Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundations, and more specifically, relates to a slope drainage anti-slide pipe pile structure. Background Technique

[0002] In the face of complex and changeable geological environments, especially those areas with rich groundwater reserves and potential risks of shallow landslides, constructing stable and fully functional engineering structures has become an extremely challenging task. The geological conditions in these areas are complex, with a high groundwater level, large soil moisture content, and the existence of landslide risks, which pose extremely high requirements for any structural design aimed at strengthening slopes or preventing landslides.

[0003] Traditionally, anti-slide structures such as retaining walls and anchor support systems have shown good performance in dealing with general geological conditions. However, in special sections with rich groundwater and accompanied by shallow landslide risks, these structures often face dual challenges: on the one hand, they need sufficient strength and stiffness to resist the huge thrust generated by landslides to ensure the safety of the structure itself and the protected area; on the other hand, they must effectively solve the problem of groundwater accumulation, because the rising groundwater level will not only increase the weight of the soil mass, reduce the internal friction angle of the soil, thus exacerbating the landslide risk, but also may erode the structure foundation, affecting its long-term stability.

[0004] Traditional drainage measures, such as blind ditches and drainage holes, although can relieve groundwater pressure to a certain extent, but under high water levels and complex geological conditions, their drainage efficiency is limited, and they are easily affected by blockages and difficult to work effectively for a long time. At the same time, these measures are often relatively independent of the design of anti-slide structures and fail to form a synergistic effect, resulting in an unsatisfactory overall protection effect. Content of the Utility Model

[0005] The purpose of the embodiment of this application is to provide a slope drainage anti-slide pipe pile structure to solve the technical problem of difficult support in sections with rich groundwater and accompanied by shallow landslide risks in the prior art.

[0006] To achieve the above purpose, the technical solution adopted in this application is:

[0007] Provide a slope drainage anti-slide pipe pile structure, including:

[0008] A sunk platform, located at the foot of the slope;

[0009] A group of pipe piles, including a plurality of hollow sinking pipes, the hollow sinking pipes are assembled vertically on the sunk platform and extend below the sunk platform, and one end of each hollow sinking pipe is flush with the top surface of the sunk platform; each of the hollow sinking pipes is arranged at intervals from each other;

[0010] A permeable layer, located below the sunken platform and filled between the hollow caissons;

[0011] At least one side of the sunken platform and / or the permeable layer is supported on the vertical section of the slope.

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

[0013] Optionally, the sunken platform has caisson insertion holes and permeable layer pouring holes. The number of caisson insertion holes corresponds to the number of hollow caissons, and the number of permeable layer pouring holes is multiple. Each permeable layer pouring hole is arranged at intervals.

[0019] This application provides a slope drainage anti-slide pipe pile structure, including a sunken platform, a pipe pile group, and a permeable layer. Among them, the sunken platform is located at the foot of the slope. The pipe pile group includes a plurality of hollow caissons. The hollow caissons are assembled vertically on the sunken platform and extend below the sunken platform, and one end of the hollow caisson is flush with the top surface of the sunken platform; the hollow caissons are arranged at intervals.

[0033] As Figures 1 to 3 shown, the present application provides a slope drainage anti-sliding pipe pile structure, which includes a sunk platform 1, a pipe pile group, and a permeable layer 3. Among them, the sunk platform 1 is located at the foot of the slope 4. The pipe pile group includes a plurality of hollow sinking pipes 2, and the hollow sinking pipes 2 are assembled vertically on the sunk platform 1 and extend below the sunk platform 1, and one end of the hollow sinking pipe 2 is flush with the top surface of the sunk platform 1; the hollow sinking pipes 2 are arranged at intervals from each other. The hollow channels in the hollow sinking pipes 2 can be used as drainage channels without the need to additionally arrange drainage pipes. The hollow sinking pipes 2 and the sunk platform 1 are assembled and connected, thereby shortening the construction time of the slope drainage anti-sliding pipe pile structure, and are particularly suitable for scenarios such as highway emergency rescue that require rapid traffic restoration. The permeable layer 3 is located below the sunk platform 1 and fills the space between the hollow sinking pipes 2, which not only effectively increases the weight of the entire structure and enhances its ability to resist landslide thrust, but also further promotes the discharge of groundwater through its permeability, reduces the water content of the slope soil body, and thus improves the stability of the slope.

[0034] As Figures 1 to 3 shown, in an embodiment of the present application, the sunk platform 1 has a pipe sinking insertion hole 11 and a permeable layer pouring hole 12. The number of the pipe sinking insertion holes 11 corresponds to the number of the hollow sinking pipes 2 to ensure that each hole position can correspond to the hollow sinking pipe 2 to be installed one by one. The number of the permeable layer pouring holes 12 is multiple, and the permeable layer pouring holes 12 are arranged at intervals from each other. This not only ensures that the permeable layer 3 can fully cover and effectively penetrate into the required area, but also avoids problems such as material waste and uneven structural strength caused by too dense pouring holes.

[0035] In an embodiment of the present application, the sunk platform 1 is a precast sunk platform. The adoption of the precast sunk platform 1 means that most of the processing and assembly work of the structure has been completed in the factory, including dimension control, selection of high-strength materials, and necessary pre-reinforcement treatment, ensuring that the design requirements are met at the time of leaving the factory. When the precast sunk platform 1 is transported to the construction site, only simple positioning, installation, and connection operations are required, and it can be quickly integrated into the overall engineering structure, greatly reducing the amount of on-site wet work and avoiding the impact of weather, environment and other factors on the construction progress. In addition, the application of the precast sunk platform 1 also promotes the standardization and normalization of the construction process, reduces the technical difficulty and risk of on-site operations, and improves the construction quality and safety.

[0036] As Figures 1 to 3As shown, in an embodiment of the present application, the hollow caissons 2 are arranged on the caisson platform 1 in a rectangular array, which not only makes full use of the bearing area of the caisson platform 1, but also ensures an equal spacing between the hollow caissons 2, thereby optimizing the overall stability and mechanical properties of the structure.

[0037] In an embodiment of the present application, the hollow caisson 2 is a prestressed pipe pile. The prestressed pipe pile, with its unique prestressing technology, has a strong compressive and flexural resistance even before being subjected to external forces during the manufacturing process through the tension of internal steel bars and the high-pressure pouring of concrete. Applying the prestressed pipe pile to the hollow caisson 2 can not only effectively improve the bearing capacity of the overall structure, resist the erosion and deformation of the external environment, but also maintain stable performance during long-term use. During the construction process, the superiority of the prestressed pipe pile as the hollow caisson 2 is fully demonstrated. Its good drivability enables the caisson to easily penetrate various geological layers, reducing the construction difficulty and cost. At the same time, the prestressed pipe pile has a fast pile driving speed, which helps to shorten the construction period and improve the construction efficiency.

[0038] In an embodiment of the present application, the permeable layer 3 is a permeable concrete layer. Using permeable concrete as the construction material for the permeable layer 3 not only meets the basic requirements of the structure for permeable performance, but also ensures the stability and safety of the entire system during use due to its good strength and durability. In addition, permeable concrete is easy to construct and maintain, and can achieve good combination with other building materials such as the hollow caisson 2, further improving the quality and efficiency of the overall project. During the preparation process, parameters such as the aggregate particle size, cement dosage, and additive types of permeable concrete should be precisely controlled to achieve the best balance between porosity and strength. This material can not only maintain sufficient permeable performance but also withstand a certain load, providing strong support for constructing a high-performance permeable structure.

[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
