Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a fixing device for a concrete anti-slide slope with vegetation. Background Technology

[0002] In the fields of water conservancy engineering and ecological restoration, slope vegetation concrete technology is widely used in slope protection and greening projects. Its main purpose is to achieve slope stability and ecological restoration through hydroseeding, while also achieving aesthetic effects. However, in actual construction, traditional slope vegetation construction methods have many problems, seriously affecting project quality and subsequent greening results.

[0003] Currently, slope vegetation construction mostly adopts direct hydroseeding. This method easily leads to uneven vegetation distribution, especially when the hydroseeding is too thick or the slope is too steep. Heavy rain can wash away the vegetation seeds, causing soil loss at the base of the concrete anti-slip slope and greatly increasing the risk of landslides. Such landslides not only damage the overall stability of the slope but also cause large-scale vegetation loss, severely impacting the survival rate and aesthetics of slope greening.

[0004] To address these issues, some projects have employed wire mesh covering, where wire mesh is fixed to the slope surface before spraying. However, wire mesh is susceptible to environmental factors, leading to corrosion, rust, and even breakage, thus losing its anchoring function.

[0005] Therefore, there is an urgent need for a new type of concrete slope vegetation fixing device to solve the problem of vegetation spraying on concrete anti-slide slopes. Utility Model Content

[0006] To solve the above problems, this utility model provides a fixing device for a vegetation concrete anti-slip slope.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A fixing device for a vegetation concrete anti-slide slope, the fixing device for the vegetation concrete anti-slide slope includes straw ropes and U-shaped round steel ground nails.

[0009] Several straw ropes are laid horizontally on the slope surface, and each straw rope is fixed to the slope by several U-shaped round steel nails; the U-shaped round steel nails are U-shaped structures with an opening at the bottom, with nails on both sides of the opening, and the bottom of the nails is a spike that can be inserted into the soil; the U-shaped round steel nails can limit the straw ropes inside the opening.

[0010] Furthermore, the straw ropes are laid horizontally on the slope surface at 150cm intervals, forming a stepped pattern after being laid horizontally.

[0011] Furthermore, the fixing device for the vegetation concrete anti-slip slope also includes stainless steel wire, which is wrapped around the straw rope and then tied to the U-shaped round steel ground nail.

[0012] Furthermore, the U-shaped round steel ground nail is 25cm long, 4cm wide, and 6mm in diameter; the straw rope is 10m long and 3.8cm in diameter; and the stainless steel wire is 25cm long and 0.1cm in diameter.

[0013] The beneficial effects of this utility model are:

[0014] 1. Preventing landslides and enhancing stability: By combining U-shaped round steel nails and straw ropes, the device can be firmly fixed to the slope surface, forming a stepped structure that effectively prevents vegetation and concrete from sliding down due to rain erosion or uneven distribution. This design significantly improves the overall stability and anti-slide capacity of the slope.

[0015] 2. Improve the uniformity of vegetation concrete distribution: Straw ropes, used as a support, are laid horizontally at regular intervals and fixed to the slope, guiding the vegetation concrete to distribute evenly and avoiding the problems of excessively thick or thin areas in traditional construction. Evenly distributed vegetation concrete not only enhances adhesion but also improves the survival rate of grass seeds.

[0016] 3. Robust structure and strong corrosion resistance: The U-shaped round steel ground nails are made of galvanized material, and the stainless steel wire has excellent corrosion resistance. It can resist environmental erosion for a long time and ensure the long-term effectiveness of the device under harsh conditions, avoiding the problems of easy corrosion and breakage of traditional iron wire mesh.

[0017] 4. Convenient construction and easy maintenance: The device has a simple structure and is easy to install. On-site operation requires no complicated tools or special skills, which significantly improves construction efficiency. At the same time, it facilitates later maintenance and reduces project costs.

[0018] 5. Enhanced aesthetics and ecological benefits: The stepped layout makes the slope surface smoother and more even, improving the visual effect of the greening; the evenly distributed vegetation concrete provides a good foundation for subsequent vegetation growth, significantly improving the ecological greening effect of the slope.

[0019] In summary, this fixed device for vegetation concrete anti-slide slopes solves the technical defects of traditional methods and has the advantages of strong stability, convenient construction, aesthetics and durability. It is suitable for water conservancy projects and ecological restoration, and has important promotion value and engineering application prospects. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] To address the issue of vegetation spraying on concrete slopes used for landslide prevention, this embodiment provides a fixing device for vegetation-covered concrete slopes used for landslide prevention. For example... Figure 1 and Figure 2 As shown, the fixing device for the vegetation concrete anti-slip slope includes grass ropes 1 and U-shaped round steel nails 2; several grass ropes 1 are laid horizontally on the surface of the slope 5, and each grass rope 1 is fixed to the slope 5 by several U-shaped round steel nails 2; the U-shaped round steel nail 2 is a U-shaped structure with an opening at the bottom, and the two sides of the opening are nails 3, and the bottom of the nail 3 is a spike end 4 that can be inserted into the soil; the U-shaped round steel nail 2 can limit the grass ropes 1 in the opening.

[0025] In this embodiment, straw ropes 1 are laid horizontally on the surface of slope 5 at 150cm intervals. Each straw rope 1 is fixed to the slope 5 by several U-shaped round steel nails 2, forming a stepped shape. Each straw rope 1 is 10m long and 3.8cm in diameter. To avoid corrosion, rust, and breakage caused by environmental factors, the U-shaped round steel nails 2 in this embodiment are 25cm long and 4cm wide, and are made of galvanized round steel with a diameter of 6mm.

[0026] Furthermore, to further ensure the stability of the straw rope 1, as a preferred technical solution in this embodiment, a stainless steel wire with a length of 25cm and a diameter of 0.1cm can be used. This wire can be wrapped around the straw rope 1 and then tied to the U-shaped round steel nail 2 to ensure the stability of the straw rope 1. The stainless steel wire is not shown in the figure.

[0027] The fixing device for this vegetation-concrete anti-slip slope utilizes the synergistic action of U-shaped round steel nails (2), stainless steel wire, and straw rope (1) to form a stepped fixing structure. The working principle of this device is as follows:

[0028] Straw rope 1 is laid horizontally on the surface of slope 5 as a support carrier, serving as the main support carrier for the vegetation concrete. The straw rope 1 has the characteristics of flexibility and rough surface, which can effectively increase the friction and adhesion between the straw rope and the vegetation concrete, while providing a uniformly distributed foundation for the vegetation concrete.

[0029] The U-shaped round steel ground stake 2 securely fixes the straw rope 1 to the slope 5, preventing the straw rope 1 from slipping due to gravity or rain erosion. The U-shaped design of the U-shaped round steel ground stake 2 allows it to penetrate deep into the soil and be fixed to the surface of the slope 5, thus providing sufficient rigidity and stability for the entire device.

[0030] After the straw rope 1 is secured with U-shaped round steel nails 2, stainless steel wire is used to bind and reinforce the device, further improving the overall structural stability and tensile strength. Stainless steel wire has excellent corrosion resistance, ensuring the device remains robust for a long time and preventing breakage or failure due to environmental factors.

[0031] The device uses spaced-apart straw ropes 1 and U-shaped round steel nails 2 to form a stepped structure, allowing the sprayed vegetation seeds to be evenly distributed on the slope 5. This arrangement not only enhances the adhesion of the vegetation seeds but also effectively disperses the impact force of water flow, reducing the risk of landslides.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
