Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a drainage and exhaust device with a simple anti-seepage structure. Background Art

[0002] In the existing reservoir water storage area, the geotextile membrane + drainage net anti-seepage form is adopted, and the geotextile membrane + bentonite pad anti-seepage form is adopted for the slope. This anti-seepage form has little impact on the surrounding environment, is convenient and flexible in construction, and has low material permeability. It is widely used in solid storage yards and liquid reservoirs. Under the influence of various factors, a part of the converging water is discharged through the intercepting and drainage system arranged around, and another part of the converging water directly infiltrates into the loose soil to form groundwater, and finally flows into the low-lying area downstream of the reservoir area. Some of the infiltrated water flows under the membrane, and when the temperature rises, an air current is formed, resulting in the risk of local geotextile membrane floating. Under the action of the upper pressure, the local folds of the geotextile membrane constantly change to produce a bulging phenomenon. Therefore, a drainage and exhaust device with a simple anti-seepage structure is proposed here. In the case of complex terrain, it can more effectively and simply solve the problem of gas expansion caused by gas disorder under the anti-seepage structure, improve the exhaust efficiency under the anti-seepage structure, control the water level under the anti-seepage structure, increase the service life of the anti-seepage structure, and reduce the leakage hidden danger caused by the damage of the anti-seepage structure.

When laying the anti-seepage structure, a hole is reserved at the reservoir top. The elbow passes through and is extrusion-welded with the anti-seepage structure. The remaining anti-seepage structure is unfolded in place at one time, and the folding and wrinkles of the anti-seepage structure beside the pipeline are smoothed. When necessary, a dimensional expansion amount caused by the thermal expansion and contraction of the anti-seepage material is reserved.

[0006] Preferably: The elbow, inclined pipe, horizontal pipe and vertical pipe are connected as a whole. The vertical pipe has an opening extending into the collection ditch.

[0014] In the embodiment of the present application, by providing a drainage and exhaust device with a simple anti-seepage structure, it effectively solves the technical problem that in the existing reservoir water storage area, the geotextile membrane + drainage net anti-seepage form is adopted. Part of the collected water is discharged through the intercepting and drainage system set around, and the other part of the collected water directly seeps into the loose soil to form groundwater, and finally flows into the low-lying area downstream of the reservoir area. Part of the seepage water flows under the membrane, and when the temperature rises, it forms an air flow, resulting in the risk of local geotextile membrane floating, and under the action of the upper pressure, the local folds of the geotextile membrane change continuously to produce the air bulge phenomenon.

[0015] Embodiment

[0016] The general idea of the technical solution in the embodiment of the present application is as follows:

[0017] As Figure 1-2As shown in the figure, in view of the problems existing in the prior art, the utility model provides a drainage and exhaust device with a simple anti-seepage structure, which includes an elbow 1, a non-perforated inclined pipe 2, a perforated inclined pipe 3, an anti-seepage structure 4, a sleeve 5, a clamp 6, a horizontal pipe 7, a vertical pipe 8, a filter layer 9, a protective layer 10, a collection ditch 11, a collection water pipe 12, and a slope 13. The pipeline is arranged at the bottom of the anti-seepage structure 4. The non-perforated inclined pipe 2 and the perforated inclined pipe 3 are arranged along the slope 13. When laying the anti-seepage structure 4, a hole is reserved at the top of the slope. The elbow 1 passes through and is extrusion-welded with the anti-seepage structure 4. The remaining anti-seepage structure 4 is unfolded in place at one time, and the folds and wrinkles of the anti-seepage structure 4 beside the pipeline are smoothed. If necessary, a dimensional expansion and contraction amount caused by the thermal expansion and contraction of the anti-seepage material 4 is reserved;

[0018] The elbow 1, the perforated inclined pipe 3, the anti-seepage structure 4, the horizontal pipe 7, and the vertical pipe 8 are connected into a whole. The vertical pipe 8 has holes extending into the collection ditch 11. After the pipeline is fixed, the protective layer 10 is spread. The material and thickness are selected according to the soil conditions. A collection water pipe 12 is reserved in the ditch, and the filter layer 9 is spread and filled into the trench;

[0019] The vertical pipe 8 is connected to the collection water pipe 12. When the water level under the anti-seepage structure 4 is relatively low, exhaust can be carried out. When the water level under the anti-seepage structure 4 is relatively high, a water pump is inserted into the pipeline to pump out the groundwater under the anti-seepage structure 4;

[0020] The elbow 1, the non-perforated inclined pipe 2, and the perforated inclined pipe 3 can be made of HDPE material and welded by hot melting. The connection between the pipeline and the anti-seepage structure 4 is made by extrusion welding, and the strength and airtightness of the weld are detected;

[0021] The elbow 1 passes through the anti-seepage structure 4, and the weld between the elbow 1 and the anti-seepage structure 4 is strengthened and fixed by a sleeve 5 and a clamp 6. The sleeve 5 can be made of HDPE material, and the clamp 6 can be made of stainless steel material. The pipeline passing through the anti-seepage structure 4 adopts a U-shaped bend, and the air outlet end is parallel to the slope 13, which can effectively prevent water and sundries from entering;

[0022] The slope 13 is sloped at a ratio of 1:2 - 1:5. The non-perforated inclined pipe 2 and the perforated inclined pipe 3 are parallel to the slope 13. The pipeline is extrusion-welded with the anti-seepage structure 4, playing a role in fixing and preventing slipping and sealing;

[0023] The pipeline structure is connected into a whole by the elbow 1, the non-perforated inclined pipe 2, the perforated inclined pipe 3, the horizontal pipe 7, and the vertical pipe 8. The opening positions of the pipeline are arranged at intervals. The included angle of the openings of the perforated pipelines in the same cross-section is 60 degrees. The bottom is not perforated. The vertical spacing of the openings is 110 - 150 mm, and the opening size is 10 - 15 mm. The diameter of the pipeline in the slope 13 section can be determined by the water level. The diameter of the collection water pipe 12 in the collection ditch 11 is larger than that of the pipeline in the slope 13 section;

[0024] The non-perforated inclined pipe 2, the perforated inclined pipe 3, the horizontal pipe 7 and the vertical pipe 8 are hot melt welded, and the vertical pipe 8 extends into the collection ditch 11 to guide and discharge the gas under the pipe body opening drainage and anti-seepage structure 4. A collection water pipe 12, a filter layer 9 and a protective layer 10 are arranged in the collection ditch 11. The filter material can be pebbles, crushed stones and gravels, the particle size of the stones is 10-60 mm, and the calcium carbonate content in the stones is not more than 5%, so as to prevent the filter layer 9 and the protective layer 10 in the collection ditch 11 from caking due to calcification over time, resulting in a reduction in the drainage and exhaust effects.

[0025] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
