Description
A large-area distillery waste storage yard ground seepage prevention expansion joint structure Technical Field
[0001] This utility model relates to the field of waterproofing technology, specifically to a seepage-proof expansion joint structure for a large-area wine lees storage yard. Background Technology
[0002] In projects utilizing distiller's grains as resources, distiller's grains storage areas are indispensable. Because distiller's grains contain a large amount of undecomposed organic matter and elements such as nitrogen, phosphorus, and potassium, if these undecomposed organic matter seeps into the soil, it can lead to excessive proliferation of soil microorganisms, consuming oxygen and producing organic acids that cause soil acidification. Meanwhile, nitrogen, phosphorus, and potassium can pollute groundwater or cause eutrophication of water bodies. Therefore, the seepage prevention requirements of distiller's grains must be considered in the structural design of soil-based distiller's grains storage areas.
[0003] For large-area distiller's grains storage areas, expansion joints are required on the ground, where leakage of distiller's grains is likely to occur. Therefore, this application provides a seepage-proof expansion joint structure for large-area distiller's grains storage areas to meet the seepage prevention requirements at these expansion joints.

[0025] Referring to Figure 1, this application embodiment provides a large-area distillery waste storage yard ground seepage prevention expansion joint structure, which includes a first construction base plate 1 and a second construction base plate 2 arranged horizontally at intervals. The bottom side of the first construction base plate 1 near the second construction base plate 2 is provided with a first extension plate 11 extending towards the second construction base plate 2. The first extension plate 11 is spaced apart from the second construction base plate 2. The top side of the second construction base plate 2 near the first construction base plate 1 is provided with a second extension plate 21 extending towards the first construction base plate 1. The second extension plate 21 is spaced apart from the first construction base plate 1. The second extension plate 21 is located above the first extension plate 11 and spaced apart from the first extension plate 11. The gap between the first extension plate 11 and the second construction base plate 2, the gap between the first extension plate 11 and the second extension plate 21, and the gap between the second extension plate 21 and the first construction base plate 1 form an expansion joint.
[0026] Referring to Figure 1, specifically, the bottom and top surfaces of the first-constructed base plate 1 and the subsequent-constructed base plate 2 are flush. The bottom surface of the first extension plate 11 is integrally cast with the first-constructed base plate 1 and is flush with it. The top surface of the second extension plate 21 is integrally cast with the subsequent-constructed base plate 2 and is flush with it. The thickness of the first extension plate 11 is no more than half the thickness of the first-constructed base plate 1, and the thickness of the second extension plate 21 is no more than half the thickness of the subsequent-constructed base plate 2, so that a gap is formed between the first extension plate 11 and the second extension plate 21, thereby forming an expansion joint. The formed expansion joint is Z-shaped, and the width of the expansion joint is set as needed.
[0027] Referring to Figure 1, further, an elastic waterproofing strip 3 is provided between the rear construction base plate 2 and the first extension plate 11. The elastic waterproofing strip 3 is attached to the bottom surface of the rear construction base plate 2 and the bottom surface of the first extension plate 11 and covers the gap between the bottom surface of the rear construction base plate 2 and the bottom surface of the first extension plate 11. The elastic waterproofing strip 3 is connected to a first waterproofing strip 31 and a second waterproofing strip 32 arranged along the length direction of the expansion joint. The first waterproofing strip 31 is embedded in the first extension part, and the second waterproofing strip 32 is embedded in the rear construction base plate 2.
[0028] Referring to Figure 1, when the first waterproof strip 31 is embedded in the first extension and the second waterproof strip 32 is embedded in the subsequent construction base slab 2, the expansion joint is separated from the underground soil by the elastic waterproof strip 3, the first waterproof strip 31, and the second waterproof strip 32, thereby achieving water-proofing and seepage prevention. Specifically, grooves are provided on the bottom surface of the subsequent construction base slab 2 and the bottom surface of the first extension plate 11 for the elastic waterproof strip 3 to be embedded, so that the bottom surface of the elastic waterproof strip 3 is flush with the bottom surface of the subsequent construction base slab 2. The elastic waterproof strip 3, the first waterproof strip 31, and the second waterproof strip 32 are integrally formed, and the material can be a high-polymer elastic waterproof material such as rubber. Multiple first waterproof strips 31 and second waterproof strips 32 can be provided to improve the water-proofing effect. In this embodiment, two first waterproof strips 31 and two second waterproof strips 32 are provided for illustration.
[0029] Referring to Figure 1, furthermore, the expansion joint is filled with an elastic impermeable filling layer. Filling the expansion joint with the elastic impermeable filling layer can prevent the fermented liquid from seeping into the ground from the expansion joint, and the elastic setting of the elastic impermeable filling layer can ensure that the function of the expansion joint is not affected.
[0030] Referring to Figure 1, specifically, the elastic waterproofing layer includes a first elastic filling layer 4, which fills the gap between the subsequent construction base plate 2 and the first extension plate 11 and extends to the bottom surface of the second extension plate 21. The first elastic filling layer 4 serves as a waterproofing structure before the elastic waterproofing tape 3, reducing the permeability gaps between the first extension plate 11 and the subsequent construction base plate 2 while ensuring the function of the expansion joint. The elastic waterproofing layer can be formed by inserting closed-cell polyethylene foam board or fiberboard into the gap between the subsequent construction base plate 2 and the first extension plate 11.
[0031] Referring to Figure 1, an elastic water-stop plate 5 is further provided between the first extension plate 11 and the second extension plate 21. The elastic water-stop plate 5 is arranged along the length of the expansion joint and is embedded in the first extension plate 11 and the second extension plate 21 on both sides. In the distribution direction of the first-construction base plate 1 and the subsequent-construction base plate 2, the portions of the gap between the first extension plate 11 and the second extension plate 21 located on both sides of the elastic water-stop plate 5 are not interconnected. The elastic water-stop plate 5 further separates the expansion joint to further play a role in water sealing and seepage prevention. In order to improve the water sealing effect, at least two elastic water-stop plates 5 are provided, and at least two elastic water-stop plates 5 are spaced apart in the distribution direction of the first-construction base plate 1 and the subsequent-construction base plate 2. In this embodiment, two elastic water-stop plates 5 are used for illustration. The elastic water-stop plate 5 can be made of polymer materials such as rubber or a stretchable water-stop steel strip.
[0032] Referring to Figure 1, the elastic waterproofing layer further includes a second elastic filling layer 6, which fills the gap between the first extension plate 11 and the second extension plate 21 and extends to the side of the pre-constructed base plate 1. The second elastic filling layer 6 further enhances the waterproofing performance as a waterproofing filling structure. The second elastic filling layer 6 is formed by filling the gap between the first extension plate 11 and the second extension plate 21 with an elastic waterproofing material such as rubber.
[0033] Referring to Figure 1, the gap between the second extension plate 21 and the pre-constructed base plate 1 further includes a first filling area and a second filling area distributed sequentially along the direction away from the top surface of the pre-constructed base plate 1. Specifically, the first filling area and the second filling area are distributed vertically, and the elastic seepage-proof filling layer includes an elastic water-swellable filling layer 7 filling the second filling area and an elastic sealing filling layer 8 filling the first filling area. The elastic water-swellable filling layer 7 expands upon contact with seepage water, thereby further reducing the leakage porosity between the second extension plate 21 and the pre-constructed base plate 1, serving as a seepage-proof structure before the elastic seepage-proof filling layer to enhance seepage-proof performance. The elastic sealing filling layer 8 fills the gap between the second extension plate 21 and the pre-constructed base plate 1 and forms a sealed connection, effectively preventing the seepage of fermented grains into the expansion joint as the first seepage-proof structure. The elastic water-swellable filling layer 7 can be formed by filling the second filling area with a water-swellable waterstop strip, while the elastic sealing filling layer 8 can be formed by filling the first filling area with sealant.
[0034] This application forms a multi-layered seepage-proof and water-proof structure by means of an elastic sealing filling layer 8, an elastic water-swellable filling layer 7, a second elastic filling layer 6, an elastic water-proof plate 5, a first elastic filling layer 4, and an elastic water-proof sticker 3, which can effectively prevent the fermented grain liquid from seeping into the ground through the expansion joint.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
