Description

Technical Field

[0001] This invention relates to the field of oil and gas long-distance pipeline technology, and in particular to an eco-bag reinforced retaining wall. Background Technology

[0002] In long-distance oil and gas pipeline projects, retaining walls are often used to prevent natural disasters such as landslides and collapses from damaging the pipelines, while also serving the function of soil and water conservation.

[0003] Currently, gravity retaining walls, mostly masonry retaining walls, are commonly used in the hydraulic engineering design of long-distance pipelines. They resist lateral soil pressure through their own weight, preventing pipeline damage due to slope instability. Simultaneously, they reduce soil erosion, decreasing the amount of sediment entering the pipeline and lowering the risk of corrosion. While reinforced retaining walls have been researched, they have been largely unused. This is mainly because reinforced retaining walls require high construction standards; poor construction quality will render them ineffective, directly leading to the failure of the hydraulic structure. Furthermore, although the aforementioned retaining wall structures effectively prevent damage to pipelines from natural disasters such as landslides and collapses, they still have shortcomings in terms of environmental aesthetics.

[0004] Therefore, there is an urgent need for an eco-bag reinforced retaining wall to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an eco-bag reinforced retaining wall that can achieve structural protection, has high structural strength and good stability, and can also beautify the ecological environment and achieve good greening effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The eco-bag reinforced retaining wall includes a multi-layer retaining wall structure, wherein the multiple layers of the aforementioned retaining wall structure are stacked vertically on one side of the soil to form a sloped wall panel; the aforementioned soil includes multiple layers of fill soil stacked vertically.

[0008] The aforementioned retaining wall structure includes tie rods and multiple eco-bags. The eco-bags are used for greening the soil. The multiple eco-bags are stacked along a first horizontal direction, and at least one layer of the multiple eco-bags is laid along the aforementioned vertical direction. The first horizontal direction and the aforementioned vertical direction are perpendicular to each other. The tie rods cover the outer periphery of the multiple eco-bags, and the side of the tie rods away from the eco-bags forms a fixing layer to be laid and fixed between two adjacent backfill layers.

[0009] Optionally, the aforementioned tie rod is folded to form two reinforcing layers. The first reinforcing layer is laid between two adjacent fill layers, and the second reinforcing layer is wrapped around the ecological bag and fixedly connected to the first reinforcing layer.

[0010] Optionally, the retaining wall structure includes a plurality of binding members, which are distributed along the first horizontal direction and are used to bind and fix the first layer of the reinforcement layer and the second layer of the reinforcement layer.

[0011] Optionally, multiple binding members distributed along the first horizontal direction are configured as binding groups, and multiple binding groups are spaced apart along the second horizontal direction, with the first horizontal direction, the second horizontal direction, and the vertical direction being perpendicular to each other.

[0012] Optionally, the aforementioned tie rod is a geogrid.

[0013] Optionally, the aforementioned ecological bag includes a protective bag, soil, and grass seeds. The soil is placed inside the protective bag, and the grass seeds are placed in the soil. The grass seeds in multiple ecological bags of the aforementioned retaining wall structure grow to form a green ecological slope for the aforementioned wall panel.

[0014] Optionally, the protective bag is made of polypropylene or polyester fiber using a needle-punched nonwoven fabric process.

[0015] Optionally, it also includes a connecting structure, which is disposed between two adjacent ecological bags, and is used to fix the two adjacent ecological bags together.

[0016] Optionally, the connection structure includes a connecting plate and at least two triangular connecting parts. The connecting plate is disposed between two adjacent ecological bags, and the at least two triangular connecting parts are respectively disposed on both sides of the connecting plate. The triangular connecting parts can be inserted into the ecological bags.

[0017] Optionally, it also includes a reinforced base layer, which is laid on the ground, and multiple layers of the retaining wall structure are set on the reinforced base layer for support and drainage.

[0018] The beneficial effects of this invention are:

[0019] This invention provides an eco-bag reinforced retaining wall. Each layer of the retaining wall structure consists of eco-bags wrapped around and reinforced with reinforcing members to form a fixed layer, laid between two adjacent fill layers to protect the soil. Specifically, the soil pressure comes from the self-weight of the fill layer and the load from above. When this soil pressure acts on the wall panel, it is transmitted to the fixed layer of the reinforcing members wrapped in the eco-bags. This creates friction between the fixed layer and the fill layer, which in turn acts on the reinforcing members, thus securing the fill layer to the fixed layer. This ensures the stability of both the wall panel and the soil, resulting in high structural strength and stability, achieving its structural protection function. Furthermore, the wall panel is constructed from stacked eco-bags, allowing for greening and beautifying the environment. The eco-bags are also lightweight, thin, high-strength, and soft, possessing strong resistance to deformation, high self-healing properties, and corrosion resistance. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0033] The following reference Figures 1 to 4 This invention introduces the eco-bag reinforced retaining wall provided by the present invention. It should be noted that the vertical direction in this embodiment is... Figures 1 to 3 In the Z direction, the first horizontal direction in this embodiment is Figure 2 In the X direction, the second horizontal direction in this embodiment is Figure 1 and Figure 3 In the equation, the Y direction, X direction, and Z direction are all perpendicular to each other.

[0034] This embodiment provides an eco-bag reinforced retaining wall to prevent natural disasters such as landslides and collapses from damaging the pipeline, while also taking into account soil and water conservation functions, beautifying the ecological environment, and achieving good greening effects.

[0035] Please refer to Figure 1 and Figure 2Specifically, the eco-bag reinforced retaining wall includes a multi-layer retaining wall structure 10, which is stacked vertically on one side of the soil body 2 to form a sloped wall panel; the soil body 2 includes multiple layers of fill soil 201 stacked vertically; the retaining wall structure 10 includes tie rods 12 and multiple eco-bags 11, which are used to green the soil body 2. The multiple eco-bags 11 are stacked horizontally, and at least one layer of the multiple eco-bags 11 is laid vertically, with the first horizontal direction and the vertical direction being perpendicular to each other; the tie rods 12 cover the outer periphery of the multiple eco-bags 11, and the side of the tie rods 12 away from the eco-bags 11 forms a fixing layer to be laid and fixed between two adjacent fill soil layers 201.

[0036] In this embodiment, the eco-bag reinforced retaining wall protects the soil 2 by wrapping each layer of retaining wall structure 10 with eco-bags 11 and reinforcing members 12 to form a fixed layer between two adjacent fill layers 201. Specifically, the pressure on the soil 2 comes from the self-weight of the fill layer 201 and the load above. After the soil 2 pressure acts on the wall panel, it is transmitted to the fixed layer of the reinforcing members 12 wrapped with eco-bags 11 through the reinforcing members 12. This generates friction between the fixed layer and the fill layer 201, and the friction reacts on the reinforcing members 12, thus fixing the fill layer 201 to the fixed layer of the reinforcing members 12. This keeps the wall panel and the soil 2 stable, with high structural strength and good stability, achieving its structural protection function. Furthermore, the wall panel is also made of stacked eco-bags 11, which allows for greening of the wall panel and beautifies the ecological environment. The Eco-bag 11 is also lightweight, thin, strong, and soft, while also possessing strong resistance to deformation, high self-healing properties, and corrosion resistance.

[0037] It should be noted that as long as the friction between the fixing layer of the tie member 12 and the backfill layer 201 is greater than the pressure of the tie member 12, the tie member 12 can be stably connected to the soil 2.

[0038] Please refer to Figure 3 Specifically, the tie member 12 is folded to form two reinforcing layers 121. The first reinforcing layer 121 is laid between two adjacent fill layers 201, and the second reinforcing layer 121 is wrapped around the eco-bag 11 and fixedly connected to the first reinforcing layer 121. By setting up two reinforcing layers 121, not only can the eco-bag 11 be fixed and the structure strengthened, but the structural strength of the reinforcing layer 121 is also increased, and the friction area between it and the fill layer 201 is increased.

[0039] To ensure that the frictional force between the tie member 12 and the backfill layer 201 is greater than the pressure of the tie member 12, the tie member 12 may be made of a material with high surface roughness, certain strength, and elasticity. The high surface roughness ensures sufficient friction between the tie member 12 and the backfill layer 201, the high strength ensures the tie member 12 is not easily pulled out of the soil 2, and the high elasticity ensures the tie member 12 is not easily broken, with a deformation degree comparable to that of the soil 2.

[0040] Optionally, the tie rod 12 can be a geogrid, which is commonly used in civil engineering. It has characteristics such as high tensile strength, high deformation resistance, and excellent durability, and is easy to construct, process, and install. At the same time, it can enhance soil stability and prevent soil erosion.

[0041] Specifically, the retaining wall structure 10 includes multiple binding members 13, which are distributed along the first horizontal direction. The binding members 13 are used to bind and fix the first reinforcing layer 121 and the second reinforcing layer 121. The fixing effect between the first reinforcing layer 121 and the second reinforcing layer 121 is better through the fixing of multiple binding members 13.

[0042] Optionally, multiple binding members 13 distributed along the first horizontal direction are configured as binding groups, and multiple binding groups are spaced apart along the second horizontal direction, with the first horizontal direction, the second horizontal direction, and the vertical direction being mutually perpendicular. This arrangement increases the fixing points of the two reinforcing layers 121, thereby improving the connection stability between them.

[0043] Optionally, nylon rope can be used for binding, and there is no specific limitation here. Of course, in other embodiments, other binding structures such as cable ties can also be used for binding, and there is no specific limitation here.

[0044] Specifically, the ecological bag 11 includes a protective bag, soil, and grass seeds. The soil is placed inside the protective bag, and the grass seeds are placed in the soil. The grass seeds in the ecological bags 11 of the multiple retaining wall structures 10 grow, so that the wall panels form a green ecological slope. Through the above arrangement, the ecological bags 11 achieve greening and beautification of the wall panels, and have good air permeability, eliminating the need for additional drainage structures.

[0045] More specifically, the protective bag is a type of geotextile bag, generally made of geotextile materials. In this embodiment, it is specifically made of polypropylene (PP) or polyester fiber (PET) through a needle-punched nonwoven fabric process. It has the characteristics of being permeable to water but impermeable to soil, preventing soil erosion, promoting vegetation growth, and being environmentally friendly. It also has the characteristics of being resistant to ultraviolet rays, moisture, high temperatures, and extreme low temperatures. This design allows the grass roots inside the ecological bag 11 to germinate inside the bag or take root outside, which is very beneficial to plant growth.

[0046] Please refer to Figure 3 and Figure 4 Specifically, the eco-bag reinforced retaining wall also includes a connecting structure 20, which is set between two adjacent eco-bags 11. The connecting structure 20 is used to fix the two adjacent eco-bags 11 together, thereby strengthening the connection between the eco-bags 11 and making the wall panel connection stable.

[0047] Specifically, the connecting structure 20 includes a connecting plate 21 and at least two triangular connecting portions 22. The connecting plate 21 is disposed between two adjacent eco-bags 11, and the at least two triangular connecting portions 22 are respectively disposed on both sides of the connecting plate 21. The triangular connecting portions 22 can be inserted into the eco-bags 11. By inserting the triangular connecting portions 22 into the eco-bags 11, the connection between the connecting structure 20 and the eco-bags 11 is achieved, and the connection effect is better and the connection stability is higher.

[0048] Furthermore, the eco-bag reinforced retaining wall also includes a reinforced bottom layer 30, which is laid on the ground 1. The multi-layer retaining wall structure 10 is set on the reinforced bottom layer 30 for support and drainage. The reinforced bottom layer 30 provides support and connection between the foundation and the retaining wall structure 10, and also enables bottom drainage of the upper retaining wall structure 10.

[0049] Please refer to Figure 1 Specifically, the reinforced base layer 30 includes a stone layer 31 and a protective structure 32. The fixed end of the protective structure 32 is located between the stone layer 31 and the foundation. The protective structure 32 is similar to the retaining wall structure 10, and will not be described in detail here. The stone layer 31 is formed by piles of stones such as gravel. The placement of stones increases its supporting strength, and the gaps between the stones can also facilitate drainage.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
