Description

Technical Field

[0001] This utility model belongs to the field of foundation pit slope technology, and in particular relates to temporary foundation pit slope vegetation soil stabilization blanket. Background Technology

[0002] Vegetated soil stabilization blankets are a type of composite functional material used for temporary slope protection of foundation pits. They typically consist of a surface protective layer, a vegetation matrix layer, a fiber soil stabilization layer (such as coconut fiber or polypropylene fiber mesh), a bottom bonding layer, and fixing components. They fix the surface soil of the slope through physical structure, while the roots of the grass seeds anchor the soil after germination, achieving temporary soil stabilization to prevent collapse, water and soil conservation, and ecological greening, thus meeting the safety and environmental protection requirements of temporary support.

[0003] Currently, temporary slope stabilization blankets for foundation pits are fixed by driving in individual U-shaped nails one by one. This method suffers from low construction efficiency, easy nail deviation leading to edge warping of the stabilization blanket, and individual nails being subject to independent force, which can easily cause local loosening. Therefore, it is necessary to design a temporary slope stabilization blanket for foundation pits that allows U-shaped nails at the joints to be driven into the soil in a row. This can improve construction efficiency, as the entire row of nails can be driven in a row simultaneously without individual positioning, thus enhancing the stability of the fixation. The steel structure allows the U-shaped nails to form a whole under the force, significantly improving the pull-out resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary slope stabilization blanket for foundation pits, which has the advantages of allowing U-shaped nails at the joints to be driven into the soil in a row, with the entire row being nailed simultaneously without the need for individual positioning, thus enhancing the stability of the fixation. The steel structure makes the U-shaped nails form an integral force-bearing structure, significantly improving the pull-out resistance, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a temporary slope stabilization blanket for foundation pits, comprising multiple stabilization blankets laid on the slope surface of the foundation pit, with U-shaped nails penetrating through both ends of the top of each stabilization blanket, the U-shaped nails penetrating to the bottom of the stabilization blanket and drilling into the inner cavity of the foundation pit slope, and a U-shaped nail frame penetrating on one side of two stabilization blankets facing each other, the reinforcing plate penetrating to the bottom of the stabilization blanket and drilling into the inner cavity of the foundation pit slope, the surface of the U-shaped nail frame being fixedly connected. There are multiple reinforcing plates located on top of two vegetated soil stabilizing blankets. The U-shaped nail frame is fixedly connected to a reinforcing rod. Multiple connecting ribs are fixedly connected to the surface of the reinforcing rod. Two symmetrical diagonal bracing ribs are fixedly connected to the side of the connecting ribs facing the U-shaped nail frame. The two diagonal bracing ribs are fixedly connected to the surface of the reinforcing rod. Two symmetrical supporting ribs are fixedly connected to the front side of the connecting rib away from the diagonal bracing ribs. The ends of the two supporting ribs away from the connecting ribs are fixedly connected to the U-shaped nail frame.

[0006] Preferably, the surface of the U-shaped nail is fixedly connected to two symmetrical circular pieces, and the bottom of both circular pieces are attached to the top of the vegetation soil stabilization blanket.

[0007] Preferably, nails are fixedly connected to the bottom of each of the multiple reinforcing sheets, and the nails penetrate to the bottom of the vegetated soil stabilizing blanket and drill into the inner cavity of the foundation pit slope.

[0008] Preferably, the U-shaped nail frame has two symmetrical stiffening ribs fixedly connected to its front and rear sides, and a fixing rib is fixedly connected to the inner side of the stiffening rib. The end of the fixing rib away from the stiffening rib is welded to the top of the reinforcing plate.

[0009] Preferably, two symmetrical support ribs are fixedly connected to the rear side of the connecting rib away from the diagonal brace. The ends of the two support ribs away from the connecting rib are fixedly connected to the U-shaped nail frame. The support ribs are symmetrical to each other.

[0010] The beneficial effects of this utility model are: 1. This utility model involves laying individual vegetation soil stabilization blankets on the slope of the foundation pit, fixing the corners of the vegetation soil stabilization blankets with U-shaped nails and round plates, and using the combined use of U-shaped nail frames, reinforcing plates, and reinforcing rods to fix the gaps between the vegetation soil stabilization blankets. Finally, the vegetation soil stabilization blankets are stably fixed on the slope of the foundation pit. This achieves the goal of driving U-shaped nails into the soil in rows at the joints, with the entire row being nailed simultaneously without the need for individual positioning, thus enhancing the stability of the fixation. The steel structure makes the U-shaped nails form an integral force-bearing structure, significantly improving the pull-out resistance. 2. By setting up the circular piece, when the U-shaped nail penetrates to the bottom of the vegetation soil stabilization blanket to the inner cavity of the foundation pit slope, the circular piece increases the contact area when fixing the U-shaped nail to the top of the vegetation soil stabilization blanket. This makes the U-shaped nail more stable when fixing the corner of the vegetation soil stabilization blanket, and avoids detachment from the vegetation soil stabilization blanket. 3. By using stiffening ribs and fixing ribs in combination, this utility model strengthens the front and rear sides of the U-shaped nail frame, making the connection force more stable and improving the connection between the U-shaped nail frame and the reinforcing plate and the vegetation soil stabilization blanket.

Detailed Implementation

[0013] In the following description, embodiments of the temporary slope vegetation soil stabilization blanket for foundation pits of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-5This invention illustrates a temporary slope stabilization blanket for a foundation pit, comprising multiple stabilization blankets 2 laid on the slope surface of a foundation pit slope 1. U-shaped nails 3 are inserted through both ends of the top of each stabilization blanket 2, penetrating to the bottom of the blanket and into the inner cavity of the slope 1. Two symmetrical circular pieces 4 are fixedly connected to the surface of each U-shaped nail 3, with the bottoms of the two circular pieces 4 adhering to the top of the blanket 2. Through the arrangement of the circular pieces 4, when the U-shaped nail 3 penetrates to the bottom of the blanket and into the inner cavity of the slope 1, the circular pieces 4 fix the U-shaped nail 3 to the blanket 2. The increased contact area at the top makes the U-shaped nail 3 more stable when fixing the corner of the vegetation soil stabilization blanket 2, preventing it from detaching from the vegetation soil stabilization blanket 2. A U-shaped nail frame 5 is installed through the two vegetation soil stabilization blankets 2 facing each other. Reinforcing plates 6 penetrate to the bottom of the vegetation soil stabilization blanket 2 and drill into the inner cavity of the foundation pit slope 1. Multiple reinforcing plates 6 are fixedly connected to the surface of the U-shaped nail frame 5. These reinforcing plates 6 are located at the top of the two vegetation soil stabilization blankets 2, and nails 7 are fixedly connected to the bottom of each reinforcing plate 6. The nails 7 penetrate to the bottom of the vegetation soil stabilization blanket 2 and drill into the inner cavity of the foundation pit slope 1. The U-shaped nail frame 5... The support is fixedly connected by a reinforcing rod 8. Multiple connecting ribs 9 are fixedly connected to the surface of the reinforcing rod 8. Two symmetrical diagonal bracing ribs 10 are fixedly connected to the side of the connecting rib 9 facing the U-shaped nail frame 5. The two diagonal bracing ribs 10 are fixedly connected to the surface of the reinforcing rod 8. Two symmetrical supporting ribs 13 are fixedly connected to the front side of the connecting rib 9 away from the diagonal bracing ribs 10. The ends of the two supporting ribs 13 away from the connecting rib 9 are fixedly connected to the U-shaped nail frame 5. Two symmetrical stiffening ribs 11 are fixedly connected to the front, back, and rear sides of the U-shaped nail frame 5. A fixing rib 14 is fixedly connected to the inner side of the stiffening rib 11. 4. The end away from the stiffening rib 11 is welded to the top of the reinforcing plate 6. The rear side of the connecting rib 9 away from the diagonal bracing rib 10 is fixedly connected to two symmetrical support ribs 12. The ends of the two support ribs 12 away from the connecting rib 9 are fixedly connected to the U-shaped nail frame 5. The support ribs 12 and the support ribs 13 are symmetrical. Through the combined use of the stiffening rib 11 and the fixing rib 14, the fixing rib 14 and the stiffening rib 11 reinforce the front and rear sides of the U-shaped nail frame 5, making the connection force more stable and improving the connection between the U-shaped nail frame 5 and the reinforcing plate 6 and the vegetation soil stabilization blanket 2.

[0015] Working Principle: When using this utility model, firstly, according to the slope dimensions of the foundation pit slope 1, multiple vegetation soil stabilization blankets 2 are laid flat on the slope surface one by one, ensuring that the edges of adjacent vegetation soil stabilization blankets 2 are tightly joined, laying the foundation for subsequent fixing and seepage prevention. For a single vegetation soil stabilization blanket 2, at both ends of its top, U-shaped nails 3 with round plates 4 are vertically inserted through the vegetation soil stabilization blanket 2, and the U-shaped nails 3 are drilled into the soil of the foundation pit slope 1 with the help of special nailing equipment. The round plates 4 are used to increase the contact area with the vegetation soil stabilization blanket 2, preventing the U-shaped nails 3 from loosening and falling off, and achieving stable positioning of the corner of a single vegetation soil stabilization blanket 2. For the joint of adjacent vegetation soil stabilization blankets 2, a U-shaped nail frame 5 is used for overall fixing. First, the U-shaped nail frame 5 is laid across the joint, covering the top of the vegetation soil stabilization blankets 2 on both sides, and then multiple reinforcing plates fixed on its surface are used for further fixing. 6. Insert the reinforcing plate 6 with nails 7 at the bottom through the vegetation soil stabilization blanket 2 and drill it into the slope soil. At the same time, use the stiffening ribs 11 and fixing ribs 14 on the front and rear sides of the U-shaped nail frame 5 to strengthen the connection stability between the U-shaped nail frame 5 and the reinforcing plate 6, forming a row of fixed structures at the joint. There is no need to position the U-shaped nails one by one. The reinforcing rods 8 fixed on the U-shaped nail frame 5 form a three-dimensional support system through the connecting ribs 9, the diagonal bracing ribs 10, and the first support rib 12 and the second support rib 13. The diagonal bracing ribs 10, the first support rib 12, and the second support rib 13 reinforce the connecting ribs 9 and the U-shaped nail frame 5 from different angles, so that the U-shaped nail frame 5, the reinforcing plate 6 and each support component form an integral load-bearing structure, which significantly improves the pull-out resistance and overall stability, effectively prevents the vegetation soil stabilization blanket 2 from curling up, and achieves comprehensive and stable fixation of the vegetation soil stabilization blanket 2 on the slope surface of the foundation pit 1.

[0016] In summary, this temporary slope stabilization blanket for the foundation pit works by laying individual stabilization blankets 2 on the slope surface of the foundation pit 1, fixing the corners of the stabilization blankets 2 with U-shaped nails 3 and round pieces 4, and using the combined use of U-shaped nail frames 5, reinforcing pieces 6, and reinforcing rods 8 to fix the gaps between the stabilization blankets 2. Finally, the stabilization blankets 2 are stably fixed on the slope surface of the foundation pit 1. This achieves the goal of driving U-shaped nails into the soil in rows at the joints, with the entire row being nailed simultaneously without the need for individual positioning, thus enhancing the stability of the fixation. The steel structure allows the U-shaped nails to form an integral force-bearing structure, significantly improving the pull-out resistance.
