Traditional submerged plant planting methods mainly include shallow water transplanting, boat cutting and throwing seedling planting. Shallow water transplanting is suitable for areas with water depth less than 0.5 meters, and is directly transplanted by artificial; boat cutting is suitable for water depth of 0.5-2.0 meters or even deeper, and the plant roots are inserted into the bottom mud by using a boat and cutting tools; throwing seedling planting is suitable for areas with deep water and hard bottom mud or hard bottom of bottom grouting, and the non-woven fabric bag wrapped with planting soil and plant roots is thrown. However, these traditional planting methods often face problems such as plant root loosening and soil loss caused by water erosion, especially in areas with rapid water flow such as rivers, large lakes and other rapid flow areas, high flow rate water body not only causes plant root loosening and lodging, but also causes substrate loss and destroys the planting substrate. And these rapid flow areas are mostly soft soil, submerged plants are difficult to effectively fix by their own roots, which aggravates the vicious cycle of plant floating and substrate erosion.

[0027] Embodiment 1

[0028] Please refer to Figure 1 The utility model provides a novel is used for planting submerged plant's anti -scouring geogrid, including geogrid room 1 and be used for fixing geogrid room 1's fixing device 2, geogrid room 1 is laid in river channel bottom, geogrid room 1 includes multiple edge zone, multiple edge zone between face to face two two staggered interval and set up and form continuous honeycomb grid structure, honeycomb grid structure constitutes planting cavity, and planting groove inside fills with planting substrate layer.

[0029] Further, the surface of the edge zone is provided with a plurality of planting holes, which form a mesh structure for providing climbing points for plants, and the mesh structure allows water flow to pass through, reduces water flow resistance, and at the same time avoids damaging the river bottom, which is beneficial to the growth and reproduction of submerged plants. The submerged plants are planted in the planting substrate layer, and after a period of growth, the root system can be firmly rooted in the geogrid room 1 and the river bottom soil, thereby enhancing the resistance to lodging.

[0030] It should be noted that the edge zone is made of high-strength, corrosion-resistant synthetic material, has a long service life and low maintenance cost.

[0031] In the fast-flowing area of rivers, large lakes and the like, the soil is often soft, and the high-speed flowing water body has a certain influence on the stability of the geogrid room 1. In order to ensure the stable placement of the geogrid room 1 in these environments, the fixing device 2 is also provided in the utility model, which is installed on the geogrid room 1 to enhance the overall stability and anti-flow impact capability of the geogrid room 1. The fixing device 2 is detachably connected with the geogrid room 1.

[0032] Specifically, as shown in Figure 2 , Figure 3 , the fixing device 2 includes a pile cap, a pile rod, and a pile head, which are connected in sequence from top to bottom into an integrated body; the pile rod is internally provided with an axially extending blind hole type groove, the bottom closed end of the groove is attached to the top surface of the pile head, and the top open end of the groove is attached to the bottom surface of the pile cap; the pile cap is provided with a through hole coaxial with the groove; the side wall of the pile rod is provided with a plurality of holes 3 communicating with the groove.

[0033] The specific installation steps are as follows: the staff member clamps the fixing device 2 at one corner of the earthwork grid, and the clamping groove of the pile cap clamps the adjacent two edge belts. The insertion rod 4 is inserted into the groove through the pile cap, and then the fixing device 2 is pressed into the soil of the river channel as a whole; after all the fixing devices 2 are installed in place, the insertion rod 4 is pulled out. At this time, as shown in Figure 4 , the holes 3 in the side wall of the pile rod suck in part of the soil into the groove through the negative pressure effect, thereby preventing the soil around the fixing device 2 from being lost due to the scouring of high-speed water flow, thereby causing the fixing device 2 to tilt. This design improves the stability of the fixing device 2, thereby enhancing the overall stability of the earthwork grid chamber 1.

[0034] It needs to be explained that the insertion rod 4 is used to install the fixing device 2, and its main function is to help the fixing device 2 to achieve stable anchoring in the soil through insertion and pulling out operations. In this embodiment, the insertion rod 4 is designed as a common rod, and the outer peripheral size thereof matches the inner peripheral size of the groove. This matching design ensures that the insertion rod 4 can be closely embedded in the groove, and at the same time, it will not be difficult to pull out due to excessive friction during pulling out, thereby ensuring the smoothness of installation and operation.

[0035] In this embodiment, the holes 3 in the side wall of the pile rod are radial holes;

[0036] Further, the bottom surface of the pile cap is designed with a U-shaped clamping groove, and when the fixing device 2 fixes the earthwork grid chamber 1, the upper end of the edge belt can be closely embedded in the clamping groove, thereby ensuring that the earthwork grid chamber 1 remains stable under the impact of water flow and prevents it from shifting or tilting.

[0037] Further, the bottom surface of the pile cap is designed with a U-shaped clamping groove, and when the fixing device 2 fixes the earthwork grid chamber 1, the upper end of the edge belt can be closely embedded in the clamping groove, thereby ensuring that the earthwork grid chamber 1 remains stable under the impact of water flow and prevents it from shifting or tilting.

[0038] Further, the upper end of the through hole of the pile cap is specially provided with a guide chamfer, which makes it easier for the staff member to insert the fixing rod into the fixing device 2 during installation, thereby improving the installation efficiency and accuracy.

[0039] Furthermore, the pile head is a tapered structure that tapers from top to bottom, which facilitates the pressing of the fixing device 2 into the soil.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that the hole 3 on the side wall of the pile is an oblique hole, such as... Figure 5 As shown, the direction of the inclined hole is at a certain angle to the horizontal plane, with the angle ranging from 0 to 90 degrees. The design of the inclined hole creates a certain resistance within the hole 3 when the sucked-in soil is drawn in, thereby further enhancing the pull-out resistance of the fixing device 2.

[0042] Example 3

[0043] In this embodiment, based on Embodiment 1 or Embodiment 2, the edge of the honeycomb-shaped geocell 1 is divided into a connecting part 5 and a fixing part. A fixing device 2 is installed on the fixing part to fix the geocell 1 to the riverbed. Figure 6 As shown, the connecting part 5 is equipped with a connector for connecting other geocells for assembly and fixation, thereby forming a continuous erosion barrier that allows water flow to pass through while reducing water flow resistance, and effectively prevents soil loss and loosening of plant roots.

[0044] It should be noted that, in this embodiment, the connector includes a male snap-fit ​​component or a female snap-fit ​​component, such as... Figure 7 As shown, adjacent geocells are securely connected by male and female snap fasteners.
