Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, to a regulating water storage tank structure. Background Technology

[0002] In modern agricultural irrigation, water storage ponds are often set up in irrigation areas to ensure stable and reliable irrigation.

[0003] During the flood season, when river flows are high, floodwaters can be transported to the vicinity of the regulating reservoir via the river diversion canal and irrigation channels, and then pumped into the reservoir by booster pumps. When crops need irrigation, water can be released from the regulating reservoir. This model effectively solves the problem of "mismatch between incoming and outgoing water" in irrigation. However, when floodwaters are diverted to replenish the regulating reservoir during the flood season, a large amount of silt will be deposited in it, which over time occupies a significant portion of the reservoir's volume and severely reduces its effective storage capacity.

[0004] In related technologies, manual dredging is only carried out after the sediment in the water storage tank has accumulated to a certain extent, which increases the operation and maintenance costs of the water storage tank. Utility Model Content

[0005] The problem this invention addresses is how to effectively reduce the operation and maintenance costs of water storage tanks.

[0006] To solve the above problems, this utility model provides a regulating water storage tank structure, comprising: The dam body includes a dam crest and an upstream dam slope, the top of which is connected to the dam crest; The pool bottom structure is connected to the bottom end of the upstream dam slope, and the height of the end of the pool bottom structure closer to the upstream dam slope is higher than the height of the other end of the pool bottom structure farther away from the upstream dam slope; The sediment discharge channel includes a channel body and a valve structure. One end of the channel body is located inside the dam body and communicates with the bottom structure of the pool. The other end of the channel body extends outside the dam body. The valve structure is installed in the channel body and is used to discharge sediment from the bottom structure of the pool into the channel body to the outside of the bottom structure when the valve structure is open.

[0007] Optionally, the corridor body includes a sand inlet, a box culvert top slab, a box culvert bottom slab, and box culvert sidewalls. The box culvert top slab, the box culvert bottom slab, and the box culvert sidewalls form a sand inlet channel. One end of the sand inlet channel is connected to the sand inlet, and the other end of the sand inlet channel is provided with the valve structure.

[0008] Optionally, the bottom plate of the box culvert is set at an angle to the horizontal plane.

[0009] Optionally, the corridor body further includes a guide plate, which is fixedly installed inside the sand inlet and is set at an angle to the bottom plate of the box culvert.

[0010] Optionally, the upstream dam slope includes an upstream dam slope body and a first protective structure, the top of the upstream dam slope body is connected to the dam crest, and the first protective structure is fixedly covered on the surface of the upstream dam slope body.

[0011] Optionally, the upstream dam slope further includes an anti-slide wall, which is disposed between the bottom end of the upstream dam slope body and the pool bottom structure, and the top end of the anti-slide wall is higher than or flush with the bottom end of the first protective structure. The anti-slide wall is used to prevent the first protective structure and the upstream dam slope body from sliding down.

[0012] Optionally, the regulating reservoir structure further includes a first sealing structure, wherein the first sealing structure is respectively provided between the bottom end of the upstream dam slope body and the anti-slide wall, and between the anti-slide wall and the bottom structure of the reservoir.

[0013] Optionally, the pool bottom structure includes a pool bottom body, which is funnel-shaped.

[0014] Optionally, the bottom of the pool body is provided with a water outlet, the sand inlet is embedded in the water outlet, and a second sealing structure is provided between the sand inlet and the water outlet.

[0015] Optionally, the pool bottom structure further includes a second protective structure, which is fixedly covered on the surface of the pool bottom body.

[0016] The beneficial effects of the regulating water storage tank structure of this utility model are: The reservoir structure may include a dam body, a reservoir bottom structure, and a sediment discharge channel. During the flood season, floodwaters from the river channel are transported to the reservoir structure for storage. When irrigation is needed for farmland, water is released from the reservoir structure for irrigation. Specifically, the dam crest, located at a higher position within the dam body, acts as a water barrier, while the upstream dam slope, lower than the crest, provides seepage prevention and protection for the dam body. Since the height of the end of the reservoir bottom structure near the upstream dam slope is higher than the height of the other end, in other words, the edge of the reservoir bottom structure is higher than the bottom structure. In the central area of ​​the reservoir, the sloping surface of the bottom structure is used to collect floodwater sediment in the lower central area of ​​the bottom structure. Since one end of the channel body is located within the dam body and connected to the bottom structure, when the valve structure is open, the sediment in the central area of ​​the bottom structure can quickly enter the channel body under its own gravity and be discharged to the outside of the bottom structure through the open valve structure. This achieves automatic sediment removal of the reservoir structure, eliminating the need for manual dredging and effectively reducing the operation and maintenance costs of the reservoir structure. Furthermore, since the edge of the bottom structure is higher than the central area, the bottom structure can be essentially funnel-shaped, effectively increasing the volume of the entire reservoir structure, allowing it to store more water and achieve greater benefits.

[0021] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0022] In response to the problems existing in the aforementioned related technologies, such as Figure 1 and Figure 2 As shown, this utility model embodiment provides a regulating water storage tank structure, which includes: The dam body 1 includes a dam crest 12 and an upstream dam slope 11, the top of which is connected to the dam crest 12; Pool bottom structure 3 is connected to the bottom end of the upstream dam slope 11. The height of the pool bottom structure 3 at one end close to the upstream dam slope 11 is higher than the height of the other end of the pool bottom structure 3 away from the upstream dam slope 11. The sediment discharge channel 2 includes a channel body 21 and a valve structure 22. One end of the channel body 21 is located inside the dam body 1 and communicates with the bottom structure 3 of the pool. The other end of the channel body 21 extends outside the dam body 1. The valve structure 22 is disposed on the channel body 21. When the valve structure 22 is in the open state, it allows the sediment entering the bottom structure 3 of the pool to be discharged to the outside of the bottom structure 3.

[0023] Specifically, the dam body 1 is the main body of the entire regulating reservoir structure, consisting of the entire entity from the foundation to the top. Among them, the upstream dam slope 11 is the sloping side of the dam body 1 facing the reservoir water (such as the bottom structure 3), and the dam crest 12 is the top surface of the dam body 1.

[0024] The top and bottom of the upstream dam slope 11 are respectively connected to the dam crest 12 and the pool bottom structure 3.

[0025] The height of the end of the pool bottom structure 3 that is close to the upstream dam slope 11 and higher than the height of the other end of the pool bottom structure 3 that is far away from the upstream dam slope 11 can be understood as the edge of the pool bottom structure 3 being higher than the middle area of ​​the pool bottom structure 3.

[0026] The corridor body 21 is used to discharge the silt and sand in the floodwater inside the pool bottom structure 3 to the outside of the pool bottom structure 3.

[0027] A valve structure 22 can be installed on the part of the corridor body 21 that extends outside the dam body 1. The valve structure 22 is used to control whether the flood (water flow) inside the corridor body 21 is discharged. The valve structure 22 can be a manual valve, which can be opened or closed by manual operation, or it can be an electric valve (an electrically controlled valve that can control the opening and closing of the pipeline can be used, which will not be described in detail here). Any valve that can discharge the silt inside the corridor body 21 is suitable for this technical solution.

[0028] When the water storage tank is storing water, the valve structure 22 is in a closed state, which serves to block the water flow in the corridor body 21; when the water storage tank is draining water, the valve structure 22 is in an open state, so as to use the water flow to discharge the silt in the corridor body 21, thereby realizing water discharge and silt removal operations.

[0029] Figure 1 The diagram in the middle is a top-down view of the water storage tank structure, while most of the structure of the corridor body 21 is located within the dam body 1. Figure 1 The main body of the corridor 21 is represented by a dashed line.

[0030] Figure 2 The letter S in the text can represent the normal water level within the regulating reservoir structure.

[0031] In this embodiment, the regulating reservoir structure may include a dam body 1, a reservoir bottom structure 3, and a sediment discharge corridor 2. Floodwater from the river during the flood season can be transported to the regulating reservoir structure for storage. When farmland needs irrigation, water can be released from the regulating reservoir structure for irrigation. Specifically, the dam crest 12, located at a higher position in the dam body 1, acts as a water barrier, while the upstream dam slope 11, lower than the dam crest 12, provides seepage prevention and protection for the dam body 1. Since the height of the end of the reservoir bottom structure 3 closest to the upstream dam slope 11 is higher than the height of the other end of the reservoir bottom structure 3 furthest from the upstream dam slope 11, in other words, the edge of the reservoir bottom structure 3 is higher than... In the central area of ​​the pool bottom structure 3, the sloping surface of the pool bottom structure 3 is used to collect the sediment from the floodwaters in the lower central area. Since one end of the corridor body 21 is located inside the dam body 1 and connected to the pool bottom structure 3, when the valve structure 22 is open, the sediment in the central area of ​​the pool bottom structure 3 can quickly enter the corridor body 21 under its own gravity and be discharged to the outside of the pool bottom structure 3 through the open valve structure 22. This achieves automatic sediment removal from the water storage tank structure, eliminating the need for manual dredging and effectively reducing the operation and maintenance costs of the water storage tank structure. Furthermore, since the edge of the pool bottom structure 3 is higher than its central part, the pool bottom structure 3 can be basically funnel-shaped, which can effectively increase the volume of the entire water storage tank structure, allowing the water storage tank structure to store more water and exert greater benefits.

[0032] Optionally, combined Figure 2 and Figure 5 As shown, the corridor body 21 can adopt a rectangular box culvert structure. For example, the corridor body 21 includes a sand inlet 211, a box culvert top plate 212, a box culvert bottom plate 213, and a box culvert side wall 214. The box culvert top plate 212, the box culvert bottom plate 213, and the box culvert side wall 214 form a sand inlet channel. One end of the sand inlet channel is connected to the sand inlet 211, and the other end of the sand inlet channel is provided with the valve structure 22.

[0033] Specifically, the corridor body 21 may include two box culvert sidewalls 214 that are opposite to each other and spaced apart. Therefore, the box culvert top plate 212, the box culvert bottom plate 213 and the two box culvert sidewalls 214 can form a sand inlet channel. The sand flushing channel can be understood as a cavity structure inside the corridor body 21. One end of the sand flushing channel is connected to the sand inlet 211, and the other end of the sand flushing channel extends out of the dam body 1. The valve structure 22 is set on the other end of the sand flushing channel.

[0034] In addition, the other end of the sand flushing channel can extend to the surrounding ditches.

[0035] The height of the sand inlet 211 can be set from 1m to 3m, preferably 2m; the thickness of the box culvert top plate 212, box culvert bottom plate 213 and box culvert side wall 214 can be set from 50cm to 80cm, and they are made of reinforced concrete.

[0036] In this optional embodiment, since the box culvert top slab 212, box culvert bottom slab 213 and two box culvert side walls 214 can form a corridor body 21 with a sand flushing channel, and the corridor body 21 is made of reinforced concrete, the structural strength of the corridor body 21 can be increased, the probability of deformation or collapse of the corridor body 21 can be reduced, and the service life of the corridor body 21 can be extended accordingly.

[0037] Optionally, combined Figure 2 and Figure 4 As shown, the bottom plate 213 of the box culvert is set at an angle to the horizontal plane.

[0038] Specifically, the bottom plate 213 of the box culvert is set at an angle to the horizontal plane. This can be understood as the bottom plate 213 of the box culvert having a certain slope relative to the horizontal plane, and the end of the bottom plate 213 of the box culvert that is closer to the sand inlet 211 is higher than the other end of the bottom plate 213 that is farther away from the sand inlet 211.

[0039] The flow velocity of flushing sand in the flushing channel can be controlled between 3 m / s and 5 m / s.

[0040] The angle between the bottom plate 213 of the box culvert and the horizontal plane can range from 3 degrees to 30 degrees.

[0041] Combination Figure 2 As shown, the dam body 1 also includes a downstream dam slope 13, which is the sloping side of the dam body 1 facing away from the reservoir. A part of the upstream dam slope 11, the pool bottom structure 3, and the entire gallery body 21 are all below the ground line 5, while a part of the upstream dam slope 11, a part of the downstream dam slope 13, and the dam crest 12 are all above the ground line 5. Figure 2 The ground line is the original, unexcavated, and unfilled natural surface outline of the site before construction begins; therefore, the ground line is represented by a dashed line.

[0042] In this optional embodiment, since the bottom plate 213 of the box culvert is set at an angle to the horizontal plane, the bottom plate 213 of the box culvert has a certain slope, so that the slope of the bottom plate 213 of the box culvert can be used to make the flow velocity of the water in the sand flushing channel of the main body 21 of the sand flushing meet the sand flushing flow velocity requirements.

[0043] Optionally, combined Figure 4 As shown, the corridor body 21 also includes a guide plate 215, which is fixedly installed inside the sand inlet 211 and is set at an angle to the bottom plate 213 of the box culvert.

[0044] Specifically, the sand inlet 211 can be an arc-shaped pipe joint at a certain angle, and the guide plate 215 can be fixedly installed inside the sand inlet 211 through a reinforced concrete structure, and the guide plate 215 and the bottom plate 213 of the box culvert can be set at a certain angle.

[0045] The angle between the guide plate 215 and the bottom plate 213 of the box culvert near the sand inlet 211 can be between 30 degrees and 80 degrees.

[0046] In this optional embodiment, by fixing and installing a guide plate 215 arranged at an angle to the bottom plate 213 of the box culvert inside the sand inlet, the silt in the bottom structure 3 can quickly enter the flushing channel along the slope of the guide plate 215 during the process of entering the sand inlet 211 of the corridor body 21. This not only accelerates the flow of water and silt into the flushing channel, but also reduces the probability of silt accumulation at the sand inlet 211.

[0047] Optionally, combined Figure 4 As shown, the upstream dam slope 11 includes an upstream dam slope body 111 and a first protective structure 112. The top of the upstream dam slope body 111 is connected to the dam crest 12, and the first protective structure 112 is fixedly covered on the surface of the upstream dam slope body 111.

[0048] Specifically, the first protective structure 112 may be a concrete structure with a certain thickness, for example, 0.2m.

[0049] The first protective structure 112, such as a concrete structure, can be fixed and covered on the surface of the upstream dam slope body 111 by pouring.

[0050] The slope ratio of the upstream dam slope 111 can range from 1:1.5 to 1:3, and the slope ratio of the downstream dam slope 13 can range from 1:1.5 to 1:2.5.

[0051] In this optional embodiment, since the top of the upstream dam slope body 111 is connected to the dam crest 12, and the first protective structure 112 is fixedly covered on the upstream dam slope body 111, in other words, the entire upper part of the upstream dam slope body 111 on the water-facing side of the dam crest 12 is fixedly covered by the first protective structure 112, which can effectively play a role in preventing seepage and protecting the dam body 1.

[0052] Optionally, combined Figure 3 As shown, the upstream dam slope 11 also includes a sliding wall 113, which is located between the bottom end of the upstream dam slope body 111 and the pool bottom structure 3. The top end of the sliding wall 113 is higher than or level with the bottom end of the first protective structure 112. The sliding wall 113 is used to prevent the first protective structure 112 and the upstream dam slope body 111 from sliding down.

[0053] Specifically, the anti-slip wall 113 can be made of plain concrete or reinforced concrete.

[0054] An anti-slide wall 113 is fixedly installed between the bottom end of the upstream dam slope body 111 (i.e. the end away from the dam top 12) and the pool bottom structure 3.

[0055] In this optional embodiment, by setting the anti-slide wall 113 between the bottom end of the upstream dam slope body 111 and the pool bottom structure 3, the anti-slide wall 113 blocks the upstream dam slope body 111 and the first protective structure 112, thereby preventing the upstream dam slope body 111 and the first protective structure 112 from sliding down the slope surface of the upstream dam slope 11. Since the top of the anti-slide wall 113 is higher than or level with the bottom end of the first protective structure 112, the anti-slide wall 113, which has a certain height, can prevent the upstream dam slope body 111 and the first protective structure 112 from sliding down, and also block the debris generated in the upstream dam slope body 111 and the first protective structure 112 at the upstream dam slope 11.

[0056] Optionally, the regulating reservoir structure also includes a first sealing structure 4, which is respectively provided between the bottom end of the upstream dam slope body 111 and the anti-slide wall 113, and between the anti-slide wall 113 and the bottom structure 3 of the reservoir.

[0057] Specifically, the first sealing structure 4 can adopt the following structure, such as closed-cell foam board and sealant (e.g., polyurethane sealant). The closed-cell foam board is a building material with an independent closed-cell bubble structure. The honeycomb-like pores on the outside are evenly distributed, which can be firmly and tightly integrated with cement adhesive. It can naturally adapt to changes in expansion and contraction, thereby enhancing the expansion and water-stopping effect. The sealant is used to stably fix the closed-cell foam board between the bottom end of the upstream dam slope body 111 and the anti-slip wall 113, and between the anti-slip wall 113 and the pool bottom structure 3.

[0058] In this optional embodiment, since the first sealing structure 4 is fixedly installed between the bottom end of the upstream dam slope body 111 and the anti-slide wall 113, and between the anti-slide wall 113 and the pool bottom structure 3, the sealing effect between the upstream dam slope body 111 and the anti-slide wall 113, and between the anti-slide wall 113 and the pool bottom structure 3 can be effectively increased through the first sealing structure 4, preventing water and sediment from entering the reservoir structure from the river channel from entering the gaps between the upstream dam slope body 111 and the anti-slide wall 113, and between the anti-slide wall 113 and the pool bottom structure 3, and correspondingly extending the sealing effect of the reservoir structure.

[0059] Optionally, combined Figure 1 and Figure 4 As shown, the pool bottom structure 3 includes a pool bottom body 31, which is funnel-shaped.

[0060] Specifically, the pool bottom body 31 can adopt a conical funnel structure, and the slope ratio of the pool bottom body 31 is generally 1:5 to 1:20.

[0061] In this optional embodiment, the bottom body 31 is configured as a funnel shape, which not only serves to prevent seepage of the bottom body 31, but also allows the deposited silt to be collected at the center of the bottom body 31 by utilizing the conical funnel slope of the bottom body 31, facilitating sand discharge; at the same time, making the bottom body 31 into a funnel shape can also effectively increase the volume of the regulating water tank structure, enabling it to store more water and exert greater benefits.

[0062] Optionally, the bottom end of the pool body 31 is provided with a water outlet, the sand inlet 211 is embedded in the water outlet, and a second sealing structure is provided between the sand inlet 211 and the water outlet.

[0063] Specifically, the bottom end of the pool bottom body 31 refers to the lowest part of the pool bottom body 31; an outlet can be opened at the bottom end of the pool bottom body 31, and the diameter of the sand inlet 211 of the corridor body 21 can be smaller than the diameter of the outlet, so that the sand inlet 211 of the corridor body 21 can be smoothly embedded in the interior of the outlet.

[0064] The second sealing structure can be the same type as or different from the first sealing structure 4.

[0065] The second sealing structure can be a closed-cell foam board and a sealant (such as polyurethane sealant), with the closed-cell foam board wrapped around the outside of the sand inlet 211.

[0066] In this optional embodiment, after the sand inlet 211 is embedded in the water outlet, the second sealing structure can be located between the sand inlet 211 and the water outlet. Subsequently, a closed-cell foam board can be poured into the space between the sand inlet 211 and the water outlet to fix the closed-cell foam board between the sand inlet 211 and the water outlet, thereby improving the sealing effect between the sand inlet 211 and the water outlet.

[0067] Optionally, combined Figure 3 As shown, the pool bottom structure 3 also includes a second protective structure 32, which is fixedly covered on the surface of the pool bottom body 31.

[0068] Specifically, the second protective structure 32 may be a concrete structure with a certain thickness, for example, 0.2m.

[0069] The second protective structure 32, such as a concrete structure, can be fixed and covered on the surface of the pool bottom body 31 by casting.

[0070] The slope ratio of the pool bottom structure 3 can range from 1:5 to 1:20.

[0071] In this optional embodiment, since the second protective structure 32 is fixedly covered on the surface of the pool bottom body 31, it can effectively play a role in preventing seepage and protecting the pool bottom body 31.

[0072] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
