Description

Technical Field

[0001] The invention relates to the technical field of ditch devices, and in particular to an assembled ditch. Background Art

[0002] In order to facilitate the on-site assembly of ditches, prefabricated ditches are increasingly used in the prior art. Multiple prefabricated ditches are positioned and connected in sequence in the ditch slope. This not only makes the preparation and transportation of the ditches more convenient, but also makes the assembly of the ditches more efficient.

[0003] For example, the prefabricated ditch with application number 202022024719.2 discloses a prefabricated sheet pile body and ditch side plates, which are connected by mortise and tenon joints during assembly. The installation and fixing methods are simple, but it has two problems: on the one hand, there is no connection between adjacent units, which may cause lateral separation or dislocation between adjacent units; on the other hand, adjacent units cannot prevent vertical dislocation from each other, especially when the soil at the bottom of the ditch slope collapses or flows away, there will inevitably be a lack of support for the ditch structure, especially when the lack of support occurs at the connection between adjacent units, it is more likely to cause dislocation and unevenness, and one side of a unit may sink at the place where there is no support, causing the entire unit to produce a rotation-like phenomenon, then gaps will appear between adjacent units, which will not only cause unstable and uneven connections, but may also cause water in the ditch structure to seep into the ditch slope through the gaps, further aggravating soil erosion.

[0004] In addition to the above-mentioned structural defects, traditional prefabricated ditches are usually made of concrete or plastic. Concrete has a high density, which is not conducive to transportation and installation; the mechanical properties of plastic itself are very limited and it is easy to crack.

[0005] In view of this, the industry urgently needs to provide an assembled ditch that can be manufactured using a molding process and has a more stable and reliable structure. Summary of the invention

[0006] The object of the present invention is to provide an assembled ditch, wherein adjacent ditch plates can be prevented from being laterally separated or misaligned by the cooperation of the insert block and the slot in the lateral positioning mechanism, and the vertical misalignment between the ditch plates can be prevented by rotating the rotating block in the vertical positioning mechanism so that the positioning block is located between the lower plate and the upper plate, thereby ensuring the connection stability between adjacent ditch plates, and when the positioning groove on the positioning block cooperates with the stop block on the rotating block, the lateral separation between the bottom plates of the ditch plates can also be prevented, thereby improving the connection stability; at the same time, the assembled ditch of the present invention can be manufactured by a molding process, which can further improve its mechanical properties.

[0063] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0064] like Figures 1 to 4 As shown, an assembled ditch includes a ditch plate 10, and a vertical positioning mechanism 20 and a horizontal positioning mechanism 30 connecting two adjacent ditch plates 10, the horizontal positioning mechanism 30 includes a slot 31 and a plug plate 32, a pair of slots 31 are symmetrically arranged on one side of the side plate 1b of the ditch plate 10, and a pair of plug plates 32 are symmetrically arranged on the other side of the side plate 1b of the ditch plate 10, the slots 31 are embedded in the plug plates 32 to horizontally connect the pair of ditch plates 10, the vertical positioning mechanism 20 includes a positioning block 21 and a rotating block 22, and the ditch plate The bottom plate 1a of 10 is provided with clearance holes 100 on opposite sides, and the positioning block 21 is arranged on the side wall of the clearance hole 100. The rotating block 22 includes a central axis 221, a lower plate 222 and an upper plate 223. A pair of lower plates 222 are arranged at the lower part of the central axis 221 with a gap 2220 between them, and the upper plate 223 is arranged at the upper end of the central axis 221. When a pair of ditch plates 10 are laterally abutted, the rotating block 22 is arranged in a pair of clearance holes 100, and the positioning block 21 is embedded between the lower plate 222 and the upper plate 223.

[0065] In the present invention, when a ditch plate 10 to be assembled is combined with another ditch plate 10 already positioned on the ditch slope, the ditch plate 10 to be assembled is placed in the ditch slope from top to bottom so that the side walls of the two ditch plates 10 are abutted. During this process, a pair of plug plates 32 located on both sides of one ditch plate 10 are respectively embedded in the slots 31 on both sides of the other ditch plate 10. The slots 31 and the plug plates 32 cooperate to connect the pair of ditch plates 10 in the horizontal direction. After the pair of ditch plates 10 are abutted against each other, a pair of plug plates 32 are inserted into the slots 31 on both sides of the other ditch plate 10. The positioning holes 100 are connected to form an installation cavity 100a, and a pair of non-adjacent positioning blocks 21 are provided in the installation cavity 100a. The rotating block 22 is embedded in the installation cavity 100a, and the positioning block 21 is passed through the gap 2220 between the pair of lower plates 222, so that the height position of the positioning block 21 is located in the area between the lower plate 222 and the upper plate 223. The rotating block 22 is rotated (by rotating the upper plate 223) so that the positioning blocks 21 on the two ditch plates 10 are both positioned between the lower plate 222 and the upper plate 223, and the rotating block 22 is rotated (by rotating the upper plate 223). The plate 222 and the upper plate 223 limit the position of the pair of positioning blocks 21 so that the pair of positioning blocks 21 always remain in a flush state, thereby keeping a pair of adjacent ditch plates 10 in a flush state; further, in order to facilitate the rotation of the rotating block 22 relative to the positioning block 21 and limit the lateral movement of the rotating block 22 relative to the positioning block 21, the central axis 221 is set to a cylindrical structure, the cross-sections of the lower plate 222 and the upper plate 223 are respectively fan-shaped and circular, and the side wall of the positioning block 21 away from the clearance hole 100 is provided with a central axis that can accommodate The contoured arc surface 212 on the outside of the shaft 221; the present invention can prevent a pair of ditch plates 10 from being separated or misplaced in the lateral direction through the lateral positioning mechanism 30, and can prevent a pair of ditch plates 10 from being misplaced in the vertical direction through the vertical positioning mechanism 20. Even if the support for the bottom plate 1a of the ditch plate 10 is lost due to the collapse of the soil at the bottom of the ditch slope or soil erosion, the connection points of the adjacent pair of ditch plates 10 can still be stably connected to each other, thereby ensuring the connection stability between the adjacent ditch plates 10.

[0066] Regarding the setting of the transverse positioning mechanism 30, in one embodiment, a slot 31 is set on the ditch plate 10, and a hook (such as an L-shaped structure) on one end of the plug plate 32 extends out of the ditch plate 10, so that when the ditch plate 10 to be assembled is combined from top to bottom with another ditch plate 10 that has been positioned on the ditch slope, the hook on the plug plate 32 can be embedded in the slot 31 to achieve the connection and abutment between a pair of ditch plates 10. However, in the above-mentioned embodiment, the sealing effect between the pair of ditch plates 10 after abutment is not good, that is, the linear gap formed between the two after abutment is easy to seep water into the ditch slope. Therefore, in another embodiment, combined with Figure 1As shown, a backing plate 111 is provided on one side of the ditch plate 10, and a cover plate 112 is provided on the other side. When a pair of ditch plates 10 are in contact with each other, the cover plate 112 is in contact with the upper end of the backing plate 111, and a staggered gap is formed between the cover plate 112 and the backing plate 111 to achieve a good sealing effect. Furthermore, as shown in FIG. Figure 5 As shown in, a recess 1110 can be provided at the upper end of the pad 111, and a convex portion (not shown) matching the recess 1110 can be provided at the lower end of the cover 112. When the cover 112 abuts against the pad 111, the convex portion is embedded in the recess 1110, which can form a better sealing effect on the one hand, and improve the connection stability between the cover 112 and the pad 111 on the other hand; based on the premise that the pad 111 and the cover 112 are provided on the ditch plate 10, the plug plate 32 can be provided at the lower end of the cover 112, and the slot 31 can be provided on the pad 111, which can not only ensure the lateral connection of a pair of ditch plates 10, but also improve the sealing between the two, and facilitate the molding of the ditch plate 10 structure (such as molding the ditch plate 10 by molding, and molding the pad 111 and the cover 112 on both sides of the ditch plate 10, and molding the slot 31 and the plug plate 32 on the pad 111 and the cover 112 respectively).

[0067] like Figure 5 and Figure 7 As shown, in an embodiment related to the positioning block 21 and the rotating block 22, a positioning groove 211 is provided on the positioning block 21, and the positioning groove 211 is an arc-shaped structure and opens upward. A stopper 224 matching the positioning groove 211 is provided at the lower end of the upper plate 223. When the rotating block 22 is rotated so that the positioning block 21 is embedded between the lower plate 222 and the upper plate 223, a pair of stops 224 on the rotating block 22 are respectively embedded in the positioning grooves 211 on the positioning block 21 on an adjacent pair of ditch plates 10, which can prevent the pair of ditch plates 10 from lateral separation at this position. Therefore, in this embodiment, the lateral separation and vertical dislocation of a pair of ditch plates 10 at this position can be achieved through the cooperation of the rotating block 22 and the positioning block 21; when a pair of ditch plates 10 are connected by a vertical positioning mechanism 20 and two lateral positioning mechanisms 30, the three-point connection can improve the connection stability.

[0068] Furthermore, a block 2111 having an arc surface structure is provided in the positioning groove 211, and a slot 2241 is provided on the stopper 224. When the stopper 224 is embedded in the positioning groove 211, the block 2111 is embedded in the slot 2241, which can ensure the installation stability of the rotating block 22 on the positioning block 21.

[0069] Continue as Figure 6As shown, in another embodiment related to the positioning block 21, the difference is that the clamping block 2111 is arranged on the side wall of the positioning groove 211 in a vertical structure, and the clamping groove 2241 should also be arranged on the side wall of the stopper 224 in a vertical structure. In addition, a stopper plate 2112 is provided at the rotation end of the stopper 224 in the positioning groove 211, which can prevent the stopper 224 from being unable to be fully embedded in the positioning groove 211 after excessive rotation; a tightening structure can also be provided at the rotation end of the stopper 224 in the positioning groove 211, and the tightening structure can be a tightening arc surface 2113 formed on the side wall of the positioning groove 211. When the stopper 224 rotates to the tightening arc surface 2113, the narrowing of the positioning groove 211 can make the rotating block 22 play a role of lateral pulling on the positioning block 21, so that a pair of adjacent positioning blocks 21 (ditch plates 10) fit more closely.

[0070] Preferably, when the rotating block 22 is disposed in the installation cavity 100a, the projections of the positioning block 21 and the lower plate 222 along the central axis direction of the central axis 221 coincide with each other, thereby ensuring the effectiveness of the lower plate 222 limiting the positioning block 21, and the upper end surface of the upper plate 223 of the cylindrical structure is flush with the side of the ditch plate 10 away from the ditch slope, thereby achieving the flatness of the ditch plate 10 and the sealing of the upper plate 223 to the installation cavity 100a.

[0071] After the ditch is installed in the ditch slope, the ideal state is that the water flows in the ditch, but it is inevitable that water will exist between the ditch and the ditch slope. In this case, if the liquid level in the ditch is higher than the liquid level outside the ditch, the pressure difference can ensure the stability of the ditch in the ditch slope, but if the liquid level in the ditch is lower than the liquid level outside the ditch, it may cause the ditch to float and become unstable. To solve the above problems, Figure 8 As shown, in one embodiment, the rotating block 22 is provided with a middle hole 220 penetrating the body thereof, and an anchor rod 25 is arranged in the middle hole 220 for extending into the ditch slope, so that the rotating block 22 and the ditch plate 10 can be fixed in the ditch slope. Although this method ensures the stability of the ditch, the water outside the ditch always forms a large buoyancy on the ditch. The long-term inability to drain water can only cause the water to infiltrate into the ditch slope, which may cause soil loosening or soil erosion. Therefore, Figures 9 to 12As shown, in another embodiment, similarly, the rotating block 22 is provided with a middle hole 220 passing through its body, preferably the middle hole 220 passes through the upper plate 223 and the central axis 221, and a positioning member 23 and a plug 24 are provided in the middle hole 220. The positioning member 23 can be integrally formed with the rotating block 22, that is, it is fixed in the middle hole 220, and a first through hole 2301 and a second through hole 2302 are provided on the body of the positioning member 23, and / or between its body and the side wall of the middle hole 220, the plug 24 passes through the first through hole 2301, and a connecting rod 242 is formed in the first through hole 2301, and an upper baffle 241 and a lower baffle 243 are respectively formed at the upper end and the lower end of the connecting rod 242, the upper baffle 241 covers the middle hole 220, and the lower baffle 243 does not cover the second through hole 2402, and the plug 24 opens the middle hole 220 after moving up. Based on the above arrangement, when the liquid level in the ditch is higher than the liquid level outside the ditch, or there is no water outside the ditch, the pressure exerted by the water in the ditch on the upper baffle plate 241 can cause the plug 24 to block the middle hole 220 to prevent the water from flowing out of the ditch; when the liquid level in the ditch is lower than the liquid level outside the ditch, the upward buoyancy of the water outside the ditch on the plug 24 is greater than the downward pressure exerted by the water in the ditch, so the plug 24 (specifically the upper plate 241) is affected by the buoyancy of the water that enters through the bottom of the middle hole 220 and passes through the second through hole 2302. The force causes the upper plate 241 to be pushed upward to open the middle hole 220, allowing water outside the ditch to enter the ditch through the middle hole 220, and because the lower baffle 243 is blocked by the first perforation 2031, the plug 24 cannot be separated from the middle hole 220. The above-mentioned water flow effect at least makes the liquid levels inside and outside the ditch the same, and the water outside the ditch simultaneously diffuses to the ditch slope and other factors eventually make the liquid level in the ditch higher than the liquid level outside the ditch, and the plug 24 is pressed down again to block the middle hole 220, thereby ensuring the stability of the ditch.

[0072] Specifically, the positioning member 23 includes a center ring 231 and a plurality of connecting rods 232 arranged on the outer side wall of the center ring 231. The other ends of the plurality of connecting rods 232 are respectively fixedly connected to the side walls of the middle hole 220. A first through hole 2301 is formed on the center ring 231, and a second through hole 2302 is formed between adjacent connecting rods 232. In one embodiment, the plug 24 can be an elastic member of an integral structure, one end of which passes through the first through hole 2301 after being squeezed and deformed, and forms a connecting rod 242 located in the first through hole 2301 after being deformed and restored, and a second through hole 2302 is formed below the first through hole 2301. The lower baffle 243 is formed, and the upper baffle 241 is formed above the first through hole 2301. The plug 24 is limited on the positioning member 23 by the action of the upper baffle 241 and the lower baffle 243. When the upward buoyancy of the upper baffle 241 is greater than the pressure of the water in the ditch, the buoyancy of the water acting on the lower end of the upper baffle 241 will cause the upper baffle 241 to pull the connecting rod 242 upward, thereby opening the second through hole 2302, and the water will enter the ditch. When the upward buoyancy of the upper baffle 241 is smaller, the connecting rod 242 disappears and the upper baffle covers the second through hole 2302. Fig.11 As shown, the plug block 24 is a hard part, which is assembled and formed, such as the upper baffle 241 and the connecting rod 242 are an integrated structure. After the connecting rod 242 passes through the first through hole 2301, the lower baffle 243 is installed on the lower end of the connecting rod 242, such as a nut screwed on the connecting rod. In this setting, in order to realize that the upper baffle 241 can move upward and open the second through hole, the length of the connecting rod 242 needs to be greater than the height of the first through hole 2301. Since the connecting rod 242 is a hard part, the upper baffle 241 can only rely on its own gravity or the water in the ditch is large. The pressure will re-cover the second through-hole 2302. Therefore, to ensure that the upper baffle 241 can be smoothly reset, a spring 244 is sleeved on the connecting rod 242. The upper and lower ends of the spring 244 are respectively in contact with the positioning member 23 and the lower baffle 243. When the upper baffle 241 moves up to open the second through-hole 2302, the lower baffle 243 compresses the spring 244. When the buoyancy of the upper baffle 241 is small, the elastic recovery process of the spring 244 can drive the lower baffle 243 and the connecting rod 242 to move downward, so that the upper baffle 241 covers the second through-hole 2303.

[0073] Preferably, a concave cavity 2231 is provided on the upper end surface of the upper plate 223, and the upper baffle 241 is embedded in the concave cavity 2231 and can be flush with the upper end surface of the upper plate 223, which can ensure the flatness of the inner wall of the ditch on the one hand, and form a better sealing effect on the other hand; in addition, a first inclined abutting surface 223a is provided on the side wall of the concave cavity 2231, and a matching second inclined abutting surface 241a is provided between the side walls of the upper baffle 241. The setting of the two inclined abutting surfaces can ensure the sealing effect while also facilitating the formation of a bottom-up flaring structure. When the liquid level outside the ditch is higher than the liquid level inside the ditch, it is beneficial for the water body to push up the plug 24 and then flow into the ditch.

[0074] Preferably, a porous rib-shaped elastic body, such as a sponge, is provided in the middle hole 220 below the positioning member 23 and the plug 24 to prevent the soil in the ditch slope from blocking the middle hole 220 upward.

[0075] Combination Figure 4 and Fig.13 As shown, in order to facilitate the operation of the rotating block 22 to rotate in the installation cavity 100a, the upper end surface of the upper plate 223 is provided with a socket 2230 for the knob 50 to be inserted into and drive the upper plate 223 to rotate. For example, when the socket 2230 is a circular structure and there are multiple of them, the knob 50 includes a rotating plate 51, a plug 52 and a gripping portion 53, the gripping portion 53 is arranged at the upper end of the rotating plate 51, and multiple plugs 52 with cylindrical structures are arranged at the lower end of the rotating plate 51, and the plugs 52 are correspondingly embedded in the socket 2230, and the rotating block 22 is driven to rotate by holding the gripping portion 53; for another example, when the socket 2230 is a non-circular structure, the knob can be a straight plate structure, and the lower end of the straight plate structure is embedded in the socket 2230, and the rotating block 22 is driven to rotate by rotating the knob.

[0076] For example Figure 3 As shown, the ditch plate 10 is an integrally formed structure formed by molding, which includes a bottom plate 1a and side plates 1b located on opposite sides of the bottom plate 1a, and the side plates 1b include an extension plate 1b′ and a fin plate 1b″, the extension plate 1b′ is connected to the bottom plate 1a, the fin plate 1b″ is arranged at the upper end of the extension plate 1b′, and the transverse positioning mechanism 30 is formed on the fin plate 1b″, and the horizontal structure of the fin plate 1b″ is used to facilitate the molding of the slot 31 and the plug plate 32 during molding. Similarly, the positioning hole 100 and the positioning block 31 are formed on the bottom plate 1a of the horizontal structure, which is also convenient for molding; in addition, a plurality of reinforcing ribs 1c can be formed on one side of the ditch plate 10 close to the ditch slope during the molding process to improve the structural strength of the ditch plate 10.

[0077] like Figures 14 to 17As shown, in order to improve the ecology of the ditch plate 10 installed in the ditch slope so that the ditch can have a better landscape effect when the liquid level is low, an ecological frame 40 can also be set in the ditch, that is, a mounting hole 101 is set on the ditch plate 10 and / or the rotating block 22, and the ecological frame 40 is connected to the ditch plate 10 and is located in the mounting hole 101.

[0078] like Fig.14 and Fig.15 As shown, in one installation method of the eco-frame 40, if the eco-frame 40 is a square structure, the mounting hole 101 is also a square structure, support plates are respectively provided on the two opposite inner walls of the mounting hole 101, namely, a first support plate 121 and a second support plate 122, and limiting grooves are respectively provided on the two opposite side walls of the eco-frame 40, namely, a first limiting groove 411 and a second limiting groove 412. The first support plate 121 is embedded in the first limiting groove 411, and the second support plate 122 is embedded in the second limiting groove 412 to position the eco-frame 40 in the mounting hole 101. The premise of this installation method is that the height position of the first support plate 121 in the installation hole 101 is not lower than the height position of the second support plate 122. For example, when the installation hole 101 is formed on the side plate 1b (extension plate 1b″), the height position of the first support plate 121 is higher than the height position of the second support plate 122. The specific method of this installation method is: align the first limiting groove 411 with the first support plate 121, and embed the first support plate 121 into the first limiting groove 411 by moving the ecological frame 40 obliquely upward. When the first support plate 121 is completely embedded in the first limiting groove 411, adjust the ecological frame 40 so that the opening of the second limiting groove 412 is aligned with the second support plate 122, and at least partially embed the second support plate 122 into the second limiting groove 412 by moving the ecological frame 40 obliquely downward. The depth of the first limiting groove 411 is set to be greater than the length of the first support plate 121. Although the eco-frame 40 moves diagonally downward for a certain distance, the first limiting groove 411 is still nested on the first support plate 121 at least near the outer side. Therefore, the first support plate 121 and the first support plate 122 are respectively embedded in the first limiting groove 411 and the second limiting groove 412 to support and limit the eco-frame 40; similarly, if the eco-frame 40 needs to be removed from the mounting hole 101, the second limiting groove 412 can be disengaged from the second support plate 122 by first moving the eco-frame 40 diagonally upward, and then the eco-frame 40 can be adjusted to misalign the second limiting groove 412 and the second support plate 122, and then the eco-frame 40 can be moved diagonally downward to disengage the first limiting groove 411 from the first support plate 121, and then the eco-frame 40 can be taken out.

[0079] In this installation method, a positioning plate 131 can also be respectively set on the other two inner walls of the installation hole 101, and a first groove 421 is respectively set at the lower part of the other two side walls of the ecological frame 40, and a first baffle 422 is set at the lower part of one side of the first groove 421. The positioning plate 131 is embedded in the first groove 421 and moved through the ecological frame 40 so that the positioning plate 131 abuts against the upper end of the first baffle 422. Specifically, after the first support plate 121 is embedded in the first limiting groove 411, and when the opening of the second limiting groove 412 is adjusted to be aligned with the second support plate 122, the first groove 421 moves downward relatively and is sleeved on the positioning plate 131. During the process of the ecological frame 40 moving obliquely downward, the first baffle 422 moves to the upper end of the positioning plate 131 and abuts against the positioning plate 131. Therefore, the cooperation between the positioning plate 131, the first groove 421 and the first baffle 422 can make the ecological frame 40 more stably installed.

[0080] In order to avoid instability caused by the first baffle 422 only being able to abut against one side of the positioning plate 131, a first gap 420 is provided between the first baffle 422 and the side wall of one side of the first groove 421. When the positioning plate 131 abuts against the inner wall of the first groove 421, the first baffle 422 can abut against the middle position of the positioning plate 131. It should be noted that when the eco-frame 40 is molded, a first clearance hole 423 is provided on the eco-frame 40 above the first baffle 422. The formation of the first clearance hole 423 during molding is due to the existence of a structure for molding the first baffle 422 in the mold, that is, the existence of this structure in the mold makes it inevitable to form the first clearance hole 423 on the eco-frame 40.

[0081] like Fig.16 and Fig.17 As shown, in another installation method of the eco-frame 40, if the eco-frame 40 is a circular structure, the mounting hole 101 is also a circular structure, the mounting hole 101 is formed on the ditch plate 10, and a second groove 4101 is provided at the lower part of the side wall of the eco-frame 40, and a second baffle 4102 is provided at the lower part of one side of the second groove 4101, and the second baffle 4102 is arranged in the second groove 4101 to form a limiting groove 41, and the support plate 12 on the inner wall of the mounting hole 101 is embedded in the second groove 4101 and rotated through the eco-frame 40 to abut against the upper end of the second baffle 4102. When the mounting hole 101 is formed on the side panel 1b (extension panel 1b″), the specific method of this installation is: adjust the eco-frame 40 to be parallel to the side panel 1b, and align the positions of a pair of second grooves 4101 that do not have a second baffle 4102 with a pair of support plates 12 respectively; after the eco-frame 40 moves, the second grooves 4101 are sleeved on the support plates 12; and after the eco-frame 40 rotates, the second baffle 4102 is located at the lower end of the support plate 12 to position the eco-frame 40 in the mounting hole 101.

[0082] There is a second gap 4100 between the second baffle plate 4102 and the side wall of the second groove 4101. When the support plate 12 abuts against the inner wall of the second groove 4102, the second baffle plate 4102 can abut against the middle position of the support plate 12 to maintain stability; when the ecological frame 40 is molded, a second clearance hole 4103 is provided on the ecological frame 40 above the second baffle plate 4102. Similarly, the existence of the structure for forming the second baffle plate 4102 in the mold makes it inevitable to form a second clearance hole 4103 on the ecological frame 40.

[0083] In another installation method of the eco-frame 40, the eco-frame 40 is a circular structure, the mounting hole 101 is also a circular structure, and the structure inside the mounting hole 101 is also the same, but the mounting hole 101 is not formed on the ditch plate 10, but formed on the rotating block 22 (the structure on the outer side of the rotating block 22 remains unchanged), so that the rotating block 22 can serve as a connecting structure for a pair of ditch plates 10 and as a carrier of the eco-frame 40. It should be noted that in order to match the size of the eco-frame 40, the size of the rotating block 22 and the size of the clearance hole 100 on the ditch plate 10 in this embodiment need to be adaptively adjusted.

[0084] The above-mentioned ecological frame 40 may be merely a frame structure with a through-hole structure 400, which is used for plants on the ditch slope to extend into the ditch. A porous rib-like elastic body (such as a sponge) may also be provided at the lower end of the frame structure by interference fit or the like. The porous rib-like elastic body covers the through-hole structure 400, which allows branches and leaves of plants to pass through, but the (intricate) roots of the plants cannot pass through and escape from the ditch slope and the porous rib-like elastic body, thereby ensuring that the plants are stably planted in the ditch slope.

[0085] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
