Description

Technical Field

[0001] This invention relates to the field of slope soil stabilization technology, and more particularly to a soil stabilization composite structure system. Background Technology

[0002] As is well known, existing soil stabilization methods or materials include the following categories: (1) Natural compaction soil stabilization, which is suitable for areas with small slopes but cannot meet the requirements of roof construction. (2) Slope netting soil stabilization, which is suitable for steep rock face slope protection netting and spraying, but cannot fix media with small particles, and the structural system after covering with soil has poor safety. (3) Ecological bag soil stabilization, which has insufficient surface refinement and poor durability. (4) Ultra-lightweight inorganic planting substrate, which is expensive, has poor stability and water retention, and cannot meet the long-term nutritional needs of plants. (5) Soil mounding, which is expensive, has difficult curved surface construction, poor corrosion resistance, and is difficult to maintain later. (6) Existing technology of cohesive formula soil, which is expensive and has not been tested in long-term practice.

[0003] Please see Figure 7 , Figure 7 The diagram shows a schematic of soil stabilization for sloping roof landscaping or slope greening. Geocell soil stabilization technology typically uses steel or concrete column piers, with ordinary steel bars or steel strands used for tie bars. Clearly, due to the highly corrosive nature of the fill soil and the harsh environment of alternating wet and dry conditions, the durability of traditional steel and reinforced concrete structures faces severe challenges and cannot meet life-cycle requirements.

[0004] Therefore, in response to the problems existing in the prior art, the designer of this invention, based on years of experience in this industry, actively researched and improved the technology, resulting in the present invention of a soil-stabilized composite structure system. Summary of the Invention

[0005] This invention addresses the shortcomings of traditional soil stabilization methods in the prior art, such as poor durability, susceptibility to corrosion, and poor structural safety, by providing a soil stabilization composite structure system.

[0006] To achieve the objective of this invention, this invention provides a soil-stabilizing composite structure system, the soil-stabilizing composite structure system comprising:

[0007] The first stainless steel box-type sleeve is set on the base plate and connected to the main concrete structure through anchor bars located under the base plate;

[0008] The FRP box-type column pier is located on the inner side of the first stainless steel box-type sleeve at one end adjacent to the base plate, and is fixedly connected to the first stainless steel box-type sleeve by stainless steel single-sided ring groove rivets.

[0009] The second stainless steel box-shaped sleeve is sleeved on the FRP box-shaped column base at the end different from the first stainless steel box-shaped sleeve, and is fixedly connected to the FRP box-shaped column base by stainless steel single-sided ring groove rivets.

[0010] The FRP tie bar has an end, and the end of the FRP tie bar is connected to the ear plate on the outside of the second stainless steel box sleeve by means of a spherical bearing.

[0011] Optionally, the FRP tie bars are used to fix the geocells to the FRP box-type column piers to form an FRP box-type column pier-FRP tie bar system.

[0012] Optionally, the second stainless steel box-type sleeve further includes a stainless steel cover plate and a stainless steel clamp node plate that forms a U-shape with the stainless steel cover plate.

[0013] Optionally, the concrete main structure is sloping, and the slope angle α is any value within the range of 0 to 90°.

[0014] Optionally, the thickness of the soil cover for the main concrete structure shall be at least 0.45m.

[0015] Optionally, the soil stabilization gravity load is applied as a uniform surface load along the soil sliding direction.

[0016] Optionally, the gravity load transmission path of the soil is as follows: the normal force is transmitted to the EPS filling and then to the main structure; the tangential force is transmitted to the column pier, then to the support, and finally to the main structure.

[0017] Optionally, shear keys are provided between the anchor bars located under the base plate.

[0018] Optionally, a stainless steel stiffening plate is provided at the connection angle between the base plate and the first stainless steel box-shaped sleeve.

[0019] In summary, the soil-stabilizing composite structure system of this invention forms an FRP box-type column pier-FRP tie bar system, which not only achieves solid upper soil cover and smooth lower drainage, but also ensures structural durability and is suitable for landscape buildings with large slopes and soil-stabilizing cover. Furthermore, it enables modular installation and the socket-type fixing connection further ensures structural safety and reliability. Attached Figure Description

[0028] Please see Figure 1 , Figure 1 The diagram shown is a schematic representation of the overall structure of the soil-stabilizing composite structure system of the present invention. The soil-stabilizing composite structure system 1 includes:

[0029] The first stainless steel box-type sleeve 11 is disposed on the base plate 12 and is connected to the concrete main structure 10 through the anchor bar 13 located under the base plate 12.

[0030] FRP (Fiber Reinforced Plastics) box-shaped column base 14, the FRP box-shaped column base 14 is located on the inner side of the first stainless steel box-shaped sleeve 11 at one end adjacent to the base plate 12, and is fixedly connected to the first stainless steel box-shaped sleeve 11 by stainless steel single-sided annular groove rivets 15.

[0031] The second stainless steel box-type sleeve 16 is sleeved on the FRP box-type column pier 14 at the end different from the first stainless steel box-type sleeve 11, and is fixedly connected to the FRP box-type column pier 14 by a stainless steel single-sided annular groove rivet 15.

[0032] FRP tie bar 17, the FRP tie bar 17 having an end 171, and the end 171 of the FRP tie bar 17 being connected to the ear plate 161 on the outside of the second stainless steel box sleeve 16 via a spherical bearing 172.

[0033] As will be readily understood by those skilled in the art, the FRP tie bar 17 is used to fix the geocell (not shown) to the FRP box-shaped column pier 14. The present invention forms an FRP box-shaped column pier-FRP tie bar system, which not only achieves solid soil cover on the upper part and smooth drainage in the lower part, but also has a durable structure and is suitable for landscape buildings with large slopes and soil stabilization. Furthermore, it can realize modular installation and the socket-type fixed connection further ensures the safety and reliability of the structure.

[0034] Please see Figure 2 , Figure 3 and in conjunction with reference Figure 1 , Figure 2 The diagram shown is a schematic of a column head node. Figure 3 The diagram shows a top view of the column head node. Clearly, the column head node of this invention is the node structure formed by the second stainless steel box-type sleeve 16 and the FRP box-type column pier 14. The second stainless steel box-type sleeve 16 further includes a stainless steel cover plate 162 and a stainless steel clamp node plate 163 that forms a U-shape with the stainless steel cover plate 162.

The FRP tie bar 17 has an end 171, and the end 171 of the FRP tie bar 17 is connected to the ear plate 161 on the outside of the second stainless steel box sleeve 16 through a spherical bearing 172.

[0036] Please see Figures 5(a) to 5(c) and in conjunction with reference Figure 1 , Figures 5(a) to 5(c) The diagram shows a soil-stabilizing composite structure system adaptable to varying slopes and thicknesses of the soil cover. This soil-stabilizing composite structure system is suitable for landscape architecture with steep slopes requiring soil stabilization. Specifically, the concrete main structure 10 is sloping, with the slope angle α ranging from 0 to 90°, and the soil cover thickness being at least 0.45m. As a specific implementation, to enhance the stability of the first stainless steel box-type sleeve 11, shear keys 18 are preferably provided between the anchor bars 13 located under the base plate 12. Simultaneously, to further strengthen the stability of the first stainless steel box-type sleeve 11 and the base plate 12, stainless steel stiffening plates 19 are preferably provided at the connection angle between the base plate 12 and the first stainless steel box-type sleeve 11.
