow channel. The water is then safely guided into the water storage chamber inside the concrete slope protection body and discharged through the overflow channel, while garbage is still intercepted in the filtration area, thus protecting the water environment.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a concrete slope protection structure for water conservancy and river management, including a concrete slope protection body 1, a water flow channel 2 at the bottom of the concrete slope protection body 1, and an irrigation component 3 inside the concrete slope protection body 1. The irrigation component 3 includes a filter plate 301, a sedimentation tank 302, a guide plate 303, a water conveying pipe 304, permeable concrete 305, a support first 306, graded crushed stone 307, permeable geotextile 308, a support second 309, planting soil 310, and a water storage cavity 311.
[0025] In one embodiment of this utility model, a filter plate 301 is disposed on the inner wall of the concrete slope protection body 1. A slot is provided on the top of the concrete slope protection body 1, and the inner bottom surface of the slot abuts against the concrete slope protection body 1. A sedimentation tank 302 is disposed on the inner bottom surface of the concrete slope protection body 1. A guide plate 303 is fixedly connected to the inner wall of the concrete slope protection body 1. A water supply pipe 304 is fixedly connected to the inner wall of the concrete slope protection body 1. The side wall of the sedimentation tank 302 is in contact with the inner wall of the concrete slope protection body 1. The water supply pipe 304 is located between the sedimentation tank 302 and the guide plate 303.
[0026] The permeable concrete 305 is fixedly connected to the outer wall of the permeable concrete 305 by a support 306. A permeable geotextile 308 is fixedly connected to the end of the support 306 away from the permeable concrete 305. A support 309 is fixedly connected to the end of the permeable geotextile 308 away from the support 306. The permeable concrete 305 is fixedly connected to the inner wall of the concrete slope protection body 1. The inner wall of the support 306 is provided with graded crushed stone 307, which further reduces the rate of water infiltration into the planting soil 310. The inner wall of the support 309 is provided with planting soil 310, and green plants are planted on the top of the planting soil 310. The green plants filter the water and green the slope protection. A water storage cavity 311 is provided between the permeable concrete 305 and the concrete slope protection body 1. The water storage cavity 311 is connected to the water supply pipe 304.
[0027] The filter plate 301 first filters the rainwater, preventing large impurities or garbage washed by the rainwater from falling into the interior of the concrete slope protection body 1. It also prevents large particles such as leaves, plastic bags, and mud from entering and clogging the concrete slope protection body 1. The rainwater settles inside the concrete slope protection body 1, and the impurities settle into the sedimentation tank 302. The top of the sedimentation tank 302 is fixedly connected to a handle, which can be pulled out to clean the sediment, improve water quality, reduce maintenance frequency, reduce the burden on the filtration system, and extend its service life.
[0028] Rainwater flows upwards into the water pipe 304. Because the water pipe 304 is inclined upwards, impurities in the water pipe 304 are further settled and fall into the sedimentation tank 302. Gravity enhances the secondary sedimentation effect, improves water quality, prevents the water pipe 304 from being blocked, and results in cleaner effluent. This is beneficial for subsequent infiltration and absorption by the grass roots, and prevents the formation of silt or sediment blockage. Rainwater then flows upwards into the water storage chamber 311, and then slowly infiltrates through the permeable concrete 305 into the graded crushed stone 307. Rainwater then slowly infiltrates into the planting soil 310 through the graded crushed stone 307 and permeable geotextile 308, achieving multi-stage deceleration infiltration of rainwater. Rainwater is not lost all at once, but is gradually retained and absorbed. The water storage chamber 311 first regulates the water, the permeable concrete 305 plays the first role in limiting the flow, and the subsequent crushed stone layer and geotextile continue to play the role of buffering and filtering. Finally, the rainwater infiltrates into the planting soil 310 and becomes an absorbable water source for the turf roots, improving the rainwater utilization rate and reducing the dependence on artificial irrigation.
[0029] In addition, overflow channels 4 are provided on the side walls of permeable concrete 305, support 1 306, permeable geotextile 308 and support 2 309. The overflow channels 4 are connected to the water storage chamber 311. During heavy rain, a large amount of rainwater may carry surface garbage such as leaves, plastic bags, beverage bottles, and cigarette butts. If overflow occurs above the filter plate 301, the garbage may directly enter the river from above the filter plate 301. The overflow channels 4 can divert rainwater before the filter plate 301 is submerged by rainwater, allowing the water to be discharged through a safe path into the water storage chamber inside the concrete slope protection body 1 and the overflow channels 4, while the garbage is still intercepted in the filtration area, protecting the water environment.
[0030] In this invention, during use, the filter plate 301 first filters the rainwater, preventing large impurities or debris washed by the rainwater from falling into the interior of the concrete slope protection body 1. This prevents large particles such as leaves, plastic bags, and mud from entering and clogging the concrete slope protection body 1. The rainwater settles inside the concrete slope protection body 1 and then flows upwards into the water supply pipe 304. Because the water supply pipe 304 is inclined upwards, impurities in the water supply pipe 304 are further settled and fall into the sedimentation tank 302. Gravity enhances the secondary sedimentation effect, improves water quality, and prevents the water supply pipe 304 from becoming clogged. The outflowing water is cleaner. Rainwater flows upward into the water storage chamber 311, and then slowly infiltrates through the permeable concrete 305 into the graded crushed stone 307. The rainwater then slowly infiltrates through the graded crushed stone 307 and the permeable geotextile 308 into the planting soil 310, achieving multi-stage deceleration infiltration of rainwater. The rainwater is not lost all at once, but is slowly retained and absorbed step by step. The water storage chamber 311 first regulates the flow, the permeable concrete 305 plays the first role in limiting the flow, and the subsequent crushed stone layer and geotextile continue to play the role of buffering and filtering. Finally, it infiltrates into the planting soil 310 and becomes an absorbable water source for the turf roots, improving the rainwater utilization rate.
[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
