Description

Technical Field

[0001] The present invention relates to the technical field of rural infrastructure reconstruction, and in particular to an anti-floating underground tank structure and a use method thereof. Background Art

[0002] During the construction of rural infrastructure renovation projects, the common integrated septic tank is installed and arranged directly underground. The fiberglass tank installed directly underground is usually cylindrical and placed horizontally. Figure 1 As shown, the underground tank structure of the septic tank includes a tank shell 1. When the tank shell 1 is buried underground, it will be difficult to fix when the groundwater level is high and the depth of the covering soil is shallow. At the same time, due to the development of ecological agriculture, residents often use the fertilizer water in the tank, causing the installed tank to float up and become unhooked under the action of groundwater. Figure 1 In the process, under the action of groundwater buoyancy, the tank shell 1 rises, causing the ground A directly above the tank shell 1 to bulge upward, forming a ground bulge A1. The rising of the tank shell 1 will cause damage to the connecting pipes and even the tank itself. Summary of the Invention

[0003] In order to solve the above problems in the prior art, the present invention provides an anti-floating underground tank structure.

[0004] On the one hand, the present invention provides an anti-floating underground tank structure, which adopts the following technical solutions: An anti-floating underground tank structure includes a tank shell and an internal soft layer located inside the tank shell. The internal soft layer is fixed to the inner wall of the tank shell and divides the interior of the tank shell into an upper storage area and a lower water storage buffer area. A reserved water seepage port is provided on the outer wall of the tank shell and is connected to the water storage buffer area.

[0005] Optionally, a first partition plate and a second partition plate are fixed in the tank shell, and the first partition plate and the second partition plate divide the interior of the tank shell into a first chamber, a second chamber and a third chamber, and the built-in soft layers in the first chamber, the second chamber and the third chamber are separately formed into a whole.

[0006] Optionally, a water inlet is fixed at one end of the outer wall of the tank shell, and a water outlet is fixed at the other end of the outer wall of the tank shell, the water inlet is connected to the first chamber, and the water outlet is connected to the second chamber, a first connecting pipe is fixed on the first partition plate, and the fertilizer water in the first chamber can enter the second chamber through the first connecting pipe, and a second connecting pipe is fixed on the second partition plate, and the fertilizer water in the second chamber can enter the third chamber through the second connecting pipe.

[0007] On the other hand, the present invention also discloses a method for using an anti-floating underground tank structure, comprising the following steps: S1. When the groundwater level rises, the groundwater enters the water storage buffer zone between the tank shell and the built-in soft layer through the reserved seepage port of the tank shell, and the buoyancy directly acts on the built-in soft layer; S2. When the groundwater level drops, the groundwater returns to the soil through the reserved seepage holes in the tank shell. At the same time, the built-in soft layer returns to its original position under the gravity of the fertilizer water in the tank shell.

[0008] Compared with the prior art, the present invention has the following technical effects: When the groundwater level rises, the groundwater enters the water storage buffer zone between the tank shell and the built-in soft layer through the reserved seepage port of the tank shell. The buoyancy acts directly on the built-in soft layer, which can effectively avoid the rise and fall of the underground tank due to the rise and fall of the groundwater level and improve the service life of tanks such as underground integrated septic tanks.

[0011] The following is combined with Figure 2 -Attached Figure 4 The present invention is described in further detail.

[0012] Reference Figure 2-Figure 4The present invention discloses an anti-floating underground tank structure, comprising a tank shell 1 and a first partition plate 11 and a second partition plate 12 located within the tank shell 1. Both the first partition plate 11 and the second partition plate 12 are secured to the inner wall of the tank shell 1 and divide the interior of the tank shell 1 into a first chamber 13, a second chamber 14, and a third chamber 15. In the figure, A represents the ground surface; B represents the groundwater level; C represents the water level within the tank; and F represents the groundwater buoyancy.

[0013] A first inspection well 16 and a second inspection well 17 are fixed to the top of the tank shell 1. The first inspection well 16 is located above the first chamber 13, and the second inspection well 17 is located above the second chamber 14. A water inlet 18 is fixed to one end of the outer wall of the tank shell 1, and a water outlet 19 is fixed to the other end of the outer wall of the tank shell 1. The water inlet 18 is connected to the first chamber 13, and the water outlet 19 is connected to the second chamber 14. A first connecting pipe 2 is fixed to the first partition plate 11, and the fertilizer water in the first chamber 13 can enter the second chamber 14 through the first connecting pipe 2. A second connecting pipe 3 is fixed to the second partition plate 12, and the fertilizer water in the second chamber 14 can enter the third chamber 15 through the second connecting pipe 3.

[0014] The first chamber 13, the second chamber 14, and the third chamber 15 are each provided with a built-in soft layer 4. The built-in soft layer 4 in the first chamber 13, the second chamber 14, and the third chamber 15 is formed into a single entity. The built-in soft layer 4 is made of rubber. The built-in soft layer 4 divides the first chamber 13, the second chamber 14, and the third chamber 15 into two upper and lower areas. The upper area is a storage area for storing fertilizer water, and the lower area is a water buffer area for storing groundwater. When the groundwater level is low, the built-in soft layer 4 clings to the inner wall of the tank shell 1 under the action of the gravity of the fertilizer water, and the water buffer area does not exist.

[0015] The built-in soft layer 4 in the first chamber 13 is fixed to the inner wall of the tank shell 1, and the side of the built-in soft layer 4 close to the first partition plate 11 is fixed to the first partition plate 11; the built-in soft layer 4 in the second chamber 14 is fixed to the inner wall of the tank shell 1, and the side of the built-in soft layer 4 in the second chamber 14 close to the first partition plate 11 is fixed to the first partition plate 11, and the side close to the second partition plate 12 is fixed to the second partition plate 12; the built-in soft layer 4 in the third chamber 15 is fixed to the tank shell 1, and the side close to the second partition plate 12 is fixed to the second partition plate 12. A plurality of reserved seepage openings 6 are provided on the outer wall of the tank shell 1, and groundwater can enter the water storage area in the tank shell 1 through the reserved seepage openings 6. A concrete cushion layer 5 is fixed under the tank shell 1.

[0016] When the groundwater level is low and the internal soft layer 4 is not affected by the groundwater's buoyancy, the sewage or fertilizer water within the tank shell 1 clings to the inner wall of the tank shell 1 due to its gravity. When the groundwater level rises, the groundwater flows through the reserved seepage openings 6 in the tank shell 1 and into the water storage buffer between the tank shell 1 and the internal soft layer 4, where its buoyancy directly acts on the internal soft layer 4. When the groundwater level drops, the groundwater flows back into the soil through the reserved seepage openings 6 in the tank shell 1, and the internal soft layer 4, simultaneously returning to its original position under the gravity of the sewage or fertilizer water within the tank shell 1.

[0017] The present invention is easy to install: by arranging the water seepage port 6 on the outside of the tank body and arranging the soft layer on the inside, the floating of the tank body caused by the change of the groundwater level is offset, thereby avoiding damage to the connecting pipes and even the tank body itself.

[0018] The present invention also discloses a method for using an anti-floating underground tank structure, comprising the following steps: S1. When the groundwater level rises, groundwater enters the water storage buffer zone between the tank shell 1 and the built-in soft layer 4 through the reserved seepage port 6 of the tank shell 1, and the buoyancy directly acts on the built-in soft layer 4.

[0019] S2. When the groundwater level drops, the groundwater returns to the soil through the reserved seepage port 6 of the tank shell 1. At the same time, the built-in soft layer 4 returns to its original position under the gravity of the fertilizer water in the tank shell 1.

[0020] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
