Description

Technical Field

[0001] This utility model relates to the field of slope treatment technology, specifically to a combined slope drainage structure. Background Technology

[0002] Groundwater is one of the key factors for slope stability. Implementing proper drainage measures for slopes is an important part of slope design, and solving the groundwater problem is crucial for slope safety and stability.

[0003] To address groundwater issues on slopes, commonly used drainage pipes are hollow plastic or steel perforated pipes. Plastic pipes suffer from insufficient durability, are prone to aging, and the outlet holes are easily clogged. Hollow-walled pipes lack structural support, making them susceptible to breakage and filling with soil, leading to reduced permeability or even failure. Currently, hollow drainage pipes of various materials are ineffective in reinforcing slopes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention aims to provide a combined slope drainage structure. This solution achieves drainage while simultaneously reinforcing the slope.

[0005] This utility model is achieved through the following technical solution:

[0006] A combined slope drainage structure, comprising:

[0007] The pipe has several through holes in its sidewalls; the inside of the pipe is filled with densely packed filter sand and gravel.

[0008] A permeable cloth is provided, which is arranged circumferentially along the inner diameter of the pipe and wraps the filter sand and gravel inside the pipe.

[0009] The pipe is used to insert into the slope, and the end of the pipe inserted into the slope is inclined upwards.

[0010] In contrast to existing technologies where hollow drainage pipes of various materials fail to reinforce slopes, this invention provides a combined slope drainage structure. This solution achieves drainage while simultaneously reinforcing the slope. Specifically, the structure includes a cylindrical pipe with several through-holes on its sidewalls to allow groundwater to enter. The pipe is filled with densely packed filter sand, which is then wrapped with permeable fabric. This dense fill of filter sand provides structural support, preventing damage from external pressure and supporting the surrounding soil and rock mass. Groundwater permeates through the through-holes and permeable fabric into the filter sand, then flows out through the inclined pipe towards the outside of the slope, achieving drainage. This utility model designs a combined slope drainage structure that forms an open and stable seepage channel by filling the internal pipes with dense filter sand and gravel, eliminating the problem of blockage and reinforcing the slope. It also drains groundwater through permeable fabric and inclined pipes, effectively managing both deep and shallow groundwater levels and reducing slope instability caused by groundwater. This structure can be implemented simultaneously during the slope design and construction phases, and can also be used for targeted treatment of slopes already affected by groundwater.

[0011] To further optimize the design and facilitate construction by creating a dense network of water inlet channels, the pipe is constructed by welding galvanized steel wire mesh together. In this solution, if a steel pipe drainage system were used, additional through-holes would need to be fabricated within the pipe, and the internal permeable fabric and filter sand would be difficult to install. Therefore, this solution replaces the pipe with galvanized steel wire mesh, which is then welded together to form the pipe shape. Before welding, the dense filter sand can be wrapped with permeable fabric, and then the galvanized steel wire mesh can be wrapped around the permeable fabric and welded. This structure is easy to construct, and the galvanized steel wire mesh itself has a dense network of channels, making it less prone to clogging. Both ends of the pipe are also sealed with galvanized steel wire mesh.

[0012] To further optimize the pipeline and enhance its structural strength, forming a supporting framework, steel bars are welded to the inner side of the pipeline, with these bars arranged along the length of the pipeline. Several steel bars are also evenly distributed circumferentially along the inner side of the pipeline. These steel bars are welded to the inner wall of the pipeline and arranged along its length to reinforce the pipeline, forming a support framework that prevents pipeline deformation and reinforces the slope.

[0013] To further optimize the process, the pipe is reinforced sequentially along its length by being tied with several galvanized steel wires at intervals along its length.

[0014] Furthermore, the galvanized steel wire is bundled along the circumferential direction of the pipe.

[0015] To further optimize the structure and prevent rusting, which would reduce structural strength, both the pipes and the reinforcing bars are coated with anti-rust paint.

[0016] As a redundancy solution, the permeable fabric is made of nylon gauze.

[0017] As a redundancy solution, the filter sand is medium to coarse sand.

[0018] As a redundancy solution, the pipe is at a 15° angle to the horizontal direction.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0020] 1. The combined slope drainage structure designed in this utility model can form an open and stable seepage channel by filling the internal pipes with dense filter sand and gravel, eliminating the problem of blockage and reinforcing the slope. Furthermore, it effectively drains groundwater through permeable fabric and inclined pipes, thereby reducing slope instability caused by groundwater. This structure can be implemented simultaneously during the slope design and construction phases, and can also be used for targeted treatment of slopes already affected by groundwater.

[0021] 2. This utility model designs a combined slope drainage structure by replacing the pipes with galvanized steel wire mesh, which is then welded together to form the pipe shape. Before welding, a permeable cloth can be used to wrap dense filter sand and gravel, and then the galvanized steel wire mesh can be wrapped around the permeable cloth and welded. This structure is easy to construct, and the galvanized steel wire mesh itself has dense channels, making it less prone to clogging. Reinforcing bars are welded to the inside of the pipe and installed along its length to reinforce it, forming a supporting framework that prevents pipe deformation and strengthens the slope.

[0031] Example 1:

[0032] This embodiment 1 provides a combined slope drainage structure, such as Figures 1-3 As shown, it includes:

[0033] Pipe 7, the side wall of which has several through holes; the inside of pipe 7 is filled with densely packed filter sand and gravel 3;

[0034] Permeable cloth 2, the permeable cloth 2 is arranged circumferentially along the inner diameter of the pipe 7, and wraps the filter sand 3 inside the pipe 7;

[0035] The pipe 7 is used to be inserted into the slope 6, and the end of the pipe 7 inserted into the slope 6 is inclined upward.

[0036] In contrast to existing technologies where hollow drainage pipes of various materials fail to reinforce slope 6, this invention provides a combined slope 6 drainage structure. This solution achieves drainage while simultaneously reinforcing the slope 6. Specifically, the structure includes a pipe 7, a cylindrical structure with several through-holes on its sidewalls to allow groundwater to enter. The pipe 7 is filled with densely packed filter sand 3, which is then wrapped with permeable cloth 2. This densely packed filter sand 3 provides structural support for the pipe 7, preventing damage from external pressure and supporting the surrounding soil and rock mass. Groundwater permeates through the through-holes and permeable cloth 2 into the filter sand 3, then flows out through the inclined pipe 7 to the outside of the slope 6, achieving drainage. The combined slope drainage structure designed in this utility model can form an open and stable seepage channel by filling the internally with dense filter sand and gravel 3 to support the pipe 7, eliminating the problem of blockage and reinforcing the slope 6. Furthermore, it effectively drains groundwater through the permeable fabric 2 and the inclined pipe 7, thereby reducing the instability of the slope 6 caused by groundwater. This structure can be implemented simultaneously during the design and construction phases of the slope 6, and can also be used for targeted treatment of slopes 6 already affected by groundwater.

[0037] Example 2:

[0038] This embodiment 2 is a further optimization based on embodiment 1, providing a specific structure for pipe formation.

[0039] In this embodiment, to facilitate construction and create a dense water inlet channel, the pipe 7 is constructed by welding together galvanized steel wire mesh (5 meshes). If a steel pipe drainage pipe or similar structure were used, additional through holes would need to be fabricated on the pipe body, and the internal permeable cloth (2) and filter sand (3) would be difficult to install. Therefore, this solution replaces the pipe 7 with galvanized steel wire mesh (5 meshes), which are then welded together to form the pipe 7 shape. Before welding, the permeable cloth (2) can be used to wrap the dense filter sand (3), and then the galvanized steel wire mesh can be wrapped around the permeable cloth (2) and welded together. This structure is easy to construct, and the galvanized steel wire mesh itself has a dense network of channels, making it less prone to clogging. Both ends of the pipe 7 are also sealed with galvanized steel wire mesh (5 mesh).

[0040] In some embodiments, to enhance the structural strength of the pipe 7 and form a supporting frame, reinforcing bars 4 are welded to the inner side of the pipe 7, and the reinforcing bars 4 are arranged along the length of the pipe 7; a plurality of the reinforcing bars 4 are evenly distributed circumferentially along the inner side of the pipe 7. The reinforcing bars 4 are welded to the inner wall of the pipe 7 and arranged along the length of the pipe 7 to reinforce the pipe 7, forming a supporting frame as a whole. This prevents deformation of the pipe 7 and also reinforces the slope 6.

[0041] In some embodiments, to reinforce the pipe 7 sequentially along its length, the pipe 7 is sequentially and spaced apart with several galvanized steel wires 5.

[0042] In some embodiments, the galvanized steel wire 5 is bundled along the circumferential direction of the pipe 7.

[0043] In some embodiments, to prevent rusting and thus reduce structural strength, both the pipe 7 and the reinforcing bar 4 are coated with anti-rust paint.

[0044] In some embodiments, the permeable fabric 2 is made of nylon gauze.

[0045] In some embodiments, the filter sand 3 is medium-coarse sand.

[0046] In some embodiments, the pipe 7 is at a 15° angle to the horizontal direction.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
