Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to a greening planting structure for a concrete slope retaining wall. Background Technology

[0002] In the construction of highways, railways, water conservancy and other projects, slope protection is the key to ensuring the safety of the project and the stability of the surrounding ecological environment. Among them, concrete revetment walls are widely used in slope protection projects in mountainous areas or areas with complex geological conditions due to their advantages such as high structural strength, strong erosion resistance and good durability. By working with anchor bolts and other reinforcement components and anchoring them into the slope body, they can effectively resist the sliding and collapse of the slope soil and ensure the long-term structural stability of the project slope.

[0003] However, the construction of concrete revetment walls on slopes in mountainous areas has a significant impact on the ecology and landscape. Specifically, the slopes of mountainous projects are often surrounded by abundant natural vegetation, forming a complete local ecosystem. Concrete revetment walls are rigid and impermeable structures, which not only occupy a large area of ​​the original green vegetation covering the mountain, leading to a decrease in the area's green vegetation coverage, but also create a strong visual contrast with the surrounding lush natural environment due to their monotonous gray-white appearance, thus disrupting the ecological landscape harmony of the slope area.

[0004] To reduce the impact of concrete revetment walls on the ecological environment, ecological slope protection methods such as vegetation covering are commonly used for newly constructed slopes in areas with dense green vegetation. However, for existing concrete revetment wall slopes, directly demolishing the concrete revetment wall and replanting vegetation can damage the original slope reinforcement structure during the demolition process, causing anchor bolts and other components to fail. This can easily lead to slope instability, landslides, and other safety accidents, seriously threatening the safety of the project and the surrounding environment. If simple greening schemes are used, such as surface spraying of vegetated concrete or hanging planting bags, there are also obvious shortcomings: ① Vegetated concrete is greatly affected by the flatness of the concrete surface, resulting in a low vegetation survival rate; ② Planting bags have poor fixing stability and are prone to falling off under the influence of rainwater erosion or strong winds. In addition, slope greening transformation also needs to solve the critical problem of rainwater drainage. If water accumulates in the greening carrier and cannot be drained in time, it will cause the plant roots to rot due to lack of oxygen, directly affecting the survival of the vegetation.

[0005] Therefore, there is an urgent need to design a greening planting structure for the concrete slope retaining wall to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a greening planting structure for concrete slope revetment walls, which is mainly used for greening planting on existing concrete slope revetment walls, so as to achieve greening planting without damaging the original slope, and to ensure the stability of the slope and the safety of the surrounding environment.

[0007] This utility model discloses a greening planting structure for a concrete slope retaining wall, including a concrete slope retaining wall; the upper surface of the concrete slope retaining wall is provided with a planting trough box with a top opening for greening planting, and multiple planting trough boxes are evenly arranged along the inclined direction of the concrete slope retaining wall. The bottom of each planting trough box is provided with a fixing component that can be detachably connected to the concrete slope retaining wall. The concrete slope retaining wall is also provided with receiving grooves corresponding to the fixing components. Each planting trough box is provided with a drainage pipe at one end near the slope foot of the concrete slope retaining wall. Both ends of the drainage pipe penetrate the side wall of the planting trough box and are connected to the outside. Multiple seepage holes connected to the drainage pipe are opened on the pipe section located inside the planting trough box.

[0008] Furthermore, the seepage holes are arranged along the length of the drainage pipe on the side of the drainage pipe away from the planting trough.

[0009] Furthermore, the fixing component includes an insert block that penetrates the bottom of the planting trough and is fixedly connected to it. The lower end of the insert block extends downward and is inserted into the receiving groove. The insert block has an installation cavity inside. The insert block also has a rotating rod that is rotatably connected to it. One end of the rotating rod penetrates the top of the insert block and extends into the planting trough, and is fixedly connected to a handle. The other end of the rotating rod extends into the installation cavity and is rotatably connected to the bottom of the installation cavity. The section of the rotating rod extending into the installation cavity has a threaded section. An internal threaded sleeve that is threadedly connected to the threaded section is fitted on the outer side of the threaded section. At least two symmetrically arranged hinge rods are hinged on the outer side of the internal threaded sleeve. Each hinge rod has a pin hinged at the end away from the internal threaded sleeve. The side wall of the insert block has a through hole for the pin to pass through. The pin is slidably disposed in the through hole. The inner side wall of the receiving groove also has slots that correspond one-to-one with and fit the pins. The pins are inserted into the slots.

[0010] As a preferred embodiment, the bottom of the mounting cavity is provided with a limiting boss for limiting the displacement of the insert post. The side wall of the limiting boss abuts against the side wall of the insert post entering the mounting cavity. The limiting boss is provided with a placement groove for placing the internal threaded sleeve. One end of the rotating rod extending into the mounting cavity is rotatably connected to the placement groove.

[0011] As a preferred embodiment, the bottom of the handle is provided with an annular groove, and a first sealing ring is provided in the annular groove, the bottom of the first sealing ring being sealed and fitted with the top of the insert block.

[0012] As a preferred embodiment, a second sealing ring is fixedly provided on the inner side of the perforation, and the inner wall of the second sealing ring is sealed and fitted to the outer wall of the insert.

[0013] As a preferred embodiment, the first sealing ring and the second sealing ring are rubber sealing rings.

[0014] Furthermore, geotextile is fixedly sleeved on the section of the drainage pipe located inside the planting trough.

[0015] The beneficial effects of this utility model are as follows: the greening planting structure of this slope concrete revetment wall does not require the removal of the original slope concrete revetment wall. It only requires opening a corresponding number of receiving slots on the surface of the existing slope concrete revetment wall, and installing the planting slots on the slope concrete revetment wall through fixing components to achieve greening planting. It completely preserves the reinforcement effect of the slope concrete revetment wall on the slope. By filling the planting slots with planting soil and planting plants, the green vegetation coverage of the slope area can be restored, making up for the damage to the ecological landscape caused by the slope concrete revetment wall, and has good stability. In addition, the planting slots are set along the inclined direction of the slope concrete revetment wall, and a drainage pipe with seepage holes is set at the end of the planting slots near the slope toe of the slope concrete revetment wall, which can drain excess rainwater in the planting slots in time, avoid rainwater retention leading to plant root rot, and ensure the survival rate of vegetation.

Detailed Implementation

[0022] The present invention will be further described below.

[0023] This utility model provides a greening planting structure for a concrete slope retaining wall, mainly used for greening planting on existing concrete slope retaining walls. It includes a concrete slope retaining wall 1; the upper surface of the concrete slope retaining wall 1 is provided with a planting trough 2 with a top opening for greening planting; multiple planting troughs 2 are evenly arranged along the inclined direction of the concrete slope retaining wall 1; the bottom of each planting trough 2 is provided with a fixing component 4 that is detachably connected to the concrete slope retaining wall 1; the concrete slope retaining wall 1 is also provided with receiving grooves 11 corresponding to the fixing components 4; each planting trough 2 is provided with a drainage pipe 3 at one end near the slope foot of the concrete slope retaining wall 1; both ends of the drainage pipe 3 penetrate the side wall of the planting trough 2 and are connected to the outside; multiple seepage holes 31 connected to the drainage pipe 3 are opened on the pipe section inside the planting trough 2.

[0024] like Figures 1-5As shown, the greening structure of the slope concrete revetment wall includes a slope concrete revetment wall 1, which is a pre-constructed concrete revetment wall. Planting troughs 2 are installed on the upper surface of the slope concrete revetment wall 1, and these troughs 2 are evenly distributed along the inclined direction of the slope concrete revetment wall 1, enabling batch greening and ensuring the uniformity and aesthetics of the slope greening. The top opening of the planting troughs 2 facilitates the filling of planting soil and the planting of plants. To ensure the connection stability between the planting troughs 2 and the slope concrete revetment wall 1, a fixing component 4 is provided at the bottom of the planting troughs 2. A receiving groove 11 corresponding to the fixing component 4 is opened on the upper part. The fixing component 4 is detachably installed in the receiving groove 11 to ensure that the planting trough box 2 is stably installed on the slope concrete revetment wall 1. In order to ensure the connection stability between the planting trough box 2 and the slope concrete revetment wall 1, multiple fixing components 4 can be set at the bottom of the planting trough box 2 to enhance its connection stability with the slope concrete revetment wall 1. The fixing components 4 can be directly nailed to the slope concrete revetment wall 1 using existing expansion bolts, pins, etc. The fixing components 4 are detachably connected to the slope concrete revetment wall 1, and can be replaced and maintained according to the usage of the planting trough box 2. A drainage pipe 3 is also provided at the end of the planting trough 2 near the toe of the concrete retaining wall 1. The two ends of the drainage pipe 3 pass through the side wall of the planting trough 2 and are connected to the outside to ensure a stable connection between the drainage pipe 3 and the planting trough 2 and to ensure that the drainage pipe 3 is firmly fixed. Multiple seepage holes 31 connected to the drainage pipe 3 are opened on the pipe section of the drainage pipe 3 located in the planting trough 2. Because the planting trough 2 is set along the inclined direction of the concrete retaining wall 1 and the drainage pipe 3 is set on the side of the planting trough 2 near the toe of the concrete retaining wall 1, excess rainwater in the planting trough 2 will flow downward due to gravity and seep into the drainage pipe 3 through the seepage holes 31 opened on the drainage pipe 3. The excess rainwater in the planting trough 2 is discharged to the outside of the planting trough 2 through the drainage pipe 3, so as to avoid rainwater retention and root rot of plants and ensure the survival rate of vegetation. The greening planting structure of this slope concrete revetment wall does not require the removal of the original slope concrete revetment wall 1. It only requires opening a corresponding number of receiving slots 11 on the surface of the existing slope concrete revetment wall 1, and installing the planting slot boxes 2 on the slope concrete revetment wall 1 through the fixing components 4 to achieve greening planting. It completely preserves the slope reinforcement function of the slope concrete revetment wall 1. By filling the planting slot boxes 2 with planting soil and planting plants, the green vegetation coverage of the slope area can be restored, making up for the damage to the ecological landscape caused by the slope concrete revetment wall 1, and has good stability. Moreover, the planting slot boxes 2 are set along the inclined direction of the slope concrete revetment wall 1, and a drainage pipe 3 with seepage holes 31 is set at the end of the planting slot box 2 near the slope foot of the slope concrete revetment wall 1, which can drain excess rainwater in the planting slot box 2 in time, avoid rainwater retention and root rot of plants, and ensure the survival rate of vegetation.

[0025] To ensure the efficient collection of rainwater from drainage pipe 3 into planting trough 2, such as Figure 2 , Figure 5 As shown, the seepage holes 31 are arranged along the length of the drainage pipe 3 on the side of the drainage pipe 3 away from the planting trough 2. By opening the seepage holes 31 on the side of the drainage pipe 3 away from the planting trough 2, that is, setting the seepage holes 31 on the side of the drainage hole away from the slope foot of the concrete retaining wall 1, the drainage path is consistent with the natural drainage direction of the slope, optimizing the drainage path, increasing the contact area between the seepage holes 31 and the soil in the planting trough 2, and collecting as much rainwater as possible in the planting trough 2 into the drainage pipe 3 for drainage, avoiding rainwater retention that could cause plant root rot, and ensuring the survival rate of vegetation.

[0026] To ensure the stability of the connection between the fixing component 4 and the receiving groove 11, and to ensure that the planting trough box 2 does not shift after being installed on the concrete retaining wall 1 of the slope, such as Figure 4As shown, the fixing component 4 includes an insert block 41 that penetrates the bottom of the planting trough box 2 and is fixedly connected to the planting trough box 2. The lower end of the insert block 41 extends downward and is inserted into the receiving groove 11. The insert block 41 has an installation cavity 411 inside. The insert block 41 also has a rotating rod 42 that is rotatably connected to the insert block 41. One end of the rotating rod 42 penetrates the top of the insert block 41 and extends into the planting trough box 2 and is fixedly connected to a handle 43. The other end of the rotating rod 42 extends into the installation cavity 411 and is rotatably connected to the bottom of the installation cavity 411. A section of the rotating rod 42 extending into the installation cavity 411 is provided with... The device has a threaded section 421, and an internal threaded sleeve 422 is fitted on the outer side of the threaded section 421 and threadedly connected to the threaded section 421. At least two symmetrically arranged hinge rods 44 are hinged on the outer side of the internal threaded sleeve 422. Each hinge rod 44 has a pin 45 hinged at the end away from the internal threaded sleeve 422. The side wall of the insertion block 41 has a through hole 412 for the pin 45 to pass through. The pin 45 is slidably disposed in the through hole 412. The inner side wall of the receiving groove 11 also has a slot 12 that corresponds to and fits the pin 45 one by one. The pin 45 is inserted into the slot 12. The aforementioned insert 41 penetrates the bottom of the planting trough box 2 and extends downwards to facilitate insertion into the matching receiving groove 11. The receiving groove 11 provides initial fixation and restriction of the insert 41, thus achieving the initial connection between the fixing assembly 4 and the slope concrete revetment wall 1. The insert 41 has an internal mounting cavity 411, which provides installation space for components such as the rotating rod 42, the internal threaded sleeve 422, the hinge rod 44, and the insert post 45. One end of the rotating rod 42 penetrates the top of the insert 41 and extends into the planting trough box 2, while the other end extends into the mounting cavity 411. It is rotatably connected to the bottom of the mounting cavity 411. One end of the rotating rod 42 that extends into the mounting cavity 411 is provided with a threaded section 421. An inner threaded sleeve 422 is fitted on the threaded section 421. By rotating the rotating rod 42, the inner threaded sleeve 422 can be moved up and down. To facilitate the operator to rotate the rotating rod 42 to move the inner threaded sleeve 422 up and down, the end of the rotating rod 42 that extends into the planting trough box 2 is also connected to a handle 43. The handle 43 can also seal the gap between the rotating rod and the insert 41 to prevent rainwater or mud from seeping into the mounting cavity 411 of the insert 41. A hinge rod 44 is hinged to the outer side of the internal threaded sleeve 422, and a pin 45 is hinged to the other end of the hinge rod 44. The hinge rod 44 converts the up-and-down movement of the internal threaded sleeve 422 into the lateral movement of the pin 45, thereby enabling the hinge rod 44 to drive the pin 45 to slide within the through hole 412, so as to move the pin 45 laterally into the slot 12. The pin 45 is inserted into the slot 12 to further enhance the connection stability between the fixing component 4 and the receiving groove 11, and to prevent the fixing component 4 from deforming or shifting during the use of the planting trough box 2, which would cause the connection between the planting trough box 2 and the slope concrete revetment wall 1 to become unstable.Specifically, rotating the rotating rod 42 causes the threaded section 421 and the inner threaded sleeve 422 to rotate, which in turn causes the inner threaded sleeve 422 to move downward. The inner threaded sleeve 422 then causes the hinge rod 44 to move downward, and the hinge rod 44 causes the insert 45 to move outward toward the insert block 41 until the insert block 41 is inserted into the slot 12. The hinge rod 44 is then adjusted from an inclined state to a horizontal state, at which point the position of the insert block 41 is fixed, thereby fixing the position of the planting trough box 2. When it is necessary to replace or repair the planting trough box 2, rotating the rotating rod 42 causes the threaded section 421 to rotate, which in turn causes the inner threaded sleeve 422 to move upward. The inner threaded sleeve 422 then causes the hinge rod 44 to move upward, and the hinge rod 44 causes the insert 45 to move inward toward the insert block 41 until the insert block 41 is removed from the slot 12. The hinge rod 44 is then adjusted from a horizontal state to an inclined state, at which point the insert block 41 is movably positioned in the receiving groove 11, and the planting trough box 2 can be moved. Furthermore, the insert 41, handle 43, rotating rod 42, insert post 45, hinge rod 44, and internal threaded sleeve 422 in the fixing assembly 4 can all be made of stainless steel.

[0027] As a preferred method, to prevent the insert 45 from detaching from the through hole 412 and completely entering the mounting cavity 411 when it moves into the mounting slot along with the hinged post, making it inconvenient to use the hinged rod 44 to drive the insert 45 into the slot 12 for fixing, such as Figure 4 As shown, the bottom of the mounting cavity 411 is provided with a limiting boss 413 for limiting the displacement of the insertion post 45. The side wall of the limiting boss 413 abuts against the side wall of the insertion post 45 entering the mounting cavity 411. The limiting boss 413 is provided with a placement groove 414 for placing the internal threaded sleeve 422. One end of the rotating rod 42 extending into the mounting cavity 411 is rotatably connected to the placement groove 414. By providing a limiting boss 413 at the bottom of the mounting cavity 411, and utilizing the abutment between the side wall of the limiting boss 413 and the side wall of the insertion post 45 entering the mounting cavity 411, the distance of the insertion post 45 entering the mounting cavity 411 is controlled, ensuring that the insertion post 45... It will not detach from the perforation 412 and fully enter the mounting cavity 411; furthermore, in order to prevent the operator from rotating the rotating rod 42 too much, causing the internal threaded sleeve 422 to move down too much, resulting in the insert 41 extending into the slot 12 and connecting with the slot 12, while the internal threaded sleeve 422 is still downward, causing damage to the hinge rod 44, the limiting boss 413 is provided with a placement groove 414 for placing the internal threaded sleeve 422. The downward movement distance of the internal threaded sleeve 422 is controlled by the placement groove 414, ensuring that when the insert 45 extends into the slot 12 and the hinge rod 44 remains horizontal, the operator cannot drive the internal threaded sleeve 422 to move down by rotating the rotating rod 42.

[0028] To prevent rainwater or muddy water from seeping into the mounting cavity 411 through the gap between the rotating handle 43 and the insert 41, which could damage the components inside the mounting cavity 411 due to rainwater immersion, such as... Figure 4As shown, an annular groove 431 is provided at the bottom of the rotating handle 43, and a first sealing ring 432 is provided in the annular groove 431. The bottom of the first sealing ring 432 is sealed and fitted with the top of the insert block 41. By providing an annular groove 431 at the bottom of the rotating handle 43 and providing a first sealing ring 432 in the annular groove 431, the sealing and fitting of the first sealing ring 432 with the top of the insert block 41 can effectively prevent rainwater and mud water in the planting trough box 2 from seeping into the installation cavity 411 through the gap between the rotating handle 43 and the insert block 41. This ensures a dry operating environment in the installation cavity 411 and prevents metal parts such as the threaded section 421 and the internal threaded sleeve 422 in the installation cavity 411 from being damaged by rainwater immersion, thus extending the service life of the fixing component 4.

[0029] To prevent water from seeping into the receiving groove 11 along its edge from entering the receiving groove 11 through the gap between the perforation 412 and the insertion post 45 into the mounting cavity 411, such as... Figure 4 As shown, a second sealing ring 4121 is fixedly provided inside the perforation 412, and the inner wall of the second sealing ring 4121 is sealed and fitted to the outer wall of the insertion post 45. By providing a second sealing ring 4121 that is sealed and fitted to the insertion post 45 inside the perforation 412, rainwater and mud are prevented from seeping into the installation cavity 411 through the gap between the insertion post 45 and the perforation 412, thereby further enhancing the sealing performance of the fixing assembly 4 and ensuring the safe use of each component of the fixing assembly 4.

[0030] To ensure the sealing effect of the first sealing ring 432 and the second sealing ring 4121, the first sealing ring 432 and the second sealing ring 4121 are rubber sealing rings. Rubber has good elasticity and sealing properties, and can fit tightly to the contact surface. Even if slight wear occurs during long-term use, it can maintain the sealing effect by its own elasticity. At the same time, the rubber material has good aging resistance and corrosion resistance, and can be used for a long time.

[0031] To prevent rainwater from seeping into the drainage pipe 3 through the seepage hole 31 and bringing soil from the planting trough 2 into the drainage pipe 3, thus avoiding blockage of the seepage hole 31, such as... Figure 5 As shown, a geotextile 32 is fixedly sleeved on the section of the drainage pipe 3 located inside the planting trough 2. The geotextile 32 has good filtration performance, which can effectively prevent the planting soil in the planting trough 2 from flowing into the drainage pipe 3 with rainwater, preventing the planting soil from clogging the seepage holes 31 and the drainage pipe 3, ensuring unobstructed drainage channels and stable drainage function. At the same time, the geotextile 32 has water permeability, which will not prevent rainwater from entering the drainage pipe 3 through the drainage holes, thus ensuring the drainage effect and retaining the planting soil in the planting trough 2, avoiding soil loss and affecting plant growth.

[0032] The working principle of the greening planting structure for the concrete slope protection wall provided by this utility model is as follows:

[0033] A drainage ditch is constructed at the toe of the slope. Receiving grooves 11 and slots 12 are made on the upper surface of the existing concrete retaining wall 1 according to the installation position of the fixing component 4. After the receiving grooves 11 and slots 12 are constructed, planting trough boxes 2 are placed accordingly, and the inserts 41 of the fixing component 4 are inserted into the corresponding receiving grooves 11. Then, the handle 43 is rotated using a tool, causing the rotating rod 42 to rotate. With the threaded section 421 of the rotating rod 42 and the internal threaded sleeve 422 threaded together, the rotating rod 42 rotates, causing the internal threaded sleeve 422 to move downwards. This, in turn, causes the hinge rod 44 to move. The hinge rod 44 then causes the insert 45 to move outwards from the insert 41 until the insert 41 is inserted into the slot 12. The hinge rod 44 is then adjusted from an inclined state to a horizontal state (e.g., ...). Figure 4 As shown), after the insert 41 is inserted into the slot 12, the position of the insert 41 is fixed, thereby fixing the position of the planting trough 2. The corresponding number of planting troughs 2 are installed according to the area of ​​the slope concrete revetment wall 1. Then, the planting trough 2 is filled with planting soil, and plants are planted in the planting soil. In this way, green plants are planted on the slope concrete revetment wall 1, and the green plants are restored. The end of the drainage pipe 3 extending outside the planting trough 2 is connected to the pipe through the pipe joint, and the bottom end of the connected pipe is introduced into the drainage ditch opened at the foot of the slope. If there is a lot of rainwater in the planting trough 2, it is blocked by the geotextile 32 to prevent the soil in the planting trough 2 from flowing into the drainage pipe 3 with the rainwater and being discharged. The excess rainwater is filtered through the geotextile 32 and flows into the drainage pipe 3 through the drainage hole, and is introduced into the drainage ditch at the foot of the slope through the external pipe and discharged away.
