Description

Technical Field

[0001] This utility model relates to the field of construction, specifically a wind-resistant green slope reinforcement structure for building construction. Background Technology

[0002] In the field of building construction, slope reinforcement is a key link in ensuring project safety and ecological restoration. Especially in windy areas, slopes are prone to soil loss and structural instability under strong wind loads. Specialized reinforcement structures are needed to achieve synergy between wind resistance, slope stabilization and greening. The traditional structures currently on the market still have the following problems: First, traditional wind-resistant piles mostly adopt a smooth pile design, which has a limited interlocking area with the slope, making them prone to uplift or tilting under strong wind loads; at the same time, the connection between the pile and the upper load-bearing structure is mostly rigid welding, which lacks buffering and adjustment capabilities, and is prone to joint cracking under long-term stress; Second, in traditional structures, vegetation planting and reinforcement components such as grids and piles lack organic integration, making it difficult for vegetation roots to form deep anchorage, and the fixing method of the grid and steel beams is loose, which makes it easy for problems such as grid slippage and vegetation withering to occur under wind erosion. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wind-resistant green slope reinforcement structure for building construction. The design is as follows: wind-resistant piles are anchored to the slope through the spiral blade extension structure; the top support platform connects to a grid-shaped H-beam to form a skeleton, transferring the load to the wind-resistant piles; ecological grids are fixed between the steel beams, and the roots of wind-resistant vegetation inside penetrate the grids and penetrate deep into the slope, forming a three-dimensional reinforcement with the structure; the slope top guide plate guides the airflow to reduce wind load, and all components work together to achieve wind resistance and slope stabilization.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant green slope reinforcement structure for building construction, comprising a slope, wherein a guide plate is provided at the top of the slope, the guide plate is distributed in an arc-shaped stepped manner, and threaded holes are opened at the bottom of its arc surface, and the guide plate is connected to a slope anchoring structure by bolts; The slope stabilization and anchoring structure includes wind-resistant piles. The wind-resistant piles are cylindrical with spiral blade extensions around their perimeter. A square reinforced concrete base is cast on the top of the pile. Threaded holes are symmetrically opened on the sides of the square reinforced concrete base in the horizontal direction. The piles are connected to H-beams by high-strength bolts. The H-beams are distributed in a crisscross pattern along the slope, with their tops extending upwards to the top of the slope and connected to the bottom of a guide plate by threads. Ecological grids are laid between the intersecting H-beams. The edges of the ecological grids are fixed to the H-beams by binding. The inside of the grids is filled with planting substrate and wind-resistant vegetation is planted. The roots of the wind-resistant vegetation penetrate the ecological grids and extend deep into the slope.

[0005] Furthermore, the wind-resistant pile is provided with a PVC grouting pipe along the axial direction inside, the bottom of the grouting pipe extends to the outer structure area of ​​the spiral blade, and the top is flush with the surface of the square reinforced concrete foundation.

[0006] Furthermore, an L-shaped bracket is welded to the back of the guide plate, and a mounting hole with a diameter of 16mm is opened at the other end of the bracket, which is fixed to the top of the slope by expansion bolts.

[0007] Furthermore, the thickness of the spiral blade extension structure is 10mm, the diameter is 1.5 times the diameter of the wind-resistant pile body, and the pitch between adjacent blades is 500mm.

[0008] Furthermore, the lower part of the inner side of the arc-shaped surface of the guide plate is provided with a vent hole, the vent hole 5 has a diameter of 8mm and the opening is rounded.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. Enhanced structural synergy and significantly improved wind resistance and slope stabilization. In existing technologies, the anchoring of wind-resistant piles to the slope relies mainly on the pile's own friction, resulting in a single stress distribution and limited pull-out resistance. In contrast, this structure uses the spiral blade extension structure of the wind-resistant pile to form a multi-point engagement with the slope, combined with the support of the grid-shaped H-beam frame, to evenly transfer the slope load to the pile, greatly enhancing the overall structure's wind resistance stability and effectively resisting the risks of uplift and overturning caused by strong wind loads.

[0010] 2. This application achieves an organic integration of ecological restoration and engineering reinforcement. In traditional techniques, vegetation planting and reinforcement structures are often set up independently, resulting in low vegetation survival rates and difficulty in forming effective anchorage. This application uses ecological grids to fix the planting substrate, allowing the roots of wind-resistant vegetation to penetrate the grids and penetrate deep into the slope. Together with steel beams and wind-resistant piles, they form a three-dimensional reinforcement network. While ensuring the stability of the slope structure, this application achieves ecological restoration with the help of native vegetation, improving the slope's long-term erosion resistance and environmental compatibility.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This embodiment describes a wind-resistant green slope reinforcement structure for building construction, comprising a slope, with a guide plate 1 at the top of the slope. The guide plate 1 is distributed in an arc-shaped stepped manner, and threaded holes are opened at the bottom of its arc surface. The guide plate 1 is connected to a slope anchoring structure 2 by bolts. The slope stabilization anchorage structure 2 includes wind-resistant piles 201. The wind-resistant piles 201 are cylindrical with spiral blade extension structures 202 around their perimeter. A square reinforced concrete foundation 203 is poured on the top of the piles. The square reinforced concrete foundation 203 has threaded holes symmetrically opened on the side along the horizontal direction. It is connected to H-shaped steel beams 204 by high-strength bolts. The H-shaped steel beams 204 are distributed in a crisscross pattern along the slope, with the top extending upward to the top of the slope. They are connected to the bottom of the guide plate 1 by threads. Ecological grids 205 are laid between the intersecting H-shaped steel beams 204. The edges of the ecological grids 205 are fixed to the H-shaped steel beams 204 by binding. The inside of the grids is filled with planting substrate and wind-resistant vegetation 206 is planted. The roots of the wind-resistant vegetation 206 penetrate the ecological grids 205 and go deep into the slope.

[0015] A PVC grouting pipe 3 is installed through the axial position of the wind-resistant pile 201. The pipe body is made of UPVC material, with a diameter of 50mm and a wall thickness of 3.2mm. Its bottom end extends to the lowest point of the area where the spiral blade extension structure 202 is located, 500mm away. The top end is flush with the surface of the square reinforced concrete foundation 203. The pipe opening is equipped with a threaded sealing cap. With this built-in grouting pipe design, after the wind-resistant pile 201 is installed, cement grout can be injected into the gap between the pile body and the slope body through a high-pressure grouting pump. The grout can spread evenly along the channel of the spiral blade extension structure 202. After solidification, it forms a rigid connection of "pile body-grout-soil" as a whole, which can improve the pull-out bearing capacity of the wind-resistant pile 201, and effectively fill the pores generated during construction, greatly enhancing the overall anchoring effect.

[0016] The back of the deflector plate 1 is fixed with an L-shaped bracket 4 by full welding. The bracket is made of Q235 steel plate cut and bent. The other end of the bracket is machined with a 16mm diameter mounting hole. It is fixed to the top of the slope by M12 expansion bolts with a bolt embedment depth of not less than 100mm. This fixing method not only enhances the installation stability of the deflector plate 1 and can withstand wind loads of level 10 or above, but also disperses the wind load to the deep layers of the slope through the bracket 4, avoiding structural deformation caused by excessive stress at a single point. At the same time, it facilitates disassembly and adjustment during later maintenance.

[0017] The wind-resistant vegetation 206 uses a mixed sowing combination of sea buckthorn, alfalfa, and caragana. The seeds of the three plants are mixed in a weight ratio of 3:2:1 and are pre-germinated before sowing, with a germination rate of over 90%. In this combination, sea buckthorn, as a deep-rooted shrub, has taproots that can penetrate more than 2m into the slope to form a vertical anchor, and lateral roots that can extend horizontally up to 1.5m. Alfalfa, a legume, has densely interwoven fibrous roots that form a horizontal network and can fix nitrogen to improve the soil. Caragana has extremely strong drought resistance and wind resistance, and its branches can form a windbreak. The three plants work together to form a three-dimensional reinforcement system through their root systems, ecological grid 205, and H-shaped steel beams 204, and can achieve full slope coverage within 6 months, improving ecological restoration efficiency and reducing the direct impact of wind erosion on the slope.

[0018] The spiral blade extension structure 202 is cut and formed from Q355B steel plate. The blade thickness is set to 10mm, and the edges are rounded. The blade diameter is 1.5 times the diameter of the wind-resistant pile 201. The pitch between adjacent blades is maintained at 500mm. This parameter design can maximize the contact area between the blade and the soil. When the wind-resistant pile 201 is screwed into the slope, the blade can cut and squeeze the surrounding soil, which increases the density of the soil around the pile. Through the spiral interlocking effect, the lateral thrust generated by the wind load is dispersed to a larger area of ​​the slope, which can improve the overturning resistance of the wind-resistant pile 201 and effectively cope with the periodic load generated by strong winds.

[0019] In the lower middle part of the inner side of the arc-shaped curved surface of the guide plate 1, a row of vent holes 5 are evenly distributed along the length direction. The diameter of the vent holes 5 is 8mm, the openings are rounded, and the spacing between the holes is 150mm. This design allows some airflow to pass through the vent holes 5 to form a buffer airflow when the guide plate 1 guides the airflow around, balancing the air pressure difference on both sides of the guide plate, reducing wind resistance load, and preventing the guide plate 1 from vibrating at high frequency due to excessive wind resistance. At the same time, the rounded corner structure can effectively reduce the stress concentration phenomenon at the opening, reducing the local stress to less than 60% of the allowable stress of the material, and significantly extending the service life of the guide plate 1.

[0020] In summary, this wind-resistant green slope reinforcement structure achieves stable operation through the precise coordination of multiple components: the arc-shaped stepped guide plate at the top of the slope guides airflow smoothly along the arc surface, significantly reducing the direct impact load of strong winds on the slope; the L-shaped bracket welded to its back is firmly connected to the top of the slope with expansion bolts, effectively transferring the wind force borne by the guide plate to the deep soil of the slope, avoiding local overload; the wind-resistant piles, with their spiral blade extension structure, form a tight spiral engagement with the slope's soil and rock, and with the cement grout injected through the PVC grouting pipe at the axis, a three-in-one "pile-grout-soil" system is formed around the pile. The rigid connector significantly enhances the anchoring effect. The square reinforced concrete foundation at the top is firmly connected to the crisscrossing grid-shaped steel beams by high-strength bolts, forming a rigid skeleton covering the entire slope and evenly distributing the load borne by each area of ​​the slope to the wind-resistant piles. The ecological grid is laid within the grid formed by the steel beams and fixed to the steel beams by binding. The planting substrate filled inside provides a growth base for the mixed vegetation. The roots of sea buckthorn, alfalfa and caragana penetrate the grid and penetrate deep into the slope, intertwining with the grid and steel beams to form a three-dimensional reinforcement network. While ensuring the structural mechanical performance, the ecological restoration function is also realized simultaneously. The significant advantages of this scheme are reflected in multiple dimensions: In terms of structural stability, by using techniques such as increasing the contact area between the pile and the slope through spiral blades and strengthening the connection through grouting and anchoring, the overall structure's pull-out resistance and overturning resistance are greatly improved. Tests have shown that it can effectively withstand the long-term effects of strong winds exceeding level 10. In terms of ecological synergy, the mixed planting of vegetation not only enhances the slope reinforcement effect through its root system but also achieves slope coverage in a short time, reducing the damage to the slope caused by wind and water erosion. The deep roots of sea buckthorn, the fibrous roots of alfalfa, and the windproof properties of caragana form a protective barrier. The complementary nature of the components significantly improves the efficiency and quality of ecological restoration. In terms of construction and maintenance, the connection methods of each component are rationally designed, such as the threaded connection between the guide plate and the steel beam, and the binding and fixing of the ecological grid to the steel beam. This ensures both the strength of the connection and facilitates construction, installation, and subsequent inspection and maintenance. Simultaneously, the parameters of each structure have been optimized, such as the thickness and pitch of the spiral blades, and the diameter and spacing of the ventilation holes, ensuring the rational transmission of force and the durability of the structure. Compared to traditional slope reinforcement structures, this demonstrates a significant improvement in safety, environmental friendliness, and economy.
