Description

Technical Field

[0001] The utility model relates to the field of combined expansive soil slope anti-seepage and moisture-proof structures, in particular to a combined expansive soil slope anti-seepage and moisture-proof structure. Background Art

[0002] Affected by the warming and humidifying climate and extreme rainfall, the problem of expansive soil slope diseases has become increasingly prominent. Due to the lack of proper waterproofing and anti-seepage measures on the slopes, the expansive soil roadbed has suffered from sinking, squeezing, mud bubbling, erosion, landslides, and fragmentation, resulting in huge annual road maintenance costs. The original technical measures mainly included adding drainage systems, slope concrete structures, and plant protection, but the results were minimal. Under the condition of increased rainfall, the frequency of diseases caused by water infiltration into the slope has greatly increased;

[0003] However, with the influence of warming and humidification, a large number of diseases have occurred in the expansive soil area due to water infiltration, which has increased the potential safety hazards of roads and increased the labor and engineering maintenance costs. Considering that the probability of slope erosion by water has greatly increased under the condition of increased rainfall, the hydrophilic minerals in the soil layer are very likely to swell and shrink when exposed to water, causing road subsidence, uplift, external squeezing, and collapse. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a combined expansive soil slope anti-seepage and moisture-proof structure, which can solve the technical problems that the existing combined expansive soil slopes, as affected by the warming and humidification of the climate, have a large number of disease problems caused by the infiltration of water into the expansive soil area, which on the one hand increases the hidden dangers of road safety, and on the other hand increases a large amount of labor and engineering maintenance costs. In addition, considering that under the condition of increased rainwater, the probability of the slope being eroded by water is greatly increased, the hydrophilic minerals in the soil layer are very likely to swell and shrink when encountering water, resulting in technical problems such as road base body settlement, uplift, external squeezing, and collapse.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: 1. A combined expansive soil slope anti-seepage and moisture-proof structure, comprising a slope body, a slope surface is arranged on one side of the top of the slope body, an outer slope drainage ditch is opened on the upper surface of the other end of the slope body, a surface concrete slope protection layer is arranged on the side wall of the slope body, and an anti-seepage spray coating is connected to the other side of the surface concrete slope protection layer, a slope infiltration pipe is extended to the inner side of the anti-seepage spray coating, and one end of the slope infiltration pipe is a dense end of the infiltration pipe, and the end of the slope infiltration pipe away from the dense end of the infiltration pipe is a filter end of the infiltration pipe, a through cavity is opened in the inner cavity of the slope infiltration pipe, a spiral rib is arranged on the inner wall of the slope infiltration pipe, and a retaining bar is distributed on one side of the spiral rib.

[0006] As a preferred technical solution of the present utility model, the thickness of the surface concrete slope protection layer is generally ~cm, and the surface concrete slope protection layer covers the slope surface.

[0007] As a preferred technical solution of the utility model, the internal structure of the anti-seepage spray coating layer adopts nano-scale infiltration waterproof material.

[0008] As a preferred technical solution of the utility model, the slope infiltration pipes are evenly distributed along the surface of the anti-seepage spray coating, and the slope infiltration pipes are distributed in an inclined shape as a whole.

[0009] As a preferred technical solution of the utility model, the spiral ribs are distributed in a spiral shape as a whole, and the spiral ribs are symmetrically distributed on both sides of the baffle along the center point of the baffle.

[0010] As a preferred technical solution of the utility model, the baffles are equidistantly distributed along the center point of the slope internal seepage pipe, and the baffles and the slope internal seepage pipe form an integrated structure.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. The structure is simple and the construction is convenient. The surface concrete slope protection layer can effectively increase the strength and flatness of the slope. The anti-seepage spray coating can penetrate into the concrete layer and form a dense waterproof film on the surface. The seepage pipe is set inside the slope to effectively remove the moisture in the road base, ensure the stability of the slope, and appropriately reduce the expansion and deformation of the expansive soil. The structure has a short construction period, a simple construction process, and a good construction effect, which can play a role in anti-seepage and moisture-proof.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a combined expansive soil slope anti-seepage and moisture-proof structure, including a slope body 1, a slope surface 2 is arranged on one side of the top of the slope body 1, an outer slope drainage ditch 3 is opened on the upper surface of the other end of the slope body 1, a surface concrete slope protection layer 4 is arranged on the side wall of the slope body 1, and an anti-seepage spray coating 5 is connected to the other side of the surface concrete slope protection layer 4, the thickness of the surface concrete slope protection layer 4 is generally 15-30cm, and the surface concrete slope protection layer 4 covers the slope surface 2, the internal structure of the anti-seepage spray coating 5 adopts nano-level infiltration waterproof material, a slope internal seepage pipe 6 is extended inside the anti-seepage spray coating 5, and one end of the slope internal seepage pipe 6 is a dense end of the seepage pipe 7. The in-slope water seepage pipes 6 are evenly distributed along the surface of the anti-seepage spray coating 5, and the in-slope water seepage pipes 6 are distributed in an inclined shape as a whole. The end of the in-slope water seepage pipe 6 away from the dense end 7 of the water seepage pipe is the water seepage pipe filter end 8. The inner wall of the water seepage pipe filter end 8 is a mesh structure. The inner cavity of the in-slope water seepage pipe 6 is provided with a through cavity 9. The inner wall of the in-slope water seepage pipe 6 is provided with a spiral rib 10, and a baffle 11 is distributed on one side of the spiral rib 10. The spiral rib 10 is distributed in a spiral shape as a whole, and the spiral rib 10 is symmetrically distributed on both sides of the baffle 11 along the center point of the baffle 11. The baffle 11 is evenly distributed along the center point of the in-slope water seepage pipe 6, and the baffle 11 and the in-slope water seepage pipe 6 form an integrated structure;

[0021] The specific construction steps are as follows:

[0022] S1, first, use mechanical or manual methods to clean up the original slope surface 30 to 50 cm of loose soil, debris, plant roots, small pits, etc. to form a relatively flat and tidy slope surface;

[0023] S2, secondly, the surface concrete slope protection layer 4 is applied on the slope surface, and the thickness of the surface concrete slope protection layer 4 is set to 15-30cm, and the application range is the slope surface 2 from 50cm from the top of the slope, the entire slope surface to 50cm from the outside of the slope foot, and all-round coverage to ensure the overall flatness of the slope surface, and maintenance is carried out to make the strength of the concrete layer reach 75%;

[0024] S3, then construct the slope internal seepage pipe 6 on the surface concrete slope protection layer 4, and the diameter of the slope internal seepage pipe 6 is 3-5 cm, wherein the filter end 8 of the seepage pipe inserted into the slope is 50-100 cm long, and the dense end 7 of the leakage seepage pipe is 3-5 cm long, and the entire slope internal seepage pipe 6 is tilted downward by 15° to ensure smooth flow of seepage water, and the upper and lower spacing of multiple slope internal seepage pipes 6 is 1.5 m, and the left and right spacing is 2.5 m;

[0025] S4, after the infiltration pipe 6 in the slope is constructed, an anti-seepage spray coating 5 is set, and the anti-seepage spray coating 5 is inserted into the surface concrete slope protection layer 4 to a depth of 3 to 5 cm, which is consistent with the application range of the surface concrete slope protection layer 4, covering all directions to form a dense waterproof layer. After the construction is completed, it can be cured for 24 hours;

[0026] Since the inner cavity of the slope infiltration pipe 6 is provided with spiral ribs 10 and baffles 11, and the spiral ribs 10 and baffles 11 are spaced apart, when water flows inside the slope infiltration pipe 6, it flows along the spiral surface of the spiral ribs 10, thereby making the water flow spiral, and then cooperates with the diversion of multiple baffles 11, thereby reducing the generation of noise;

[0027] Through the above steps, the construction of the combined expansive soil slope anti-seepage and moisture-proof structure can be completed.
