Description

Technical Field

[0001] The present invention belongs to the technical field of river ecological transformation, and particularly relates to an ecological transformation method for a rigid riverbank. Background Art

[0002] In traditional water conservancy project construction, the construction goal of a river is mainly to meet flood control requirements. In order to improve the flood discharge and anti-scour capabilities of the river, a structural form of a rigid riverbank such as concrete is often adopted. With the construction of ecological civilization in China, the traditional rigid riverbank blocks the ecological connectivity between water and land, and has a negative impact on the biodiversity in the water body. As people's requirements for the living environment and a beautiful ecological environment are getting higher and higher, the "three-sided smooth" form of the rigid river also seriously affects the city appearance. Therefore, it is necessary to carry out ecological transformation on the rigid riverbank.

[0003] In the prior art, for the ecological construction of a rigid riverbank, green plants or vine plants are usually directly planted on the slope of the rigid riverbank (the top of the slope is a platform) to cover the entire slope. The ecological construction in this way is relatively single, and the vegetation cannot resist flood disasters and is greatly affected by seasonal changes, with poor practicability. In addition, the plants far from the water body (close to the top of the slope) cannot absorb much water, grow relatively sparsely, resulting in visual differences, and because the rigid riverbank is long, it is not convenient for unified irrigation, with poor practicability.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Please refer to Figures 1 to 5 together, and now a method for ecological transformation of a hard riverbank provided by the present invention will be described. The method for ecological transformation of the hard riverbank includes the following steps:

[0030] S100: Dig a canal, build a water storage canal 10 along the length direction of the hard riverbank 50 on the top platform of the hard riverbank 50, and perform anti-seepage treatment on the water storage canal 10.

[0031] S200: Install pipes. Open a number of perforations that communicate with the river channel and are horizontally arranged in the water storage canal 10. Each perforation is evenly distributed in the vertical direction, and a water guide pipe 20 is placed in each perforation.

[0032] S300: Install water storage regulation. Install a plurality of water storage regulation mechanisms 30 in the water storage canal 10, and make each water storage regulation mechanism 30 correspond to the end of each water guide pipe 20 one by one, so that the water collected in the water storage canal 10 is discharged in each water guide pipe 20 from top to bottom. And

[0033] S400: Lay greenery. Lay a plurality of green plant boxes 40 on the slope of the hard riverbank 50, and connect and communicate any two adjacent green plant boxes 40. Along the horizontal direction, make each green plant box 40 corresponding to each water guide pipe 20 communicate with the end of each water guide pipe 20 one by one to receive the water led out by the water guide pipe 20.

[0034] Compared with the prior art, the method for ecological transformation of the hard riverbank provided by this embodiment can cover the entire hard riverbank 50 with a plurality of green plant boxes 40, which can provide a planting environment for ecological plants. And due to the independent setting of each green plant box 40, it can meet the planting or cultivation of various green plants with seasonal changes, thereby ensuring the diversity of ecological construction. At the same time, in rainy days, the water storage canal 10 collects the surface runoff of the initial rainwater, and its pollutant concentration is relatively high. It can be used as the greening water for the plants in the green plant box 50 on sunny days, and the pollutants in the initial rain are reduced through biological action, reducing the non-point source pollution problem in rainy days. Moreover, the water storage canal 10 built at the top of the hard riverbank 50 can ensure the collection of water resources such as rainwater, and can directly transfer the water to each green plant box 40 through the water guide pipe 20, which can ensure the sufficiency of water in each green plant box 40, and thus ensure the growth of green plants. In addition, the setting of the water storage canal 10 can also ensure the unified irrigation of green plants, and has strong practicability.

[0035] It should be noted that after the water storage channel 10 is opened and the water storage and regulation installation steps are completed, the open mouth of the water storage channel 10 can be covered with a concrete slab or a steel plate with leakage holes. This technology is an existing technology and will not be elaborated here. In the dry season, water in the river channel can also be pumped into the water storage channel 10 through a water pump to ensure uniform irrigation of the green plant boxes 40.

[0036] In some embodiments, the above-mentioned green plant box 40 can adopt the structure as Figure 2 shown. Refer to Figure 2 . Each green plant box 40 includes a box body 41, a flexible telescopic pipe 42, and a vegetation body located inside the green plant box 40. The box body 41 has a cuboid outer shape structure. The box body 41 has an open cavity for placing the vegetation body. The box body 41 has four side wall surfaces with the same specifications. Plug-in male ends 411 are provided on two adjacent side wall surfaces, and plug-in female ends 412 are provided on the other two adjacent side wall surfaces. Water inlets communicating with the open cavity are provided at the bottom ends of the box body 41. One end of the flexible telescopic pipe 42 is communicated with the water inlet, and the other end is communicated with the corresponding water guide pipe 20. The open cavity can ensure the placement of the vegetation body and prevent soil and water loss at the same time.

[0037] The plug-in male ends 411 and the plug-in female ends 412 can ensure that the box bodies 41 can be detachably connected, effectively improving the stability of the overall structure and ensuring resistance to flood disasters. The flexible telescopic pipe 42 has the characteristic of universal connection, which can ensure the connection with the water guide pipe 20. Preferably, the two adopt a threaded connection structure.

[0038] In this embodiment, the cross-section of the box body 41 in the normal direction of the slope of the rigid river bank 50 is a square, which is convenient for the connection between the box bodies 41.

[0039] In this embodiment, each side wall top end of the box body 41 has a notch. Along the inclined direction of the slope, the notches are located on the same straight line, which can realize the communication between the box bodies 41 and ensure the outflow of the accumulated water in the top box body 41.

[0040] In some embodiments, the above-mentioned green plant box 40 can adopt the structure as Figure 5 shown. Refer to Figure 5 . Each green plant box 40 further includes fixing bolts 44. There are multiple fixing bolts 44, and the fixing bolts 44 are evenly distributed at the bottom of the box body 41 and are used to fix the box body 41 on the slope of the rigid river bank 50. Through the fixing bolts 44, the box body 41 can be fixed on the slope of the rigid river bank 50, thereby ensuring the stability of the box body 41 and ensuring its resistance to flood disasters.

[0041] Among them, multiple through holes corresponding to the fixing bolts 44 one by one are provided at the bottom of the open cavity.

[0042] In some embodiments, the above-mentioned green plant box 40 may adopt the structure as shown in Figure 5 . Refer to Figure 5 . The male plug end 411 includes a compensation part and a limiting part. One end of the compensation part is fixedly arranged on the side wall surface, and the other end extends out. The limiting part is fixedly arranged at the extending end of the compensation part. Along the length direction of the side wall surface, the length of the limiting part is greater than that of the compensation part. The female plug end 412 includes a notch adapted to the compensation part and a clamping port adapted to the limiting part. The notch may be located on one of the side walls of the box body 41, and the clamping port may be located in the open cavity. The structures of the male plug end 411 and the female plug end 412 can ensure the convenient assembly of each box body 41, and further ensure the overall stability.

[0043] In some embodiments, the above-mentioned water storage canal 10 may adopt the structure as shown in Figure 2 . Refer to Figure 2 . The cross-section of the water storage canal 10 is rectangular. The water storage canal 10 with this kind of structure is convenient to build, has a simple structure and strong practicability.

[0044] In some embodiments, the above-mentioned water storage regulating mechanism 30 may adopt the structure as shown in Figures 3 to 4 . Refer to Figures 3 to 4 . Each water storage regulating mechanism 30 includes a guiding frame 31, a sliding cover 32, a first floating ball 33, a secondary cover 34 and a second floating ball 35. There are two guiding frames 31, and both guiding frames 31 are fixedly arranged on the side walls inside the water storage canal 10 and are respectively located on both sides of the corresponding water guiding pipe 20. Each guiding frame 31 is provided with a long sliding opening arranged along the vertical direction, and the two long sliding openings form a sliding space in combination. The sliding cover 32 is slidably arranged in the sliding space. There is at least one first floating ball 33. The first floating ball 33 is located above the sliding cover 32 and is connected to the sliding cover 32 through a first connecting rod 36, and is used to drive the sliding cover 32 to move upward as the liquid level in the water storage canal 10 rises, so as to block the pipe orifice of the corresponding water guiding pipe 20. A communication port is arranged on the sliding cover 32. The communication port penetrates through the sliding cover 32 along the length direction of the water guiding pipe 20, and a sliding cavity 38 communicated with the communication port is arranged inside the sliding cover 32. The secondary cover 34 is slidably arranged in the sliding cavity 38 along the vertical direction. The second floating ball 35 is located above the sliding cover 32. The second floating ball 35 is connected to the secondary cover 34 through a second connecting rod 37, and is used to pull the secondary cover 34 to move upward to block the communication port after the sliding cover 32 blocks the water guiding pipe 20 as the liquid level in the water storage canal 10 continues to rise, or to move downward synchronously with the secondary cover 34 to open the communication port as the liquid level in the water storage canal 10 drops.

[0045] The long sliding opening on the guiding frame 31 can ensure the limiting sliding connection of the sliding cover 32. In the initial state, the sliding cover 32 is located below the water guide pipe 20. When the water level in the water storage channel 10 rises, the first floating ball 33 also rises accordingly, and then drives the sliding cover 32 to block the water guide pipe 20. This structure can ensure that the water in the water storage channel 10 is first discharged through the top water guide pipe 20. When the liquid level is lower than the height of the top water guide pipe 20, it is then discharged through the water guide pipe 20 lower than the top water guide pipe 20, which can ensure that the water in the water storage channel 10 can cover a large area of the green plant boxes 40. At the same time, it can control the water flow in the water storage channel 10 and the water pressure of the discharge, ensuring that the water can flow out slowly. When the liquid level is lower than the height of the top water guide pipe 20, in order to ensure that the water can be discharged, the second floating ball 35 will also drop, and under the action of gravity, the auxiliary cover 34 will move downward, and the communication port will be opened. At this time, the water can be discharged through the corresponding water guide pipe 20. When the liquid level is lower than the highest point of the first floating ball 33, the first floating ball 33 drops, and the sliding cover 32 moves downward, gradually opening the pipe orifice of the water guide pipe 20.

[0046] In this embodiment, the water storage and regulation mechanism 30 further includes a spring. The spring is located in the sliding cavity 38 and sleeved on the second connecting rod 37. The spring can bounce the auxiliary cover 34 downward after the water surface in the water storage channel 10 drops, so as to prevent the auxiliary cover 34 from being stuck in the sliding cavity 38 and ensure the opening of the communication port.

[0047] The sliding cover 32 and the auxiliary cover 34 can be made of resin material, and the floating ball can be made of hollow rubber material.

[0048] In some embodiments, the above-mentioned water storage and regulation mechanism 30 can adopt the structure as Figure 4 shown. Refer to Figure 4 , the end of each water guide pipe 20 located in the water storage channel 10 is a first inclined surface structure 21, and a second inclined surface structure 321 adapted to the water guide pipe 20 is provided on the corresponding sliding cover 32. Refer to Figure 4 , the first inclined surface structure 21, that is, the pipe orifice of the water guide pipe 20, is an inclined opening, and the corresponding second inclined surface structure 321 is an inclined surface shape adapted to the inclined opening. This structure can ensure the tight sealing of the sliding cover 32 to the orifice of the water guide pipe 20.

[0049] In some embodiments, the above-mentioned water storage and regulation mechanism 30 can adopt the structure as Figure 3 shown. Refer to Figure 3 , the length of the first connecting rod 36 is less than the length of the second connecting rod 37. This structure can ensure that the floating height of the second floating ball 35 is higher than the height of the first floating ball 33, and then can ensure the movement of the auxiliary cover 34 when the sliding cover 32 is fixed, ensuring that the water in the water storage channel 10 can flow out through the water guide rod.

[0050] In some embodiments, the above-mentioned water guide pipe 20 can adopt the structure as Figure 2The structure shown. Refer to Figure 2 , the water conduits 20 are evenly divided into multiple groups at intervals from top to bottom.

[0051] This embodiment can be understood as follows. Assuming that the water conduits 20 are divided into three groups from top to bottom, all the water conduits 20 in each group are flush in height and are arranged at intervals along the length direction of the water storage channel 10. This kind of structure can ensure the neat arrangement of the water conduits 20. In addition, in order to prevent interference between adjacent water storage and regulation mechanisms 30 in the vertical direction, the water conduits 20 in each group arranged at vertical intervals can be arranged in a staggered manner.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
