Description

A construction method for ecological bank protection Technical Field

[0001] This invention belongs to the field of water conservancy construction technology, and specifically relates to a construction method for ecological bank protection. Background Technology

[0002] Ecological bank protection refers to a type of riverbank protection that uses plants or a combination of plants and civil engineering to prevent riverbank collapse, allow river water and soil to permeate each other, enhance the river's self-purification capacity, and create a certain natural landscape effect.

[0003] In response to the above, existing technologies for revetment construction firstly affect the construction process due to the influence of river water. Secondly, during the laying of geotextile, manual laying is prone to tilting, and the operation is cumbersome, requiring a lot of manpower for auxiliary laying, thus reducing laying efficiency and wasting time and effort. Summary of the Invention

[0004] The purpose of this invention is to solve the aforementioned technical problems existing in the prior art and to provide a construction method for ecological bank protection. This method involves dividing the bank protection along the river into sections and constructing in segments. First, a retaining wall is erected to separate the river water from the construction section. Then, a foundation trench is excavated and leveled. Next, geotextile is laid on the surface of the foundation trench in segments using a laying trolley. The end of the later-laid geotextile is pressed tightly onto the previously laid geotextile to ensure seamless connection between the geotextile layers. After the geotextile is laid, a layer of sand and gravel is filled in, followed by the installation of a steel mesh and the pouring of a concrete layer, ensuring the structural strength of the bank protection. A limiting hole is pre-reserved at the end of the bank protection closest to the river. The limiting block at the bottom of the limiting seat is inserted into the limiting hole for positioning and installation. Then, the bottom of the installation frame is fixed to the concrete layer. Finally, a grid is installed in the installation frame, dividing the frame into several planting troughs for planting greenery.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An ecological bank protection construction method includes the following steps:

[0007] a. Pre-construction preparation

[0008] First, the revetment along the line is divided into sections for construction. Then, a retaining wall is installed on the side of the revetment closest to the water. The water is then pumped out to separate the water from the bank.

[0009] b. Excavation of foundation trench

[0010] Excavate a foundation trench on one side of the revetment. First, excavate down to the bedrock, and then use a pickaxe to excavate to the design elevation and cross-section. Pay attention to the protection of the foundation pit during excavation, and use wooden piles for protection if necessary to ensure construction safety.

[0011] c. Foundation trench laying

[0012] (1) Foundation trench leveling

[0013] First, the bottom surface of the foundation trench is leveled using a flat roller. Then, new soil is backfilled and compacted. Next, the cleaned masonry stones are laid flat on the bottom surface of the foundation trench and laid in layers using the mortar bedding method. The gaps between the masonry stones are filled with mortar to make the surface smooth.

[0014] (2) Geotextile laying

[0015] Geotextile is laid on the surface of the foundation trench in sections using a laying trolley. When laying two adjacent geotextile pieces, the corresponding end of the later-laid geotextile is pressed tightly onto the previously laid geotextile.

[0016] (3) Concrete layer pouring

[0017] Now, a layer of sand and gravel is filled on the geotextile, and after the sand and gravel layer is sprayed with water, a steel mesh is erected, and then a concrete layer is poured.

[0018] d. Installation of the limit seat

[0019] During the concrete pouring process, a limiting hole is reserved at the installation location of the limiting seat at the end of the foundation trench near the water surface. After the concrete layer is cured, the limiting block of the limiting seat is installed through the limiting hole.

[0020] e. Setting up planting troughs

[0021] First, the installation frame is fixed on the base trench using a limiting seat. The bottom of the installation frame is fixed on the concrete layer. Then, a grid is installed inside the installation frame, which divides the area inside the installation frame into several planting trenches.

[0022] Furthermore, in step a, the specific structure of the retaining wall includes a water-retaining plate and a connecting rod. Fixed seats are installed on both sides of the foundation trench. One end of the connecting rod is movably connected to the fixed seat, and the water-retaining plate is lifted and lowered to the other end of the connecting rod. The connection rod and fixed seats enable the installation of the water-retaining plate. The connecting rod drives the water-retaining plate to slide and adjust, facilitating its insertion into the water. This allows the water between the water-retaining plate and the construction section to be pumped out, thus separating the water from the riverbank.

[0023] Furthermore, the mounting base has a through hole through which one end of the connecting rod passes. A tightening screw is located on the top of the mounting base, passing through the through hole and tightening onto the connecting rod. The through hole facilitates the sliding adjustment of the baffle plate by the connecting rod. By tightening the tightening screw onto the connecting rod, the connecting rod is fixed to the mounting base.

[0024] Furthermore, the baffle plate has sliding grooves on both sides, with sliders slidably connected within the grooves. A locking screw is located at the other end of the connecting rod, tightened onto the slider. An insertion part is located at the bottom of the baffle plate. When the height of the baffle plate needs to be adjusted, the locking screw is loosened, allowing the slider to slide within the groove, thus controlling the baffle plate's raising and lowering. After adjustment, the locking screw is tightened, clamping the connecting rod at both ends of the baffle plate, thereby fixing the baffle plate in place.

[0025] Furthermore, in step c, the specific structure of the laying trolley includes a frame, front wheels, and rear wheels. The front wheels are rotatably connected to both ends of the front end of the frame, and the rear wheels are rotatably connected to the rear side of the frame via a steering component. A feeding assembly is connected to the rear side of the top of the frame, and a clamping component is connected to the front side of the top of the frame. A guide component is connected to the top of the frame, located between the clamping component and the feeding assembly. The feeding assembly delivers the wound geotextile, which is then conveyed through the guide component to the front side of the frame. The geotextile is then laid using the clamping component. The steering assembly controls the direction of movement of the frame, facilitating its movement. The feeding assembly delivers the geotextile, which is guided by the guide component. The clamping component, in conjunction with the geotextile, presses the delivered geotextile firmly against the bottom surface of the trench, ensuring a close fit. Using a laying trolley saves manpower, improves laying accuracy, avoids gaps caused by misalignment between laid geotextiles, and significantly improves laying efficiency.

[0026] Furthermore, the steering component includes a U-shaped frame, a steering rod, and a turntable. The rear wheel is rotatably connected to the U-shaped frame, the bottom of the steering rod is fixedly connected to the U-shaped frame, and the turntable is fixedly connected to the top of the steering rod. The steering rod is rotatably connected to the rear side of the frame, and the turntable controls the steering rod to drive the U-shaped frame and the rear wheel to rotate. By controlling the rotation of the steering rod through the turntable, the rotation of the steering rod drives the U-shaped frame and the rear wheel to rotate, thus realizing the control of the frame's movement direction by driving the rear wheel to rotate through the turntable.

[0027] Furthermore, the feeding assembly includes an adjusting frame, adjusting rods, and support rollers. The adjusting frame is fixedly connected to both sides of the top of the vehicle frame and has adjusting grooves. Adjusting screws are fixedly connected to both ends of the adjusting rods, passing through the adjusting grooves and screwed into adjusting nuts, which are tightened onto the adjusting frame. The support rollers are mounted on the two adjusting rods at both ends, and the geotextile roll is sleeved on the outside of the support rollers. By loosening the adjusting nuts, the adjusting screws at both ends of the adjusting rods move up and down within the adjusting grooves, thereby controlling the adjusting rods to adjust the height of the support rollers. After the height adjustment is complete, the adjusting nuts are tightened for fixation. The geotextile roll has a central shaft hole through which the support roller passes. The support roller is used to mount the geotextile roll, allowing the geotextile roll to rotate around the support roller and feed the geotextile out.

[0028] Furthermore, the guide component includes a guide roller and a lifting rod. The lifting rod is fixedly connected to both sides of the top of the vehicle frame and has an elongated hole. Both ends of the guide roller have connecting rods with external threads. The ends of the connecting rods pass through the elongated holes and are screwed into a fastening nut, which is tightened onto the lifting rod. By loosening or loosening the fastening nut, the connecting rods are controlled to move the guide roller up and down along the elongated holes. The bottom surface of the guide roller rests against the top surface of the geotextile, thus confining the geotextile between the guide roller and the vehicle frame, thereby guiding the transport of the geotextile.

[0029] Furthermore, the clamping component includes a support column, a swing rod, and a clamping roller. The support column is fixedly connected to both ends of the front side of the frame. One end of the swing rod is rotatably connected to the support column, and the clamping roller is rotatably connected to the other end of the swing rod. The support column provides support, and the rotatable connection of one end of the swing rod to the support column causes the swing rod to drive the clamping roller to swing, thus pressing the geotextile onto the foundation trench.

[0030] Furthermore, in step e, each bottom of the grid is provided with a water outlet hole one, and the end of the mounting frame near the limiting seat is provided with a corresponding water outlet hole two. The limiting seat is provided with a through drainage hole corresponding to the water outlet hole two, so that the water in the planting trough can be discharged through the water outlet hole one, the water outlet hole two, and the drainage hole. By setting up the water outlet hole one and the water outlet hole two, and providing a corresponding drainage hole on the limiting seat, when a large amount of water from the river enters the planting trough, the water in the planting trough can be discharged smoothly, avoiding excessive water accumulation and damage to the plants.

[0031] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0032] This invention involves dividing the riverbank revetment into sections for phased construction. First, a retaining wall is erected to separate the river water from the construction section. Then, a foundation trench is excavated and leveled. Next, geotextile is laid on the surface of the trench in sections using a laying trolley. The end of the later-laid geotextile is pressed tightly against the previously laid geotextile to ensure a seamless connection between the geotextile layers. After the geotextile is laid, a layer of sand and gravel is filled in, followed by the installation of a steel mesh and the pouring of a concrete layer to ensure the structural strength of the revetment. A limiting hole is reserved at the end of the revetment closest to the river. The limiting block at the bottom of the limiting seat is inserted into the limiting hole for positioning and installation. Then, the bottom of the installation frame is fixed to the concrete layer. Finally, the grid is installed in the installation frame, dividing the installation frame into several planting troughs for planting greenery.

[0033] In step a of this invention, the specific structure of the retaining wall includes a retaining plate and a connecting rod. Fixed seats are provided on both sides of the foundation trench. One end of the connecting rod is movably connected to the fixed seat, and the retaining plate is lifted and lowered to the other end of the connecting rod. The connecting rod and fixed seats enable the installation of the retaining plate. The connecting rod drives the retaining plate to slide and adjust, facilitating its insertion into the water. This allows the water between the retaining plate and the construction section to be pumped out, thus separating the water from the riverbank.

[0034] In step c of this invention, the laying trolley's specific structure includes a frame, front wheels, and rear wheels. The front wheels are rotatably connected to both ends of the front end of the frame, and the rear wheels are rotatably connected to the rear side of the frame via a steering component. A feeding assembly is connected to the rear side of the top of the frame, and a clamping component is connected to the front side of the top of the frame. A guide component is connected to the top of the frame, located between the clamping component and the feeding assembly. The feeding assembly delivers the wound geotextile, which is then conveyed through the guide component to the front side of the frame. The geotextile is then laid using the clamping component. The steering assembly controls the direction of the frame's movement, facilitating its movement. The feeding assembly delivers the geotextile, which is guided by the guide component. The clamping component, in conjunction with the geotextile, presses the delivered geotextile firmly against the bottom surface of the trench, ensuring a close fit. Using a laying trolley saves manpower, improves laying accuracy, avoids gaps caused by misalignment between laid geotextile sections, and significantly improves laying efficiency.

[0035] In step e of this invention, each bottom of the grid is provided with a water outlet hole 1, and the end of the mounting frame near the limiting seat is provided with a corresponding water outlet hole 2. The limiting seat is provided with a through drainage hole corresponding to the water outlet hole 2, so that water in the planting trough can be discharged through the water outlet hole 1, the water outlet hole 2, and the drainage hole. By setting the water outlet hole 1 and the water outlet hole 2, and providing the corresponding drainage hole on the limiting seat, when a large amount of water from the river enters the planting trough, the water in the planting trough can be discharged smoothly, avoiding excessive water accumulation and damage to the plants.

Detailed Implementation

[0049] As shown in Figures 1 to 11, a construction method for an ecological bank protection system according to the present invention includes the following steps:

[0050] a. Pre-construction preparation

[0051] First, the revetment along the line is divided into sections for construction. Then, a retaining wall 1 is installed on the water-facing side of the revetment. The water is then pumped out, separating the water from the bank using the retaining wall 1. The retaining wall 1 consists of a retaining plate 12 and a connecting rod 13. Fixed seats 14 are installed on both sides of the foundation trench 2. One end of the connecting rod 13 is movably connected to the fixed seat 14, and the retaining plate 12 is lifted and connected to the other end of the connecting rod 13. The connecting rod 13 and the fixed seats 14 allow for the installation of the retaining plate 12. The connecting rod 13 moves the retaining plate 12, allowing it to slide and adjust, facilitating its insertion into the water. The water between the retaining plate 12 and the construction section is then pumped out, effectively separating the water from the bank using the retaining wall 1. The fixed seat 14 has a through hole through which one end of the connecting rod 13 passes. A tightening screw 15 is located at the top of the fixed seat 14, passing through the through hole and tightening onto the connecting rod 13. The through-hole design facilitates the sliding adjustment of the baffle plate 12 by the connecting rod 13. The connecting rod 13 is fixed to the fixing seat 14 by tightening the top screw 15 onto the connecting rod 13. The baffle plate 12 has sliding grooves 16 on both sides, with sliders 17 slidably connected within the grooves 16. A locking screw 18 is provided at the other end of the connecting rod 13, tightened onto the slider 17. An insertion part 19 is provided at the bottom of the baffle plate 12. When the height of the baffle plate 12 needs to be adjusted, the locking screw 18 is loosened, and the slider 17 slides within the groove 16, thereby controlling the raising and lowering of the baffle plate 12. After adjustment, the locking screw 18 is tightened, clamping the connecting rod 13 at both ends of the baffle plate 12, thus fixing the baffle plate 12.

[0052] b. Excavation of foundation trench

[0053] Excavate foundation trench 2 on one side of the revetment. First, excavate to the bedrock, and then use a pickaxe to excavate to the design elevation and cross-section. Pay attention to the protection of the foundation pit during excavation, and use wooden piles for protection if necessary to ensure construction safety.

[0054] c. Foundation trench laying

[0055] (1) Foundation trench leveling

[0056] First, the bottom surface of foundation trench 2 is leveled using a flat roller. Then, new soil is backfilled and compacted. Next, the cleaned masonry stones are laid flat on the bottom surface of foundation trench 2 and laid in layers using the mortar-bedding method. The gaps between the masonry stones are filled with mortar to make the surface smooth.

[0057] (2) Geotextile laying

[0058] Geotextile 3 is laid on the surface of the foundation trench 2 in sections using a laying trolley 48. When laying two adjacent geotextile 3 sections, the corresponding end of the later-laid geotextile 3 is pressed against the previously laid geotextile 3. The specific structure of the laying trolley 48 includes a frame 20, front wheels 21 and rear wheels 22. The front wheels 21 are rotatably connected to both ends of the front end of the frame 20. The rear wheels 22 are rotatably connected to the rear side of the frame 20 through a steering component 23. A feeding component 24 is connected to the rear side of the top of the frame 20. A clamping component 25 is connected to the front side of the top of the frame 20. A guide component 26 is connected to the top of the frame 20. The guide component 26 is located between the clamping component 25 and the feeding component 24. The feeding component 24 delivers the rolled geotextile 3. The geotextile 3 is transported through the guide component 26 to the front side of the frame 20. The geotextile 3 is laid through the clamping component 25. The steering assembly controls the direction of movement of the frame 20, facilitating its movement. The feeding assembly 24 delivers the geotextile 3, guided by the guide component 26. The pressing component 25 presses the delivered geotextile 3 firmly against the bottom of the trench 2, ensuring a snug fit. The use of the laying trolley 48 saves manpower, improves laying accuracy, and prevents gaps caused by misalignment between the laid geotextile 3, significantly increasing laying efficiency. The steering assembly 23 includes a U-shaped frame 28, a steering rod 29, and a turntable 30. The rear wheel 22 is rotatably connected to the U-shaped frame 28. The bottom of the steering rod is fixedly connected to the U-shaped frame 28, and the turntable 30 is fixedly connected to the top of the steering rod. The steering rod 29 is rotatably connected to the rear side of the frame 20. The turntable 30 controls the steering rod 29 to rotate the U-shaped frame 28 and the rear wheel 22. The turntable 30 drives the steering rod 29 to rotate, which in turn drives the U-shaped frame 28 to rotate the rear wheel 22. This achieves the goal of driving the rear wheel 22 to rotate via the turntable 30, and controlling the direction of movement of the frame 20 by driving the rear wheel 22 to rotate. The feeding assembly 24 includes an adjusting frame 31, an adjusting rod 32, and a support roller 33. The adjusting frame 31 is fixedly connected to both sides of the top of the frame 20. The adjusting frame 31 is provided with an adjusting groove 34. Adjusting screws 35 are fixedly connected to both ends of the adjusting rod 32. The adjusting screws 35 pass through the adjusting groove 34 and are screwed into adjusting nuts 36. The adjusting nuts 36 are tightened on the adjusting frame 31. The two ends of the support roller 33 are respectively mounted on the two adjusting rods 32, and the geotextile roll 27 is sleeved on the outside of the support roller 33. By loosening the adjusting nut 36, the adjusting screws 35 at both ends of the adjusting rod 32 move up and down within the adjusting groove 34, thereby controlling the adjusting rod 32 to drive the support roller 33 to adjust its height. After the height adjustment is completed, the adjusting nut 36 is tightened to fix it. The geotextile roll 27 has a shaft hole in the center, through which the support roller 33 passes. The support roller 33 is used to install the geotextile roll 27, so that the geotextile roll 27 rotates around the support roller 33 to deliver the geotextile 3.The guide component 26 includes a guide roller 37 and a lifting rod 38. The lifting rod 38 is fixedly connected to both sides of the top of the frame 20. The lifting rod 38 has an elongated hole 39. Both ends of the guide roller 37 are provided with connecting rods 40. The ends of the connecting rods 40 are provided with external threads and pass through the elongated hole 39. A fastening nut 41 is screwed into the end of the connecting rod 40 and tightened onto the lifting rod 38. By loosening the fastening nut 41, the connecting rod 40 is controlled to drive the guide roller 37 to move up and down along the elongated hole 39. The bottom surface of the guide roller 37 abuts against the top surface of the geotextile 3, so that the geotextile 3 is limited between the guide roller 37 and the frame 20, thereby providing a guiding function for the conveying of the geotextile 3. The clamping component 25 includes a support column 42, a swing rod 43, and a clamping roller 44. The support column 42 is fixedly connected to both ends of the front side of the frame 20. One end of the swing rod 43 is rotatably connected to the support column 42, and the clamping roller 44 is rotatably connected to the other end of the swing rod 43. The support column 42 provides a supporting effect, and the swing rod 43 is rotatably connected to the support column 42, causing the swing rod 43 to drive the clamping roller 44 to swing, thereby pressing the geotextile 3 onto the foundation trench 2.

[0059] (3) Concrete layer pouring

[0060] Now, a layer of sand and gravel is filled on the geotextile 3. After the sand and gravel layer is sprayed with water, a steel mesh 4 is erected, and then a concrete layer 5 is poured.

[0061] d. Installation of the limit seat

[0062] During the pouring of concrete layer 5, a limiting hole 6 is reserved at the installation location of the limiting seat 7 at the end of the foundation trench 2 near the water surface. After the concrete layer 5 is cured, the limiting block 8 of the limiting seat 7 is installed through the limiting hole 6.

[0063] e. Setting up planting troughs

[0064] First, the mounting frame 9 is fixed to the base trench 2 via the limiting seat 7. The bottom of the mounting frame 9 is fixed to the concrete layer 5. Then, a grid 10 is installed inside the mounting frame 9, dividing the area within the mounting frame 9 into several planting troughs 11. Each grid 10 has a drainage hole 45 at its bottom, and a corresponding drainage hole 46 is provided at the end of the mounting frame 9 near the limiting seat 7. The limiting seat 7 has a through drainage hole 47 corresponding to the drainage hole 46, allowing water in the planting trough 11 to drain out through the drainage holes 45, 46, and 47. By setting the drainage holes 45 and 46, and correspondingly setting the drainage hole 47 on the limiting seat 7, when a large amount of water from the river enters the planting trough 11, the water in the planting trough 11 can be drained smoothly, preventing water accumulation and damage to the plants.

[0065] This invention divides the riverbank revetment into sections for construction. First, a retaining wall 1 is set up to separate the river water from the construction section. Then, a foundation trench 2 is excavated and leveled. Next, geotextile 3 is laid on the surface of the foundation trench 2 in sections using a laying trolley 48. The end of the later-laid geotextile 3 is pressed tightly onto the previously laid geotextile 3 to ensure seamless connection between the geotextile 3. After the geotextile 3 is laid, a layer of sand and gravel is filled in. Then, a steel mesh 4 is erected on the sand and gravel layer, and a concrete layer 5 is poured to ensure the structural strength of the revetment. A limiting hole 6 is reserved at the end of the revetment near the river. The limiting block 8 at the bottom of the limiting seat 7 is inserted into the limiting hole 6 for positioning and installation. Then, the bottom of the installation frame 9 is fixed on the concrete layer 5. Finally, the grid 10 is installed in the installation frame 9. The grid 10 divides the installation frame 9 into several planting troughs 11, which are used for planting green plants.

[0066] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
