Description

Technical Field

[0001] This utility model relates to the field of padding technology, specifically to a padding material for bank slope protection. Background Technology

[0002] Bank slope protection mats are protective structures laid on or inside bank slopes. After being filled with hard materials such as stones, they form a stable protective structure. In rivers or embankment projects with high flow rates, water erosion is one of the main challenges faced by bank slope protection. Mats can effectively prevent soil loss and prevent river water from eroding the riverbank, protecting the bank slope from water erosion.

[0003] Existing slope protection mats are fixed to the slope surface by simply filling them with hard materials such as stones. However, they have poor overall integrity and lack sufficient compressive strength. After long-term use, when subjected to external forces (such as water erosion, wind erosion, soil pressure, etc.), the mats are prone to displacement and deformation. This displacement and deformation will further affect the stability of the slope, increase the risk of landslides and collapses, and thus affect their protective effect and service life.

[0004] For example, the hydraulic slope protection disclosed in patent CN218911282U lacks effective restraint on the upper and lower slope protection blocks. When subjected to natural factors such as water erosion and wind erosion, the slope protection blocks are prone to displacement and deformation, leading to a decrease in the stability of the bank slope and increasing the risk of landslides and collapses. Furthermore, the upper and lower slope protection blocks lack sufficient support structures, have poor resistance to deformation, cannot effectively resist erosion and damage from the external environment, are difficult to withstand external loads and deformations, and are prone to damage.

[0005] Therefore, it is necessary to invent a type of pad for bank slope protection to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a slope protection pad to solve the problems of insufficient support structure, poor deformation resistance, inability to effectively resist external environmental erosion and damage, difficulty in bearing external loads and deformation, and easy damage in the current technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a slope protection mat, comprising an outer mesh mat, a mat body, a high-strength geotextile bag, and anchor nails. The mat body is located in the middle of the outer mesh mat, and a high-strength geotextile bag is located above the mat body. The high-strength geotextile bag includes an outer bag and an inner bag inside the outer bag. An anchor nail is located above the outer mesh mat and extends through to the bottom of the high-strength geotextile bag. The mat body is provided with a side steel reinforcement skeleton, an upper steel reinforcement skeleton, and a lower steel reinforcement skeleton inside. The upper steel reinforcement skeleton is located on the top surface inside the mat body, and the lower steel reinforcement skeleton is located on the bottom surface inside the mat body.

[0008] Preferably, the outer bag and the inner bag are fixed by sewing. The inner bag is filled with sand and gravel. The sand and gravel filling not only increases the weight of the high-strength geotextile bag, but also improves its erosion resistance, which helps to maintain the stability of the pad on the bank slope.

[0009] Preferably, the outer mesh pad is fixed to the four edges of the high-strength geotextile bag by sewing, which tightly connects the outer bag and the inner bag to ensure the integrity and stability of the high-strength geotextile bag.

[0010] Preferably, a first geotextile strip is provided around the outer perimeter of the high-strength geotextile bag, and a second geotextile strip is provided around the outer perimeter of the outer mesh mat. The first geotextile strip and the second geotextile strip are tied together and fixed, and the tying of the first geotextile strip and the second geotextile strip further strengthens the connection between the high-strength geotextile bag and the outer mesh mat.

[0011] Preferably, four anchoring nails are provided. An anchoring hole No. 1 is opened at the contact position between the four anchoring nails and the high-strength geotextile bag, and anchoring hole No. 2 is opened at the contact position between the four anchoring nails and the outer mesh mat. The anchoring nails firmly fix the high-strength geotextile bag and the mat body to the bank slope, preventing them from moving or overturning under the action of water flow or wind.

[0012] Preferably, the bottom of the pad body is provided with a gravel transition layer, which enhances the bonding force between the pad body and the slope surface and prevents the pad body from separating from the slope surface under the action of gravity or external force.

[0013] Preferably, the side reinforcing bar skeleton is made of hot-rolled low-carbon steel bar. The side reinforcing bar skeleton is closely attached to the inner edge of the pad body. An upper reinforcing bar skeleton is provided above the side reinforcing bar skeleton, and a lower reinforcing bar skeleton is provided below the side reinforcing bar skeleton. The side reinforcing bar skeleton, the upper reinforcing bar skeleton, and the lower reinforcing bar skeleton provide a strong internal support structure for the pad body, enhancing its resistance to deformation and damage.

[0014] Preferably, both the upper and lower reinforcing bar skeletons are made of hot-rolled low-carbon steel round bars. The upper reinforcing bar skeleton is closely attached to the top surface inside the pad body, and the lower reinforcing bar skeleton is closely attached to the bottom surface inside the pad body. The side reinforcing bar skeletons, the upper reinforcing bar skeleton, and the lower reinforcing bar skeleton are fixed by welding. The welding method ensures that the connection between them is firm and reliable, further improving the overall structural strength of the pad.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By setting up high-strength geotextile bags, the high-strength geotextile bags are fixedly laid on top of the mattress body, which can further improve the restraint force on the mattress body. The combined use of high-strength geotextile bags and mattress body forms a stable protective layer, which can not only resist water erosion, but also limit the displacement and deformation of the mattress body, further strengthen the slope structure, form a more stable ecological protection system, and effectively prevent slope landslides and collapses.

[0017] 2. By setting up the side steel reinforcement cage, the upper steel reinforcement cage, and the lower steel reinforcement cage, a stable frame is formed. The stable frame is set inside the mattress body as a support structure, which can significantly improve the overall strength and rigidity of the mattress body. The combination of this steel reinforcement cage and the concrete or stone blocks injected inside it complement each other, effectively resisting external loads and deformations, maintaining good stability, reducing the risk of displacement and overturning, extending the service life of the mattress body, and improving the slope protection and reinforcement effect.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The illustrated pad for bank slope protection includes an outer mesh pad 1, a pad body 2, a high-strength geotextile bag 3, and anchor nails 6. The pad body 2 is located in the middle of the outer mesh pad 1, and the high-strength geotextile bag 3 is located above the pad body 2. The high-strength geotextile bag 3 includes an outer bag 301 and an inner bag 302 inside the outer bag 301. Anchor nails 6 are located above the outer mesh pad 1 and extend through to the bottom of the high-strength geotextile bag 3. The pad body 2 has a side steel reinforcement skeleton 10, an upper steel reinforcement skeleton 11, and a lower steel reinforcement skeleton 12 inside. The upper steel reinforcement skeleton 11 is located on the top surface inside the pad body 2, and the lower steel reinforcement skeleton 12 is located on the bottom surface inside the pad body 2.

[0028] The outer bag 301 and the inner bag 302 are fixed by sewing. The inner bag 302 is filled with sand and gravel 303. The outer mesh 1 and the high-strength geotextile bag 3 are fixed by sewing around their edges. A first geotextile strip 4 is provided around the outside of the high-strength geotextile bag 3. A second geotextile strip 5 is provided around the outside of the outer mesh 1. The first geotextile strip 4 and the second geotextile strip 5 are tied together. There are 4 anchor nails 6. An anchor hole 7 is opened at the contact position between the four anchor nails 6 and the high-strength geotextile bag 3. An anchor hole 8 is opened at the contact position between the four anchor nails 6 and the outer mesh 1.

[0029] The high-strength geotextile bags 3 are fixedly laid on top of the pad body 2. The restraining effect of the high-strength geotextile bags 3 can limit the displacement and deformation of the slope soil, while the pad body 2 provides a solid support foundation. Together, they can effectively resist the damage caused by natural factors such as water erosion and wind erosion. The high-strength geotextile bags 3 and the pad body 2 are tied together with No. 1 geotextile strip 4 and No. 2 geotextile strip 5 to ensure the stability of their connection. At the same time, the high-strength geotextile bags 3 and the pad body 2 are firmly fixed to the slope with anchor nails 6 to provide strong fixing force, thereby further improving the reinforcement effect.

[0030] The bottom of the pad body 2 is provided with a gravel transition layer 9. The side steel reinforcement skeleton 10 is made of low carbon steel hot-rolled round bars. The side steel reinforcement skeleton 10 is closely attached to the inner edge of the pad body 2. An upper steel reinforcement skeleton 11 is provided above the side steel reinforcement skeleton 10, and a lower steel reinforcement skeleton 12 is provided below the side steel reinforcement skeleton 10. Both the upper steel reinforcement skeleton 11 and the lower steel reinforcement skeleton 12 are made of low carbon steel hot-rolled round bars. The upper steel reinforcement skeleton 11 is closely attached to the top surface inside the pad body 2, and the lower steel reinforcement skeleton 12 is closely attached to the bottom surface inside the pad body 2. The side steel reinforcement skeleton 10, the upper steel reinforcement skeleton 11 and the lower steel reinforcement skeleton 12 are fixed by welding.

[0031] The gravel transition layer 9 effectively improves the bonding force between the pad body 2 and the slope, preventing the pad body 2 from separating from the slope under gravity or external force. The side steel reinforcement frame 10 provides lateral support for the pad body 2, while the upper steel reinforcement frame 11 and lower steel reinforcement frame 12 provide vertical support. These steel reinforcement frames are firmly fixed together by welding, forming a stable support network. Thus, the sand or concrete inside the pad body 2 works together with the steel reinforcement frame to significantly enhance the overall stability of the pad body 2, enabling it to resist damage from natural factors such as water erosion and wind erosion.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-4 When using this utility model, first align the gravel transition layer 9 with the position where the pad body 2 needs to be laid on the slope, and place the pad body 2 on the gravel transition layer 9. The gravel transition layer 9 ensures that the pad body 2 is in close contact with the slope surface to improve the bonding force between the pad body 2 and the slope surface. After the pad body 2 is laid, the high-strength geotextile bag 3 can be laid and fixed on top of the pad body 2. First, sew the four edges of the high-strength geotextile bag 3 to the outer mesh 1.

[0034] Next, use the binding method to fix the No. 1 geotextile strip 4 and the No. 2 geotextile strip 5 to each other, further enhancing the connection stability between the high-strength geotextile bag 3 and the outer net mat 1. Finally, drill holes at the predetermined positions and pass the anchor nails 6 through the outer net mat 1 and the high-strength geotextile bag 3, ensuring that the anchor nails 6 pass through the No. 1 anchor hole 7 and the No. 2 anchor hole 8 and penetrate deep into the slope soil. The three methods are used in combination to ensure that the two are tightly connected. In this way, the pad body 2 can be used for slope protection.

[0035] Refer to the instruction manual appendix Figure 5-6When using this utility model, when the pad body 2 is in use, the load-bearing capacity of the pad body 2 can be effectively improved by the combination of the side steel reinforcement skeleton 10, the upper steel reinforcement skeleton 11 and the lower steel reinforcement skeleton 12 inside the pad body 2 with the sand or concrete inside, so that the pad body 2 can further resist the erosion and damage of various natural factors.
