Description

Technical Field

[0001] This invention relates to the field of ditch technology, and more particularly to a prefabricated ditch. Background Technology

[0002] There are two main methods for preparing and installing ditches: one is rubble masonry construction, and the other is on-site installation of precast ditch bodies. Rubble masonry construction, as the most traditional construction method, has the disadvantages of long construction period and high cost; precast ditch bodies have the advantages of convenient transportation and flexible installation, and have been widely used in the field of ditch technology.

[0003] Precast trenches are also classified according to the materials used. For example, a lightweight embankment side ditch with application number 201921203998.X discloses a crushed stone cushion layer at the bottom of the ditch and a mortar cushion layer for the side walls of the ditch. The side walls of the ditch are integrally cast with concrete, which still has a large weight and is relatively difficult to install. The adjacent side walls of the ditch cannot be positioned and connected to ensure the overall stability.

[0004] For example, the prefabricated ditch with application number 202022024719.2 discloses that the left and / or right ends of the plate-shaped body are provided with mortises for inserting ditch side plates or through grooves extending along the length of the plate-shaped body. The ditch side plates can be inserted into the mortises or through grooves for fixing. The ditch assembly is completed on the construction site. The installation and fixing method of the side plates is also very simple, which has the characteristics of higher construction efficiency and shorter construction period. However, it is only a connection between the sheet pile body and the ditch side plates. There is no connection between adjacent units, which may lead to the instability of the entire ditch.

[0005] For example, the composite prefabricated agricultural irrigation ditch with application number 202020637947.4 discloses that multiple bottom plates are connected end to end to form the bottom of the ditch, and multiple side plates are connected end to end to form the wall of the ditch. The wall of the ditch is inserted into the bottom of the ditch. In this application, both the side plates and the bottom plates are made by extrusion. Due to the limitations of the extrusion molding process, a transverse locking structure with locking strips and locking grooves can be formed between the side plates, but a locking or snap-fit ​​structure cannot be effectively formed on the bottom plate. Therefore, the connection stability between adjacent units cannot be effectively guaranteed. Summary of the Invention

[0006] The purpose of this invention is to provide a prefabricated ditch, in which a side plate has a second buckle and a second guide on both sides. The second buckle and the second guide cooperate with the first buckle and the first guide on the bearing plate respectively to realize the positioning and abutment of the side plate on two bearing plates. This can facilitate the series connection of multiple bearing plates and the installation of the side plate. In addition, the locking structure can realize the stability of the bottom connection of a pair of bearing plates.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a prefabricated ditch, comprising:

[0008] A support plate includes a base plate and a pair of extension plates formed at both ends of the base plate and forming an angle with the base plate. At least one first positioning structure is provided on each opposite side of the upper end of the sidewall of the extension plates near the ditch slope. The first positioning structure includes a first guide member and a first buckle formed on the extension plate or the first guide member.

[0009] The side plate has at least one second positioning structure on each of the opposite sides of the lower end of the side wall near the ditch slope. The second positioning structure includes a second guide and a second buckle formed on the side plate or the second guide.

[0010] A cavity structure for embedding the other is formed in one of the first guide member and the second guide member.

[0011] When the pair of bearing plates abut, the first guide members on both plates that are close to each other are nested with the second guide members at different positions on the same side plate, and the first latches on both plates that are close to each other are engaged with the second latches at different positions on the same side plate.

[0014] As a further optimization, a first buckle and a first guide are provided at the middle position of the upper end of the side wall near the ditch slope on the extension plate for connecting one or more of the side plates.

[0015] As a further optimization, the first guide member has a socket, and the second guide member is a rod that extends into the socket.

[0016] As a further optimization, the insertion rod is provided with a limiting protrusion, which abuts against the edge of the insertion port.

[0017] As a further optimization, the opposite side walls of the bearing plate are respectively provided with a first cover plate and a first pad protruding from their bodies. When a pair of bearing plates abut against each other, the first cover plate abuts against the first pad. And / or, the opposite side walls of the side plate are respectively provided with a second cover plate and a second pad protruding from their bodies. When a pair of side plates abut against each other, the second cover plate abuts against the second pad. The cooperation of the cover plate and the pad can improve the sealing performance at the connection of a pair of bearing plates.

[0018] As a further optimization, the prefabricated ditch also includes a locking structure, through which at least one pair of the bearing plates are connected; the locking structure includes a third buckle and a fourth buckle, the lower end of the third buckle is provided with a first groove opening downwards, and the upper end of the fourth buckle is provided with a second groove opening upwards; the third buckle is provided on the bottom plate of one bearing plate, and the fourth buckle is provided on the bottom plate of the other bearing plate; when a pair of bearing plates abut against each other, the free end of the third buckle is embedded in the second groove, and the free end of the fourth buckle is embedded in the first groove, and both the first pad and the first cover plate are provided with gaps for accommodating the locking structure.

[0019] As a further optimization, the upper surface of the third buckle is flush with the upper surface of the base plate on which it is located, and the lower surface of the fourth buckle is flush with the lower surface of the base plate on which it is located, which can ensure the flatness after assembly.

[0020] As a further optimization, the sidewalls of the third and fourth buckles on the side away from the base plate are both perpendicular to the base plate; the vertical projection of the upper horizontal section in the first slot is included in the vertical projection of the lower horizontal section, and the vertical projection of the lower horizontal section in the second slot is included in the vertical projection of the upper horizontal section.

[0021] As a further optimization, the free ends of the third buckle and / or the fourth buckle are provided with guide slopes, and the smooth engagement of the two buckles is achieved through the mutual guidance and mutual clearance between the guide slopes, as well as the deformation and recovery between the third buckle and the fourth buckle.

[0022] As a further optimization, when a third buckle and a fourth buckle are provided on the same side wall of the base plate, the projections of the third buckle and the fourth buckle on the plane of the base plate do not overlap.

[0023] As a further optimization, when a third buckle and a fourth buckle are provided on the same side wall of the base plate, the sides of the projections of the third buckle and the fourth buckle in the plane of the base plate abut against each other.

[0024] As a further optimization, when a third buckle and a fourth buckle are provided on the same side wall of the base plate, and the sum of the number of the third buckle and the fourth buckle is n, when n≥3, the third buckle and the fourth buckle are alternately set, which can ensure the connection stability of the locking structure.

[0025] As a further optimization, both the third and fourth buckles include a main body section and a snap-fit ​​section. The main body section is integrally formed with the base plate. The main body section includes a connecting part and an insert part. The snap-fit ​​section is provided with a slot. The slot is interference-fitted into the insert part to connect the snap-fit ​​section to the main body section.

[0026] As a further optimization, the extension plate has limiting cylinders on both sides of one end and limiting grooves on both sides of the other end. A pair of limiting cylinders are respectively embedded in a pair of limiting grooves to rotatably connect one of the bearing plates relative to the other bearing plate.

[0027] As a further optimization, a limiting platform is provided at the end of the limiting cylinder.

[0028] As a further optimization, the extension plate is provided with a clearance notch on the side of the limiting cylinder and the limiting groove.

[0029] As a further optimization, a sealing plate is provided on the side plate, which is embedded in the clearance notch after the pair of extension plates abut against each other, which can ensure the flatness after assembly.

[0030] As a further optimization, the prefabricated ditch also includes a locking structure and a planting frame. The planting frame includes at least a surrounding panel and a limiting plate disposed within the surrounding panel. The limiting plate is provided with growth holes for plants to pass through, and the side panel is provided with an installation opening. The planting frame is embedded in the installation opening, which can enrich the ecological diversity within the ditch.

[0031] As a further optimization, the planting frame also includes a porous rib-like body, which is snapped into the enclosure and abuts against the limiting plate.

[0032] As a further optimization, the planting frame is provided with a baffle, which abuts against the side of the porous rib body away from the limiting plate.

[0033] As a further optimization, the enclosure is provided with multiple wing plates, and the side plate is provided with multiple pressure plates located in the mounting opening. At least a portion of the wing plates are pressed down by the pressure plates to abut the planting frame against the ditch slope.

[0034] As a further optimization, an anti-slip plate is provided on the side plate within the mounting opening, and at least a portion of the wing plate abuts against the anti-slip plate to support the planting frame, thereby preventing the planting frame from moving down the ditch slope.

[0035] As a further optimization, the fin plate is provided with positioning holes, and the pressure plate and / or the anti-slip plate is provided with positioning posts. The positioning holes are fitted onto the positioning posts, which can ensure the accurate positioning and stable connection between the fin plate and the pressure plate and / or the anti-slip plate.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. Both sides of a side plate have a second buckle and a second guide. By cooperating with the first buckle and the first guide on the support plate, the second buckle and the second guide can respectively position and abut against the two support plates. This installation method can more easily realize the series connection of multiple support plates and the installation of the side plate on the support plate.

[0038] 2. Based on the connection of the upper ends of adjacent bearing plates via side plates, a locking structure is provided at the bottom plate connection of adjacent bearing plates. Through the setting of the third and fourth buckles and their cooperation (the free end of the third buckle is embedded in the second slot, and the free end of the fourth buckle is embedded in the first slot), the bottom connection of the bearing plates can be limited laterally or vertically to ensure the stability of the bottom connection of the bearing plates and avoid misalignment of a pair of bearing plates laterally or vertically.

[0039] 3. Installation openings are provided on the side panels for positioning and fixing the planting frame, which can improve the aesthetics and biodiversity of the ditch;

[0040] 4. Both the support plate and the side plate can be molded structures, which can easily form the required buckles, guide parts and other structures in one piece. Compared with extrusion molding, it can form buckle structures with different structures and shapes, and is easy to demold and convenient to process; moreover, compression molding is easier to process support plates and side plates of different specifications and shapes.

[0054] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0055] like Figures 1 to 3As shown, a prefabricated ditch includes a support plate 10 and side plates 20, both of which can be molded. The support plate 10 includes a base plate 1a and a pair of extension plates 1b formed at both ends of the base plate 1a and forming an angle with the base plate 1a. At least one first positioning structure is provided on each of the opposite sides of the upper end of the sidewall near the ditch slope of the extension plate 1b. The first positioning structure includes a first guide 12 formed on the extension plate 1b and a first buckle 11 formed on the extension plate 1b or the first guide 12. At least one first positioning structure is provided on each of the opposite sides of the lower end of the sidewall near the ditch slope of the side plate 20. The dual positioning structure includes a second guide 22 formed on the side plate 20 and a second latch 21 formed on the side plate 20 or the second guide 22. One of the first guide 12 and the second guide 22 forms a cavity structure for the other to be embedded in. That is, after the two are nested together, one of them can restrict the other from lateral disengagement. When a pair of support plates 10 abut, the first guides 12 on the two plates that are close to each other are nested with the second guide 22 on one side plate 20, and the first latches 11 on the two plates that are close to each other are latched with the second latch 21 on the same side plate 20.

[0056] Preferably, in one embodiment, the first latch 11 and the second latch 21 are respectively formed on the extension plate 1b and the side plate 20. When a pair of support plates 10 abut against each other, a pair of first guide members 12 are arranged side by side on one extension plate 1b near the other support plate 10, and a first latch 11 is provided between the pair of guide members 12. Correspondingly, a pair of second guide members 22 are arranged side by side on one side of the side plate 20, and a second latch 21 is provided between the pair of second guide members 22. The nesting of the second guide member 22 (in conjunction with the support of the ditch slope for the side plate 20) and the snapping of the first buckle 11 and the second buckle 12 can position and connect one bearing plate 10 to one side of a side plate 20. Similarly, the above method can be used to position and connect another bearing plate 10 to the other side of the same side plate 20. Thus, two mutually abutting bearing plates 10 are positioned and connected by a side plate 20. Therefore, multiple side plates 20 can be used to achieve the positioning and connection of multiple series abutting bearing plates 10, thereby completing the formation of the entire ditch.

[0057] Furthermore, when the side plate 20 has a large width, one side plate 20 can abut against another side plate 20 that has the same function when positioning and connecting a pair of support plates 10; for example... Figure 4As shown, if the width of the side plate 20 is not large enough to achieve the above connection method, a first buckle 11 and a first guide 12 can be set at the middle position of the upper end of the side wall near the ditch slope on the extension plate 1b. They can cooperate with the second buckle 21 and the second guide 22 on the side plate 20 to position and connect one or more side plates 20 to the bearing plate 10, so as to realize the mutual contact of multiple side plates 20.

[0058] In another embodiment, the first buckle 11 and the second buckle 21 can also be formed on the lower end / lower part of the first guide member 12 and the lower end / lower part of the second guide member 22, respectively. When the first guide member 12 and the second guide member 22 are nested by extending inward, the first buckle 11 and the second buckle 22 engage to complete the connection between the extension plate 1a and the support plate 20.

[0059] In both of the above embodiments, regardless of whether the first buckle 11 and the second buckle 21 are formed on the plate structure or on the guide structure, the purpose is to prevent the side plate 20 from tilting to the side of the ditch slope by engaging the first buckle 11 and the second buckle 21.

[0060] Preferably, the first guide member 12 is a socket with a cavity structure, and the second guide member 22 is a rod that extends into the socket to achieve guiding and positioning.

[0061] Furthermore, a limiting protrusion 221 can be set on the insertion rod. When the second buckle 21 is engaged with the first buckle 11, the limiting protrusion 221 abuts against the edge of the insertion port. The limiting protrusion 221 can ensure the height position of the side plate 20 on the support plate 10, preventing the side plate 20 from sliding down and causing the second buckle 21 and the first buckle 11 to lose their engaging function. It can also ensure the stability of the side plate 20 on the support plate 10 by supporting the limiting protrusion 221 at the edge of the insertion port, so that the side plate 20 can still be stably supported even if it is not supported by the ditch slope.

[0062] like Figure 1 and Figure 2 As shown, to ensure the sealing of the connection between the bearing plates 10, a first cover plate 101 and a first pad plate 102 protruding from their respective sides can be provided on the opposite side walls of the bearing plates 10. When a pair of bearing plates 10 abut against each other, the first cover plate 101 abuts against the first pad plate 102. Similarly, as shown... Figure 6 and Figure 11 As shown, in order to ensure the sealing of the connection between the side plates 20, a second cover plate 201 and a second pad plate 202 protruding from the body can be provided on the opposite side walls of the side plates 20 respectively. When a pair of side plates 20 abut against each other, the second cover plate 201 abuts against the second pad plate 202. Therefore, the sealing of the ditch is improved by using the cover plate and the pad plate to achieve the misalignment of the gap.

[0063] In the above embodiment, a pair of bearing plates 10 that only abut against each other are positioned and connected only by the side plate 20. There is no connection between the pair of bearing plates 10. If the shape of the ditch bottom changes (e.g., soil erosion leading to softening or collapse), the lack of connection between the pair of bearing plates 10 may cause the connection point to sink, resulting in instability of the entire structure. Based on the above situation, if... Figures 5 to 7 As shown, the prefabricated ditch also includes a locking structure 100, which includes a third buckle 13 and a fourth buckle 14. The lower end of the third buckle 13 is provided with a first groove 130 with an opening facing downwards, and the upper end of the fourth buckle 14 is provided with a second groove 140 with an opening facing upwards. At least one third buckle 13 is provided on one side wall of the base plate 1a, and at least one fourth buckle 14 is provided on the opposite side wall. When a pair of bearing plates 10 abut against each other, the end of the first free end 131 of the third buckle 13 is embedded in the second groove 140, and the end of the second free end 141 of the fourth buckle 14 is embedded in the first groove 130. Moreover, the first cover plate 101 and the first pad plate 102 are both provided with gaps for accommodating the locking structure 100.

[0064] Specifically, a first gap 1010 is formed at a certain position on the first cover plate 101 located on the base plate 1a, and a second gap 1020 is formed at a certain position on the first pad plate 102 located on the base plate 1a. The existence of the first gap 1010 and the second gap 1020 is to allow for the formation of the third buckle 13 and / or the fourth buckle 14. Since the formation positions of the third buckle 13 and the fourth buckle 14 have multiple states, the third buckle 13 is divided into type A third buckle 13′ formed above the same plane as the first pad plate 102 and type B third buckle 13″ formed on the same plane as the first pressure plate 101. The fourth buckle 14 is divided into type A fourth buckle 14′ formed below the same plane as the first pressure plate 101 and type B fourth buckle 14″ formed on the same plane as the first pad plate 102. Among the multiple state relationships, one is that only type A third buckle 13′ is formed on one side of the base plate 1a. 3′, then according to the positional and interlocking relationship between the third and fourth buckles, the other side of the base plate 1a will only have a type A fourth buckle 14′ formed; secondly, if one side of the base plate 1a only has a type B third buckle 13″ formed, then according to the positional and interlocking relationship between the third and fourth buckles, the other side of the base plate 1a will only have a type B fourth buckle 14″ formed; thirdly, if one side of the base plate 1a simultaneously has a type A third buckle 13′ and a type B fourth buckle 14″ formed (because of molding, their vertical projections do not overlap), then... Based on the positional and interlocking relationship between the third and fourth buckles, one side of the base plate 1a simultaneously forms one type A fourth buckle 14′ and one type B third buckle 13″; or, if one side and the other side of the base plate 1a both have three or more buckles formed, for example, if one side has two type A third buckles 13′ and three type B fourth buckles 14″, then based on the positional and interlocking relationship between the third and fourth buckles, the other side will have two type A fourth buckles 14′ and three type B third buckles 13″. The above-mentioned various states... The engagement of the upper clip 13 and the fourth clip 14 can achieve the connection stability of the pair of bearing plates 10 in the lateral direction, which can prevent the pair of bearing plates 10 from separating at the bottom position. Moreover, when the third clip 13 and the fourth clip 14 are provided on one side of the bottom plate 1a, the pair of bearing plates 10 are also limited in the vertical direction after the third clip 13 and the fourth clip 14 are engaged. That is, the pair of bearing plates 10 cannot be misaligned in the vertical direction, thus ensuring the connection stability of the pair of bearing plates 10 in both the horizontal and vertical directions.

[0065] As mentioned above, when the bearing plate 10 is a molded structure, the structure and state of the third buckle 13 and the fourth buckle 14 are subject to the following limitations: the sidewalls of the third buckle 13 and the fourth buckle 14 on the side away from the base plate 1a are both perpendicular to the base plate 1a; the vertical projection of the upper horizontal section in the first slot 130 is located within the vertical projection of the lower horizontal section; the vertical projection of the lower horizontal section in the second slot 140 is located within the vertical projection of the upper horizontal section; combined with... Figure 6 and Figure 7 As shown, neither the first free end 131 of the third buckle 13 nor the second free end 141 of the fourth buckle 14 bends toward their respective slot openings, thus enabling demolding after molding. Furthermore, when the third buckle 13 and the fourth buckle 14 are simultaneously provided on the same side wall of the base plate 1a, the projections of the third buckle 13 and the fourth buckle 14 onto the plane of the base plate 1a do not overlap. This is a characteristic of molding.

[0066] Preferably, the upper surface of the third buckle 13 is flush with the upper surface of the base plate 1a, and the lower surface of the fourth buckle 14 is flush with the lower surface of the base plate 1a, which can ensure the consistency of the surfaces after the base plates 1a are connected.

[0067] In addition, in order to make the free ends of the third buckle 13 and the fourth buckle 14 fit into the corresponding slots more smoothly, guide slopes can be provided on the first free end 131 of the third buckle 13 and the second free end 141 of the fourth buckle 14.

[0068] Furthermore, when a third buckle 13 and a fourth buckle 14 are provided on the same side wall of the base plate 1a, in order to ensure the stability of the buckles after they are engaged (they will not shift along the central axis of the slot) and the stability between them and the adjacent buckles, the sides of the projections of the third buckle 13 and the fourth buckle 14 on the same side wall of the base plate 1a abut against each other to achieve mutual positioning.

[0069] When a third buckle 13 and a fourth buckle 14 are provided on the same side wall of the base plate 1a, and the sum of the number of the third buckle 13 and the fourth buckle 14 is three or more, the third buckle 13 and the fourth buckle 14 are alternately arranged on the same side wall of the base plate 1a, which can ensure the connection stability of a pair of bearing plates.

[0070] like Figure 8As shown, in another embodiment, both the third buckle 13 and the fourth buckle 14 include a main body section and a snap-fit ​​section. Taking the fourth buckle 14 as an example, it includes a second main body section and a second snap-fit ​​section. The second main body section is integrally formed with the base plate 1a. Specifically, the second main body section includes a second connecting portion 14a and a second insert portion 14b formed on the second connecting portion 14a. The second snap-fit ​​section is made of hard plastic, which can be deformed by compression. It includes a second free end 141 and a second extension portion 14c. The second extension portion 14c is provided with a second slot (not shown). The second slot passes through... The second snap-fit ​​section is connected to the second main body section by an interference fit on the second insertion part 14b. This configuration forms the assembled structure of the fourth snap-fit ​​14. Because the second snap-fit ​​section is deformable, the aforementioned interference fit can be achieved. Similarly, the third snap-fit ​​13 has the same assembled structure, including a first main body section and a first snap-fit ​​section. The first main body section includes a first connecting part integrally formed with the base plate 1a and a first insertion part formed on the first connecting part. The first snap-fit ​​section includes a first free end 131 and a first extension part. A first slot on the first extension part is fitted onto the first insertion part. Before the third snap-fit ​​13 and the fourth snap-fit ​​14 on the two base plates 1a need to be engaged, the first extension part and the second extension part 14c are respectively interference-fitted onto the first insertion part and the second insertion part 14b to form complete third snap-fit ​​13 and fourth snap-fit ​​14. Then, the connection between a pair of adjacent base plates 1a can be achieved through the engagement of the first free end 131 and the second free end 141. By setting up a main body section and a snap-fit ​​section in the form of a plug-in assembly, after a carrier plate 10 is damaged, the third snap 13 and the fourth snap 14 can be separated by cutting the snap-fit ​​section (free end), thereby enabling the two carrier plates 10 to be separated after being misaligned in the vertical direction; when it is necessary to connect a pair of carrier plates 10, the snap-fit ​​engagement can be achieved by installing a new snap-fit ​​section on the main body section to re-form a complete third snap 13 and fourth snap 14.

[0071] Furthermore, to ensure the connection stability between the main body segment and the snap-fit ​​segment, a second protrusion 14d is provided on the second insertion portion 14b, and a second groove (not shown) is provided in the second slot. The connection stability between the second snap-fit ​​segment and the second main body segment is improved by the cooperation between the second protrusion 14d and the second groove. Figures 9 to 11As shown, to achieve precision and convenience in assembling a pair of support plates 10, limiting cylinders 151 are provided on both sides of one end of the extension plate 1b, and limiting grooves 152 are provided on both sides of the other end. The pair of limiting cylinders 151 are respectively embedded in the pair of limiting grooves 152 to rotatably connect one support plate 10 relative to the other support plate 10. During assembly, the limiting cylinder 151 on one support plate 10 to be installed is placed into the limiting groove 152 on another support plate 10 that has been positioned in the ditch. The cooperation between the limiting cylinder 151 and the limiting groove 152 serves as a pre-positioning and rotational support. Then, by rotating the support plate 10 to be installed, its bottom plate 1a is aligned with the bottom plate 1a on the already positioned support plate 10. At the same time (with the help of rotational force or external thrust), the third buckle 13 and the fourth buckle 14 are engaged, thus completing the assembly of the two support plates.

[0072] Furthermore, the end of the limiting cylinder 151 is provided with a limiting platform 1511, which can ensure that the position of the limiting cylinder 151 within the limiting groove 152 is stable.

[0073] In addition, when a pair of bearing plates 10 are connected by rotation using the limiting cylinder 151, a clearance notch 103 is provided on the side of the limiting cylinder 151 and the limiting groove 152 on the extension plate 1b, which can prevent the pair of bearing plates 10 from being unable to be pre-positioned in an angled state; a sealing plate 203 is provided on the side plate 20, and the sealing plate 203 is embedded in the clearance notch 103 after the pair of extension plates 10b abut against each other, ensuring aesthetics and sealing.

[0074] like Figures 12 to 13 As shown, the prefabricated ditch also includes a planting frame 30. The planting frame 30 includes at least a surrounding plate 31 and a limiting plate 32 disposed within the surrounding plate 31. The limiting plate 32 is provided with growth holes 320 for plants to pass through. The side plate 20 is provided with an installation opening 200. The planting frame 30 is embedded in the installation opening 200. The installation of the planting frame 30 can avoid the unsightly appearance caused by excessive exposure of the side plate when the water level in the ditch is low. Plants extending beyond the growth holes 320 on the planting frame 30 can enhance the aesthetic effect and also increase the ecological diversity in the ditch. In this embodiment, the planting frame 30 uses its growth holes 320 (such as small hole structures) to provide a passage for plants to pass through.

[0075] In the installation method of planting frame 30 and installation port 200, the surrounding plate 31 is provided with multiple wing plates 33, and the side plate 20 is provided with multiple pressure plates 211 located inside the installation port 200. At least part of the wing plates 33 are pressed down by the pressure plates 211 to abut the planting frame 30 against the ditch slope, which can prevent the planting frame 30 from detaching from the side plate 20 due to the impact of water flow or human factors. Furthermore, the side plate 20 is provided with anti-slip plate 212 located inside the installation port 200. At least part of the wing plates 33 abut against the anti-slip plate 212 to support the planting frame 30, which can prevent the planting frame 30 from sliding down / moving on the ditch slope and ensure the stability of the planting frame.

[0076] Furthermore, the wing plate 33 is provided with positioning holes 330, and the pressure plate 211 and anti-slip plate 212 are provided with positioning posts 210. The positioning holes 330 are fitted onto the positioning posts 210, which can ensure that the planting frame 30 is accurately positioned at the installation port 200 and is installed stably.

[0077] In another embodiment of the planting frame 30, it also includes a porous ribbed body 34, such as a sponge. The porous ribbed body 34 is snapped into the enclosure 31 and abuts against the limiting plate 32. Since the porous ribbed body 34 has a certain pore structure, it abuts against the ditch slope, allowing the plants on the ditch slope to pass through the porous ribbed body 34 and extend out of the growth hole 320. The porous ribbed body 34 has water storage and wave dissipation functions. The water flow in the ditch will not pass through the porous ribbed body and impact the ditch slope, which can ensure soil and water stability and avoid soil erosion.

[0078] Preferably, the planting frame 30 is provided with a baffle 35, which abuts against the side of the porous rib 34 away from the limiting plate 32, so that the porous rib 34 can be stably embedded into the planting frame 30, which facilitates transportation and installation.

[0079] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
