Description

Technical Field

[0001] The utility model relates to the field of ecological revetments, and specifically to a protection structure for an ecological revetment. Background Technique

[0002] An ecological revetment is a form of revetment that combines ecological engineering and civil engineering technologies, which plays an important role in protecting the stability of the bank slope structure and maintaining the sustainable development of the river ecological environment. The construction of the ecological revetment will endow the riverbank ecosystem with multiple functions such as soil and water conservation, runoff regulation, water source conservation, water purification, and providing habitats for organisms. The design of the revetment project should be overall considered and reasonably arranged. Under the conditions of meeting the structural safety and not being severely scoured, it is advisable to adopt a combination of engineering measures and biological measures for protection.

[0003] According to the Chinese patent with the publication number CN218757286U, a protective ecological revetment structure is disclosed. By setting a protection component, the problem that the soil is loosened and lost and the roots of plants are loosened due to excessive water flow impact force is effectively avoided. With the cooperation of the fixing ring and the brush, the water flow can be buffered to avoid the water flow directly impacting the plants and causing the instability of the roots of the plants.

[0004] Regarding the above-mentioned disclosed patent content, when a large amount of water scours the revetment body, the plants can be irrigated through the water inlets, thus effectively avoiding excessive water flow impact force. However, the water inlets are equally distributed on the revetment, resulting in gaps between the water inlets, making it difficult for most of the water to enter the water inlets. As a result, most of the water flow will directly impact the revetment, and the revetment is composed of sand, gravel, soil, etc., making the anti-impact effect of the revetment poor, thereby reducing the protection performance of the revetment. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a protection structure for an ecological revetment to solve the technical problem of poor anti-impact effect of the revetment.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A protection structure for an ecological revetment, including a base layer and the ground. A plurality of pine piles are provided on the base layer, and a graded gravel layer is paved on the top of the pine piles. A stone chip layer is paved on the top of the graded gravel layer. A plurality of ecological frames are provided on the top of the stone chip layer. Two positioning columns are provided at the bottom of the ecological frame, and two positioning holes are provided at the top of the ecological frame. A backfill soil layer is paved on the ground. Threaded holes are opened on one side of the top of the ecological frame and above one side of the ecological frame, and fastening bolts are threadedly connected inside the threaded holes. A reinforcing plate is installed between every two of the fastening bolts.

[0007] By adopting the above technical solution, when stacking the ecological frames, the positioning columns at the bottom of the ecological frames need to be inserted into the positioning holes, so as to facilitate the positioning of the ecological frames and prevent the ecological frames from being misaligned during the stacking process, which may affect the stacking effect.

[0008] Furthermore, a gravel sand layer is filled between the backfill soil layer and the ecological frame.

[0009] By adopting the above technical solution, the setting of the gravel sand layer can improve the protection effect on the revetment.

[0010] Furthermore, an opening is provided on the side wall of the ecological frame, and the length and width of the opening are 1.8 m and 2 cm respectively.

[0011] By adopting the above technical solution, the reserved opening can meet the growth space of plant roots, achieve the anti-scouring effect and also take into account the ecological effect.

[0012] Furthermore, the dimensions of the length, width and height of the ecological frame are 2000×1000×500 mm, and the ecological frame is filled with planting soil.

[0013] By adopting the above technical solution, the setting of the ecological frame can improve the protection effect on the revetment.

[0014] Furthermore, the arrangement spacing of the pine wood piles is 500 mm on average.

[0015] By adopting the above technical solution, the setting of the pine wood piles can improve the bearing capacity of the ecological frame and avoid the problem of uneven settlement after the installation of the ecological frame.

[0016] Furthermore, the thickness of the graded gravel layer is 300 mm, and the thickness of the stone chip layer is 100 mm.

[0017] By adopting the above technical solution, the graded gravel layer and the stone chip layer can serve as the foundation of the ecological frame to facilitate the support of the ecological frame.

[0018] Furthermore, the positioning column is located inside the positioning hole, and the positioning column is adapted to the positioning hole.

[0019] By adopting the above technical solution, after the positioning column is moved into the positioning hole, the ecological frame can be positioned, which is convenient for stacking the ecological frames.

[0020] Furthermore, the reinforcing plate is detachably connected to the ecological frame through fastening bolts.

[0021] By adopting the above technical solution, it is convenient to disassemble and assemble the reinforcing plate through the fastening bolts, and the reinforcing plate can play a role in strengthening the ecological frame.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] 1. The ecological frame of the present utility model adopts a superimposed installation method, which can improve the waterproof flow impact effect of the revetment. And on the basis of meeting the basic condition of anti-scour weight, planting soil is filled in the ecological frame for planting aquatic plants, etc., and openings are reserved on the side and bottom of the ecological frame to meet the growth space of plant roots, achieving both the anti-scour effect and the ecological effect.
