Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, and more specifically, to a gravity retaining wall structure for slope protection. Background Technology

[0002] In slope protection engineering, gravity retaining walls are a common and crucial protective structure, and their stability directly affects slope safety and the surrounding environment. With increasing demands for slope protection and the growing complexity of engineering environments, higher requirements are being placed on the stability of retaining wall structures. Traditional gravity retaining wall structures have gradually revealed some limitations when dealing with complex geological conditions, earth pressure, and drainage issues, making it difficult to fully meet the high stability requirements of engineering projects.

[0003] Traditional retaining walls have limited contact area and friction between the wall foundation and the soil. Under external forces such as earth pressure and water erosion, the wall foundation is prone to slippage, affecting the overall stability of the retaining wall structure. Insufficient friction and interlocking force between the retaining wall and the soil prevent the wall from effectively bonding with the soil, making it difficult to jointly withstand earth pressure and reducing the retaining wall's resistance to slippage. Furthermore, the lack of effective drainage measures inside the retaining wall allows water to accumulate, severely impacting its stability and potentially leading to tilting, cracking, or even failure. To address these problems, this device was invented. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gravity retaining wall structure for slope protection, comprising a wall foundation and a wall body, wherein the wall foundation and the wall body are connected by steel bars, the wall foundation includes at least two layers of steps, the bottom of the wall foundation is provided with anti-slip grooves, the wall body is a trapezoidal structure, the top width is smaller than the bottom width, the soil-facing side of the wall body is provided with multiple protruding structures, the interior of the wall body is provided with drainage pipes, and the soil-repellent side of the wall body is provided with a filter layer.

[0006] Furthermore, the diameter of the reinforcing bars is 9-12mm, and the spacing between adjacent reinforcing bars is 20-30cm.

[0007] Furthermore, the depth of the anti-slip groove is 15-25cm, the width is 10-20cm, and the spacing between adjacent anti-slip grooves is 30-50cm.

[0008] Furthermore, the protruding structure is a hemispherical structure with a diameter of 20-30cm and a center-to-center distance of 40-60cm between adjacent protruding structures.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The stepped foundation design and anti-slip groove design increase the contact area and friction between the foundation and the soil, significantly improving the foundation's anti-slip capability and providing a solid foundation for the stability of the retaining wall structure. The raised structure on the soil-facing side increases friction and interlocking force with the soil, allowing the wall to better integrate with the soil and jointly bear earth pressure, significantly improving anti-slip capability. Drainage pipes are installed inside the wall to effectively guide water flow and prevent water accumulation from affecting the wall's stability. A gravel filter layer is installed on the back side of the wall to prevent fine particles from the soil behind the wall from entering the drainage pipes with the water flow, clogging them, ensuring unobstructed drainage, maintaining normal drainage function, reducing the water content of the soil behind the wall, increasing the soil's shear strength, and further enhancing the stability of the retaining wall.

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See attached document Figures 1-3 This embodiment of a gravity retaining wall structure for slope protection includes a wall foundation 1 and a wall body 2. The wall foundation 1 and the wall body 2 are connected by steel bars 3. The diameter of the steel bars 3 is 9-12mm, and the spacing between adjacent steel bars 3 is 20-30cm to ensure the connection strength and integrity of the entire retaining wall structure.

[0025] See attached document Figure 1 The wall foundation 1 includes at least two steps 11, each step 11 being 30-50cm high, with a height difference of 10-20cm between adjacent steps 11. The step 11 structure effectively increases the contact area between the wall foundation 1 and the foundation soil, thereby significantly improving the anti-slip capability of the wall foundation 1. The bottom of the wall foundation 1 is provided with anti-slip grooves 12, which are 15-25cm deep and 10-20cm wide, with a spacing of 30-50cm between adjacent anti-slip grooves 12. The anti-slip grooves 12 further enhance the friction between the wall foundation 1 and the foundation soil, effectively preventing the retaining wall from slipping under soil pressure, and providing a solid foundation for the stability of the entire retaining wall structure.

[0026] See attached document Figure 1The main body of the wall 2 is a trapezoidal structure with a top width smaller than the bottom width. The soil-facing surface of the main body of the wall 2 is provided with multiple protruding structures 21. The protruding structures 21 are hemispherical with a diameter of 20-30cm. The center-to-center distance between adjacent protruding structures 21 is 40-60cm. The protruding structures 21 can increase the friction and interlocking force between the main body of the wall 2 and the soil, so that the main body of the wall 2 and the soil are better bonded together and jointly bear the soil pressure, significantly improving the anti-sliding ability of the main body of the wall 2.

[0027] Optionally, in this embodiment, the protrusion structure 21 can also be a triangular structure or a rectangular structure.

[0028] See attached document Figure 1 The interior of the main wall 2 is equipped with drainage pipes 22. These drainage pipes are made of PVC pipes with a diameter of 20-25mm and a slope of 3%-5%. A layer of drainage pipes 22 is installed every 0.8-1.2m along the wall height, with a spacing of 50-80cm between adjacent pipes. By installing multiple drainage pipes 22, water can be more effectively guided out, preventing water accumulation from affecting the stability of the wall.

[0029] See attached document Figure 1 A filter layer 23 is provided on the back side of the main body 2 of the wall. The filter layer 23 is made of gravel and has a thickness of 20-30cm. The main function of the filter layer 23 is to prevent fine particles in the soil behind the wall from entering the drainage pipe 22 with the water flow and clogging the drainage pipe 22, thereby ensuring the smooth flow of the drainage pipe 22. By effectively filtering fine particles in the water flow, the filter layer 23 can maintain the normal drainage function of the drainage pipe 22, reduce the water content of the soil behind the wall, improve the shear strength of the soil, and further enhance the stability of the retaining wall.

[0030] See attached document Figure 3 Anchor rods 4 are fixedly installed at the four corners of the bottom of the main wall 2. The anchor rods 4 are made of threaded steel bars 3, with a diameter of 20-25mm and a length of 3-5m. The bottom end of the anchor rod 4 has a conical structure and is anchored inside the slope soil. The installation of anchor rods 4 further enhances the connection strength between the main wall 2 and the soil, tightly combining the main wall 2 and the slope soil into a whole, effectively improving the overall stability of the retaining wall, enabling it to better resist the effects of earth pressure and external loads.

[0031] See attached document Figure 1 The top of the main wall 2 is provided with a capping plate 5, which is a reinforced concrete structure with a thickness of not less than 10cm. It is used to increase the stability of the top of the main wall 2, prevent the top of the main wall 2 from being deformed or damaged by external forces, protect the integrity of the main wall 2, and extend the service life of the retaining wall.

[0032] As an optional approach, the interior of the main wall structure 2 is equipped with several vertical and horizontal reinforcing ribs (not shown in the figure). These ribs are arranged perpendicularly to each other, forming a grid-like structure. The diameter of the vertical reinforcing ribs is 12-18 mm, and the diameter of the horizontal reinforcing ribs is 10-16 mm. The spacing between adjacent vertical reinforcing ribs is 30-50 cm, and the spacing between adjacent horizontal reinforcing ribs is 20-40 cm. The reinforcement improves the compressive strength and integrity of the main wall structure 2, enhancing the load-bearing capacity of the retaining wall.

[0033] In this embodiment, the stepped wall foundation 1 and anti-slip grooves 12 effectively prevent the wall foundation 1 from slipping. The trapezoidal wall body 2, the raised structure 21 on the soil-facing side, the internal reinforcing bars, and the anchor rods 4 enhance the load-bearing capacity and integrity of the wall body 2. The drainage pipes 22 and the filter layer 23 ensure the timely drainage of water behind the wall, reducing the soil moisture content and improving the soil shear strength. The top capping plate 5 protects the top of the wall and extends the service life of the retaining wall. This retaining wall structure is suitable for slope protection projects under various complex geological conditions, and has broad application prospects and significant economic and social benefits.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
