Description

Technical Field

[0001] The present application belongs to the field of rock slope protection, and specifically relates to a greening slope protection structure and method suitable for rock slopes. Background Art

[0002] Rock slope refers to a slope composed of rocks. Ecological restoration of rock slopes first requires the construction of a soil environment necessary for plant growth. However, the mechanical properties of rock mass and plant slope protection soil are significantly different. Taking limestone slopes as an example, the elastic modulus of limestone at different weathering degrees is 10GPa-50GPa, while the elastic modulus of the root-soil complex is only 3MPa-10MPa. It is difficult for the slope protection soil and the rock slope to form a unified whole, and the "two-skin" phenomenon is very likely to occur. The contact surface between the root-soil complex formed in the plant slope protection and the rock becomes a weak sliding zone. Under the action of rainfall, the shear strength of the slope protection soil decreases, and the soil is prone to sliding and instability along the contact surface between the soil and the rock, posing a serious potential threat to the safety of the slope foot. In order to protect the slope from erosion and collapse, slope protection is usually carried out.

[0003] Among the rock slope protection measures, greening and slope protection is carried out by planting vegetation. The root system of the planted plants can firmly fix the soil, effectively prevent soil erosion, and provide a beautification effect when protecting the slope. However, in the dry season, long-term high-intensity sunshine causes the slope protection vegetation to lack water, affecting the normal survival and growth of the vegetation, and it is easy to die when the water shortage is serious. Therefore, manual watering is required to replenish water for the plants, which is labor-intensive, inconvenient to operate, and has high labor costs.

[0004] Since slope protection plants can intercept rain and resist slope scour, they reduce the channels for rainfall to infiltrate the slope, and can absorb water inside the slope through plant transpiration, which plays a positive role in maintaining the stability of rock slopes. Therefore, plant slope protection has become an important part of the treatment of exposed rock slopes, and the development of plant slope protection technology is of great significance to the treatment of rock slope projects. Summary of the invention

[0005] The present application provides a greening slope protection structure and method suitable for rock slopes, which solves the problem that the slope protection vegetation of rock slopes in the dry season has a low survival rate and is easy to die, resulting in poor protection effect.

[0017] The control module, when it is determined that the conditions for activating the second water replenishment component are met, issues a control instruction to activate the solar follower so that the convex lens focuses the light on the water tank.

[0025] Preferably, the inner wall of the internal water conduit is provided with a water absorbing member and the tube wall of the internal water conduit is provided with a plurality of water holes.

[0026] The present application also includes a greening slope protection method, which is applied to the above-mentioned control system, and the method includes: determining whether the vegetation is in a water shortage state, and if so, determining whether the second water replenishment component meets the activation condition, wherein determining whether the vegetation is in a water shortage state includes:

[0027] Determining whether the soil moisture in the planting area is lower than a preset soil moisture, and if so, determining that the vegetation is in a water shortage state;

[0028] If the vegetation is in a water shortage state, it is determined whether the activation condition of the second water replenishment component is met, wherein the activation condition includes: determining whether the liquid level in the first water reservoir is lower than a preset liquid level, and if so, activating the second water replenishment component.

[0029] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0030] (1) By setting up planting hangers on rock slopes, and setting up water storage areas and planting areas in the planting hangers, and connecting the water storage areas and planting areas with internal and external water pipes, water is provided to the vegetation in the planting area during the dry season, and the water in the water storage area is introduced into the planting area, thereby ensuring that the vegetation will not die during the dry season, eliminating or reducing the number of artificial watering. The vegetation can use the water resources in the water storage area to survive and grow during the dry season, thereby ensuring the greening slope protection effect on the rock slope during the dry season.

[0031] By setting a first water reservoir below the planting area, the excess water in the planting hanger in the rainy season naturally sinks in the planting area and accumulates in the first water reservoir. In the dry season, the rainwater accumulated in the planting hanger is guided to the planting area through the internal water pipe through the first water replenishment component connecting the first water reservoir and the planting area, so as to provide water replenishment for the vegetation.

[0032] The second water reservoir at the bottom accumulates precipitation in the rainy season, and in the dry season, the rainwater accumulated outside is guided into the planting area through the external water pipe by connecting the second water reservoir with the second water replenishment component in the planting area, so as to provide water replenishment for the vegetation;

[0033] The first water replenishment component and the second water replenishment component, on the one hand, replenish water from the inside of the planting hanger, and from the roots of the vegetation upwards, and on the other hand, replenish water from the outside of the planting hanger, and from the exposed surface of the vegetation downwards. The two work together to achieve effective water replenishment for vegetation in the dry season, reduce the frequency of artificial watering, and avoid the need for artificial drainage during the rainy season to avoid excessive water accumulation in the planting hanger that affects plant growth.

[0034] (2) This solution sets a heating component and uses the convex lens to focus on the water tank to heat the water in the water tank for a long time, so that it generates water vapor and rises along the external water pipe to the planting hanger for water replenishment. In the prior art, water pipes and water pumps are set up, and water is pumped from the outside to replenish water to the planting hanger in the dry season. However, the working environment in the rocky slope area is poor, and it is inconvenient to power on the water pump. In addition, this method requires manual control of the water pump to pump water to replenish water to the vegetation. The special environment of the rocky slope is not convenient for manual pumping operations. This method is difficult to operate and has safety hazards. This solution collects rainwater in the rainy season by setting up a second water reservoir. When the amount of collected rainwater is large, the liquid level in the second water reservoir reaches the height of the bottom of the water tank, and enters the water tank through the water inlet at the bottom of the water tank. In the dry season, the temperature is high and the sunlight time is long. The water in the water tank is heated in combination with a convex lens to generate water vapor. Since a tank cover is provided on the top of the water tank, the water vapor can be prevented from evaporating directly into the air. The water vapor rises along the air guide section, condenses into liquid in the condensation section, and drips into the planting area, providing water replenishment for the vegetation in the dry season.

[0035] (3) The heating component in this scheme uses ambient sunlight to focus the water in the second water tank through a convex lens to heat it and then evaporate water vapor. The water vapor diffuses upward and goes up along the external water pipe to the condensation section. There is no insulation layer, so the water vapor condenses into droplets and drips into the planting area through the downspout. The condensed water vapor is used to replenish water, which can avoid the impact of rain acidity on plant growth. The water in the second water reservoir is focused and heated by a convex lens, and then water vapor rises. The water vapor diffuses upward, and after ascending to the condensation section along the external water pipe, there is no insulation layer, so that the water vapor condenses into droplets, which drip into the planting area through the downspout. The water vapor condensation is used for water replenishment, which can avoid the influence of rain acidity on plant growth. There is no need to set up a water replenishment pool. In the dry season, water is first added to the water replenishment pool, and then the water in the water replenishment pool is led to the planting area through a water pump and a water pipe for vegetation replenishment. The collected rainwater is utilized by utilizing the characteristics of strong ambient light and long sunshine time in the dry season. After being focused and heated by the convex lens for a long time, the rising water vapor is condensed into liquid water to achieve vegetation replenishment, thereby avoiding the complex operation of manual water addition and manual control of water pumping, reducing labor costs, and avoiding the danger of manual water replenishment operations in rock slope areas.

[0036] (4) A control system is set up to control the second water replenishment component to replenish water for the vegetation. When it rains, the second water reservoir will collect rainwater. During the short interval between rainfall and rain, the soil moisture in the planting area is relatively high and the vegetation does not need to be replenished with water. However, when it is sunny, the convex lens will act on the water tank to heat up the water in the water tank. In addition, the water in the water tank that has just experienced rainfall is sufficient, and unnecessary water replenishment will be provided to the vegetation through the second water replenishment component. Therefore, a control system is set up to monitor the soil moisture in the planting area and the liquid level of the first water reservoir. If the soil moisture reaches or exceeds the preset value, it is determined that the vegetation is not in a water shortage state and the second water replenishment component is not activated. If the soil moisture is lower than the preset value, but the liquid level in the first water reservoir is higher than the preset value, the vegetation is replenished only through the first water reservoir and the first water replenishment component, and the water in the second water reservoir and the water tank is retained. On the one hand, excessive water replenishment of the vegetation is avoided, and on the other hand, excessive consumption of water in the first water reservoir and the second water reservoir is avoided at the same time, resulting in an inability to provide water replenishment in the future.

[0037] The activation of the second water replenishment component is achieved by activating the solar follower. When the solar follower is activated, it drives the convex lens connected to it to follow the rotation, so that the convex lens can continue to focus light on the water tank when the sun's position is different, so that the water in the water tank continues to heat up, and then generates water vapor that moves along the external water pipe to replenish water for the vegetation.

[0038] (5) By setting up transverse water pipes and vertical water pipes, the water in the reservoir can be quickly circulated and directed in different directions, which is beneficial to improving the water replenishment efficiency of the vegetation in the planting area. The transverse water pipe connects the two vertical water pipes, which is beneficial to transfer the water in the vertical water pipe to the soil layer in the planting area with the help of the transverse water pipe, and is beneficial to increase the coverage area of ​​the internal water pipe in the planting area, providing rapid and uniform water replenishment for the planting area.

[0039] (6) A water absorbing member is arranged on the inner wall of the internal water pipe, and water is transferred to the planting area through the water holes of the internal water pipe. Since the water storage area is below the planting area, excess precipitation in the rainy season will be stored in the water storage area. In the dry season, the water in the water storage area is transported to the planting area through the water holes through the internal water pipe, ensuring that the vegetation in the planting area will not die in the dry season, without the need for artificial watering, and allowing the vegetation to grow normally, thereby achieving a protective effect on the rock slope.

[0040] The internal water pipe is provided with a plurality of water holes. The water in the first water reservoir enters the internal water pipe through the water holes, and the water in the internal water pipe in the planting area is discharged to the soil layer in the planting area through the water holes, so as to replenish water in the planting area during the dry season, provide the vegetation with the water needed for survival, prevent the vegetation from withering, and avoid or reduce the number of manual watering. In addition, the water holes are conducive to improving the water conduction efficiency of the internal water pipe, quickly replenishing water for the planting area, and when a water hole is blocked, it will not affect the water delivery effect of the internal water pipe, thereby improving the fault tolerance of the structure.

[0041] (7) The method in the present application determines whether to activate the second water replenishment component to replenish water to the vegetation by judging the soil moisture and the liquid level of the first water reservoir, wherein the soil moisture in the planting area is monitored and the monitored soil moisture data is compared with the preset data to determine whether the current soil moisture can meet the survival needs of the vegetation. If the preset humidity is not reached, the vegetation is determined to be in a water shortage state. This method requires the installation of a humidity sensor in the planting area for monitoring. The required structural components are simple and easy to set up, and the setting of the preset soil humidity can be obtained according to the type of vegetation planted and the growth law of the vegetation. If the preset soil humidity can be reached, regardless of whether the liquid level in the first water reservoir is lower than the preset liquid level, there is no need to activate the second water replenishment component, thereby achieving water replenishment when the vegetation needs it, and is conducive to retaining and storing the water in the second water reservoir and the water tank for backup.

[0042] In addition, in the present method, the liquid level in the first water reservoir is monitored, and the monitored liquid level data is compared with the preset liquid level. In the method, the second water replenishment component is activated only when the soil moisture is lower than the preset soil moisture and the liquid level in the first water reservoir is lower than the preset liquid level. If the soil moisture is lower than the preset soil moisture, but the liquid level in the first water reservoir reaches or exceeds the preset liquid level, the vegetation can be replenished with water only through the first water replenishment component, and the water in the second water reservoir can be retained. A liquid level sensor is set in the first water reservoir. This structure is easy to install and implement, and the selection of the preset liquid level can be set according to the height of the internal water pipe in the first water reservoir, that is, by judging whether the internal water pipe can draw water from the first water reservoir to determine whether the preset liquid level is reached, it can be relatively simple to determine whether the internal water pipe can transport water to the vegetation.

[0058] like Figures 1 to 7 As shown, the present application scheme provides a greening slope protection structure suitable for rock slopes, and the greening slope protection structure includes:

[0059] A planting hanger 3, which is fixed to the rock slope 1 by an anchor rod 2, and has a planting area 8 for planting vegetation 4 inside;

[0060] A water storage area, the water storage area includes a first water storage tank 7 located in the planting hanger 3 and a second water storage tank 12 located at the bottom of the rock slope 1, and the first water storage tank 7 is located below the planting area 8;

[0061] The water replenishment component includes a first water replenishment component connecting the first water reservoir 7 and the planting area 8 and a second water replenishment component connecting the second water reservoir 12 and the planting area 8. The first water replenishment component includes an internal water pipe, and the second water replenishment component includes an external water pipe 13. The water in the first water reservoir 7 and the second water reservoir 12 is introduced into the planting area 8 through the internal water pipe and the external water pipe 13.

[0062] By setting a planting hanger 3 on the rock slope 1, and setting a water storage area and a planting area 8 in the planting hanger 3, and connecting the internal water pipe and the external water pipe 13 of the water storage area and the planting area 8, the vegetation 4 in the planting area 8 is provided with water in the dry season, and the water in the water storage area is introduced into the planting area 8, thereby ensuring that the vegetation 4 will not wither in the dry season, eliminating or reducing the number of artificial watering, and the vegetation 4 can use the water resources in the water storage area to survive and grow in the dry season, thereby ensuring the greening slope protection effect of the rock slope 1 in the dry season.

[0063] By setting a first water reservoir 7 below the planting area 8, the excess water in the planting hanger 3 in the rainy season naturally sinks in the planting area 8 and accumulates in the first water reservoir 7. In the dry season, the rainwater accumulated in the planting hanger 3 is guided to the planting area 8 through the internal water pipe through the first water replenishment component connecting the first water reservoir 7 and the planting area 8, so as to provide water replenishment for the vegetation 4.

[0064] The second water reservoir 12 at the bottom is used to accumulate precipitation in the rainy season. In the dry season, the rainwater accumulated outside is guided into the planting area 8 through the external water pipe 13 through the second water supply component connecting the second water reservoir 12 and the planting area 8, so as to provide water supply for the vegetation 4.

[0065] The first water replenishment component and the second water replenishment component, on the one hand, replenish water from the inside of the planting hanger 3, and from the roots of the vegetation 4 upwards, and on the other hand, replenish water from the outside of the planting hanger 3, and from the exposed surface of the vegetation 4 downwards. The two cooperate to achieve effective water replenishment for the vegetation 4 in the dry season, reduce the frequency of artificial watering, and avoid the need for artificial drainage during the rainy season to avoid the problem of excessive water accumulation in the planting hanger 3 affecting plant growth.

[0066] In one embodiment, if Figures 3 to 5 As shown, the second water replenishment component also includes a heating component, which includes a convex lens 15 located on one side of the second water reservoir 12, a solar follower is fixedly provided at the bottom of the convex lens 15, a water tank 14 is provided in the second water reservoir 12, and the convex lens 15 focuses light on the water tank 14.

[0067] Rainwater is collected by the second water reservoir 12 in the rainy season. When the amount of collected rainwater is large, when the liquid level in the second water reservoir 12 reaches the bottom height of the water tank 14, it enters the water tank 14 through the water inlet 141. In the dry season, the temperature is high and the sunlight time is long. The convex lens 15 is used to heat the water in the water tank 14 to generate water vapor, which rises along the external water pipe 13 to the planting hanger to realize the upward transportation of the water in the water tank.

[0068] Preferably, a water inlet 141 communicating with the second water reservoir 12 is provided at the bottom of the water tank 14, a box cover is provided at the top of the water tank 14, and a gas outlet hole communicating with the external water pipe 13 is provided at the box cover. The external water pipe 13 includes an air guide section 131 provided with a heat preservation layer 133 and a condensation section 132 provided with a water outlet 134 along the axial direction, and the gas outlet hole communicates with the end of the air guide section 131.

[0069] In the prior art, water pipes and water pumps are set up, and water is pumped from the outside to replenish water to the planting hanger 3 in the dry season. However, the working environment in the rock slope 1 area is poor, and it is inconvenient to power on the water pump. In addition, this method requires manual control of the water pump to pump water to replenish water to the vegetation 4. The environmental particularity of the rock slope 1 is not convenient for manual pumping operations. This method is difficult to operate and has safety hazards. In this solution, a heating component is set up, and the water in the second water reservoir 12 is focused and heated by the convex lens 15 using ambient sunlight. The water vapor rises, and the water vapor diffuses upward. After ascending along the external water pipe 13 to the condensation section 132, there is no insulation layer 133, so that the water vapor condenses into droplets, which drip into the planting area 8 through the downspout 134, and the water vapor condensation is used to replenish water, which can avoid the impact of rain acidity on plant growth.

[0070] Since a box cover is provided on the top of the water tank 14 to prevent water vapor from evaporating directly into the air, the box cover can be made of transparent acrylic material. The water vapor rises along the air guide section 131, condenses into liquid when it reaches the condensation section 132, and drips into the planting area 8, providing water for the vegetation 4 in the dry season.

[0071] There is no need to set up a water replenishment pool. In the dry season, water is first added to the water replenishment pool, and then the water in the water replenishment pool is led to the planting area 8 through a water pump and a water pipe to replenish the vegetation 4. The collected rainwater is utilized and the characteristics of strong ambient light and long sunshine time in the dry season are utilized. After being focused and heated for a long time by the convex lens 15, the rising water vapor is condensed into liquid water to replenish the vegetation 4, avoiding the complex operations of manual water addition and manual control of water pumps to pump water, reducing labor costs, and avoiding the danger of manual water replenishment operations in the rock slope 1 area.

[0072] Furthermore, in one embodiment, the air guide section 131 of the external water guide pipe 13 is sealed and connected to the box cover at one end, and is integrally connected to the condensation section 132 at the other end. The condensation section 132 is formed by extending the air guide section 131, and a plurality of water outlets 134 are arranged on the side close to the planting hanger 3. After the water vapor condenses in the condensation section 132, it falls into the planting hanger 3 through the water outlets 134 under the action of gravity. In this embodiment, a plurality of retaining ribs 135 are arranged on the inner wall of the condensation section 132 of the pipeline to prevent the condensed water from flowing back.

[0073] In this method, a heating component is set up to focus the water in the second water tank 12 through a convex lens 15 to heat it up and then evaporate the water vapor. The water vapor diffuses upward and goes up along the external water pipe 13 to the condensation section 132. The absence of the insulation layer 133 causes the water vapor to condense into droplets, which drip into the planting area 8 through the downspout 134. The condensed water vapor is used for water replenishment, which can avoid the impact of the acidity of rainwater on plant growth.

[0074] like Figure 4As shown, the inner wall of the condensation section 132 can be formed into an annular concave or annular convex to form a retaining rib 135, and the water vapor slides along the concave area or the convex area to the water outlet 134 after condensation, so as to prevent the condensed water droplets from flowing back. Preferably, the concave area and the convex area are concave or convex toward the direction of the air guide section 131 to enhance the blocking effect of the water droplet backflow and prevent the condensed water from flowing back.

[0075] Alternatively, the condensation section 132 is bent toward the planting hanger 3 compared to the air guide section 131, and the bent end opening forms a drain. After the water vapor condenses, it passes through the bent condensation section 132 to have a diversion effect, so that the water flows along the inner wall of the condensation section 132 to the drain port 134 and falls to the planting hanger 3.

[0076] Furthermore, a seal is provided between the cover and the body of the water tank 14, or the cover and the body of the water tank 14 are an integrated structure to prevent the water vapor generated after heating from escaping and reduce the heat dissipation of the water tank 14. At least the cover of the water tank 14 is made of transparent material, and preferably, the entire water tank 14 is made of transparent material to ensure that the light is focused on the water tank 14 to heat the water inside.

[0077] It should be noted that this application is mainly used for rock slope protection in southern regions.

[0078] As an implementation method of this embodiment, a plurality of convex lenses 15 may be provided to simultaneously perform concentrated heating on the water tank 14 .

[0079] It should be noted that the convex lens 15 is fixed by a frame 16, and a solar follower is added to the convex lens 15 to ensure that the convex lens 15 can move with the movement of the sun, prolonging the heating time of the water. The solar follower is an existing structure, which is low-cost and can be driven by only a small solar panel to achieve automatic tracking of the sun. Since the convex lens 15 is located in an outdoor environment for a long time, it can be washed by an ordinary sprinkler every two months. It can be quickly and conveniently cleaned without climbing up for special maintenance. The clean water part falls into the reservoir and is reused after evaporation and purification for water replenishment in the dry season. There is no need to water by a pump, no high-power power supply is required, the device cost is low, and the burden of manual water replenishment is reduced. In addition, the frame 16 of the convex lens 15 can be set on the cover of the water tank 14, or it can be fixed according to the actual environment, and there is no specific limitation on this.

[0080] As a preferred implementation of this embodiment, Figure 5 As shown, the second water replenishment component includes multiple groups of external water pipes 13, each group includes multiple external water pipes 13 respectively arranged at the height of each planting hanger 3, and the multiple groups of external water pipes 13 are arranged horizontally along the planting hanger 3 to achieve uniform water replenishment for the planting hanger 3. It can be understood that Figure 7It is only one set of external water pipes 13.

[0081] Furthermore, a water tank 14 is provided corresponding to each group of external water pipes 13 , each water tank 14 is provided in the same second water reservoir 12 , and each water tank 14 is provided with a convex lens 15 .

[0082] Alternatively, the number of the second water reservoirs 12 and the number of the water tanks 14 are corresponding, and each water tank 14 is provided with a corresponding convex lens 15 .

[0083] In one embodiment, the greening slope protection structure includes a control system, and the control system includes:

[0084] A monitoring module, which monitors the soil moisture in the planting area 8 and the liquid level in the first water reservoir 7 in real time;

[0085] The judgment module receives the monitoring information of the monitoring module to judge whether the vegetation 4 is in a water shortage state. If so, it judges whether the conditions are met to enable the second water replenishment component.

[0086] The control module, when it is determined that the conditions for activating the second water replenishment component are met, issues a control instruction to activate the solar follower so that the convex lens 15 focuses the light on the water tank 14 .

[0087] Preferably, the monitoring module comprises:

[0088] A liquid level sensor, the liquid level sensor is used to obtain the liquid level height in the first water reservoir 7, and transmit the liquid level height information of the first water reservoir 7 to the judgment module;

[0089] Humidity sensor: The humidity sensor is used to obtain the soil moisture in the planting area 8 and transmit the soil moisture information in the planting area 8 to the judgment module.

[0090] Furthermore, the control system comprises:

[0091] The controller connects the monitoring module, the judgment module and the control module to transmit signals and send instructions. The controller realizes signal transmission and work instruction issuance between modules.

[0092] Actuator, the actuator is connected to the controller and executes the control instructions of the control module. The solar follower is enabled by the actuator to drive the convex lens to rotate according to the position of the sun.

[0093] By setting a control system to control the second water replenishment component to replenish water for the vegetation 4, when it rains, the second water reservoir 12 will collect rainwater. In the short interval between rainfall and rain, the soil moisture in the planting area 8 is relatively high, and the vegetation 4 does not need to be replenished with water. However, when it is sunny, the convex lens 15 will act on the water tank 14 to heat the water in the water tank 14, and the water in the water tank 14 that has just experienced rainfall is sufficient, and unnecessary water will be provided to the vegetation 4 through the second water replenishment component. Therefore, a control system is set to monitor the soil moisture in the planting area 8 and the first water reservoir 7. Liquid level. If the soil moisture reaches or exceeds the preset value, it is determined that the vegetation 4 is not in a water shortage state and the second water replenishment component is not activated. If the soil moisture is lower than the preset value, but the liquid level in the first water reservoir 7 is higher than the liquid level preset value, the vegetation 4 is replenished with water only through the first water reservoir 7 and the first water replenishment component, and the water in the second water reservoir 12 and the water tank 14 is retained. On the one hand, excessive water replenishment of the vegetation 4 is avoided, and on the other hand, excessive consumption of water in the first water reservoir 7 and the second water reservoir 12 is avoided at the same time, resulting in the inability to provide water replenishment later.

[0094] The activation of the second water replenishment component is achieved by activating the sun follower. When the sun follower is activated, it drives the convex lens 15 connected to it to follow the rotation, so that the convex lens 15 can keep focusing light on the water tank 14 when the sun's position is different, so that the water in the water tank 14 continues to heat up, and then generates water vapor to move along the external water pipe 13 to achieve water replenishment for the vegetation 4.

[0095] The present solution also provides a greening slope protection method applied to the above control system, the method comprising: determining whether the vegetation 4 is in a water shortage state, and if so, determining whether the second water replenishment component meets the activation condition, wherein determining whether the vegetation 4 is in a water shortage state comprises:

[0096] Determine whether the soil moisture of the planting area 8 is lower than a preset soil moisture, and if so, determine that the vegetation 4 is in a water shortage state;

[0097] If the vegetation 4 is in a water shortage state, it is determined whether the activation condition of the second water replenishment component is met, wherein the activation condition includes: determining whether the liquid level in the first water reservoir 7 is lower than a preset liquid level, and if so, activating the second water replenishment component.

[0098] The method in the present application determines whether to activate the second water replenishment component to replenish water to the vegetation 4 by judging the humidity of the soil and the liquid level of the first water reservoir 7, wherein the soil humidity of the planting area 8 is monitored and the monitored soil humidity data is compared with the preset data to determine whether the current soil humidity can meet the survival needs of the vegetation 4. If the preset humidity is not reached, it is determined that the vegetation 4 is in a water shortage state. This method requires the installation of a humidity sensor in the planting area 8 for monitoring. The required structural components are simple and easy to set up, and the setting of the preset soil humidity can be obtained according to the type of vegetation 4 planted and the growth law of the vegetation 4. If the preset soil humidity can be reached, no matter whether the liquid level in the first water reservoir 7 is lower than the preset liquid level, there is no need to activate the second water replenishment component, thereby realizing water replenishment when the vegetation 4 needs it, and it is beneficial to retain and store the water in the second water reservoir 12 and the water tank 14 for backup.

[0099] At the same time, in this method, the liquid level in the first water reservoir 7 is monitored, and the monitored liquid level data is compared with the preset liquid level. In the method, the second water replenishment component is activated only when the soil moisture is lower than the preset soil moisture and the liquid level in the first water reservoir 7 is lower than the preset liquid level. If the soil moisture is lower than the preset soil moisture, but the liquid level in the first water reservoir 7 reaches or exceeds the preset liquid level, the vegetation 4 can be replenished with water only through the first water replenishment component, and the water in the second water reservoir 12 can be retained. A liquid level sensor is set in the first water reservoir 7. This structure is easy to install and implement, and the selection of the preset liquid level can be set according to the height of the internal water pipe in the first water reservoir 7, that is, by judging whether the internal water pipe can draw water from the first water reservoir 7 to determine whether the preset liquid level is reached, it can be relatively simple to determine whether the internal water pipe can transport water to the vegetation 4.

[0100] In one embodiment, the control part of the solar follower adopts a control method of comparing the light intensity of photovoltaic cells. Through the reasonable layout of photovoltaic cells, the data acquisition part can timely reflect the small or large changes in sunlight. It is completely controlled by electronic circuits without external mechanical control, and the cost is low. The solar follower performs dual-axis tracking of the solar altitude angle and azimuth angle to control the solar follower to quickly keep up with the sun. This method can be achieved with the help of existing technology.

[0101] In one embodiment, if Figure 6 , Figure 7 As shown, the internal water pipe includes a transverse water pipe and a vertical water pipe, and both ends of the transverse water pipe are respectively connected to two vertical water pipes.

[0102] By setting up the horizontal water pipe and the vertical water pipe, the water in the reservoir can be quickly circulated and guided in different directions, which is beneficial to improving the water replenishment efficiency of the vegetation 4 in the planting area 8. The horizontal water pipe connects the two vertical water pipes, which is beneficial to transfer the water in the vertical water pipe to the soil layer of the planting area 8 with the help of the horizontal water pipe, and is beneficial to increase the coverage area of ​​the internal water pipe in the planting area 8, providing rapid and uniform water replenishment for the planting area 8.

[0103] Preferably, the transverse water pipe is located in the planting area 8, and both ends of the vertical water pipe are located in the planting area 8 and the first water reservoir 7 respectively.

[0104] Preferably, the inner wall of the internal water pipe is provided with a water absorbing member 5 and the pipe wall of the internal water pipe is provided with a plurality of water holes 11. The water absorbing member 5 is provided on the inner wall of the internal water pipe, and water is transferred to the planting area 8 through the water holes 11 of the internal water pipe. Since the water storage area is below the planting area 8, the excess precipitation in the rainy season will be stored in the water storage area, and the water in the water storage area will be transported to the planting area 8 through the water holes 11 through the internal water pipe in the dry season, ensuring that the vegetation 4 in the planting area 8 will not die in the dry season, without the need for artificial watering, and the vegetation 4 can grow normally, thereby achieving the protection effect of the rock slope 1.

[0105] The internal water pipe is provided with a plurality of water holes 11. The water in the first water reservoir 7 enters the internal water pipe through the water holes 11, and the water in the internal water pipe in the planting area 8 is discharged to the soil layer of the planting area 8 through the water holes 11, so as to replenish the planting area 8 with water during the dry season, provide the vegetation 4 with the water required for survival, prevent the vegetation 4 from withering, and avoid or reduce the number of manual watering. In addition, the water holes 11 are conducive to improving the water conduction efficiency of the internal water pipe, quickly replenishing the planting area 8 with water, and when a certain water hole 11 is blocked, it will not affect the water delivery effect of the internal water pipe, thereby improving the fault tolerance of the structure.

[0106] As a preferred implementation mode, Figure 4 As shown, the water holes 11 are arranged in a long strip shape, extending along the axial direction of the internal water pipe, and arranged circumferentially around each internal water pipe. Arranging multiple water holes 11 is conducive to improving the water conduction efficiency of the internal water pipe, quickly replenishing water for the planting area 8, and when a water hole 11 is blocked, it will not affect the water delivery effect of the internal water pipe, thereby improving the fault tolerance of the structure.

[0107] Further, in one embodiment, if Figure 6 As shown, a support frame 6 is provided inside the planting hanger 3 , a water absorbing member 5 is provided on the inner wall of the planting hanger 3 , and the support frame 6 includes a limiting bracket 61 that abuts against the water absorbing member 5 so that the water absorbing member 5 fits against the inner wall of the planting hanger 3 .

[0108] The structural strength of the planting hanger 3 is improved by the support frame 6, and the planting hanger 3 is internally partitioned, so that a first water reservoir 7 is formed inside the planting hanger 3 below the planting area 8 to prevent excessive moisture in the soil of the planting area 8, and no artificial drainage is required during the rainy season. The water absorbing member 5 is pressed against the inner wall of the planting hanger 3 by the limiting bracket 61, and the water absorbing member 5 located on the inner wall is replenished from the edge of the planting area 8, that is, the inner wall of the planting hanger 3.

[0109] Preferably, the water absorbing member 5 is made of wool felt, which is laid along the inner wall of the planting hanger 3, and the support frame 6 and the water pipe are placed on the wool felt. It can be understood that the outer ring shape of the support frame 6 is similar to that of the planting hanger 3, and the outer ring frame size of the support frame 6 is as close as possible to the size of the planting hanger 3, so that the wool felt can be clamped between the support frame 6 and the planting hanger 3, and the wool felt can be attached to the inner wall of the planting hanger 3 through the support of the support frame 6.

[0110] Preferably, the support frame 6 includes a transverse support 62 separating the planting area 8 and the first water reservoir 7 and a cable-stayed beam 63 connecting the transverse support 62 and the limiting support 61, and the cable-stayed beam 63 is connected to the limiting support 61 and the transverse support 62 to form a triangular support frame.

[0111] By setting up a transverse bracket 62 and a cable-stayed beam 63, which are connected and cooperated with the limit bracket 61, the supporting strength of the limit bracket 61 is strengthened. At the same time, the first water reservoir 7 and the planting area 8 are separated by the transverse bracket 62. The cable-stayed beam 63 is connected to the transverse bracket 62 to strengthen the connection stability between the transverse bracket 62 and the limit bracket 61, thereby ensuring the overall structural stability of the support frame 6.

[0112] In one embodiment, several layers of filter paper are laid on the top of the transverse support 62. The filter paper layer 81 is formed between the planting area 8 and the first water reservoir 7 by the multiple layers of filter paper. The filter paper layer 81 can play the effect of water permeability but not soil permeability, thereby preventing the soil in the planting area 8 from being washed by rainwater and falling into the first water reservoir 7. On the one hand, it is conducive to ensuring the planting effect of the planting area 8 on the vegetation 4, and on the other hand, it prevents the soil layer from falling into the first water reservoir 7 for water absorption, thereby ensuring that the first water reservoir 7 can supply water in the dry season.

[0113] It is understandable that the water-absorbing member 5 described herein may be made of wool felt, or other water-absorbing materials such as plant fibers may be used to replace wool felt as the water-absorbing member 5 .

[0114] Furthermore, in one embodiment, a vertical water pipe is set to pass through the junction of the planting area 8 and the water storage area, and the extension length of the vertical water pipe is at least two-thirds of the height of the water storage area to ensure that the vertical water pipe can transfer water to the planting area 8 even when the water volume is small.

[0115] In addition, the portion of the vertical water pipe extending into the planting area 8 runs through the entire planting area 8, thereby ensuring that it transports water to the nutrient layer 84 and the clay layer 83 located above during the dry season.

[0116] Preferably, the internal water pipe is made of PVC material, which has excellent surface hardness and tensile strength, and the pipeline has a very high safety factor, good aging resistance, long service life, and excellent corrosion resistance to inorganic acids, alkalis, salts and other substances, so it is suitable for water transportation. In addition, the friction coefficient of this material is small, the water flow is smooth, it is not easy to be blocked, and the maintenance workload is small. At the same time, this type of pipeline has a small deformation due to temperature, a small thermal conductivity and elastic modulus, and excellent anti-freezing properties, which is suitable for outdoor environments. During installation, the connection can be made by bonding, which is simple to construct, easy to operate, and has high installation efficiency.

[0117] This scheme also includes another rock slope greening and slope protection method, which is applied to the above-mentioned greening and slope protection structure, and the method includes:

[0118] Step 1: Slope cutting: trimming and cleaning the rock slope 1, and constructing the second water reservoir 12 at the bottom of the rock slope;

[0119] Step 2: fixing a plurality of the planting hangers 3 provided with the first water reservoir 7 and the first water replenishment assembly at intervals along the height direction on the rock slope 1;

[0120] Step 3: laying a gravel sand layer 82, a clay layer 83 and a nutrient layer 84 in the planting area in sequence and planting green vegetation 4;

[0121] Step 4: Laying the second water replenishment assembly, wherein the external water pipe 13 is respectively provided at each of the planting hangers 3 .

[0122] Specifically, in step 1, the rock slope 1 is trimmed according to the designed slope, and weeds, pumice and loose soil on the slope are cleaned. A second water reservoir 12 is set according to the horizontal length of the planting hanger 3 to facilitate the external water pipe 13 to guide water at different horizontal positions, ensuring that each planting hanger 3 can achieve uniform water replenishment.

[0123] like Figure 1 , Figure 2As shown, in step 2, holes are set every 2m to 3m in the height direction and every 2m to 3m in the length direction on the rock slope 1 to allow the anchor rod 2 to be inserted. After the drilling is completed, compressed air or flushing fluid is used to remove debris and mud in the hole to ensure that the inside of the borehole is clean so that the anchor rod 2 can be smoothly inserted to fix the planting hanger 3. The planting hanger 3 is placed at the completed borehole, and the anchor rod 2 passes through the planting hanger 3 and is inserted into the borehole, and then grouting is performed in the borehole. Cement slurry, mortar or chemical slurry can be used as the grouting material during grouting. After the slurry solidifies, the anchor rod 2 can be fixed, thereby fixing the planting hanger 3 on the rock slope 1.

[0124] Furthermore, if Figure 6 As shown, the planting area 8 includes a gravel and sand layer 82 , a clay layer 83 and a nutrient layer 84 .

[0125] In a preferred embodiment, the particle size of the gravel in the gravel layer 82 is 0.5-5 mm, and the particle size of the clay in the clay layer 83 is less than 0.075 mm. The gravel layer 82 and the clay layer 83 are laid in sequence. According to the capillary retardation theory, the water is blocked at the interface between the gravel layer 82 and the clay layer 83 by the suction force of the capillary action, forming a capillary water belt, which limits the water from penetrating downwards. By making the permeability coefficients of the gravel layer 82 and the clay layer 83 different, the water storage capacity of the upper soil layer is improved, thereby further preventing the vegetation 4 from dying due to lack of water in the dry season.

[0126] The gravel sand layer 82 and the clay layer 83 are alternately laid in multiple layers, which is beneficial to improving the soil water storage effect of the planting area 8, and cooperates with the first water storage tank 7 and the internal water pipe located in the lower layer of the planting area 8 to provide the water required by the vegetation 4 in the dry season.

[0127] In one embodiment, the nutrient layer 84 comprises a plurality of ingredients:

[0128] Peat soil: Peat soil is rich in organic matter, which can improve soil fertility, enhance soil water retention capacity and aeration;

[0129] Mineral composition: sand, gravel and clay. Sand and gravel can improve soil drainage and prevent water accumulation, while clay can increase soil water retention and nutrient retention capacity.

[0130] Fertilizer: Nitrogen fertilizer (such as urea, ammonium nitrate) is beneficial to promote vegetation growth; phosphorus fertilizer (such as diammonium phosphate, superphosphate) promotes root development; potassium fertilizer (such as potassium sulfate, potassium chloride) improves plant resistance;

[0131] Soil conditioners: such as gypsum, used to improve soil structure and increase calcium content. Or such as perlite and vermiculite: used to improve soil drainage and aeration.

[0132] Trace elements: such as iron, manganese, zinc, copper, etc.

[0133] Lime or sulfur: Used to adjust the pH of the soil to make it more suitable for vegetation 4. Lime is used to neutralize acidic soils, while sulfur is used to lower the pH of alkaline soils.

[0134] Water retaining agent: In arid areas or places with little precipitation, adding water retaining agent (such as sodium polyacrylate) can increase the water retention capacity of the soil.

[0135] It should be noted that the nutrient layer 84 is located at the top layer of the planting hanger 3, and the clay layer 83 is located between the nutrient layer 84 and the gravel and sand layer 82. Since the particle sizes of the gravel and sand layer 82 and the clay layer 83 are different, according to the capillary retardation theory, the water is blocked at the interface between the gravel and sand layer and the clay layer through the suction force of the capillary action to form a capillary water belt, thereby limiting the water from continuing to penetrate downward. This laying method can utilize the difference in permeability coefficients between the two layers of soil to improve the water storage capacity of the upper soil.

[0136] In a preferred embodiment, step 3 specifically further comprises: selecting taproot vegetation and fibrous root vegetation as greening vegetation 4, such as vetiver and Bermuda grass. Specifically, plant vetiver seedlings in the rainy season and cloudy days from March to June, with a planting density of 4-6 plants / ㎡ and a plant spacing of 20-30 cm, insert the vetiver stem segments into the soil to a depth of about 10-15 cm, and then compact the soil.

[0137] Bermuda grass can be sown in spring and summer when the temperature is above 15℃. The sowing density is 10-15 grams of seeds per square meter. After sowing, cover the soil so that the seed depth reaches 0.5-1cm and compact the soil.

[0138] An appropriate amount of nitrogen fertilizer can be applied within 1-2 months after vegetation 4 is sown.

[0139] It is understandable that taproot vegetation and fibrous root vegetation can be sown in the same planting hanger 3. And taproot vegetation and fibrous root vegetation can be planted alternately.

[0140] Through the method in this scheme, in step four, multiple or multiple groups of external water pipes 13 can be set according to the positions of the planting hangers 3 set in the above method, so that each planting hanger 3 can be replenished with water through the external second water reservoir 12, thereby realizing the coordinated operation of internal and external water replenishment, increasing soil moisture in the dry season, and reducing the workload of manual maintenance of the rock slope 1 slope protection work.

[0141] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0142] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0143] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
