Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a bank protection structure suitable for river ecological restoration. Background Art

[0002] Ecological revetments are designed to meet the basic functions of structural safety and river flood safety. In the range from high water level to low water level, they have water and soil exchange channels or bio-friendly slopes or retaining walls, which can prevent water intrusion and scouring, river bank material exchange, and provide good habitat conditions for aquatic plants and animals. Compared with traditional hard revetments, ecological revetments have obvious advantages in combining engineering safety and ecological friendliness.

[0003] In combination with new landscape and ecological demands, traditional hydraulic revetment structures have gradually developed into a variety of new revetment structures, such as various types of ecological block structure revetments.

[0004] However, the existing block structure revetments generally have a low porosity, lack ecological space after the introduction of animals and plants, and are difficult to build a self-circulating system. At the same time, the strength of the flexible material itself is low, and it is difficult to meet flood safety requirements in the absence of protective measures. Utility Model Content

[0005] The purpose of the utility model is to provide a bank protection structure suitable for river ecological restoration, which is used to solve the problems that the existing block structure bank protection generally has low porosity, lacks ecological space after the release of animals and plants, and is difficult to construct a self-circulation system. At the same time, the strength of the flexible material itself is low, and it is difficult to meet the flood safety requirements.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a bank protection structure suitable for river ecological restoration, including a retaining wall body and a planting mesh plate;

[0007] The retaining wall body is a U-shaped structure, including a bottom plate and two sets of vertical walls, wherein the height of the vertical wall on the water side is lower than the height of the vertical wall on the far water side, and a connecting hole is opened on the vertical wall on the water side, and the connecting hole is used for water to enter the retaining wall body;

[0008] The planting mesh panels are fixedly installed in the retaining wall body, and steps for fixing the planting mesh panels are provided on the close sides of the two groups of vertical walls.

[0009] As a further solution of the utility model, filter stone filler is placed at the bottom of the retaining wall body.

[0010] As a further solution of the utility model, the planting mesh plate is a lightweight porous structure.

[0011] Compared with the prior art, the prefabricated structure of the utility model is simple to construct, the retaining wall body is integrally formed, and the flexible structure is combined with the hard structure. While meeting the flood prevention effect, the opening on the water side of the retaining wall body makes it have a permeable structure with good ecology and good interaction with the animals and plants placed therein, which can easily form a virtuous ecological cycle and improve the survival rate of animals and plants. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The utility model is a schematic structural diagram of a bank protection structure suitable for river ecological restoration.

[0013] In the attached drawings: 1. retaining wall body; 101. vertical wall; 102. bottom plate; 103. connecting hole; 2. filter stone filler; 3. planting mesh plate. DETAILED DESCRIPTION

[0014] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1 As shown, in an embodiment of the utility model, a bank protection structure suitable for river ecological restoration includes a retaining wall body 1 and a planting mesh plate 3, wherein the retaining wall body 1 is a U-shaped structure, including a bottom plate 102 and two groups of vertical walls 101, wherein the height of the bottom of the water-side vertical wall 101 is higher than the height of the water-side vertical wall 101, and a connecting hole 103 is opened on the water-side vertical wall 101, and the connecting hole 103 is used for water to enter the retaining wall body 1, and the planting mesh plate 3 is fixedly installed in the retaining wall body 1, and the near side of the two groups of the vertical walls 101 is provided with a step for fixing the planting mesh plate 3;

[0016] Specifically, the utility model designs the retaining wall body 1 as a hollow structure to reserve space for the activities of animals and plants. A planting mesh plate 3 for planting aquatic plants is arranged in the box body. A hole is opened on the water side of the lower part of the box body to reserve a channel for the activities of benthic animals.

[0017] like Figure 1 As shown, in the embodiment of the utility model, a filter stone filler 2 is placed at the bottom of the retaining wall body 1 to accelerate the deposition of humus and promote plant growth. In conjunction with the box opening on one side of the retaining wall body 1, a microflow environment is formed inside the cavity structure of the retaining wall body 1 to help benthic animals build nests and breed.

[0018] like Figure 1 As shown, in the embodiment of the utility model, the planting mesh plate 3 is a lightweight porous structure, which is convenient for the extension of plant roots.

[0019] To sum up the above, the prefabricated structure of the utility model is simple to construct, the retaining wall body 1 is integrally formed, and the flexible structure is combined with the hard structure. While meeting the flood prevention effect, the opening on the water side of the retaining wall body 1 makes it have a permeable structure, good ecology, good interaction with the animals and plants released, and it is easy to form a virtuous ecological cycle, thereby improving the survival rate of animals and plants.

[0020] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
