Description

Technical Field

[0001] This invention relates to the field of protective engineering, specifically to an inverted V-shaped long slope protection structure. Background Technology

[0002] After the construction and excavation of long-distance oil and gas pipelines, the soil and water loss of sandy loam, silty soil and gravelly soil on the slopes is relatively serious, vegetation is not easy to grow, and it affects the oil and gas pipelines.

[0003] There are currently two main approaches to controlling soil erosion on long slopes: Approach 1, biological measures: This mainly refers to afforestation. However, afforestation should be tailored to local conditions. Protective forests are suitable for slopes with gullies, while trees should be planted along the erosion channels within gullies. In some areas, engineering measures should also be used in conjunction with these approaches. Approach 2, engineering measures: This involves using masonry retaining walls, concrete slope protection works, comprehensive drainage systems, and land reclamation to control soil erosion.

[0004] Option 1 involves significant terrain limitations, a long construction period, a large workforce, a long forest growth cycle, and complex engineering work, which increases project costs. If the terrain is narrow and the slope is greater than 25 degrees, artificial afforestation projects cannot be carried out due to terrain limitations.

[0005] Option 2 employs engineering measures, which are costly, environmentally unfriendly, and prone to damaging the original natural slope of the land surface during construction, resulting in exposed slopes and posing a significant risk of soil erosion during the construction and operation of the project. Summary of the Invention

[0006] The technical problem to be solved by this invention is to provide an inverted V-shaped long slope protection structure that can effectively protect the slope after excavation for long-distance oil and gas pipeline construction, prevent soil and water loss, and has a short construction time and low cost.

[0007] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0008] A herringbone-shaped long slope protection structure includes multiple protection blocks evenly distributed along the length of the slope. Each protection block includes a main ditch on the slope, staggered with a pipe buried in the slope. The length of the main ditch is parallel to the length of the slope. Multiple branch ditches are formed on both sides of the main ditch, connecting to the main ditch. One branch ditch connected to the lower end of the main ditch connects to a drainage ditch on the slope. One end of the branch ditch connected to the drainage ditch slopes downward, while the ends of the other branch ditches, except the one connected to the drainage ditch, slope upward away from the main ditch. The main ditch includes a lower trench on the slope, and an upper trench connected to the lower trench is formed on the slope above the lower trench. The lower and upper trenches form an inverted T-shaped trench. The lower trench is filled with multiple eco-bags, and multiple eco-bags are stacked on both sides of the upper trench, forming a main trench between the eco-bags on both sides of the upper trench. The branch ditches include placement trenches on the slope, in which eco-bags are placed.

[0009] Specifically, the placement trough includes a bottom trough opened on the slope, which is filled with ecological bags. A middle trough is opened on the slope above the bottom trough and connected to it. The middle trough is filled with ecological bags. The upper end of the ecological bags in the middle trough corresponding to the main trough is pressed into a pressing groove. A top trough is opened on the slope above the middle trough. The top troughs on both sides of the pressing groove are filled with ecological bags. The pressing groove is connected to the main trough.

[0010] Specifically, each of the two adjacent eco-bags in the bottom groove has a protrusion at its opposite end, and the two adjacent protrusions are staggered vertically and overlap vertically.

[0011] Specifically, the ecological bags in the middle trough, the bottom trough, and the top trough are stacked in a tile-like manner.

[0012] Specifically, the placement trough is a right-angled trough opened on the slope. Two layers of ecological bags are stacked in the right-angled trough. The lower layer of ecological bags protrudes to the outside of the right-angled trough. Soil is filled between the ecological bag part protruding to the outside of the right-angled trough and the slope. The slope above the right-angled trough is connected to the right-angled trough by an upslope transition. A downslope is set on the soil filled between the slope and the ecological bag part protruding to the outside of the right-angled trough. The downslope is connected to the slope. A reserved trough is set between the upper layer of ecological bags and the upslope. The slope of the upslope and the downslope are both 1:1. The reserved trough is connected to the main trough.

[0013] Specifically, the placement trough is a right-angle trough, in which two layers of ecological bags are stacked. The slope above the right-angle trough is connected to the right-angle trough by an uphill transition, with an uphill slope of 1:1. The lower layer of ecological bags is the same length as the lower wall of the right-angle trough, and a reserved trough is provided between the upper layer of ecological bags and the uphill slope, which is connected to the main trough.

[0014] Specifically, the placement trough is a groove opened on the slope, and two layers of ecological bags are stacked in the groove. The slope above the groove is connected to the groove through an uphill transition. The slope of the uphill is 1:1. The lower layer of ecological bags is the same length as the lower wall of the groove. A reserved groove is set between the upper layer of ecological bags and the uphill, and the reserved groove is connected to the main trough.

[0015] Specifically, the ecological bag includes a bag body with multiple gripping cones fixed to its lower end. The bag opening is connected by a snap fastener. A fertilizer bag is placed inside the bag. Above the fertilizer bag, the bag body is filled with a planting soil layer. Above the planting soil layer, the bag body contains a plant growth layer. Multiple seeds are arranged in a rectangular array within the plant growth layer. Above the plant growth layer, a support and guide assembly is placed inside the bag body. Above the support and guide assembly, a growth-promoting component is installed inside the bag body. The support and guide assembly includes two inverted L-shaped support plates. A first connecting plate is installed above each row of seeds. Multiple first connecting plates are located between two support plates. Inclined plates are fixed on both sides of the first connecting plates. The upper ends of adjacent inclined plates are fixedly connected, forming a conical structure. The support plate is fixedly connected to the upper end of one of its inclined plates. The first connecting plate has through holes corresponding to the seeds. The upper ends of the support plates all have long grooves. The growth-promoting component includes a second connecting plate located above the support plate. The second connecting plate has a sliding plate corresponding to the long groove, which is vertically set and slides through the long groove to connect with the support plate. The second connecting plate has a through groove corresponding to the through hole, and the upper end of the bag has a water hole corresponding to the through groove. The lower end of the second connecting plate above the inclined plate is fixed with an elastic sheet, and the lower end of the elastic sheet is fixed with an arc plate. The arc plates on both sides of the through hole are bent towards the middle of the through hole. One of the arc plates has a blind hole corresponding to the through hole at its lower end, and a germination sac is fixed in the blind hole. The germination sac is filled with a germination agent. The lower end of the other arc plate is fixed with a tip corresponding to the germination sac. During the downward movement of the second connecting plate, under the guidance of the inclined plate, the lower ends of the arc plates on both sides of the through hole can approach each other, and the elastic sheet undergoes elastic deformation. The tip of one arc plate can pierce the germination sac in the blind hole at the lower end of the other arc plate, so that the germination agent in the germination sac drips onto the seeds in the plant growth layer.

[0016] Specifically, the bag body, fertilizer bag, and plant growth layer are all woven from polyester fibers.

[0017] Specifically, the catalyst is a gibberellin solution with a concentration of 10-15 mg / L.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention effectively prevents soil erosion on slopes, is not easily restricted by terrain, is simple to construct, and has low cost. It does not cause secondary damage to the original slope, and the tributary ditches and main ditches form an inverted V-shaped structure system, making it safer and more reliable.

[0020] 2. The ecological bag is equipped with a germination bladder. After the ecological bag is set up, you can tap the ecological bag to allow the germination agent in the bladder to flow onto the seeds, which can improve the seed survival rate.

[0021] 3. Since seedlings are relatively fragile when they first germinate, separating the fertilizer bag from the plant growth layer with the planting soil can prevent the seedlings from directly contacting the fertilizer and burning them. After the seedlings have grown for a period of time and become strong enough, their roots will gradually come into contact with the fertilizer bag, reducing the risk of seedling burn and ensuring the survival rate of the seedlings.

[0037] Example 1:

[0038] like Figures 1-4 As shown, an inverted V-shaped long slope protection structure includes multiple protection blocks set on the slope surface 101, with the multiple protection blocks evenly distributed along the length direction of the slope surface 101.

[0039] The protected area includes a main ditch 103 excavated on a slope 101, which is offset from the pipe 102 buried in the slope 101. The length of the main ditch 103 is parallel to the length of the slope 101. Multiple branch ditches 104 are excavated on both sides of the slope 101 of the main ditch 103. The branch ditches 104 are connected to the main ditch 103. One branch ditches 104 connected to the lower end of the main ditch 103 is connected to a drainage ditch on the slope 101. One end of the branch ditches 104 connected to the drainage ditch slopes downward. Except for the branch ditches 104 connected to the drainage ditch, the other branch ditches 104 slope upward at the end away from the main ditch 103.

[0040] The dry ditch 103 includes a lower trough 106 opened on the slope 101. An upper trough 105 connected to the lower trough 106 is opened on the slope 101 above the lower trough 106. The lower trough 106 and the upper trough 105 form an inverted T-shaped trough. The lower trough 106 is filled with multiple ecological bags 107. Multiple ecological bags 107 are stacked on both sides of the upper trough 105. The main trough 108 is formed between the ecological bags 107 on both sides of the upper trough 105.

[0041] The tributary ditch 104 includes a placement trough opened on the slope 101, and an ecological bag 107 is placed in the placement trough.

[0042] The placement trough includes a bottom trough 109 formed on the slope 101, and the bottom trough 109 is filled with ecological bags 107. Each of the opposite ends of two adjacent ecological bags 107 in the bottom trough 109 is provided with a protrusion 1071, and the two adjacent protrusions 1071 are staggered vertically and overlap vertically.

[0043] A middle trough 110, connected to the slope 101 above the bottom trough 109, is formed, and is filled with eco-bags 107. The upper end of the eco-bags 107 in the middle trough 110, corresponding to the main trough 108, is pressed into a groove 112. A top trough 111, also located on the slope 101 above the middle trough 110, is filled with eco-bags 107 on both sides of the groove 112. The groove 112 is connected to the main trough 108.

[0044] The eco-bags 107 in the middle trough 110, the eco-bags 107 in the bottom trough 109, and the eco-bags 107 in the top trough 111 are stacked in a corrugated manner.

[0045] When it rains, rainwater on the slope 101 can enter the main channel 108 and the pressure channel 112, and the ecological bag 107 can reduce water leakage. Rainwater in the main channel 108 and the pressure channel 112 can be discharged through the drainage channel on the slope 101.

[0046] Example 2:

[0047] like Figure 5 As shown, the placement trough is a right-angled trough 114 formed on the slope 101. Two layers of ecological bags 107 are stacked inside the right-angled trough 114. The lower layer of ecological bags 107 protrudes beyond the outside of the right-angled trough 114, and soil is filled between the protruding portion of the ecological bags 107 and the slope 101. The slope 101 above the right-angled trough 114 is connected to the right-angled trough 114 via an upslope 115. A downslope 116 is provided on the soil filling between the slope 101 and the portion of the ecological bags 107 protruding beyond the right-angled trough 114, and the downslope 116 is connected to the slope 101. A reserved trough is provided between the upper layer of ecological bags 107 and the upslope 115, and the reserved trough is connected to the main trough 108. The slopes of the upslope 115 and the downslope 116 are both 1:1.

[0048] In this embodiment, when laying the branch ditch 104, only a right-angle groove 114 needs to be opened on the slope 101, and two layers of ecological bags 107 need to be stacked in the right-angle groove 114. The laying process of the branch ditch 104 is simpler and the cost is lower.

[0049] Example 3:

[0050] like Figure 6 As shown, the placement groove is a right-angled groove 114, in which two layers of ecological bags 107 are stacked. The slope 101 above the right-angled groove 114 is connected to the groove via an upslope 115. The lower layer of ecological bags 107 is the same length as the lower wall of the right-angled groove 114, and a reserved groove is provided between the upper layer of ecological bags 107 and the upslope 115, which is connected to the main groove 108. The slope of the upslope 115 is 1:1.

[0051] Compared to Embodiment 2, in this embodiment, when laying the branch ditch 104, the ecological bag 107 is supported by the lower wall of the right-angle groove 114, and the ecological bag 107 has better stability. There is no need to fill the soil between the ecological bag 107 and the slope 101, and there is no need to set up the downslope 116, which further simplifies the laying process of the branch ditch 104.

[0052] Example 4:

[0053] like Figure 7 As shown, the placement groove is a recess 113 formed on the slope 101. Two layers of ecological bags 107 are stacked in the recess 113. The slope 101 above the recess 113 and the recess 113 are connected by an upper slope 115. The lower layer of ecological bags 107 is the same length as the lower wall of the recess 113. A reserved groove is provided between the upper layer of ecological bags 107 and the upper slope 115, and the reserved groove is connected to the main groove 108. The slope of the upper slope 115 is 1:1.

[0054] In this embodiment, by placing the eco-bag 107 in the groove 113, the eco-bag 107 has better stability and can improve the impact resistance of the eco-bag 107.

[0055] Example 5:

[0056] like Figures 8-13 As shown, the ecological bag 107 includes a bag body 1, with multiple gripping cones 3 fixed to the lower end of the bag body 1. The bag opening of the bag body 1 is connected by a snap fastener 2. A fertilizer bag 5 is placed inside the bag body 1. A planting soil layer 6 is filled inside the bag body 1 above the fertilizer bag 5. A plant growth layer 7 is placed inside the bag body 1 above the planting soil layer 6. Multiple seeds 8 are arranged in a rectangular array inside the plant growth layer 7. The bag body 1, fertilizer bag 5, and plant growth layer 7 are all woven from polyester fibers.

[0057] A support and guide assembly is placed inside the bag 1 above the plant growth layer 7. A growth-promoting assembly is set inside the bag 1 above the support and guide assembly. The support and guide assembly includes two inverted L-shaped support plates 18. A first connecting plate 9 is set above each row of seeds 8. Multiple first connecting plates 9 are located between the two support plates 18. Inclined plates 10 are fixed on both sides of the first connecting plate 9. The upper ends of two adjacent inclined plates 10 are fixedly connected. The two adjacent inclined plates 10 form a conical structure. The upper ends of the support plate 18 and the inclined plate 10 on one side are fixedly connected. The first connecting plate 9 has through holes 11 corresponding to the seeds 8. The upper ends of the support plates 18 are all provided with long grooves 19.

[0058] The growth-promoting component includes a second connecting plate 12 located above the support plate 18. A sliding plate 13 corresponding to the long groove 19 is fixed to the second connecting plate 12. The sliding plate 13 is vertically positioned, passes through the long groove 19, and is slidably connected to the support plate 18. A through groove 14 corresponding to the through hole 11 is formed on the second connecting plate 12. A water hole 4 corresponding to the through groove 14 is formed at the upper end of the bag body 1. Elastic sheets 16 are fixed to the lower ends of the second connecting plate 12 above the inclined plate 10. Arc-shaped plates 15 are fixed to the lower ends of the elastic sheets 16. The arc-shaped plates 15 on both sides of the through hole 11 are bent towards the center of the through hole 11. One arc-shaped plate 15 has a blind hole corresponding to the through hole 11 at its lower end. A growth-promoting capsule 17 is fixed inside the blind hole, and the growth-promoting capsule 17 contains a growth-promoting agent, which is a gibberellin solution with a concentration of 10-15 mg / L. A pointed portion corresponding to the growth-promoting capsule 17 is fixed to the lower end of the other arc-shaped plate 15.

[0059] During the downward movement of the second connecting plate 12, under the guidance of the inclined plate 10, the lower ends of the arc-shaped plates 15 on both sides of the through hole 11 can approach each other, and the elastic sheet 16 undergoes elastic deformation. The tip 20 of one arc-shaped plate 15 can pierce the germination sac 17 in the blind hole at the lower end of the other arc-shaped plate 15, thereby causing the germination agent in the germination sac 17 to drip onto the seeds 8 in the plant growth layer 7.

[0060] After the ecological bag 107 is laid in the designated position, the gripping cone 3 should be laid downwards. After laying, the upper surface of the bag body 1 should be slapped to make the second connecting plate 12 move downwards. During the downward movement of the second connecting plate 12, under the guidance of the inclined plate 10, the lower ends of the arc plates 15 on both sides of the through hole 11 can approach each other, and the elastic sheet 16 undergoes elastic deformation. The tip of one arc plate 15 can pierce the germination sac 17 in the blind hole at the lower end of the other arc plate 15, so that the germination agent in the germination sac 17 can flow through the through hole 11 to the top of the plant growth layer 7. Finally, under the action of gravity, it penetrates into the plant growth layer 7 and comes into contact with the seeds 8, thereby accelerating the germination of the seeds 8.

[0061] After the tapping on the upper surface of the bag 1 stops, the arc-shaped plate 15 and the second connecting plate 12 will return to their initial positions under the elastic action of the elastic sheet 16. Finally, water is poured onto the bag 1. The water will drip through the water hole 4 and the through groove 14, and guided by the arc-shaped plate 15, through the through hole 11 onto the plant growth layer 7, and then seep into the interior of the plant growth layer 7 to contact the seeds 8, thereby accelerating the germination of the seeds 8.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
