Description

Technical Field

[0001] This invention belongs to the field of ecological river technology, specifically an ecological waterway structure and its construction method. Background Technology

[0002] The river management incorporates the concept of ecological landscape river management, using the existing waterways as a medium to create a waterfront green belt through greening along both banks; using the roads on both banks as guides to connect nearby villages and scenic spots to form a riverside landscape chain; and using the folk culture of the riverside villages as the soul to form the project's own unique characteristics.

[0003] Rivers are important carriers of the aquatic ecological environment. River ecological management can ensure the biodiversity of the region, create habitats and breeding grounds for aquatic and amphibious animals, protect the aquatic ecological environment of rivers, improve the self-purification capacity of rivers, restore the function of natural river channels, and meet the needs of human survival.

[0004] To meet the requirements of protecting the aquatic ecological environment of rivers and improving their self-purification capacity, we propose an ecological and water-friendly river structure and its construction method.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an ecological and water-friendly river channel structure and its construction method to solve the above-mentioned problems in the prior art.

[0007] To achieve the above objectives, the present invention provides an ecological waterfront structure, including a retaining wall, a bank slope set above the retaining wall along the riverbank, and an asphalt road set on the top of the bank slope. The retaining wall includes a foundation for laying the bottom of the river channel and a retaining wall set on the foundation. A filter chamber is provided on the outer side of the inner side of the retaining wall.

The retaining plates are provided with a number of ventilation holes arranged in a regular pattern. The middle part of the upper half of the embankment slope is provided with a step. The top of the step is provided with a top cover.

[0011] In the technical solution of the present invention, the bank slope includes a walkway and an erosion-resistant biological blanket for planting water-fixing plants. A sewer is provided on the inner side of the bottom surface of the walkway. The erosion-resistant biological blanket consists of an impermeable layer, a soil covering layer and a soil and water conservation layer from bottom to top.

[0012] In the technical solution of the present invention, a diversion pipe structure is provided on the top of the outer side of the inner side of the embankment. The diversion pipe structure includes a first diversion pipe whose outer end is connected to the sewer, a second diversion pipe symmetrically arranged on the left and right sides connected to the inner end of the lower first diversion pipe, and a number of drip pipes whose top ends are connected to the second diversion pipe. The drip pipes pass through the corresponding planting trough and are inclined along the bottom surface of the planting trough.

[0013] In the technical solution of the present invention, the water inlet pipe is located at the bottom of the central axis of the slope of the embankment. The water inlet pipe includes a pipe body with a high outer end and a low inner end, and the inner end is connected to the water trough, as well as a second rotating plate mechanism located at the inner end of the pipe body. The second rotating plate mechanism includes a rotating plate, two blocks located at the front and rear sides of the rotating plate respectively, and a rotating shaft that vertically penetrates the rotating plate.

[0014] In the technical solution of the present invention, the right-side stop block is located in front of the rotating plate and the left-side stop block is located behind the rotating plate. The contact surfaces of the stop blocks and the rotating plate are respectively embedded with magnets that can attract each other. A rear blocking block is provided in the tube body behind the rotating plate.

[0015] In the technical solution of the present invention, the outer end of the rotating rod extends out of the embankment and the outer end of the rotating rod is provided with a protective cover for protecting the blades. The embankment is provided with an installation cavity on the inner side. The installation cavity is provided with rotating grooves symmetrically on the left and right sides. The gear set is provided in the installation cavity. The rotating convex plate is provided in the rotating groove and the rotating convex plates on both sides are staggered by 180°. The piston rod is provided with outwardly extending flanges symmetrically on the upper and lower sides of the rod wall.

[0016] In the technical solution of the present invention, the gear set includes a driving tooth that is coaxially fixed in the middle with the inner end of the rotating rod and driven teeth that are symmetrically arranged on the left and right sides and mesh with the driving tooth. The driven teeth are coaxially fixedly connected to the center of the larger diameter end of the rotating convex plate on the same side.

[0017] In the technical solution of the present invention, the dividing plate has a connecting hole at the bottom of the central axis. A filter plate is provided in the connecting hole near the water tank and a first rotating plate mechanism is provided on the side away from the water tank. The water outlet pipe is inclined with the outer end higher and the inner end lower, and the outer end of the water outlet pipe is connected to the return channel on the same side. A third rotating plate mechanism is provided in the water outlet pipe near the outer end. The first rotating plate mechanism, the second rotating plate mechanism and the third rotating plate mechanism have the same structure.

[0018] On the other hand, the present invention also provides a construction method for an ecologically friendly waterway structure, used in the above-mentioned ecologically friendly waterway structure, comprising the following steps:

[0019] I. Construction Preparation Stage

[0020] S1. Move and place the building materials required for the construction of the ecological river channel;

[0021] S2. After the materials are moved in, the land and slopes are leveled. Remove stones, weed roots and other debris from the construction surface. The slope must be cut and leveled according to the design requirements, and the slope surface must be compacted. If the soil contains harmful substances or the fill material contains a lot of rocks and boulders, a thin layer of topsoil free of small stones and debris should be laid evenly. The thickness of the topsoil should be greater than 10cm.

[0022] II. Construction Phase

[0023] S3. After the construction site is leveled as required, the foundation is poured with concrete. After the concrete dries, the revetment is built on the foundation using masonry. During the construction process from bottom to top, planting troughs, filter chambers, installation chambers and rotating troughs are reserved. At the same time, the filter components and diversion pipe structure are installed synchronously with the construction of the revetment. The walkway is poured with concrete on the top of the revetment.

[0024] S4. After the slope protection embankment is completed, an anti-erosion biological blanket consisting of an impermeable layer, a soil cover layer, and a soil and water conservation layer is laid on the slope surface from bottom to top. The impermeable layer is an impermeable geotextile, the soil cover layer is plain soil with hydrophilic vegetation planted in it, and the soil and water conservation layer is a polyamide soil and water protection layer. The anti-erosion biological blanket is constructed from the foot to the top and from downstream to upstream. The horizontal overlap is 5cm and the vertical overlap is 5cm. At the joint of the anti-erosion biological blanket, the upstream side should press down on the downstream side and the top side should press down on the foot side. It is fixed to the slope surface with ABS fixing nails, ABS connecting nails, and L-shaped nails.

[0025] S5. After the laying is completed, the ends are fixed. In order to prevent the erosion-resistant bio-mat from being washed away by the water or from shifting downwards by its own weight, the ends need to be treated. The top and bottom of the erosion-resistant bio-mat are fixed to the outside of the walkway and the inside of the asphalt road respectively by gabions.

[0026] S6. After construction is completed, fill the planting trough with plain soil, then install the mounting plate and retaining plate in sequence, and then plant hydrophilic vegetation in the planting trough.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In this invention, the water flow in the river channel drives the paddle to rotate. Under the transmission of the gear set, the rotating convex plate drives the piston rod to move back and forth and inflate and deflate the air bag. Then, the river water entering the water tank is squeezed into the return tanks on both sides, and returns to the return tank through the filter plate. The garbage is left in the water tank. Workers can open the top cover to clean it regularly, ensuring the ecological environment in the river channel and reducing ecological pollution.

[0029] 2. In this invention, planting troughs and erosion-resistant biological blankets are set up. By planting hydrophilic vegetation, nitrogen, phosphorus, potassium and other ions in the soil on both sides of the river are absorbed, preventing domestic and industrial sewage from directly seeping into the river and further improving the ability of the slope protection to purify the river water.

[0045] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0046] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0047] Reference Figures 1-9 As shown, an ecological waterfront structure of the present invention includes a retaining wall 1, a bank slope 2 set above the retaining wall 1 along the riverbank, and an asphalt road 3 set on the top of the bank slope 2. The retaining wall 1 includes a foundation 11 for laying the bottom of the river channel and a retaining wall 12 set on the foundation 11. A filter chamber 127 is provided on the outer side of the retaining wall 12. The filter chamber 127 is divided into a water trough 1271 in the middle and a return trough 1272 on the left and right sides by two left and right symmetrical dividing plates 1273.

[0048] The embankment 12 is equipped with a filter assembly 4, which includes an inlet pipe 41 for river water to flow into the filter chamber 127, a drive structure 42 for driving the river water to flow in the filter chamber 127, and two outlet pipes 43 for discharging river water. During high tide or high water, the river water will enter the inlet pipe 41 and, under the action of gravity, push the second rotating plate mechanism 412 to rotate counterclockwise to open the water flow into the water tank 1271.

[0049] The drive structure 42 includes a rotating rod 421, several blades 422 disposed near the inner end of the outer wall of the rotating rod 421 for driving the rotating rod 421 to rotate, airbag mechanisms 424 symmetrically arranged on the left and right sides of the outer end of the rotating rod 421, and a gear set 423 for transmitting power between the rotating rod 421 and the airbag mechanisms 424 on both sides. The airbag mechanism 424 includes a rotating cam 4241 that is transmitted to the gear set 423, a fixed tube 4242 located inside the rotating cam 4241, and a fixed tube 4242 located inside the rotating cam 4241 and the fixed tube 4242. The piston rod 4243 between the fixed tubes 4242 and the air bladder 4244 located at the outer end of the fixed tube 4242 are located in the water tank 1271. The inner end of the piston rod 4243 is fixed with a hemispherical ball 4243a. The edge of the rotating convex plate 4241 is provided with a groove 4241a that matches the ball 4243a. The outer end of the piston rod 4243 is located in the fixed tube 4242 and the end is provided with a piston 4243c that matches the inner diameter of the fixed tube 4242.

[0050] In use, the water flow in the river channel drives the rotating rod 421 to rotate via the paddle 422. The rotating rod 421, through the gear set 423, drives the rotating convex plates 4241 on both sides to rotate. Because the retaining ball 4243a at the inner end of the piston rod 4243 engages with the retaining groove 4241a on the edge of the rotating convex plate 4241, the rotating convex plate 4241 drives the piston rod 4243 to move back and forth. During the forward movement of the piston rod 4243, it pushes the piston 4243c to inflate the air bag 4244, thereby filling the water tank. The river water in 1271 is squeezed into the return channels 1272 on both sides. Under the pressure of the airbag 4244, the river water passes through the filter plate 1274 and pushes open the first rotating plate mechanism 1275, causing it to rotate counterclockwise. At this time, the river water enters the return channel 1272, while the garbage carried by the river water will remain in the water tank 1271. As the airbag 4244 increases, the water pressure at the bottom of the water accumulation in the return channel 1272 increases, and the third rotating plate mechanism in the outlet pipe 43 will also rotate counterclockwise and be squeezed open, so that the water pressure in the return channel 1272 is balanced.

[0051] Among them, such as Figure 3 As shown, the upper half of the embankment 12 has a trapezoidal cross section. Several planting troughs 121 are arranged in a matrix pattern on the upper side of the upper half of the embankment 12. An installation plate 122 is provided at the opening of the planting trough 121. A retaining plate 123 is provided on the installation plate 122. Several planting holes 1231 are provided along the horizontal central axis of the retaining plate 123. Several ventilation holes 1232 are regularly distributed on the retaining plate 123. A step 124 is provided in the middle of the upper half of the embankment 1. Workers can use the step 124 to trim and plant vegetation in the planting trough 121. A top cover 125 is provided at the top of the step 124. The bottom of the top cover 125 is connected to a water tank 1271, which allows workers to open the top cover 125 regularly to clean up the garbage remaining in the water tank 1271.

[0052] In addition, such as Figure 2 As shown, the bank slope 2 includes a walkway 21 and an erosion-resistant bio-mat 22 for planting water-fixing plants. The bottom surface of the walkway 21 has a sewer 211 on the inner side. The erosion-resistant bio-mat 22 consists of an impermeable layer 221, a soil covering layer 222, and a soil and water conservation layer 223 from bottom to top. The erosion-resistant bio-mat 22 protects the soil and water of the slope and can also be used to plant hydrophilic vegetation to protect the environment.

[0053] In addition, such as Figure 4As shown, a diversion pipe structure 126 is provided on the top of the outer side of the inner side of the embankment 12. The diversion pipe structure 126 includes a first diversion pipe 1261 whose outer end is connected to the sewer 211, a second diversion pipe 1262 symmetrically arranged on the left and right sides connected to the inner end of the first diversion pipe 1261, and several drip pipes 1263 whose top ends are connected to the second diversion pipes 1262. The drip pipes 1263 pass through the corresponding planting trough 121 and are inclined along the bottom surface of the planting trough 121. By setting the diversion pipe structure 126, the rainwater remaining in the sewer 211 can be directed to the planting trough 121, avoiding the situation where the bottom of the planting trough 121 is difficult to contact water.

[0054] In addition, such as Figures 8-9 As shown, the water inlet pipe 41 is located at the bottom of the central axis of the slope of the embankment 12. The water inlet pipe 41 includes a pipe body 411 with a high outer end and a low inner end, and the inner end is connected to the water tank 1271. The second rotating plate mechanism 412 is located inside the inner end of the pipe body 411. The second rotating plate mechanism 412 includes a rotating plate 4121, two blocks 4122 located on the front and rear sides of the rotating plate 4121 respectively, and a rotating shaft 4123 that vertically penetrates the rotating plate 4121. The upper and lower ends of the rotating shaft 4123 are vertically embedded in the inner wall of the water inlet pipe 41 and fixed. The rotating plate 4121 can rotate around the rotating shaft 4123.

[0055] Specifically, the right stop block 4122 is located in front of the rotating plate 4121, and the left stop block 4122 is located behind the rotating plate 4121. The contact surfaces of the stop blocks 4122 and the rotating plate 4121 are respectively embedded with magnets 4122a that can attract each other. The inner wall of the tube body 411 is fixed with a rear stop block 4124 behind the rotating plate 4121. After water enters the inlet pipe 41, under the action of gravity being greater than the magnetic force of the magnet 4122a, the rotating plate 4121 will be pushed to rotate counterclockwise by a certain angle until the rotating plate 4121 contacts the rear stop block 4124. At this time, the rotation angle of the rotating plate 4121 is less than 90° to avoid the rotating angle being too large, which would prevent the rotating plate 4121 from closing. After the river water enters the water tank 1271, the rotating plate 4121 rotates and closes again under the action of the magnetic force of the magnet 4122a to prevent the river water from flowing back from the inlet pipe 41 when the airbag 4244 expands.

[0056] In this embodiment, as Figures 5-6As shown, the outer end of the rotating rod 421 extends out of the embankment 12, and the outer end of the rotating rod 421 is provided with a protective cover 4211 to protect the blade 422 and prevent water plants from entangled in the blade 422. An installation cavity 128 is provided on the inner side of the embankment 12. Rotating grooves 129 are symmetrically arranged on both sides of the installation cavity 128. A gear set 423 is disposed within the installation cavity 128. A rotating convex plate 4241 is disposed within the rotating groove 129, and the rotating convex plates 4241 on both sides are staggered by 180°. The staggered rotating convex plates 4241 ensure that both sides... The piston rod 4243 moves back and forth synchronously, thereby ensuring that the expansion and contraction of the airbag 4244 are synchronized. The piston rod 4243 has symmetrically extended flanges 4243b on its upper and lower walls to prevent the piston rod 4243 from rotating. The gear set 423 includes a driving gear 4231 that is coaxially fixed to the inner end of the rotating rod 421 in the middle, and driven gears 4232 that are symmetrically arranged on the left and right sides and mesh with the driving gear 4231. The driven gears 4232 are coaxially fixed to the center of the larger diameter end of the rotating convex plate 4241 on the same side.

[0057] In addition, such as Figure 10 As shown, the dividing plate 1273 has a connecting hole 1273a near the bottom of the central axis. A filter plate 1274 is provided in the connecting hole 1273a on the side near the water tank 1271, and a first rotating plate mechanism 1275 is provided on the side away from the water tank 1271. When in use, as the airbag 4244 increases, the river water in the water tank 1271 will be squeezed into the return tank 1272 through the filter plate 1274. At the same time, the garbage will be left in the water tank 1271. The water outlet pipe 43 is inclined with the outer end higher and the inner end lower, and the outer end of the water outlet pipe 43 is connected to the return tank 1272 on the same side. A third rotating plate mechanism is provided in the outer end of the water outlet pipe 43. The first rotating plate mechanism 1275, the second rotating plate mechanism 412 and the third rotating plate mechanism have the same structure.

[0058] On the other hand, the present invention also designs a construction method for an ecological and hydrophilic river channel structure, including the following steps:

[0059] I. Construction Preparation Stage

[0060] S1. Move and place the building materials required for the construction of the ecological river channel;

[0061] S2. After the materials are moved in, the land and slopes are leveled. Remove stones, weed roots and other debris from the construction surface. The slope must be cut and leveled according to the design requirements, and the slope surface must be compacted. If the soil contains harmful substances or the fill material contains a lot of rocks and boulders, a thin layer of topsoil free of small stones and debris should be laid evenly. The thickness of the topsoil should be greater than 10cm.

[0062] II. Construction Phase

[0063] S3. After the construction site is leveled as required, the foundation 11 is poured with concrete. After the concrete dries, the revetment 12 is built on the foundation 11 using masonry. During the construction process from bottom to top, planting trough 121, filter chamber 127, installation chamber 128 and rotating trough 129 are reserved. At the same time, filter components 4 and diversion pipe structure 126 are installed synchronously with the construction of the revetment 12. The walkway 21 is poured with concrete on the top of the revetment.

[0064] S4. After the construction of the slope protection embankment 1 is completed, an anti-erosion biological blanket 22 consisting of an impermeable layer 221, a soil cover layer 222, and a soil and water conservation layer 223 is laid on the slope protection surface from bottom to top. The impermeable layer 221 is an impermeable geotextile, the soil cover layer 222 is plain soil with hydrophilic vegetation planted in it, and the soil and water conservation layer 223 is a polyamide soil and water protection layer. The anti-erosion biological blanket 22 is constructed from the foot to the top and from the downstream to the upstream direction. The horizontal overlap is 5cm and the vertical overlap is 5cm. At the connection of the anti-erosion biological blanket 22, the upstream side should press down on the downstream side and the top side should press down on the foot side. It is fixed to the soil slope surface with ABS fixing nails, ABS connecting nails, and L-shaped nails.

[0065] S5. After the laying is completed, the ends are fixed. In order to prevent the erosion-resistant bio-mat 22 from being washed away by the water or from shifting downwards by its own weight, the ends need to be treated. The top and bottom of the erosion-resistant bio-mat 22 are fixed to the outside of the walkway 21 and the inside of the asphalt road 3 respectively by gabions.

[0066] S6. After construction is completed, fill planting trough 121 with plain soil, then install mounting plate 122 and retaining plate 123 in sequence, and then plant hydrophilic vegetation in planting trough 121.

Construction Preparation Stage S1. Move and place the building materials required for the construction of the ecological river channel; S2. After the materials are moved in, the land and slopes are leveled. Remove the stones and weed roots from the construction surface. The slope must be cut and leveled according to the design requirements, and the slope surface must be compacted. If the soil contains harmful substances or the fill material contains a lot of rocks and boulders, a thin layer of topsoil free of small stones and debris should be laid evenly. The thickness of the topsoil should be greater than 10cm. II. Construction Phase S3. After the construction site is leveled as required, a foundation (11) is poured with concrete. After the concrete dries, a retaining wall (12) is built on the foundation (11) using masonry. During the construction process from bottom to top, planting troughs (121), filter chambers (127), installation chambers (128) and rotating troughs (129) are reserved. At the same time, filter components (4) and diversion pipe structures (126) are installed synchronously with the construction of the retaining wall (12). A walkway (21) is poured with concrete on the top of the retaining wall. S4. After the construction of the slope protection embankment (1) is completed, an anti-erosion biological blanket (22) consisting of an impermeable layer (221), a soil covering layer (222) and a soil and water conservation layer (223) is laid on the slope surface from bottom to top.
