Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a water storage ditch suitable for pig breeding. Background Art

[0002] As pig farming continues to expand, the amount of wastewater generated is also increasing. Currently, wastewater is typically stored in underground drainage ditches installed in pig farms. To prevent water from seeping into the soil and causing soil erosion and the risk of farm building subsidence, the drainage ditches are typically cast in concrete. For example, patent document CN216038820U discloses a sewage sedimentation tank using the Biolek process, which uses an impermeable membrane and concrete to prevent wastewater in the drainage ditches from seeping into the soil. However, larger pig farms require a longer drainage ditches length. Because the drainage ditches are cast entirely in concrete, the lengthy process can lead to excessively high construction costs. Furthermore, over long periods of use, cracks may develop in certain sections of the concrete, creating leaks. This requires maintenance of the entire drainage ditches, which is also costly. Furthermore, during the concrete pouring process, the required length of concrete can be excessive, leading to cracks and leaks. This can allow wastewater to seep into the soil and cause soil erosion. Utility Model Content

[0005] The cement blanket includes geotextile and polypropylene woven cloth, concrete is arranged between the geotextile and the polypropylene woven cloth, the geotextile is arranged on the side close to the anti-seepage membrane, and the polypropylene woven cloth is arranged on the side close to the ditch body.

[0006] Furthermore, a transition slope is formed at one end of the cement blanket that is farther from the sewage source, and an angle between the transition slope and the bottom of the cement blanket is an acute angle.

[0007] Furthermore, side slopes are formed on opposite sides of the ditch body, and the angle between the side slopes and the bottom of the ditch body is an obtuse angle.

[0008] Furthermore, the obtuse angle is 120°.

[0009] Furthermore, the anti-seepage membrane is a HPDE double-sided anti-seepage membrane.

[0010] Furthermore, a fixing pier for fixing the cement blanket and the anti-seepage membrane is provided on the ditch body.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides a water storage ditch suitable for pig breeding, which is formed by overlapping a plurality of cement blankets, thereby reducing the process cost of the water storage ditch and improving the practicability of the water storage ditch.

[0019] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0020] like Figure 1-2 As shown, the embodiment of the present invention provides a water storage ditch suitable for pig farming, which is set in a pig farm, and the bottom of the water storage ditch is lower than the horizontal ground of the pig farm. The water storage ditch includes a ditch body 1, and a plurality of cement blankets 2 are arranged inside the ditch body 1. Figure 2 As shown, the arrangement and extension direction of the multiple cement blankets 2 is the same as the flow direction of the sewage in the ditch body 1, and according to the flow direction of the sewage, as shown in FIG. Figure 3 As shown, the end of one of the two adjacent cement blankets 2 that is closer to the sewage source is overlapped on top of the other cement blanket 2, and an anti-seepage membrane 3 is provided on the cement blanket 2;

[0021] The cement blanket 2 includes a geotextile 21 and a polypropylene woven fabric 22. Concrete 23 is arranged between the geotextile 21 and the polypropylene woven fabric 22. The geotextile 21 is arranged on the side close to the anti-seepage membrane 3, and the polypropylene woven fabric 22 is arranged on the side close to the ditch body 1.

[0022] During use, the anti-seepage membrane 3 provides the first layer of anti-seepage for the sewage in the ditch body 1 to prevent the sewage from penetrating into the water and soil. The geotextile 21 prevents the shape of the ditch body 1 from changing easily. The concrete 23 provides the second layer of anti-seepage for the sewage in the ditch body 1. The polypropylene woven cloth 22 provides the third layer of anti-seepage for the sewage in the ditch body 1. The three layers of anti-seepage prevent the sewage in the ditch body 1 from penetrating into the water and soil. The multiple cement blankets 2 are overlapped to prevent the sewage in the ditch body 1 from penetrating into the water and soil, avoiding the phenomenon of directly pouring concrete 23 in the ditch body 1 to cause cracks and leakage points.

[0023] In order to make the two adjacent cement blankets 2 fit better, as a preferred embodiment of the present invention, Figure 4 As shown, a transition slope 24 is formed at the end of the cement blanket 2 farther from the sewage source. The angle between the transition slope 24 and the bottom of the cement blanket 2 is an acute angle. When another cement blanket 2 is overlapped on the transition slope 24, the contact area between the two cement blankets 2 is increased, making the two cement blankets 2 fit more closely.

[0024] Side slopes 5 are formed on opposite sides of the ditch body 1. The angle between the side slopes 5 and the bottom of the ditch body 1 is an obtuse angle, and the obtuse angle is preferably 120°.

[0025] The anti-seepage membrane 3 is preferably a HPDE double-smooth anti-seepage membrane. Multiple HPDE double-smooth anti-seepage membranes are spliced ​​together by hot-melt welding. The HPDE double-smooth anti-seepage membrane has good moisture-proof and anti-permeation properties. The anti-seepage membrane 3 can also be a PVCf anti-seepage membrane.

[0026] The ditch body 1 is provided with fixing piers 4 for fixing the cement blanket 2 and the anti-seepage membrane 3, so that the cement blanket 2 and the anti-seepage membrane 3 are fixed in the ditch body 1 and will not move due to long-term use.

[0027] In summary, the water storage ditch suitable for pig farming is formed by overlapping multiple cement blankets 2, which reduces the process cost of the water storage ditch and thus improves the practicality of the water storage ditch.

[0028] The above-described embodiments merely represent implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
