Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, and in particular to a modular biodegradable soil and water conservation blanket. Background Technology

[0002] Currently, there are numerous problems in the soil and water conservation and related construction technologies for permanent and temporary slope protection in development projects such as river management and road construction in my country. Firstly, traditional construction methods involve high intensity, heavy and single-function construction materials, significant manpower and material resources consumption, and limited versatility, making it difficult to simultaneously meet the needs of protection and vegetation growth. Secondly, when encountering steep slopes or vertical facades, existing technologies struggle to provide stable support, leading to significant difficulties and high costs in soil and water conservation and greening construction. The construction procedures are cumbersome, with numerous quality control points, making it difficult to guarantee quality, and the subsequent fertilization and maintenance workload is also substantial. Furthermore, prolonged site exposure during construction can easily lead to soil erosion, dust storms, and environmental degradation due to strong winds and rainfall. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a modular biodegradable soil and water conservation blanket.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution:

[0005] The modular biodegradable soil and water conservation blanket of this utility model includes a flexible support frame, a plant growth substrate pad disposed inside the flexible support frame, and a biodegradable mesh surface layer covering the outside of the flexible support frame; wherein, the flexible support frame is formed by parallel rectangular upper frame and rectangular lower frame enclosed by multiple vertical connecting ribs, and reinforcing ribs are arranged in a grid pattern inside the rectangular upper frame and rectangular lower frame; the plant growth substrate pad consists of a soil layer of formula fertilizer mixed with rooting powder, a plant seed layer and a soil covering layer from bottom to top, the outside of the plant growth substrate pad is covered with a biodegradable outer layer, and water and fertilizer pipelines are buried inside the plant growth substrate pad.

[0006] Furthermore, anchoring through holes are vertically formed at the intersection of the transverse and longitudinal stiffening plates of the reinforcing ribs, and connecting through holes corresponding to the anchoring through holes are formed on the plant growth substrate pad. The anchoring through holes and connecting through holes facilitate the passage of anchoring nails, thereby firmly fixing the flexible support frame together with the plant growth substrate pad to the slope or vertical surface.

[0007] Furthermore, matching male and female locking buckles are provided on the vertical connecting ribs on opposite sides of the flexible support frame to facilitate the quick splicing of multiple flexible support frames together.

[0008] Furthermore, the inlet and outlet ends of the water and fertilizer pipelines have matching snap ring connectors, and the two snap ring connectors are inserted through the vertical connecting ribs on opposite sides of the flexible support frame, so that when the two sets of flexible support frames are spliced ​​together, the water and fertilizer pipelines buried in the plant growth substrate pad can also be easily connected.

[0009] The advantages of this utility model are that its modular design enables rapid splicing and paving, thus adapting to different terrains and forming a large-scale overall protection of soil and water conservation blankets. This greatly improves adaptability and flexibility, reduces construction difficulty, ensures construction quality, reduces labor intensity, and reduces the consumption of manpower and material resources. In addition, the biodegradable outer layer covering the plant growth substrate and the biodegradable mesh surface layer covering the flexible support frame can effectively protect the plant growth substrate while ensuring plant growth. They can also absorb rainwater and intercept surface runoff to allow it to infiltrate, reduce evaporation, save water resources, avoid soil erosion caused by severe weather such as strong winds and heavy rains, and solve the problem of dusty construction environments.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1-3 As shown, the modular biodegradable soil and water conservation blanket of this utility model includes a flexible support frame 1, a plant growth substrate pad 2 disposed inside the flexible support frame 1, and a biodegradable mesh surface layer 3 covering the outside of the flexible support frame 1.

[0015] Specifically, the flexible support frame 1 is formed by parallel rectangular upper frame 1.1 and rectangular lower frame 1.2 enclosed by multiple vertical connecting ribs 1.3, forming an overall rectangular frame structure. Reinforcing ribs 1.4 are also arranged in a grid pattern within the rectangular upper frame 1.1 and rectangular lower frame 1.2. The reinforcing ribs 1.4 within the rectangular upper frame 1.1 and rectangular lower frame 1.2 are aligned vertically to enhance the support strength of the entire flexible support frame 1.

[0016] The plant growth substrate pad 2 consists of a soil layer 2.1 containing a formula fertilizer mixed with rooting powder, a plant seed layer 2.2, and a soil covering layer 2.3, from bottom to top. In addition, a biodegradable outer layer 4 covers the entire outside of the plant growth substrate pad 2. Water and fertilizer pipelines 5 are also buried inside the plant growth substrate pad 2. The biodegradable outer layer 4 plays a role in fixing, covering and protecting the loose material at the bottom in the early stage of plant growth and development, while the water and fertilizer pipelines 5 can easily realize the irrigation function.

[0017] Furthermore, anchoring through holes 6 can be vertically opened at the intersection of the transverse and longitudinal stiffeners of the reinforcing bar 1.4. The anchoring through holes 6 on the reinforcing bars 1.4 on the inner side of the rectangular upper frame 1.1 and the rectangular lower frame 1.2 are coaxially aligned. At the same time, connecting through holes 7 corresponding to the anchoring through holes 6 are opened on the plant growth substrate pad 2. This allows the anchoring nails to easily pass through the anchoring through holes 6 and the connecting through holes 7, thereby firmly fixing the flexible support frame 1 together with the plant growth substrate pad 2 to the slope or vertical surface of the riverbank where soil and water conservation construction is required.

[0018] Furthermore, matching male and female locking buckles 8 can be provided on the vertical connecting ribs 1.3 on opposite sides of the flexible support frame 1. Specifically, male and female recessed buckles 8.1 are provided on the vertical connecting ribs 1.3 on the front side of the flexible support frame 1, male and female protruding buckles 8.2 are provided on the vertical connecting ribs 1.3 on the rear side of the flexible support frame 1, male and female recessed buckles 8.1 are provided on the vertical connecting ribs 1.3 on the left side of the flexible support frame 1, and male and female protruding buckles 8.2 are provided on the vertical connecting ribs 1.3 on the right side of the flexible support frame 1. The male and female recessed buckles 8.1 and male and female protruding buckles 8.2 are adapted to each other and together form a letter-locking buckle 8 that can be quickly inserted and fixed, thereby facilitating the rapid splicing of multiple flexible support frames 1 together. At the same time, matching spring clips 9 should be installed at the inlet and outlet of the water and fertilizer pipeline 5. The two spring clips 9 at the inlet and outlet of the water and fertilizer pipeline 5 are respectively inserted on the vertical connecting ribs 1.3 on opposite sides of the flexible support frame 1, so that the water and fertilizer pipeline 5 buried in the plant growth substrate pad 2 can be easily connected when the two sets of flexible support frames 1 are spliced.

[0019] In actual installation, the modular biodegradable soil and water conservation blankets described in this utility model can be prefabricated in the factory according to the specific conditions of the construction site, and then transported to the construction site for direct splicing and installation. The modular design enables the rapid splicing of two adjacent soil and water conservation blankets, thereby adapting to different terrains and forming a large-scale overall protection of soil and water conservation blankets, greatly improving adaptability and flexibility, reducing construction difficulty, ensuring construction quality, reducing labor intensity, and reducing the consumption of manpower and material resources. In addition, the biodegradable outer layer 4 covering the plant growth substrate pad 2 and the biodegradable mesh surface layer 3 covering the flexible support frame 1 can effectively protect the plant growth substrate pad 2 while ensuring plant growth, attracting rainwater and intercepting surface runoff to allow it to infiltrate, reducing evaporation, saving water resources, avoiding soil erosion caused by severe weather such as strong winds and heavy rains, solving the problem of dusty construction environment, and ultimately degrading and dissolving after a certain period of time.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
