AI Technical Summary
The bank protection structures for small and medium-sized rivers are insufficient in balancing flood control and ecological aesthetics. Existing technologies are unable to meet the requirements of both flood control and ecological aesthetics simultaneously, especially since existing bank protection structures are less effective in creating ecological aesthetics in areas that do not frequently experience floods.
The project adopts a combination of concrete toe protection and hydraulic and aquatic ecological structural sections. The hydraulic structural section includes a compacted base layer, a gravel cushion layer, and a concrete panel layer. The aquatic ecological structural section includes a compacted base layer, a gravel cushion layer, a topsoil layer, and a grass paver layer. The sections are connected by locking stones and foot stones. Square frame beams are installed on the outside of the grass pavers to enhance stability. Pedestrian railings and passageways are installed on the top of the bank.
It achieves the effect of both flood control and ecological beauty in the bank protection structure of small and medium-sized rivers. The hydraulic structure section reduces the roughness of the river channel, the water ecological structure section improves the greening effect, the grass brick layer enhances the erosion resistance, and the pedestrian facilities improve the user experience.

Description
TECHNICAL FIELD
[0001] The utility model relates to a bank protection structure, concretely relates to a small and medium river bank protection structure. BACKGROUND
[0002] The small and medium river bank protection structure mostly adopts a full bank protection mode. The ecological bank protection is a new type of bank protection structure derived for the purpose of combining ecological beauty without affecting the river drainage and dredging functions. It takes water as the keynote and creates river beauty by combining green ecology. Due to its water-friendly and nature-friendly characteristics, it is deeply loved by people.
[0003] From the purpose, the current bank protection generally focuses on its flood control effect, which leads to poor ecological beauty effect. For the small and medium river bank protection that does not often experience floods, it often leads to no beauty of the small and medium river bank protection, and a bank protection structure suitable for small and medium rivers is needed, which has flood control and ecological beauty. SUMMARY
[0004] The utility model provides a bank protection structure suitable for small and medium rivers, which has good flood control effect and ecological effect.
[0005] The utility model realizes the following technical scheme:
[0006] A small and medium river bank protection structure, comprising,
[0007] A concrete foot;
[0008] A water conservancy structure section, the water conservancy structure section 20 is arranged on the upper portion of the concrete foot, and the water conservancy structure section 20 comprises a base surface ramming layer A, a sand gravel cushion layer A and a concrete panel layer arranged from bottom to surface;
[0009] A water ecological structure section, the water ecological structure section is arranged on the upper portion of the water conservancy structure section, and the water ecological structure section 30 comprises a base surface ramming layer B, a sand gravel cushion layer B, a cultivated soil layer and a grass planting brick layer arranged from bottom to surface; wherein a lock joint stone is arranged between the upper end of the water conservancy structure section and the lower end of the water ecological structure section, a pressing foot stone is arranged on the upper end of the water ecological structure section, and the length of the water conservancy structure section is from the upper portion of the concrete foot to 2 / 3 of the depth of the designed flood level.
[0010] Further, the grass planting bricks of the grass planting brick layer are externally sleeved with square frame beams.
[0011] Further, the grass planting brick layer is paved with colored grass planting bricks.
[0012] Further, the sand gravel of the sand gravel cushion layer A and the sand gravel cushion layer B has a particle size of 5-10 mm.
[0013] Furthermore, a pedestrian railing and a pedestrian walkway are also provided on the top of the bank above the footstone.
[0014] Compared with the prior art, this utility model has the following advantages:
[0015] This utility model has a simple structure. The gravel cushion layer A used in the hydraulic structure section has good permeability, while the concrete panel layer can effectively reduce the river roughness, thereby increasing the cross-sectional flow velocity and mitigating the problems caused by river siltation. In addition, considering the actual conditions of each river, since the normal design flood level is a frequency flood with infrequent occurrences, the hydraulic structure section is used below 2 / 3 of the normal design flood water depth, while the above part uses the water ecological structure section for ecological management, ensuring that the ecological landscape is visible year-round. The grass pavers used in the water ecological structure section have weak erosion resistance, so square frame beams are added to stabilize the grass pavers and reduce the damage caused by erosion. At the same time, since the water ecological structure section is lower and more water-friendly than ordinary revetments, the planted crops are easier to survive, resulting in better greening effects. After achieving good ecological effects, the capping stones, pedestrian railings, and pedestrian walkways on the top of the bank can be customized as needed to achieve a pleasant and scenic environment. Attached Figure Description
