Description

Technical Field

[0001] The invention relates to the technical field of river channel slope protection, and in particular to a river channel ecological slope protection structure and method for a water conservancy project. Background Art

[0002] River ecological slope protection is mainly used to reinforce the river channel. It covers the river channel soil with concrete or bricks to prevent the river channel from collapsing due to soil erosion under the action of water flow. At the same time, planting green plants on the slope protection can also maintain the beauty of the river channel.

[0003] The existing river channel ecological slope protection is mainly made by simple bricklaying reinforcement. Since the brick structure is simple and easy to fall off after fitting, the protective performance is not good and requires frequent maintenance. At the same time, there is also a lack of water storage structure, which makes it easy for green vegetation to die due to lack of water during droughts due to factors such as untimely irrigation. This also leads to the difficulty of maintaining the river channel ecological slope protection and high maintenance costs in the later stage. Therefore, it is difficult to meet the existing use needs. For example, the patent with application number CN111778925A and patent name "A river channel ecological slope protection and its construction method" provides this type of ecological slope protection formed by a simple combination of bricks and vegetation. Although it realizes the rapid laying and reinforcement of the river channel ecological slope protection, it still cannot solve the above problems.

[0035] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0036] Embodiment 1, the present invention provides a technical solution: a water conservancy project river ecological slope protection structure, please refer to Figures 1 to 7 , including a support base 1, a bearing frame 29 and a water reservoir 33. The support base 1 is arranged on a rammed earth layer 10, and a foundation pile 4 inserted into the rammed earth layer 10 is arranged on the support base 1. The upper end of the support base 1 is connected to a top support seat 25 through a support column 11, and a water receiving ditch 15 is formed between the support base 1 and the top support seat 25, and a first filtering filler 21 for filtering water is arranged in the water receiving ditch 15. The support base 1, the bearing frame 29 and the top support seat 25 are all formed by casting reinforced concrete, wherein the bearing frame 29 is assembled by prefabricated panels.

[0037] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6The support frame 29 is obliquely installed on the top of the support base 1 and the top support seat 25, and the top of the support frame 29 is densely paved with a fixing device 3, and the fixing device 3 is filled with a planting filler 35 for planting green plants, and a water drop cavity 40 is formed between the support frame 29 and the support base 1. The water seeping from the planting filler 35 drips into the water drop cavity 40 through the drip hole 26 arranged on the support frame 29. The water drop cavity 40 is used to collect and store irrigation water and rainwater, and the water ditch 15 is connected to the water drop cavity 40 through the water guide channel 12 arranged between the support base 1 and the top support seat 25. The planting filler 35 is a loam layer, a sand layer and a pebble layer from top to bottom, and a plastic mesh plate for lifting the pebble layer is arranged on the top of the drip hole 26 When the planting filler 35 is irrigated, the water is mainly retained by the loam layer and the sand layer. When the water content in the loam layer and the sand layer is too high and water seeps out, the water flows through the pebble layer and then enters the water drop cavity 40 through the drip hole 26. The pebble layer is mainly used to support the sand layer and does not need to retain water. The pebble layer can also be filled with crushed stones or resin particles as needed to further prevent the sand in the sand layer from falling into the drip hole 26. It only needs to ensure that the filled pebbles, crushed stones or resin particles are larger than the mesh diameter of the mesh plate installed on the drip hole 26. The top of the capillary 27 is evenly distributed between the loam layer and the sand layer. When the water content in the loam layer and the sand layer is too low, the capillary 27 can use capillary action to move the water in the drip cavity 40. The water in the cavity 40 is pumped into the loam layer and the sand layer, thereby maintaining the moisture content in the loam layer and the sand layer, and the water in the water cavity 40 will also become water vapor under the action of evaporation and pass through the drip holes 26 into the planting filler 35, thereby being absorbed by the loam layer and the sand layer with lower moisture content. Therefore, it is only necessary to ensure that there is a certain amount of water in the water cavity 40 to maintain the moisture content in the planting filler 35 at a certain standard. The top support seat 25 is provided with a water retaining platform 23 for retaining water at the side of the corresponding water receiving ditch 15, and a water diversion port 22 is provided on the water retaining platform 23. The support frame 29 is integrally formed with a guide plate 24 that cooperates with the water diversion port 22 and is used to guide the water flowing out of the water diversion port 22 to the fixing device 3. Rainwater or irrigation After the irrigation water enters the water receiving ditch 15, a part of it will be filtered by the filter filler 21 and then enter the water cavity 40 through the water guide channel 12. However, due to the filtration speed of the filter filler 21, when the water flow rate entering the water receiving ditch 15 is large, the water level in the water receiving ditch 15 will rise. When the water level rises above the water diversion port 22, the water will pass through the water diversion port 22 and enter between the guide plates 24. At this time, the water will be sent into the fixing device 3 along the guide plate 24. Since the supporting frame 29 is installed at an angle and the end close to the water receiving ditch 15 is higher, the water will traverse each fixing device 3 and then flow into the river. When the water traverses each fixing device 3, the water will be absorbed by the planting filler 35 located in each fixing device 3.When the amount of water absorbed by the planting filler 35 exceeds the required amount, the water will flow along the drip holes 26 into the water cavity 40, thereby maximizing the use of the water.

[0038] See also Figure 1 , Figure 2 and Figure 4 At least two support isolation frames 8 for supporting the carrier frame 29 are arranged at different heights in the middle of the support base 1 in the water cavity 40, and at least two water reservoirs 33 with height differences are arranged in the water cavity 40 at positions staggered with the support isolation frames 8, and the water reservoirs 33 transport water to the planting filler 35 through the capillary action of the capillary tubes 27 arranged in the drip holes 26, and the support isolation frames 8 are provided with drainage holes 7 for connecting the two water reservoirs 33. The water reservoirs 33 are arranged at different heights so that the capillary tubes 27 can be in close contact with the water flow in the corresponding water reservoirs 33, thereby maximizing the capillary effect. The capillary action of the tube 27 avoids the problem of unclear capillary action due to the capillary tube being too long. At the same time, the water storage tank 33 arranged in this stepped manner can also prevent the water flow from being completely deposited at the bottom of the water drop cavity 40. If the water flow is completely located at the bottom of the water drop cavity 40, when the broken surface of the slope protection is wider, in order to maintain the water storage capacity in the water drop cavity 40, the green vegetation located at the lower position may be submerged by the water in the water drop cavity 40. The water storage tank 33 arranged in a stepped manner for storing water at different heights can store water at different heights, thereby avoiding the problem of low-lying green vegetation being submerged by water while maintaining the water storage capacity.

[0039] See also Figure 1 , Figure 2 and Figure 4A filter chamber 32 is formed between the support isolation frame 8 and the support base 1 at the bottom of the water cavity 40, and a water exchange channel 31 for connecting the filter chamber 32 and the river bottom is provided on the support base 1. The water exchange channel 31 and the filter chamber 32 are filled with a second filter filler 30, and different horizontal positions of the same water reservoir 33 are separated by an inner partition 5 to form unit pools with equal length distribution. Considering that the river bank is long and the terrain height will also change, the same water reservoir 33 will also have a height difference in the length direction, so By using the inner partition 5 to divide the same water reservoir 33 into different unit pools in the length direction, it is possible to ensure that water can be stored in all parts of the water reservoir 33, and the phenomenon of water flow converging in the low-lying part of the water reservoir 33 will not occur. In addition, the inner cavity surfaces of the water reservoir 33 and the filter cavity 32 are both waterproof, so as to prevent water from flowing through the support base 1 through osmosis. The filter cavity 32 and the water reservoir 33 located at the lowest point in the water drop cavity 40 are connected through the drainage hole 7 set on the support isolation frame 8. The first filter filler 2 1 is composed of a crushed stone layer, a coarse sand layer, a fine sand layer and a pebble layer from top to bottom. The first filter filler 21 is mainly used for rainwater and irrigation water. Since the content of sediment in rainwater and irrigation water is relatively small, crushed stone and fine sand can be used for simple filtration. A plastic mesh plate for supporting the first filter filler 21 is provided on the top of the water guide channel 12. The plastic mesh plate is used to prevent the first filter filler 21 from falling into the water guide channel 12 and blocking the water guide channel 12. The second filter filler 30 is oriented from one side of the filter cavity 32 toward the river. The bottom side is composed of a pebble layer, a coarse sand layer and a gravel layer in sequence. The second filter filler 30 is mainly used to filter the silt and gravel in the river water. Considering that there is too much silt at the bottom of the river and the filtering effect is poor, the purpose of filtering is more to prevent the silt from entering the bottom of the water cavity 40 quickly and in large quantities. At this time, the filling amount of the second filter filler 30 is mainly increased to increase the path of the silt from the river bottom into the water cavity 40. The silt that cannot be avoided from entering the bottom of the water cavity 40 can only be regularly sucked out by a sludge pump.In addition, connecting the filter chamber 32 to the river bottom through the water exchange channel 31 can maintain the water level. When the river is at a normal water level, the water level of the river surface should be kept lower than the planting filler 35 at the bottom but higher than the water level at the bottom of the water cavity 40. At this time, when the external weather is dry for a long time, the water in the river will enter the filter chamber 32 through the water exchange channel 31, and then moisten the planting filler 35 through the drip hole 26 through evaporation, thereby avoiding the long-term lack of water and drying of green vegetation. When the external weather is dry for a long time, the water in the water cavity 40 will be moistened. When the rising water level in 40 easily causes the water in the water cavity 40 to submerge the planting filler 35 and cause the roots of the green vegetation to rot, the water in the water cavity 40 can also directly enter the riverbed through the water exchange channel 31, thereby preventing the water level in the water cavity 40 from exceeding the required level. When the river dries up, the water artificially irrigated through the water receiving ditch 15 will also preferentially enter the various water reservoirs 33 along the various drainage holes 7 in turn after entering the water cavity 40 and be stored instead of directly entering the riverbed, thereby effectively playing the role of water storage and drought resistance.

[0040] See also Figure 1 , Figure 2 and Figure 3A pipeline channel 13 is provided in the support base 1, and a water and electricity pipeline 14 is provided in the pipeline channel 13, a first water pump 28 is provided in the pipeline channel 13, and the inlet end of the first water pump 28 is connected to the tap water pipe in the water and electricity pipeline 14, an equipment channel 17 is provided in the support base 1, and a main controller 39 is provided in the equipment channel 17, the main controller 39 is electrically connected to the cable in the water and electricity pipeline 14, and a maintenance cover 19 for connecting to the equipment channel 17 is provided on the support base 1, a second water pump 38 is provided in the equipment channel 17, and a water filter device 2 connected to the water inlet end of the second water pump 38 is provided in the filter chamber 32, and the filter The water device 2 includes a box body 205, and the box body 205 is divided into a water inlet chamber 204 and a water filter chamber 202 by a rear filter 201 and a front filter 203, the water inlet chamber 204 is connected to the inlet end of the second water pump 38, and the water filter chamber 202 is filled with activated carbon, a water spray head 20 for supplying water to the water inlet ditch 15 is provided in the water receiving ditch 15, and the water outlet end of the first water pump 28 and the water outlet end of the second water pump 38 are both connected to the water spray head 20, each water reservoir 33 is provided with a first liquid level detection sensor 6 for detecting the water level in the water reservoir 33, and a second liquid level detection sensor 6 for detecting the water level in the filter chamber 32 is fixedly installed in the filter chamber 32 The detection sensor 9 and the main controller 39 are electrically connected to the first water pump 28, the second water pump 38, the first liquid level detection sensor 6 and the second liquid level detection sensor 9 respectively. The main controller 39 can directly detect the water levels in the water reservoir 33 and the filter chamber 32 through the first liquid level detection sensor 6 and the second liquid level detection sensor 9. When the water levels in the water reservoir 33 and the filter chamber 32 are very low, it is judged that it is a drought period. The main controller 39 will give priority to the irrigation water supplied by the water and electricity pipeline 14 through the first water pump 28 to drain the water into the connecting ditch 15, so that the irrigation water can be discharged through the connecting ditch 15 and the water guide channel 1 2 enters the water reservoir 33. When it is detected that the water level in the water reservoir 33 is low and the water level in the filter chamber 32 is high, the second water pump 38 is used to directly extract the water in the filter chamber 32 to add water to the water reservoir 33. A sensor for detecting soil moisture electrically connected to the main controller 39 can also be set in the planting filler 35. When it is detected that the soil moisture is low, the water flow rate per unit time of the first water pump 28 or the second water pump 38 can be increased, so that more water flows directly across the water diversion port 22 into the fixing device 3 to irrigate the green vegetation, thereby achieving direct irrigation of the green vegetation.

[0041] Therefore, the river channel ecological slope protection structure designed by the present invention can not only effectively protect the river channel by using the support base 1 to prevent rainwater from directly scouring the rammed earth layer 10 and causing soil erosion, but also can use the reservoir 33 to store water flow to prevent green vegetation from dying due to lack of water. At the same time, the first water pump 28, the second water pump 38 and the water exchange channel 31 can automatically maintain the water level of the reservoir 33 and the humidity in the planting filler 35, and maintain the water level balance between the water cavity 40 and the river, so it can effectively play a protective role on the river bank and the maintenance role on the green vegetation. It solves the problem that the existing river channel ecological slope protection has poor protection ability and lacks water storage and maintenance function for green vegetation, and can effectively reduce the maintenance pressure of the river channel ecological slope protection.

[0042] For example 2, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 On the basis of the first embodiment, the fixing device 3 includes a regular hexagonal cylinder 303, and the regular hexagonal cylinder 303 is filled and installed on the carrier 29 in a plane densely paved form, the bottom of the regular hexagonal cylinder 303 is integrally formed with a plug seat 305, and the carrier 29 is provided with a plug hole 34 plugged and installed with the plug seat 305, the top of the regular hexagonal cylinder 303 is integrally formed with a water retaining protrusion 301 for retaining water, and a water guide port 302 is formed between the water retaining protrusions 301, and at least three water permeable holes 304 are arranged in an array from top to bottom on the six faces of the regular hexagonal cylinder 303, and the fixing device 3 adopts a regular hexagonal The cylinder 303 can be easily paved, and the plug socket 305 can also prevent the fixing device 3 from falling off after being inserted into the plug hole 34. The setting of the water retaining protrusion 301 and the water guide port 302 can make the water flow flow to the inside of the adjacent fixing device 3 under the water guiding effect of the water guide port 302 when flowing through the water retaining protrusion 301, thereby making it more convenient to even out the water flow during irrigation. At the same time, the water guide port 302 set on the regular hexagonal cylinder 303 can also send the water flow in the regular hexagonal cylinder 303 into the adjacent fixing device 3, thereby making it more convenient to even out the water flow and make the water flow be effectively utilized. The problem of poor protection ability of the existing river ecological slope protection and lack of water storage and maintenance function for green vegetation is further solved, and the maintenance pressure of the river ecological slope protection can be effectively reduced.

[0043] For example 3, please refer to 1. Figure 2 and Figure 3On the basis of the second embodiment, a solar panel 18 is fixedly installed on the top of the support base 1, and an energy storage device 16 is installed in the equipment channel 17. The solar panel 18 is electrically connected to the energy storage device 16 through the photovoltaic controller 37 and the rectifier 36, and the energy storage device 16 and the photovoltaic controller 37 are both electrically connected to the main controller 39. The solar panel 18 can effectively use solar power generation to power the main controller 39, the first water pump 28, the second water pump 38 and other electrical components, thereby effectively using the idle area above the river bank to produce electricity to reduce the pressure on electricity consumption, and also make the first water pump 28 and the second water pump 38 not be unable to work normally due to power outages in the power grid, thereby delaying the normal irrigation and maintenance of green vegetation, and also realizing the full utilization of the river slope protection. It further solves the problem that the existing river ecological slope protection has poor protection capabilities and lacks water storage and maintenance functions for green vegetation, and can effectively reduce the maintenance pressure of the river ecological slope protection.

[0044] Embodiment 4, based on embodiment 3, the present invention further provides a method for using a river ecological slope protection structure of a water conservancy project, comprising the following steps:

[0045] Step 1: First, rammed earth layers 10 are set on both sides of the river channel, and then foundation piles 4 are set in the rammed earth layers 10, and then concrete is poured to form a support base 1, a top support seat 25 and a support isolation frame 8, and then the prefabricated bearing frame 29 that has been poured with reinforced concrete is placed on the top of the support base 1 and the top support seat 25 and assembled correctly, and then water is filled from the water receiving ditch 15 into the water cavity 40 until the water flow can fill all the water reservoirs 33;

[0046] Step 2: Lay the fixture 3 flat on the carrier 29, then place the corresponding capillary tube 27 into the corresponding water reservoir 33 through each drip hole 26, then fill the fixture 3 with planting filler 35, and ensure that the top of the capillary tube 27 can be correctly installed in the planting filler 35, then plant green plants in the planting filler 35 and directly water and fertilize the planting filler 35 to maintain the growth requirements of the plants;

[0047] Step three: regularly check the wetness of each planting filler 35 and the liquid level in the water reservoir 33 through the inspection hole additionally provided on the support frame 29, and then directly inject water into the water receiving ditch 15 when it is necessary to water the green plants or to inject water into the water reservoir 33, and control the flow rate during water injection to control the ratio of water flowing to the planting filler 35 and directly infiltrating into the water reservoir 33 through the first filter filler 21, so as to maintain the wetness of the planting filler 35 and the water level in the water reservoir 33. On rainy days, rainwater will be collected by the water receiving ditch 15 and the fixing device 3 and sent into the water drop cavity 40 through the water guide channel 12 and the drip hole 26, and when the wetness of the planting filler 35 is low, the water in the water reservoir 33 will also be absorbed through the capillary 27, so as to avoid the green plants from dying due to long-term lack of water.

[0048] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
