Description
Technical Field
[0001] This utility model relates to the technical field of ecological frames, and in particular to a prefabricated ecological frame and a embankment structure having the ecological frame. Background Technology
[0002] In the field of river management and bank protection engineering, traditional bank protection projects generally adopt forms such as cast-in-place concrete, masonry blocks, and gabions, and mainly use rigid materials such as cement, asphalt, and concrete as building materials. This traditional bank protection method has significant drawbacks. It alters the natural state of the original river boundary, damages the natural ecological environment, and severs the close connection between the original river water and soil, weakening the energy flow in the ecosystem, thus adversely affecting the entire river ecosystem. To address the aforementioned issues, existing technologies propose a scheme for forming riverbank protection using ecological frames. This scheme aims to achieve a close connection between the river water and the soil. It utilizes the splicing and joining of ecological frames to construct a tiered structure, enabling it to adapt to diverse shoreline morphologies in an efficient and flexible manner. However, the existing technical solutions still have room for improvement. The existing ecological frames lack effective connection designs between adjacent ecological frames and between the tiered upper and lower ecological frame structures, resulting in certain deficiencies in maintaining ecological balance and ensuring structural stability, making it difficult to fully meet the dual requirements of modern revetment engineering for both ecological sustainability and stability.
[0003] In view of this, the inventor has specifically designed a prefabricated ecological frame and a embankment structure having the ecological frame, which leads to this invention. Utility Model Content
[0004] To solve the above problems, one of the technical solutions of this utility model is as follows: A prefabricated ecological frame and a revetment structure having the ecological frame are disclosed. The frame includes a frame body, a front panel, a rear panel, and side panels connected to both sides. The front panel, rear panel, and side panels are arranged to form an ecological groove that runs vertically through the frame. The side panels on both sides are arranged to form connecting slots along the height direction of the frame. The connecting slots between adjacent frames can be joined to form connecting holes distributed along the contact line of adjacent frames. The upper and lower connecting slots of the frame along the height direction are both recessed inward to form limiting grooves that conform to their shape.
[0005] Preferably, the front panel and the rear panel are both arc-shaped and distributed in parallel around the same center, and the two side panels are radially symmetrically distributed along the center of the front panel and the rear panel so that the frame as a whole forms a fan shape.
[0006] Preferably, the central angles corresponding to the front panel and the rear panel are 25°.
[0007] Preferably, the connecting slot includes two semi-circular side slots distributed along the edge of the side plate and a straight wiring slot connecting the two side slots.
[0008] Preferably, when two adjacent frames are joined together, the two side grooves and wiring grooves are joined together to form a waist shape.
[0009] Preferably, the wiring groove is located at the center of the side plate, and the two side grooves are symmetrically distributed about the wiring groove.
[0010] The second technical solution of this utility model is as follows: A levee protection structure includes prefabricated ecological frames stacked in a staggered manner.
[0011] Preferably, the ecological frames are spliced together in alternating directions or in the same direction.
[0012] Preferably, the structure also includes a buried stone concrete foundation, a plain concrete cushion layer, a riprap toe protection layer, backfill material, geotextile, and a crushed stone filter layer. The riprap toe protection layer and the buried stone concrete foundation are placed on the plain concrete cushion layer. The ecological frames are stacked in a staggered manner on the upper side of the buried stone concrete foundation. The crushed stone filter layer is placed between the ecological frames and the riverbank soil. The geotextile is placed between the ecological frames and the buried stone concrete foundation, between the stacked ecological frames, and between the ecological frames and the crushed stone filter layer.
[0013] The beneficial effects of this utility model are: This utility model uses connecting slots on both sides of the frame to form a complete connecting hole at the contact position when adjacent frames are assembled. Thus, when the frames are stacked, only the positions of the two connecting holes need to partially overlap, and bolts for connection and fixation can be inserted between the two connecting holes to connect and fix the stacked frames. While using the ecological frame to improve the ecology, it can also improve the stability of the bank protection project.
[0014] The limiting groove can be used to hide the bolts used for connection, so as to avoid affecting the flatness of the splicing between adjacent frames.
[0015] In addition, the concentrically distributed arc-shaped front and rear panels allow for easy splicing of adjacent frames on the same horizontal plane, enabling alternating or unidirectional splicing to adapt to revetment construction of different shapes.
[0016] In particular, this invention reconstructs the revetment structure using stacked frames. Compared to traditional revetment projects, this arc-shaped prefabricated ecological frame, with its modular and prefabricated features, offers high efficiency and flexibility during construction. Innovative splicing technology enables diverse shoreline adaptations; continuous forward splicing creates smooth curves, while alternating forward and reverse splicing extends straight shorelines. Only a single-size ecological frame is needed to meet the construction requirements of complex shorelines. This provides a reference and model for similar revetment projects with wide construction areas and high ecological landscape requirements. Attached Figure Description

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example 1
[0021] Please see Figures 1 to 6 This is a prefabricated ecological frame and a embankment structure having the ecological frame, which is the preferred embodiment of the present utility model. The frame includes a frame 100, the frame 100 having a front panel 110, a rear panel 120 and side panels 130 connected to both sides, and the front panel 110, the rear panel 120 and the side panels 130 are enclosed to form an ecological trough 140 that runs vertically through the structure.
[0022] Specifically, in this embodiment, the front panel 110 and the rear panel 120 of the frame 100 are both arc-shaped and distributed in parallel in the same direction around the same center. The two side panels 130 are radially symmetrically distributed along the center of the front panel 110 and the rear panel 120 so that the cross-section of the frame 100 forms a fan shape as a whole.
[0023] Specifically, the central angles corresponding to the front panel 110 and the rear panel 120 are 25°.
[0024] Therefore, combined Figure 5 , 6 The aforementioned frame structure 100 with a specific central angle can be continuously spliced in the forward direction to form a smooth turning arc, and can be spliced alternately in the forward and reverse directions to extend a straight shoreline, making their coordination more flexible and varied.
[0025] The ecological trough 140 is used to fill the corresponding filler, such as backfill planting soil or backfill boulders and gravel, with a boulders:gravel ratio of 3:1. The backfill planting soil allows for the planting of corresponding ecological plants within the ecological frame, enhancing the integration between the revetment and the water body. The backfill boulders and gravel can form an exchange channel between the revetment and the water body. In the above case, the frame 100 with backfill planting soil should be stacked on top of the frame 100 with backfill boulders and gravel.
[0026] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the two side plates 130 extend through the frame 100 to form a connecting slot 200. The connecting slots 200 between adjacent frames 100 can be combined to form connecting holes 400 distributed along the contact line of adjacent frames 100.
[0027] In this embodiment, the connecting slot 200 includes two semi-circular side slots 210 distributed along the edge of the side plate 130 and a straight wiring slot 220 connecting the two side slots 210. When two adjacent frames 100 are assembled, the two side slots 210 and the wiring slot 220 are assembled to form a waist shape.
[0028] Therefore, combined Figure 4 When the upper and lower frames 100 are stacked, simply align the waist-shaped connecting holes 400 to form connecting channels distributed along the connecting holes 400 between the four adjacent frames 100. At this time, simply pass through a specially sized bolt 500 and use the corresponding nut 510 to pull and lock the four adjacent frames 100 in the vertical direction, thereby enhancing the stability of the structure.
[0029] Combination Figure 5 , 6 Due to the fan-shaped shape of the frame 100, when one of the connecting holes 400 is aligned with the connecting hole 400 on its lower side, the adjacent connecting holes 400 on its periphery often cannot be aligned. However, since the frame 100 has a certain regularity when it is assembled in the horizontal direction, after a certain number of connecting holes 400, the next set of vertically aligned connecting holes 400 will appear. By tightening and fixing these vertically aligned connecting holes 400, the connection between the upper and lower frames 100 can also be strengthened.
[0030] like Figure 1 , 2 As shown in Figure 3, the wiring groove 220 is located at the center of the side plate 130, and the two side grooves 210 are symmetrically distributed about the wiring groove 220. Thus, when adjacent frames 100 are spliced in the same direction or in a staggered manner, the connecting hole 400 is formed at the center of the edge of the side plate 130, so that the frames 100 can smoothly achieve both staggered splicing and same-direction splicing.
[0031] like Figure 2 As shown, the upper and lower connecting slots 200 of the frame 100 along the height direction are both recessed inward to form a limiting slot 300 that conforms to its shape.
[0032] In this embodiment, the shape of the limiting groove 300 makes the overall shape of the adjacent frame 100 conform to the waist shape of the connecting hole 400 when the adjacent frame 100 is assembled. This part serves as a countersunk hole, so that the bolts 500 and nuts 510 used to connect the adjacent frame 100 stacked on the upper and lower sides are hidden in the limiting grooves 300 on the upper and lower sides, so as to avoid affecting the stacking process between the frame 100. Example 2
[0033] A type of embankment structure, such as Figure 7As shown, it includes prefabricated ecoframes as in Example 1, with the ecoframes stacked in a staggered manner.
[0034] Preferably, the ecological frames are spliced together in alternating directions or in the same direction.
[0035] Preferably, the structure also includes a buried stone concrete foundation 610, a plain concrete cushion layer 600, a riprap toe protection 620, backfill material 630, geotextile 640, and a crushed stone filter layer 650. The riprap toe protection 620 and the buried stone concrete foundation 610 are placed on the plain concrete cushion layer 600. The ecological frames are stacked in a staggered manner on the upper side of the buried stone concrete foundation 610. The crushed stone filter layer 650 is placed between the ecological frames and the riverbank soil. The geotextile 640 is placed between the ecological frames and the buried stone concrete foundation 610, between the stacked ecological frames, and between the ecological frames and the crushed stone filter layer 650.
[0036] Specifically, the ecological frame is stacked to a height of 2m with a slope of 1:0.3. The embedded stone concrete foundation 610 is made of C30 concrete and is 1.5m thick. An installation groove 611 is formed by recessing the upper surface of the embedded stone concrete foundation 610. A wall toe (not shown in the figure) is formed on the front side of the installation groove 611, with a width of 0.5m and a protrusion of 0.3m. A wall heel (not shown in the figure) is formed on the rear side of the installation groove 611, with a width of 0.3m. A C15 plain concrete pad 6 is placed under the embedded stone concrete foundation 610. The retaining wall foundation is 100mm thick; the first-stage frame 100's ecological trough 140 is backfilled with boulders and crushed stone (boulders:crushed stone = 3:1), and the second-stage frame 100's ecological trough 140 is backfilled with planting soil; a layer of geotextile 640 with a specification of 500m2 / g is laid behind the wall and at the bottom of the frame 100; a crushed stone filter layer 650 with a thickness of 0.3m is set behind the wall; an expansion joint is set every 15m of the retaining wall foundation, with a joint width of 20mm, and the entire cross-section of the joint is filled with asphalt fir board. The backfill soil 660 behind the wall is excavated sandy soil, which should be compacted in layers, with each layer not exceeding 0.3m in thickness, and the relative density of the backfill soil ≥0.60.
[0037] The beneficial effects of this utility model are: This utility model uses connecting slots 200 on both sides of the frame 100 to form a complete connecting hole 400 at the contact position when adjacent frames 100 are spliced together. Thus, when the frames 100 are stacked, only the positions of the two connecting holes 400 need to partially overlap, and bolts 500 for connection and fixation can be inserted between the two connecting holes 400 to connect and fix the stacked frames 100. While using the ecological frame to improve the ecology, it can also improve the stability of the bank protection project.
[0038] The limiting groove 300 can be used to hide the bolts 500 used for connection, so as to avoid affecting the flatness of the splicing between the upper and lower adjacent frames 100.
[0039] Furthermore, the concentrically distributed arc-shaped front panel 110 and rear panel 120 enable adjacent frames 100 on the same horizontal plane to be easily spliced together, achieving alternating splicing or splicing in the same direction, adapting to revetment construction of different shapes.
[0040] In particular, this utility model reconstructs the revetment structure using stacked frames 100. Compared to traditional revetment projects, this arc-shaped prefabricated ecological frame, with its modular and prefabricated characteristics, offers high efficiency and flexibility in construction. Through innovative splicing technology, it achieves diverse shoreline adaptations. Continuous forward splicing creates smooth curves, while alternating forward and reverse splicing extends straight shorelines. Only a single-size ecological frame is needed to meet the construction requirements of complex shorelines. This provides a reference and model for similar revetment projects with wide construction areas and high ecological landscape requirements.
[0041] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
