Description

Technical Field

[0001] This utility model belongs to the field of civil engineering technology, and in particular relates to a land slope protection structure. Background Technology

[0002] Masonry slope protection is a slope protection structure constructed using rubble and mortar. It features structural stability and strong erosion resistance. Its sloping design effectively disperses soil pressure, and combined with drainage holes and a filter layer, it ensures smooth drainage, prevents water seepage damage to the slope, is easy to construct, can use locally sourced materials, and is suitable for various scenarios such as rivers, reservoirs, and highways. It combines durability and economy, making it a commonly used slope protection method in engineering.

[0003] However, since most masonry slope protection structures do not have an internal drainage system, over time, seepage carrying soil particles will be lost from the joints, causing internal hollowing and potentially leading to collapse or dam failure. Therefore, improvements are needed.

[0004] Based on this, the present invention designs a land slope protection structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that most masonry slope protection structures do not have an internal drainage system. Over time, seepage carrying soil particles can cause them to leak out from the joints, leading to internal hollowing and the potential risk of collapse or dam failure. Therefore, this utility model proposes a land slope protection structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A land slope protection structure includes a first reinforcing dam, a second reinforcing dam on one side of the first reinforcing dam, and a third reinforcing dam on one side of the second reinforcing dam. A first drainage pipe is fixedly installed inside the first reinforcing dam, and a first filter screen is fixedly installed at the top of the first drainage pipe corresponding to the top of the first reinforcing dam. A second drainage pipe is fixedly installed inside the second reinforcing dam, and a second filter screen is fixedly installed at the top of the second drainage pipe corresponding to the top of the second reinforcing dam. Transverse drainage pipes are fixedly installed inside the first, second, and third reinforcing dams, and the positions of the first and second drainage pipes correspond to the positions of the transverse drainage pipes. A drainage outlet is opened on one side of the transverse drainage pipe corresponding to the side of the third reinforcing dam.

[0008] As a further description of the above technical solution:

[0009] The first reinforcing dam has multiple first installation slots inside, and the second reinforcing dam has multiple second installation slots inside. Reinforcing steel bars are fixedly installed inside the first installation slots, and the positions of the reinforcing steel bars correspond to the positions of the second installation slots.

[0010] As a further description of the above technical solution:

[0011] A first tensile steel bar is fixedly installed on one side of the first reinforced dam, corresponding to the middle of the second reinforced dam, and a second tensile steel bar is fixedly installed on one side of the second reinforced dam, corresponding to the middle of the third reinforced dam.

[0012] As a further description of the above technical solution:

[0013] The top of the first reinforced dam is symmetrically fixed with multiple first water-following blocks, and the top of the first reinforced dam is fixed with a first masonry inclined slope protection corresponding to the top of the second reinforced dam.

[0014] As a further description of the above technical solution:

[0015] The top of the second reinforced dam is fixedly installed with a second masonry inclined slope corresponding to the top of the third reinforced dam, and a fixed platform is provided on one side of the top of the second reinforced dam corresponding to the first masonry inclined slope.

[0016] As a further description of the above technical solution:

[0017] The top of the fixed platform is symmetrically fixed with second water-following blocks at multiple locations, and the surface of the first masonry slope protection is covered with limestone.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting up a first drainage pipe, a second drainage pipe, and a transverse drainage pipe, when the land slope protection structure encounters rainy weather, a large amount of rainwater enters the interior of the transverse drainage pipe through the first and second drainage pipes, and is discharged from the dam body through the transverse drainage pipe, so as to quickly discharge the rainwater flowing down the masonry slope protection in a timely manner, reducing the impact of rainwater on the next level of masonry slope protection. When the slope seepage is large, the first and second drainage pipes can be used as a supplement to the drainage holes, avoiding the overload of drainage holes on the slope surface and causing siltation.

[0020] 2. In this utility model, by setting a second drainage pipe and a first water-following block, when the land slope protection structure encounters rainy weather, a large amount of rainwater washes away the soil and dead branches and enters the first drainage pipe, which will block the first drainage pipe. By setting a first filter screen at the top of the first drainage pipe, the rainwater is collected through the symmetrical first water-following block and flows into the interior of the first drainage pipe through the first filter screen, so as to avoid sand and dead branches being washed into the interior of the first drainage pipe and extend the service life of the first drainage pipe.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides a technical solution: a land slope protection structure, including a first reinforcing dam 1, a second reinforcing dam 2 on one side of the first reinforcing dam 1, a third reinforcing dam 3 on one side of the second reinforcing dam 2, a first drainage pipe 4 fixedly installed inside the first reinforcing dam 1, a first filter screen pipe 5 fixedly installed at the top of the first drainage pipe 4 corresponding to the top of the first reinforcing dam 1, a second drainage pipe 6 fixedly installed inside the second reinforcing dam 2, a second filter screen pipe 7 fixedly installed at the top of the second drainage pipe 6 corresponding to the top of the second reinforcing dam 2, and transverse drainage pipes 8 fixedly installed inside the first reinforcing dam 1, the second reinforcing dam 2, and the third reinforcing dam 3, with the positions of the first drainage pipe 4 and the second drainage pipe 6 corresponding to the positions of the transverse drainage pipes 8, and a drainage outlet 9 opened on one side of the transverse drainage pipe 8 corresponding to the side of the third reinforcing dam 3.

[0028] The specific implementation method is as follows: a first mounting groove 10 is provided in multiple places inside the first reinforcing dam 1, and a second mounting groove 11 is provided in multiple places inside the second reinforcing dam 2. A reinforcing steel bar 12 is fixedly installed inside the first mounting groove 10, and the position of the reinforcing steel bar 12 corresponds to the position of the second mounting groove 11.

[0029] By setting up a second mounting groove 11 and reinforcing bars 12, and by installing multiple reinforcing bars 12 in corresponding positions to the second mounting groove 11, the plastic deformation capacity of the reinforcing bars 12 can absorb seismic energy and prevent brittle failure of the masonry structure. The mesh of multiple reinforcing bars 12 can effectively disperse local stress and water flow impact, reducing the risk of masonry cracking.

[0030] The specific implementation method is as follows: a first tensile steel bar 13 is fixedly installed on one side of the first reinforcing dam 1 corresponding to the middle of the second reinforcing dam 2, and a second tensile steel bar 14 is fixedly installed on one side of the second reinforcing dam 2 corresponding to the middle of the third reinforcing dam 3.

[0031] By setting the first tensile reinforcement 13 and the second tensile reinforcement 14, the ductility of the first tensile reinforcement 13 and the second tensile reinforcement 14 can absorb the energy of earthquakes, blasting or vehicle vibrations, and prevent the brittle collapse of the masonry slope. The first tensile reinforcement 13 and the second tensile reinforcement 14 can effectively make up for the defect of low tensile strength of stone, and significantly improve the crack resistance, overall stability and durability of the slope.

[0032] The specific implementation method is as follows: a first water-following block 15 is symmetrically fixedly installed at multiple locations on the top of the first reinforcing dam 1, and a first masonry inclined slope protection 16 is fixedly installed on the top of the first reinforcing dam 1 corresponding to the top of the second reinforcing dam 2.

[0033] By setting up the first drainage block 15 and the first masonry inclined slope 16, this land slope protection structure allows rainwater to accumulate through the symmetrical first drainage blocks 15 at the top of the first masonry inclined slope 16 during rainy weather. The rainwater then flows into the interior of the first drainage pipe 4 through the first filter pipe 5. The accumulated water inside the slope generates lateral water pressure, increasing the risk of landslides. The first drainage block 15, by collecting water, allows for rapid drainage, reduces soil moisture content, and improves shear strength.

[0034] The specific implementation method is as follows: a second masonry inclined slope 17 is fixedly installed on the top of the second reinforced dam 2 corresponding to the top of the third reinforced dam 3, and a fixed platform 18 is provided on the side of the top of the second reinforced dam 2 corresponding to the first masonry inclined slope 16.

[0035] By setting up a second masonry slope protection 17 and a fixed platform 18, the surfaces of the second masonry slope protection 17 and the fixed platform 18 are dense, which can effectively resist the long-term scouring of water flow from rivers, reservoirs, etc., reduce soil erosion, and compared with rigid concrete structures, masonry has a certain degree of flexibility, can adapt to slight foundation settlement or frost heave deformation, and is not easy to crack.

[0036] The specific implementation method is as follows: multiple second water-following blocks 19 are symmetrically fixedly installed on the top of the fixed platform 18, and limestone 20 is provided on the surface of the first masonry inclined slope protection 16.

[0037] By setting the first masonry inclined slope protection 16 and quartz blocks 20, the quartz blocks 20 on the surface of the first masonry inclined slope protection 16 have well-developed micropores, and cement mortar can effectively penetrate to form mechanical interlocking. In addition, quartz blocks 20 can be coated with silane impregnating agent in acid rain areas to reduce the erosion rate.

[0038] Working principle and usage: When rainwater occurs, the water first collects through the first drainage block 15 at the top of the first reinforcing dam 1, and then flows into the interior of the first drainage pipe 4 through the first filter screen pipe 5 at the top of the first drainage pipe 4. The surface rainwater washes large pieces of gravel or dead branches into the interior of the first drainage pipe 4. The rainwater entering the first drainage pipe 4 is discharged from the dam body through the transverse drainage pipe 8. Timely discharge of rainwater from the dam body can significantly improve stability, prevent piping, and extend service life. Through the reinforcing steel bars 12 and the first tensile steel bars 13 fixedly installed inside the dam, the masonry slope protection is upgraded from a "gravity structure" to a "composite load-bearing structure", which is suitable for steep slopes and dynamic load environments. It can resist fatigue stress caused by repeated loads and extend service life. The first masonry inclined slope protection 16 and the second masonry inclined slope protection 17 fixedly installed at the top of the first reinforcing dam 1 and the second reinforcing dam 2 have a dense structure that effectively resists water erosion. They are suitable for river and reservoir bank protection. The stone has good weather resistance, long service life, and low maintenance cost.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
