[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0026] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0027] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0028] In order to solve the problem of liquid seepage on the ground of the wine lees storage site, this embodiment provides a wine lees storage site ground anti-seepage structure, referring to Figure 1 , including a top layer 1, a sand cushion layer 2, an anti-seepage layer 3, and a bottom layer 4 stacked in sequence from top to bottom; the stacked wine lees are located on the top layer 1, which is a structural panel on the ground. Once cracked, the wine lees will leak into the ground, which is easy to pollute the environment; therefore, for environmental protection and to reduce the cost of preventing environmental pollution, the anti-seepage layer 3 includes a first waterproof roll material layer 3a, a waterproof coating layer 3b, and a second waterproof roll material layer 3c stacked in sequence from top to bottom; the first waterproof roll material layer 3a is connected to the sand cushion layer 2, and the second waterproof roll material layer 3c is connected to the bottom layer 4. The anti-seepage layer 3 is a flexible anti-seepage layer 3, and the waterproof coating layer 3b in this structure is prepared from a non-curing rubber asphalt waterproof coating, which solves the problems of fracture, flexural fatigue, or premature aging under high stress caused by the cracking stress of the top layer 1 being transferred to the anti-seepage layer 3; at the same time, the viscosity of the creep material enables it to well seal pores and cracks, solves the problem of water leakage in the anti-seepage layer 3, and greatly improves the waterproof reliability. The anti-seepage layer 3 has the characteristics of good flexibility, strong sealing, high anti-seepage performance, etc., which can effectively prevent the leakage of the waste liquid.

[0029] In the specific implementation process, a first non-woven fabric layer 5 is provided between the sand cushion layer 2 and the anti-seepage layer 3; a second non-woven fabric layer 6 is provided between the anti-seepage layer 3 and the bottom layer 4, that is, the first non-woven fabric layer 5 and the second non-woven fabric layer 6 are provided on the upper and lower parts of the anti-seepage layer 3, which, on the one hand, play a role in protecting the anti-seepage layer 3, and on the other hand, the first non-woven fabric and the sand cushion layer 2, and the second non-woven fabric and the bottom layer 4 can slide against each other, thereby avoiding the transfer of temperature internal force to the anti-seepage layer 3 when the bottom layer 4 and the top layer 1 expand and contract due to heat, thereby achieving relatively free thermal expansion and contraction of the anti-seepage layer 3 and effectively avoiding cracking of the anti-seepage layer 3; and the first sliding layer 7 and the second sliding layer 8 are respectively used to make the first non-woven fabric layer 5 and the sand cushion layer 2, and the second non-woven fabric layer 6 and the bottom layer 4 slide against each other. More specifically, the first sliding layer 7 and the second sliding layer 8 are both plastic films to reduce the friction between adjacent layers and improve their sliding effect.

[0030] More specifically, an antibacterial layer 9 is provided between the sand cushion layer 2 and the top layer 1, and the antibacterial layer 9 can effectively prevent the growth and reproduction of mold on the anti-seepage layer 3, thereby improving the service life of the anti-seepage layer 3 and reducing the probability of mold on the overall structure; and the antibacterial layer 9 is provided at the lower part of the top layer 1 to prevent the antibacterial layer 9 from being damaged, thereby enhancing the durability of the antibacterial layer 9 and the anti-seepage layer 3.

[0031] A water-absorbing layer 10 is provided between the first non-woven fabric layer 5 and the anti-seepage layer 3; the water-absorbing layer 10 is a material selected from the group consisting of a highly absorbent resin material and a high-density sponge; the water-absorbing layer 10 can absorb water that penetrates into the anti-seepage layer 3, thereby reducing the amount of water that penetrates into the anti-seepage layer 3, improving the service life of the anti-seepage layer 3 to a certain extent, and thereby effectively preventing leakage of the tank liquid.

[0032] This is achieved in this embodiment:

[0033] 1. Laying the second sliding layer 8 and the second non-woven fabric layer 6 on the hardened structural bottom plate (i.e., the bottom layer 4) in sequence, so that the second non-woven fabric layer 6 and the bottom layer 4 can slide against each other;

[0034] 2. Laying the second waterproof roll material layer 3c and the waterproof coating layer 3b on the second non-woven fabric layer 6 in sequence, so that the second waterproof roll material layer 3c is closely attached to the waterproof coating layer 3b, and then laying the first waterproof roll material layer 3a on the waterproof coating layer 3b, so that the two layers of waterproof roll material and the waterproof coating layer 3b constitute a waterproof core layer;

[0035] 3. Lay a water-absorbing layer 10, a first non-woven fabric layer 5, a first sliding layer 7, the sand cushion layer 2, and the antibacterial layer 9 on the first waterproof membrane layer 3a, wherein the sand cushion layer 2 and the first non-woven fabric layer 5 can slide against each other, and finally cast the top layer 1 (i.e., cast the structural panel) on the sand cushion layer 2.

[0036] Compared with the conventional landfill anti-seepage design method, this embodiment has a simple anti-seepage structure process, no complicated requirements and methods, easy to control construction quality, and relatively economical cost, and is suitable for promotion.

[0037] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
