Technical Field
[0001] The utility model relates to the technical field of ecological blankets, and particularly relates to an ecological blanket convenient for laying. Background Technique
[0002] An ecological blanket is a sheet-shaped profile formed by compounding geotextiles and supporting maintenance materials such as mixed grass-seed cloth under special equipment, and is mainly used for preventing scouring of slopes such as river channels, lake shores, and reservoirs. The ecological blanket has a loose and porous structure and the characteristics of water retention and air permeability, can control hydraulic erosion and soil loss, and achieve the effects of anti-scouring and resistance to flow velocity. In the Yangtze Estuary and tidal flat areas, in order to adapt to the local environment, ecological blankets laid with Scirpus mariqueter grass seeds are generally used.
[0003] An ecological blanket generally includes two composite net-like structures, and maintenance materials, matrix cloth and other structures are generally filled between the two net-like structures so that the Scirpus mariqueter grass seeds can obtain a growth cultivation environment and sufficient nutrients after the ecological blanket is laid, prompting them to germinate and grow, and finally forming a stable vegetation cover layer. This can not only effectively prevent soil erosion and scouring, but also improve the quality of the ecological environment and increase biodiversity.
[0004] However, during the laying process of the above ecological blanket, due to the purpose of using the ecological blanket, it generally needs to be laid below the water surface and directly covered on the soil of the tidal flat. This makes the ecological blanket not only affected by the impact of water waves on the water surface, but also the part below the water surface will be affected by undercurrents, which not only increases the laying difficulty of the ecological blanket, but also easily causes impact and dragging on the laid ecological blanket, resulting in the ecological blanket being unable to play the role of soil fixation and waterproofing; in view of this, we propose an ecological blanket convenient for laying. Content of the Utility Model

[0010] Preferably, the reinforcing belt penetrates through the bottom cushion cloth, and both the upper and lower sides of the reinforcing belt extend beyond the upper and lower surfaces of the bottom cushion cloth. Frame-shaped fitting grooves adapted to the reinforcing belt are provided on the bottom surface of the seed attachment cloth and the top surface of the bottom net to facilitate the mutual splicing and installation of the seed attachment cloth, the bottom cushion cloth, and the bottom net.
[0011] Preferably, the width of the hook tooth is adapted to the width of the swing groove, and rotation holes adapted to the rotating rod are provided on the left and right inner walls of the swing groove, so that the hook tooth can freely rotate at a certain angle with the rotating rod as the rotation axis.

[0026] In an embodiment of the present invention, a reinforcing belt 71 is fixedly installed on the outer wall at the edge of the bottom cushion cloth 5, a swing groove 72 is opened on the inner wall of the reinforcing belt 71, a rotating rod 73 is rotatably installed on the inner wall of the swing groove 72, the rotating rod 73 penetrates and is fixedly installed with a barb 74, an arc groove 75 is opened on the side wall of the barb 74, a groove 76 is opened on the side wall of the barb 74, and a hook connection port 77 is opened on the inner wall of the bottom net 6.
[0027] Furthermore, both the top net 1 and the bottom net 6 are made of geotextiles, and both the top net 1 and the bottom net 6 are arranged in a mesh porous structure, so that while the top net 1 and the bottom net 6 play the role of shaping the entire ecological blanket, they will not affect the infiltration of external moisture into the center of the ecological blanket. At the same time, the maintenance fabric 2 is made of natural fibers such as coconut coir or straw to provide necessary nutrition and moisture support for the growth of Scirpus mariqueter seeds. In addition, a number of fine holes are provided inside the top cushion cloth 3 and the bottom cushion cloth 5 to facilitate the penetration of moisture and the germination and upward growth of Scirpus mariqueter seeds, avoiding completely enclosing the germination of Scirpus mariqueter seeds, and a number of organic fertilizers are evenly laid on the top cushion cloth 3 to provide growth nutrients for Scirpus mariqueter seeds.
[0028] In addition, the number of soil-fixing mechanisms 7 is set to several groups, and several groups of soil-fixing mechanisms 7 are evenly distributed in a rectangular array at the edge of the bottom cushion cloth 5. At the same time, the reinforcing belt 71 penetrates through the bottom cushion cloth 5, and both the upper and lower sides of the reinforcing belt 71 extend beyond the upper and lower surfaces of the bottom cushion cloth 5. Specifically, frame-shaped fitting grooves adapted to the reinforcing belt 71 are provided on the bottom surface of the seed attachment cloth 4 and the top surface of the bottom net 6 to facilitate the mutual splicing and installation of the seed attachment cloth 4, the bottom cushion cloth 5, and the bottom net 6. At the same time, the width of the hook tooth 74 is adapted to the width of the swing groove 72, and rotation holes adapted to the rotating rod 73 are provided on the inner walls of the left and right sides of the swing groove 72, so that the hook tooth 74 can freely rotate at a certain angle with the rotating rod 73 as the rotation axis. Specifically, the hook tooth 74 is set in an arc shape, and both the arc-shaped groove 75 and the groove 76 are provided on this arc surface. At the same time, the arc-shaped groove 75 and the groove 76 are perpendicular to each other, and the extending direction of the groove 76 is the same as that of the hook tooth 74.
[0029] In the embodiment of the present utility model, the number of hook teeth 74 is set to several groups, and several groups of hook teeth 74 are evenly distributed around the bottom cushion cloth 5, and the hook teeth 74 on one side of the bottom cushion cloth 5 are arranged in a linear array.

When laying, a laying device is used to lay the bottom net 6 on the side facing the ground below the water surface or on the mudflat. When the bottom net 6 approaches the ground and finally adheres, the hook teeth 74 will first come into contact with the ground soil, and due to different soil resistances, the hook teeth 74 will deflect at a certain angle with the rotating rod 73 as the rotation axis. Finally, when the laying device makes the ecological blanket completely adhere to the soil, several hook teeth 74 completely extend below the ground to cooperate with the bottom net 6 and the bottom padding cloth 5 to achieve a more stable soil fixation effect on the ecological blanket, preventing it from being separated from the ground due to the impact of water waves or the undercurrent below the water surface, affecting the normal use of the Scirpus mariqueter ecological blanket, and cooperating with the nutrients in the maintenance fabric 2 to promote the germination and growth of Scirpus mariqueter grass seeds, and finally forming a stable Scirpus mariqueter vegetation coverage layer in this area, which can not only effectively prevent soil erosion and erosion, but also improve the ecological environment quality and increase biodiversity.
