Description

Technical Field

[0001] The present invention relates to the technical field of retaining walls, and specifically to an ecological retaining wall structure and a construction method thereof. Background Art

[0002] A retaining wall is a common engineering structure mainly used to protect the stability of a soil slope, prevent soil collapse and sliding. It is composed of concrete blocks or metal plates, can withstand external forces and pressures, and separates buildings and sites. It is widely used in places where buildings need to be separated, such as residential areas, etc. It is favored for its durability and easy maintenance, and greening plants, etc. are placed outside the retaining wall for functions such as garden decoration.

[0003] In the patent with the publication number Cn221721711U, an ecological greening concrete ecological retaining wall structure is disclosed, which includes a bearing frame plate. A placing device is arranged on the front of the bearing frame plate, and a protection device is arranged on the front of the placing device. The placing device includes a back end plate member, a placing frame, a placing cylinder member, a surface support ring frame, an inner placing frame, a suction cup, a ventilation pipe, a connecting air pipe, a connecting column member, an air suction pump, and a box member. The back end plate member is fixedly connected to the side of the bearing frame plate, the placing frame is fixedly connected to the front of the back end plate member, and the connecting column member is fixedly connected to the top of the placing frame. In this ecological greening concrete ecological retaining wall structure, by setting the placing device, the suction can be shunted under the action of the ventilation pipe, and suction can be generated at the top of each suction cup to adsorb the placed potted plants, and the adsorption can be stable after placement to avoid the falling of the greening potted plants, and the setting of multiple groups of greening potted plants can ensure the placement effect. However, this ecological retaining wall structure still has the following problems: It contacts the concrete slope through the bearing frame plate and the back end plate member, and no additional abutting and fixing structure is provided, resulting in the disadvantages of poor overall stability and safety.

[0004] A patent with the publication number Cn116114581B discloses a power-free drip irrigation system based on an assembled retaining wall, including: a retaining wall module, which includes a supporting wall, a planting bottom plate, and an extended outer plate. A through hole is opened in the center of the planting bottom plate, and a soil layer is provided on the planting bottom plate; a drip irrigation assembly, which is arranged in the retaining wall module through the through hole; a water storage tank; wherein, the top and bottom of several retaining wall modules are spliced with each other to form an ecological retaining wall. When there is water in the water storage tank, the water source can be transported to the soil layer in the retaining wall module through the drip irrigation assembly to irrigate the soil layer, ensuring the moisture of the soil layer. The drip irrigation assembly can irrigate the soil layer for a long time, avoiding the cracking of the soil layer due to lack of water source moisture in dry weather. However, this drip irrigation system requires an additional water storage tank, which has the disadvantages of complex structure, poor overall stability and safety. In addition, the drip irrigation assembly is buried in the soil, and the module needs to be excavated for maintenance. After long-term use, mosquitoes, algae are likely to breed in the water storage layer; the drip irrigation assembly is easily blocked by impurities (such as soil particles, algae), and the water volume distribution between modules depends on manual regulation, which may lead to local over-wetting or drought.

[0032] S50) placing a greening pot in the through groove of the placement table, and planting plants in the greening pot;

[0033] S60) Install a drip irrigation assembly to provide water to the plants.

[0034] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0035] 1. During installation, the present invention excavates and levels the predetermined foundation position to ensure the flatness and stability of the foundation. The embedded components are fixed by pouring concrete. After the embedded components solidify, the next step of installation is performed. The retaining wall components are wrapped by external templates. Concrete is poured on the retaining wall components to complete the overall production of the retaining wall. After the retaining wall components are installed, the connection components are installed. The placement components and drip irrigation components are installed on the support seat to complete the installation of the entire ecological retaining wall structure. When the ecological retaining wall structure is subjected to soil pressure, the soil pressure first acts on the casting. The casting transmits the force to the substrate through the support frame, and then the substrate transmits the force to the foundation through the embedded components. The close connection between the embedded components in the embedded components and the foundation ensures the effective transmission and dispersion of force, and avoids structural damage caused by excessive local force. In this way, the present invention provides a highly stable ecological retaining wall structure through the design of embedded components, retaining wall components and connection components, which can effectively resist soil pressure and prevent landslides or collapses; the design of anti-debonding reinforcement makes the connection between the embedded components and the concrete more firm. During the solidification process of concrete, the anti-stripping reinforcement forms a close bite relationship with the concrete, which improves the tensile strength and shear strength of the connection. The addition of placement components and drip irrigation components makes the ecological retaining wall structure not only practical, but also ecological and aesthetic, improving the quality of urban space. The automatic irrigation function of the drip irrigation component reduces the workload of manual maintenance, making the maintenance of the ecological retaining wall structure more convenient.

[0036] 2. The anti-slip reinforcement of the present invention adopts a three-dimensional intersecting "M"-shaped structure, and each end thereof is connected to the inner wall of the base frame by penetrating welding. In this way, the three-dimensional intersecting "M"-shaped structure of the present invention forms six directions of spatial constraints (front and back, left and right, diagonal), increases the anchoring direction, and improves the pull-out resistance; in addition, the "M"-shaped reinforcement increases the effective constraint area of ​​the concrete.

[0037] 3. When irrigation is needed in the present invention, the control system sends an opening signal to the first solenoid valve, and the external water source enters the drip irrigation system through the vertical water delivery main pipe. According to the preset irrigation strategy or the information fed back by the sensor, the control system sends an opening signal to the corresponding second solenoid valve. The water flow enters the corresponding horizontal water delivery pipe through the opened second solenoid valve and irrigates the plants below in the form of small and uniform water droplets through the drip irrigation nozzles. When the preset irrigation time is reached or the soil humidity meets the requirements, the control system sends a closing signal to the solenoid valve to stop irrigation. In this way, the drip irrigation component of the present invention can achieve precise, efficient, and automated irrigation of multi-layer plants, improving the space utilization rate of the ecological retaining wall structure and the growth quality of plants.

[0038] 4. Through the central controller and the precise flow calculation method, the present invention can accurately allocate the flow of the drip irrigation system according to the height information of each partition, solve the problems of insufficient water supply in the high partitions and excessive water supply in the low partitions, and improve the irrigation effect and the effective utilization of water resources.

[0039] 5. After accurately calculating the flow of each partition through Formula 1, the present invention calculates the irrigation time of the second solenoid valve of each horizontal water delivery pipe in combination with Formula 2, and adjusts the irrigation time (such as extending the time in the high area and shortening the time in the low area) to make the water volume distribution of each partition consistent and ensure uniform water volume in each partition. In addition, the present invention only needs to control the opening and closing time of the solenoid valve, and can achieve consistent water volume distribution in each partition without additionally installing sensors or flow meters, improving the water-saving efficiency and avoiding the hardware cost and maintenance complexity of sensors or flow meters.

[0065] Embodiment 1:

[0066] Please refer to Figures 1-13 as shown, the embodiment provides an ecological retaining wall structure, including a substrate 10;

[0067] A number of embedded components 20 are evenly installed on the bottom wall of the substrate 10. The embedded component 20 includes a base frame 23 with a rectangular frame structure and an embedded part 21 with anti - detachment ribs 22. The base frame 23 is fixed on the substrate 10 through fastening bolts 24 and fastening nuts 25, and the embedded part 21 is installed on the bottom wall of the base frame 23 and buried in the foundation;

[0068] A retaining wall component 30 is installed on the top wall of the substrate 10. The retaining wall component 30 includes a casting 32 and a support frame 31. The casting 32 serves as the main structural part of the retaining wall, and its bottom wall is fixed on the substrate 10 through the support frame 31;

[0069] A connecting component 40 is installed on the front wall of the casting 32. The connecting component 40 includes a butting plate 41 and a support seat 45. The butting plate 41 is installed on the front wall of the casting 32, and the support seat 45 is installed on the front wall of the butting plate 41;

[0070] A placing component 60 for placing plant pots and a drip irrigation component 50 for providing water to plants are installed on the support seat 45.

[0071] On the basis of the above - mentioned structure, during installation, excavation and leveling are carried out at the predetermined foundation position to ensure the flatness and stability of the foundation. The embedded component 20 is fixed by pouring concrete. After the embedded component 20 solidifies, the next installation step is carried out. The retaining wall component 30 is wrapped by an external formwork. Concrete is poured into the retaining wall component 30 to complete the production of the entire retaining wall. After the installation of the retaining wall component 30 is completed, the connecting component 40 is installed. The placing component 60 and the drip irrigation component 50 are installed on the support seat 45 to complete the installation of the entire ecological retaining wall structure. When the ecological retaining wall structure is subjected to soil pressure, the soil pressure first acts on the casting 32. The casting 32 transmits the force to the substrate 10 through the support frame 31, and then the substrate 10 transmits the force to the foundation through the embedded component 20. The tight connection between the embedded part 21 in the embedded component 20 and the foundation ensures the effective transmission and dispersion of the force, avoiding structural damage caused by excessive local stress. Thus, through the design of the embedded component 20, the retaining wall component 30 and the connecting component 40, the present invention provides a highly stable ecological retaining wall structure that can effectively resist soil pressure and prevent landslides or collapses; the design of the anti - detachment ribs 22 makes the connection between the embedded part 21 and the concrete more firm. During the solidification process of the concrete, the anti - detachment ribs 22 form a tight interlocking relationship with the concrete, improving the tensile strength and shear strength of the connection. The addition of the placing component 60 and the drip irrigation component 50 makes the ecological retaining wall structure not only have practical functions, but also have ecological and aesthetic properties, improving the quality of urban space. The automatic irrigation function of the drip irrigation component 50 reduces the workload of manual maintenance, making the maintenance of the ecological retaining wall structure more convenient.

[0072] In a preferred embodiment, the anti - pull - out bars 22 adopt a three - dimensional cross "rice" - shaped structure, and each end part thereof is respectively connected to the inner walls around the base frame 23 through penetration welding. In this way, the three - dimensional cross "rice" - shaped structure of the present invention forms six - direction spatial constraints (front - back, left - right, diagonal), increasing the anchoring direction and improving the anti - pull - out force; in addition, the "rice" - shaped ribs increase the area of the effective concrete constraint zone.

[0073] In a preferred embodiment, the connecting component 40 includes an abutting plate 41. The rear wall of the abutting plate 41 is attached to the front wall of the casting 32. A number of through - holes 42 are evenly formed on the front wall of the abutting plate 41. A number of fastening studs 43 are evenly fixedly installed on the front walls of a number of retaining frames. A number of fastening studs 43 are all screwed with abutting nuts 47 through the corresponding through - holes 42, and the rear walls of a number of abutting nuts 47 are attached to the front wall of the abutting plate 41;

[0074] In this embodiment, through the mutual cooperation of the abutting nuts 47 and the fastening studs 43, the abutting plate 41 can be fixedly installed on the completed retaining wall, which is convenient for the subsequent installation of the placing component 60 and the drip irrigation component 50.

[0075] Specifically, support columns 44 are fixedly installed at the four corners of the front wall of the abutting plate 41. The front ends of a number of support columns 44 are fixedly installed with the same support base 45. The support base 45 is in a "square" shape. The front wall of the support base 45 is installed with a fixing plate 46 through an abutting bolt. The front wall of the fixing plate 46 is fixedly connected to the placing component 60 and the drip irrigation component 50;

[0076] In this embodiment, under the mutual cooperation of the support columns 44 and the support base 45, and by screwing and fixing the fixing plate 46 through the abutting bolt, the fixing plate 46 can bear the placing component 60 and the drip irrigation component 50.

[0077] In a preferred embodiment, the placing component 60 includes N placing frames 61 respectively arranged on the support base 45. The N placing frames 61 are arranged in parallel along the height direction, and the vertical spacing is ≥500 mm; wherein, n≥2. Such a design not only ensures the stable placement of the plant pots, but also provides sufficient space for plant growth, while maintaining the aesthetic appearance of the ecological retaining wall structure.

[0078] In a preferred embodiment, the placing frame 61 is detachably installed on the front wall of the support base 45. A placing cavity 62 and a placing table 65 are arranged inside the placing frame 61. A through - groove is formed on the surface of the placing table 65 for placing the greening pot 66.

[0079] Based on the above structure, in the present invention, the placement rack 61 is provided with a placement cavity 62 and a placement platform 65. The placement cavity 62 provides sufficient accommodation space for the greening pot 66, enabling the greening pot 66 to be stably placed within the placement rack 61 without being prone to falling or tilting. The placement platform 65 is used to directly support the greening pot 66. Its surface is flat and firm, capable of bearing the weight of the greening pot 66 and the plants therein, ensuring the stability of the ecological retaining wall structure. A through groove is formed on the surface of the placement platform 65, and this through groove is used for placing the greening pot 66. The design of the through groove enables the greening pot 66 to be conveniently inserted and removed, facilitating greening planting, replacement, and maintenance. The size and shape of the through groove are adapted to the greening pot 66, ensuring that the greening pot 66 can be stably installed on the placement platform 65 without being prone to shaking or falling off.

[0080] In a preferred embodiment, a limiting groove 63 is provided on the top wall of the placement cavity 62. An anti-slip ring 610 and a limiting ring 69 are installed within the limiting groove 63. The bottom wall of the anti-slip ring 610 abuts against the outer wall of the greening pot 66, and the limiting ring 69 is fixed to the outer side wall of the placement rack 61 through an elastic member 67 and a clamping block 68.

[0081] Based on the above structure, the limiting groove 63 of the present invention is used to further fix and stabilize the greening pot 66. An anti-slip ring 610 is installed within the limiting groove 63, and the bottom wall of the anti-slip ring 610 abuts against the outer wall of the greening pot 66, preventing the greening pot 66 from sliding or tilting within the placement cavity 62 through friction. A limiting ring 69 is also installed within the limiting groove 63. The limiting ring 69 is fixed to the outer side wall of the placement rack 61 through an elastic member 67 and a clamping block 68. The elastic member 67 provides a certain amount of buffering and adaptability, enabling the limiting ring 69 to closely fit against the top of the greening pot 66, further restricting the movement of the greening pot 66. The clamping block 68 ensures the stable installation of the limiting ring 69 on the placement rack 61, preventing it from falling off or loosening.

[0082] In a preferred embodiment, a clamping block 68 is fixed to the bottom end of the elastic member 67. The clamping block 68 is clamped within a clamping seat 64 on the outer side wall of the placement rack 61. A water leakage opening is formed on the bottom wall of the placement rack 61. In this way, a water leakage opening is formed on the bottom wall of the placement rack 61 of the present invention, which is used to drain the water that may accumulate at the bottom of the greening pot 66, preventing water accumulation from causing root rot or bacterial growth in the greening pot 66 and maintaining a healthy growth environment for the greening pot 66.

[0083] In a preferred embodiment, the drip irrigation assembly 50 includes a vertical water delivery main pipe 51 and N horizontal water delivery pipes 52;

[0085] N horizontal water delivery pipes 52 are arranged in parallel along the height direction on the abutting plate 41, and one horizontal water delivery pipe 52 is correspondingly arranged directly above each placement rack 61. A number of evenly distributed drip irrigation nozzles 55 are arranged on each horizontal water delivery pipe 52.

[0086] A first electromagnetic valve 53 is arranged at the water inlet end of the vertical water delivery main pipe 51, and a second electromagnetic valve 54 is arranged at the water inlet end of each horizontal water delivery pipe 52.

[0087] Based on the above structure, when irrigation is required, the control system sends an opening signal to the first electromagnetic valve, and the external water source enters the drip irrigation system through the vertical water delivery main pipe. According to the preset irrigation strategy or the information fed back by the sensor, the control system sends an opening signal to the corresponding second electromagnetic valve. The water flow enters the corresponding horizontal water delivery pipe through the opened second electromagnetic valve and irrigates the plants below in the form of small and uniform water droplets through the drip irrigation nozzles. When the preset irrigation time is reached or the soil humidity meets the requirements, the control system sends a closing signal to the electromagnetic valve to stop irrigation. In this way, the drip irrigation component of the present invention can achieve precise, efficient, and automated irrigation of multi-layer plants, improving the space utilization rate of the ecological retaining wall structure and the growth quality of plants.

[0088] In a preferred embodiment, the drip irrigation component further includes a central controller. The signal output end of the central controller is respectively connected to the signal input ends of the first electromagnetic valve and the second electromagnetic valve; the central controller accurately calculates the flow rate of each partition through Formula 1;

[0089]

[0090] In Formula 1, Q i is the flow rate of the i-th partition (unit: m 3 / h); Q total is the total water supply (unit: m 3 / h); α is the hydraulic loss coefficient (dimensionless, usually taken as 0.8); h wall is the total height of the retaining wall (unit: m); z i、 z j are the center point heights of the i-th and j-th partitions respectively (unit: m); n is the total number of partitions (n = len(z list ))), and the ecological retaining wall structure is divided into n partitions by N horizontal water delivery pipes.

[0091] Calculation of the weight factor: The weight factor of each partition is 1 + α×(h wall -z i ), indicating the proportion of the increased flow rate required for the partition at a higher position due to the loss of gravitational potential energy.

[0092] Partition at a higher position: z i close to h wall→Large weight factor → High flow rate percentage.

[0093] Lower partition: Small weight factor → Low flow rate percentage.

[0094] Normalization: Normalize by the sum of the weight factors to ensure that the total flow rate of each partition is strictly equal to Q. total .

[0095] Example verification:

[0096] Scenario: Uniform partition (5 partitions, 2 meters per partition).

[0097] Input parameters: h wall = 10m, Q total = 5m 3 / h, a = 0.8. Z list = [1, 3, 5, 7, 9].

[0098] Calculation process:

[0099] 1. Weight factor:

[0100] Z = 1, weight factor 1 + 0.8x(10 - 1) = 8.2;

[0101] Z = 3, weight factor 1 + 0.8x(10 - 3) = 6.6;

[0102] Z = 5, weight factor 1 + 0.8x(10 - 5) = 5.0;

[0103] Z = 7, weight factor 1 + 0.8x(10 - 7) = 3.4;

[0104] Z = 9, weight factor 1 + 0.8x(10 - 9) = 1.8;

[0105] 2. Sum of weights: 8.2 + 6.6 + 5.0 + 3.4 + 1.8 = 25;

[0106] 3. Allocate the total flow rate according to the weight ratio: The flow rate of each partition is calculated as follows:

[0107] First partition, Z = 1, Q1 = 5×(8.2 / 25) = 1.64m 3 / h;

[0108] Second partition, Z = 3, Q2 = 5×(6.6 / 25) = 1.32m 3 / h

[0109] Third partition, Z = 5, Q3 = 5×(5.0 / 25) = 1.0m 3 / h;

[0110] Fourth zone, Z = 7, Q4 = 5×(3.4 / 25) = 0.68 m 3 / h;

[0111] Fifth zone, Z = 9, Q5 = 5×(1.8 / 25) = 0.36 m 3 / h;

[0112] Total verification: 1.64 + 1.32 + 1.0 + 0.68 + 0.36 = 5 m 3 / h.

[0113] In this way, through the central controller and the precise flow calculation method, the present invention can accurately distribute the flow of the drip irrigation system according to the height information of each zone, solve the problems of insufficient water supply in the high zones and excessive water supply in the low zones, and improve the irrigation effect and the efficient utilization of water resources.

[0114] In the first aspect of the present invention, as an optional embodiment, the central controller converts the water volume of each zone into the irrigation time of each zone according to Formula 2, so as to accurately control the opening and closing time of the second solenoid valve of each horizontal water pipe, and achieve the consistent water volume distribution of each zone;

[0115] Formula 2:

[0116] In Formula 2, T i is the irrigation time of the i-th zone (unit: h), V i is the water volume of the i-th zone (unit: m 3 ), Q i is the flow of the i-th zone (unit: m 3 / h).

[0117] Example verification:

[0118] Calculate the flow of each horizontal water pipe (such as Q1 = 1.64 m 3 / h, Q2 = 1.32 m 3 / h, Q3 = 1.0 m 3 / h, Q4 = 0.68 m 3 / h, Q5 = 0.36 m 3 / h) in the example.

[0119] Convert to irrigation time:

[0120]

[0121] If it is necessary to ensure that the water volume of each zone is consistent, V i = 1 m 3 , then:

[0122] T1 = 1 / 1.64 ≈ 0.61 hours;

[0123] T2 = 1 / 1.32 ≈ 0.76 hours;

[0124] T3 = 1 / 1.0 = 1 hour;

[0125] T4 = 1 / 0.68 ≈ 1.47 hours

[0126] T5 = 1 / 0.36 ≈ 2.78 hours.

[0127] In this way, after accurately calculating the flow rates of each partition through Formula 1, the present invention calculates the irrigation time of the second solenoid valve of each horizontal water delivery pipe in combination with Formula 2, and adjusts the irrigation time (such as extending the time in the high area and shortening the time in the low area), so as to make the water volume distribution of each partition consistent and ensure uniform water volume in each partition. In addition, the present invention only needs to control the opening and closing time of the solenoid valve, and can achieve consistent water volume distribution in each partition without additionally installing sensors or flow meters, improving the water-saving efficiency and avoiding the hardware cost and maintenance complexity of sensors or flow meters.
