Description

Technical Field

[0001] This utility model relates to the field of slope protection engineering technology, specifically to a mesh PE permeable pipe device for horizontal drainage holes on slopes. Background Technology

[0002] In the field of slope engineering, groundwater accumulation is a significant contributing factor to geological disasters such as landslides and collapses. Horizontal drainage holes, as a crucial measure to drain groundwater from within slopes and reduce the water content of soil and rock, are of great importance in ensuring slope stability. However, in the construction and application of horizontal drainage holes on slopes, traditional pipes such as galvanized steel pipes and PVC pipes often have several drawbacks: Firstly, galvanized steel pipes are susceptible to soil corrosion and have a short service life; PVC pipes have poor permeability and weak deformation resistance, and the lateral pressure of the slope soil and rock can easily cause PVC pipes to deform or even rupture, leading to drainage failure. Secondly, traditional pipes lack effective filtration structures on their surfaces and lack efficient anti-clogging designs, allowing fine particles in the soil to easily enter the pipes with groundwater, causing siltation and further hindering drainage; moreover, if the orifice is not sealed tightly, it can cause surface water backflow, exacerbating the risk of siltation inside the pipes and water erosion of the slope. Therefore, there is an urgent need for a horizontal drainage device for slopes that combines high permeability, anti-clogging, corrosion resistance, and convenient construction to solve the above-mentioned technical problems. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of existing horizontal drainage devices for slopes, such as easy corrosion, poor permeability, weak deformation resistance, insufficient anti-clogging ability, susceptibility to backflow of surface water, and inconvenience of construction. It provides a mesh PE permeable pipe device for horizontal drainage holes of slopes to ensure the long-term stable operation of the drainage device, reduce construction costs and difficulties, effectively drain groundwater inside the slope, reduce the water content of the soil and rock, thereby improving slope stability and avoiding the risk of geological disasters such as landslides and collapses.

[0004] To achieve the above objectives, this utility model provides a mesh PE permeable pipe device for horizontal drainage holes on slopes, comprising:

[0005] The main body of the mesh PE rigid permeable pipe is adapted to the aperture setting of the horizontal drainage holes on the slope. The upper half of the main body of the mesh PE rigid permeable pipe has permeable holes evenly distributed around its circumference, while the lower half of the main body of the mesh PE rigid permeable pipe has no permeable holes.

[0006] A filter layer, which is wrapped around the outer periphery of the mesh PE rigid permeable pipe body, is used to intercept fine soil particles;

[0007] An orifice sealing structure is provided at the orifice of the horizontal drainage hole on the slope, and the orifice sealing structure is arranged around the end of the mesh PE rigid permeable pipe body to seal the gap between the orifice of the horizontal drainage hole and the mesh PE rigid permeable pipe body.

[0008] Furthermore, the filter layer is geotextile, and the geotextile has two layers. The two layers of geotextile are fixed along the length of the main body of the mesh PE rigid permeable pipe by binding members.

[0009] Furthermore, the geotextile is a spunbond geotextile, the binding element is a rope, and the binding spacing of the rope along the length of the main body of the mesh PE rigid permeable pipe is no more than 0.2m.

[0010] Furthermore, the diameter of the main body of the mesh PE rigid permeable pipe is 5 to 10 cm, the thickness is 1 to 3 cm, and the diameter of the permeable holes is 1 to 5 mm.

[0011] Furthermore, the orifice sealing structure is made of clay or cement mortar, and the sealing length of the orifice sealing structure along the orifice of the horizontal drainage hole is 80cm.

[0012] Furthermore, the weight of the main body of the mesh PE rigid permeable pipe is 1 / 10 to 1 / 5 of that of a traditional concrete pipe, and the main body of the mesh PE rigid permeable pipe can be connected into different lengths through a splicing structure.

[0013] Furthermore, the splicing structure is a socket joint, a hot-melt welded joint, or a snap-fit ​​joint.

[0014] Furthermore, the main body of the mesh PE rigid permeable pipe contains UV stabilizers and reinforcing materials, the reinforcing materials being carbon black or glass fiber.

[0015] The present invention, by adopting the above technical solution, has at least the following beneficial effects:

[0016] In this invention, the main body of the mesh PE rigid permeable pipe is made of PE material, with added UV stabilizers and reinforcing materials such as carbon black and glass fiber. PE material has strong resistance to chemicals such as acids, alkalis, and salts, making it suitable for corrosive environments such as coastal areas and saline-alkali lands, avoiding the problems of traditional galvanized steel pipes being easily corroded by soil and having a short service life. The UV stabilizers can slow down the aging rate of the pipe under direct sunlight, while the reinforcing materials increase the rigidity of the pipe, enabling it to withstand the lateral pressure of slope soil and rock, and preventing deformation or cracking. This solves the defects of traditional PVC pipes, such as weak deformation resistance and easy failure, effectively extending the service life of the device and ensuring long-term stable operation.

[0017] In this invention, the upper half of the mesh-like PE rigid permeable pipe has evenly distributed permeable holes with a diameter of 1-5mm, allowing groundwater from the slope to infiltrate efficiently into the pipe. The lower half has no permeable holes, reducing the amount of sediment entering the pipe. Simultaneously, the outer surface of the permeable pipe is wrapped with two layers of geotextile filter material, secured by ropes along the pipe's length (binding spacing ≤ 0.2m), effectively intercepting fine soil particles and preventing them from entering the pipe with groundwater and causing siltation. This design achieves high permeability while solving the problems of traditional pipes lacking effective filtration structures and being prone to clogging, ensuring long-term unobstructed drainage and guaranteeing drainage efficiency.

[0018] In this invention, a sealing structure made of clay or cement mortar is installed at the opening of the horizontal drainage hole on the slope, with a sealing length of up to 80cm. This structure is installed around the end of the main body of the mesh PE rigid permeable pipe, which can tightly seal the gap between the opening and the permeable pipe, preventing surface water carrying sediment from flowing back into the pipe. This avoids both the aggravation of siltation inside the pipe and the reduction of surface water erosion of the slope soil and rock, solving the problem of "secondary damage" caused by the inadequate sealing of the opening in traditional devices, and further ensuring the stability of the slope.

[0019] In this invention, the main body of the mesh PE rigid permeable pipe weighs only 1 / 10 to 1 / 5 of that of a traditional concrete pipe. It can be manually transported and installed without the need for large construction machinery, making it particularly suitable for narrow working surfaces on slopes and reducing construction intensity. Furthermore, the main body of the permeable pipe can be spliced ​​into different lengths through socket joints, hot-melt welding joints, or snap-fit ​​joints, which can flexibly adapt to drainage needs with different hole depths, reducing pipe cutting waste. Compared with traditional pipes that are "heavy and rely on large equipment for construction", this invention significantly reduces construction costs and difficulty, and improves construction efficiency.

[0020] In this utility model, the PE material used in the main body of the mesh PE rigid permeable pipe is recyclable, and the entire device is free of toxic and harmful substances. Long-term use will not pollute the soil or groundwater, which meets the requirements of "green construction and environmental protection for long-term effectiveness" in slope engineering. Compared with the environmental damage that some traditional pipe materials may cause, it has greater engineering promotion value and helps green engineering construction.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a mesh PE permeable pipe device for horizontal drainage holes on slopes, including: a mesh PE rigid permeable pipe body 1, the mesh PE rigid permeable pipe body being adapted to the hole diameter of the horizontal drainage holes on the slope, the upper half of the mesh PE rigid permeable pipe body having permeable holes evenly distributed around its circumference, and the lower half of the mesh PE rigid permeable pipe body having no permeable holes.

[0027] A filter layer, which is wrapped around the outer periphery of the mesh PE rigid permeable pipe body, is used to intercept fine soil particles;

[0028] The orifice sealing structure 4 is installed at the orifice of the horizontal drainage hole on the slope, and the orifice sealing structure is arranged around the end of the mesh PE rigid permeable pipe body to seal the gap between the orifice of the horizontal drainage hole and the mesh PE rigid permeable pipe body.

[0029] In one implementation, the filter layer in this embodiment is geotextile 2, and the geotextile has two layers. The two layers of geotextile are fixed along the length of the main body of the mesh PE rigid permeable pipe by binding members. This ensures that the filter layer is tightly attached to the main body of the permeable pipe, preventing the filter layer from shifting and causing filtration failure.

[0030] In one implementation method, the geotextile in this embodiment is a spunbond geotextile, and the binding element is a rope, with the binding spacing of the rope along the length of the main body of the mesh PE rigid permeable pipe not exceeding 0.2m. The spunbond geotextile possesses excellent filtration performance and permeability, effectively intercepting fine soil particles while ensuring groundwater can smoothly pass through the filter layer into the main body of the permeable pipe. Using rope as the binding element and controlling the binding spacing to ≤0.2m ensures that the two layers of geotextile always tightly wrap around the outer circumference of the permeable pipe body, preventing the geotextile from loosening or falling off due to external pulling during construction, thus ensuring the continuous and stable operation of the filtration function.

[0031] In one embodiment, the diameter of the main body 1 of the mesh PE rigid permeable pipe is 5 to 10 cm, the thickness is 1 to 3 cm, and the diameter of the permeable holes is 1 to 5 mm. This size design is suitable for the conventional borehole diameter 3 of the horizontal drainage hole on the slope (such as a Φ110 mm borehole), which can avoid the gap between the permeable pipe body and the hole wall being too large or too small, affecting installation and drainage; the pipe thickness of 1 to 3 cm can ensure that the permeable pipe body has sufficient structural rigidity to resist the lateral pressure of the slope rock and soil and prevent pipe deformation; the permeable hole diameter of 1 to 5 mm can achieve efficient infiltration of groundwater while initially blocking some coarse soil particles, reducing impurities entering the pipe body and reducing the burden on the subsequent filtration layer.

[0032] In one implementation method, the orifice sealing structure in this embodiment is made of clay or cement mortar, and the sealing length of the orifice sealing structure along the orifice opening of the horizontal drainage hole is 80cm. Clay and cement mortar are readily available materials with strong sealing properties, effectively filling the gap between the orifice opening and the main body of the permeable pipe; the 80cm sealing length ensures that a sealing barrier is formed from the outside of the orifice to a certain depth inside the hole, completely blocking the path of surface water carrying sediment backflow into the main body of the permeable pipe, thus avoiding both increased siltation inside the pipe and preventing surface water from eroding the slope soil and rock, ensuring the stability of the slope structure.

[0033] As one implementation method, the weight of the main body of the mesh PE rigid permeable pipe in this embodiment is 1 / 10 to 1 / 5 of the weight of a traditional concrete pipe, and the main body of the mesh PE rigid permeable pipe can be connected into different lengths through a splicing structure. The lightweight characteristics of the permeable pipe body (only 1 / 10 to 1 / 5 the weight of a traditional concrete pipe) eliminate the need for large construction machinery, and manual handling and installation can be completed, making it particularly suitable for operation scenarios with narrow slopes and where large equipment is difficult to access; by adjusting the pipe length through the splicing structure, it can flexibly adapt to horizontal drainage holes of different slope depths, avoiding cutting waste caused by fixed pipe length and improving the adaptability of the device to different engineering scenarios.

[0034] As one implementation method, the splicing structure described in this embodiment is a socket joint, a thermofusion welded joint, or a snap-fit ​​joint. Socket joints are easy to install and can quickly complete pipe splicing, making them suitable for projects with tight schedules. The thermofusion welded joint allows two pipe sections to form a single unit, providing excellent sealing and preventing leakage or sand ingress at the joint, making it suitable for scenarios with high sealing requirements. Snap-fit ​​joints are detachable, allowing for flexible disassembly and replacement of pipe sections during later maintenance. The three joint types can be selected according to the actual needs of the project, all ensuring the structural stability and unobstructed drainage of the pipe after splicing.

[0035] As one implementation method, the main body of the mesh PE rigid permeable pipe in this embodiment contains an anti-ultraviolet agent and reinforcing materials, wherein the reinforcing materials are carbon black or glass fiber. The anti-ultraviolet agent can slow down the aging rate of the permeable pipe body under direct sunlight outdoors, extending the service life of the device; carbon black or glass fiber, as reinforcing materials, can significantly improve the structural rigidity and impact resistance of the pipe body, making the permeable pipe body less prone to deformation and flattening when deeply buried or subjected to large slope pressure, ensuring stable long-term drainage function.

[0036] This embodiment optimizes the material selection, parameter design, and connection methods of each component of the mesh PE permeable pipe device for horizontal drainage holes on slopes, forming a complete and practical technical solution. The core is a mesh PE rigid permeable pipe, complemented by two layers of long-filament spun clay fabric filter layers to achieve a synergistic effect of water permeability, filtration, and anti-clogging. Clay or cement mortar sealing structures at the orifices prevent backflow of surface water. The lightweight and modular design reduces construction difficulty. All implementation methods are designed around "improving drainage efficiency, extending service life, and simplifying construction processes," effectively solving the defects of traditional galvanized steel pipes (easily corroded), PVC pipes (weak deformation resistance), and traditional devices (insufficient anti-clogging). This provides a stable, efficient, and convenient horizontal drainage solution for slope engineering, helping to improve slope stability and mitigate the risks of geological disasters such as landslides and collapses.

[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
